[Efficacy of PTQ agent in the treatment of faecal incontinence]

Faecal incontinence caused by a weak or disrupted internal anal sphincter is common and the efficacy of current treatments for this condition is poor. This study evaluated the short- and long-term effects of injections of silicone biomaterials (PTQ) commonly used to increase anal internal sphincter resistance. A total of 16 patients with a mean age of 66 years affected by faecal incontinence with a low anal resistance to the pressure due to previous surgery of the pelvic region were submitted to intra-sphincteric PTQ injections. The effects of the treatment on the symptoms associated with faecal incontinence and on quality of life were evaluated with the American Medical System Score and with anal ultrasound at 3 months and one year after the procedures in comparison with the scores calculated at entry. At 3 months from the procedure, anal ultrasound confirmed that PTQ injections had been correctly performed without material migration to other regions. Faecal continence was significantly improved but more efficacy was found one year after the injections. The American Medical System Score calculated one year after the procedures was significantly improved in comparison with the scores calculated at entry. During the follow-up the Authors did not observe any significant complications. PTQ injections significantly improved faecal continence and consequently the quality of life of patients with sphincter dysfunctions.
