Introduction: Endoscopic retrograde cholangiopancreatography (ERCP) is a therapeutic procedure for various biliopancreatic pathologies. There are different training centers with a variety of practice times for performing ERCP. Objective: This study aims to evaluate the initial post-training results in therapeutic endoscopy at the Chilean-Japanese Institute of San Borja Arriarán Hospital, analyzing 150 consecutive ERCP procedures performed between November 2017 and January 2019 by a single operator at a hospital in La Araucanía, describing technical aspects, morbidity, and mortality. Method: Retrospective analysis of the prospective registry of the first 150 consecutive ERCP cases performed at the San José de Victoria Hospital (HSJV). Clinical, technical and laboratory variables were measured. Descriptive statistics were produced with measures of central tendency, dispersion and extreme tendency. Results: Series of 150 patients undergoing ERCP: mean age 60.1 years, median 65 and extreme ages 16-98 years. Female sex 69.3%. ERCP indications: 67.3% choledocholithiasis without cholangitis, 16.7% acute cholangitis, 6% benign bile duct stenosis, 3.3% periampullary tumor. All supported by an anesthetist, 50.7% propofol and 49.3% general anesthesia. Biliary cannulation rate 96.7%. Precut 19.3%. Reported complications reached 4.67%, with no mortality from the procedure in the series. Conclusions: The results of this series show that the training obtained by the professional improves the standards proposed for an effective and safe procedure, highlighting a cannulation rate of 96.7%, higher than what international guidelines describe as successful. The morbidity associated with ERCP in our series is comparable to national and international figures.
RESUMO
RESUMEN El hematoma subcapsular hepático es una complicación infrecuente pero potencialmente grave de la colangiografía retrógrada endoscópica. Por otra parte, las complicaciones derivadas del hematoma pueden ser su rotura, con el consiguiente sangrado masivo, y/o la trombosis portal por compresión que evolucione hacia la necrosis, la cual es susceptible de infecciones generalmente graves que requieren un manejo más enérgico. Presentamos el caso de una paciente a quien se le realizó una colangiografía endoscópica retrógrada por una colangitis aguda, y presentó en la evolución un hematoma subcapsular, que progresó a la necrosis hepática por compresión del pedículo portal, y una infección de esa necrosis, por lo que requirió una hepatectomía derecha de urgencia.
ABSTRACT Hepatic subcapsular hematoma is a rare but potentially lethal complication of endoscopic retrograde cholangiography. On the other hand, complications derived from the hematoma can be its rupture with the consequent massive bleeding, and/or portal thrombosis due to compression that evolves towards necrosis, which is susceptible to generally serious infections that require more aggressive management. We present the case of a patient treated in our department who underwent retrograde endoscopic cholangiography as treatment for her acute cholangitis, presenting in the evolution a subcapsular hematoma that progressed to hepatic necrosis due to compression of the portal pedicle and later an infection of that necrosis. requiring an emergency right hepatectomy as surgical treatment.
RESUMO
ABSTRACT Background: Common bile duct (CBD) stones are known to complicate 10-15% of gallstone diseases. Endoscopic retrograde cholangiopancreatography (ERCP) is the therapeutic modality of choice for bile duct clearance in CBD stones but may fail to achieve stone clearance. This prospective study was done to identify the predictors of failure of CBD clearance with ERCP. Objective: This prospective study was done to identify the predictors of failure of CBD clearance with ERCP. Methods: All consecutive patients with bile duct stones undergoing ERCP at a tertiary care center were prospectively included from October 2020 to October 2021. The study's primary outcome was to identify and analyze factors that could predict the failure of complete CBD clearance. Results: A total of 120 patients (50.8% males, median age: 53.5 years) were included in the final analysis. Successful clearance of CBD stones during the index procedure was achieved in 70% of patients. At a cut-off stone diameter of >10.5 mm and CBD diameter of >12.5 mm, the AUC was 0.890 and 0.884, respectively, to predict failed clearance of CBD. On multivariate analysis, stone diameter ≥15 mm [odds ratio (OR) 16.97, 95% confidence interval (CI): 1.629-176.785], location of stones in hepatic ducts (OR 7.74, 95%CI: 2.041-29.332), presence of stricture distal to stone (OR 6.99, 95%CI: 1.402-34.726) and impacted stone (OR 21.61, 95%CI: 1.84-253.058) were independent predictors of failed bile duct clearance. Conclusion: Stone size and location are independent predictors of failed bile duct clearance. The endoscopist should consider these factors while subjecting a patient to biliary ductal clearance to plan additional intervention.
RESUMO Contexto: Cálculos do ducto biliar comum (CDC) são conhecidos por complicar 10-15% das doenças de cálculos biliares. A colangiopancreatografia retrógrada endoscópica (CPRE) é a modalidade terapêutica de escolha para a limpeza do CDC, mas pode falhar na sua remoção. Objetivo: Este estudo prospectivo foi realizado para identificar os previsores de falha na limpeza do CDC com CPRE. Métodos: Pacientes consecutivos com cálculos no ducto biliar submetidos a CPRE em um centro de atendimento terciário foram incluídos prospectivamente de outubro de 2020 a outubro de 2021. O principal resultado do estudo foi identificar e analisar fatores que poderiam prever a falha na limpeza completa do CDC. Resultados: Um total de 120 pacientes (50,8% homens, idade média: 53,5 anos) foram incluídos na análise final. A limpeza bem-sucedida dos cálculos de CDC durante o procedimento inicial foi alcançada em 70% dos pacientes. Com um diâmetro de corte de cálculos >10,5 mm e de diâmetro de CDC de >12,5 mm, a AUC foi de 0,890 e 0,884, respectivamente, para prever a falha na limpeza do CDC. Na análise multivariada, diâmetro da cálculos ≥15 mm [razão de chances (OR) 16,97, intervalo de confiança de 95% (IC): 1,629-176,785], localização dos cálculos nos ductos hepáticos (OR 7,74, IC95%: 2,041-29,332), presença de estreitamento distal ao cálculo (OR 6,99, IC95%: 1,402-34,726) e cálculo impactado (OR 21,61, IC95%: 1,84-253,058) foram previsores independentes de falha na limpeza do ducto biliar. Conclusão: O tamanho e a localização dos cálculos são previsores independentes de falha na limpeza do ducto biliar. O endoscopista deve considerar esses fatores ao submeter um paciente à limpeza ductal biliar para planejar intervenção adicional.
