小探头超声在消化道疾病中的临床应用

目的：提高消化道粘膜隆起病灶的确诊率及肿瘤浸润深度判断。方法：于内镜检查时发现的12例病灶同时进行小探头超声（MPS）检查。结果：对粘膜隆起病灶及内镜下活检阴性的患者提供了有价值依据，对判断肿瘤浸润消化道壁深度MPS与手术后病理结果相符。结论：MPS对消化道粘膜隆起病灶性质鉴别优于常规胃镜及病理，对肿瘤浸润消化道壁深度能作出正确判断，但对较大病灶整体图像显示，周围淋巴结及邻近脏器有无转移是有限的。

Clinical Use of Miniprobe Sonography(MPS) in the Diagnosis of Gastrointestinal Diseases

Objective To raise diagnostic rate of protruded lesion of gastrointestinal mucosa and to judge the precise differentiation to the depth of malignant lesion.Methods 12 cases of gastrointestinal diseases were examined by MPS combined with endoscopic examination.Results To the patients suffering protruded lesion of gastrointestinal mucosa with negative biopsy,the MPS provided a sound basis for diagnosis;To the cases of malignant lesion,findings of MPS with regard to the depth were in total concordance with that of surgical biopsy.Conclusion MPS is significanfly superior to conventional endoscopy with pathological biopsy in the differentation of protruded lesion of gastrointestinal mucosa.But in the case of malignant lesion,only the depth of infiltration of gastrointestinal wall can be correctly assessed by MPS.The value is limited in showing whole Picture for larger focus and in the identification of around lymphnodes and whether or no distal metastases in the near organs.
