Single-incision bariatric surgery: advantages and challenges

Single-incision bariatric surgery, as a significant advancement in minimally invasive surgery, achieves weight loss goals through a single small incision, offering advantages such as minimal trauma, concealed scarring, and rapid postoperative recovery. The single-incision laparoscopic sleeve gastrectomy (SILSG) currently represents the most widely performed single-incision bariatric procedure globally, demonstrating weight loss efficacy and complication rates comparable to traditional multi-incision laparoscopy alongside significantly higher patient satisfaction. However, the clinical adoption of single-incision bariatric surgery still faces technical challenges with relative scarcity in robust clinical research evidence and underdeveloped standardized surgical protocols and training systems. To further establish a specialized training system and expert consensus for single-incision bariatric surgery that aligns with China's national conditions is of great significance for promoting the standardized implementation of SILSG-represented procedures.