RESUMO
ABSTRACT Background: Acute pancreatitis following surgical or endoscopic procedures on the pancreas can compromise the outcome and lead to severe complications and even death. The aim of this study was to determine whether prolonged fasting affects the severity of acute pancreatitis (AP). Methods: Male mice were divided into 4 groups: Group CF (n=5) control animals that fasted for 24 hours; Group CNF (n=5) control animals that did not fast; Group APF (n=7) that fasted for 24 hours and underwent induction of acute pancreatitis (AP) and Group APNF (n=7) that did not fast and underwent AP. Eight hours after AP blood was collected for evaluation of cytokines: IL-1β, IL-6, IL-10, TNF-α and MCP-1. Liver tissue was collected for determination of Malondialdehyde, pancreatic tissue for determination of enzyme content and lung tissue for determination of myeloperoxidase. Results: Significant increase in pancreatic amylase content was observed in group CF and increased serum levels of IL -6, Il-10 and MCP-1 were in group APF. Liver malondialdehyde was also increased in APF animals. APF group showed much more necrosis of the pancreatic acinar cells. Conclusion: In the present study, we observed an increase in the severity of acute pancreatitis with prolonged fasting in a severe acute pancreatitis model. These results suggest that in clinical practice, the preoperative fasting time should be shortened before pancreatic procedures.
RESUMO Contexto: A pancreatite aguda após procedimentos cirúrgicos ou endoscópicos no pâncreas pode comprometer o resultado e levar a complicações graves e até mesmo à morte. O objetivo deste estudo foi determinar se o jejum prolongado afeta a gravidade da pancreatite aguda (PA). Métodos: Camundongos machos foram divididos em 4 grupos: Grupo CF (n=5) animais de controle que jejuaram por 24 horas; Grupo CNF (n=5) animais de controle que não jejuaram; Grupo APF (n=7) que jejuaram por 24 horas e foram submetidos à indução de PA e Grupo APNF (n=7) que não jejuaram e foram submetidos a PA. Oito horas após a PA, o sangue foi coletado para avaliação de citocinas: IL-1β, IL-6, IL-10, TNF-α e MCP-1. O tecido hepático foi coletado para a determinação do malondialdeído, o tecido pancreático para a determinação do conteúdo enzimático e o tecido pulmonar para a determinação da mieloperoxidase. Resultados: Foi observado um aumento significativo no conteúdo de amilase pancreática no grupo CF e um aumento nos níveis séricos de IL-6, Il-10 e MCP-1 no grupo APF. O malondialdeído hepático também aumentou nos animais APF. O grupo APF apresentou muito mais necrose das células acinares pancreáticas. Conclusão: No presente estudo, observamos um aumento na gravidade da pancreatite aguda com o jejum prolongado em um modelo de pancreatite aguda grave. Esses resultados sugerem que, na prática clínica, o tempo de jejum pré-operatório deve ser reduzido antes dos procedimentos pancreáticos.
RESUMO
BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) is an endoscopic study in which the duodenum is observed laterally, and the bile duct is instrumented. There are several indications and complications in the procedure. OBJECTIVE: To determine the incidence of duodenal perforations, using the Stapfer classification in the Hospital Juárez de Mexico over a period of 5 years, as well as the management implemented in such cases. METHOD: The study was carried out at the Hospital Juárez de Mexico of the Ministry of Health. All patients who underwent ERCP between January 1, 2017, to May 30, 2022 were included. RESULTS: 485 ERCP were performed in the study period. Incidence of 1.6% post-ERCP duodenal perforation. The average age of the subjects 56.37 years. In-hospital stay of post-ERCP perforations averaged 9.37 days. The time of the endoscopic study at the time of the surgical procedure is 10 h on average. CONCLUSIONS: Post-ERCP duodenal perforation is a complication that occurs with a low incidence, it tends to increase the number of days of in-hospital stay and increases morbimortality of patients; therefore, it is important to be always alert.

INTRODUCTION AND AIM: Endoscopic retrograde cholangiopancreatography (ERCP) is a complex procedure. Clinical guidelines assess competence in ERCP through a defined number of procedures, but multiple factors are involved. Our aim was to analyze the morphology of the papilla of Vater as an independent factor in selective common bile duct cannulation during resident training. MATERIAL AND METHODS: Patients that underwent ERCP were studied consecutively. All ERCPs were begun by a resident in training. The type of papilla was classified according to Haraldsson, including those with previous sphincterotomy. Cannulation difficulty and success and their relation to the type of papilla were documented. The analysis was divided into three 4-month periods. RESULTS: Of the 429 patients, cannulation was difficult in 101 (23.5%). The residents achieved selective cannulation of the common bile duct in 276 (64.3%) and the cannulation success rate at the end of their training was 81.7%. Cannulation was performed with the least difficulty in papillae with previous sphincterotomy (2.8%), unlike the type 4 papilla, which was difficult to cannulate in 50% of the cases. The lowest overall cannulation success was in the type 2 papilla (81.8%). CONCLUSION: Papilla type can influence cannulation success, but it is not the only related factor. Patients that underwent previous sphincterotomy appear to be the cases in whom ERCP training can be started.
