Figure 3 A 35-year-old male patient with a suprasphincteric anal fistula managed by transanal opening of intersphincteric spaceprocedure. A: Axial section (Schematic diagram); B: Coronal section (Schematic diagram); C: Preoperative photograph; D: Preoperative T2-weighted magnetic resonance image (MRI) axial section; E: T2-weighted preoperative MRI coronal section; F: Postoperative photograph showing the transanal opening of intersphincteric space wound, the laid open intersphincteric portion of the fistula tract, in the anal canal; G: Postoperative T2-weighted MRI axial section 3 mo after surgery showing healed fistula tracts; H: Postoperative T2-weighted MRI coronal section 3 mo after surgery showing healed fistula tracts; I: Postoperative photograph showing the final picture and a tube inserted in the tract in right ischiorectal fossa. The tube was sutured to the skin with monofilament non-absorbable 2-0 nylon. Orange arrows show fistula tracts.
