posterior sagittal anorectoplasty
Also written as: PSARP — posterior sagittal anorectoplasty
A surgical approach for treating anorectal malformations involving division through the posterior sagittal plane.
Full Definition
Posterior sagittal anorectoplasty (PSARP) is the standard surgical technique for repairing most types of anorectal malformations in children. Developed by Alberto Peña, this approach involves making an incision in the posterior sagittal plane, dividing the muscles, sphincter complex, and other structures in the midline to access the rectum and create a new anal opening. The procedure requires careful identification and preservation of the muscle complex while establishing proper anatomical relationships. PSARP allows for optimal visualization of the anatomy and precise reconstruction, leading to better functional outcomes in terms of bowel control and continence. The technique may be combined with other procedures depending on the specific type of malformation.
Usage
Usage note: Commonly abbreviated as PSARP; named after Alberto Peña who developed the technique.