RESUMO

A continuación, se presentan 2 casos, los cuales debutan con cuadro clínico de dolor en hipocondrio derecho y con datos clínicos y de laboratorio de obstrucción de la vía biliar, y que mediante estudio de colangio resonancia, se evidencian múltiples litos endoluminales de la vía biliar de manera global, además se muestra del tratamiento de uno de los casos mediante CPRE con evacuación exitosa de los cálculos biliares.
Abstract The joint and massive presence of gallstones from the bile duct, both intra and extra hepatic, is a rare entity within the western population. Two cases are presented below, which debuted with a clinical picture of pain in the right hypo chondrium and with a clinical picture of pain in the right hypochondrium and with clinical and laboratory data of bile duct obstruction, and that by means of a resonance cholangiography study, multiple endoluminal stones of the bile duct are evidenced. Overall, it also shows the treatment of one of the cases by ERCP with successful evacuation of the gallstones.
RESUMO
RESUMEN La colangiopancreatografía retrógrada endoscópica (CPRE) es un procedimiento invasivo para el diagnóstico y el tratamiento de la enfermedad biliopancreática. Entre sus complicaciones más infrecuentes se encuentra la migración proximal y distal de la endoprótesis biliar. Las escasas publicaciones sobre tal complicación motivaron la redacción de este artículo. Nuestro objetivo principal fue presentar dos casos clínicos de migración de endoprótesis biliar plástica, su manejo y resolución. Consideramos importante resaltar la necesidad del registro y seguimiento de los pacientes en quienes se colocaron endoprótesis biliares, para la prevención de su olvido más allá del tiempo recomendado de permanencia, y evitar así complicaciones tardías, ya que "la ignorancia no es la felicidad".
ABSTRACT Endoscopic retrograde cholangiopancreatography (ERCP) is an invasive procedure for the diagnosis and treatment of biliary tract and pancreatic duct diseases. Proximal and distal stent migration is a rare complication. The paucity of publications on this issue motivated this article. The main aim of this study was to describe two case reports of migration of biliary plastic stents, how they were managed and solved. We believe it is important to emphasize the need for recording and monitoring patients who have undergone biliary stent placement, to avoid leaving the stent in situ beyond the recommended time, and thus avoid late complications, since "ignorance is not bliss".
RESUMO
Resumen Introducción: la fistula biliar poscolecistectomía es poco frecuente. El manejo principalmente es endoscópico, pero en la literatura no hay consenso en la técnica de primera línea entre papilotomía, prótesis biliar o su combinación. Metodología: se realizó un estudio observacional tipo serie de casos en el que se incluyeron todas las CPRE realizadas en el Hospital Universitario San Ignacio en Bogotá, Colombia, entre enero de 2010 y marzo del 2021 por fistula biliar posterior a colecistectomía. Se registraron las características demográficas, manifestaciones clínicas, resolución, eventos adversos y estancia hospitalaria según la técnica endoscópica. Resultados: se incluyeron 24 pacientes con fistula biliar poscolecistectomía que se manejaron con CPRE. La mediana de edad fue de 59 años (rango intercuartílico [RIC]: 53,5-67). En el 75% el tipo de cirugía fue laparoscópica. La manifestación clínica más frecuente fue aumento del drenaje biliar > 150 mL/24 horas (50%), seguido de dolor abdominal (39%). La principal localización fue el conducto cístico en el 40%. El manejo con papilotomía fue del 25%; con prótesis biliar, 8,4%, y combinado, 66%; la resolución de la fístula ocurrió en el 100%, 50% y 87%, respectivamente, con menor estancia hospitalaria en el manejo combinado de 3,5 días frente a 4 días en papilotomía. Solo se presentó 1 evento adverso de hemorragia en el grupo de papilotomía. Conclusión: la papilotomía y la terapia combinada son opciones terapéuticas con buenas tasas de resolución y baja estancia hospitalaria para el manejo de las fistulas biliares poscolecistectomía. Se requerirán estudios prospectivos, aleatorizados y multicéntricos para definir la técnica con mejores desenlaces clínicos.
Abstract Introduction: Postcholecystectomy biliary leak is rare. Management is mainly endoscopic, but in the literature, there is no consensus on the first-line technique between sphincterotomy, biliary stent, or combination. Materials and methods: A case series study was conducted that included all ERCP performed at the San Ignacio University Hospital in Bogotá, Colombia, between January 2010 and March 2021 due to biliary leak after cholecystectomy. Demographic characteristics, clinical manifestations, resolution, adverse events, and hospital length stay were recorded according to the endoscopic technique. Results: 24 patients with postcholecystectomy biliary leak managed with ERCP were included. The median age was 59 years (interquartile range [IQR]: 53.5-67). In 75% the surgery was laparoscopic. The most frequent clinical manifestation was increased biliary drainage > 150 mL/24 hours (50%), followed by abdominal pain (39%). The main fistula's location was the cystic duct in 40%. Management with sphincterotomy was 25%, with a biliary stent, 8.4%, and combined, 66%; leak resolution occurred in 100%, 50%, and 87%, respectively, with a shorter hospital length stay in the combined management of 3.5 days compared to four days in sphincterotomy. Only one adverse bleeding event occurred in the sphincterotomy group. Conclusion: Sphincterotomy and combined therapy are options with reasonable resolution rates and low hospital length stay for managing postcholecystectomy biliary leak. Prospective, randomized, and multicenter trials will be required to define the best technique.
