Complications associated with surgical treatment of congenital intrinsic duodenal obstruction.
Although survival rates for infants undergoing surgical treatment for congenital intrinsic duodenal obstruction are high, long-term follow-up suggests a high complication rate related to surgical therapy. We reviewed 33 neonates who underwent surgery for congenital intrinsic duodenal obstruction during the past 10 years. There were 20 girls and 13 boys; the mean gestational age was 36 weeks, and mean birthweight was 2,485 g. Bilious vomiting and intestinal obstruction were the most frequent presenting symptoms. Hydramnios was present in 75% of cases and 21% had associated Down's syndrome. Findings at laparotomy included duodenal atresia (14), annular pancreas (11), and duodenal diaphragm (8). The most frequent surgical procedure was side-to-side duodenoduodenostomy (DD), followed by duodenojejunostomy and resection of web with Heineke-Mikulicz type duodenoplasty. Bowel transit was reestablished at a mean of 13.1 days (range, 6 to 45 days). Seventy-percent of patients developed postoperative complications, the most frequent being megaduodenum with blind loop syndrome or bile reflux gastritis (22%), cholestatic jaundice (17%), gastroesophageal reflux (17%), delayed transit (8%), and bowel obstruction (8%). Six patients (18%) required secondary surgical procedures for postoperative complications (ie, megaduodenum, nonfunctioning anastomosis, missed intrinsic stenosis). Two patients died (6%). Stagnation and functional obstruction in the proximal duodenum is the main factor influencing the morbidity rate among these patients. Consideration should be given to the tapering duodenoplasty and diamond-shaped anastomosis in order to help reduce problems associated with megaduodenum and help restore earlier bowel transit.
