Abstract
From 1975 to September 1986, 12 pediatric patients (5 males and 7 females) with omphalomesenteric duct remnants have been admitted to the Department of Pediatric Surgery, Hiroshima Prefectural Hospital. The anomalies include 2 patent omphalomesenteric duct, 2 umbilical sinus, one vitelline cyst, and 7 Meckel's diverticulum. Six of them were diagnosed in neonates. One of the 2 patients with patent omphalomesenteric duct had ileal prolapse during the conservative therapy, and the other was diagnosed by fistelography. The diagnosis of umbilical sinus was difficult. Their preoperative diagnosis was umbilical granuloma. The final diagnosis was made by the operative findings and histology. The diagnosis of vitelline cyst was also established by the histology. In all of 12 patients, surgical excision was performed and good results were obtained in 10 patients. Two neonates with the perforation of Meckel's diverticulum, however, were in serious condition at the time of operation and died of sepsis.