RESUMO
ABSTRACT Background This multicenter multinational RCT designed to compare the efficacy of suppository indomethacin and NAC for prevention of PEP. Methods: During a 6-month period, all of the ERCP cases in seven referral centers were randomly assigned to receive either 1200 mg oral NAC, indomethacin suppository 100 mg, 1200 mg oral NAC plus indomethacin suppository 100 mg or placebo 2 hours before ERCP. The primary outcomes were the rate and severity of any PEP. Results: A total of 432 patients included (41.4% male). They were originally citizens of 6 countries (60.87% Caucasian). They were randomly allocated to receive either NAC (group A, 84 cases), rectal indomethacin (group B, 138 cases), NAC + rectal indomethacin (group C, 115 cases) or placebo (group D, 95 cases). The rate of PEP in groups A, B and C in comparison with placebo were 10.7%, 17.4%, 7.8% vs 20% (P=0.08, 0.614 & 0.01 respectively). The NNT for NAC, indomethacin and NAC + indomethacin was 11, 38 and 8 respectively. Conclusion: Oral NAC is more effective than rectal indomethacin when compared to placebo for prevention of PEP and the combination of NAC and Indomethacin had the lowest incidence of PEP and may have synergistic effect in preventing of PEP (IRCT20201222049798N1; 29/12/2020).
RESUMO Contexto: Este estudo randomizado, controlado multicêntrico e multinacional foi projetado para comparar a eficácia da indometacina supositório e N-acetil cisteína (NAC) para prevenção de pancreatite pós colangiografia endoscópica. Métodos: Durante um período de 6 meses, todos os pacientes submetidos à CPRE em sete centros de referência foram aleatoriamente atribuídos para receber 1200 mg de NAC oral, supositório de indometacina 100 mg, 1200 mg de NAC oral mais supositório de indometacina 100 mg ou placebo 2 horas antes do procedimento. Os resultados primários foram a taxa e a gravidade de qualquer pancreatite pós procedimento (PPP). Resultados: Um total de 432 pacientes foram incluídos (41,4% do sexo masculino). Eram originalmente cidadãos de seis países (60,87% caucasianos). Foram alocados aleatoriamente para receber NAC (grupo A, 84 casos), indometacina retal (grupo B, 138 casos), NAC + indometacina retal (grupo C, 115 casos) ou placebo (grupo D, 95 casos). A taxa de PPP nos grupos A, B e C em comparação com o placebo foi de 10,7%, 17,4%, 7,8% vs 20% (P=0,08, 0,614 e 0,01, respectivamente). Conclusão A NAC oral é mais eficaz do que a indometacina retal quando comparado ao placebo para prevenção de PPP e a combinação de NAC e indometacina teve a menor incidência de PPP e pode ter efeito sinérgico na sua prevenção de PPP.

RESUMO
ABSTRACT BACKGROUND: A successful bile duct cannulation is a prerequisite for the realization of endoscopic retrograde cholangiopancreatography (ERCP). When biliary cannulation is not possible, needle-knife fistulotomy (NKF) can be performed. However, when biliary access is not successfully achieved even after performing NKF, it is possible to interrupt the procedure, and repeat the ERCP after a short interval. OBJECTIVE: The aim of this study is to analyze if repeating an ERCP after a short interval of 48 hours is effective in achieving biliary access after an initial NKF was unsuccessfully performed. METHODS: A total of 1024 patients with a naive papilla, that underwent ERCP between the years of 2009-2019, were retrospectively reviewed. Difficult biliary cannulation was identified in 238 of these cases and NKF was performed. Success of biliary cannulation, NKF success at the first and second ERCPs, the associations between the type of the papilla, biliary dilatation, and overall success of NKF and adverse events rates were evaluated. RESULTS: Biliary access was initially achieved in 183 (76.8%) cases. Of the 55 (23.1%) remaining cases a second attempt was performed after 48 hours, and biliary access was successfully achieved in 46 (83.6%) of them. The overall success of NKF after the first and second ERCP, the success rate was 96.2%. Papilla located out of its normal position was related to a minor chance of success at NKF (P<0.05). CONCLUSION: We conclude that when biliary access is not achieved after the performance of a NKF, a second attempt is safe and effective and should be attempted.
RESUMO CONTEXTO: A canulação biliar de sucesso é pré-requisito para a realização da colangiopancreatografia retrógrada endoscópica (CPRE). Quando a canulação biliar não é possível, a fistulotomia com auxílio do cateter Needle-Knife (NKF) pode ser realizada. Entretanto, quando o acesso biliar não é atingido mesmo após a realização de um NKF, é possível optar-se pela interrupção do procedimento, e pela repetição da CPRE após curto intervalo de 48 horas. OBJETIVO: O objetivo desse estudo é analisar se a repetição da CPRE após um curto intervalo de 48 horas é efetivo em atingir o acesso biliar, quando um NKF foi realizado inicialmente sem sucesso. MÉTODOS: Um total de 1024 pacientes com papila virgem de tratamento, submetidos à CPRE entre os anos de 2009-2019, foram retrospectivamente analisados. Canulação biliar difícil foi identificada em 238 deles, e NKF foi então realizado. Foram avaliadas as taxas de sucesso durante a canulação biliar, assim como durante a realização de NKF na primeira e segunda CPREs. A associação entre o tipo de papila, dilatação biliar e o sucesso final na realização do NFK também foi avaliada, assim como a presença de eventos adversos associados à realização do NKF. RESULTADOS: Dentre todos os NKF realizados, acesso biliar foi inicialmente atingido em 183 (76,8%) casos. Os 55 (23,1%) casos restantes, foram submetidos a uma segunda CPRE após 48 horas e o acesso biliar foi atingido em 46 (83,6%) deles, resultando em uma taxa final de sucesso, após a primeira e segunda CPREs, de 96,2%. Papila localizada fora da sua posição habitual foi relacionada a menor chance de sucesso durante a realização de NKF (P<0,05). CONCLUSÃO: Concluiu-se que quando o acesso biliar não pode ser atingido após a realização de um NKF, uma segunda CPRE é segura, efetiva e deve ser realizada.
