Successful wound management for infected perineum in recurrent rectal cancer by a two-step operation using muscle...

Perineal wound failure associated with infection is one of the intractable complications after abdominoperineal resection including pelvic exenteration. It is supposed that there is a strong possibility of this complication occurring in patients with infected perineal lesions after radiation therapy. We describe herein a case of a 56-year-old female who received pelvic exenteration for recurrent rectal cancer, the perineal wound of whom was successfully managed by a two-step operation using muscle flaps. The patient had a recurrent tumor in her pelvis after abdominoperineal resection for locally advanced rectal cancer. She had been treated with chemoradiotherapy for the recurrent tumor. The tumor was exposed to the perineum and was associated with bacterial infection. The tumor was curatively resected by total pelvic exenteration. The perineal wound infection was controlled by a lay-open method after reconstruction of the pelvic floor using a rectus abdominis muscle. The perineal wound was secondarily closed using gracilis mycocutaneous flaps 14 days after pelvic exenteration. She was discharged uneventfully 14 days after perineal closure. The strategy in the present report may be a useful option for perineal wound management in patients with a high risk of perineal wound failure due to infection after abdominoperineal resection.
