Introduction and Aim:

Laparoscopic sleeve gastrectomy (LSG) is considered one of the most popular bariatric surgeries of the present time. This review aimed to evaluate the progress and short-term outcomes of LSG over the last 5 years.


The systematic review of electronic databases revealed 27 relevant articles, which were carefully assessed. The data extracted from the studies were analyzed and compared with data reported by a previous review published in 2010.


A total of 5218 patients were included in this review with a mean age of 41.1. The average preoperative body mass index (43.8±8) significantly dropped at 12 months to 30.7±3.9. The average percentage of excess weight loss at 1 year was 67.3. The mean rates of remission of diabetes mellitus, hypertension, and dyslipidemia were 81.9%, 66.5%, and 64.1%, respectively. The mean complication rate across the studies was 8.7% and the average mortality rate was 0.3%. A significant drop in postoperative body mass index, higher percentage of excess weight loss, and significantly lower overall complication rate were observed in comparison with the previous systematic review.


LSG continues to achieve satisfactory weight loss and improvement of obesity-related comorbidities with acceptably low morbidity and mortality rates.
