How to treat: Faecal incontinence

Faecal incontinence, not a glamorous area of medicine, has changed markedly in its recognition and management over the past 10 years. Patients and doctors can now talk about it because the taboo is disappearing. The pathophysiology is better understood, helped by advances in imaging. Treatments are improving as they move away from invasive sphincter surgery as an early step to the use of simple pharmacological treatments, behavioural techniques, injectable biomaterials, and, when necessary, minimally invasive surgery.

Faecal incontinence affects both sexes and all age groups. Approximately 2% of the adult population have it on a frequent basis.1 The commonest cause of faecal leakage is probably degeneration of the delicate smooth muscle of the internal anal sphincter--the muscle that maintains sphincter closure.2 The commonest cause in young women is obstetric anal sphincter damage.
