Article Abstract

Abdominoperineal resection (APR) and sphincter-preserving resection (SPR) are the two primary surgical options for rectal cancer. Retrospectively we collected rectal cancer patients for SPR and APR observation between 2005 and 2007. The patient-related, tumor-related, and surgery-related variables of the SPR and APR groups were analyzed by using logistic regression techniques. The mean distance from the anal verge (DAV) of cancer is significantly higher in SPR than that in APR (P<0.001). In cancers with DAV<40 mm (SPR, 40 versus APR, 110), multivariate analysis shows that surgeon procedure volume (odds ratio [OR]=0.244; 95% confidence interval [CI]: 0.077-0.772; P=0.016) and neoadjuvant radiotherapy (OR=0.031; 95% CI: 0.002-0.396; P=0.008) are factors influencing SPR. In cancers with DAV ranging from 40 mm to 59 mm (SPR 190 versus APR 50), analysis shows that patient age (OR=2.139; 95% CI: 1.124-4.069; P=0.021), diabetes (OR=2.657; 95% CI: 0.872-8.095; P=0.086), and colorectal surgeon (OR=0.122, 95% CI: 0.020-0.758; P=0.024), are influencing factors for SPR. The local recurrence and disease-free survival reveal no significant difference. A significant difference exists in DAV, surgeon specialization, procedure volume, age, diabetes, and neoadjuvant radiotherapy between SPR and APR.
