RESUMO
Meckel diverticulum is the most common congenital anomaly of the gastrointestinal system. Although it is commonly asymptomatic in adults, Meckel diverticulum can lead to intussusception, volvulus, inflammatory adhesions, or an internal hernia. However, small bowel obstruction due to a mesodiverticular band of Meckel diverticulum is rare. We report a case of a 24-year-old man who complained of abdominal pain and vomiting caused by recurrent small bowel obstruction. He had undergone no previous abdominal surgery. Abdominal computed tomography revealed a transition point at the mid-to-distal ileum. To identify the cause of the obstruction, we performed single-balloon enteroscopy, which revealed extrinsic compression at the proximal ileum 100 cm from the ileocecal valve. After marking the obstruction site, subsequent laparoscopy revealed a Meckel diverticulum with a mesodiverticular band, which entrapped a bowel loop and caused the recurrent small bowel obstruction. The patient was treated successfully with laparoscopic diverticulectomy.
