Vaginography--investigation of choice for clinically suspected vaginal fistulas.

Abstract

PURPOSE:

Vaginal fistulas are rare but can cause extremely distressing symptoms for patients and prove difficult to define anatomically. Barium studies have been reported as having a maximum sensitivity of only 34 percent for detection of vaginal fistulas. Vaginography is an alternative method for diagnosis and evaluation of suspected vaginal fistulas, which has been reported to have a sensitivity of 100 percent. We reviewed our total experience of vaginography to fully assess its capabilities.

METHODS:

Twenty-seven patients with clinically suspected vaginal fistulas were investigated with vaginography during a six-year period. Results of vaginograms were compared with final operative or clinical diagnosis and with results of other radiologic investigations.

RESULTS:

Vaginography successfully identified 19 of 24 fistulas, giving a sensitivity of 79 percent. In our series, barium enema was only able to identify 9 percent of fistulas arising from the colon.

CONCLUSIONS:

In this, the largest series of vaginograms, apparent reduction in sensitivity from the 100 percent quoted in earlier series to 79 percent probably represents a more accurate assessment of vaginography as a diagnostic investigation. Even allowing for this reduction, vaginography is still the most sensitive, economic, and informative investigation for identification and delineation of vaginal fistulas. We recommend that vaginography be the initial investigation of choice in patients with clinically suspected vaginal fistulas.
