RESUMO

RESUMEN Antecedentes: la duodenopancreatectomía cefálica (DPC) con resección vascular venosa está indicada para el tratamiento del adenocarcinoma ductal y de tumores neuroendocrinos de páncreas, tanto por laparoscopia como por laparotomía. Objetivo: describir los resultados de una serie de pacientes operados de DPC con resección vascular venosa y comparar la morbimortalidad entre los abordados por laparoscopia y por laparotomía. Material y métodos: se realizó un estudio observacional, comparativo, retrospectivo de pacientes con DPC con resección vascular entre enero de 2022 y agosto de 2023. El abordaje laparoscópico fue determinado en menores de 80 años, invasión venosa tumoral igual a 180° o menor en la tomografía, buen performance status, y no haber realizado tratamiento neoadyuvante. Resultados: fueron realizadas 23 DPC con resección vascular venosa: 11 por laparoscopia y 12 por laparotomía. Las 11 realizadas por laparoscopia fueron resecciones laterales, y, en los 12 abordados por laparotomía, se realizó resección total de vena porta en 5 y en el resto, resección lateral. El tiempo de "clampeo" (pinzamiento) portal y la necesidad de transfusiones fue similar en ambos grupos. El estudio patológico reveló R0 en el 78,2% de los pacientes e invasión venosa en el 40.9%. La morbilidad con laparoscopia y con laparotomía consistió, respectivamente, en: fístula pancreática en 7 (4 y 3), vaciamiento gástrico retardado en 4 (1 y 4), fístula biliar en uno (1 y 0), neumonía en dos (1 y 1) e infección de herida en uno (0 y 1). La mortalidad fue de 8,6% por el fallecimiento de dos pacientes, uno en cada grupo. Conclusión: de acuerdo con los criterios empleados, la morbimortalidad de la DPC con resección vascular fue similar por laparoscopia y por laparotomía.

ABSTRACT Background: Cephalic pancreaticoduodenectomy (CPD) with venous resection is indicated for the treatment of ductal adenocarcinoma and neuroendocrine tumors of the pancreas, either through laparoscopy or laparotomy. Objective: The aim of this study was to describe the results of a series of patients undergoing CPD with venous vascular resection and compare morbidity and mortality between the laparoscopic approach and open surgery. Material and methods: We conducted a retrospective, comparative and observational study of patients who underwent CPD with venous vascular resection between January 2022 and July 2023. Criteria for laparoscopic surgery were age < 80 years, interface between tumor and vein of 180° of the circumference of the vessel wall or less on computed tomography, good performance status, and no previous neoadjuvant treatment. Results: A total of 23 CPD procedures with venous vascular resection were performed: 11 by laparoscopy and 12 by laparotomy. The 11 laparoscopic procedures were lateral resections, and in the 12 patients approached by laparotomy, 5 were total portal vein resections and 7 were lateral resections. Portal vein clamping time and need for transfusion was similar in both groups. The pathological examination reported R0 resections in 78.2% and venous invasion in 40.9%. The complications associated with laparoscopy and laparotomy were pancreatic fistula in 4 and 3 patients, respectively, delayed gastric emptying in 1 and 4 patients, respectively, biliary fistula in 1 and 0 patients, respectively, aspiration pneumonia i 1 and 1 patients, respectively and surgical site infection in 0 and 1 patients, respectively. Mortality was 8.6% (n =2), one in each group. Conclusion: According to the criteria used, the morbidity and mortality of CPD with vascular resection were similar for laparoscopy and laparotomy.

RESUMO

RESUMEN El insulinoma es un tumor pancreático poco frecuente con una incidencia del 0,4%, generalmente benigno. Se presenta más frecuentemente en mujeres con una relación 2:1. Es el tumor neuroendocrino funcionante más común del páncreas1, responsable del 70 al 75% de hiperinsulinemía en la práctica clínica. El diagnóstico suele representar un desafío, y el retraso diagnóstico poner en riesgo la vida del paciente. El tratamiento quirúrgico es curativo en más del 90% de los casos; la táctica conservadora, siempre que sea posible, es la de elección. Informamos acerca de una duodenopancreatectomía cefálica (DPC) por insulinoma en un paciente de sexo masculino, con mala interpretación diagnóstica previa de enfermedad neuropsiquiátrica y tratado con anticonvulsivantes.

ABSTRACT Insulinomas are rare pancreatic tumors usually benign with an incidence of 0.4%. They are more common in women with a female-to-male ratio of 2:1. It is the most common functioning neuroendocrine tumor of the pancreas and is responsible for 70-75% of hyperinsulinemia in clinical practice1. The diagnosis is often a challenge, and a delay in diagnosis can have serious consequences for the patient. Surgical treatment is curative in more than 90% of cases, and the conservative approach is the treatment of choice whenever possible. We report the case of a cephalic pancreaticoduodenectomy (CPD) due to an insulinoma in a male patient with a previous misdiagnosis of a neuropsychiatric disorder treated with anticonvulsants.

