Background: Perineal wound complications(PWCs)are common after abdominoperineal resection(APR). We examined the incidence of PWCs after APR for anorectal lesions and their risk factors.
Methods: Patients who underwent APR for anorectal lesions at our hospital from January 2011 to December 2021 were included. Complications of Clavien-Dindo Grade Ⅱ or higher were considered as PWCs.
Results: Eighty-one patients were included; PWCs were observed in 24 patients (29.6%), and associated with a history of Crohn's disease(p=0.018), longer operation time(p=0.040), higher blood loss (p=0.011), extensive perineal resection(p=0.003), and closure with a skin flap(p=0.003). Forty-one patients underwent APR for initial rectal cancer without extended perineal resection, and PWCs were observed in 9 patients(22.0%). Prognostic nutritional index(PNI)<45(p=0.049), smoking(p=0.034), and alcohol consumption(p=0.021)were associated with PWCs.
Conclusion: We examined the incidence of PWCs after APR for anorectal lesions and their risk factors. Appropriate intervention in nutrition, smoking, and alcohol consumption may prevent PWCs.
