Feasibility and safety of intersphincteric incision and fistula ligation for the treatment of transphincteric anal fistula.
Article in BMC surgery, 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
backgroundTo evaluate the clinical efficacy and safety of intersphincteric incision and fistula ligation in the treatment of transphincteric anal fistula.
methodsThis retrospective study analyzed the clinical data of 84 patients with transphincteric anal fistula who underwent intersphincteric incision and fistula ligation at the National Center for Colorectal Disease Treatment, Nanjing Hospital of Chinese Medicine Affiliated to Nanjing University of Chinese Medicine from January 2024 to October 2024. Cure rates, pre- and postoperative Wexner anal incontinence scores, and postoperative complications were recorded.
resultsAmong the 84 patients, 77 [91.67%, 95% confidence interval (CI) = 84.63-96.77) were cured after a single surgery. The pre- and postoperative Wexner anal incontinence scores of all patients were unchanged (P = 0.483). Of the 84 patients, six patients (7.1%, 95% CI = 2.7-14.9) experienced postoperative urinary retention, with no cases of postoperative bleeding or incision infection. No patients who only underwent intersphincteric incision and fistula ligation exhibited postoperative "lock-eye" deformity of the anus. Postoperative pain was uniformly mild, and full satisfaction with outcomes was reported.
conclusionsThe combination of intersphincteric incision and fistula ligation for transphincteric anal fistula offers high cure rates, good anal function protection, and low postoperative complication rates, reflecting a safe and effective strategy worthy of clinical promotion.
