Depending on the chronicity, treatment choices vary, from topical and conservative management to operative ones. PRP is a blood\u2010derived product with a three to five\u2010fold platelet count and can be used for restorative purposes. The objective of this study is to assess the therapeutic effect of intralesional PRP in acute and chronic anal fissures and comparing it with the classic topical approach. We included 94 patients with acute and chronic anal fissures and divided them into intervention and control groups. Control patients were treated only with topical compounds, and the intervention group received one dose of intralesional autologous PRP plus the same classic treatment. We assessed patients 2\u2009weeks, 1 month, and 6 months later. The mean pain score in the intervention group was significantly lower than control groups in all visits (<jats:italic>p<\/jats:italic>\u2010value &lt;0.001). During the follow\u2010ups, the bleeding rate was significantly lower in the intervention group, so in the sixth month, the bleeding was 4% in the intervention group against 32% of the control (<jats:italic>p<\/jats:italic>\u2010value &lt;0.001). The healing rate assessed by examination was 96% in the intervention group against 66% in the control in the sixth month (<jats:italic>p<\/jats:italic>\u2010value &lt;0.001). Although there may be no significant difference in healing rate between groups in the acute anal fissure, the PRP group is significantly superior in the chronic setting. We concluded that in anal fissure treatment, PRP plus topical products are significantly superior to alone topical treatment.<\/jats:p>","DOI":"10.1111\/wrr.13103","type":"journal-article","created":{"date-parts":[[2023,6,21]],"date-time":"2023-06-21T07:50:28Z","timestamp":1687333828000},"page":"655-662","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Platelet\u2010rich plasma improves acute and chronic anal fissure, a randomized\u00a0control trial"],"prefix":"10.1111","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9848-2754","authenticated-orcid":false,"given":"Hamed","family":"Ebrahimibagha","sequence":"first","affiliation":[{"name":"Department of General Surgery Shahid Beheshti University of Medical Sciences  Tehran Iran"},{"name":"Clinical Research Development Center, Shahid Modarres Educational hospital Shahid Beheshti University of Medical Sciences  Tehran Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adel","family":"Zeinalpour","sequence":"additional","affiliation":[{"name":"Department of General Surgery Shahid Beheshti University of Medical Sciences  Tehran Iran"},{"name":"Clinical Research Development Center, Shahid Modarres Educational hospital Shahid Beheshti University of Medical Sciences  Tehran Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,7,8]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1055\/s-0035-1570390"},{"key":"e_1_2_10_3_1","volume-title":"Anal Fissures","author":"Jahnny B","year":"2020"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1055\/s-0037-1609026"},{"issue":"2","key":"e_1_2_10_5_1","article-title":"Non surgical therapy for anal fissure","volume":"2012","author":"Nelson RL","year":"2012","journal-title":"Cochrane Database Syst Rev"},{"issue":"1","key":"e_1_2_10_6_1","first-page":"pc08","article-title":"Lateral anal sphincterotomy for chronic anal fissures: a comparison of outcomes and complications under local anaesthesia versus spinal anaesthesia","volume":"11","author":"Manoharan R","year":"2017","journal-title":"J Clin Diagn Res"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.4103\/idoj.IDOJ_369_19"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1079-2104(98)90029-4"},{"key":"e_1_2_10_9_1","volume-title":"CADTH Rapid Response Reports.
