Although endoscopic ultrasonography (EUS) represents a major advance in endoscopic imaging, endosonography using dedicated echoendoscopes has some serious drawbacks, including the diameter of the echoendoscope (12 to 13 mm), the lack of intraluminal examination of the pancreatobiliary duct system due to the size of the instrument, unsatisfactory image quality and resolution for small lesions, and the need for a second examination separate from the previous routine endoscopy. Recently developed ultrasonographic miniprobes (diameter, about 2 mm; frequency, 12 to 20 MHz) can be passed through the working channel of standard endoscopes to provide high-frequency ultrasound images. These miniprobes may overcome some of the noted drawbacks and add to the safety and convenience of patients. Moreover, in various diseases of the gastrointestinal tract and the pancreatobiliary ductal system, the diagnostic accuracy of miniprobe ultrasonography has been proven to be superior to that of EUS. Miniprobe ultrasonography is a promising tool that adds new capabilities to the armamentarium of gastroenterologic diagnostic assessment.
尽管内镜超声检查（EUS）是内镜成像领域的一项重大进展，但使用专用超声内镜进行的内镜超声检查存在一些严重缺陷，包括超声内镜的直径（12至13毫米）、由于器械尺寸导致无法对胰胆管系统进行腔内检查、对小病变的图像质量和分辨率不尽人意，以及需要在先前的常规内镜检查之外另行进行检查。最近开发的超声微型探头（直径约2毫米；频率12至20兆赫）可通过标准内镜的工作通道，以提供高频超声图像。这些微型探头可能克服一些上述缺陷，并增加患者的安全性和便利性。此外，在胃肠道和胰胆管系统的各种疾病中，微型探头超声检查的诊断准确性已被证明优于EUS。微型探头超声检查是一种很有前景的工具，为胃肠病诊断评估增添了新的功能。