RESUMO
Resumen La endosonografía endoscópica es una alternativa que sirve como guía para la realización de derivaciones biliodigestivas en los casos en los que la colangiopancreatografía retrógrada endoscópica (CPRE) ha fallado. Se han descrito técnicas como la coledocoduodenostomía o coledocoantrostomía guiadas por ultrasonografía endoscópica (USE). Se describe el caso de una paciente de 72 años con adenocarcinoma de páncreas, compromiso portal y de paredes duodenales, en quien se usó la CPRE para intentar una derivación paliativa y fue fallida, por lo cual se realizó la colocación de un stent metálico guiado por endosonografía endoscópica, con adecuada respuesta clínica al tratamiento. En conclusión, el procedimiento es seguro y la endosonografía es una vía alterna efectiva en los casos de CPRE fallidas para lograr derivaciones biliares en casos de obstrucción de la vía biliar de origen maligno.
Abstract Endoscopic endosonography is an alternative to guide biliodigestive shunting in cases where endoscopic retrograde cholangiopancreatography (ERCP) has failed. Techniques such as choledoduodenostomy or choledochoantrostomy guided by endoscopic ultrasonography have been described. This is the case of a 72-year-old patient with pancreatic adenocarcinoma, portal vein and duodenal wall involvement, in whom ERCP to try a palliative shunt failed. Therefore, a metal stent was placed using endoscopic endosonography, with adequate clinical response to the procedure and treatment. It is concluded that the procedure is safe and that endosonography is an effective alternative in cases of ERCP failure to achieve biliary bypass in cases of malignant biliary obstruction.

Resumen El tratamiento de la coledocolitiasis ha evolucionado de forma significativa desde que Robert Abbe realizó la primera coledocotomía y la exploración de las vías biliares en Nueva York, en 1889. La colangiopancreatografía retrógrada endoscópica (CPRE), que inicialmente fue un método diagnóstico, ahora solo tiene validez como método terapéutico. En la actualidad, los principales métodos diagnósticos son la colangioresonancia magnética (CRM) y la ultrasonografía endoscópica (USE). El tratamiento de la coledocolitiasis pasó de la técnica quirúrgica abierta -en la que, de forma rutinaria, se realizaba la coledocorrafia sobre un tubo de Kehr o tubo en T- a la endoscópica, mediante el uso de la CPRE, la esfinteroplastia y la instrumentación con balones y canastilla. Hoy en día se dispone de técnicas adicionales como la litotricia mecánica (LM) o extracorpórea, la dilatación con balón (DB) de gran tamaño y el Spyglass ® . La técnica laparoscópica se usa desde hace varios años, en diversas partes del mundo, para el tratamiento de la coledocolitiasis. Estudios recientes proponen incluso el cierre primario del colédoco o la coledocoduodenostomía, con lo cual no sería necesaria la utilización del tubo en T. Pero en muchos otros sitios, y por diversas razones, se continúa usando la exploración quirúrgica abierta y el tubo en T, que representa una importante opción en el tratamiento de algunos pacientes. Caso clínico: paciente masculino de 88 años, con coledocolitiasis recidivante, cálculo gigante de difícil manejo endoscópico y sepsis de origen biliar, que requirió drenaje quirúrgico abierto de urgencias. Se realizó una coledocotomía, y se dejó el tubo en T. Posteriormente, se efectuó un tratamiento exitoso conjunto, mediante instrumentación por el tubo en T, por parte de cirugía general, y CPRE, por gastroenterología.
Abstract The treatment of choledocholithiasis has evolved significantly since Robert Abbé performed the first bile duct exploration via choledochotomy in New York in 1889. Endoscopic retrograde cholangiopancreatography (ERCP), which was initially used for diagnosis, is now only valid as a therapeutic tool. Currently, the main diagnostic methods are magnetic resonance cholangiopancreatography (MRCP) and endoscopic ultrasound (EUS). The treatment of choledocholithiasis moved from the open surgery in which biliary stenting was routinely performed on a Kehr tube or T-tube, to the endoscopic technique using ERCP, sphincteroplasty and instrumentation with balloons and baskets. Additional techniques are now available such as mechanical or extra-corporeal lithotripsy, endoscopic papillary large balloon dilation and SpyGlass cholangioscopy. The laparoscopic technique has been used for several years in different parts of the world for the treatment of choledocholithiasis. Recent studies even propose performing the primary closure of the bile duct or choledochoduodenostomy, so that the T-tube is not necessary. However, in many other places, and for a variety of reasons, open exploratory surgery and the T-tube continue to be used, being an important option in the treatment of some patients. Case presentation: 88-year-old male patient with recurrent choledocholithiasis and a giant gallstone that was difficult to treat endoscopically, with sepsis of biliary origin, which required open surgical drainage at the emergency room. Choledocotomy was performed, and a T-tube was inserted at the site. Subsequently, a successful joint treatment was performed by the General Surgery Service and the Gastroenterology Service, using T-tube instrumentation and ERCP, respectively.

