Repair of Anorectal Malformation

항문직장기형의 교정

Major advances in the management of anorectal malformations have been achieved during the last 20 years. Alberto Pena introduced the posterior sagittal anorectoplasty (PSARP) in 1982. He divided all the sphincteric muscles at the exact posterior midline and fully exposed the crucial anatomy. He was able to manage the associated fistula under direct vision with minimal urinary tract injury. The rectum could be placed in the middle of the sphincteric muscle complex. Even with PSARP by Alberto Pena himself, only 37.5% of all cases were considered totally continent. Anorectal malformation is still acontinuing challenge for the pediatric surgeons.
