Endoscopic ultrasonography (EUS) was evaluated in the diagnosis of carcinoma of the papilla of Vater. Thirteen cases of carcinoma of the papilla examined by EUS were investigated with the aim of assessing the detection capability of EUS in comparison with other diagnostic tools, and its usefulness in diagnosing the extent of the tumor. The EUS image of the normal papilla of Vater presents as a round protruded region with the layered structure of the duodenal papilla along with images of periampullary organs. All but one of 13 tumors of the duodenal papilla presented as a hypoechoic solid mass at EUS. On the basis of an analysis of the layered structure of the papilla of Vater and/or the duodenal wall, EUS images of 12 cases of ampullary carcinoma confirmed histologically were analysed. The EUS images of the tumors of the duodenal papilla corresponded well with the histological findings. When the extent of carcinoma was classified in 4 stages by EUS, the accuracy rate was 83%. EUS is one of the most promising procedures for determining the extent of tumors of the duodenal papilla.
对内镜超声检查（EUS）在诊断 Vater 壶腹癌方面进行了评估。对 13 例经 EUS 检查的 Vater 壶腹癌病例进行了研究，目的是评估 EUS 与其他诊断工具相比的检测能力，以及其在诊断肿瘤范围方面的实用性。正常 Vater 壶腹的 EUS 图像表现为一个圆形突出区域，伴有十二指肠乳头的分层结构以及壶腹周围器官的图像。13 例十二指肠乳头肿瘤中，除 1 例之外，其余在 EUS 上均表现为低回声实性肿块。基于对 Vater 壶腹和/或十二指肠壁分层结构的分析，对 12 例经组织学证实的壶腹癌的 EUS 图像进行了分析。十二指肠乳头肿瘤的 EUS 图像与组织学结果吻合良好。当通过 EUS 将癌的范围分为 4 期时，准确率为 83%。EUS 是确定十二指肠乳头肿瘤范围最有前景的检查方法之一。
