  • Title: Subtotal duodenectomy with jejunal patch for megaduodenum secondary to congenital duodenal malformation.
    Author: Endo M, Ukiyama E, Yokoyama J, Kitajima M.
    Journal: J Pediatr Surg; 1998 Nov; 33(11):1636-40. PubMed ID: 9856883.
    Abstract:
    BACKGROUND/PURPOSE: This report describes a technique devised for two children with megaduodenum consisting of subtotal duodenal resection with the proximal jejunum used as an onlay patch. METHODS: A 2-year-old boy presented after unsuccessful surgical repairs for duodenal stenosis with web. Another 8-year-old boy returned from the United States after several surgical procedures for complicated congenital left diaphragmatic hernia with gastric outlet obstruction. Both boys manifested postprandial right upper abdominal fullness, occasional vomiting, abdominal pain, and failure to thrive. Upper gastrointestinal contrast study findings showed massively dilated duodenums in both patients that were larger than the stomach. During the operative procedures, about 95% of the duodenal wall was resected, leaving the basal portion that was unified with the pancreatic head and the ampulla of Vater as linguiform flap, which was covered with the proximal jejunum as an onlay patch so as to form the anterior wall of the duodenal bulb. RESULTS: The patients showed markedly improved quality of life and catch-up growth after the operations. The duodenal bulbs were of adequate size in follow-up gastrointestinal series. CONCLUSION: This technique will be useful in cases of functional duodenal obstruction with megaduodenum secondary to congenital duodenal malformations leading to blind loop syndrome.
