Cecal volvulus secondary to mesodiverticular band.

Meckel's diverticula are one of the most common gastrointestinal anomalies, yet mesodiverticular bands are rare. The treatment of these bands commonly requires surgery. A healthy patient in his 20s presented to the emergency department with a 1 day history of acute onset abdominal pain. Computed tomography imaging was consistent with volvulus of the large intestine. In the operating room, the patient was noted to have a band between the ileal mesentery and tip of a Meckel's diverticulum, consistent with a mesodivertiular band, through which cecum had volvulized. The patient underwent resection. The patient recovered without major complications. Mesodiverticular bands are rare, but may present as hemoperitoneum, small bowel obstruction, or volvulus. Pre-operative diagnosis of a mesodiverticular band is often difficult and they are most commonly diagnosed intraoperatively. Treatment should include surgery and may include simple lysis of the band, bowel resection, or more extensive resection if other pathology is present.
