The omphalomesenteric duct normally obliterates by the sixth week of intrauterine life. Incomplete obliteration results various abnormalities which may be apparent in the newborn infant. The omphalomesenteric duct may persist as an omphalomesenteric fistula. Morphologically the fistula resembles the ileum, but may contain ectopic gastric, colonic or pancreatic tissue. The infant presents with an umbilical discharge which may be recognizable as small bowel content. Although this malforamtion 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 experienced 4 cases of patent omphalomesenteric duct remnant including one case of T-shaped total prolapse of duct and adjacent ileum. These cases will be discussed with literature review.

Meckel's diverticulum is the most common congenital anomaly that results from an incomplete obliteration of omphalomesenteric duct. But only 10% of Meckel's diverticulums are symptomatic. The most common presentation in children is painless rectal bleeding, while intestinal obstruction is more common in adults. Obstruction with a Meckel's diverticulum is usually attributed to intussusception, volvulus, inflammatory adhesion, or an internal hernia. Author's experienced multi-directionally rotated Meckel's diverticulum causes intestinal obstruction with gangrenous change in a child and removed successfully with laparoscopic assistance. To our knowledge, this appears to be a first case report of a torsion of Meckel's diverticulum associated with intestinal obstruction in Korea, which was treated by laparoscopic procedure.

Two cases with umbilical polyp are reported. One was 7-year-old boy who had l. 5cm x l. 6cm protruded urnbilieal growth, the other was 2-year-old baby who had 0. 7crn x 0. 6cm umbilical growth. This uncommon malforrnation arises from remnants of the omphalomesenteric duct and should be clinically discerned from a granuloma pyogenicum or other benign umbilical neoplasms. Histllogically umbilical polyp shows blanching glandular structures lined by intestinaI mucosa in connection with the surface of the skin. When the umbilical polyp is not associated with any other types of underlying abnormalities, it may be treated by a simple surgical excision.

Of 72 cases with vitelline duct and vessel remnants, 45 (62.5%) had symptomatic lesions (mean age, 27.9 months) with male preponderance (4.6: 1). Among the 45 symptomatic lesions, there were 22 cases of Meckel's diverticulum, 6 cases of Meckel's diverticulum with fibrous band attached to the umbilicus, 6 cases of patent vitelline duct, 5 cases of vitelline artery remnant as fibrous band, 2 cases of umbilical sinus, 2 cases of umbilical polyp, and 2 cases of vitelline cyst. Twenty three cases (51%) presented with intestinal obstruction, 6 (13%) with rectal bleeding, 4 (9%) with perforated Meckel's diverticulum, 5 with intestinal fluid drainage through umbilicus, 5 with umbilical lesion, and 1 with abdominal mass. Intestinal obstruction due to fibrous band developed at infancy (average age, 4.6 months). About 82% of complicated Meckel's diverticulum (n=28) presented less than 4 years of age. Seventeen Meckel's diverticulums, 8 obliterated vitelline artery remnants, and 1 vitelline vein remnant as fibrous band were found incidentally at laparotomy.

Meckel's diverticulum (MD) is a true congenital diverticulum that is remnant by incomplete obliteration of the omphalomesenteric duct. It is the most common congenital anomaly of the gastrointestinal tract, with an estimated prevalence of 2% (0.3% to 3% in autopsy studies). About 90% of MD occurs within 100 cm of the ileocecal valve. A primary malignant tumor arising within an MD is extremely uncommon. Malignancies are reported to account for only 0.5% to 3.2% of the complications. Carcinoids are the most common malignant tumors occurring in MD. Adenocarcinomas are extremely uncommon and very poor prognosis has been reported. We report a case of radiographically diagnosed chronic inflammatory mass caused by adenocarcinoma arising from MD in the ileum with malrotation of the midgut incidentally discovered at exploration.

The vitelline duct is the primitive connection between the yolk sac and embryonic midgut, and undergoes involution between the seventh and ninth weeks of fetal development. A patent omphalomesenteric duct is a form of umbilical remnant with a communication between the umbilicus and intestine that requires surgical resection. Completely patent omphalomesenteric duct is very rare. We here report a case of intestinal obstruction with small bowel strangulation caused by patent omphalomesenteric duct in a 33-year-old man.
