Short‐Term Outcomes and Quality of Life After Robotic Versus Laparoscopic Double‐Flap Technique for Proximal Gastrectomy: A Retrospective Cohort Study

Background Robotic systems may facilitate the double‐flap technique (DFT) after proximal gastrectomy (PG), yet the superiority of robotic DFT following PG (RPG‐DFT) over laparoscopic PG with DFT (LPG‐DFT) remains unclear. Methods Seventy‐three gastric cancer patients (28 RPG‐DFT, 45 LPG‐DFT) were compared for baseline characteristics, perioperative outcomes, and 3‐month postoperative data. Gastroesophageal Reflux Disease‐Health Related Quality of Life (GERD‐HRQL) and weight loss are postoperative primary endpoints. Results RPG‐DFT had significantly longer operative time (308.3 vs. 204.5 min, p < 0.0001) but shorter postoperative hospital stay (6.21 vs. 8.13 days, p < 0.0001). By postoperative day 3, RPG‐DFT showed faster decline in inflammatory markers (NLR, PLR, MLR, SII). No significant differences were observed in reflux symptoms or anastomotic stenosis rates. Conclusion Compared to LPG‐DFT, RPG‐DFT facilitates accelerated patient recovery, as evidenced by a rapid decline in inflammatory markers and reduced length of hospital stay.
