Experimental
Anal fistula plug
The anal fistula plug procedure was performed as followings. A fistula probe was used to identify fistula tracts, and internal and external openings. Gentle mechanical debridement was performed with a blunt curette to remove the necrotic tissue with care not to enlarge the track, then hydrogen peroxide and sterile saline were used to repeatedly to irrigate the fistula. The anal fistutla plug was filled into the fistula, and sutured with a figure-of-eight 2-to-0 Vicryl suture to ensure the plug was fixed in the internal opening of the fistula, avoiding the anal fistula plug being extruded. Trimming the plug at the external fistula and the external opening was left open to ensure adequate drainage.
