Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to assess the safety and efficiency of OAGB compared to RYGB

Detailed Description

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

Rationale: to compare two different types of gastric bypass operations on surgical outcome.

Objective: to compare two established procedures in order to find the optimal procedure in terms of weight loss and metabolic control that is associated with the fewest side-effects and complications, and decreased invasiveness.

Study design: A multicentre, open label, non-inferiority randomized controlled trial Study population: Patients are eligible for inclusion if their body-mass index (BMI) was 40 kg/m2 or higher, or 35 kg/m2 or higher with the presence of at least one comorbidity (type 2 diabetes, high blood pressure, obstructive sleep apnoea, dyslipidaemia, osteoarthritis of the hip or knee) and a positive evaluation by our bariatric multidisciplinary team (BMDT) and are aged 18-65.

Intervention: Group 1: One Anastomosis Gastric Bypass with 150cm biliopancreatic limb. Group 2: Roux-en-Y gastric bypass with biliopancreatic limb of 150cm and 75cm alimentary limb.
