Outcomes of laparoscopic sleeve gastrectomy at a bariatric unit in South Africa

- First study of laparoscopic sleeve gastrectomy performed in South Africa.
- Laparoscopic sleeve gastrectomy produces an adequate percentage excess BMI loss at 6 months.
- A significant improvement in the quality of life was observed.
- Results of this research are comparable to other studies of LSGs.
- Low complication rate supports the use of the procedure.

BackgroundLaparoscopic sleeve gastrectomy (LSG) has gained popularity over the years as a standalone procedure. In 2014, it was the most rapidly growing bariatric procedure. The aim of this study was to describe the outcomes of LSG at a single bariatric unit in Johannesburg, South Africa, using the Bariatric Analysis and Reporting Outcome System (BAROS) standardised scoring.MethodsA retrospective record review and analysis was carried out using data collected from patients who had LSGs. The information obtained included patient demographics, comorbidities, preoperative weight and height, operative technique, time and complications, postoperative gastrografin swallow results, hospital stay, and weight at 6 months postoperatively. The percentage of excess body mass index (BMI) loss (%EBMIL) was calculated at 6 months, and included in the BAROS questionnaire completed by the patients at the 6-month follow-up visit. Statistical significance was set at p < 0.05.ResultsA total of 103 patients were included in the study; of these, 85.4% were female and 14.6% were male. The mean preoperative BMI was 42.1 kg/m2; additionally, 77.7% of the patients in the study had comorbidities prior to the procedure. The mean operative time was 104.3 min, with a mean hospital stay of 2.5 days. No mortalities occurred, and a complication rate of 7.7% was encountered. At the 6-month follow-up, the mean %EBMIL was 65%. When followed up at 6 months, all 103 patients demonstrated no failures according to the BAROS assessment. It was found that 96.1% had good, very good or excellent outcomes. In total, 9.7% of the patients had an excellent outcome.ConclusionsLSG was shown to produce an adequate %EBMIL loss at 6 months, resulting in a significant improvement in the quality of life (QoL), coupled with good BAROS outcomes. The results of this research are comparable to other studies of LSGs, and the low complication rate supports the use of the procedure and accounts for no observed mortality.
