RESUMO
PURPOSE: Laparoscopic pancreatoduodenectomy (LPD) has emerged as an alternative to open technique in treating periampullary tumors. However, the safety and efficacy of LPD compared to open pancreatoduodenectomy (OPD) remain unclear. Thus, we conducted an updated meta-analysis to evaluate the efficacy and safety of LPD versus OPD in patients with periampullary tumors, with a particular focus on the pancreatic ductal adenocarcinoma patient subgroup. METHODS: According to PRISMA guidelines, we searched PubMed, Embase, and Cochrane Library in December 2023 for randomized controlled trials (RCTs) that directly compare LPD versus OPD in patients with periampullary tumors. Endpoints and sensitive analysis were conducted for short-term endpoints. All statistical analysis was performed using R software version 4.3.1 with a random-effects model. RESULTS: Five RCTs yielding 1018 patients with periampullary tumors were included, of whom 511 (50.2%) were randomized to the LPD group. Total follow-up time was 90 days. LPD was associated with a longer operation time (MD 66.75; 95% CI 26.59 to 106.92; p = 0.001; I2 = 87%; Fig. 1A), lower intraoperative blood loss (MD - 124.05; 95% CI - 178.56 to - 69.53; p < 0.001; I2 = 86%; Fig. 1B), and shorter length of stay (MD - 1.37; 95% IC - 2.31 to - 0.43; p = 0.004; I2 = 14%; Fig. 1C) as compared with OPD. In terms of 90-day mortality rates and number of lymph nodes yield, no significant differences were found between both groups. CONCLUSION: Our meta-analysis of RCTs suggests that LPD is an effective and safe alternative for patients with periampullary tumors, with lower intraoperative blood loss and shorter length of stay.

Pancreaticoduodenectomy is established as the procedure of choice for malignant tumor pathologies of the head of the pancreas or ampulla, where the patient's life prognosis is low. Complications after pancreaticoduodenectomy (e.g. pancreatic fistulas, hemorrhages, or intra-abdominal collection) are well described in the literature and are generally acute. However, there is still a small risk for late complications (e.g. pancreatitis, pancreatic insufficiency), and due to its low incidence, there has not been a consensus on the treatment. We present the case of an 18-year-old female with recurrent bouts of acute pancreatitis as a late complication of a pancreaticoduodenectomy plus pancreatojejunal anastomosis due to a pseudopapillary tumor of the pancreas. The complication was managed though surgical revision consisting of dilation and stent placement in the stenosis. The patient had an adequate postoperative evolution without further complications. Despite the advances in the surgical field, pancreaticoduodenectomy represents a highly complex surgery with high morbidity and mortality rates. The late complications of this surgery are under continuous study due to its low incidence associated with low patient survival.
RESUMO
Pancreatoduodenectomy is the most appropriate technique for the treatment of periampullary tumors. In the past, this procedure was associated with high mortality and morbidity, but with improvements in patient selection, anesthesia, and surgical technique, mortality has decreased to less than 5%. However, morbidity remains increased due to various complications such as delayed gastric emptying, bleeding, abdominal collections, and abscesses, most of which are related to the pancreatojejunostomy leak. Clinically relevant postoperative pancreatic fistula is the most dangerous and is related to other complications including mortality. The incidence of postoperative pancreatic fistula ranges from 5-30%. Various techniques have been developed to reduce the severity of pancreatic fistulas, from the use of an isolated jejunal loop for pancreatojejunostomy to binding and invagination anastomoses. Even total pancreatectomy has been considered to avoid pancreatic fistula, but the late effects of this procedure are unacceptable, especially in relatively young patients. Recent studies on the main techniques of pancreatojejunostomy concluded that duct-to-mucosa anastomosis is advisable, but no technique eliminates the risk of pancreatic fistula. The purpose of this study is to highlight technical details and tips that may reduce the severity of pancreatic fistula after pancreatojejunostomy during open or minimally invasive pancreatoduodenectomy.

