As a member of Univ. Doz. Dr. Gerhard Prager’s team for metabolic and bariatric surgery I have specialized in doing research on Sleeve gastrectomy, Omega Loop gastric bypass, as well as the treatment of weight regain after Roux-en-Y gastric bypass. My long-term study of Sleeve gastrectomy focusses reflux, weight regain, and quality of life. With my RCT on Omega Loop gastric bypass I aim at revealing the impact of anti-reflux sutures on biliary reflux after the procedure. I am also studying the outcome of different methods of treating weight regain (e.g. pouch resizing and banding) after Roux-en-Y gastric bypass.
Techniques, methods & infrastructure
- Retrospective database analyses
- Prospective clinical trials
- Prospective, randomized, controlled trial of Omega Loop Gastric Bypass with and without anti-reflux sutures – a pilot study (2017)
