Divertículo de Meckel con tumor neuroendocrino: presentación inusual / Meckel's diverticulum with neuroendocrine tumor: unusual presentation

El divertículo de Meckel es una malformación congénita que suele presentarse como un hallazgo incidental asintomático. Puede complicarse por procesos inflamatorios o tumores, cursando con sintomatología abdominal sumamente inespecífica, lo que complica su diagnóstico oportuno. Aunque la incidencia de neoplasias malignas en estos divertículos es baja, los tumores neuroendocrinos son los más representativos. Presentamos el caso de una paciente de 72 años que consultó por dolor abdominal y deposiciones melénicas, con múltiples nódulos intrahepáticos sugestivos de tumores neuroendocrinos y hallazgo intraoperatorio incidental de diverticulitis aguda de Meckel con metástasis peridiverticular de un tumor neuroendocrino.

Meckel's diverticulum is a congenital malformation that usually presents as an incidental finding. It can be complicated by inflammatory processes or tumors, with non-specific abdominal symptoms which delay its timely diagnosis. Although the incidence of malignant neoplasms in these diver-ticula is low, neuroendocrine tumors are the most representative. We present the case of a 72-year-old female patient who consulted for abdominal pain and melenic bowel movements, with multiple intrahepatic nodules suggestive of neuroendocrine tumors and an incidental intraoperative finding of acute Meckel's diverticulitis with peridiverticular metastasis of a neuroendocrine tumor.

Long-Term Outcomes of Laparoscopic Common Bile Duct Exploration Through Diathermy, Choledochotomy, and Primary Closure: A 6-Year Retrospective Cohort Study.

Background and Objective: Choledocholithiasis is a frequent pathology, unfortunately when its endoscopic management fails, there is no consensus of how it should be addressed. The aim of this study was to evaluate the safety, feasibility, and long-term outcomes of laparoscopic common bile duct exploration (LCBDE) using electrosurgery (coagulation) for choledochotomy followed by primary closure after endoscopic treatment failure. Materials and Methods: A retrospective cohort study of patients who underwent LCBDE from 2013 to 2018 was conducted in Bogotá, Colombia. Clinical demographics, operative outcomes, recurrence rate of common bile duct stones, and long-term bile duct complications were analyzed. A descriptive analysis was performed. Results: A total of 168 patients were analyzed. Most of the patients were males (53.37%) with a median age of 73 years with no comorbidities (65%). Stone clearance was successful in 167 patients (99.4%). Nonlethal complications were noted in 3 patients during the surgery or in the immediate postoperative (1.79%) and managed with T-tube or endoscopically. No cases of mortality surgery related were observed. There were no signs of any type of biliary injury or stricture observed in any of the patients during the 24-month follow-up period. Conclusions: LCBDE with diathermy and primary closure is a safe and effective treatment option for choledocholithiasis for failed endoscopic retrograde cholangiopancreatography in terms of long-term outcome as well as short-term outcome.

Enucleación esofágica de leiomioma asistida por robot: reporte de un caso y revisión de la literatura / Case report of robot-assisted esophageal enucleation of leiomyoma and literature review

Resumen Introducción: los leiomiomas esofágicos son tumores benignos, que son resecados por enucleación esofágica cuando son mayores de 5 cm o en lesiones de cualquier tamaño que sean sintomáticos o sospechosos de malignidad. Tradicionalmente, se ha realizado la resección por técnica de enucleación abierta; sin embargo, la cirugía mínimamente invasiva ha surgido como una técnica con grandes ventajas y, en especial, la tecnología robótica parece ofrecer ventajas. Caso clínico: se reporta un caso de leiomioma esofágico del esófago medio con enucleación mediante el uso de una técnica toracoscópica asistida por robot. La esofagoscopia intraoperatoria y la transiluminación fueron complementos útiles para identificar el esófago y desarrollar un plano de disección extramucosa seguro, que junto con la asistencia robótica parecen minimizar los riesgos intraoperatorios, entre ellos, potencialmente la probabilidad de lesión mucosa, y mejoran el tiempo de recuperación postoperatoria.

Abstract Introduction: Esophageal leiomyomas are benign tumors which are resected by esophageal enucleation when they are symptomatic, suspected of malignancy, or larger than 5 cm. Traditional resection uses the open enucleation technique, but minimally invasive surgery has emerged as a technique that has great advantages, especially when combined with robotic technology. Case report: We report a case of leiomyoma of the middle esophagus with treated with enucleation using a robotic-assisted thoracoscopic technique. Intraoperative esophagoscopy and transillumination were useful for identifying the esophagus and developing a plan of safe extra mucosal dissection. Together with robotic assistance this seems to minimize intraoperative risks including that of mucosal injury while also improving postoperative recovery time.