BACKGROUND: Delayed gastric emptying (DGE) is a frequent complication after pancreatoduodenectomy. Preoperative factors are limited and controversial. This study aims to identify associated factors related to this complication in the Colombian population. METHODS: A retrospective review of a prospectively collected database was conducted. All patients over 18 years of age who underwent pancreaticoduodenectomy were included. Associations with DGE syndrome were evaluated with logistic regression analysis, Odds ratio, and b-coefficient were provided when appropriate. RESULTS: 205 patients were included. Male patients constituted 54.15% (n = 111). 53 patients (25.85%) were diagnosed with DGE syndrome. Smoking habit (OR 17.58 p 0.00 95% CI 7.62-40.51), hydromorphone use > 0.6 mg/daily (OR 11.04 p 0.03 95% CI 1.26-96.66), bilirubin levels > 6 mg/dL (OR 2.51 p 0.02 95% CI 1.12-5.61), and pancreatic fistula type B (OR 2.72 p 0.02 CI 1.74-10.00). DISCUSSION: Smoking history, opioid use (hydromorphone > 0.6 mg/Daily), type B pancreatic fistula, and bilirubin levels > 6 mg/dL should be considered as risk factors for DGE.

Introducción. La fístula pancreática postoperatoria es una de las complicaciones más importantes en la cirugía hepatobiliopancreática. Su diagnóstico se hace mediante la presencia de un nivel de amilasa en el líquido de drenaje al menos tres veces por encima del valor de la amilasa en suero a partir del tercer día postoperatorio. El objetivo de este estudio fue caracterizar los pacientes con fístula pancreática postoperatoria en nuestra institución, evaluando la importancia de la detección temprana y el establecimiento de un manejo oportuno. Métodos. Estudio descriptivo, retrospectivo, que incluyó los pacientes sometidos a pancreatoduodenectomía, con diagnóstico de fístula pancreática postoperatoria como complicación de cirugía hepatobiliopancreática, en el Hospital Internacional de Colombia, en Piedecuesta, entre enero del 2017 y diciembre de 2020. Se excluyeron los pacientes con otro tipo procedimiento quirúrgico y aquellos que decidieron no participar en el estudio. Resultados. Se evaluaron 69 pacientes, con un predominio del sexo femenino (n=38; 55,1 %) y mediana de la edad de 57 años. El 33,3 % (n=24) de los pacientes intervenidos desarrollaron fístula pancreática postoperatoria, siendo el 23,2 % fuga bioquímica, grado B 8,7 % y grado C 2,9 %, para quienes se indicaron manejo expectante, control ecográfico y reintervención, respectivamente. Fallecieron 5 pacientes (7,2 %). Conclusiones. La fístula pancreáticapostoperatoria es una complicación para tener en cuenta en todos los pacientes sometidos a pancreatoduodenectomía. Existen estrategias que pueden permitir disminuir la incidencia de esta complicación, con el fin de mejorar el desenlace, el pronóstico y la morbilidad posquirúrgica.
Introduction. Postoperative pancreatic fistula is one of the most important complications in hepatobiliopancreatic surgery. Its diagnosis is made by the presence of an amylase level in the drainage fluid at least three times above the serum amylase value from the third postoperative day. The objective of this study was to characterize patients with postoperative pancreatic fistula at our institution, evaluating the importance of early detection and to establish a timely management. Methods. Descriptive, retrospective study that included patients who underwent pancreatoduodenectomy with a diagnosis of postoperative pancreatic fistula as a complication of hepatobiliopancreatic surgery at the Hospital Internacional Colombia, between January 2017 and December 2020. Patients with another type of procedure performed by this specialty and those who did not decide to participate in the study were excluded. Results. A total of 69 patients were included, the median age was 57 years with a predominance of females (n=38; 55.1%). 33.3% (n=24) of the operated patients developed postoperative pancreatic fistula, with 23.2% having a biochemical leak, grade B in 8.7% and grade C in 2.9%, for whom expectant management, ultrasound control and reintervention were indicated, respectively. Five patients died (7.2%). Conclusions. Pancreatic fistula is a complication to take into account in all patients undergoing pancreatoduodenectomy. There are strategies that can reduce the incidence of this complication and thus improve not only the outcome but also the prognosis and postoperative morbidity.