RESUMO

Objetivo: realizar una revisión bibliográfica y presentación de caso de colangiocarcinoma tubulopapilar. Material y Método: Se revisó la ficha médica y las características clínicas, radiológicas y patológicas del tumor, y la literatura científica respecto al carcinoma tubulopapilar. Caso Clínico: Paciente con ictericia progresiva asociado a baja de peso. El estudio imagenológico muestra amputación del tercio distal del colédoco por tejido de partes blandas, sugerente de colangiocarcinoma. Se realiza endosonografía, arrojando "fragmentos superficiales de adenocarcinoma tubulopapilar". Se realiza duodenopancreatectomía cefálica y, posteriormente, se inicia quimioterapia. Discusión: El colangiocarcinoma es una neoplasia de la vía biliar. Existen diferentes variantes histológicas, entre ellas el colangiocarcinoma tubulopapilar. Su diagnóstico se basa en estudios imagenológicos y anatomopatológicos. El principal hallazgo imagenológico va a depender del patrón de crecimiento tumoral; masiforme, periductal o intraductal. Dentro de los intraductales, se describe un carcinoma biliar con crecimiento tubulopapilar, con fenotipo pancreatobiliar epitelial. En los últimos años han sido de interés por tener mejor pronóstico. Conclusión: El colangiocarcinoma tubulopapilar es una variante histológica poco frecuente del colangiocarcinoma, que se asocia a un mejor pronóstico que otras variantes.

Objective: To conduct a literature review and present a case study of tubulopapillary cholangiocarcinoma. Material and Method: The clinical record and the clinical, radiological, and pathological characteristics of the tumor were reviewed, along with the scientific literature regarding tubulopapillary carcinoma. Case Report: Patient with progressive jaundice associated with weight loss. Imaging studies show amputation of the distal third of the common bile duct by soft tissue, suggestive of cholangiocarcinoma. Endosonography was performed, yielding "superficial fragments of tubulopapillary adenocarcinoma." Subsequently, a cephalic duodenopancreatectomy is performed, followed by chemotherapy. Discussion: Cholangiocarcinoma is a neoplasm of the biliary tract. There are different histological variants, including tubulopapillary cholangiocarcinoma. Its diagnosis is based on imaging and pathological studies. The main imaging finding will depend on the pattern of tumor growth: mass-forming, periductal, or intraductal. Among the intraductal types, a biliary carcinoma with tubulopapillary growth and an epithelial pancreatobiliary phenotype has been described. In recent years, they have been of interest due to their better prognosis. Conclusion: Tubulopapillary cholangiocarcinoma is a rare histological variant of cholangiocarcinoma that is associated with a better prognosis than other variants.

RESUMO

RESUMEN Introducción: La cirugía de Whipple, también conocida como duodenopancreatectomía cefálica (DPC), es un procedimiento muy usado para varios tipos de cáncer peri ampular. Objetivos: Establecer los factores asociados a la evolución con complicaciones post DPC en el Servicio de Cirugía de Páncreas del Hospital Nacional Edgardo Rebagliati Martins en Lima, Perú. Métodos: Se realizó un estudio observacional, cuantitativo, analítico, transversal y retrospectivo en 81 pacientes durante el período comprendido entre enero de 2017 hasta diciembre de 2019, quienes fueron sometidos a una DPC. La variable dependiente fueron las complicaciones postquirúrgicas y las independientes fueron indicadores preoperatorios, perioperatorios y post operatorios. Se revisaron las historias clínicas. Se realizó regresión logística para hallar los OR crudos y ajustados. Resultados: La media de la edad fue 65,97±10,14 y el sexo más frecuente fue el masculino. La complicación más frecuente fue la fístula pancreática (34,6%). Los factores asociados a complicaciones post DPC fueron el sexo masculino (ORa: 4,46, IC95%: 1,35-14,77), ampuloma (ORa: 6,92, IC95%: 1,75-27,48) y la consistencia blanda del páncreas (ORa: 4,52, IC95%: 0,07-0,58). Conclusiones: Los factores asociados a complicaciones en la evolución post DPC fueron el sexo masculino, el ampuloma, y la consistencia blanda del páncreas.

ABSTRACT Introduction: Whipple procedure, also known as pancreatoduodenectomy (PD), is a widely used procedure for several types of peri-ampullary cancer. Objectives: To establish the factors associated with postoperative complications after PD in the Pancreas Surgery Service of the Edgardo Rebagliati Martins National Hospital in Lima, Peru. Methods: An observational, quantitative, analytical, cross-sectional, and retrospective study was carried out on 81 patients during the period from January 2017 to December 2019, who underwent PD. The dependent variable was postoperative complications and the independent variables were preoperative, perioperative, and postoperative variables. The medical records were reviewed. Logistic regression was performed to find the crude and adjusted ORs. Results: The mean age was 65.97±10.14 and the majority of patients were male. The most common postoperative complication was pancreatic fistula (34.6%). Factors associated with postoperative complications after PD were male sex (aOR: 4.46, 95% CI: 1.35-14.77), ampullary cancer (aOR: 6.92, 95% CI: 1.75-27.48), and soft consistency of the pancreas (aOR: 4.52, 95% CI: 0.07-0.58). Conclusions: The factors associated with postoperative complications after PD were male sex, ampulloma, and soft consistency of the pancreas.

RESUMO

RESUMEN El tumor sólido pseudopapilar de páncreas (TSP) es un tumor infrecuente, de bajo grado de malignidad, que representa el 1-3% de todas las neoplasias pancreáticas, con predilección por el sexo femenino, y es el tumor sólido de páncreas más frecuente en la infancia. Mujer de 13 años que consultó por dolor abdominal de 5 días de evolución, en hipocondrio derecho e irradiado a espalda, con náuseas y vómitos. TSP es diagnosticado con ecografía, tomografía computarizada (TC) y resonancia magnética (RM). Se realizó duodenopancreatectomía cefálica. La paciente fue dada de alta. El examen anatomopatológico informó un TSP de páncreas. El abordaje quirúrgico de estos tumores, abierto o laparoscópico, permite una excelente supervivencia alejada.

