超声内镜对胃镜、结肠镜下发现黏膜下隆起性病变的调查分析

Endoscopic ultrasonography analysis of 420 cases with eminence lesions in the gastrointestinal tract

目的探讨超声内镜（EUS）检查对胃镜、结肠镜下发现黏膜下隆起性病变的诊断价值。方法对420例胃镜、结肠镜下提示消化道黏膜下隆起性病变行EUS检查患者的临床资料进行回顾性分析。结果420例消化道黏膜下隆起性病变中，食管病变129例，胃部病变235例，十二指肠病变29例，结肠病变27例。发生于消化道管壁本身的病变占85．00％（357／420），其中黏膜下肿物占73．10％（307／420），并以间质细胞瘤和平滑肌源性肿瘤最为多见，占60．24％（253／420），消化道壁外压迫及未发现病变者占14．52％（61／420），侵犯消化道的壁外病变2例，占0．48％（2／420）。结论EUS检查能清楚显示消化道壁的层次结构，对消化道隆起性病变具有准确的定位作用，并能提示病变的性质；同时发现结肠黏膜下隆起性病变发生率最低，这可能与结肠的黏膜结构有关。

Objective To evaluate the diagnostic value of endoscopic ultrasonography（EUS） in the eminence lesions of gastrointestinal tract. Methods The clinical data of 420 patients with gastrointestinal eminence lesions subsequently received EUS were analyzed. Results In 420 cases, 235 cases lesions were located in the stomach, 129 cases in the esophagus, 29 cases in the duodenum and 27 cases in the colon. Occurred in the wall itself of the digestive tract lesions was 85.00% （ 357/420 ）, and 73.10 % （ 307/420 ） of submucosal neoplasm, and gastrointestinal stromal tumor, leiomyoma or leiomyosarcoma was seen [ 60.24% （253/420） ]. Lesions was not found in the digestive tract wall external oppression and lesions accounted for 14.52%（61/420）, external lesions and infiltrated digestive tract was 0.48%（2/420）. Conclusions EUS is an ideal diagnostic modality in distinguishing different layers of the wall of the gastrointestinal tract, and thus of important value in precise localization of lesions beneath the mucosa. And be able to hint the nature of the lesion.Meanwhile, this may be associated with colonic mucous membrane structure.
