A Case of Mesodiverticular Band Causing Small Intestinal Obstruction

Abstract

Meckel's diverticulum is found in about 3% of the population, often incidentally during laparotomy or at autopsy. Over 50% of patients who develop symptoms from this anomaly are younger than 2 years of age. The most common symptom of this lesion is intestinal obstruction. Rarely Meckel's diverticulum is complicated by a mesodiverticular band, which is believed to be a remnant of a vitelline artery. We report a 11-year-old girl with small bowel obstruction because of an intestinal hernia beneath the mesodiverticular band. The causative factor was a stenotic area in the terminal ileum caused by a ringlike lipovascular mesenteric band encroaching externally on the lumen. Although the incidence of mesodiverticular bands complicating Meckel's diverticulum is quite low, the rapid clinical course and the associated high mortality rate make this an important disease.
