Abstract
Purpose: Long-term studies on the outcomes of bariatric surgery are still limited in the Middle East. The aim of this study is to compare the outcomes of laparoscopic Roux-en-Y gastric bypass (LRYGB) and sleeve gastrectomy (LSG) up to 5 years of follow-up. Materials and Methods: A retrospective analysis of patients who underwent LRYGB and LSG was performed. The primary outcome was weight loss. Postoperative complications, operative time, and hospital length of stay were secondary outcomes. Results: Four hundred patients underwent primary LSG and 175 patients underwent LRYGB between 2008 and 2013. Follow-up rates at 5 years were around 60%. Percent total weight loss was similar after 3, 4, and 5 years in both groups, averaging around 28%. Mean percentage of excess weight loss (%EWL) at 5 years was 72.0 ± 31.0% in the LSG group vs. 63.0 ± 21.0% in the LRYGB group (p = 0.03). Patients undergoing LRYGB had a significantly longer operative time as well as a longer hospital stay. No significant difference was found in the rates of short- and long-term complications between the two groups. However, patients undergoing LRYGB were more likely to develop small intestinal obstruction and iron-deficiency anemia. Conclusions: Both LSG and LRYGB result in satisfactory weight loss within 5 years. Patients’ comorbidities and potential risks must be included in the choice of the appropriate bariatric procedure. LSG appears to give durable weight loss with less risk of major long-term complications. © 2017, Springer Science+Business Media, LLC.