ABSTRACT Solid pseudopapillary tumor (SPT) of the pancreas is a rare neoplasm with a low malignant potential and represents 1- 3% of all pancreatic tumors. They usually occur in women and are the most common solid pancreatic tumor in children. A 13-year-old girl visited the emergency department due to abdominal pain in the right hypochondrium radiating to the back, nausea and vomiting lasting 5 days. A SPT was diagnosed by ultrasound, computed tomography (CT) scan and magnetic resonance imaging (MRI). The patient underwent cephalic pancreaticoduodenectomy and was discharged. The pathological study reported a SPT of the pancreas. The surgical approach of these tumors through open surgery or laparoscopy offers excellent long-term survival.

RESUMO

Introducción: La duodenopancreatectomía cefálica es una operación cada vez más frecuente en pacientes seleccionados. Objetivo: Identificar la morbilidad y la mortalidad concerniente a la duodenopancreatectomía cefálica convencional. Métodos: Se realizó un estudio observacional, descriptivo de una serie de 15 casos operados de duodenopancreatectomía cefálica. Se investigaron las variables: estadificación según clasificación tumor, linfonódulo, metástasis (TNM), diagnóstico anatomopatológico, complicaciones, tiempo quirúrgico y estado al egreso. Se utilizaron el número absoluto y el porcentaje como medidas de resumen para las variables estadificación y diagnóstico; la media, la mediana y el rango para el tiempo quirúrgico y el intervalo de confianza para el estado al egreso. Resultados: El diagnóstico anatomopatológico principal fue adenocarcinoma de páncreas con 9 pacientes (60,1 %) y de duodeno con 2 (13,3 %). El estadio posoperatorio IIA fue el que prevaleció con 5 (45,5 %). El retraso del vaciamiento gástrico fue la complicación quirúrgica que prevaleció, con 7 (46,7 %) enfermos, seguida de la fístula biliar con 3 (20,0 %). La fístula pancreática, la lesión de la vena mesentérica superior y la hemorragia posoperatoria se presentaron una sola vez (6,7 %), respectivamente. Estas 2 últimas, provocaron la muerte del enfermo en las primeras 48 horas del posoperatorio. Fallecieron 4 (26,7 %) pacientes de la serie. Conclusiones: Las complicaciones posquirúrgicas se observan principalmente a expensas del retardo del vaciamiento gástrico, la fístula biliar y pancreática. La mortalidad puede estar relacionada con la prolongación del tiempo quirúrgico igual o mayor de 5 horas, con el consiguiente aumento de las pérdidas hemáticas.

Introduction: Cephalic duodenopancreatectomy is an increasingly frequent operation in selected patients. Objective: To identify the morbidity and mortality related to conventional cephalic duodenopancreatectomy. Methods: An observational, descriptive study of a series of 15 cases operated on cephalic duodenopancreatectomy. The variables were investigated: staging according to the Tumor, Linphonod, Metastasis (TNM) classification, pathological diagnosis, complications, surgical time and discharge status. Absolute number and percentage were used as summary measures for the variables staging and diagnosis; mean, median and range for surgical time and confidence interval for discharge status. Results: The main pathological diagnosis was adenocarcinoma of the pancreas with 9 patients (60.1%) and of the duodenum with 2 (13.3%). Postoperative stage IIA was the one that prevailed with 5 (45.5%) patients. Delayed gastric emptying was the prevailing surgical complication, with 7 (46.7%) patients, followed by biliary fistula with 3 (20.0%). Pancreatic fistula, superior mesenteric vein injury, and postoperative hemorrhage occurred only once (6.7%), respectively. These last 2, caused the death of the patient in the first 48 hours of the postoperative period. Four (26.7%) patients in the series died. Conclusions: Postoperative complications are mainly observed at the expense of delayed gastric emptying and biliary and pancreatic fistula. Mortality may be related to the prolongation of surgical time equal to or greater than 5 hours with the consequent increase of blood loss.

RESUMO

ABSTRACT BACKGROUND: Lipomatous pseudohypertrophy of the pancreas, pancreatic lipomatosis, pancreatic steatosis, non-alcoholic fatty pancreatic disease, or fatty pancreas is an extremely rare disease, characterized by the organ enlargement and a localized or diffuse replacement of pancreatic acinar cells by mature adipose tissue, preserving the pancreatic ductal system and islets of Langerhans. AIMS: To report a rare case of lipomatous pseudohypertrophy of the pancreas in a symptomatic patient and the surgical treatment employed. METHODS: A 24-year-old male patient with weight loss (10 kilograms in 8 months), hyperglycemia, severe and recurrent acute abdominal pain, epigastric discomfort associated with nausea, vomiting, and jaundice for 40 days. Magnetic resonance imaging was performed, revealing an irregular lipomatous pseudohypertrophy of the pancreas, measuring 6.0 × 5.6 cm in the head, uncinate process, and part of the body of the pancreas. The pancreatic duct dilation was diffuse and irregular, associated with atrophy of the remnant parenchyma, particularly in the tail of the pancreas. The patient underwent pancreatoduodenectomy without total mesopancreas excision followed by pancreatojejunostomy. RESULTS: The postoperative course was uneventful, the length of stay in the ICU was two days, and the patient was discharged on the seventh postoperative day. CONCLUSIONS: The disease treatment depends on the signs and symptoms at presentation and a pancreatoduodenectomy is indicated in patients with severe and recurrent abdominal pain.

