RESUMO

Introducción: el divertículo de Meckel es la anomalía congénita más frecuente del tracto gastrointestinal. Puede presentarse con hemorragia, obstrucción intestinal o diverticulitis, complicaciones que disminuyen con la edad, por lo que en el adulto el diagnóstico suele ser incidental. El tratamiento de las complicaciones es quirúrgico, mediante diverticulectomía o resección segmentaria del intestino delgado, dependiendo de sus características morfológicas. Objetivo: analizar nuestra experiencia en el manejo del divertículo de Meckel complicado en un período de 15 años. Diseño: estudio descriptivo, observacional, transversal, retrospectivo. Material y métodos: se revisaron las historias clínicas de los pacientes operados por divertículo de Meckel complicado en el Servicio de Cirugía General del Hospital San Roque durante el periodo 2007-2022. Se registraron datos demográficos, presentación clínica, diagnóstico preoperatorio, tratamiento quirúrgico, complicaciones postoperatorias y hallazgos histopatológicos. Resultados: se incluyeron 25 pacientes, 21 (84%) hombres, 3 menores de 18 años. La presentación clínica fue un síndrome de fosa iliaca derecha en el 80% de los casos, obstrucción intestinal en el 16% y hemorragia en el 4%. En solo 2 casos se realizó el diagnóstico preoperatorio, confirmado mediante tomografía computada. Se realizó diverticulectomía en el 68% de los pacientes y resección segmentaria el 32%. El abordaje fue laparotómico en el 64%, principalmente en el periodo inicial y laparoscópico en el 36%. Hubo una complicación IIIb de Clavien-Dindo en un paciente pediátrico tratado con drenaje percutáneo. En un solo paciente (4%), que se presentó con hemorragia digestiva masiva, se encontró epitelio de tipo gástrico y páncreas ectópico en el divertículo. Conclusiones: En nuestra experiencia el divertículo de Meckel complicado se presentó predominantemente en hombres. La complicación más frecuente en el adulto fue la diverticulitis. El diagnóstico preoperatorio fue infrecuente y realizado por tomografía computada. La diverticulectomía es suficiente en la mayoría de los casos. Actualmente, la laparoscopia es una herramienta segura, rentable y eficiente que permite el diagnóstico y tratamiento oportunos de esta entidad. (AU)

Introduction: Meckel's diverticulum is the most common congenital malformation of the gastrointestinal tract. It can present with bleeding, intesti-nal obstruction or diverticulitis, complications that decrease with age, so in adults the diagnosis is usually incidental. Treatment of complications is surgical, through diverticulectomy or segmental resection of the small intestine, depending on its morphological characteristics. Objective: to analyze our experience in the management of complicated Meckel's diverticulum over a period of 15 years. Design: descriptive, observational, cross-sectional, retrospective study. Materials and methods: the medical records of patients operated on for complicated Meckel's diverticulum in the General Surgery Service of the San Roque Hospital during the period 2007-2022 were reviewed. Demo-graphic data, clinical presentation, preoperative diagnosis, surgical treatment, postoperative complications, and histopathological findings were recorded. Results: twenty-five patients were included, 21 (84%) men, 3 under 18 years of age. The clinical presentation was a right iliac fossa syndrome in 80% of cases, intestinal obstruction in 16% and hemorrhage in 4%. In only 2 cases was the preoperative diagnosis made, confirmed by computed tomography. Diverticulectomy was performed in 68% of patients and segmental resection in 32%. The approach was by laparotomy in 64%, mainly in the initial period, and by laparoscopy in 36%. There was a Clavien-Dindo IIIb complication in a pediatric patient treated with percutaneous drain-age. In only one patient (4%), who presented with massive gastrointestinal bleeding, gastric-type epithelium and ectopic pancreas were found in the diverticulum. Conclusions: In our experience, complicated Meckel's diverticulum occurred predominantly in men. The most frequent complication in adults was diverticulitis. Preoperative diagnosis was infrequent and was made by computed tomography. Diverticulectomy is sufficient in most cases. Currently, laparoscopy is a safe, profitable and efficient tool that allows for the timely diagnosis and treatment of this entity. (AU)

