Details and patient eligibility

About

Aim:

To investigate efficacy and safety in a new treatment with injection of autologous muscle fibers into the anal sphincter in patients with fecal incontinence.

Method:

Patients with fecal incontinence after obstetric anal sphincter rupture will be included. After inclusion, they will be offered 3 months of pelvic floor muscle training. If the patients after completion of pelvic floor muscle training still suffer from fecal incontinence, the patients will be offered treatment with autologous muscle fiber injection into the anal sphincter. The patients will be followed one year after the injection. The autologous muscle fibers are harvested at the patients leg muscle, cut into small pieces and injected into the anal sphincter. A small part of the fibers are used for analysing number of muscle stem cells and thereby the regenerative potential of the sample.

The study is a pilot study.

Injection of autologous muscle fibers in the anal sphincter
Experimental group
Description:
All patients, that still have relevant symptoms after completion of three months with individualized pelvic floor muscle training and dietary intervention to control defecatory function, will be offered injection of autologous muscle fiber fragments in the anal sphincter. A myscle biopsy will be taken from the leg, cut into small pieces in a saline solution and injected in the anal sphincter.
Treatment:
Procedure: Injection of autologous muscle fibers into the anal sphincter.
Procedure: Pelvic floor muscle training
Behavioral: Dietary intervention
Drug: Analgesia
