Complicated Meckel's diverticulum due to axial torsion and fibrous band formation: a rare cause of acute abdomen.

Acute abdomen is a potentially life-threatening condition requiring prompt evaluation and surgical intervention. Symptomatic Meckel's diverticulum in adults is uncommon and may mimic other intra-abdominal pathologies. We report a 25-year-old man presenting with diffuse abdominal pain, nausea, diarrhea, and signs of peritoneal irritation suggestive of complicated appendicitis. Exploratory laparotomy revealed axial torsion of a Meckel's diverticulum with irreversible vascular compromise caused by a fibrous band. Diverticulectomy with wedge resection was performed, resulting in complete recovery. This case highlights the diagnostic challenge of complicated Meckel's diverticulum and the importance of considering rare causes of acute abdomen.
