Brief Summary

Background and study aims: Currently, one anastomosis Gastric Bypass (OAGB) is a common bariatric procedure. Obesity and 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 for GERD patients OAGB procedures only with hiatus cruroraphy is performed. The goal of this randomized controlled clinical trial is to compare bariatric and antireflux results after OAGB plus suture cruroplasty with FundoRing (n=50) versus Nissen fundoplication (n=50) and versus without total fundoplication (n=50) for patients with morbid obesity and GERD. The main questions it aims to answer are:

  • What is the impact of wrapping the fundus of the excluded part of the stomach use FundoRing method in the experimental group against developing reflux esophagitis compare impact standard Nissen in OAGB?
  • What is the impact of excluded stomach fundoplication on weight loss in FundoRing group versus standard Nissen group in OAGB? Methods: Adult participants (n=150) are randomly allocated to one of three groups: Experimental surgical bariatric procedure in the first (A) group: patients (n=50) undergo the laparoscopic one anastomosis gastric bypass with excluded stomach fundoplication: FundoRingOAGB and suture cruroplasty (OAGB + SCP + FundoRing); Active comparator surgical bariatric procedure in the second (B) group: patients (n=50) undergo the laparoscopic one anastomosis gastric bypass with excluded stomach Nissen fundoplication and suture cruroplasty (OAGB + SCP +NF). Active comparator surgical bariatric procedure in the second (C) group: patients (n=50) undergo laparoscopic one anastomosis gastric bypass without excluded stomach fundoplication and only suture cruroplasty (OAGB + SCP). All patients are then followed up 12, 24, and 36 months after surgery where the changing body mass index and change of GERD symptoms (GERD-HRQL).

Outcome Measures

Primary Outcomes (2)

  • Change of body mass index

    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.

    Baseline, at 12, 24, 36 months after surgery

  • Change of GERD symptoms (GERD-HRQL)

    Success; ≥50% improvement in the baseline GERD-HRQL score Failure; \<50% improvement in the baseline GERD-HRQL score at 12,24, 36 months.

    12, 24, 36 months after surgery
