Abstract: Objective To investigate the influenceof abdominal body shape parameters on perioperative complications and postoperative recovery in patients with laparoscopy-assisted distal D2 resection for gastric cancer（LADG）.
Methods 168 gastric cancer patients who underwent LADG were enrolled.The body mass index（BMI）and waist-to-hip ratio（WHR）were measured 4days before surgery，the abdominal body parameters[average umbilical abdominal wall thickness（NMT）and abdominal visceral fat thickness（VFT）]was measured by CT.The intraoperative and postoperative rehabilitation indicators and complications were counted.
Results Of the 168 patients，32 cases had perioperative complications，the complication rate was 19.05%.The Pearson correlation analysis showed that NMT was significantly positively correlated with postoperative anal exhaust time，eating time and hospital stay（P<0.05），VFT was negatively correlated with lymph node dissection（P<0.05），and VFT was positively correlated with operation time（P<0.05）.Multivariate logistic regression analysis showed that preoperative complications were independent risk factors for perioperative complications（P<0.05）.
Conclusion Abdominal body parameters have certain influence on the intraoperative and postoperative rehabilitation condition of LADG patients，but the effect on perioperative complications is not obvious.
