Patient selection
Women with anal incontinence unresponsive to conservative treatment with
a history of OASI or unrecognized/occult OASI as evident by endoanal
ultrasound were included in the study if they underwent a transvaginal
AS repair from July 2005 to July 2020. Women with concurrent
rectovaginal fistula and AS repair were excluded from the main results
and analysed as a separate group. Patients with inadequate data, and
those who failed to attend follow up were excluded from the study.