RESUMO RACIONAL: Pseudo-hipertrofia lipomatosa do pâncreas, lipomatose pancreática, esteatose pancreática, doença pancreática gordurosa não alcoólica ou pâncreas gorduroso é uma doença extremamente rara, caracterizada por aumento do órgão e substituição localizada ou difusa de células acinares pancreáticas por tecido adiposo, preservando o sistema ductal pancreático e as ilhotas de Langerhans. OBJETIVOS: Relatar um caso raro de pseudo-hipertrofia lipomatosa do pâncreas, em paciente sintomático e o tratamento cirúrgico empregado. MÉTODOS: Paciente do sexo masculino, 24 anos, com queixas de emagrecimento (10 quilos nos últimos 8 meses), hiperglicemia, dor abdominal aguda intensa e recorrente, desconforto epigástrico associado a náuseas, vômitos e icterícia há 40 dias. A ressonância magnética (RM) revelou pseudo-hipertrofia lipomatosa irregular do pâncreas, medindo 6,0 × 5,6 cm na cabeça, processo uncinado e parte do corpo do pâncreas. A dilatação do ducto pancreático era difusa e irregular, associada à atrofia do parênquima remanescente, principalmente na cauda do pâncreas. O paciente foi submetido à duodenopancreatectomia sem excisão total do mesopâncreas seguida de pancreatojejunostomia. RESULTADOS: O pós-operatório transcorreu sem intercorrências, o tempo de internação na UTI foi de 2 dias, com alta hospitalar no sétimo dia. CONCLUSÕES: O tratamento da doença depende dos sinais e sintomas na apresentação e a duodenopancreatectomia é indicada em pacientes com dor abdominal intensa e recorrente.

RESUMO

El adenocarcinoma pancreático ductal (APD) es la cuarta causa de muerte por cáncer y se proyecta que para el 2030 ocupe el segundo lugar. El pronóstico es sombrío, siendo la sobrevida menor a 9% en 5 años. Se consideró durante mucho tiempo a la resección quirúrgica como el único tratamiento curativo, sin embargo, sólo el 15 a 20% de los pacientes pueden ser beneficiados con la misma. La clasificación pre terapéutica más utilizada es la del National Comprehensive Cáncer Network (NCCN), basada en la relación del tumor con estructuras vasculares, clasificándolos en tumores "resecables", de resección límite "Borderlines" y "localmente avanzados". Se presenta el primer caso registrado en Paraguay de APD con infiltración de la Vena Mesentérica Superior (VMS) tratado con duodenopancreatectomía cefálica (DPC) asociada a resección vascular mayor.

Pancreatic ductal adenocarcinoma (PDA) is the fourth leading cause of cancer death and is projected to rank second by 2030. The prognosis is bleak, with survival being less than 9% in 5 years. For a long time, surgical resection was considered the only curative treatment, however, only 15 to 20% of patients can benefit from it. The most widely used pre-therapeutic classification is that of the National Comprehensive Cancer Network (NCCN), based on the relationship of the tumor with vascular structures, classifying them into "resectable", "borderline" and "locally advanced" tumors. We present the first registered case in Paraguay of PDA with infiltration of the Superior Mesenteric Vein (SMV) treated with cephalic duodenopancreatectomy (CPD) associated with major vascular resection.

RESUMO

Solid pseudopapillary tumor of the pancreas is a rare entity, more frequent in women between the 2nd and 4th decades. The diagnosis is usually incidental and it can be reached by computed tomography or magnetic resonance imaging. Subsequent pathological confirmation is necessary for an adequate treatment. A retrospective study of six cases was carried out. All the patients were female, between 14 and 56 years of age, in which 50% the tumor were an incidental finding. We had three cases located in the head and three in the body of the pancreas. We performed three pancreaticoduodenectomies and three distal pancreatectomies with splenic preservation, without disease recurrence.

El tumor sólido-quístico de páncreas es poco frecuente y predomina en mujeres entre la segunda y la cuarta décadas de la vida. Los pacientes son generalmente asintomáticos. El diagnóstico se realiza por imágenes con tomografía o resonancia magnética, y con la posterior confirmación patológica para poder ofrecer un tratamiento adecuado. Presentamos una serie de seis casos. Todas las pacientes fueron de sexo femenino, de entre 14 y 56 años. El 50% fueron un hallazgo incidental. Tuvimos tres casos localizados en la cabeza y tres en el cuerpo del páncreas. Se realizaron tres duodenopancreatectomías cefálicas y tres pancreatectomías distales con preservación esplénica, con buena evolución y sin recidiva.

RESUMO

Antecedentes: La duodenopancreatectomía cefálica (D.P.C.) es el procedimiento quirúrgico aceptado para el tratamiento de los tumores malignos y benignos del confluente bilio-duodenopancreático. Lugar de aplicación: Hospital Nacional de Clínicas y Clínica privada. Diseño: Estudio protocolizado y prospectivo. Material y método: Entre diciembre 2000 y diciembre 2014 se operaron 96 DPC. Las indicaciones de la cirugía fueron: 39 cánceres de la cabeza de páncreas, 19 cánceres de papila, 9 cáncer de duodeno, 10 de colédoco distal, 5 tumores quísticos del páncreas, 4 pancreatitis crónica, 3 tumores funcionantes de páncreas, 3 tumores no funcionantes, finalmente 3 tumores de otra etiología. Resultados: Con respecto a la mortalidad dentro de los 30 días, fallecieron 5 pacientes (4, 80 %). Posteriormente, fallecieron dentro de los 90 días 5 pacientes más (9,3 %). En las complicaciones quirúrgicas, nosotros encontramos: la fistula pancreática hubo en 32 pacientes. Con respecto al Vaciamiento gástrico estuvo presente en 19 enfermos y finalmente en 5 pacientes tuvieron una hemorragia intra peritoneal que fueron re intervenidos y uno de los cuales falleció. Por otro lado, hubo 11 colecciones abdominales, donde se re operaron 4 pacientes y a los 7 restantes se les colocó un drenaje en dicha colección. Se re intervinieron 4 pacientes con evisceración, CONCLUSIONES: Los resultados de nuestro trabajo, apoyan el concepto que cirujanos con bajo volumen de D.P.C. anuales, pero con una estricta formación en Instituciones con infraestructura adecuada y un equipo multidisciplinario, pueden también obtener buenos resultados en las lesiones malignas y benignas del confluente bilio-duodeno-pancreático

