About this trial
This study is designed as a prospective multicenter randomized controlled clinical trial comparing two surgical techniques of distal gastric bypass (DGB) in revisional surgery following failed Roux-en-Y gastric bypass. Patients will be randomly allocated 1:1 to A) DGB with lengthening of the BPL (DGB type I) or B) DGB with extended AL (DGB type II). Randomisation is stratified for participating center. The study will be performed in a clinical and out-patient setting with regular visits at 1.5, 3, 6, 12, 18, 24 and 36 months post intervention. The study will be set up as a multicenter study with bariatric centers: St. Antonius hospital, Groene Hart hospital, OLVG, Rijnstate hospital, Elisabeth Twee-steden Hospital, Bravis hospital, Medisch Centrum Leeuwarden, Catharina Hospital.
