For many patients, anal incontinence (AI) is a devastating condition that can lead to social isolation and loss of independence, contributing to a substantial economic health burden, not only for the individual but also for the allocation of healthcare resources. Its prevalence is underestimated because of poor patient reporting, with many unrecorded but symptomatic cases residing in nursing homes. Endosonography has improved our understanding of the incidence of post-obstetric sphincter tears that are potentially suitable for repair and those cases resulting from anorectal surgery, most notably after fistula and hemorrhoid operations. The clinical scoring systems assessing the severity of AI are discussed in this review, along with their limitations. Improvements in the standardization of these scales will advance our understanding of treatment response in an era where the therapeutic options have multiplied and will permit a better comparison between specific therapies.
