The purpose of this study was to determine whether the type of operation [sphincter-saving resection (SSR) or abdominoperineal resection (APR)] for primary adenocarcinoma of the rectum at or below the peritoneal reflection affects survival and recurrence after curative surgery.


This retrospective study included 184 patients who underwent curative surgery achieved by the following two types of operation between 1989 and 1998: (1) SSR ( n = 116 patients) including a low anterior resection with either double-stapling technique ( n = 86) or transanal coloanal anastomosis ( n = 30); (2) APR ( n = 91). The outcome factors evaluated were survival and tumor recurrence. Both univariate and corrected (multivariate Cox's and logistic regression) analyses were used to evaluate the data. The median follow-up was 47.4 months for patients alive at study conclusion.


Disease-free and disease-specific survivals, and the frequency and location of recurrence after surgery did not differ between the two types of operations. Multivariate analyses showed that the type of operation was not a significant independent variable in predicting disease-free survival or in the development of both local and distant recurrences after surgery. In addition, tumor-related factors (stage or histologic grade) were significant predictors of the outcome after surgery.


The type of operation (SSR or APR) did not affect the survival or recurrence after a curative resection for adenocarcinoma of the rectum at or below the peritoneal reflection.
