The standard surgical treatment for low rectal cancer is abdominoperineal resection (APR). Comparing to primary closure, immediate flap reconstruction has shown to have good outcomes. We aimed to assess the inferior rectus abdominis muscle flap complications after APR surgery, a new method of reconstruction.

This study was conducted from 2014 to 2016 in a single center in Firoozgar Hospital, Tehran, Iran. Eighteen patients who underwent pelvic floor closure with inferior part of abdominis rectus musculofascial flap were included enrolled. The sampling method used in this study was census. All patients had distal rectoanal malignancies. A checklist including age, gender, tumor location, complications after surgery, tumor type, length of hospital stay, length of operation, neoadjuvant chemotherapy and neoadjuvant radiotherapy history was filled for all patients.

Among 18 participants, 27.8% were female. The mean age of participants was 58.28 ± 17.86 yr (minimum of 19 and the maximum of 89 yr). The pathology of the tumor in all but one of the cases was adenocarcinoma (94.4%). The overall complication rate after surgery was 27.8%. In total, 80% received neoadjuvant chemoradiotherapy. In a one year follow-up, 16.8% of patients died.

Inferior part of rectus abdominis muscle flap was a reliable and comparable means of reconstruction after APR surgery with low rate of complications and mortality.

Abdominoperineal resection (APR) is the standard surgical treatment for low-lying anorectal malignancies. It seems that immediate flap reconstruction has fewer complications compared to primary closure. There are several options for local flap reconstruction of perineal wound closure, and each specific flap method has its own advantages and disadvantages.

In this case report, a new method of reconstruction is presented which contains only the inferior part of the rectus abdominis muscle in 2 patients, one with unilateral and the other with bilateral involvement and they both underwent APR. Both patients were referred to the colorectal surgery clinic for APR by an oncologist. Both patients had severe constipation and both reported pain on defecation and rectorrhagia. Patient 1 received a unilateral inferior part of rectus abdominis muscle flap and patient 2 received a bilateral flap.

Immediate flap reconstruction after APR has fewer complications than primary closure and the inferior part of rectus abdominis muscle flap seems to be a possible means of reconstruction after APR.
