Factors Associated With Oncologic Outcomes After Abdominoperineal Resection Compared With Restorative Resection for Low Rectal Cancer

Abstract

Technical factors alone are unlikely to be responsible for the worse outcomes after abdominoperineal resection in comparison with restorative resection. A combination of patient- and tumor-related factors that may have indicated the choice of the procedure also probably contribute to the worse outcomes. Because patients undergoing abdominoperineal resection represent a high risk for poor outcomes, management strategies need to consider all these factors during treatment.
