Perforated Meckel’s diverticulum as a result of gastrointestinal stromal tumor presenting as acute abdomen: A rare case report
Meckel’s diverticulum is present on the antimesentric border of the terminal ileum, within 2 ft proximal to the ileocecal valve, and results from incomplete closure of the vitello‑intestinal duct. Meckel’s diverticulum is usually diagnosed during laparotomy or due to a complication of it such as bleeding, diverticulitis, and perforation. Tumors within Meckel’s diverticulum are a rare, but known complication. A 50‑year‑old male presented with fever and pain abdomen particularly in periumbilical region with sign of peritonitis. During laparotomy, a perforated Meckel’s diverticulum was found. A perforation was found at the apex of Meckel’s diverticulum. We resected 5 cm of the healthy bowel each side with primary anastomosis. Histopathology and immune‑histochemistry shows gastrointestinal stromal tumors (GISTs) of Meckel’s diverticulum. GISTs arising from Meckel’s diverticulum are an extremely rare, but recognized complication. Surgery is the standard treatment for nonmetastatic GISTs with en bloc resection and clear margins.
