Abstract
The fistula in ano or perianal fistula is one of the common fistulae noted in routine surgical and clinical practice. It has the tendency to reoccur even after surgery, which is due to missed pathological tract or tissue during surgical exploration. An adequate pre-surgical mapping is a necessity for giving an excellent surgical outcome and choosing an appropriate surgical technique for treating various fistulas.
Highlights
The perianal region fistula is a pathological tract extending between the perianal skin and anal canal, commonly encountered in routine surgical practice [1]
The subtraction technique, dynamic contrast imaging, volume imaging, and percutaneous instillation of aqueous jelly into the perianal fistula tract are the latest advances in imaging perianal fistula
The radiologist’s role while interpreting the perianal fistula is to give detailed reports of the anal sphincter and fistula’s relationship, enabling the surgeons to perform the appropriate surgical treatment that significantly reduces the recurrence and possible surgical complications like fecal incontinence [7]. 75% of the surgery with Magnetic Resonance Imaging (MRI) as the pre-operative investigation reduces the recurrence of perianal fistula
Summary
The perianal region fistula is a pathological tract extending between the perianal skin and anal canal, commonly encountered in routine surgical practice [1]. Perianal fistula, Aqueous jelly, MRI contrast media The conventional fistulography was the imaging technique used for perianal region fistula evaluation with radio-opaque contrast media instillation.
