Sphincter Atrophy

  • Richelle J. F. Felt-Bersma


The term “sphincter atrophy” refers mostly to external anal sphincter (EAS) atrophy, as the EAS is the most important factor for maintaining fecal continence. EAS atrophy, often due to pudendal neuropathy caused by stretch injury during childbirth [1] or chronic constipation [2, 3], is an important cause of fecal incontinence. When a woman is fecally incontinent and there is a history of a difficult childbirth with prolonged labor or chronic constipation as well as a sphincter rupture, there is always a chance that, besides the rupture, some atrophy is present in the EAS.
