Обзор
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.
Подробное описание
Rationale: Up to 35% of morbidly obese patients undergoing Roux-en-Y gastric bypass (RYGB) fail to lose sufficient weight or regain excessive weight after initial weight loss. Currently, there is no standardized approach to revisional surgery after failed RYGB. Distalisation of the RYGB limbs (DGB), with shortening of the common channel and extending either the alimentary limb (AL) or biliopancreatic limb (BPL), can be performed as revisional surgery to induce additional weight loss. To date, there is no general consensus as to optimal surgical technique or limb lengths to be used in distalisation of RYGB in both literature as well as clinical practice.
Objective: The aim of this study is to investigate the effect of two distalisation techniques of a gastric bypass in revisional surgery with standardised limb lengths in total weight loss (TWL) and the need for treatment for protein calorie malnutrition (PCM). In this randomised controlled trial DGB with lengthening of the BPL (DGB type I) will be compared to DGB with extended AL (DGB type II) in order to conclude which surgical technique is the optimal therapeutic strategy as revision surgery following Roux-en-Y gastric bypass.
Study design: A multicentre randomised controlled trial.
Study population: Morbidly obese patients with insufficient weight loss or weight regain following primary RYGB, who are eligible for distalisation surgery.
Intervention: A total of 150 participants will be randomised over two treatment groups: group A will undergo DGB type I and group B will undergo DGB type II.
Main study endpoints: Primary endpoints: %TWL 1 year after treatment and need for treatment of PCM. Secondary endpoints: weight loss, co-morbidity remission, PCM grading (debilitating defecation patterns, temporary total parenteral nutrition treatment, revision, mortality), morbidity, nutritional deficiencies, quality of life and patient satisfaction.
