ABSTRACT
Congenital lower intestinal tract anomalies are significant cause of morbidity and mortality in children, classified in two groups, major one is anorectal malformation, other one Hirchsprung's disease, usually associated with other anomalies and should be treated as early as possible. To show the prevalence and our experience with congenital lower intestinal tract anomalies in AL-Najaf city. A total 50 patients had various types of congenital lower intestinal tract anomalies, 22 of them high types [anorectal] treated by 3 stages operations[preliminary colostomy, nearly new definitive surgery infracoccygeal approach and closure colostomy], minor surgery for low types [12] and for Hirchsprung's disease treated by usual pull through operation[Swenson's]. The anorectal anomalies [A.R.M] are the most common anomalies of lower intestinal tract, high type cases were 25, low type were 12 cases and Hirchsprung's disease were13 cases. Male were 30 cases and female were 20 cases, age of presentation between first day of life and 18 years of life. Infracoccygeal approach was the safe and non complicated operation in dealing with high type of anorectal malformation and the good results obtained when the operation was done early period of life [around one year]