Background: Cephalic duodenopancreatectomy (CDP) (pancreaticoduodenectomy of the head of the pancreas) is the surgical option accepted as the procedure of choice for the management of both malignant and benignant tumours of the duodenal-pancreatic biliary confluence. Setting: National Clinical Hospital and private practice. Desing: Protocoled and prospective study. Methods: Between December 2000 through December 2014, 96 CDP have been operated upon: 39 cancers of the head of the pancreas, 19 cancers of the papilla, 9 cancers of the duodenum, 10 of the distal common bile ducts, 5 cystic tumours of the pancreas, 4 chronic pancreatitis, 3 functioning pancreas, 3 non-functioning tumours, and finally 3 tumours of different ethiologies: 1 GIST of duodenum, 1 metastasis from a renal cancer, and 1 colon cancer of the hepatic flexure who invaded the duodenum. Results: Pancreatic fistulas were observed in 32 patients. With reference to gastric emptying it was present in 19 patients, and finally in 5 patients an intra peritoneal haemorrhage was present which were re- intervened, and one of them died. On the other hand, 11 abdominal collections were present, of whom 4 patients were re-operated, and to the remaining 7 ,a drainage was placed in the collection. Four patients were re-operated with evisceration. Conclusions: The results of our study support the concept that surgeons with low volume of annual CDP, but with strict training in institutions with adequate infrastructure and a multidisciplinary team, can obtain also good results.

Setting: Clinico- National Hospital and private practice. Desing: protocoled and prospective study. Methods: between december 2000 and december 2014, 96 cpd have been operated. Of these, 54 were men and 42 were women, with ages ranged between 27 to 79 years (average 59 years). The time between the onset of symptoms and the first consultation period. Averaged 81 days (range 10-129 days). All the patients were submitted to ultrasound and ct of the abdomen. Results: with reference to mortality within 30 days, 5 patients (4, 80%) died. Subsequently, 5 more patients died within 90 days (9.3%). With reference to morbidity, we divided them in two, clinicals that were 17 patients (16.32%) And 50 were surgical (48%). Within pancreatic fistula included 32 patients (30, 72%). With reference to the gastric emptying, it was present in 19 (18.24%) And finally 5 (4.80%) Had intra peritoneal bleeding. In addition, 8 patients had a biliary fistula (7.62%). Conclusions: the results of our study support the concept that surgeons with low volume of cpd annually, but with strict training in institutions with adequate infraestructure and a multidisciplinary team, can also obtain good results in the malignant and benign lesions of the biliary-duodeno-pancreatic confluence.

RESUMO

Resumen Introducción: La duodeno pancreatectomía cefálica es una operación compleja cuyos resultados a corto plazo son multifactoriales. Objetivo: Evaluar el impacto de la curva de aprendizaje en los resultados a corto plazo de la duodenopancreatectomía cefálica en un hospital de nivel II. Materiales y Método: Se analizaron los datos obtenidos a partir de una base de datos mantenida prospectivamente desde 2005. Se definieron dos periodos de tiempo: de 2005 a 2011 y de 2012 a 2017. Se compararon la morbilidad, mortalidad y estancia postoperatoria de ambos períodos. Resultados: Durante el período de tiempo estudiado se hicieron 126 duodenopancreatectomías cefálicas, 61 durante la primera etapa y 65 durante la segunda. La tasa de transfusión intraoperatoria se redujo de 33% a 15% (p = 0,011). La tasa de transfusión postoperatoria se redujo de 39 a 23% (p = 0,021). No hubo diferencias significativas con respecto a la incidencia global de complicaciones postoperatorias (59% y 52,3%). La incidencia de abscesos intraabdominales fue significativamente menor en el segundo período (18% y 4,6%, respectivamente; p = 0,038). La tasa de reintervenciones se redujo significativamente, de 22% a 9% (p = 0,049). También se redujo significativamente la tasa de mortalidad, de 6,56% a 0% (p = 0,032). La estancia media postoperatoria disminuyó significativamente en el segundo período, pasando de 19,6 a 15,8 días (p = 0,001), con una mayor proporción de pacientes dados de alta en los 8 primeros días de postoperatorio (11,5% y 38,5%, respectivamente; p = 0,001). Conclusión: La curva de aprendizaje es un factor que permite mejorar los resultados de la duodenopancreatectomía cefálica, en un hospital de nivel II, hasta alcanzar valores similares a los de un hospital de nivel III.

