Mesodiverticular Band of Meckel's Diverticulum as a Rare Cause of Small Bowel Obstruction: Case Report and Review of the Literature

Abstract

Background: Meckel's diverticulum, which was first described by Johann Friedrich Meckel, is a congenital anomaly. It results from incomplete obliteration of the most proximal portion of the vitelline or omphalomesenteric duct. Its prevalence is ranging from 1 to 4% of the population. The lifetime risk of complications is estimated at 4-6%. One of them is intestinal obstruction which is a more common presentation among adults. Mesodiverticular band, as presented in this case report, is a rare cause of small bowel obstruction in Meckel's diverticulum. Case Report: We report the case of a 17-year-old male who had intestinal obstruction caused by a mesodiverticular band of Meckel's diverticulum. He presented with severe abdominal pain, nausea, and vomiting. The established diagnosis was mechanical intestinal obstruction. Laparotomy revealed an internal herniation and obstruction caused by a mesodiverticular band of Meckel's diverticulum. There was no evidence of necrosis or ischemia. The mesodiverticular band was released from the ileal mesentery and the Meckel's diverticulum was resected. The postoperative period was uneventful and the patient was discharged after 6 days. Conclusion: The incidence of an internal hernia caused by a mesodiverticular band of Meckel's diverticulum is rare. It may be overlooked in the case of intestinal obstruction because of nonspecific symptoms. Delay in the diagnosis can lead to significant morbidity and mortality. In the case of small bowel obstruction, Meckel's diverticulum should therefore be kept in mind.