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
BACKGROUND: Pancreatic cancer is the seventh leading cause of death worldwide, with ductal adenocarcinoma as the most frequent neoplasm. Half of the patients who are diagnosed have metastases at the time of diagnosis. OBJECTIVE: A review of the treatment of resectable pancreatic adenocarcinoma with oligometastatic disease was carried out in order to present an overview of the existing evidence. METHOD: A bibliographic search was carried in PubMed/Medline, Clinical Key and Index Medicus vhith MESH terms, from the year 1993 to 2022. RESULTS: Patients with liver or lung metastases due to pancreatic ductal adenocarcinoma who undergo surgery and chemotherapy have a longer survival in carefully selected patients. CONCLUSIONS: The evidence regarding surgery in patients with pancreatic ductal adenocarcinoma and oligometastasis is limited and further randomized controlled trials are needed for both scenarios. As well as established criteria that help the selection of patients who can receive this type of treatment.
ANTECEDENTES: El cáncer pancreático es la séptima causa de muerte en el mundo, siendo el adenocarcinoma ductal del páncreas la neoplasia más frecuente. La mitad de los pacientes que son diagnosticados presentan metástasis al momento del diagnóstico. OBJETIVO: Se realizó una revisión sobre el tratamiento del adenocarcinoma pancreático resecable con enfermedad oligometastásica con el fin de presentar un panorama sobre la evidencia existente. MÉTODO: Se realizó una búsqueda bibliográfica en PubMed/Medline, Clinical Key e Index Medicus con términos MESH desde 1993 hasta 2022. RESULTADOS: Los pacientes con metástasis hepáticas o pulmonares por adenocarcinoma ductal de páncreas que son sometidos a cirugía y quimioterapia tienen una mayor sobrevida en casos cuidadosamente seleccionados. CONCLUSIONES: La evidencia respecto a la cirugía en pacientes con adenocarcinoma ductal de páncreas y oligometástasis es limitada y se necesitan ensayos controlados aleatorizados adicionales para ambos escenarios, así como criterios bien establecidos que ayuden a la selección de los pacientes que pueden recibir este tipo de tratamiento.

Undifferentiated pleomorphic sarcoma (UPS) is a very aggressive malignant tumor that originates in bone or soft tissues, being its most frequent location in the extremities. We present the case of a 71-year-old man who, two years of follow-up after a lower right limb UPS excision surgery, presented a single metastasis of sarcomatoid origin in the pancreas that was treated by cephalic pancreaticoduodenectomy. Sarcomatoid metastases to the pancreas are extremely rare. Resection of the metastasis is the only therapeutic alternative that has reported benefit in terms of the survival of these patients.

Presentamos el caso de un varón de 71 años que a los dos años de seguimiento tras cirugía de exéresis de un SPI presenta una metástasis única de origen sarcomatoide a nivel del páncreas que se trató mediante duodenopancreatectomía cefálica. Las metástasis sarcomatoides a nivel de páncreas son extremadamente raras. La cirugía de exéresis de la metástasis es la única alternativa terapéutica que ha reportado beneficio en cuanto la supervivencia de estos pacientes.
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
Background: The incidence of Grade C postoperative pancreatic fistula ranges from 2 to 11% depending on the type of pancreatic resection. This complication may frequently require early relaparotomy and the surgical approach remains technically challenging and is still associated with a high mortality. Infectious complications and post-operative hemorrhage are the two most common causes of reoperation. Summary: The best management of grade C pancreatic fistulas remains controversial and ranges from conservative approaches up to completion pancreatectomy. The choice of the technique depends on the patient's conditions, intraoperative findings, and surgeon's discretion. A pancreas-preserving strategy appears to be attractive, including from simple to more complex procedures such as debridement and drainage, and external wirsungostomy. Completion pancreatectomy should be reserved for selected cases, including stable patients with severe infection complication or hemorrhage after pancreatic fistula who do not respond to pancreas-preserving procedures. Key Messages: This review describes the current options for management of grade C pancreatic fistula after pancreatoduodenectomy with regard to indication, choice of procedure and outcomes of the different approaches.
