Five-year outcomes after laparoscopic gastric bypass and laparoscopic duodenal switch in patients with body mass index of 50 to 60: a randomized clinical trial.
IMPORTANCE There is no consensus as to which bariatric procedure is preferred to reduce weight and improve health in patients with a body mass index higher than 50 . OBJECTIVE To compare 5-year outcomes after Roux-en-Y gastric bypass ( gastric bypass ) and biliopancreatic diversion with duodenal switch ( duodenal switch ) . DESIGN , SETTING , AND PARTICIPANTS R and omized clinical open-label trial at Oslo University Hospital , Oslo , Norway , and Sahlgrenska University Hospital , Gothenburg , Sweden . Participants were recruited between March 17 , 2006 , and August 20 , 2007 , and included 60 patients aged 20 to 50 years with a body mass index of 50 to 60 . The current study provides the 5-year follow-up analyses by intent to treat , excluding one participant accepted for inclusion who declined being operated on prior to knowing to what group he was r and omized . INTERVENTIONS Laparoscopic gastric bypass and laparoscopic duodenal switch . MAIN OUTCOMES AND MEASURES Body mass index and secondary outcomes including anthropometric measures , cardiometabolic risk factors , pulmonary function , vitamin status , gastrointestinal symptoms , health-related quality of life , and adverse events . RESULTS Sixty patients were r and omly assigned and operated on with gastric bypass ( n = 31 ) and duodenal switch ( n = 29 ) . Fifty-five patients ( 92 % ) completed the study . Five years after surgery , the mean reductions in body mass index were 13.6 ( 95 % CI , 11.0 - 16.1 ) and 22.1 ( 95 % CI , 19.5 - 24.7 ) after gastric bypass and duodenal switch , respectively . The mean between-group difference was 8.5 ( 95 % CI , 4.9 - 12.2 ; P < .001 ) . Remission rates of type 2 diabetes mellitus and metabolic syndrome and changes in blood pressure and lung function were similar between groups . Reductions in total cholesterol , low-density lipoprotein cholesterol , triglycerides , and fasting glucose were significantly greater after duodenal switch compared with gastric bypass . Serum concentrations of vitamin A and 25-hydroxyvitamin D were significantly reduced after duodenal switch compared with gastric bypass . Duodenal switch was associated with more gastrointestinal adverse effects . Health-related quality of life was similar between groups . Patients with  duodenal switch underwent more surgical procedures related to the initial procedure ( 13 [ 44.8 % ] vs 3 [ 9.7 % ] patients ; P = .002 ) and had significantly more hospital admissions compared with patients with gastric bypass . CONCLUSIONS AND RELEVANCE In patients with a body mass index of 50 to 60 , duodenal switch result ed in greater weight loss and greater improvements in low-density lipoprotein cholesterol , triglyceride , and glucose levels 5 years after surgery compared with gastric bypass while improvements in health-related quality of life were similar . However , duodenal switch was associated with more surgical , nutritional , and gastrointestinal adverse effects . TRIAL REGISTRATION clinical trials.gov Identifier : NCT00327912
