Management of the perineal wound with constant irrigation and suction after abdominoperineal excision for cancer of the rectum. A new suction/irrigation drain.

The technique of primary closure of the perineal wound combined with continuous irrigation and suction of the operative site has been used in 21 patients who underwent abdominoperineal excision for cancer of the rectum or anal canal. Primary healing occurred in 19 patients within 18 days, and all patients healed within 2 months. These results are in marked contrast to those in 38 patients treated with constant suction alone, of whom only 17 healed primarily.
