Introduction: A sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) are two of the most widely used bariatric procedures in Thailand but comparison of long-term outcomes are still limited. The aim of this study is to compare the degree of long-term weight loss after the laparoscopic Roux-en-Y gastric bypass (LRYGB) and sleeve gastrectomy (LSG).
Materials and Methods: A retrospective analysis was performed for all patients who underwent LSG or LRYGB between April 2005 and May 2018 at a single institution with at least 1 year to 5 years of follow up. Demographic data comprised age, sex, preoperative body weight, excess body weight, body mass index (BMI) and co-morbidities. The primary outcomes were percentage total weight loss and percentage excess weight loss. The secondary outcomes was postoperative complications.
Results: Of the total 368 patients, 163 underwent primary LSG and 205 patients underwent LRYGB between April 2005 and May 2018. Preoperative BMI in the LSG group was significantly more than the LRYGB group (53.7 ± 12.3 kg/m2 vs 48.4 ± 8.3 kg/m2, p <0.001). Co-morbidities between LSG and LRYGB were similar. Mean percentage of excess weight loss (%EWL) at 5 years was 36.7 ± 51.0% in the LSG group vs 62.3 ± 25.3% in the LRYGB group (p = 0.04). Mean percentage of total weight loss (%TWL) at 5 years was 19.2 ± 23.0% in the LSG group vs. 27.9 ± 11.8% in the LRYGB group (p = 0.252). At 5 years, no significant difference was found in the percentage of patients who had >50%EWL between groups. Overall complications were 4.3% in the LSG group vs. 11.7% in the LRYGB group (p = 0.011). The mortality rate was 0%.
Conclusion: Our center revealed LRYGB had better results than LSG in terms of percentage excess weight loss at 5 years. On the other hand, LSG had lower overall complications than LRYGB.
