A case of intestinal obstruction caused by a mesodiverticular band in Meckel's diverticulum with ectopic pancreas treated by laparoscopic surgery

INTRODUCTION: We report a case of a patient who underwent laparoscopic surgery for intestinal obstruction caused by the mesodiverticular band of Meckel's diverticulum, with pathological specimens showing ectopic pancreas. PRESENTATION OF CASE: A 56-year-old woman presented to our hospital with complaints of abdominal pain and vomiting. Upon close examination, we suspected strangulated intestinal obstruction, and performed an emergency surgery. An internal hernia with a band leading to a Meckel's diverticulum was noted. Focusing on the attachment of the band, leading to the Meckel's diverticulum, we suspected a mesodiverticular band and deemed it necessary to be resected. Surgery was completed with resection of the band to relieve the intestinal obstruction, with simultaneous resection of the Meckel's diverticulum. It was necessary to resect Meckel's diverticulum simultaneously for histopathological examination. Histopathological examination revealed a mesodiverticular band in the resected band and ectopic pancreas in the Meckel's diverticulum. DISCUSSION: We chose to perform a complete laparoscopic resection because of the presence of simple intestinal obstruction caused by mesodiverticular bands or diverticula. We believe that small laparotomy can be opted in less severe cases, regardless of laparoscopic completion. CONCLUSION: We suspected adherent bowel obstruction and detected a band. We focused on band attachment and determined that the band should be resected if it was attached to Meckel's diverticulum. The resection method should be carefully selected, and the specimen should be histopathalogically examined.
