Abstract:
Bariatric and metabolic surgery has become a primary treatment for decompensated obesity, with the number of procedures rapidly increasing in China in recent years. Various improved and novel surgical techniques have emerged. Given the characteristics of the Chinese obese population lower body mass index compared to Western populations and frequent pancreatic islet dysfunction laparoscopic Roux-en-Y gastric bypass remains one of the mainstream procedures in China. Although the Procedural Guideline for Laparoscopic Roux-en-Y Gastric Bypass (2019 Edition) has provided standardized surgical steps, mastering and routinely implementing the procedure in clinical practice continues to pose significant challenges. Compared to laparoscopic sleeve gastrectomy, laparoscopic Roux-en-Y gastric bypass is more technically demanding and requires a longer learning curve. To avoid suboptimal weight loss or severe postoperative complications resulting from non-standardized techniques, this article summarizes the authors' clinical experience, emphasizing key technical steps: creation of the gastric pouch, standardization of gastrojejunal and jejunojejunal anastomoses, hiatal closure, and full serosalization. These insights aim to improve procedural safety and therapeutic efficacy by offering a set of practical process optimization strategies.
