Abstract: Objective To investigate the influencing factors of postoperative gastroparesis syndrome (PSG) after laparoscopic right hemicolon cancer resection.Methods A total of 1070 patients with laparoscopic right hemicolon cancer resection (complete right hemicolon mesoresection) were selected from Wuhan General Hospital of Yangtze River Shipping and Wuhan Union Hospital Cancer Department from December 2012 to June 2022. According to whether the patients got postoperative gastroparesis, were divided into the postoperative gastroparesis syndrome (PSG) group or the normal control group. Univariate and multivariate Logistic regression analysis were used to analyze the risk factors of PGS after right hemicolon resection. Results There were 29 patients in the gastroparesis group and 1041 patients in the normal control group. Univariate analysis showed that age, perioperative blood glucose level, surgical resection range, and surgical approach were related to the occurrence of PGS (P<0.05). Multivariate Logistic analysis showed that age, high perioperative blood glucose level, caudal approach plus combined approach, and large surgical resection range were independent influencing factors of PGS (P<0.05).Conclusions Age, high perioperative blood glucose level, caudal approach plus combined approach, and large surgical resection range are influencing factors of PGS.
