Effects of Long Biliopancreatic Limb vs. Long Alimentary Limb in Superobesity, a Randomized Study

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.
Verified March 2015 by Aleris Obesity.
Recruitment status was:  Recruiting

Super Obesity, i.e. a BMI above 50, is difficult to treat. Normal gastric bypass surgery is not always enough. 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 proximal (oral) portion of the jejunum from food contact with the effects when preventing the jejunum from contact with bile and pancreatic juice.

Endpoints are quality of life, gstrointestinal function, and weight development.

Further study details as provided by Aleris Obesity:

Primary Outcome Measures:
  • body weight reduction [ Time Frame: 2 years ]
    absolute BW reduction, percentage of patients reaching BMI below 30,

Secondary Outcome Measures:
  • gastrointestinal function [ Time Frame: 2 years ]
    SF-36, Op-9, GSRS and TFEQ are used in patient assessed variables

Estimated Enrollment: 200
Study Start Date: June 2011
Estimated Study Completion Date: June 2016
Estimated Primary Completion Date: June 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: standard length bp limb, long alimentary limb
our normal way of doing a gastric bypass
Procedure: gastric bypass
two techniques of gastric bypass for studying the effects of making a long BP-limb
Experimental: Long BP limb Procedure: gastric bypass
two techniques of gastric bypass for studying the effects of making a long BP-limb

Detailed Description:

Two variations of gastric bypass are compared:

Method 1:A 200 cm BP-limb (distance Treitz to EA)+ 150 cm common channel (EA to ileocecal valve) + Roux-Y-limb variable Method 2: 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.
