Background:The introduction of individualized abdominoperineal excision (APE) may minimize operative trauma and reduce the rate of complications.The purpose of this study was to evaluate the safety and efficacy of individualized APE for low rectal cancer.Methods:Fifty-six patients who underwent individualized APE from June 2011 to June 2015 were evaluated retrospectively in Beijing Chaoyang Hospital,Capital Medical University.The main outcome measures were circumferential resection margin (CRM) involvement,intraoperative perforation,postoperative complications,and local recurrence.Statistical analysis was performed using SPSS version 16.0.Results:Fifty (89％) patients received preoperative chemoradiotherapy:51 (91％) patients were treated with the sacrococcyx preserved;27 (48％) patients with the levator ani muscle partially preserved bilaterally;20 (36％) patients with the levator ani muscle partially preserved unilaterally and the muscle on the opposite side totally preserved;7 (13％) patients with intact levator ani muscle and part of the ischioanal fat bilaterally dissected;and 2 (4％) patients with part of the ischioanal fat and intact lavator ani muscle dissected unilaterally and the muscle on the opposite side partially preserved.The most common complications included sexual dysfunction (12％),perineal wound complications (13％),urinary retention (7％),and chronic perineal pain (5％).A positive CRM was demonstrated in 3 (5％) patients,and intraoperative perforations occurred in 2 (4％) patients.On multiple logistic regression analysis,longer operative time (P =0.032) and more intraoperative blood loss (P =0.006) were significantly associated with perineal procedure-related complications.The local recurrence was 4％ at a median follow-up of 53 months (range:30-74 months).Conclusion:With preoperative chemoradiotherapy,individualized APE may be a relatively safe and feasible approach for low rectal cancer with acceptable oncological outcomes.