BACKGROUND: Post-ERCP pancreatitis (PEP) is the most common complication of Post-endoscopic retrograde cholangiopancreatography. OBJECTIVE: to demonstrate whether serum amylase and lipase values correlate with the presence and severity of PEP. METHOD: We conducted a retrospective, observational and analytical study of patients who underwent ERCP, those who developed pancreatitis were classified by severity according to the 2012 revised Atlanta criteria and their serum enzyme levels were analyzed. We used ROC (Receiver Operating Characteristics) curves to know the best enzyme cutoff points and analyzed their diagnostic yields. Chi-square, t-distribution and Mann-Whitney U test were used in the variable analysis and it was considered statistically significant when p < 0.05. RESULTS: A total 621 patients, 54 presented pancreatitis. For moderately severe and severe forms: lipase level of 1500 U/L had an area under the curve (AUC) = 0.827, 95% CI (0.67-0.98), sensitivity = 72.7%, specificity = 86%, negative predictive value = 92.5%, p < 0.05. Amylase level of 920 U/L presented AUC = 0.65, 95% CI (0.43-0.86), sensitivity = 63%, specificity = 67%, p > 0.05. CONCLUSIONS: Serum lipase shows correlation with the presence and severity of PEP. Amylase shows no significant correlation with PEP.
ANTECEDENTES: La pancreatitis poscolangiopancreatografía retrógrada endoscópica (PPCPRE) es la complicación más frecuente de este procedimiento. OBJETIVO: Demostrar si la amilasa y la lipasa séricas se correlacionan con la presencia y la gravedad de la PPCPRE. MÉTODO: Realizamos un estudio retrospectivo, observacional y analítico de pacientes a quienes se realizó CPRE. Los que desarrollaron pancreatitis se clasificaron por gravedad de acuerdo con la revisión de Atlanta de 2012 y se analizaron sus concentraciones séricas de enzimas. Empleamos curvas ROC (Receiver Operating Characteristics) para conocer los mejores puntos de corte enzimáticos y analizamos sus rendimientos diagnósticos. Usamos las pruebas de ji al cuadrado, t de Student y U de Mann Whitney para el análisis de las variables, y se consideró estadísticamente significativo un valor de p < 0.05. RESULTADOS: De un total de 621 pacientes, 54 presentaron pancreatitis. Para pancreatitis moderadamente grave y grave, unas cifras de lipasa de 1500 U/l presentaron un área bajo la curva (AUC) = 0.827 (intervalo de confianza del 95% [IC 95%]: 0.67-0.98), con una sensibilidad del 72.7%, una especificidad del 86% y un valor predictivo negativo del 92.5% (p < 0.05); y unas cifras de amilasa de 920 U/l presentaron un AUC = 0.65 (IC 95%: 0.43-0.86), con una sensibilidad del 63% y una especificidad del 67% (p > 0.05). CONCLUSIONES: La lipasa muestra correlación con la presencia y la gravedad de la PPCPRE. La amilasa muestra correlación no significativa con la PPCPRE.

ABSTRACT Introduction: Endoscopic removal of common bile duct stones has a high success rate ranging from 85% to 95%. Bile duct stones >15 mm are difficult and frequently require lithotripsy. Peroral cholangioscopy (POC) allows lithotripsy with similar success rates. Aim: To determine the efficacy and safety of cholangioscopy-guided lithotripsy used in the treatment of difficult to remove bile duct stones vs. conventional therapy. Methods: Search was based in Medline, Embase, Cochrane Central, Lilacs/Bireme. Studies enrolling patients referred for the removal of difficult bile duct stones via POC were considered eligible. Two analyses were carried out separately, one included randomized controlled trials (RCTs) and another observational studies. Results: Forty-six studies were selected (3 RTC and 43 observational). In the analysis there was no statistical significant difference between successful endoscopic clearance (RD=-0.02 CI: -0.17, 0.12/I²=0%), mean fluoroscopy time (MD=-0.14 CI -1.60, 1.32/I²=21%) and adverse events rates (RD=-0.06 CI: -0.14, 0.02/I²=0%), by contrast, the mean procedure time favored conventional therapy with statistical significance (MD=27.89 CI: 16.68, 39.10/I²=0%). In observational studies, the successful endoscopic clearance rate was 88.29% (CI95: 86.9%-90.7%), the first session successful endoscopic clearance rate was 72.7 % (CI95: 69.9%-75.3%), the mean procedure time was 47.50±6 min for session and the number of sessions to clear bile duct was 1.5±0.18. The adverse event rate was 8.7% (CI95: 7%-10.9%). Conclusions: For complex common bile duct stones, cholangioscopy-guided lithotripsy has a success rate that is similar to traditional ERCP techniques in terms of therapeutic success, adverse event rate and means fluoroscopy time. Conventional ERCP methods have a shorter mean procedure time.