RESUMO

El divertículo de Meckel es la malformación gastrointestinal congènita más frecuente y se produce por la involución parcial o total del conducto onfalomesentérico durante el desarrollo embrionario, resultando en un divertículo verdadero, puesto que contiene todas las capas del intestino delgado. Posee una incidencia de 0,6-4% en la población general y corresponde a la principal causa de hemorragia digestiva baja en pacientes pediátricos. Mayoritariamente, permanece asintomático hasta la adultez, pudiendo presentar cuadros clínicos sugerentes de apendicitis aguda, obstrucción intestinal y hemorragia digestiva baja. El hallazgo del divertículo suele ser incidental y en solo 4-6% de las ocasiones se encuentra como estudio dirigido de esta anormalidad. Existen múltiples estudios diagnósticos disponibles, pasando por la tomografía computarizada (TC), cintigrafía con pertecnetato de Tecnecio-99m (Tc-99m), videocápsula endoscópica y la laparoscopía/laparotomía. El manejo del divertículo de Meckel es quirúrgico, especialmente, debido a sus múltiples complicaciones, siendo detalladas en el presente artículo. El uso de técnicas mínimamente invasivas y las mejores tecnologías y métodos de detección han permitido disminuir la mortalidad de las complicaciones del divertículo de Meckel. Finalmente, esta patología supone un reto para cualquier especialista, puesto que la baja incidencia y el cuadro clínico similar a enfermedades diverticulares significa un mayor reto tanto en el diagnóstico como en el manejo.

Meckel's diverticulum is the most common congenital gastrointestinal malformation and is caused by partial or total involution of the omphalomesenteric duct during embryonic development, resulting in a true diverticulum, since it contains all the layers of the small intestine. It has an incidence of 0.6-4% in the general population and is the main cause of lower gastrointestinal bleeding in pediatric patients. Most of them remain asymptomatic until adulthood, and may present clinical symptoms suggestive of acute appendicitis, intestinal obstruction and lower gastrointestinal bleeding. The finding of the diverticulum is usually incidental and only 4-6% of the time it is found as a directed study of this abnormality. There are multiple diagnostic studies available, including computed tomography (CT), Technetium-99m pertechnetate (Tc-99m) scintigraphy, video capsule endoscopy, and laparoscopy/laparotomy. The management of Meckel's diverticulum is surgical, especially due to its multiple complications, which are detailed in this article. The use of minimally invasive techniques and the best technologies and detection methods have made it possible to reduce the mortality of Meckel's diverticulum complications. Finally, this pathology is a challenge for any specialist, since the low incidence and symptoms similar to diverticular diseases pose a greater challenge both in diagnosis and management.

RESUMO

Tumors of the Meckel cave are very rare lesions, especially if they are malignant. We report the case of a patient who presented with a breast metastasis in the Meckel cave and a clinical presentation similar to that of a fifth nerve schwannoma.

Os tumores do cavo de Meckel são lesões muito raras, especialmente se forem malignos. Relatamos o caso de uma paciente que apresentou metástase mamária no cavo de Meckel e quadro clínico semelhante a schwannoma do quinto nervo.

RESUMO

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. (AU)

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.

RESUMO

INTRODUCTION AND IMPORTANCE: Meckel's diverticulum (MD) is a common congenital malformation of the digestive tract, often asymptomatic but occasionally leading to complications such as bowel obstruction and ischemia. Timely recognition and treatment of these complications are crucial. PRESENTATION OF CASE: We report the case of a 27-year-old male patient presenting with complete intestinal obstruction and ischemia of the ileum due to a fibrous band associated with MD. The patient presented with severe abdominal pain lasting for 10 h. Physical examination revealed a distended abdomen, antalgic position, and positive decompression. Laboratory tests showed leukocytosis and elevated lactic acid levels. Computed tomography revealed dilated small bowel loops with signs of intestinal ischemia. Emergency exploratory laparoscopy confirmed a complete ileum with ischemia and identified a fibrous band originating from the mesentery, strangulating the affected loop. The fibrous band was dissected and sectioned, confirming its association with the MD, which was resected with subsequent recovery of peristalsis and vascularization of the compromised segment. The patient had a favorable postoperative recovery without complications. DISCUSSION: MD is a rare cause of bowel obstruction, requiring a high index of suspicion for diagnosis. Despite the challenges in preoperative identification, early surgical intervention is crucial to prevent adverse outcomes. This case emphasizes the importance of promptly recognizing and managing MD-related complications to optimize patient outcomes. CONCLUSION: MD should be considered in cases of acute occlusive abdomen, despite its infrequent occurrence. Early diagnosis and timely surgical intervention are essential to minimize morbidity and mortality associated with MD-related complications.

