Abstract
Faecal incontinence can severely affect quality of life, but as it has no influence on life expectancy, the long-term efficacy of any treatment must be taken into account.Most reports on new treatments for faecal incontinence describe short-term results and are rarely followed by a later review of the same group of patients; the few long-term reviews of traditional surgery are disappointing. The authors evaluated long-term outcome after implantation of an artificial bowel sphincter (ABS) (ActiconTM Neosphincter ABS; American Medical System, Minnetonka, Minnesota, USA) to determine whether the results tend to worsen with time. In the present study, obstructed defaecation was a frequent problem that led several patients to deactivate the pump. Together with the manometric findings of low anal canal resting pressure, even with the device activated, this suggests that the ABSmay function as a passive obstacle to the passage of faeces in the long term, like Thiersch’s sling, rather than as a dynamic sphincter. Furthermore, the ABS, like any foreign matter placed in the human body, may displace or erode, either to the rectum or to the perineum. Overall, the present study shows that the results of anal sphincter replacement using an ABS dynamic prosthesis deteriorate with time and that the long-term results may not be as good as reported previously.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