RESUMO
Resumen Introducción: Los tumores periampulares se definen como lesiones ubicadas en un radio de 2 cm alrededor de la ampolla de Vater, constituidos por 4 tipos de neoplasias con una alta tasa de malignidad que pueden originarse en páncreas, ampolla, vía biliar distal o duodeno. El manejo quirúrgico a través de la pancreatoduodenectomía sigue siendo la mejor elección en términos de resección curativa. Objetivo: Caracterizar los tumores peri-ampulares tratados en nuestra institución y que fueron llevados a pancreatoduodenectomía, asociando la relación entre tipo de tumor y complicaciones posoperatorias. Material y Método: Estudio transversal, retrospectivo y observacional con seguimiento a 45 pacientes sometidos a pancreatoduodenectomía en el Hospital Internacional de Colombia - Fundación Cardiovascular entre enero de 2011 y marzo de 2020 con diagnostico histopatológico de tumor peri-ampular. Resultados: Se realizaron 75 pancreatoduodenectomía de las cuales 45 pacientes presentaron tumor peri-ampular, siendo de origen pancreático en un 44%, seguido de ampolla 40%, vía biliar distal 8,8% y duodenal 6,6%. Las complicaciones posoperatorias más frecuentes fueron fístula pancreática y vaciamiento gástrico retardado. Falleció 1 paciente. Conclusión: La pancreatoduodenectomía es un procedimiento con alta morbilidad. Gracias al avance tecnológico, el diagnóstico de patología peri ampular es cada vez más exacto. El tipo de tumor peri-ampular puede influir no solo en su pronóstico, sino también en su morbilidad posquirúrgica.
Introduction: Periampullary tumors are defined as lesions that are located in a radius of 2 centimeters around the ampulla of Vater, constituted by 4 types of neoplasms with a high rate of malignancy originated in the pancreas, ampulla, distal bile duct or duodenum. Surgical management through the pancreatoduodenectomy remains the best choice in terms of curative resection. Objetive: To characterize periampullary tumors treated in our institution with pancreatoduodenectomy, associating the relationship between tumor type and postoperative complications. Material and Method: Cross-sectional, retrospective, observational study with a follow-up of 45 patients underwent pancreatoduodenectomy in the Hospital Internacional de Colombia - Fundación Cardiovascular between January 2011 and March 2020 with histopathological diagnosis of periampullary tumor. Results: Were performed 75 pancreatoduodenectomies, 45 patients presented with Periampullary tumor, 44% being of pancreatic origin, followed by ampulla 40%, distal bile duct 8.8% and duodenal 6.6%. Most frequent postoperative complications were pancreatic fistula and delayed gastric emptying. Mortality was of 1 patient. Conclusión: Pancreatoduodenectomy is a procedure with a high morbidity rate. Thanks to technological advances, the diagnosis of periampullary pathology is increasingly accurate. The type of periampullary tumor may influence not only in its prognosis, but also in its post-surgical morbidity.

ABSTRACT - BACKGROUND: Several methods have been proposed for the reconstruction of digestive transit after pancreatoduodenectomy. Biliary anastomosis positioned before gastric anastomosis helps reduce postoperative reflux and cholangitis. AIMS: The objective of this study was to present the anatomical sequence of gastric and biliary continuity after pancreatoduodenectomy in patients with pancreatic tumor and to evaluate the short- and long-term results in an initial series of cases. METHODS: Two techniques were used: one with Roux-en-Y reconstruction and pancreaticojejunostomy and the other with a single jejunal loop and pancreatogastroanastomosis. In both the cases, the gastric anastomosis was placed performed before the biliary one. An analysis of demographic data, Wirsung's duct and common bile duct dilatation, the use of percutaneous drainage, and postoperative complications was carried out. RESULTS: A total of seven patients (four men and three women), with a mean age of 62 years, underwent surgery. All cases had Wirsung's duct and common bile duct dilatation. A percutaneous external biliary drainage was performed in four patients. There were three postoperative complications: one related to delayed gastric emptying and two related to wound infections. During a median follow-up of 12 months, no episode of cholangitis was recorded. CONCLUSIONS: Elevated percentages of cholangitis are reported in different reconstructions after pancreatoduodenectomy, and it is difficult to conclude reflux as the main etiology. The proposed gastric and biliary reconstructions show conforming results, facilitating posterior endoscopic access. Late follow-up and large number of cases may help assess whether the etiology of postoperative cholangitis is reflux or other factors unrelated to the order of the anastomoses.
