A Case of Endometrial Tissue Containing Meckel's Diverticulum in an Adult.

A Meckel's diverticulum is one of the most common congenital causes of small bowel obstruction. The lack of a more common gastric-containing tissue and older age of symptom onset can lead to difficulties with preoperative diagnosis. This case demonstrates an adult with chronic abdominal pain with recurrent small bowel obstruction that was found to be a rare ectopic endometrial tissue containing a Meckel's diverticulum following a diagnostic laparotomy. The barriers to diagnostics and factors affecting the age of onset are discussed with a focus on demonstrating the importance of surgical intervention for small bowel obstruction due to a Meckel's diverticulum and on the significance of a rare histological finding.
