Clinical anal examination, manometry (resting and squeeze pressures), and single-fiber electromyography were compared with endosonography of the anal sphincters in 14 patients with fecal incontinence. Technical aspects of the procedure and normal imaging of the puborectal muscle and both sphincters were defined. Defects in both sphincters were seen in nine patients. The defect is visualized as a clear discontinuity in the muscular ring. Compared with the conventional studies, anal endosonography gave significant information in six patients (four male patients after perianal surgery and two women), showing sphincter defects in five patients and integrity of the sphincters in another one. This information obtained by endosonography was important in understanding the type and extension of the lesion and deciding upon the surgical repair. Anal endosonography is an imaging technique of the sphincters that can assess their integrity in fecal incontinence.
对14例大便失禁患者的临床肛门检查、测压（静息压和收缩压）及单纤维肌电图与肛门括约肌的腔内超声检查进行了比较。明确了该检查方法的技术要点以及耻骨直肠肌和两个括约肌的正常影像学表现。9例患者可见两个括约肌均有缺损。该缺损表现为肌环的明显中断。与传统检查相比，腔内超声检查为6例患者（4例肛周手术后男性患者和2例女性患者）提供了重要信息，其中5例显示括约肌缺损，另1例显示括约肌完整。腔内超声检查所获得的这些信息对于了解病变的类型和范围以及决定手术修复方式具有重要意义。腔内超声检查是一种可评估大便失禁患者括约肌完整性的括约肌成像技术。
