Summary
Vaginal cytology can help diagnose rectovaginal fistulae by identifying colonic cells. This diagnostic method was successful in 65% of patients, aiding in the detection of fistulae caused by various conditions.
Area of Science:
- Gynecologic Pathology
- Colorectal Surgery
Background:
- Rectovaginal fistulae (RVF) present a diagnostic challenge.
- Vaginal cytology is a minimally invasive diagnostic tool.
Purpose of the Study:
- To evaluate the utility of vaginal cytology in diagnosing rectovaginal fistulae.
- To identify specific cytologic findings indicative of RVF.
Main Methods:
- Analysis of vaginal smears from 23 women diagnosed with rectovaginal fistulae.
- Histopathologic correlation and identification of colonic cells, fecal material, and malignant cells.
Main Results:
- Benign colonic cells were identified in 13 cases (56.5%).
- Fecal material was present in 7 cases (30.4%), with colonic cells in 5 of these.
- Malignant cells, indicative of colonic adenocarcinoma, were found in 2 cases (8.7%).
- Overall, RVF were documented via vaginal cytology in 65% of patients.
Conclusions:
- Vaginal cytology is a valuable adjunct in diagnosing rectovaginal fistulae.
- Identification of colonic cells and fecal material in vaginal smears supports RVF diagnosis.
- Cytologic evaluation can also detect associated malignancies in cases of RVF.
