Research Article



In previous publications, we demonstrated the safety and short-term efficacy of laparoscopic sleeve gastrectomy (LSG) as a final step in the treatment of morbid obesity (MO). This study aimed to assess the mid-term efficacy of LSG.


We performed a retrospective review of a prospectively collected database. Between November 2004 and January 2007, 130 consecutive patients underwent LSG as a final procedure to MO. Data including patient demographics, operative time, length of hospital stay, complications, preoperative body mass index (BMI), complications, and weight loss at 3, 6, 12, 18, and 24 months were recorded and analyzed.


The mean age was 45.6 (range: 12–79) years while the mean BMI was 43.2 (range: 30.2–75.4) kg/m2. The mean operative time was 97 (range, 58–180) min and all operations were completed laparoscopically. The mean hospital stay was 3.2 (range, 1–19) days with zero mortality in this series.

One patient (0.7%) had leakage at the stapler line, while four patients (2.8%) developed trocar site infection. Three patients (2.1%) complained of symptoms of gastroesophageal reflux disease (GERD), three patients (2.1 %) developed symptomatic gallstones, and trocar site hernia was present in one (0.7%) patient. The mean weight loss was 21, 31.2, 37.4, 39.5, and 41.7 kg at 3, 6, 12, 18, and 24 months, respectively, while the mean BMI decreased to 36.9, 32.8, 29.5, 28, and 27.1 at 3, 6, 12 18, and 24 months, respectively. Percent of excess weight loss (%EWL) was 33.1, 50.8, 62.2, 64.4, and 67.9 at 3, 6, 12, 18, and 24 months, respectively.


LSG is a safe and effective surgical procedure for the morbidly obese up to 2 years. Excess body weight loss seems to be acceptable at 2 years postoperatively.
