Sleeve gastrectomy (SG) is the most frequently performed bariatric procedure globally. However, data regarding short- and long-term results remain insufficient. This study aimed to evaluate the short- and longterm effects of SG. We performed a thorough PubMed search for references that mentioned sleeve gastrectomy was carried out. In terms of weight loss and resolution of comorbid disorders, the immediate results have been encouraging. Although long-term results are still being obtained, a large number of individuals have experienced persistent weight loss. Eight short-term studies were extracted for the present review. Each study clarified that SG was utilized as a management technique for a high-risk patient population or as a component of a stepwise therapeutic procedure. The laparoscopic SG method was examined in all studies. The percentage of patients who were followed up for 30 days or longer after LSG was reported. Significant weight loss has been observed in studies that evaluated short-term results. An excess weight loss of 67.3% and a significant decrease in body mass index (BMI) were observed in a systematic evaluation of 5,218 patients. In long-term studies, SG was administered to 2713 patients, of whom 1626 completed the five-year follow-up period. Among all patients, 71.3% were women and 28.7% men. The mean BMI before surgery was 46.9 kg/m². The follow-up durations ranged from 5 to 11 years. The mean five-year follow-up rate was 66% (range 57-100%). At 5, 6, 7, 8 and 11 years, the mean percentage excess weight decreases were 58.4%, 59.5%, 56.6% and 62.5%, respectively. Five years after SG, resolution of type 2 diabetes resolved in 77.8% of patients, and arterial hypertension, dyslipidemia, obstructive sleep apnea, gastroesophageal reflux disease and degenerative joint diseases improved or resolved in 68.0%, 65.9%, 75.8%, 30.6% and 55.7% of patients, respectively. Laparoscopic SG is more technically straightforward and has fewer surgical complications than other more complex surgical techniques. Laparoscopic SG is an effective treatment option for bariatric surgery. It is relatively easy to perform, well tolerated by patients and effective for longterm excessive weight loss and resolution of comorbidities.
