Introduction: Duodenal Crohn's disease requiring surgery has traditionally been managed with a bypass procedure. We compared our experience with duodenal strictureplasty with this traditional approach.

Methods: Records of patients operated on for duodenal Crohn's disease since 1980 were retrospectively reviewed. Patients having strictureplasty or bypass were compared with regard to demographics, indications, complications, and outcome.

Results: Since 1980, 34 patients were operated on for duodenal Crohn's disease. Mean age was 38.9 (range, 16-68) years, and 20 of 34 patients were females, with no significant differences between operative groups. Obstruction was the presenting symptom in 33 of 34 patients, and all had strictures. The basis for diagnosis of duodenal Crohn's disease was macroscopic appearance and the presence of Crohn's elsewhere in 29 of 34 patients, with only 5 of 34 having either duodenal or contiguous antral granulomas. Thirty-seven strictures were present in the 34 patients; 24 were in the proximal duodenum (8 strictureplasty, 16 bypass), 9 were in the midduodenum (4 strictureplasty, 5 bypass), and 4 were in the distal duodenum (3 strictureplasty, 1 bypass). Bypass was performed in 21 patients, with two operative complications, and at a mean follow-up of 8 years, 1 of 21 patients required reoperation for recurrent disease. Strictureplasty was performed in 13 patients, with two operative complication, and at a mean follow-up of 3.6 years, 1 patient required reoperation for recurrence also. Vagotomy was performed in 16 of 21 bypasses and 7 of 13 strictureplasties.

Conclusions: Although follow-up is shorter, strictureplasty is a safe and effective operation for duodenal Crohn's disease and should be considered when feasible.
