Early evaluation of perineal anal transplant in low anorectal anomalies

ABSTRACT

The early postoperative results of perineal anal transplant operation were evaluated. The procedure was done in 22 neonates and infants with different types of low anorectal anomaly. Some modifications for the original procedure described by Swenson and Donnellan were performed.
