Autologous Myoblast Intrasphincteric Injection for Fecal Incontinence (MIAS)

This project aims to offer autologous muscle-derived progenitor cell injection as an efficient mini-invasive surgical therapy that would be simple for the patient and could be used in a majority of cases, including in young women in the post-partum. This approach may provide efficient tissue repair of the striated anal sphincter which is not permitted by existing therapies. This innovative therapy may ultimately be proposed after failure of the common treatments and before an high-risk invasive surgical intervention. Besides, injection of muscle-derived progenitor cells in animals has shown very encouraging results of the sphincter function assessed ex vivo. Hence, a high benefit may be expected with this approach.

Arms Assigned Interventions
Active Comparator: myoblast injection
autologous myoblast
Other: Myoblast injection
Autologous myoblast injection in the anal sphincter
Placebo Comparator: saline solution injection

Procedure: saline solution injection
saline solution injection in anal sphincter

Detailed Description:

after verification of information and inclusion criteria. patients were randomized to treatment or placebo arms and receive the injections.

an evaluation of the function and quality of life are realized. after a period of 6 months, patients in the placebo arm receive the injection of myoblasts that have been preserved.
