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.
