Modified fistulotomy with internal orifice distalization for optimized perianal fistula management: Pressure zone transition.
Article in World journal of gastrointestinal surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundBoth the etiology and treatment of perianal fistulas present challenges, and there is no standard surgical approach.
aimTo present the results of a modified fistulotomy technique that was implemented in a tertiary coloproctology reference center.
methodsSeventy-two patients who underwent surgical intervention for perianal fistula between August 2019 and January 2023 were treated using a modified fistulotomy technique. In this approach, the fistula tract was excised from the external opening up to the external sphincter fibers. The internal orifice was widened, and the septic focus within the inter sphincteric space was curetted. Partial internal sphincterotomy was performed up to the inter sphincteric plane. The anoderm from the internal orifice to the inter sphincteric space was closed with absorbable suture material, and a loose seton was placed at the level of the external sphincter.
resultsThe 72 patients who underwent modified fistulotomy were 77.8% male and 22.2% female, with a mean age of 42.2 ± 11.5 years. The median follow-up period was 19 months. Preoperatively, 93.1% of patients had high trans sphincteric fistulas, and 6.9% were females with anterior low trans sphincteric fistulas. In all cases, setons were placed during surgery using vascular tape. A total of 12.5% of patients experienced incontinence, involving gas (6.9%) or soiling (5.6%). There were no reports of solid or liquid incontinences. Complete healing was achieved in 83.3% of the patients, with a recurrence rate of 4.2% and a non-healing rate of 12.5%.
conclusionOur preliminary analysis suggests that this modified fistulotomy technique that targets distalization of the internal orifice is a promising alternative management strategy for perianal fistulas.
