The endosonographic anatomy of the anal sphincters was studied by in vivo and in vitro correlation with anatomical dissection. Fourteen fresh anorectal specimens (eight abdominoperineal resection, six post mortem) were scanned in a water-bath with sequential dissection and correlation with the ultrasonographic images. Accurate anatomical identification of the layers during dissection was confirmed histologically. Anal endosonography was performed during operation in 12 patients to validate the in vitro findings. The in vivo study confirmed the in vitro results. Basic endosonographic anatomy has been clarified and inaccuracies in the previous description of the longitudinal muscle and external anal sphincter corrected.
通过体内和体外与解剖学解剖的相关性研究了肛门括约肌的腔内超声解剖结构。对14个新鲜的肛肠标本（8个经腹会阴切除术标本，6个尸检标本）在水浴中进行扫描，并进行连续解剖，使其与超声图像相对照。解剖过程中各层的准确解剖识别通过组织学得到证实。对12例患者在手术过程中进行了肛门腔内超声检查，以验证体外研究结果。体内研究证实了体外研究结果。基本的腔内超声解剖结构已得到阐明，并且纠正了先前对纵肌和肛门外括约肌描述中的不准确之处。