RESUMO Introdução: A remoção endoscópica das litíases do ducto biliar comum tem alta taxa de sucesso variando de 85% a 95%. Litíases do ducto biliar >15 mm são difíceis e frequentemente requerem litotripsia. A colangioscopia peroral permite litotripsia com taxas de sucesso semelhantes. Objetivo: Determinar a eficácia e segurança da litotripsia guiada por colangioscopia no tratamento de litíases biliares difíceis em comparação à terapias convencionais guiadas por colangiopancreatografia retrógrada endoscópica. Método: Pesquisa na Medline, Embase, Cochrane Central, Lilacs/Bireme de estudos avaliando a eficácia da colangioscopia na remoção de cálculos biliares difíceis. Duas análises foram realizadas separadamente, uma incluiu ensaios clínicos randomizados (ECR) e outros estudos observacionais. Resultados: Quarenta e seis estudos foram selecionados (3 ECR e 43 observacionais). Na análise, não houve diferença estatisticamente significativa na taxa de extração litiásica total (RD=-0,02 IC: -0,17,0,12/I²=0%), tempo médio de fluoroscopia (MD=-0,14 CI -1,60, 1,32/I²=21%) e na taxa de eventos adversos (RD=-0,06 IC: -0,14, 0,02/I²=0%).Por outro lado, o tempo médio do procedimento favoreceu terapêuticas convencionais guiadas por CPRE com significância estatística (MD=27,89 IC: 16,68, 39,10/I²=0%). Nos estudos observacionais, a taxa do tratamento completo por endoscopia foi de 88,29% (IC95: 86,9% a 90,7%), a taxa de sucesso na primeira sessão foi de 72,7% (IC95: 69,9% a 75,3%), o tempo médio do procedimento foi de 47,50±6 min por sessão e o número de procedimentos necessários para remoção total da litíase foi de 1,5±0,18. A taxa de eventos adversos foi de 8,7% (IC95: 7% a 10,9%), com 0,5% considerado como severo. Conclusão: Para litíases biliares difíceis, a litotripsia guiada por colangioscopia tem taxa de sucesso semelhante às terapêuticas convencionais guiadas CPRE em termos de sucesso terapêutico, taxa de eventos adversos e tempo de fluoroscopia. As terapêuticas convencionais guiadas por CPRE têm tempo médio de procedimento menor.

ABSTRACT Background: Cholangiocarcinoma is an aggressive neoplasm that usually requires palliative biliary drainage. Photodynamic therapy (PDT) has been described as a successful adjunct treatment to malignant biliary obstruction. Aim: To describe the use of digital cholangioscope to help provide laser light during biliary PDT session using locally developed light source. Method: Patient receives intravenous photosensitizer 24 h before the procedure. It starts with a regular duodenoscopy. After identification of the major papilla and retrograde cannulation, the digital cholangioscope is introduced into the common bile duct. Then, the cholangioscopic examination helps to identify the neoplastic stricture. Under direct visualization lighting catheter is advanced through the cholangioscope. Repositioning is recommended every centimeter to cover all strictured area. At the end of the procedure, a final cholangioscopy assesses the bile duct for the immediate result and adverse events. Result: This procedure was applied in one 82-year-old male due to obstructive jaundice in the last two months. EUS and ERCP revealed a severe dilation of the common bile duct associated with choledocholithiasis. Besides, was revealed dilation of hepatic duct up to a well-circumscribed hypoechoic solid mass measuring 1.8x2 cm compressing the common hepatic duct. The mass was deemed unresectable and the patient was referred for palliative treatment with PDT. He remained asymptomatic for three months. He perished due to complications 15 months after the PDT session. Conclusion: Digital cholangioscopy-guided biliary PDT is feasible and seems safe and effective as an adjunct modality in the palliation of extrahepatic cholangiocarcinoma.
RESUMO Racional: Colangiocarcinoma é neoplasia agressiva que geralmente exige drenagem biliar paliativa. A terapia fotodinâmica (TFD) tem sido descrita como tratamento adjunto bem-sucedido para tratar obstrução biliar maligna. Objetivo: Descrever o emprego do colangioscópio digital para ajudar a fornecer luz de laser durante sessão de TFD biliar usando fonte de luz desenvolvida localmente. Método: Paciente recebe fotossensibilizador intravenoso 24 h antes do procedimento que começa com duodenoscopia regular. Após a identificação da papila principal e da canulação retrógrada, o colangioscópio digital é introduzido no ducto biliar comum. Em seguida, o exame colangioscópico ajuda a identificar a estenose neoplásica. Sob visualização direta, o cateter de iluminação avança através do colangioscópio. Reposicionamento é feito a cada centímetro. Ao final colangioscopia avalia o ducto biliar quanto ao resultado imediato e a eventos adversos. Resultado: Este procedimento foi aplicado em um homem de 82 anos devido à icterícia obstrutiva nos últimos dois meses. EUS e CPRE revelaram dilatação grave do ducto biliar comum associada à coledocolitíase. Além disso, havia dilatação do ducto hepático até massa sólida hipoecóica bem circunscrita, medindo 1,8x2 cm, comprimindo o ducto hepático comum. Ela foi considerada irressecável e paciente encaminhado para tratamento paliativo com TFD que permaneceu assintomático por três meses. Morreu devido a complicações 15 meses após a sessão de TFD. Conclusão: A TFD biliar guiada por colangioscopia digital é viável e parece segura e eficaz como modalidade auxiliar na paliação de colangiocarcinoma extra-hepático.

BACKGROUND: Choledocholithiasis is one of the main complications of cholelithiasis with a prevalence in the Mexican population of 14%. The management through the guide proposed by the American Society for Gastrointestinal Endoscopy (ASGE) in 2010 can support the surgeon for the timely resolution of the pathology. OBJECTIVE: To determine that the guide proposed by ASGE for the management of choledocholithiasis in patients with "high risk" reduces the complications of this pathology. METHODS: A comparative, retrospective case-control study was conducted from January 1, 2015 to December 31, 2017. We included patients who were stratified at high risk of choledocholithiasis according to the ASGE guidelines. They were divided into 2 groups: the case group (diagnosis by ASGE guidelines) was submitted directly to endoscopic retrograde cholangiopancreatography (ERCP), the second group (no ASGE) followed the protocol of performing computed tomography, magnetic cholangioresonance, and finally ERCP. RESULTS: Of 61 patients with choledocholithiasis, the following groups were compared: the appearance of cholangitis, the complications after ERCP, time of ERCP, days of hospital stay and mortality. Obtaining significant difference in: "complications post ERCP" group ASGE 3/35 (9%), group no ASGE 8/26 (30.7%) with OR of 0.2 (0.05 - 0.9 IC 95%) and a p = 0.03; "Cholangitis" group ASGE 2/35 (5.7%), group no ASGE 8/26 (30-7%) with ORP 0.13 (0.03-0.71 IC 95%) and p = 0.009. CONCLUSION: In our setting, the use of the ASGE guideline reduces the presence of cholangitis and post-ERCP complications.
