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 Patients lost to follow-up did not attend scheduled follow-up visits or they have withdrawn their consent.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.