RESUMO - RACIONAL: Múltiplas são as propostas de reconstrução do trânsito digestivo após as pancreadoduodenectomias. A anastomoses biliar posicionada antes da anastomose gástrica oferece argumentos de evitar refluxo e colangite pós-operatória. OBJETIVOS: apresentar a técnica de continuidade gástrica e biliar com sequência anatômica após pancreatoduodenectomia em portadores de adenocarcinoma de pâncreas e avaliar os resultados em uma série inicial de casos. MÉTODOS: Foram utilizadas duas técnicas, uma com reconstrução em Y de Roux e pancreaticojejunostomia e outra com alça única de jejuno e pancreatogastroanastomose. Em ambos, a anastomose gástrica foi colocada antes da biliar. E análise de dados demográficos, dilatação do ducto de Wirsung e ducto biliar comum, uso de drenagem percutânea e complicações pós-operatórias. RESULTADOS: Foram operados 7 doentes: 4 homens e 3 mulheres, com média de idade de 62 anos. Todos os casos apresentavam dilatação do ducto de Wirsung e ducto biliar comum. Em 4 dos casos foi realizada drenagem biliar externa percutânea. Ocorreram 3 complicações pós-operatórias, 1 esvaziamento gástrico retardado e 2 infecções de ferida operatória. Durante o acompanhamento médio de 12 meses, não foram registrados episódios de colangite. CONCLUSÕES: Porcentagens elevadas de colangite são relatadas nas diferentes reconstruções após pancreatodudenectomias, sendo difícil atribuir de forma absoluta o refluxo como a principal etiologia. As reconstruções gástrica e biliar propostas são mais harmoniosas, além de facilitar o acesso endoscópico posterior. Seguimento tardio e número maior de casos, pode esclarecer se a etiologia da colangite pós-operatória pode ser o refluxo ou a outros fatores não relacionados à ordem das anastomoses.
RESUMO
Pancreatoblastoma (PB) is a rare malignant tumor in adults. It has an overall incidence of 0.004 per 100,000 inhabitants. Its diagnosis with fine-needle aspiration (FNA) is difficult due to multiple differentiation lines present on PB that overlap with other tumors. A 76-year-old male patient presented with jaundice, weight loss of 10 kg in 6 months, and appetite loss. Abdominal computed tomography scan showed a tumor in the pancreas head. Transendoscopic ultrasound with FNA biopsy revealed a malignant epithelial neoplasia compatible with PB with immunohistochemistry CK19 (+), P63(+), synaptophysin (-), and Ki67 50%. The patient underwent surgical resection and adjuvant chemotherapy. Currently, the patient is in follow-up with the latest imaging showing no evidence of disease at 32 months after his initial diagnosis. PB is an uncommon malignant neoplasia with an aggressive behavior. Its diagnostic and therapeutic protocols are unclear. Its preoperative diagnosis may be difficult since its imaging features and serological markers are non-specific. However, FNA may be useful in some situations. Surgical resection is currently the recommended treatment that is associated with the best long-term survival.
RESUMO
Resumen Introducción Los tumores del estroma gastrointestinal (GIST) corresponden al 1% de todas las neoplasias gastrointestinales, sin embargo, sólo el 3-5% de estos se desarrollan en el duodeno. Objetivo Reportar el caso de un paciente masculino con localización atípica de un tumor de estroma gastrointestinal y su manejo. Caso clínico paciente masculino de 50 años con antecedente de traumatismo encefalo craneano (TEC) con daño orgánico cerebral secundario, tabaquismo, consumidor de alcohol ocasional y sometido a quistectomía branquial en la infancia, que consulta en el servicio de urgencias por cuadro de hemorragia digestiva alta con compromiso hemodinámico. Tras realizar endoscopia digestiva alta (EDA), resonancia nuclear magnética (RNM) y tomografía computada (TC) de abdomen, se pesquisa masa tumoral en segunda porción de duodenal. Discusión A pesar de que la presentación clínica de los GIST es variable, lo más frecuente es que sean pacientes asintomáticos. En algunas ocasiones, al igual que en este reporte, pueden presentarse con dolor abdominal y/o hemorragia digestiva alta. El diagnóstico preoperatorio fue difícil ya que el estudio con imágenes (TC, RNM, EDA) sólo permite establecer la sospecha; el diagnóstico definitivo se realizó con biopsia (no contamos con endosonografía en nuestro centro). Debido a los sitios de reparo anatómico, no existe una cirugía estandarizada; en este caso, debido a la localización, infiltración y características, se decidió realizar una pancreatoduodenectomía.
