Purpose
Intensified treatment for distal rectal cancer has improved oncological outcome, but at the expense of more perineal wound complications in patients undergoing an abdominoperineal resection (APR). The aim of this study was to analyse perineal wound healing after APR with primary perineal wound closure over time.
Method
All patients undergoing APR for primary rectal cancer with primary wound closure between 2000 and 2013 were included and analysed in three consecutive time periods. Both early (<30 days postoperatively) and late perineal wound complications were determined. Independent risk factors of early perineal wound complications were identified using multivariable analysis.
Results
A total of 136 patients were identified, of whom 129 patients underwent primary perineal wound closure. The use of neo-adjuvant (chemo)radiotherapy increased from 72 to 91 %, and the use of an extralevator approach increased from 9 to 19 %. The rate of early perineal wound complications increased from 18 to 31 % and was independently associated with an extralevator approach [odds ratio (OR) 3.17; 95 % confidence interval (CI) 1.16–8.66] and intra-operative perforation (OR 3.35; 95 % CI 1.06–10.57). Perineal wound complications had no impact on local recurrence or 3-year overall survival rate. During a median follow-up of 28 months [interquartile range (IQR) 14–56], a persistent presacral sinus was diagnosed in 10 %, and a perineal hernia occurred in 8 % of the patients.
Conclusion
The increased use of an extralevator APR for rectal cancer significantly increased the risk of perineal wound complications over time. Intra-operative perforation was also independently associated with impaired perineal wound healing.
