Official title

A Multicentre Randomized Controlled Trial Comparing Outcome of Laparoscopic One-anastomosis Gastric Bypass and Laparoscopic Long Biliopancreatic Limb Roux Gastric Bypass for Treatment of Morbid Obesity.

Overview

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.

Interventions

  • Procedure One-anastomosis gastric bypass
    One group is planned to have one-anastomosis gastric bypass (also known as mini-bypass)
  • Procedure Long biliary limb Roux gastric bypass
    Other group is planned to receive a long biliary limb Roux gastric bypass

Primary outcome measures

  • Excess weight loss % [Time frame: 10 years]
  • Impact on type 2 diabetes mellitus [Time frame: 10 years]
  • Impact on type 2 diabetes mellitus [Time frame: 10 years]
  • Impact on hypertensive disease [Time frame: 10 years]
  • Impact on total cholesterol [Time frame: 10 years]
  • Impact on hyperlipidemia [Time frame: 10 years]
  • Impact on hyperlipidemia [Time frame: 10 years]
  • Impact on hyperlipidemia [Time frame: 10 years]
  • Impact on hyperlipidemias [Time frame: 10 years]
Secondary outcome measures (3)
  • Nutritional deficiencies: anemia [Time frame: 10 years]
  • Nutritional deficiencies [Time frame: 10 years]
  • GERD [Time frame: 10 years]