RESUMO

Meckel's diverticulum corresponds to the aberrant involution of the omphalo-mesenteric canal or vitelline duct, which is located at the level of the antimesenteric border of the terminal ileum. It is the most common structural anomaly of the gastrointestinal tract, it is almost always asymptomatic and its diagnosis is usually incidental, however the complication with diverticulitis is an unusual condition. We describe the case of a 65-year-oldman, who was admitted from another institution with a diagnosis of acute abdomen. On physical examination, he presented signs of peritoneal irritation with evidence of leukocytosis and neutrophilia in the admission blood count. Computerized tomography of the abdomen with intra venous contrast was performed, which was interpreted as complicated Meckel's diverticulitis, being corroborated during the surgical act and confirmed by pathological anatomy. Meckel's diverticulitis is a rare entity, however it is important to recognize it within the differential diagnoses of acute abdomen, which will allow prompt intervention and a favorable outcome.

RESUMO

RESUMEN El divertículo de Meckel es la malformación congénita más frecuente del tracto gastrointestinal. Puede permanecer completamente oculto sin dar síntomas o puede ser causa de abdomen agudo quirúrgico en donde se debe descartar patología inflamatoria, infecciosa y/o mecánica. Se presenta un caso excepcional de una obstrucción intestinal producido por una hernia interna generada por un divertículo de Meckel en el hiato de Winslow.

ABSTRACT Meckel's diverticulum is the most common congenital defect of the gastrointestinal tract. It may remain asymptomatic or may cause acute abdomen requiring surgery due to inflammation, infection or mechanical obstruction. We report case of small bowel obstruction produced by an internal hernia generated by a Meckel's diverticulum in the foramen of Winslow.

RESUMO

OBJECTIVE: Meckel diverticulum (MD) is a common malformation of the digestive tract, often accompanied by serious complications. It is important to find safe and effective diagnostic methods for screening MD. The aim of this study was to evaluate the effectiveness of a technetium-99m (Tc-99m) scan for pediatric bleeding MD. METHODS: The authors conducted a systematic review of studies published in PubMed, Embase, and Web of Science before 1 January 2023. Studies based on PICOS were included in this systematic review. The flow chart was made by PRISMA software. The quality of included studies was assessed by RevMan5 software (QUADAS-2: Quality Assessment of Diagnostic Accuracy Studies-2). The sensitivity, specificity, and other measurements of accuracy were pooled using Stata/SE 12.0 software. RESULTS: Sixteen studies with 1115 children were included in this systematic review. A randomized-effects model was used for the meta-analysis because of significant heterogeneity. The combined sensitivity and specificity were 0.80 [Confidence Interval (95% CI, 0.73-0.86) and 0.95 (95% CI, 0.86-0.98)], respectively. The area under the curve (AUC) was 0.88 (95% CI, 0.85-0.90). Publication bias (Begg's test p = 0.053) was observed. CONCLUSION: Tc-99m scan has high specificity, but moderate sensitivity, which is always influenced by some factors. Hence, the Tc-99m scan has some limitations in the diagnosis of pediatric bleeding MD.

RESUMO

Background: Meckel's diverticulum is a rare congenital pathology among newborns. Nevertheless, it is an uncommon abdominal pathology in the adult population. Therefore, we aim to provide a detailed account of our surgical approach in treating 27 cases of Meckel's diverticulum. Methods: This study is a cross-sectional analysis that utilized a database with prospectively collected data from 2004 to 2022. All patients under the age of 18 were excluded from the population. We described the population's demographic characteristics, symptoms, anatomopathological study, surgical technique, complications, morbidity, and mortality. A subgroup analysis was performed between the symptomatic and asymptomatic patients. Results: A total of 27 patients who underwent surgical resection for a posteriorly diagnosed Meckel's diverticulum were included. The male population accounted for 81.4% (n = 22) of the sample size. The symptomatic group consisted of 18 male and four female patients. Abdominal pain was the predominant symptom in 85% of the patients. Out of the 22 symptomatic patients, only 9% had a positive perioperative diagnosis of Meckel's diverticulum. All 27 patients with diverticulum diagnosis received the resection through diverticulectomy (n = 6), small bowel resection with end-to-end anastomosis (n = 6), and small bowel resection with lateral to lateral anastomosis (n = 15). The mean distance between the diverticulum and the ileocecal valve was 63.4 cm. The symptomatic group had an average diverticulum length of 3.54 cm, with an average base width of 2.47 cm. In the other group, the values were 2.75 and 1.61 cm. The average length of hospital stay in the symptomatic group was 7.3 days. Conclusions: Meckel's diverticulum is a rare pathology in the adult population. Its presentation varies from asymptomatic to symptomatic patients, and surgery is the cornerstone treatment for this pathology.

