Colostomy is a common procedure in children and may be attended by many complications. The aim of this study was to review the complications of colostomy formation in a consecutive series of infants and children with a disorder necessitate formation of colostomy. A prospective study of complication associated with the formation of colostomy in children between May 2011 and April 2013, at the Khartoum Teaching Hospital, Khartoum, Sudan. There were 88 children, their mean age was 9.96 months (Range: 1 day to 7.8 years). The male to female ratio was 3.6:1. The indications for colostomy were Hirschsprung's disease in 46 (52.3%), anorectal malformation in 37 (42%) and severe perineal trauma in 1 (1.1%). Complications after colostomy formation were encountered in 28 (31.8%) patients and the commonest complication was stenosis 10 (11.4%), followed by skin excoriation 4 (4.5%) and obstruction 4 (4.5%). A significant number of colostomies in children is constructed largely due to Hirschsprung's disease. In spite the improvement in surgical practice in our environment, the incidence of complication following colostomy in pediatric still high.
