Extensive perineal and pelvic defects reconstructed simultaneously using bilateral pedicled gracilis and rectus abdominis muscle flaps after en-bloc excision of locally invasive perineal mucinous adenocarcinoma 1.

We report a case of successful simultaneous reconstruction of pelvic and perineal defects using bilateral pedicled gracilis and inferiorly based rectus abdominis muscle flaps after en-bloc excision of the tumour and abdominoperineal resection of locally advanced invasive perineal mucinous adenocarcinoma originating from a chronic anal fistula.
