Purse string closure of perineal defects after abdominoperineal excision.

PURPOSE

The aim of this study was to describe a new technique of perineal closure following abdominoperineal excision (APE) using purse-string perineal skin closure (PSPC).

MATERIAL AND METHODS

Between January 2016 and May 2021, 15 consecutives patients who had an APE procedure were included in this retrospective single-center study. All indications of APE were considered, as well as all types of APE. We analyzed the patient characteristics and peri-operative features, including overall (Clavien 1 to 5) and severe (Clavien 3 and 4) postoperative morbidity, length of stay (LOS), and long-term results (median time to perineal wound closure and rate of perineal incisional hernia).

RESULTS

The patients included 11 men and four women, with a mean age of 64 ± 13 [33-80] years. The indication of APE was an epidermoid carcinoma of the anal canal (n = 5) or an adenocarcinoma of the rectum (n = 10). The mean operating time was 220 ± 88.64 [70-360] min. The overall morbidity rate was 60%, the severe morbidity rate 26%, and reoperation rate 26%. The median length of stay was 9 ± 6.5 days. After a mean follow-up of 23.5 ± 20.3 months, the median time to perineal wound closure was 96 ± 60 days, the persistent perineal sinus rate was 6% (n = 2), and one patient developed a perineal incisional hernia.

CONCLUSION

Purse-string closure of perineal wounds is a safe and effective technique for perineal wound closure after APE. The short LOS allowed an early return home.
