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.
