超声引导下穿刺活检术在人体实质脏器应用已日趋完善,对空腔脏器胃肿瘤进行经皮胃活检的研究在国内报道甚少。为了拓宽超声介入诊断范围,弥补纤维胃镜粘膜活检局限性的不足,我们自1996年开始对超声高度疑诊胃肿瘤,而其它影像学检查阴性或胃镜活检阴性的病例进行超声引导下经皮 Ultrasound-guided puncture biopsy has gradually improved the use of human visceral organs, and the study of percutaneous gastric biopsy of cavificent organ stomach tumors has rarely been reported in China. In order to broaden the scope of ultrasound interventional diagnosis and make up for the limitations of mucosal biopsy of fiberoptic gastroscopy, we have been highly suspicious of suppurative gastric tumors since 1996, and ultrasound-guided percutaneous imaging has been performed on other imaging negative or endoscopically biopsy-negative cases.
