The aim of the present review is to assess the efficacy and safety of puborectalis muscle (PRM) division in the treatment of anismus.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>PubMed, Scopus, Web of Science and the Cochrane Library were searched for studies that assessed the outcome of PRM division in the treatment of anismus. The main outcome measures were subjective improvement in ODS, decrease in the Wexner constipation score and ODS score, and complications, namely faecal incontinence (FI).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Ten studies (204 patients, 63.7% male) were included. The weighted mean rate of initial subjective improvement across randomized trials was 97.6% (95% CI 94%\u2013100%) and across nonrandomized studies it was 63.1 (95% CI 39.3%\u201387%). The weighted mean rate of 12\u2010month improvement across randomized trials was 64.9% (95% CI 53.3%\u201376.4%) and across nonrandomized studies it was 55.9% (95% CI 30.8%\u201381%). The weighted mean rate of FI across randomized trials was 12.1% (95% CI 4.2%\u201320%) and across nonrandomized studies it was 10.4% (95% CI 1.6%\u201319.3%). Male sex and unilateral PRM division were significantly associated with recurrence of symptoms after PRM division. Bilateral PRM division, posterior division, complete division and concomitant sphincterotomy were significantly associated with FI after PRM division.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The use of PRM division for treatment of anismus was followed by some initial improvement in ODS symptoms which decreased to &lt;60% 12\u00a0months after PRM division. The mean rate of FI after PRM division, namely 10%\u201312%, is a limitation of the technique. Further well\u2010designed trials are needed to verify the outcome of PRM division in the treatment of anismus.<\/jats:p><\/jats:sec>","DOI":"10.1111\/codi.16040","type":"journal-article","created":{"date-parts":[[2022,1,5]],"date-time":"2022-01-05T07:47:39Z","timestamp":1641368859000},"page":"369-379","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Systematic
