Objectives: Estimated weight loose (EWL) is an important parameter in bariatric surgery indicating the postoperative success in weight loss. We aimed to compare the EWL in sleeve gastrectomy and roux-en-y gastric by-pass.

Materials and Methods: During  a one-year period (2013) data of patients who underwent bariatric surgery in our clinic were recorded prospectively including demographical data, operation type, preoperative Body Mass Index (BMI) and postoperative 1st-3rd-6th and 12th month BMI. The patients were analyzed in two groups; GroupS(n=30): patients who underwent sleeve gastrectomy and GroupR(n=30): patients who underwent Roux-En-Y Gastric  By-Pass.

Results: There was no statistically significant difference regarding the patients’ demographics and perioperative complication rates. Body Mass Index(BMI) was 51,3+/-8,5 in GroupS and 56,1+/-7,3 (p=0.024).

Conclusion: Albeit Roux-En-Y Gastric By-Pass is a more invasive procedure compared to sleeve gastrectomy and has its own handicaps related to the operational procedure, this study indicated that Roux-En-Y Gastric By-Pass is more successfull in EWL compared to sleeve gastrectomy. However, sleeve gastrectomy is a more simple procedure compared to Roux-En-Y Gastric By-Pass and with mean 80,9% EWL sleeve gastrectomy can be choosen alternatively to Roux-En-Y Gastric By-Pass, which has a 89,2% EWL.
