RCT Comparing OAGB and Long Limb Roux Gastric Bypass
RCT Comparing OAGB and Long Limb Roux Gastric Bypass
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.
