PSARP
Pronunciation: P-SARP
Also written as: PSARP — Posterior Sagittal Anorectoplasty
Surgical approach for anorectal malformation repair using a posterior sagittal incision.
Full Definition
Posterior sagittal anorectoplasty (PSARP) is the gold standard surgical technique for repairing most anorectal malformations, developed by Alberto Peña in the 1980s. The procedure utilizes a posterior sagittal approach through the midline, dividing all muscle structures in the midline to expose the rectum and any associated fistulas. The technique allows for precise identification and preservation of important anatomical structures including the external sphincter, levator ani muscle, and puborectalis muscle while creating a new anal opening in the appropriate location. PSARP has revolutionized the treatment of anorectal malformations by providing excellent visualization and functional outcomes when performed by experienced surgeons.
Usage
Usage note: Developed by Alberto Peña; requires specialized training and experience for optimal outcomes.
