Background
Laparoscopic Roux en-Y gastric bypass (LRYGB) achieves sustained long-term weight loss and reduced mortality in morbidly obese patients. It is routinely performed using an ante- or retrocolic approach with the jejuno-jejunostomy constructed in the infracolic compartment. We have modified the standard technique of performing LRYGB by constructing both anastomoses in the supracolic compartment. This study describes the outcomes of consecutive primary LRYGB performed using this novel retrocolic–supracolic approach.
Methods
Data were prospectively collected on consecutive primary LRYGB performed in a tertiary-referral Bariatric Centre in the United Kingdom from September 2009 to March 2013. Data included demographics, operative outcomes (duration of surgery, postoperative anastomotic leak/bleeding/reoperations), development of strictures, length of stay, excess weight loss (EWL) and resolution of diabetes mellitus.
Results
Hand-sewn LRYGB was successfully performed using the retrocolic–supracolic approach in 300 of 307 (98 %) consecutive patients (72 % female). Median (IQR) age, weight and baseline body mass index were 49 (41–56) years, 146 (134–163) kg and 52.9 (48.8–57.2) kg/m2, respectively. There were 4 (1.3 %) anastomotic leaks and 8 (2.6 %) postoperative bleeds. The 30-day reoperation rate was 1.6 %. Median (IQR) hospital stay was 2 (2–2) days. Postoperative dysphagia requiring endoscopic balloon dilatation occurred in 19 (6.3 %) patients. Mean ± SD 12-month EWL was 69.9 ± 19.0 %. Within the follow-up period, 81 % of patients with type II diabetes mellitus achieved remission and 19 % reduced dosage of diabetes medication.
Conclusions
LRYGB performed using the retrocolic–supracolic approach was safe, feasible, technically advantageous and resulted in clinical outcomes akin to the standard infracolic approach.
