Abstract:
Objective:To explore the anti-reflux effect of transverse fan-shaped groin formed (TFGF) when the residual stomach is large (the small curvature ≥10 cm).Methods:Twenty-four patients with residual curvature ≥10 cm after PG were treated with TFGF continuously from Nov 2020 to Dec 2023 in this study. The cohort included 20 patients with Siewert type Ⅱ adenocarcinoma of the esophagogastric junction and 4 patients with achalasia of cardia. Reflux disease questionnaire score gastroesophageal reflux disease questionnaire score and gastroscopy Los Angeles score were used to evaluate the anti-reflux effect and postoperative nutritional parameters (hemoglobin, protein and body weight).Results:The reconstructive operation time of adenocarcinoma of the esophago-gastric junction and achalasia of cardia was (20.0±5.1) min and (18.3±4.7) min, respectively. reflux disease questionnaire, gastro-esophageal reflux disease questionnaire and gastroscopy indicated GERD in 3 patients and 8% in 2 patients at 24 months. At follow-up, one patient transitioned from grade B to grade C based on the Los Angeles score at 12 months; 24 months after surgery, one patient's gastroesophageal reflux symptoms resolved and the Los Angeles rating was downgraded from B to A. Nutritional indicators (hemoglobin, protein and body weight levels) all showed a downward trend at 6 months and an upward trend at 24 months.Conclusion:TFGF has the advantages of simple operation, and effective prevention of postoperative gastroesophageal reflux for patients with lesser residual curvature ≥10 cm after PG.
