Strangulated internal hernia via a congenital posterior gastric antral mesenteric defect in an adolescent: a rare case report and literature review

Emergency physicians should maintain a high index of suspicion for transmesenteric hernia as a potential cause of acute strangulation and bowel necrosis in patients presenting with acute abdomen, and timely surgical intervention is essential. Although long-term outcomes require further evaluation, ileal resection near the ileocecal region with preservation of the valve using a side-to-side anastomosis may represent a salvage strategy under high-risk anatomical conditions.
