The FundoRingOAGB Versus Non-wrapping (Non-banded) Standard Method of Laparoscopic One Anastomosis Gastric Bypass
- Conditions
- Obesity, Morbid
- Registration Number
- NCT04834635
- Lead Sponsor
- The Society of Bariatric and Metabolic Surgeons of Kazakhstan
- Brief Summary
Currently, one anastomosis gastric bypass (OAGB) or mini-gastric bypass (MGB) is a common bariatric procedure for treating obesity. 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.
The 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.
In 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.
We 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.
The 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.
Methods: Adult participants (n=1000) are randomly allocated to one of two groups:
Experimental 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).
- Detailed Description
One anastomosis Gastric Bypass/Mini Gastric Bypass (OAGB/MGB) is gaining popularity as a primary surgical treatment for morbid obesity.
The 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.
Methods: Adult participants (n=1000) are randomly allocated to one of two groups:
Experimental 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). All patients are then followed up 12, 24, 36 months after surgery where record the changing body mass index and and measure secondary outcome: bile reflux in the esophagus and GERD symptoms.

Name Time Method Change of body mass index Baseline, at 12, 24, 36 months after surgery The measure is assessing a change of body mass index. Weight (kg) and height (cm) will be combined with the report of measurement by body mass index (BMI) kg/m2.
- Secondary Outcome Measures
Name Time Method Postoperative bile reflux in esophagus at 12, 24, 36 months after surgery The endoscopic finding of postoperative bile reflux in the esophagus
GERD symptoms Baseline, 12, 24, 36 months after surgery Change og GERD symptoms if present GERD or postoperative de Novo GERD symptoms (GERD-HRQL)
Oral glucose tolerance tests Blood samples for glucose collects at 0, 15, 30, 60, 120, 150 and 180 minutes, while those for insulin collects at 0, 30, 60, 120 and 180 minutes A 3-hour oral glucose tolerance tests performs using 75 g glucose
Sigstad score 6, 12, 24, 36 months after surgery Sigstad score for questionnaire of diagnostic the dumping syndrome
