Abstract
BACKGROUND: This study aims to evaluate the predictive value of pelvic anatomical and clinical-pathological parameters that influence the success of sphincter preservation procedure (SPP). METHODS: We studied 42 consecutive patients who underwent low anterior resection (LAR) with double stapling technique (DST) anastomosis or abdominoperineal resection (APR) for mid-low rectal cancer between June 2009 and April 2014. The surgical procedures were performed by the same surgeon and surgical team at the Department of Surgery of Wenzhou Central Hospital. Pelvic dimensions and angles were measured using three-dimensional reconstruction of spiral computed tomography (CT) images. A number of clinical-pathological parameters were also examined. Univariate and multivariate analyses were performed to determine the predictive significance of these variables that might affect a successful SPP for mid-low rectal cancer. RESULTS: Body mass index (BMI), distance of tumor from anal verge, and diameter of upper pubis to coccyx affected the success of SPP. It was the higher distance of tumor from anal verge, the higher BMI, and the larger diameter of upper pubis to coccyx contributed most to the success of SPP. CONCLUSIONS: Diameter of upper pubis to coccyx is the only one of the pelvic anatomical parameters that could affect the success of SPP for mid-low rectal cancer patients. Furthermore, within the normal BMI range, higher BMI seemed to be a favorable factor for the success of SPP.
