Influence of seton configuration, thickness, and laxity on patient comfort in chronic perianal fistula: a prospective comparative study.
Article in International journal of colorectal disease, 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
purposeTo determine how seton configuration, thickness, and laxity influence patient comfort and clinical outcomes in the management of chronic perianal fistulas.
methodsA prospective single-center study was conducted involving 33 patients (53 setons). Both intraindividual paired (n = 20) and independent group analyses (n = 13) were performed. Setons were categorized by configuration (O-shaped vs. V-shaped), thickness (1.5 mm vs. 2.5 mm), and laxity (≤ 2 cm vs. > 2 cm from the anal verge). Patient-reported outcomes were assessed using structured questionnaires evaluating sitting discomfort, discharge, sexual impact, and fecal incontinence.
resultsO-shaped setons caused significantly less sitting discomfort than V-shaped ones (50.0% vs. 80.0%, p = 0.021). Excess laxity (> 2 cm) was associated with increased discharge (86.4% vs. 51.6%, p = 0.008), sexual impact (42.1% vs. 10.3%, p = 0.016), and fecal incontinence (66.7% vs. 10.0%, p = 0.041). Thicker setons (2.5 mm) showed a non-significant trend toward more pain (42.9% vs. 17.9%, p = 0.080).
conclusionSeton configuration and laxity significantly affect patient comfort. O-shaped setons and shorter laxity (≤ 2 cm) are preferable for reducing discomfort. These findings support evidence-based seton selection, although larger multicenter studies are needed to confirm these results.
