目的：探讨上消化道隆起性病变的超声内镜表现特点。方法对常规胃镜发现的464例上消化道隆起性病灶，根据病灶特征，选择不同扫查频率进行超声内镜或者微型探头扫查，并进行归纳分析。结果464例上消化道隆起性病变中，食管病变145例（31．3％）、胃病变256例（55．2％）、十二指肠病变63例（13．6％）；超声内镜检查结果显示病变来源于黏膜层2例（0．4％）、黏膜肌层102例（22．0％）、黏膜下层118例（25．4％）、固有肌层186例（40．1％）、外压56例（12．1％）；其中食管病变多位于食管上段、来源于黏膜肌层，胃病变多位于胃底、来源于固有肌层，十二指肠病变多位于降段、来源于黏膜下层。结论上消化道隆起性病变在不同部位分布的几率不同，其来源层次及性质各异，且存在多发表现。

Objective To evaluate the endoscopic ultrasonographic characteristics of elevated lesions of the upper digestive tract.Methods In total,464 patients diagnosed with elevated lesions located at the up-per digestive tract underwent endoscopic ultrasonography (EUS)or miniprobe endoscopic ultrasonography (mEUS)according to the lesional characteristics.Results Among 464 cases of upper digestive tract lesions, 145 cases (31.3%)had esophageal lesions,256 (55.2%)gastric lesions and 63 (13.6%)duodenal le-sions.EUS revealed that the lesions originated from mucosa in 2 cases (0.4%),mucosal muscularis in 102 (22.0%),submucosa in 118 (25.4%),inherent muscularis in 186 (40.1%)and external pressure in 56 (12.1%).Esophageal lesions were mainly located in the upper esophagus and originated from mucosal muscu-laris.Gastric lesions were dominantly observed at the bottom of stomach and derived from inherent muscularis. Duodenal lesions mainly occurred in the descending segment and originated from submucosa.Conclusions The elevated lesions in the upper digestive tract differed in terms of distribution frequency,origin and charac-teristics.Multiple elevated lesions could be noted in the upper digestive tract.
