Laparoscopic versus open treatment of congenital duodenal obstruction: multicenter short-term outcomes analysis.

BACKGROUND: Laparoscopic repair of congenital duodenal obstruction has become popularized over the past decade. Comparative data on outcomes, however, are sparse. We hypothesized that laparoscopic repair of congenital duodenal obstruction could be performed with similar outcomes to traditional open repair. PATIENTS AND METHODS: Medical records for all cases of congenital duodenal obstruction from 2005 to 2011 at three academic teaching hospitals were retrospectively reviewed. Patients were excluded from the analysis if they had confounding surgical diseases, did not have duodenoduodenostomy during the first hospital admission, had the repair performed before transfer from a referring hospital, or weighed less than 1.7  kg at the time of surgery. Analysis was performed as intention to treat, with laparoscopic converted to open cases included in the laparoscopic group.
RESULTS: Sixty-four cases were included in the analysis (44 open, 20 laparoscopic). Baseline characteristics were similar between the two groups with the exception that the open group, on average, underwent repair later than the laparoscopic group (6 days versus 4 days, respectively). Seven laparoscopic cases were converted to an open procedure (35%), most commonly for difficulty in exposing the decompressed distal duodenum. Laparoscopic repair did take significantly longer than open repair (145 minutes versus 96 minutes, respectively), but clinical outcomes were similar. Complications were rare and were similar between methods of repair. Two patients in the laparoscopic group required subsequent open revision.
CONCLUSIONS: Laparoscopic duodenoduodenostomy for congenital duodenal obstruction is a technically challenging procedure with a steep learning curve. Despite a relatively high conversion rate, clinical outcomes remained similar to the traditional open repair in selected patients.
