Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Nowadays morbid obesity (BMI ≥ 40kg/m²) is a major problem of public health in industrialized countries. About 500 000 patients would be affected by this disease in France in 2009. Prevalence of the morbid obesity raised from 0.3 % (± 0.1 %) of the population in 1997 to 1.1 % (± 0.1 %) in 2009 (Extrapolation of the data ObEpi on 2009 to the French population) (1). For this type of patient, the only long-term effective treatment recognized by the scientists is the bariatric surgery. (2-4) Roux and Y Gastric Bypass (GBP) is a consensual procedure, that has been described in the sixties, in this indication (approximately 11000 GBP performed in FRance in 2012 (5,6). This operation consists on the creation of a proximal gastric pouch (50 cc). A Roux and Y intestinal loop will be added to create a malabsorptive part. 60 to 80 % of excess weight loss described in the literature in the long-terms. Furthermore, improvement or remission of T2DM, sleep apnea syndrome, arterial hyperpressure, dyslipidemia) are emphasized in many trials (5, 7). However 15 to 20 % of the handled patients present a weight regain 5 years post surgery potentially explained by the dilation of the gastric pouch or the gastro jejunal anastomosis and thus a decrease of the restrictive effect. (8-11) To palliate this complication two solutions are described. (12-15; 19) The first one consists in a recalibration of the gastric poouch by surgical approachy. In this case, a ring of silicone or polypropylene can be positioned around the gastric pocket. Other possible solution is to redo a new gastrojejunostomy with a smaller size, by surgical access (laparotomy or laparoscopy). These interventions are very delicate because of important peritoneal adhesions and present a rate of significant morbidity especially if they are performed under laparotomy. The pure medical care does not allow long-term results stable. ²² A therapeutic dead end is reported often for this type of patient. A new possibility was recently described. (17-18) A recalibration can be realized by sutures performed under endoscopic approach at the level of the gastro jejunal anastomosis or from the gastric pouch by the APOLLO Endosurgery OverStitch. The digestive surgery by endoscopic way is rapidly expanding. The first results seem to be promising (resumed the weight loss) but owe to be estimated in a randomized study comparing this new process with the medical conventional treatment. A single-blind, randomized, forward-looking study, multicenter, comparative between two parallel groups of patients presenting a weight regain after GBP was thus organized. The main objective is to estimate the efficiency of the APOLLO Endosurgery OverStitch technique versus the non-interventional strategy. The secondary endpoints is to study the morbidity of the procedure, the evolution of quality of life of the patients, the medical economic impact of the innovation in 24 months.
