摘要:
目的   探讨高频超声内镜鉴别上消化道黏膜内癌及黏膜下癌的价值。   方法   129例上消化道早期癌患者术前行高频超声内镜检查,分析上皮内癌、黏膜肌层癌、黏膜下癌的超声影像学特征。34例行内镜下黏膜切除术,5例行内镜下黏膜下剥离术,90例行外科手术。术后标本行病理学检查确定其浸润深度。   结果   高频超声内镜显示上皮内癌30例,黏膜上皮层增厚,黏膜肌层形态规则;黏膜肌层癌42例,36例黏膜层及黏膜肌层增厚,两层界限不清楚,黏膜下层形态规则,6例黏膜层及黏膜肌层增厚,黏膜下层部分稍增厚,形态规则;黏膜下癌57例,黏膜下层形态改变,变细8例,增粗6例,扭曲5例,不规则10例,部分中断12例,与黏膜肌层分界不清楚16例,固有肌层形态规则。术后病理:黏膜内癌78例,黏膜下癌51例。高频超声内镜判断黏膜内癌特异性为92.2%(47/51),敏感性为87.2%(68/78),黏膜下癌特异性为87.2%(68/78),敏感性为92.2%(47/51),其鉴别黏膜内癌及黏膜下癌准确性为89.1%(115/129)。   结论   高频超声内镜能较准确鉴别上消化道黏膜内癌及黏膜下癌。
Abstract:
Objective   To explore the value of ultrasonic endoscopy in discriminating intramucosal carcinoma from submucosal carcinoma in the upper gastrointestinal tract.   Methods   Preoperative ultrasonic endoscopy was performed in 129 cases with early cancers of the upper gastrointestinal tract. The ultrasonographic images of intraepithelial carcinoma, muscularis mucosae carcinoma, and submucosal carcinoma were analyzed. Endoscopic mucosal resection, endoscopic submucosal dissection, and surgical operation were performed in 34, 5, and 90 cases, respectively. The infiltration depth of early cancers was confirmed pathologically after operation.   Results   Ultrasonic endoscopy revealed intraepithelial carcinoma in 30 cases with thickened mucosa epithelial lamina and regular morphology of muscularis mucosae, muscularis mucosae carcinoma in 36 cases with thickened mucosa and muscularis mucosae unclear demarcation but regular morphology of submucosa, muscularis mucosae carcinoma in 6 cases with partially thickened submucosa but regular morphology, submucosal carcinoma in 57 cases with changed submucosal morphology (thinned in 8 cases, thickened in 6 cases, twisted in 5 cases, irregular in 10 cases partially discontinued in 12 cases, and unclear of muscularis mucosae and submucosa ambit in 16 cases). Pathological examination after treatment reported 78 cases of intramucosal carcinoma and 51 cases of submucosal carcinoma. The specificity and sensibility in intramucosal carcinoma by ultrasonic endoscopy were 92.2% (47/51) and 87.2% (68/78) while in submucosal carcinoma were 87.2% (68/78) and 92.2% (47/51). The diagnostic accuracy in differentiating intramucosal carcinoma from submucosal carcinoma by ultrasonic endoscopy was 89.1% (115/129).   Conclusion   Ultrasonic endoscopy is effective in differentiating intramucosal carcinoma from submucosal carcinoma in the upper gastrointestinal tract.
