Preliminary outcomes 1 year after laparoscopic sleeve gastrectomy based on bariatric analysis and reporting outcome system (BAROS)

Abstract

Background: The aim of this study was to assess outcomes of laparoscopic sleeve gastrectomy (LSG) as a stand-alone bariatric operation according to the Bariatric Analysis and Reporting Outcome System (BAROS). Methods: Out of 112 patients included and operated on initially, 84 patients (F/M, 63:21) were followed up for 14-56 months (mean 22±6.75). Patients lost to follow-up did not attend scheduled follow-up visits or they have withdrawn their consent. Mean age was 39 years (range 17-67; SD±12.09) with mean initial BMI 44.62 kg/m 2 (range 29.39-82.8; SD±8.17). Statistical significance was established at the p<0.05 level. Results: Mean operative time was 61 min (30-140 min) with mean hospital stay of 1.37 days (0-4; SD±0.77). Excellent global BAROS outcome was achieved in 13% of patients, very good in 30%, good in 34.5%, fair 9.5% and failure in 13% patients 12 months after surgery. Females achieved significantly better outcomes than males with the mean 46.5% of excess weight loss (EWL) versus 35.3% of EWL at 12 months (p=0.02). The mean percentage of excess weight loss (%EWL) was 43.6% at 12 months and 46.6% at 24 months. Major surgical complication rate was 7.1%; minor surgical complication rate 8.3%. There was one conversion (1.2%) due to the massive bleeding. Comorbidities improved or resolved in numerous patients: arterial hypertension in 62%, diabetes mellitus in 68.3%, respectively. Conclusions: Presented LSG series shows that the LSG as a stand-alone procedure provides acceptable %EWL and good global BAROS outcomes. It significantly improves comorbidities as well. © 2011 The Author(s).
