摘要

Background and aims Congenital pouch colon (CPC) is an extremely rare variant of anorectal malformation (ARM), in which varying lengths of the colon is replaced by a dilated pouch accompanied by a fistula communicating with the genitourinary tract. The aim of this study was to determine the incidence and prevalence of various forms of CPC and to classify it according to anatomic localization of malformation.
