哈萨克族早期食管癌及癌前病变的内镜分析

目的 探讨窄带成像放大内镜对哈萨克族早期食管癌及癌前病变患者的诊断价值.方法 选取2014年1月~2016年7月在我院行常规内镜检查诊断为食管黏膜病变的哈萨克族患者106例为实验组研究对象,随机选取30例同时期在我院进行健康体检者(常规内镜检查食道黏膜未见异常)作为对照组.分别应用窄带成像放大内镜观察两组患者的食管上皮乳头内毛细血管袢(IPCL)的形态学改变,统计其分型结果.同时对实验组行病理学检查,统计其病理诊断结果.结果 实验组病理诊断结果:早期食管癌10例,低级别瘤变16例,高级别瘤变11例,食管炎69例;IPCL分型结果:对照组均为Ⅰ型;实验组中早期食管癌的IPCL分型主要为Ⅳ型,低级别瘤变主要为Ⅱ型与Ⅲ型,高级别瘤变主要为Ⅲ型,食管炎分型主要为Ⅱ型.结论 窄带成像放大内镜可清晰的显示食管病变位置及病变范围,并能通过食管黏膜IPCL分型来分析组织学的病理类型,对诊断哈萨克族早期食管癌及癌前病变具有较高的临床价值.

Endoscopic analysis of early esophageal cancer and precancerous lesions in Kazakh patients

Objective To explore the value of endoscopic narrow-band imaging in the diagnosis of early-stage esophageal cancer and precancerous lesions in Kazakh patients. Methods A total of 106 Kazakh patients with esophageal mucosa lesions diagnosed by routine endoscopy in our hospital from January 2014 to July 2016 were enrolled in this analysis with 30 randomly selected patients with normal endoscopic findings of the esophageal mucosa as the control group. The morphological changes of papillary capillary loop (IPCL) of the esophageal epithelium in the two groups were observed by narrow-band imaging magnifying endoscopy.Pathological examinations were performed for all the patients with esophageal mucosa lesions. Results In patients with esophageal mucosa lesions, 10 were diagnosed to have early esophageal cancer, 16 had low-grade tumors,11 had high-grade tumors and 69 had esophagitis.IPCL typing results showed IPCL type I in all the control subjects,predominantly type IV in patients with early esophageal carcinoma,type II and III in patients with low-grade tumor,type III in patients with high-grade tumor,and type II in patients with esophagitis.Conclusion The location and size of the esophageal lesions can be observed clearly by narrow-band imaging magnifying endoscopy. The histopathology of the esophageal mucosa can be analyzed with IPCL classification for diagnosis of early esophageal cancer and precancerous lesions in Kazakhs.
