Perforated mesenteric Meckel's diverticulum: Case report

Perforated Meckel's Diverticulum as a Rare Cause of Pneumoperitoneum in a Post-pubescent Adolescent: A Case Report

Meckel's diverticulum (MD) is known to cause surgical emergencies including intussusception, obstruction, and bleeding, but rarely results in perforation with pneumoperitoneum. Symptomatic MD is rare but most commonly presents in early childhood. We report a case of a 17-year-old male who presented with peritonitis and radiographic imaging demonstrating pneumoperitoneum and inflammation near the appendix and terminal ileum. Intraoperative findings revealed a perforated MD. A perforated MD may mimic a diagnosis of complicated appendicitis in the adolescent and adult population and should be considered in the differential diagnosis of patients presenting with pneumoperitoneum and an acute surgical abdomen.

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.
