The omphalomesenteric duct normally obliterates by the sixth week of intrauterine life. Incomplete obliteration results in various abnormalities which may be apparent in the newborn infant. These include fistula resembling ileum, a prolapsed loop of intestine through the umblicus and a fistula draining intestinal contents. The tract may contain ectopic tissue of stomach, colon or pancreas. Although this malformation should be recognizable at birth, 40 % of patients are not treated until after the first month of life. In the past 28 months since the Samsung Medical Center opened its doors to public, the authors have treated 4 cases of patent omphalomesenteric duct remnant including one case of T-shaped total prolapse of the duct and adjacent ileum. These cases will be discussed and the literature reviewed.

Of 72 patients with vitelline duct and vessel remnants, 45 (62.5 %) had symptomatic lesions. The mean age of the patients was 27.9 months. Males predominated (4.6 : 1). There were 22 cases of Meckel's diverticulum, 6 of Meckel's diverticulum attatched to the umbilicus with a fibrous band, 6 cases of patent vitelline duct, 5 cases of vitelline artery remnants as a fibrous band and 2 cases each of umbilical sinus and polyp, and vitelline cyst. Twenty-three patients (51 %) presented with intestinal obstruction, 6(13 %) with rectal bleeding, 4(9 %) with perforated Meckel's diverticulum, 5 with intestinal juice drainage through umbilicus, 5 with umbilical lesions, 1 with abdominal mass, and 1 with sepsis. Intestinal obstruction due to fibrous band developed during infancy(average age; 4.6 months). Seventeen asymptomatic Meckel's diverticulum, 8 obliterated vitelline artery remnants and 1 vitelline vein remnant as fibrous band, and 1 vitelline cyst were found incidentally at laparotomy. About 82 % of the complicated Meckel's diverticulum presented in infants and children less than 4 years of age.

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.
