Abstract
Purpose
This study aimed at analyzing retrospectively the risk factors for anastomotic leakage for lower rectal cancer treated with preoperative radiotherapy.
Methods
The subjects were 108 patients with T3 lower rectal cancer, who underwent curative resection following preoperative radiotherapy. All patients had a diverting stoma made. Univariate and multivariate analyses were conducted for the independent clinical variables.
Results
Anastomotic leakage developed in 19 (17.6 %) patients. Univariate analysis of the risk factors for anastomotic leakage revealed that arterial ligation with a high tie (p = 0.001), undifferentiated tumor type (p = 0.002), a shorter distance from the anal verge (p = 0.086), and a longer hospital stay (p = 0.0002) were significant predictors of leakage. Multivariate analysis revealed that a high tie [hazard ratio 12.22 (95 % confidence interval 2.83–87.94); p = 0.0003], undifferentiated tumor type [91.15 (5.98–3128.03); p = 0.0008], and a long hospital stay [13.03 (2.86–104.93); p = 0.0004] were independently associated with anastomotic leakage.
Conclusion
Our data suggest that preoperative radiotherapy and a high tie for lower rectal cancer are independent risk factors for anastomotic leakage.