RESUMO

ABSTRACT Meckel's diverticulum is the most common gastrointestinal tract anomaly. It arises from the incomplete closure of the omphalomesenteric conduit, which is a true diverticulum at the antimesenteric border of the ileum. Although the majority of patients are asymptomatic, they can present with inflammation, hemorrhage, intussusception, intestinal obstruction, and perforation, among others; this constitutes an important differential diagnosis for acute abdomen. A 19-year-old female sought medical attention because of intermittent diffuse abdominal pain for two months, nausea, and diarrhea. In the requested imaging tests, tomography, and enterotomography, a diagnosis of Meckel's diverticulum with some degree of intussusception was suggested. The patient underwent elective surgical treatment without complications and was discharged on the second postoperative day with clinical improvement. In this section, we review publications on similar cases published in the last five years.

RESUMO

Meckel's diverticulum is the most common congenital defect of the gastrointestinal tract. It is most often silent or asymptomatic. However, acute abdominal signs of obstruction, inflammation, hemorrhage and perforation are possible in other cases. Different foreign bodies can cause perforation of Meckel's diverticulum. We present an 18-year-old male who presented to the emergency department with abdominal pain within 48 previous hours. After evaluation, acute appendicitis was diagnosed and he underwent laparoscopic appendectomy. Meckel's diverticulum perforated by a fish bone was intraoperatively discovered. Incidental appendectomy and segmental resection of the ileum were performed.

RESUMO

Introducción: El divertículo de Meckel es un defecto sacular ubicado en el íleon distal, con una tasa de complicaciones de 4%. La resección quirúrgica está indicada en estas complicaciones, siendo controversial en casos asintomáticos o incidentales. Dentro de las complicaciones existen tumores como los estromales gastrointestinales (GIST). Caso Clínico: Hombre de 57 años, postrado por múltiples factores, presenta úlcera por presión sacra grado IV sobreinfectada y con evolución tórpida. Se decide realizar colostomía terminal, evidenciando un divertículo de Meckel en el intraoperatorio con aspecto sospechoso, por lo cual se decide resecar, resultando en un GIST de bajo riesgo. Se mantiene en seguimiento por 6 meses, sin recidiva tumoral. Discusión: Mientras que la cirugía pareciera ser imperativa en complicaciones, aún existe debate respecto a las indicaciones de resección de divertículo de Meckel hallado incidentalmente en el intraoperatorio por cirugía de otra causa. Si bien puede aumentar la morbimortalidad, la resección estaría indicada según ciertas características como edad, sexo, tamaño y aspecto, dado el riesgo de desarrollo de complicaciones y neoplasias.

Introduction: Meckel's diverticulum is a saccular defect located in the distal ileum, with a complication rate of 4%. Surgical resection is indicated when these complications occur, yet resection in asymptomatic or incidental cases remains controversial. Among these complications, the appearance of tumors such as gastrointestinal stromal (GIST), may occur. Case Report: A 57-year-old male, bedridden due to multi- ple factors, presents with a complicated grade IV sacral pressure ulcer with a torpid evolution. An end colostomy is performed, evidencing a suspicious-looking Meckel's diverticulum intraoperatively, which was resected and resulted to be a low-risk GIST. At a 6-month follow-up, the patient showed no evidence of tumor recurrence. Discussion: While surgery seems to be imperative in complications, there is still a debate regarding the indications for resection of Meckel's diverticulum found incidentally intraoperatively due to surgery for another cause. Although it could increase morbidity and mortality, resection could be indicated according to certain characteristics such as age, sex, size and appearance, given the risk of developing complications and neoplasm.

RESUMO

Small bowel perforation caused by an ingested fish bone is rare but can involve the appendix or Meckel's diverticulum. We report the case of a 25-year-old man who presented to the emergency department with acute abdomen caused by perforation of a Meckel's diverticulum with a fish bone ingested in a Good Friday.

En un 78% se resecó el divertículo de Meckel, 100% de los divertículos resecados corresponden a casos complicados. Desde el año 2018, un 75% del abordaje fue mínimamente invasivo, con un 14% de conversión a cirugía abierta. El tipo de resección del divertículo fue un 77% en su base a través de sección con stappler o sutura manual, La ubicación media del divertículo de Meckel fue 77 cm. Un 14% de los pacientes requirieron reoperación por filtración anastomótica. No hubo mortalidad. Discusión: A diferencia de algunas series, en nuestro estudio existe una mayor proporción de abordaje mínimamente invasivo y mayor cantidad de resección en base del divertículo con resultados aceptables. Conclusión: El presente estudio, presenta una población de 14 pacientes con hallazgo de divertículo de Meckel complicado, a partir de los hallazgos de la cirugía en contexto de urgencias; se cumple el objetivo del estudio de caracterizar en un período de 11 años los resultados quirúrgicos de dicha serie, algo no reportado previamente en la literatura chilena.