Introduction: The duodenum pancreatectomy cephalic is a complex operation whose short-term results are multifactorial. Aim: To assess the impact of the learning curve on the short-term outcomes of cephalic duodenopancreatectomy at a level II hospital. Materials Method: We analyze the data obtained from a database maintained prospectively since 2005. Two time periods were defined: from 2005 to 2011 and from 2012 to 2017. The morbidity, mortality and postoperative stay of both periods were compared. Results: 126 cephalic duodenopancreatectomies were performed, 61 during the first period and 65 during the second. The intraoperative transfusion rate was reduced from 33% to 15% (p = 0.011). The postoperative transfusion rate was reduced from 39 to 23% (p = 0.021). There were no significant differences with respect to the overall incidence of postoperative complications (59% and 52.3%, respectively). However, the incidence of intra-abdominal abscesses was significantly lower in the second period (18% and 4.6%, respectively, p = 0.038). The rate of reoperations was significantly reduced, from 22% to 9% (p = 0.049). The mortality rate was also significantly reduced, from 6.56% to 0% (p = 0.032). The mean postoperative stay decreased significantly in the second period, from 19.6 to 15.8 days (p = 0.001), with a higher proportion of patients discharged in the first 8 postoperative days (11.5% and 38.5%, respectively, p = 0.001). Conclusion: The learning curve is a factor allows improving the results of cephalic pancreaticoduodenectomy, in a level II hospital, until reaching values similar to those of a level III hospital.

RESUMO

OBJECTIVE: To evaluate the relationship between C reactive protein and procalcitonin levels and the appearance of post-operative intraabdominal infection, in patients with pancreaticoduodenectomy due to pancreatic cancer. METHOD: A prospective observational study, including 35 patients, was made. Procalcitonin and C reactive protein were measured before surgery, as well as 24, 48 and 72 h after the surgical procedure. Patients were divided in two groups, with and without intraabdominal infection. RESULTS: Six patients (17.1%) presented post-operative intraabdominal infection. Both, procalcitonin and C reactive protein, increased in all patients after surgery, but there were no significant differences between the two groups. However, the ratio between the C reactive protein concentrations on post-operative day 3 and the concentrations on post-operative day 1 was significantly increased in the group of patients with intraabdominal infection. The predictive positive value and the predictive negative value for this ratio were 60% and 95%, respectively, for a cut-off point of 2.3. CONCLUSIONS: The ratio between C reactive protein value on post-operative day 3 and the value on post-operative day 1 is a good predictor of post-operative intraabdominal infection after pancreaticoduodenectomy.

OBJETIVO: Evaluar la relación entre los valores de proteína C reactiva y de procalcitonina y la aparición de infección intraabdominal posoperatoria en pacientes con duodenopancreatectomía por cáncer de páncreas. MÉTODO: Estudio prospectivo observacional que incluye 35 pacientes. Ambos parámetros se midieron antes de la cirugía y a las 24, 48 y 72 horas de la intervención. Los pacientes se dividieron en dos grupos: con y sin infección intraabdominal. RESULTADOS: Seis pacientes (17.1%) tuvieron infección intraabdominal. Ambos parámetros aumentaron en todos los pacientes tras la cirugía, pero no hubo diferencias significativas entre los dos grupos. Sin embargo, el cociente entre los valores de proteína C reactiva en el día 3 y los valores en el día 1 de posoperatorio era significativamente mayor en los pacientes con infección intraabdominal, con un valor predictivo positivo del 60% y un valor predictivo negativo del 95%, para un punto de corte de 2.3. CONCLUSIONES: El cociente entre las concentraciones séricas de proteína C reactiva en el tercer día y en el primer día de posoperatorio es un buen predictor de infección intraabdominal posoperatoria después de una duodenopancreatectomía.

RESUMO

Antecedentes: la duodenopancreatectomía (DPC) continúa siendo el tratamiento de elección para los tumores periampulares. Con una mortalidad de alrededor del 5% y una morbilidad que puede llegar a alrededor del 50%, la fístula pancreática es todavía la complicación preponderante. Diversos autores sostienen que la anastomosis del páncreas con el estómago tiene menor índice de fístula que cuando se realiza con el yeyuno. Objetivo: comparar la incidencia de fístula pancreática en las pancreatogastrostomías (PG) versus pancreatoyeyunostomías (PY). Evaluar algunos factores de riesgo de fístula. Material y métodos: se evaluaron 91 DPC, 43 de ellas con reconstrucción con PG y 48 con PY. Se evaluaron datos demográficos, quirúrgicos, y se comparó la incidencia de fístula entre ambos. Resultados: la incidencia global de fístula fue de 13 pacientes (14,3%), 5 de las cuales fueron de relevancia clínica. En la comparación de ambos grupos hubo diferencias en cuanto a edad y número de pacientes con Wirsung < 3 mm, el resto de los parámetros fue similar. No hubo diferencias entre ambos grupos con respecto a la cantidad de fístulas (p: 0,478). Respecto de la evaluación de factores predisponentes para fístula, tan solo un diámetro del Wirsung < 3 mm fue significativo. Conclusión: en nuestra serie y al igual que en otras no hubo diferencias en cuanto a fístulas pancreáticas entre PG y PY, lo que nos permite inferir que la adopción y confección sistemática de una ellas obtendrá los mejores resultados.

Background: Pancreaticoduodenectomy is still the treatment of choice in patients with periampullary tumors. Pancreatic fistula is the most common complication with a mortality rate of 5% and 50% of morbidity. Some authors state that the anastomosis of the pancreas with the stomach would decrease the incidence of pancreatic fistula when compared with pancreaticojejunostomy. Objective: The aim of this study was to compare the incidence of pancreatic fistula after pacreaticogastrostomy (PG) versus pancreaticojejunostomy (PJ) and analyze the risk factors associated with the development of fistula. Material and methods: 91 patients undergoing pancreaticoduodenectomy were evaluated; 43 with PG reconstruction and 48 with PJ reconstruction. Demographic and surgical data were evaluated and the incidence of pancreatic fistula with both techniques was compared Results: The incidence of fistula for the total series was 14.3% (n = 13) and 5 were clinically relevant. There were differences in age and pancreatic duct diameter < 3 mm between the groups. The incidence of fistula was similar in both groups (p = 0.478). Pancreatic duct diameter < 3 mm was the only significant predisposing factor for the development of fistula. Conclusion: In our series, and in coincidence with others, there were no differences in the incidence of pancreatic fistulas between PG and PJ. Practicing and mastering a repetitive, standardized technique would yield the best results.

