Anorectal Anomaly: Its Embryological and Genetic Basis

Anorectal anamolies consist of a wide spectrum of diseases, which can affect both boys and girls, and involve the distal anus and rectum along with the urinary and genital tracts. They are of three types: high, intermediate and low. The high type anorectal malformations are usually associated with congenital anomaly of other systems or organs .The present case is a normal male child born through spontaneous vaginal delivery but presented with failure to pass meconium and had no anal opening. The brief history taken & examinations performed helped in making the diagnosis of anorectal malformation, most probably imperforate anus. The present anamoly is discussed here with its anatomical & developmental basis.
