ANORECTAL STENOSIS IN A NEONATE - REPORT OF A CASE AND REVIEW OF THE JAPANESE LITERATURE

We report herein the case of an infant with anorectal stenosis success fully treated by staged surgery., At 1 day of age, the anal orifice sh owed circumferential stenosis located 5 mm from the anal verge and ext ending into the anal canal for approximately 1 cm; however, no hypertr ophic raphe or bucket handle appearance were observed, and no associat ed anomalies such as a presacral mass or sacral dysgenesis were found. At 2 days of age, the infant underwent a sigmoid colostomy under the diagnosis of low anorectal stenosis, followed by a successful anorecto plasty, performed through a sacroperineal approach when he was 8 month s old, An analysis of 13 other cases of anorectal stenosis from the Ja panese literature indicates that this type of malformation should be t reated by staged surgery, as an initial colostomy in the neonatal peri od, followed by anorectoplasty through a sacroperineal approach during infancy.
