Abstract
BACKGROUND
One limit of the Roux-en-Y gastric bypass (GBP) is the preclusion of exploring the bypassed stomach with conventional endoscopy and radiological studies. In this study, we explored the feasibility, safety, and weight progression of a new bariatric procedure that eliminates this inconvenience.
METHODS
Eleven 40- to 50-kg Yorkshire pigs underwent laparoscopic sleeve gastrectomy and Roux-en-Y duodeno-jejunal bypass (SG-DJBP). Weight was monitored at postoperative days 15 and 30 and after 3 months; weight progression was compared with an identical group that underwent a sham procedure or GBP. At autopsy, surgical site was evaluated at microscopic and macroscopic level.
RESULTS
Mean operating time was 66 +/- 5.76 min. All the survivors tolerated the procedure well, except one subject that experienced a gastric leak from the stapler line. The SG-DJBP had a had significantly slower weight gains than the sham group (P = 0.005). The absence of histological abnormalities in the duodenal wall was confirmed at autopsy.
CONCLUSION
SG-DJBP is feasible and produces effects of weight progression comparable to those of GBP. Being a combination of previously standardized procedures, we are confident to propose this procedure as a bariatric alternative in humans. Long-term follow-up will be required to establish the efficacy on weight loss in humans.
