Clinical Trial Summary

Morbid obesity is an increasing medical problem in the western countries. It's related to comorbidities as diabetes mellitus, hypertension, OSAS, arthrosis and hypercholesterolemia. The Roux-en-Y Gastric Bypass (RYGB) is an effective surgical therapy for morbidly obese patients. A part of these patients will have disappointing results, and have weight regain on the long term. Some studies show more weight reduction by increasing the biliopancreatic limb in patients with morbid obesity.

The objective of this study is to investigate the effect of a restrictive/extended pouch on weight reduction in morbidly obese patients undergoing RYGB-surgery. We hypothesize that the restrictive/extended pouch results in more weight reduction.

The study design is a prospective, randomized control trial. The patients will be randomized in 2 groups: a standard RYGB (normal pouch) and restrictive/extended pouch RYGB.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Complications	Complications will be divided in short-term complications (within 30 days after operation) and long-term complications (after 30 days). All adverse event will be registered.	2 years
Other	Quality of life	The quality of life will be assessed by using the BAROS.	2 years
Primary	Weight reduction	Excess weight loss (%EWL)	2 years
Secondary	Change in comorbidities	Preoperatively the number of patients with comorbidities will be calculated. At two year follow-up this will be calculated again. Patients will be divided in groups: comorbidity resolved; comorbidity improved; comorbidity unchanged; comorbidity worsened; This will be done for diabetes mellitus, hypertension, dyslipidemia and OSAS.	2 years
Secondary	Change in comorbidities	Preoperatively the number of patients with comorbidities will be calculated. At two year follow-up this will be calculated again. Patients will be divided in groups: comorbidity resolved; comorbidity improved; comorbidity unchanged; comorbidity worsened; This will be done for diabetes mellitus, hypertension, dislipidemia and OSAS.	2 years
