Platelet‐rich plasma improves acute and chronic anal fissure, a randomized control trial

Anal fissure is one of the most prevalent diagnosis in patients with anorectal symptoms. Depending on the chronicity, treatment choices vary, from topical and conservative management to operative ones. PRP is a blood‐derived product with a three to five‐fold 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 weeks, 1 month, and 6 months later. The mean pain score in the intervention group was significantly lower than control groups in all visits (p‐value