RESUMO

ABSTRACT Background: Solid pseudopapillary tumor of the pancreas is a rare low-grade malignant neoplasm. Most patients present with nonspecific symptoms until the tumor becomes large. Complete surgical resection by pancreatoduodenectomy is the treatment of choice for tumors located in the head of the pancreas Aim: To analyzed the clinicopathologic features, management, and outcomes of patients who had solid pseudopapillary tumor of the head pancreas and underwent surgical resection. Methods: Were analyzed 16 patients who underwent pancreatoduodenectomy for this condition. Results: Mean age was 25.7 years old, and 15 patients were female (93.7%). Nonspecific abdominal pain was present in 14 (87.5%). All underwent computed tomography and/or magnetic resonance imaging as part of diagnostic workup. The median diameter of the tumor was 6.28 cm, and surgical resection was performed with open or laparoscopic pancreatoduodenectomy without neoadjuvant chemotherapy. Postoperative complications occurred in six patients (37.5%) and included pancreatic fistula without mortality. The mean of hospital stay was 10.3 days. Median follow-up was 3.6 years, and no patient had local recurrence or metastatic disease. Conclusion: For these patients surgical resection with pancreatoduodenectomy is the treatment of choice showing low morbidity, no mortality, and good long-term survival.

RESUMO Racional: Tumor sólido pseudopapilar do pâncreas é neoplasia maligna rara, de baixo grau de malignidade. A maioria dos pacientes apresenta sintomas inespecíficos até que o tumor aumente de tamanho. A ressecção cirúrgica completa através a duodenopancreatectomia é o tratamento de escolha para os localizados na cabeça do pâncreas. Objetivo: Analisar as características clinicopatológicas, tratamento e resultados de pacientes com tumor sólido pseudopapilar do pâncreas localizado na cabeça do pâncreas submetidos à ressecção cirúrgica.

RESUMO

ABSTRACT Background : Pancreatic fistula is a major cause of morbidity and mortality after pancreatoduodenectomy. To prevent this complication, many technical procedures have been described. Aim: To present a novel technique based on slight modifications of the original Heidelberg technique, as new pancreatojejunostomy technique for reconstruction of pancreatic stump after pancreatoduodenectomy and present initial results. Method: The technique was used for patients with soft or hard pancreas and with duct size smaller or larger than 3 mm. The stitches are performed with 5-0 double needle prolene at the 2 o'clock, 4 o'clock, 6 o'clock, 8 o'clock, 10 o'clock, and 12 o'clock, positions, full thickness of the parenchyma. A running suture is performed with 4-0 single needle prolene on the posterior and anterior aspect the pancreatic parenchyma with the jejunal seromuscular layer. A plastic stent, 20 cm long, is inserted into the pancreatic duct and extended into the jejunal lumen. Two previously placed hemostatic sutures on the superior and inferior edges of the remnant pancreatic stump are passed in the jejunal seromuscular layer and tied. Results : Seventeen patients underwent pancreatojejunostomy after pancreatoduodenectomy for different causes. None developed grade B or C pancreatic fistula. Biochemical leak according to the new definition (International Study Group on Pancreatic Surgery) was observed in four patients (23.5%). No mortality was observed. Conclusion : Early results of this technique confirm that it is simple, reliable, easy to perform, and easy to learn. This technique is useful to reduce the incidence of pancreatic fistula after pancreatoduodenectomy.

RESUMO Racional: Fístula pancreática é a principal causa de morbidade e mortalidade após duodenopancreatectomia. Muitos procedimentos técnicos têm sido descritos para prevenir esta complicação. Objetivo: Apresentar uma nova técnica baseada em pequenas modificações sobre a técnica original de Heidelberg para pancreatojejunostomia na reconstrução do coto pancreático após duodenopancreatectomia e apresentar os resultados iniciais. Método: Esta técnica foi utilizada para pacientes com pancreas de consistência firme ou amolecida e ducto pancreático maior ou menor que 3 mm. Os pontos são realizados com prolene 5-0, duas agulhas nas posições de 2, 4, 6, 8, 10 e 12 h, com espessura total no parênquima pancreático. Uma sutura continua é realizada com prolene 4-0 de agulha única na parede posterior e anterior do pâncreas com a camada seromuscular do jejuno. Uma sonda de silicone de 20 cm de comprimento é inserida no ducto pancreático em direção ao jejuno. As duas suturas hemostáticas previamente colocadas nas bordas superior e inferior do remanescente pancreático são passadas e amarradas com a camada seromuscular do jejuno. Resultados: Dezessete pacientes foram submetidos a pancreatojejunostomia após duodenopancreatectomia por diferentes causas. Nenhum desenvolveu fístula pancreática graus B ou C. Vazamento bioquímico, de acordo com a nova definição do Grupo Internacional de Estudo em Cirurgia do Pâncreas (ISGPS), foi observado em quatro pacientes (23,5%). Não houve mortalidade. Conclusão: Os resultados iniciais desta técnica confirmam que é simples, confiável, fácil de realizar e de aprender. Ela é útil para reduzir a incidência de fistula pancreática após duodenopancreatectomia.