Introduction Gastrointestinal stromal tumors (GIST), corresponds to 1%, of all gastrointestinal neoplasms, however, only 3%-5% developed in duodenum. Aim To report a case of a male patient with atypical location of gastrointestinal stroma tumor and the treatment proposed. Case report 50-year-old male patient, with medical history of organic brain damage secondary a traumatic brain injury, smoker, occasional alcohol consumer and branquial cystomy during childhood. Consulted in the emergency department for a high digestive hemorrhage case with hemodynamic compromise. Upper digestive endoscopy, computed tomography and nuclear magnetic resonance were performed, which impresses tumor-like lesion in the second duodenal portion. Discussion Although the GIST clinical presentation is variable, most often they are asymptomatic patients. In some times, as in this report, they may present with abdominal pain and/or upper gastrointestinal bleeding. The preoperative diagnosis was difficult, because the imaging study (CT, RNM, EDA) only stablished the suspicion and the final diagnosis was made by biopsy (we don't have endosonography in our center). Due to the anatomic repair, there is not a standardized surgery, in this case, due tumor location, infiltration and characteristics, it was decided to perform a pancreatoduodenectomy.

BACKGROUND: Pancreatectomy plus celiac axis resection (CAR) is performed in patients with locally advanced pancreatic cancer. The morbidity rates are high, and no survival benefit has been confirmed. It is not known at present whether it is the type of pancreatectomy, or CAR itself, that is the reason for the high complication rates. METHODS: Observational retrospective multicenter study. INCLUSION CRITERIA: patient undergoing TP, PD or DP plus CAR for a pancreatic cancer. RESULTS: Sixty-two patients who had undergone pancreatic cancer surgery (PD,TP or DP) plus CAR were studied. Group 1: 17 patients who underwent PD/TP-CAR (13TP/4PD); group 2: 45 patients who underwent DP-CAR. Groups were mostly homogeneous. Operating time was longer in the PD/TP group, while operative complications did not differ statistically in the two groups. The number of lymph nodes removed was higher in the PD/TP group (26.5 vs 17.3), and this group also had a higher positive node ratio (17.9% vs 7.6%). There were no statistical differences in total or disease-free survival between the two groups. CONCLUSION: It seems that CAR, and not the type of pancreatectomy, influences morbidity and mortality in this type of surgery. International multicenter studies with larger numbers of patients are now needed to validate the data presented here.

La operación de Whipple es el procedimiento quirúrgico de mayor complejidad en cirugía abdominal, este se realiza en pacientes con tumores de la encrucijada pancreatoduodenal, es la única alternativa para tratamiento curativo en fases tempranas de la enfermedad. Objetivo: Determinar los resultados del procedimiento Whipple, en pacientes intervenidos con tumores de la encrucijada pancreatoduodenal en el Hospital General de Enfermedades del Instituto Guatemalteco de Seguridad Social, en el periodo de enero 2,015 a enero 2,020. Método: Descriptivo, observacional, retrospectivo. Resultados: Se incluyeron 42 procedimientos de Whipple, 29 (69%) casos del género masculino y 13 (31%) para el género femenino. La edad media fue de 61.5 años, el 54% presentaban comorbilidad asociada. El 24% utilizo transfusión transoperatoria de hemoderivados, el tiempo quirúrgico de 5.5 horas. La reintervención fue del 4.7%. Complicaciones postoperatorias tempranas 18%. La histología más común fue el carcinoma de cabeza de páncreas en el 43%. La mortalidad postoperatoria temprana fue del 4.7%. El OR de complicaciones asociadas a comorbilidades fue de 1.7 con un IC 0.3046-7.20 y un valor de P: 0.9251 que no es estadísticamente significativo. Conclusiones: Los tumores pancreatoduodenales en nuestra población se presentan en edades más tempranas a lo reportado. La morbimortalidad es similar a lo reportado en otros estudios a nivel latinoamericano, sin embargo las complicaciones están más elevadas que las mejores series internacionales. No existe asociación entre el riesgo de complicaciones con comorbilidades del paciente. (AU)
