EP34.10: Diagnosis of anal sphincter injury by transperineal ultrasound: technique and reliability
Year: 2023
Type: conference-abstract
Abstract: Describe the technique of transperineal ultrasound and its reliability in the diagnosis of anal sphincter lesions. We conducted a descriptive study from 1 January 2021, to 1 May 2021. We included all women who came to our consultation for pelvic ultrasound for any indication and agreed to participate in the study. During transperineal ultrasound, exploration of the anal sphincter was performed by the vaginal probe. We studied 61 women, of whom 26% were nulligravida and 46% had never given birth by Caesarean section. Ultrasound lesions of the anal sphincter (ULAS) were found in 54% of cases: discontinuity of the anal sphincter (13%), thinning of the internal anal sphincter (25%), asymmetry and thickening of the external anal sphincter (10%), and mucosal star anomaly (35%). Anal fissures and chronic constipation were an independent RF for the occurrence of asymmetry and thickening of the external anal sphincter (OR = 10.22, RR = 1.38, p = 0.004 and OR = 9.47, RR = 1.22, p = 0.02, respectively) and were a predictor of the occurrence of ULAS (OR = 3.6, RR = 2.25, p = 0.06 and OR = 2.35, RR = 1.62, p = 0.11, respectively). Hemorrhoids were an independent RF for the occurrence of asymmetry and thickening of the external anal sphincter (OR = 6.46; RR = 1.24; p = 0.02). Vaginal delivery was a RF for the occurrence of ULAS (OR = 1.41; RR = 1.2; p = 0.5). Transperineal ultrasound is an effective and accessible technique for the detection of ULAS.
