BackgroundLaparoscopic sleeve gastrectomy (LSG) has emerged as an alternative restrictive bariatric procedure to the most popular laparoscopic adjustable gastric banding (LAGB). We analyze and compare the clinical and weight loss outcomes of LSG versus LAGB for the treatment of severe obesity in high-risk patients.MethodsForty severely obese veterans (20/group) received either LSG or LAGB and were followed prospectively for 2 years. Outcome measures included operating room (OR) time, estimated blood loss (EBL), length of hospital stay (LOS), morbidity, mortality, reoperations, readmission rates, and weight loss over time.ResultsThe cohort primarily comprised high-risk and older male veterans. Patient's baseline demographics were similar between groups. LSG was associated with prolonged OR time (116±31 vs. 94±28min), higher EBL (34±28 vs. 17±19mL), and LOS (2±.9 vs. 1±.4days) when compared with LAGB. Minor morbidity and readmissions were similar between groups, while no major morbidity, reoperations, or mortality occurred. Total weight and BMI decreased significantly after surgery in both groups (LSG: 302±52 to 237lbs and 45±5 to 36±5kg/m(2) vs. LAGB: 280±36 to 231±29lbs and 43±5 to 36±5kg/m(2), respectively). Total weight loss was superior in the LSG vs. LAGB group at 2 years (TWL=65±24 vs. 49±28 lbs (P=.03); %EWL=51±20 vs. 46±23%; %EBMI loss=48±22 vs. 45±23%, and %BWL=21±8 vs. 17±9%, respectively).ConclusionIn severely obese and high-risk patients, laparoscopic sleeve gastrectomy provides superior total weight loss at 2 years.
