Methods: From July 2011 to December 2014 there is 70 patients (45 woman; 64 percent) with an average age of 37.7 years (range; 17-62 years), mean body weight was 126.5 kg (range; 83-250 kg), mean BMI was 45.7 kg/m2 (range; 33-77 kg/m2) who underwent laparoscopic sleeve gastrectomy for treatment morbid obesity. Postoperative time, 1st day postoperative pain, postoperative complication and postoperative follow up data for the body weight change, percent EWL, BMI and improvement of comorbidity at the 6th, 9th,12th, 18th, and 24th months were recorded. Results: The mean operative time was 75 minutes. The mean operative blood loss was 20 ml. The mean 1st day postoperative pain score was 4. No conversion to laparotomy had to be performed.
