The Essential Role of High-resolution MRI Fistulogram Imaging with Ultrasound Gel Enema in Diagnosing Complex Rectovaginal Fistulas Post-Chemoradiation for Rectal Cancer: A Case Study Review.
Review in Current medical imaging, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundRectovaginal fistula (RVF) is a rare and severe complication that may follow chemoradiation treatment of rectal cancer. The limitations of traditional imaging modalities are due to the diagnostic difficulty of rectovaginal fistula (RVF) caused by vague symptomatology. However, because pelvic MRI fistulogram offers better contrast in soft-tissue and multi-planar image viewing, which are very important for accurate diagnosis and efficient treatment planning, it has become the ultimate choice for the evaluation of RVF. CASE PRESENTATION: A 36-year-old female who had previously been diagnosed with rectal cancer and had undergone a chemoradiation regimen experienced a clinical response to treatment. Subsequently, she returned to our office with complaints of new-onset pelvic pain. The patient underwent a high-resolution pelvic MRI fistulogram using an ultrasound gel as an enema agent. The imaging revealed a well-defined fistulous tract between the rectum and vagina, with uncertain residual mural thickening, which significantly impacted her clinical course.
conclusionThis case demonstrates how to use high-resolution ultrasound gel to visualize an undetected rectovaginal fistula and reinforces the importance of this technique in understanding associated disorders and helping the interdisciplinary team make decisions regarding RVF.
