Seventy-seven colostomies were performed in 74 patients: 35 for high anorectal agenesis, 34 for Hirschsprung's disease, 2 for necrotizing enterocolitis, 2 for small left colon syndrome, and 1 for volvulus neonatorum with perforation. There were 55 boys and 19 girls with a mean age of 0.8 years. The different types of colostomies performed were: transverse loop in 48, sigmoid loop in 21, transverse end in 4, descending end in 2, sigmoid end in 1, and transverse double barrel in 1. Forty-seven patients developed stomal complications (74.6%). Eleven patients died, but only in 2 (2.7%) were the deaths directly related to colostomy formation. Five patients required stomal revision (6.8%). The incidence of complications was neither related to the age nor to the primary indication for the colostomy, but sigmoid colostomy was associated with a lower complication rate compared to transverse colostomy (52% versus 81% 0.02 greater than p greater than 0.01). A sigmoid loop colostomy should be used whenever possible.
