Weight gain after surgery is a big problem in bariatric practice. Therefore, adjustable bands and rings are used, for example, "FobiRing". But foreign material can cause complications - the erosion of the stomach wall. For this reason, surgeons avoid the use of various mechanical devices on living tissues.\n\nThe greatest criticism is of the OAGB for the likelihood of biliary reflux. In case of reflux of bile into the esophagus after surgery, as a rule, a second operation is required with conversion OAGB to the Roux-en-Y method.\n\nIn addition, along with obesity, gastroesophageal reflux disease (GERD) are steadily increasing world weight and antireflux surgery must be performed simultaneously with bariatric surgery in obese patients. In these cases, most often in bariatric practice, hiatus cruroraphy is performed, and less often fundoplication using the fundus of the excluded part of the stomach.\n\nWe hypothesize that total fundoplication can not only treat GERD but also significant prevent the return of weight like after a banded gastric bypass and prevent postoperative bile reflux in the esophagus.\n\nThe aim study is to compare primary outcome as weight loss after total wrapping of the fundus of the gastric excluded part (FundoRing) and non - wrapping (non - banded) standard method of laparoscopic one anastomosis gastric bypass and measure secondary outcome: bile reflux in the esophagus and GERD symptoms.\n\nMethods: Adult participants (n=1000) are randomly allocated to one of two groups:\n\nExperimental surgical bariatric procedure in the first (A) group: patients (n=500) undergo the laparoscopic one anastomosis gastric bypass with the total wrapping of the fundus of gastric excluded part and suture cruroplasty if present hiatal hernia (FundoRingOAGB group); Active comparator surgical bariatric procedure in the second (B) group: patients (n=500) undergo the laparoscopic one anastomosis gastric bypass and with only suture cruroplasty if present hiatal hernia (OAGB group).', 'detailedDescription': 'One anastomosis Gastric Bypass/Mini Gastric Bypass (OAGB/MGB) is gaining popularity as a primary surgical treatment for morbid obesity.\n\nThe aim study is to compare primary outcome as weight loss after total wrapping of the fundus of the gastric excluded part (FundoRing) and non - wrapping (non - banded) standard method of laparoscopic one anastomosis gastric bypass and measure secondary outcome: bile reflux in the esophagus and GERD symptoms.\n\nMethods: Adult participants (n=1000) are randomly allocated to one of two groups:\n\nExperimental surgical bariatric procedure in the first (A) group: patients (n=500) undergo the laparoscopic one anastomosis gastric bypass with the total wrapping of the fundus of gastric excluded part and suture cruroplasty if present hiatal hernia (FundoRingOAGB group); Active comparator surgical bariatric procedure in the second (B) group: patients (n=500) undergo the laparoscopic one anastomosis gastric bypass and with only suture cruroplasty if present hiatal hernia (OAGB group).
