Benefits of perineal colostomy on perineal morbidity after abdominoperineal resection.
OBJECTIVE
Abdominoperineal resection has a high rate of postoperative morbidity of the perineal wound. This study aimed to determine the effects of perineal colostomy on perineal morbidity after abdominoperineal resection.


METHODS
All patients who underwent an abdominoperineal resection for rectal adenocarcinoma between 1993 and 2007 were studied. Two groups were identified and compared who had undergone either an iliac colostomy or a perineal colostomy.


RESULTS
The analysis included 110 patients (iliac colostomy group, n = 41; perineal colostomy group, n = 69). There were fewer instances of pelviperineal morbidity (P = .008) and fewer instances of wound dehiscence (P = .02) in the perineal colostomy group, which resulted in a shorter time to healing (35.3 vs 45.1 d, respectively; P = .04). There was no specific postoperative morbidity in any patient and no difference between the 2 groups regarding long-term perineal morbidity. The benefits from perineal colostomy were statistically significant in patients who received radiation therapy in terms of pelviperineal morbidity (P = .01) and healing time (50.8 vs 35.9 days, respectively; P = .02), whereas no difference was found in patients who had not received radiation therapy.


CONCLUSIONS
Perineal colostomy is a safe and functionally acceptable procedure for perineal reconstruction after abdominoperineal resection for rectal adenocarcinoma. In the present study, there was no additional morbidity related to perineal colostomy, and this procedure was associated with a decrease in perineal morbidity and healing time compared with primary perineal closure, in particular, after radiotherapy treatment.
