Long-Term Outcomes of Laparoscopic Roux-en-Y Gastric Bypass in US Veterans
Background The objective of this study is to evaluate the long-term outcomes following  laparoscopic Roux-en-Y gastric bypass ( LREYGB ) in veteran patients . The VA bariatric population differs from its counterpart in the private sector by the predominance of a male population , a higher percentage of patients from a lower socioeconomic background , a higher mean age , and a higher rate of obesity-related comorbidities . Methods A retrospective review with prospect ively collected data was used to analyze postoperative changes of comorbidities and percent of excess weight loss ( % EWL ) in consecutive patients who underwent LREYGB between August 2003 and September 2006 . Results Among 70 patients , 73 % were men with a mean age of 52 years ( 29–66 years ) . Average preoperative weight and body mass index were 310 lbs ( 224–397 lbs ) and 46 kg/m2 ( 36–60 kg/m2 ) , respectively . The incidence of major and minor complications was 1.4 % and 15.7 % , respectively . There were no mortalities . Follow-up ( f/u ) was possible in all patients . At a mean f/u rate of 39 months , % EWL was 56 % . At 1 , 3 , and 5 years , % EWL was 61 % , 53 % , and 59 % , respectively . Thirty-five patients ( 50 % ) had type 2 diabetes mellitus ( T2DM ) . Glycosylated hemoglobin concentrations returned to normal levels in 91 % of patients and improved in an additional 6 % of T2DM cases . Only 7 % of patients are still maintained on antidiabetic medications . In patients with more than 1 year f/u , most other comorbidities were improved or resolved . Conclusions Long-term f/u of LREYGB in veteran patients demonstrated significant and durable weight loss ( 56 % EWL ) with marked improvements in comorbidities especially T2DM
