Fecal incontinence can negatively affect the patient's occupational and social life. Until recently, most patients with severe anal incontinence unresponsive to conservative medical and/or surgical treatments underwent colostomy. Currently, these patients can benefit from one of the innovative techniques that have recently been developed. Thus, the artificial anal sphincter and dynamic graciloplasty are now available, each with specific indications. Both procedures achieve good functional results but complication and reintervention rates are not inconsiderable. Sacral neuromodulation represents an important advance due to its relative simplicity and because, through a period of test stimulation, patients who can definitively benefit from its application can be identified. Other techniques, such as injectable bulking agents or radiofrequency ablation are so recent that experience is limited and their role remains to be defined. Since these techniques are so novel and their economic cost is high, their use should be restricted to study groups with an anorectal physiology laboratory and within the context of clinical trials until experience shows whether or not their application can become widespread.
