A Decade of Sleeve Gastrectomy as a Single Bariatric/Metabolic Procedure: Analysis of Short and Long-term Outcome of 562 Patients

Obesity is a major healthcare problem reaching epidemic proportion and affecting people of all age (1). The only treatment that proven effective option for a significant substantial long-term weight loss and that cures or durably improves comorbidities is still bariatric surgery (2, 3). Because obesity is a chronic disease, it is widely accepted that to accurately assess the efficacy and durability of any type of bariatric surgery requires lifetime follow-up to assess for weight loss, co-morbidity changes, and nutritional deficiencies.

Despite initially performed as a first part of the staged procedures, the laparoscopic sleeve gastrectomy (LSG) has since introduced as a stand-alone bariatric operation associated with good, short and mid-term weight loss and satisfactory complication rates when conducted in experienced hands. Although simplicity and the overall efficacy of the procedure supported by meta-analysis and systematic review (4, 5), there are still limited long-term outcome data (6). Due to publication bias or multiple controversies regarding the technique of LSG, some of the available data may have underreported which has also been resulted in questioning the long-term weight loss efficacy of the procedure.

Although addressed by a recent consensus document,12 there are multiple controversies regarding the technique of LSG, and this may in part be what has led to the variable published results.

The study objective was to assess the long-term (≥ 5 years) as well as short (1 to ≤ 3 years) and mid-term (> 3 to < 5 years) results in regard to the BMI change, resolution of co-morbidities and complications in 562 consecutive morbidly obese patients undergoing LSG as a primary procedure.
