Excess weight loss, Morbid obesity, Roux and Y Gastrik bypass, Sleeve gastrectomy


Background: Obesity an important health problem which has become a worldwide epidemic that effects both developed countries and developing countries. Bariatric surgery is the most efficient cure for morbid obesity. Authors retrospectively reviewed the results of different techniques in bariatric surgery to assess the efficiency of initial operations.

Methods: The medical files and operation notes and the one-year follow-up of patients were reviewed. The outcomes of sleeve gastrectomy (SG) and gastric roux-n-y bypass (RYGBP) operations were reviewed and their effects on excess weight loss were investigated.

Results: Overall, there were 97 patients included in the study, the majority of which were female (87/97, or 90%). The mean age of the SG group was 42.01±8.48 years versus 36±8.32 years in the RYGBP group, with p=0.007. Excess weight loss percentages were 51.7% and 57% for sleeve gastrectomy and RYGBP, respectively, p=0.491. Both operations are effective in reducing comorbidities.

Conclusions: In the RYGBP procedure there is more excess weight loss than the results of SG procedure but the difference is not statistically significant. In both procedures, the initial results on weight loss and reduction of comorbidities are comparable. Because SG is less traumatic and relatively easier to perform, it can be the preferred operation for morbid obesity.
