Monocentric Feasibility Study for a New Medical Device for the Treatment of Anal Fissure With Botulinum Toxin

Anal Fissure Clinical Trial

Official title:
Étude Monocentrique de faisabilité d'un Nouveau Dispositif Pour le Traitement de la Fissure Anale Par Toxine Botulique (FR) Monocentric Feasibility Study for a New Medical Device for the Treatment of Anal Fissure With Botulinum Toxin (EN)

Clinical Trial Summary

Monocentric feasibility study for a new device for the treatment of anal fissure with botulinum toxin.

Clinical Trial Description

Anal fissure is a common anal disease. This is a longitudinal tear in the distal part of the anal canal. The fissure provokes a spasm of the internal anal sphincter and as such pain and eventually bleeding. There are currently 3 different treatments. All available treatments tend to relax the anal sphincter, which reduces pain and promotes fissure healing. The first treatment consists in the local application of cream into the anal canal. The second option is the injection of botulinum toxin into the internal or external anal sphincter. Finally the third option is a surgical intervention, most frequently a lateral sphincterotomy. Although the usefulness of botulinum toxin to treat anal fissure has been demonstrated, the results vary. This is most likely largely due to the fact that there is no standardized way to inject botulinum toxin and that there is a significant learning curve. In addition, the gesture is not without risk for the operator. The objective of the study is to assess the feasibility of injecting botulinum toxin into the anal canal with a new medical device for patients with anal fissure. The trial is a mono-centric pilot study conducted on 4 patients. The study is open, prospective and all patients will be treated with the botulinum toxin injected using the new medical device. The device (single-use) under investigation and the botulinum toxin will be made available free of charge to the patient. ;
