Abstract

A fiber-optic endoscopic instrument (Fistuloscope) is used to visualize anorectal fistula, and to accurately identify the course through the fistula. The instrument can be used to flush the fistula, to close the fistula tract by means of injecting sealants or placing grafts in the tract of the fistula or to pass setons, micro-instruments or other means to treat and seal the tract. A plug in the form of a graft can be inserted into the tract of the fistula.
