[Complications of colostomies. Follow-up study of 500 colostomized patients].

The complications of colostomies may constitute a handicap for patients: their prevalence severity and methods of treatment remain poorly known. 500 colostomy patients, with a mean age of 66 +/- 14 years, were retrospectively reviewed. The mean follow-up of the study was 6 +/- 5 years. Colorectal cancers represented 65% of the initial diseases. 59.5% of colostomies were terminal. They were performed for resection of the colon and or rectum in 56.5% of cases. 30.5% of patients (n = 152) presented complications (n = 235). The early complications (n = 147) observed in 29.5% of patients were mostly benign (20 required emergency operations). The late complications (n = 88), observed in 22.5% of 391 patients with a follow-up of more than one year required another operation in 1/3 of cases (11 cases of stenosis, 9 incisional hernias and 8 prolapses). Complications of colostomies remain frequent (one out of every 4 stomies ends in a complication) and the reoperation rate is situated between 13 and 33%. The therapeutic success rate of late reoperation is between 63 and 74%. When a reoperation is necessary, it should be ideally radical via a midline incision. The transposition technique gives better results than the repositioning technique via a local approach.
