Abstract:
Objective:Clavien-Dindo grading system was used to explore the occurrence and related risk factors of early severe complications after radical resection of gastric cancer, and the effect of severe complications on long-term prognosis was analyzed.Methods:The clinical data of 525 patients who underwent radical resection of gastric cancer, including 387 male and 138 female with average age(62.5±10.7)years old (range from 16 to 89 years), were analyzed retrospectively in Department of Surgical Oncology of Anqing Municipal Hospital from October 2010 to July 2015. The occurrence of postoperative severe complications was analyzed according the Clavien-Dindo grade system.The relationship between 18 variables and severe complications was analyzed by univariate and multivariate analysis in order to explore the risk factors of severe postoperative complications, and the relationship between severe complications and long-term prognosis was analyzed by COX survival model. The software of SPSS 17.0 was used to conduct statistic analysis.Results:Five hundred and twenty-five patients with radical gastrectomy, 114 cases had early postoperative complications, including 20 cases of severe complications, 4 cases were performed second surgery under general anesthesia. The results of univariate analysis showed gender( χ2=4.86, P=0.027), the amount of bleeding( χ2=11.11, P=0.001), opertive time( χ2=4.77, P=0.029), the mode of operation( χ2=9.20, P=0.002) and pTNM stage( χ2=4.86, P=0.027) had significant statistical difference. Multivariate analysis showed that the amount of bleeding ( OR=13.05, P=0.013) and the mode of operation ( OR=7.97, P=0.047) were independent risk factors for early and severe complications after radical resection of gastric cancer. The 5-year survival rates of severe complication and non-severe complication were 35.0% and 61.8% respectively, and the difference was statistically significant ( P=0.004). Severe postoperative complications ( HR=1.595, P=0.107) were not independent risk factors affecting the 5-year survival rate. Conclusions:Early severe complications after radical resection of gastric cancer are closely related to intraoperative blood loss and total gastrectomy. Although the 5-year survival rate in severe complication group is significantly lower than that in non-severe complication group, severe complication is not an independent risk factor for long-term survival.
