Complications of colostomies.

One hundred twenty-six patients underwent 130 end colostomies, 44 for benign and 86 for malignant disease, and were followed for an average of 35 months. The left or sigmoid colon was used in 99 and the transverse colon in 31. Stomas were made electively in 98 patients and urgently in 32. Seventy-six stomas were brought out through the incision and 54 from separate sites. There were 69 complications in 55 patients (44 percent) including 11 strictures, 9 wound infections, 14 hernias, 9 small-bowel obstructions, 4 prolapses, 2 abscesses, 1 peristomal fistula, 17 skin erosions, and 2 poor stoma locations. Fifteen complications required reoperation. Five of these procedures included stoma revision. Total numbers of complications were not related to the stoma site, the disease process, the urgency of the procedure, or the segment of colon used. Wound infections, however, were increased in urgently made stomas. The incidence of hernia was equivalent in stomas brought out through the incision or at a separate site. Forty-one patients (30 percent) had 43 colostomies closed an average of 3.5 months after creation. Thirteen patients had 14 complications--5 wound infections, 6 hernias, 2 small-bowel obstructions, and 1 rectovaginal fistula. One patient died. Four patients required reoperation. There were no anastomotic leaks. Complications were equivalent in Hartmann closures and transverse colostomy closures. Complications were similar in stomas created for cancer and those created for diverticular disease.
