Congenital pouch colon with imperforate anus; a report of 3 cases

ABSTRACT

Congenital pouch colon [CPC] is an unusal condition in imperforate anus [IA] usually of high variety this malfotmation is mostly reported from India, where it comprises about 7% of all anorectal malformations. In this anomaly the normal colon is very short or absent and is replaced by a pouch like dilatation that usually communicates through a fistula with genitourinary tract or persistent cloaca. We are reporting on three cases of newborns [2 females, and 1 male] with this anomaly diagnosed during September 2001 to September 2004 These three cases comprise less than 3% of all cases of IA during this time period. The two girls had anorectal agenesia, short segment of colon and a pouch with vaginal fistula and persistent cloaca [Type II]. Colon in the third case was replaced by a dilated pouch that communicated with a wide fistula to the bladder [Type I]. This is very important for pediatric surgeons to be aware of the features of this condition to allow for proper diagnosis and surgical management
