To explore the surgical experience of Da Vinci robot system-assisted laparoscopic sleeve gastrectomy combined with partial fundus preservation combined with esophageal hiatal hernia repair.

A retrospective analysis of the clinical data of 11 patients who underwent the fourth-generation Da Vinci robot-assisted Kirschner new anti-reflux weight reduction surgery (laparoscopic sleeve gastrectomy combined with partial gastric fundus preservation plus esophageal hiatal herniorrhaphy) in the Department of minimally invasive, hernia and abdominal wall surgery in the people's Hospital of Xinjiang Uygur Autonomous region from April to September 2021.

All the 11 patients successfully completed the robot-assisted Kirschner new anti-reflux weight reduction surgery without conversion to laparotomy, including sleeve gastrectomy (LSG) combined with partial gastric fundus folding (Dor) plus esophageal hiatal hernia repair in 10 cases and combined with gastric fundus fold 360° (Nissen) plus esophageal hiatal hernia repair in 1 case. The average postoperative hospital stay was 5 days and the average operation time was 2.8 h. All 11 patients can be effectively followed up for 1-6 months without perioperative complications and recent complications.

Da Vinci robot-assisted Kirschner new anti-reflux weight reduction surgery (laparoscopic sleeve gastrectomy combined with partial gastric fundus preservation plus esophageal hiatal herniorrhaphy) is a safer and more effective minimally invasive surgery which hasthe advantages of finer anatomy, flexible operation and clearer field of vision during operation, which can achieve the dual purpose of anti-reflux and weight loss, and effectively prevent the occurrence and development of GERD.
