High-intensity focused ultrasound rectoanal lifting (HIFU-RAL) for prolapsed hemorrhoids: a case series.
Article in Journal of surgical case reports, 2025. 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
Prolapsed hemorrhoids can affect quality of life, owing to associated pain and other symptoms. Although hemorrhoidectomies are curative, postoperative complications such as pain, bleeding, and delayed recovery are unavoidable. Some patients cannot undergo surgery due to comorbidities or social factors. These challenges highlight the need for minimally invasive, immediate treatments. This study explored the effectiveness of high-intensity focused ultrasound rectoanal lifting (HIFU-RAL) in 10 patients with grade IV hemorrhoids. The procedure was completed within 13.5 ± 3.2 min. Immediately afterward, the prolapsed lesions visibly shrank or disappeared. No prolapse was observed between 9 days and 3 months following HIFU-RAL, and no adverse events were reported. Heating induced by HIFU may have triggered contraction of the longitudinal muscles, repositioning the hemorrhoids to their anatomical location and visually reducing the prolapsed lesion. HIFU-RAL is a promising, minimally invasive treatment for prolapsed hemorrhoids that can be performed immediately in a consultation room.
