Abstract:
Objective:To explore whether the protective ileostomy can reduce the incidence of anastomotic leakage after neoadjuvant treatment of rectal cancer and the relationship between protective ileostomy and anastomotic leakage.Methods:From May 2011 to August 2020, a total of 108 patients who underwent rectal cancer neoadjuvant radiotherapy and chemotherapy and then received anterior resection in Beijing Friendship Hospital, Capital Medical University were selected. Sixty-three cases were treated with protective ileostomy (Treatment group), while 45 cases were not (Control group). The chi-square test was used to compare the incidence of anastomotic leakage between the two groups. At the same time, Logistic regression was used to analyze the related factors of anastomotic leakage, and the rate of permanent stoma was calculated. SPSS19.0 software was used for statistical analysis.Results:The total incidence of postoperative anastomotic leakage in the Treatment group and Control group was 9.52% (6/63) and 6.66% (3/45) ( P=0.59). Among them, 2 cases of anastomotic leakage occurred in the Treatmentgroup, no A-grade anastomotic leakage occurred in the Control group, and there was no significant difference between the two groups (33.33% vs. 0, P=0.77). There were 4 cases of grade B anastomotic leakage occurred in the Treatment group, 2 cases in the Control group, there was no significant difference between the two groups (66.67% vs. 66.67%, P=0.45). There was no grade C anastomotic leakage in the Treatment group, and one case of grade C anastomotic leakage occurred in the Control group, there was no significant difference between the two groups (0 to 33.33%, P=0.70). Logistic regression analysis showed that whether protective stoma was implemented or not was not statistically related to the occurrence of anastomotic leakage ( P=0.26). The distance between the tumor and the anal margin ( P=0.01) affected the occurrence of anastomotic leakage. The permanent stoma rate in the Treatment group was 9/63 (16.67%). Conclusion:Protective ileostomy has no significant advantage in reducing the incidence of anastomotic leakage in patients with rectal cancer neoadjuvant radiotherapy and chemotherapy, and may lead to permanent stoma.