Whipple operation is the most complex surgical procedure in abdominal surgery, it's performed in patients with tumors of the pancreaticoduodenal crossroads, it is the only alternative for curative treatment in early stages of the disease. Objective: To determine the results of the Whipple procedure in patients operated on with tumors of the ancreaticoduodenal crossroads at the Hospital General de Enfermedades del IGSS in the period from January 2015 to January 2020. Method: Descriptive, observational, retrospective. Results: fourtytwo Whipple procedures were included, 29 (69%) cases of the male gender and 13 (31%) for the female gender. The mean age was 61.5 years, 54% had associated comorbidity. Twentyfour percent used intraoperative transfusion of blood products and surgical time of 5.5 hours. Reoperation was 4.7% with early postoperative complications of 18%. The most common histology was carcinoma of the head of the pancreas in 43%. Early postoperative mortality was 4.7%. The OR of complications associated with comorbidities was 1.7 with a CI 0.3046-7.20 and a P value: 0.9251, which is not statistically significant. Conclusions: Pancreaticoduodenal tumors in our population present at an earlier age than reported. Morbidity and mortality is similar to that reported in other studies. There is no association between the risk of complications with patient comorbidities. (AU)

BACKGROUND: Pancreatoduodenectomy or Whipple's operation, is the elective surgical procedure to treat different periampullary diseases. Through the years this surgery has been doing open, but in the lasts decades thanks to the improve technology and trained surgeons, today is feasible doing it laparoscopic with good results. OBJECTIVE: To present the initial experience and results in totally laparoscopic pancreatoduodenectomy in Hospital Regional ISSSTE Puebla, reporting the second number of cases in México. METHOD: Since July 2014-July 2018, 8 patients has been operated by totally laparoscopic pancreatoduodenectomy, 7 in Hospital Regional ISSSTE Puebla and 1 in a private Hospital. RESULTS: Evaluating all the patients, not one had mortality during operation, no morbidity or immediate reoperation, so the results are favourable. CONCLUSION: Laparoscopic pancreatoduodenectomy is a very complex procedure but feasible, and good results depends on various factors, like the appropriate patient selection.
ANTECEDENTES: La pancreatoduodenectomía o cirugía de Whipple es el procedimiento de elección en el tratamiento de las enfermedades periampulares.

Resumen El cáncer gástrico es una patología de alta incidencia en Chile. Afortunadamente es baja la incidencia de márgenes R1 cuando se realiza una cirugía con intención curativa. Al tener un tumor subcardial o cardial es perentorio realizar una biopsia rápida (intraoperatoria), en caso que ésta resulte positiva, es difícil tomar una decisión sobre qué realizar a continuación, ya que el realizar una esofagoyeyunoanastomosis intratorácica aumenta el riesgo quirúrgico. Para esto, es de suma importancia tener la información de las características histopatológicas del tumor, el riesgo de filtración, la recurrencia, la sobrevida, las terapias adyuvantes y la realidad país. Se realizó una revisión de la literatura con el fin de poder guiar la toma de decisiones.
Gastric cancer is a pathology with a high incidence in Chile, fortunately, the incidence of R1 margins is low when performing surgery with curative intent. When having a sub cardial or cardial tumor, it is essential to perform a rapid (intraoperative) biopsy, if this is positive when cutting the esophagus just under the pillars, it is difficult to make the decision of what to do next, since performing an inthrathoracic esophagojejunostomy increases the surgical risk. For this, it is very important to have information about the histopathological characteristics of the tumor, the leakage risk, there currence, the survival, the adjuvant therapies and the reality of the country. A review of the literature was done in order to guide the decisions.

BACKGROUND: Lymph node metastasis (LNM) is a strong prognostic factor in the cancer of the pancreatobiliary tree, but it is influenced by the number of lymph nodes (LNs). The lymph node ratio (LNR) is considered a more reliable factor than the number of LNM. The aim was to examine the LN retrieval and the LNR of 3 pathologic work-up strategies. METHODS: Pancreaticoduodenectomies (n = 165) were analyzed comparing 3 pathological dissection techniques, classified as "control," "Verbeke method," and "Adsay method" groups. RESULTS: The mean of the dissected LNs and the number of cases with >20 LNs were superior in the Adsay method group, compared with the other groups ( P < .001). The LNR was different between the Adsay and Verbeke groups (0.144 vs 0.069, P = .032). The median of the 3 positive LNs was associated with decreased survival compared with an absence of LNM (3-year specific survival of 48% vs 22%, P = .011). In the multivariate analysis, LNM (hazard ratio = 6.148, 95% confidence interval = 2.02-8.1, P = .042) and the evaluation of >15 LNs (hazard ratio = 12.52, 95% confidence interval = 5.51-21.01, P = .001) were independent predictors of survival. CONCLUSION: The Adsay technique for LN retrieval was associated with a better LN count, more cases with LNM, and an LNR >0.1.
