Clinical Trial Summary

A prospective multicenter randomized controlled trial to compare the outcomes of one-anastomosis gastric bypass to long biliary limb Roux gastric bypass. We plan to enroll up to 500 patients from three different clinics in Estonia. Outcomes are excess weight loss %, impact on type 2 diabetes, hypertension, hyperlipidemia and obstructive sleep apnea. Other outcomes are nutritional deficiencies, occurrence of reflux disease and impact on quality of life. There are planned outpatient visits 1, 5 and 10 years after the surgery to measure the impacts. There are a lot of studies comparing OAGB to standard Roux gastric bypass but non comparing it to long biliary limb gastric bypass.
