In short
Currently, there is 1 ongoing clinical trial investigating new treatment approaches for anal fissure. This study is exploring the use of ultrasound-guided Botulinum Toxin A injections for patients with chronic anal fissure who have not responded to standard treatments.

Study on Treating Chronic Anal Fissure in Patients Using Ultrasound-Guided Injections of Botulinum Toxin A
This clinical trial is investigating a new approach to treating chronic anal fissure, a condition where a tear in the lining of the anus persists for an extended period, causing ongoing pain and discomfort. The study is being conducted in Spain and focuses on improving the precision and safety of Botulinum Toxin A injections by using ultrasound guidance.
Who can participate:
- Adults of legal age who can provide informed consent
- People diagnosed with a chronic anal fissure that has lasted more than 6 weeks
- Patients whose condition has not improved despite trying various treatments including hygiene changes, dietary adjustments, relaxing treatments, or medications such as nitroglycerin or calcium blockers
- Those whose fissure shows signs of being chronic, such as hardened edges, visible internal anal sphincter fibers, or a sentinel polyp that has persisted for more than 6 weeks
- Both men and women are eligible to participate
Who cannot participate:
- Individuals who do not have a chronic anal fissure
- People outside the specified age range for the study
- Vulnerable populations who cannot give informed consent
What the trial involves:
The main goal of this study is to determine whether using ultrasound guidance to precisely locate the injection site makes Botulinum Toxin A treatment more effective and safer than the standard injection method. Botulinum Toxin A works by relaxing the muscles around the fissure, which helps reduce pain and allows the tear to heal.
Participants will receive injections of Botulinum Toxin A that are guided by an endorectal ultrasound probe. This imaging technique helps doctors see exactly where to place the injection, potentially improving treatment outcomes. The medication is prepared as a powder that is mixed into a solution before injection.
Throughout the study, participants will be monitored for changes in their symptoms and any side effects. Doctors will assess pain levels, check for any issues with bowel control, evaluate quality of life, and measure changes in the anal sphincter muscle using ultrasound. Regular follow-up appointments will be scheduled to track progress and address any concerns.
Investigational drug:
The study uses Botulinum Toxin A, a substance that blocks the release of chemicals that cause muscle contractions, leading to muscle relaxation. In the context of chronic anal fissure, this relaxation helps reduce pain and promotes healing of the tear. The trial specifically investigates whether ultrasound-guided injection of this medication provides better results than traditional injection methods.
Summary
Currently, there is one active clinical trial for chronic anal fissure, taking place in Spain. This study represents an effort to refine existing treatment approaches by incorporating ultrasound guidance to improve the precision of Botulinum Toxin A injections. The trial is particularly aimed at patients who have not found relief through conventional treatments and focuses on both the effectiveness and safety of this enhanced injection technique. The study employs comprehensive monitoring methods including pain assessment scales, quality of life measurements, and ultrasound imaging to evaluate treatment outcomes.
