RESUMEN
Objective To study the abdominal perineal resection for rectal cancer and clinical application of pelvic floor recon-struction .Methods 30 cases of rectal cancer patients from 2008-2011 were randomly divided into experimental group and the con-trol group ,30 cases in each group .Experimental group patients by columnar abdominal perineal resection of rectal cancer treatment , postoperative pelvic floor defect for dermal matrix reconstruction .The control group patients for colorectal cancer resection by lapa-rotomy .Results Compared with the traditional open resection ,the operation time ,intraoperative blood loss ,postoperative patholog-ical column T3 N0 M0 positive rate ,incidence of complications and incision aspect of cylindrical abdominal perineal resection were ob-vious advantages ,the difference was statistically significant (P< 0 .05) .Conclusion Compared with Miles surgery ,cylindrical ab-dominal perineal resection for rectal cancer can reduce the incidence of postoperative incisal edge positive rate and bowel perfora -tion .Human decellularized dermal matrix basin redevelopment can significantly reduce the surgical risk and difficulty of surgical op-erations .
