Internal Orifice Alloy Closure: A New Procedure for Treatment of Perianal Fistulizing Crohn's Disease.
Article in Medical science monitor : international medical journal of experimental and clinical research, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
BACKGROUND The high recurrence rate of perianal fistula Crohn's disease (PFCD) increases the need to protect the anal sphincter during each surgical treatment of fistulas. We aimed to evaluate the safety and efficacy of internal orifice alloy closure in patients with PFCD. MATERIAL AND METHODS Fifteen patients with PFCD were enrolled in the study between July 6, 2021, and April 27, 2023. All patients underwent preoperative colonoscopy and anal magnetic resonance examination for diagnosis and evaluation. Internal orifice alloy closure (IOAC) was performed only when Crohn's disease was in remission. The external sphincter had not been severed. Perianal magnetic resonance imaging examination was used for postoperative evaluation after 6 months. Fistula cure rate, length of stay, perianal pain, and Wexner incontinence score were retrospectively compared between 15 patients treated with IOAC and 40 patients treated with other surgical methods. RESULTS Fifteen patients (male/female: 9/6, age: 23.6±14.3 years) with PFCD were included (follow-up: 24 months). In total, 20.0% (3) had multiple tracts, and 13.3% (2) had a high anal fistula. Among them, 10 patients received biologics for induction for mucosal healing before surgery. The fistula healed completely in 80.0% (12/15) and did not heal in 20.0% (3/15). Three patients who did not heal underwent fistulotomy and eventually recovered. IOAC is not superior in terms of fistula healing rates, length of stay, and anal pain, but its Wexner incontinence scores are significantly lower than with other surgical methods. CONCLUSIONS IOAC is a novel sphincter-saving surgery that is effective and safe for the treatment of PFCD.
