Super Obesity, i.e. a BMI above 50, is difficult to treat. Normal gastric bypass surgery is not always enough for proper weight control. Bypassing a longer segment of the gut may be more beneficial. Which part to bypass is not clear. The investigators want to compare the effects between preventing a 60 cm proximal (oral) portion of the jejunum from food contact with the effects when preventing a 200 cm part of the jejunum from contact with bile and pancreatic juice. Endpoints are quality of life, gastrointestinal function, and weight development.
Two variations of gastric bypass are compared: Method 1 (test method):A 200 cm BP-limb (distance Treitz to EA) + 150 cm common channel (EA to ileocecal valve) + Roux-Y-limb variable Method 2 (standard method): A 60 cm BP limb + 150 cm Roux-Y-limb + common channel variable. Patients are evaluated according to the principles of the Scandinavian Obesity surgery registry (SOReg) with the addition of two additional questionnaires. FU time is set at 5 years.
