About this study

Obesity remains a major global health challenge, with rising prevalence and significant metabolic, cardiovascular, and gastrointestinal comorbidities. Laparoscopic sleeve gastrectomy (LSG) has emerged as the most widely performed bariatric procedure due to its technical simplicity and satisfactory short- to mid-term results. However, a proportion of patients experience suboptimal weight loss, recurrent weight gain, or both. In this study, patients with recurrent weight gain of maximum weight loss or suboptimal weight loss or both following sleeve gastrectomy were included. Suboptimal weight loss is defined as total weight loss (TWL) of less than 20% of the preoperative weight and/or excess weight loss (EWL) of less than 50%, measured at least 12-18 months after the primary sleeve gastrectomy. Recurrent weight gain after sleeve gastrectomy is defined as an increase of ≥20% of the maximum weight loss (from nadir weight) or an increase in BMI of \>5, measured at least 24 months after the primary procedure.
