Purpose
Perineal wound infection (PWI) rates are high after abdominoperineal resection (APR) and total pelvic exenteration (TPE). This study identified risk factors for PWI after surgery for anorectal tumors and examined the relationship between the surgical excision volume with the PWI degree.
Methods
A retrospective review involving 135 patients who underwent surgical excision of anorectal tumors was performed. Superficial PWI included cellulitis and superficial dehiscence; deep PWI included major dehiscence, perineal abscess, and presacral abscess. The adjacent organ resection type was classified according to the dead space size formed by surgical excision.
Results
Of the 135 patients, 119 underwent APR, and 16 underwent TPE. PWI occurred in 75 patients (superficial PWI, 44; deep PWI, 31). Adjacent organ resection was an independent risk factor for PWI. The cases with adjacent organ resection were classified into small-defect APR, large-defect APR, and TPE. Large-defect APR and TPE cases had significantly higher rates of deep PWI than APR cases without adjacent organ resection.
Conclusions
Adjacent organ resection involving the removal of one or more organs and that involving wide-range muscle resection are strong risk factors for deep PWI.