RESUMO

ABSTRACT Background: Pancreatoduodenectomy is a technically challenging surgical procedure with an incidence of postoperative complications ranging from 30% to 61%. The procedure requires a high level of experience, and to minimize surgery-related complications and mortality, a high-quality standard surgery is imperative. Aim: To understand the Brazilian practice patterns for pancreatoduodenectomy. Method: A questionnaire was designed to obtain an overview of the surgical practice in pancreatic cancer, specific training, and experience in pancreatoduodenectomy. The survey was sent to members who declared an interest in pancreatic surgery. Results: A total of 60 questionnaires were sent, and 52 have returned (86.7%). The Southeast had the most survey respondents, with 25 surgeons (48.0%). Only two surgeons (3.9%) performed more than 50% of their pancreatoduodenectomies by laparoscopy. A classic Whipple procedure was performed by 24 surgeons (46.2%) and a standard International Study Group on Pancreatic Surgery lymphadenectomy by 43 surgeons (82.7%). For reconstruction, pancreaticojejunostomy was performed by 49 surgeons (94.2%), single limb technique by 41(78.9%), duct-to-mucosa anastomosis by 38 (73.1%), internal trans-anastomotic stenting by 26 (50.0%), antecolic route of gastric reconstruction by 39 (75.0%), and Braun enteroenterostomy was performed by only six surgeons (11.5%). Prophylactic abdominal drainage was performed by all surgeons, and somatostatin analogues were utilized by six surgeons (11.5%). Early postoperative enteral nutrition was routine for 22 surgeons (42.3%), and 34 surgeons (65.4%) reported routine use of a nasogastric suction tube. Conclusion: Heterogeneity was observed in the pancreatoduodenectomy practice patterns of surgeons in Brazil, some of them in contrast with established evidence in the literature.

RESUMO Racional: A duodenopancreatectomia é um procedimento cirúrgico tecnicamente desafiador, com uma incidência de complicações pós-operatórias variando de 30% a 61%. O procedimento requer experiência de alto nível, e para minimizar complicações relacionadas à cirurgia uma padronização de alta qualidade é imperativa. Objetivo: Compreender o padrão da prática brasileira para duodenopancreatectomia. Método: Um questionário foi elaborado com a finalidade de obter uma visão geral da prática cirúrgica em câncer do pâncreas, treinamento específico e experiência em duodenopancreatectomia. O questionário foi enviado para cirurgiões com declarado interesse em cirurgia pancreática. Resultados: Um total de 60 questionários foi enviado e 52 retornaram (86,7%). A região sudeste foi a que mais respondeu, com 25 cirurgiões (48,0%). Apenas dois cirurgiões (3,9%), realizaram mais do que 50% das duodenopancreatectomia por videolaparoscopia. O procedimento clássico de Whipple foi realizado por 24 cirurgiões (46,2%) e a linfadenectomia padrão do Grupo Internacional de Estudo em Cirurgia Pancreática foi realizada por 43 cirurgiões (82,7%). Para a reconstrução, a pancreatojejunostomia foi realizada por 49 cirurgiões (94,2%), em alça única por 41 (78,9%), com anastomose do tipo ducto-mucosa por 38 (73,1%). O cateter transanastomose foi realizado por 26 cirurgiões (50%), reconstrução gástrica antecólica por 39 (75%) e enteroanastomose tipo Braun apenas por seis cirurgiões (11,5%). A drenagem abdominal profilática foi realizada por todos os cirurgiões e o uso de análogos da somatostatina por seis cirurgiões (11,5%). Nutrição enteral precoce no pós-operatório foi utilizada de rotina por 22 cirurgiões (42,3%) e 34 cirurgiões (65,4%), usaram sonda nasogástrica de rotina. Conclusão: Heterogeneidade foi observada na prática padrão da duodenopancreatectomia pelos cirurgiões no Brasil e, algumas delas em contraste com evidências estabelecidas na literatura.

RESUMO

O diagnóstico do paciente ictérico, por vezes, pode ser uma tarefa árdua. Dentre as causas principais, destacam-se a doença litiásica, como a coledocolitíase. Por outro lado, doenças neoplásicas como neoplasias peri-ampulares e da via biliar principal apresentam grande relevância, com destaque para o tumor de via colédoco. Apresentamos relato de caso de um paciente que apresentou dúvida diagnóstica nos exames pré-operatórios de imagem (US abdominal, TC multislice e Colangiorressonância). Realizada a abordagem através da exploração transcística das vias biliares para a confirmação do diagnóstico e posterior duodenopancreatectomia laparoscópica. Este relato ilustra a dificuldade em realizar o diagnóstico diferencial desta patologia. Mesmo com exames laboratoriais e de imagem, associados à anamnese e ao exame físico detalhado, nem sempre é possível confirmar o diagnóstico no pré-operatório, muitas vezes só confirmado durante o procedimento cirúrgico.

The diagnosis of jaundiced patient can sometimes be difficult task. Among the most important causes are common bile duct and its complications. By the other side, periampullary tumors and the main biliary duct tumor also have great relevance, especially cholangiocarcinoma. In this paper, we present the case report of patient that presented doubt diagnostic in preoperative in ultrasound, multislice CT and magnetic resonance. The patient underwent a laparoscopic trancystic common bile exploration, than decide to perform the laparoscopic pancreaticoduodenectomy. This report show the difficulty to make the diagnosis in pre operative evaluation. Even with laboratory and image, associate detailed case history and physical examination, not always is possible and confirm the diagnosis, many times the diagnostic is confirm during the surgical procedure.
