Endoanal ultrasonography in XXXX : Current and future perspectives.

@entity1 @entity1241 @entity1690 @entity130
@entity1241 has a profound impact in a @entity1 's life, impairing quality of life and carrying a substantial economic burden due to health costs. It is an underdiagnosed condition because many affected @entity1 are reluctant to report it and also clinicians are usually not alert to it. @entity1 evaluation with a detailed clinical history and examination is very important to indicate the @entity130 that is present. Endoanal ultrasonography is currently the gold standard for sphincter evaluation in @entity1241 and is a simple, well-tolerated and non-expensive technique. Most studies revealed 100% sensitivity in identifying sphincter defect. It is better than endoanal magnetic resonance imaging for internal anal @entity1690 , equivalent for the diagnosis of external anal @entity1690 , but with a lower capacity for assessment of atrophy of this sphincter. The most common cause of @entity1241 is @entity130 related to @entity130 . Only a small percentage of @entity1 are diagnosed with sphincter tears immediately after vaginal delivery, but endoanal ultrasonography shows that one third of these @entity1 have occult @entity1690 . Furthermore, in @entity1 submitted to primary repair of these tears, ultrasound revealed a high frequency of persistent @entity1690 after surgery. Three-dimensional endoanal ultrasonography is currently largely used and accepted for sphincter evaluation in @entity1241 , improving diagnostic accuracy and our knowledge of physiologic and pathological sphincters alterations. Conversely, there is currently no evidence to support the use of elastography in @entity1241 .
