Injection of botulinum toxin significantly increases efficiency of fissurectomy in the treatment of chronic anal fissures.

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
purposeWhile acute anal fissures can be treated with topical therapy to reduce sphincter hypertonia (e.g., isosorbide dinitrate, glyceryl trinitrate, diltiazem), chronic fissures may require more invasive instrumental therapy. Currently, the golden standard remains lateral internal sphincterotomy; however, this carries the long-term risk of faecal incontinence. Fissurectomy can be a valuable alternative, but is less efficient because of absence of correction of underlying hypertonia. In this study, we aim to evaluate the additional effect of injection of botulinum toxin during fissurectomy in the treatment of chronic anal fissures.
methodsA single-centre retrospective analysis of 293 isolated superficial fissurectomies with or without injection of botulinum toxin was performed, with pain relief as primary endpoint.
resultsThe majority of patients undergoing fissurectomy were women (65%, mean age 45.0 years vs. 35% men, mean age 48.3 years), often because of ventral fissures (30% in women vs. 8% in men). Fissurectomy resulted in resolution of complaints in 81.1%, while additional injection of botulinum toxin resulted in resolution in 90.1% (p < 0.05). Complication rate was identical between the two groups, mainly (flatus) incontinence (4.5% vs 4.9% with botulinum toxin) and post-operative bleeding (1.8% vs 2.5% with botulinum toxin).
conclusionInjection of botulinum toxin significantly increases the efficiency of fissurectomy in the treatment of chronic anal fissures without additional complications.
