PSARP
Pronunciation: P-SARP
Also written as: PSARP — Posterior Sagittal Anorectoplasty
A surgical approach for repairing anorectal malformations through the posterior sagittal plane to optimize anatomical reconstruction.
Full Definition
Posterior Sagittal Anorectoplasty (PSARP) is the standard surgical technique for definitive repair of most anorectal malformations, introduced by Alberto Peña. The procedure involves a posterior sagittal incision through the midline, dividing the external sphincter complex, levator muscles, and other pelvic structures to expose the rectum and surrounding anatomy. This approach allows optimal visualization for mobilizing the rectal pouch, dividing fistulous connections, and creating a neo-anus within the sphincter complex. The technique emphasizes preservation of nerve supply and muscle function while achieving anatomically correct reconstruction.
Usage
Usage note: Peña technique is the eponymous reference for this approach.