Aim: To describe the experience in emergency surgery for Meckel's diverticulum in patients over 15 years of age in a tertiary hospital in the Metropolitan Region. Materials and Method: Retrospective and descriptive observational study, in emergency surgical interventions performed between March 2010 to March 2021 are analyzed. By searching the ward records and electronic file. Results: Within the analyzed period, 14 patients were obtained with a postoperative diagnosis and / or finding of Meckel's diverticulum. Meckel's diverticulum was resected in 78%, 100% of resected diverticula correspond to complicated cases. Since 2018, 75% of the approach was minimally invasive, with 14% conversion to open surgery. The type of resection of the diverticulum was 77% at its base through section with stappler or manual suture. The mean location of Meckel's diverticulum was 77 cm. 14% of the patients required reoperation due to anastomotic leakage. There was no reported mortality. Discussion: Unlike some series, in our study there is a higher proportion of minimally invasive approach and a greater amount of resection based on the diverticulum with acceptable results. Conclusion: These study presents a population of 14 patients with a finding of complicated Meckel's diverticulum, based on the findings of surgery in an emergency setting. the objective of the study is fulfilled to characterize in a period of 11 years the surgical results of this series, something not previously reported in the chilean literature.

RESUMO

RESUMEN El divertículo de Meckel se diagnostica por una complicación. Existen tres complicaciones más comunes: la hemorragia, la inflamación y la oclusión. Esta última se presenta con mayor frecuencia en niños. Tiene mayor incidencia en el sexo masculino, sin embargo, en los últimos años en el municipio Baracoa (Guantánamo, Cuba) se han presentado varios casos, cinco en el año 2019 y uno en el 2020; cuatro de ellos fueron mujeres. Se presenta el caso clínico de una paciente de 62 años de edad, con antecedentes de cirugía abdominal por úlcera duodenal perforada, la cual requirió atención médica en el servicio de guardia de Cirugía, del hospital municipal de Baracoa, por dolor abdominal tipo cólico, vómitos y dificultad en la expulsión de heces y gases. Se hospitalizó con diagnóstico presuntivo de oclusión intestinal mecánica por bridas postquirúrgicas y se realizó laparotomía exploradora, con hallazgo diagnóstico de divertículo de Meckel inflamado. Se concluyó con resección intestinal del segmento de íleon. La paciente evolucionó satisfactoriamente y fue dada de alta al octavo día después de la intervención, sin complicaciones.

ABSTRACT Meckel's diverticulum is diagnosed by a complication. There are three most common complications: hemorrhage, inflammation, and occlusion. The last one occurs more frequently in children. It has a higher incidence in males, however, in recent years in the Baracoa municipality (Guantánamo, Cuba) there have been several cases, five in 2019 and one in 2020; four of them were women. The clinical case of a 62-years-old patient is presented, with a history of abdominal surgery due to perforated duodenal ulcer, which required medical attention in the Surgery on-call service, of the Baracoa municipal hospital, due to colic-type abdominal pain, vomiting and difficulty in expelling stool and gas. She was hospitalized with a presumptive diagnosis of mechanical intestinal occlusion due to post-surgical bands and an exploratory laparotomy was performed, with a diagnostic finding of an inflamed Meckel's diverticulum. It was concluded with intestinal resection of the ileum segment. The patient evolved satisfactorily and was discharged on the eighth day after the intervention, without complications.

RESUMO

Resumen El divertículo de Meckel (DM) es el remanente del conducto onfalomesentérico y se considera la malformación congénita más común del tracto gastrointestinal. La mayoría de los pacientes son asintomáticos; sin embargo, aquellos en los que se desarrollan síntomas, estos pueden manifestarse como: dolor abdominal, hemorragia de tracto gastrointestinal, perforación u obstrucción intestinal. El objetivo de este reporte es presentar un caso de hernia interna secundaria a un divertículo de Meckel, siendo esta una causa poco frecuente de obstrucción intestinal.

Abstract Meckel's diverticulum is the remnant of the omphalomesenteric duct and is considered the most common congenital malformation of the gastrointestinal tract. Most patients are asymptomatic, however patients who develop symptoms can manifest: abdominal pain, gastrointestinal tract bleeding, intestinal perforation or obstruction. The objective of this report is to present a case of internal hernia secondary to a Meckel's diverticulum, a rare cause of bowel obstruction.

RESUMO

RESUMEN Presentamos el caso de una paciente de 50 años que consultó por dolor abdominal y síntomas de obstrucción intestinal. Se realizaron los estudios prequirúrgicos correspondientes y se decidió efectuar laparotomía exploradora, en la que se encontró divertículo de Meckel complicado por obstrucción de banda fibrosa.
