Ileo-Ileal Intussusception Caused by a Meckel's Diverticulum With Ectopic Pancreatic Tissue: A Case Report

A Meckel's diverticulum (MD) is an embryonic remnant of the omphalomesenteric duct. Although most MDs are usually asymptomatic, pediatric patients tend to present serious complications more frequently (4-25% of cases), mainly in digestive tract bleeding, intestinal obstruction, and perforation, which have a high potential to compromise the patient's life. An ectopic pancreas (EP) is pancreatic tissue found outside the pancreas, usually in the stomach, duodenum, and jejunum. It is typically asymptomatic but can increase the risk of complications in the MD. A clinical case of a female infant with an MD complicated with bleeding and ileo-ileal intussusception is presented, in which the histopathological finding of type 1 ectopic pancreatic tissue was also found based on the Heinrich classification, being an entity uncommon in our environment. An EP arising within an MD is infrequent, requiring clinical attention and timely preoperative diagnosis to prevent and treat associated severe complications. This continues to be a superior challenge for the clinician and requires a multidisciplinary team for comprehensive treatment.
