Abstract

Preoperative evaluation was made of the diagnostic value of endoanal ultrasound (EAUS) and endovaginal magnetic resonance imaging (EVMRI) in diagnosing anal sphincter defects as the cause of anal incontinence. Nineteen female individuals with anal incontinence were examined clinically with EAUS and with EVMRI at 1.5 T using a prostatic coil. The findings were evaluated independently and compared with findings at surgery. In diagnosing external anal sphincter defects, EAUS and EVMRI showed almost similar agreement with surgical findings, 12 (63%) out of 19 vs 11 (58%), respectively. Internal anal sphincter defects were equally detected by EAUS and EVMRI as compared with surgical diagnosis. There was considerable variation between radiologists in diagnosing defects by EVMRI. EAUS and EVMRI are equal in diagnosing anal sphincter defects.

摘要

对经肛门超声检查（EAUS）和经阴道磁共振成像（EVMRI）在诊断作为肛门失禁病因的肛门括约肌缺陷方面的诊断价值进行了术前评估。19名患有肛门失禁的女性个体接受了临床检查，采用前列腺线圈在1.5 T下进行EAUS和EVMRI检查。对检查结果进行独立评估，并与手术结果进行比较。在诊断肛门外括约肌缺陷方面，EAUS和EVMRI与手术结果的一致性几乎相似，19例中分别有12例（63%）和11例（58%）。与手术诊断相比，EAUS和EVMRI在检测肛门内括约肌缺陷方面效果相同。放射科医生在通过EVMRI诊断缺陷方面存在相当大的差异。EAUS和EVMRI在诊断肛门括约肌缺陷方面效果相当。
