Core Tip
Core Tip: High-resolution direct hydrogen peroxide (HP)-enhanced magnetic resonance imaging (MRI) fistulography offers superior visualization of complex and recurrent fistula-in-ano. It enhances diagnostic accuracy for internal openings, fistula tracks, and perianal abscesses, surpassing physical examination, trans-perineal ultrasound, and low-resolution MRI. With high sensitivity, specificity, and interobserver reliability, HPMRI aids precise surgical planning, reducing recurrence rates. This technique represents a valuable advancement in the preoperative assessment of anorectal fistulas, combining enhanced soft-tissue contrast with detailed anatomical visualization to address diagnostic challenges in intricate cases effectively. Future standardization and training could improve accessibility and further validate its clinical utility.
