Minimal Lateral Internal Sphincterotomy (LIS): Is It Enough to Cut Less Than the Conventional Tailored LIS?
Article in Annals of coloproctology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
purposeAnal fissure is a common anorectal condition, yet its pathogenesis remains unclear. Lateral internal sphincterotomy (LIS) is the gold standard treatment for chronic anal fissures that do not respond to conservative treatment; however, it has a risk of anal incontinence. We believe that fibrosis of the internal anal sphincter is an important factor in the pathogenesis of chronic anal fissure. In this study, we describe the minimal LIS method, a minimally invasive method where only the fibrotic portion of the internal anal sphincter is cut. We also describe the outcomes of this method.
methodsWe performed a retrospective review of 468 patients (270 male and 198 female) who underwent minimal LIS for chronic anal fissure in 2017 at Seoul Song Do Hospital. We analyzed the patients' clinical characteristics, manometry data, complications, and outcomes of minimal LIS. The outcomes of the surgery were assessed via questionnaires during the postoperative outpatient visits, beginning 2 weeks postoperatively.
resultsThe overall complication rate was 4.0% (19 patients). Delayed healing occurred in 14 patients (3.0%), perianal abscess was present in 3 patients (0.6%), and gas incontinence occurred in 2 patients (0.4%). All complications were improved with conservative treatment. Recurrence, defined as the recurrence of anal fissure more than 4 weeks after healing, was present in 6 patients (1.3%).
conclusionMinimal LIS is a safe and effective treatment option for patients with chronic anal fissure. Postoperative complications, especially incontinence and recurrence, are rare.
