BACKGROUND: Laparoscopic Roux-en-Y gastric bypass (LRYGBP) can be technically challenging. It is imperative that patient morbidity and mortality are minimized while teams are on the learning curve for this procedure. METHODS: This retrospective study evaluated the peri-operative risk of LRYGBP utilizing a two-consultant surgeon approach in a newly established bariatric service. 100 consecutive patients undergoing LRYGBP were included. Two consultants participated in each procedure. RESULTS: Median operative duration was 113 minutes (range 80-240) and fell with increasing experience [127 minutes (range 90-240) in cases 1-50 and 105 minutes (range 80-210) in cases 51-100; P=0.009]. Multivariate analysis found operation time correlated only with number of procedures performed (P<0.001). There were no conversions to laparotomy. Intra-operatively, 2 patients had hand-assisted completion of the jejuno-jejunostomy, and 2 underwent laparoscopic revision of the reconstruction. Postoperative complications were observed in 8 patients on the operative admission. Median stay was 4 days (range 3-7). 4 patients required readmission. There was no mortality. Percentage of excess BMI loss was 47%, 53% and 70% at 3, 6 and 12 months respectively. CONCLUSION: A learning curve for LRYGBP is evidenced in this series by reduction in operative time with increasing experience. Complication rates in line with large published series can be achieved by adopting a two-surgeon approach, which we propose as a safe method to adopt in the development of new bariatric services.
