目的评价IPCL分型在判断早期食管癌及癌前病变浸润深度中的应用价值。方法在白光和窄带成像技术（NBI）模式下观察食管黏膜病变的大小、范围，应用放大胃镜观察病变部位上皮乳头内毛细血管袢（IPCL）形态，采用日本AB分型法进行IPCL分型，判断病变的浸润深度，对符合内镜下切除适应证的早期食管癌及癌前病变行内镜下黏膜下剥离术（ESD）,完整切除病变后标本送病理检查，以病理结果作为金标准，将IPCL分型的结果与术后标本病理结果进行对照。结果共55例食管病变实行内镜下切除，术前IPCL分型判断的病变浸润深度与术后病理符合者共40例，符合率为72.0%。结论IPCL分型在判断早期食管癌及癌前病变浸润深度中符合率较高，操作简便，有较高的临床应用价值。

ObjectiveTo assess the value of intrapapillary capillary loop(IPCL) classification applied to the assessment of early esophagus carcinoma and infiltration depth of precancerous lesions. MethodsThe size and range of esophageal mucosa lesions were observed using white-light endoscopy and narrow band imaging.Magnifying endoscopy was used to observe the IPCL of the lesions, then IPCL classification was performed with Japanese AB classification. And the infiltration depth of the lesions was assessed. Endoscopic submucosal dissection was conducted in cases with the early esophagus carcinoma and precancerous lesions according with the indication of endoscopic resection. Pathological examination was conducted after complete removal of specimens. The pathological result was taken as the golden standard, then IPCL classification was compared with the postoperative pathological result. ResultsEndoscopic resection was performed in 55 esophageal lesions. The infiltration depth of 44 cases assessed by IPCL classification was concordant with the postoperative pathological result, and the coincidence rate was 72.7%. ConclusionIPCL classification can achieve a high coincidence in the assessment of early esophagus carcinoma and infiltration depth of precancerous lesions. This classification is simple and has a high value of clinical application.