ANTECEDENTES: La coledocolitiasis es una de las principales complicaciones de la colelitiasis, con una prevalencia en la población mexicana del 14%. El manejo a través de la guía propuesta por la American Society for Gastrointestinal Endoscopy (ASGE) en 2010 puede apoyar al cirujano para la resolución oportuna de la patología. OBJETIVO: Determinar que el uso de la guía de la ASGE para el manejo de coledocolitiasis en pacientes con «alto riesgo¼ reduce las complicaciones de esta patología. MÉTODO: Estudio comparativo, retrospectivo, de casos y controles, del 1 de enero de 2015 al 31 de diciembre de 2017. Se incluyeron pacientes que se estratificaron en alto riesgo de coledocolitiasis de acuerdo con la guía ASGE y se dividieron en dos grupos: el grupo de casos (diagnóstico por guía ASGE) fue sometido directamente a colangiopancreatografía retrógrada endoscópica (CPRE), y el otro grupo (no ASGE) siguió el protocolo de realizar tomografía computarizada, colangiorresonancia magnética y finalmente CPRE. RESULTADOS: De 61 pacientes con coledocolitiasis, se comparó entre los grupos la aparición de colangitis, las complicaciones posteriores a la CPRE, el tiempo de realización de la CPRE, los días de estancia hospitalaria y la mortalidad. Se obtuvo diferencia significativa en complicaciones tras la CPRE (grupo ASGE 3/35 [9%], grupo no ASGE 8/26 [30.7%]; odds ratio [OR]: 0.2; intervalo de confianza del 95% [IC 95%]: 0.05-0.9; p = 0.03) y en colangitis (grupo ASGE 2/35 [5.7%], grupo no ASGE 8/26 [30-7%]; OR: 0.13; IC 95%: 0.03-0.71; p = 0.009). CONCLUSIÓN: En nuestro medio, el empleo de la guía ASGE reduce la presencia de colangitis y las complicaciones tras la CPRE.

INTRODUCCIÓN: Los carcinomas adenoneuroendocrinos mixtos (MANEC) son tipos de tumores bifásicos, reconocidos morfológicamente ante la presencia de una formación neoplásica constituida de manera simultánea por epitelio glandular y células neuroendocrinas. Dentro del tracto gastrointestinal, estas neoplasias predominan en el estómago o el colon. Solo 19 casos localizados en la ampolla de Vater han sido reportados por la literatura. OBJETIVO: Reportar un caso de MANEC; revisar la epidemiología, pronóstico y tratamiento de estos tumores. MATERIALES Y MÉTODO: Presentación de caso clínico de una paciente con diagnóstico de adenocarcinoma neuroendocrino mixto de la región ampular. DISCUSIÓN: La presentación clínica, el manejo y el pronóstico son similares al del adenocarcinoma ampular. Se diagnostican con el examen histopatológico de la muestra resecada. Ambos componentes deben ser histológicamente malignos, y cada uno de ellos debe representar al menos el 30% de la lesión. CONCLUSIÓN: Los MANEC ampulares son tumores poco comunes a nivel mundial, siendo éste el primer caso reportado en nuestro instituto.
INTRODUCTION: Mixed adenoneuroendocrine carcinomas (MANEC) are types of biphasic tumors, morphologically recognized in the presence of a neoplastic formation constituted simultaneously by glandular epithelium and neuroendocrine cells. Only 19 cases located in the ampulla of Vater have been reported in the literature. Within the gastrointestinal tract, these neoplasms predominate in the stomach or colon. AIM: Report a case of MANEC; review of the epidemiology, prognosis and treatment of these tumors. MATERIALS AND METHOD: Case presentation of a patient diagnosed with mixed adeno-neuroendocrine carcinoma of the ampullary region. DISCUSSION: The clinical presentation, management and prognosis are similar to ampullary adenocarcinoma. These tumors are diagnosed with a histopathological examination of the resected specimen. Both components must be histologically malignant, and each of them must represent at least 30% of the lesion. CONCLUSION: MANEC of the ampulla are rare tumors worldwide, being this case the first reported in our institute.

Resumen La ictericia obstructiva es una causa frecuente de consulta en los servicios de urgencias. El síndrome de Lemmel se describe como un síndrome biliar obstructivo secundario a un divertículo duodenal perpipapilar en el que se han descartado otras causas de ictericia obstructiva. Se describe un caso de ictericia obstructiva en una paciente de 84 años, en la que se realiza resonancia magnética y endosonografía biliopancreática que descartan litiasis biliar; posteriormente, es llevada a colangiopancreatografía retrógrada endoscópica (CPRE), en la que se evidencia divertículo peripapilar sin coledocolitiasis, y se realiza papilotomía, luego de la cual la paciente presenta una evolución clínica favorable.
Abstract Obstructive jaundice is a frequent for patients to come to emergency services. Lemmel's syndrome is an obstructive biliary syndrome secondary to a papillary duodenal diverticulum for which other causes of obstructive jaundice have been ruled out. We describe a case of obstructive jaundice in an 84-year-old patient who underwent magnetic resonance imaging and biliopancreatic endosonography to rule out biliary lithiasis. Subsequently, the patient underwent ERCP where the papillary diverticulum was evident and without choledocholithiasis. A papillotomy was performed. Afterwards, the patient's clinical evolution was favorable.
