- W2034803062 abstract "Extensive damage of the pelvic floor due to childbirth can lead to anatomical abnormalities such as levator defects and or anal sphincter injuries. This study was designed to investigate their incidence and prevalence in patients complaining of pelvic organ prolapse and or fecal incontinence with transperineal ultrasound. Some 164 patients were included in a prospective observational study. Transperineal ultrasound was performed in the supine position after voiding acquiring 3D/4D volumes at rest, contraction and on Valsalva using a GE Kretz Voluson 730 Expert system. For imaging of the anal sphincter complex a 3D microconvex transducer (RNA 5–9-MHz) was used. Offline analysis was performed with 4D View software with the investigator blinded to the clinical data. For quantification of the levator defects tomographic ultrasound imaging (TUI) was used. At the level of minimal hiatal dimension a set of eight slices with an interval of 2.5 mm was examined, and defects were scored from 0 to 8 for each side. The proportional difference (value rest − value contraction/value rest) for contraction was calculated for evaluation of pelvic floor function. Forty-eight patients were diagnosed with an anal sphincter injury (29%), which involved the internal sphincter, external sphincter or both. A total TUI score of 10 was found in patients with anal sphincter injuries in contrast with a total score of 7.5 in patients without defects (P < 0.001). Of the 48 patients with sphincter defects only 17 complained of fecal incontinence (35%), compared with 28 (24%) without any sphincter defect (NS). No significant differences were found for age, mode of delivery or birth weight, hiatal measurements and the proportional difference of contraction. Patients with anal sphincter injuries have significantly more defects of the levator ani muscle but no higher incidence of fecal incontinence." @default.
