In 103 (72%) of 143 investigated patients had incomplete internal rectal fistula the fistulous holes with diameter less than 3 mm, and in the remaining 40 (28%) – from 3 mm to 25 mm. In 30 (21%) cases revealed inflammatory changes in the fistula hole, in 6 (4,2%) observed overgrowth of granulation tissue, and in 3 (2,1%) – scarring in anal canal fistula around hole area.

The most effective methods of examination patients with incomplete internal rectal fistulas are intrarectal fistulography and transrectal ultrasound (TRUS), which is often possible to obtain reliable information about the fistula structure. We have developed a device for fistulography with incomplete internal rectal fistula that was tested in 37 patients. Proposed fistulography was informative in 91,9% of cases, on the contrary, when the well-known method fistulography – 16,4%.

Using TRUS a classification of incomplete internal fistula rectum by its complexity is developed, which provides sufficient information about the nature and structure of the fistula.

Keywords: incomplete internal fistula, fistulography, transrectal ultrasonography.
