Totally Robotic Reversal of Omega-Loop Gastric Bypass to Normal Anatomy
Abstract
BACKGROUND: Gastric bypass procedures can potentially lead to middle and long-term complications (Podnos et al. Arch Surg 138(9):957-61, 2003). For several years, Roux-en-Y gastric bypass reversal procedures performed by laparotomy or laparoscopic way have been described in literature (Moon et al. Surg Obes Relat Dis 11(4):821-6, 2015). Major complications are anastomotic ulcers, anastomotic complications or functional disorder such as dumping syndrome, hypocalcemia, severe hypoglycemia, and malnutrition (Moon et al. Surg Obes Relat Dis 11(4):821-6, 2015; Campos et al. Surg Obes Relat Dis 10(1):36-43, 2014). One-anastomosis gastric bypass (OAGB) also called omega-loop gastric bypass (OLGB) or mini-gastric bypass (MGB) is a technique that has demonstrated similar results to traditional Roux-en-Y procedures in terms of weight loss and postoperative quality of life (Lee et al. Ann Surg 242(1):20-8, 2005). However, in a recent description of 1000 patients, the percentage of malnutrition was 0.2 % (two patients) with an indication to revert omega-loop gastric bypass back into normal anatomy (Chevallier et al. Obes Surg 25(6):951-8, 2015), but technical details have not been exposed yet. The first robotic gastric bypass was published by Horgan and Vanuno in 2001 (Horgan and Vanuno J Laparoendosc Adv Surg Tech A 11(6):415-9, 2001). The present work describes for the first time a robotic procedure to reverse OLGB into normal anatomy.

How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health. Reported size: 1,000 participants or records.
