Tapering duodenoplasty: a beneficial adjunct in the treatment of congenital duodenal obstruction

Abstract

Objective: Congenital duodenal obstruction is typically treated by duodenoduodenostomy. Tapering of the dilated segment has been indicated to reduce duodenal dysmotility. The purpose of this study was to review the outcomes between these two approaches. Methods: We retrospectively reviewed cases of duodenal obstruction repair performed at a quaternary care referral pediatric hospital from 2007 to 2017. The length of stay, time to full enteral feeding, and complications were compared between patients who underwent duodenoduodenostomy with and without tapering duodenoplasty (n=4 and n=35, respectively). Results: Both groups had similar times to initial enteral feeding (7 days) and full enteral feeding (14 vs. 15 days). Among the 35 patients who underwent duodenoduodenostomy alone, 6 (17%) required a return to the operating room; in contrast, no patients who underwent tapering required a return to the operating room. Of those who returned to the operating room, two underwent tapering at that time because of duodenal dilation and feeding intolerance. Conclusions: Although limited by the small sample size, this study suggests that patients undergoing tapering duodenoplasty may have a slightly shorter time to full enteral feeding and a lower rate of complications than patients undergoing duodenoduodenostomy alone.
