Primary suture of the perineal wound using constant suction and irrigation, following rectal excision for inflammatory bowel disease.

Thirty-four consecutive patients with inflammatory bowel disease underwent proctectomy with primary closure of the perineal wound. Throughout this period neither preoperative perineal sepsis nor intraoperative soiling was a contraindication to primary closure. An overall primary healing rate of 82% was obtained. It appears that the commonest cause of perineal wound breakdown is the inability of the suction catheter to drain all the serous fluid from the perineal space, resulting in discharge from the suture line and wound breakdown.
