Abstract

Objective To compare the diagnostic accuracy of magnifying chromoendoscopy (MCE) and endoscopic ultrasonography (EUS) for preoperative endoscopic assessment of the invasion depth of colorectal laterally spreading tumour(LST). Methods Data of 104 cases of colorectal LST were included. With the final pathological diagnosis as the golden standard, the accuracies of MCE and EUS for preoperative assessment of the invasion depth of colorectal LST were compared. Results The diagnostic accuracies of MCE and EUS for evaluating the invasion depth of LST were 89.4%(93/104) and 73.1%(76/104), respectively(P<0.05). The lesion size and the endoscopist could affect the accuracy of the EUS evaluation(P=0.017, OR=3.561; P=0.035, OR=1.399). The accuracy of EUS seemed to show a downward trend for colorectal LST of larger diameters. Conclusion Both MCE and EUS are effective for evaluating the invasion depth of colorectal LST, but the accuracy of MCE may be higher than that of EUS. Large diameter of the lesion and the doctor's experience inadequacy may be the risk factors for the accuracy of EUS. Key words: Colorectal neoplasms; Endosonography; Program evaluation; Laterally spreading tumor; Magnifying chromoendoscopy

术前内镜评估结肠横向扩散肿瘤侵袭深度的临床研究

目的比较放大彩色内窥镜（MCE）和内镜超声（EUS）在术前内镜评估结肠横向扩散肿瘤（LST）侵袭深度中的诊断准确性。方法收集104例结直肠LST患者的临床资料。以最终病理诊断为金标准，比较MCE和EUS术前评估结直肠LST侵袭深度的准确性。结果MCE和EUS对LST浸润深度的诊断准确率分别为89.4%（93/104）和73.1%（76/104）（P<0.05）。病变大小和内镜医生可能影响EUS评估的准确性（P=0.017，OR=3.561；P=0.035，OR=1.399）。EUS对大直径结肠直肠LST的准确性似乎呈下降趋势。结论MCE和EUS均能有效评价结直肠癌LST的侵袭深度，但MCE的准确性可能高于EUS。病变直径大和医生经验不足可能是影响EUS准确性的危险因素。关键词：结直肠肿瘤；腔内超声；项目评估；横向扩散肿瘤；放大彩色内窥镜检查

期刊介绍： Chinese Journal of Digestive Endoscopy is a high-level medical academic journal specializing in digestive endoscopy, which was renamed Chinese Journal of Digestive Endoscopy in August 1996 from Endoscopy. Chinese Journal of Digestive Endoscopy mainly reports the leading scientific research results of esophagoscopy, gastroscopy, duodenoscopy, choledochoscopy, laparoscopy, colorectoscopy, small enteroscopy, sigmoidoscopy, etc. and the progress of their equipments and technologies at home and abroad, as well as the clinical diagnosis and treatment experience. The main columns are: treatises, abstracts of treatises, clinical reports, technical exchanges, special case reports and endoscopic complications. The target readers are digestive system diseases and digestive endoscopy workers who are engaged in medical treatment, teaching and scientific research. Chinese Journal of Digestive Endoscopy has been indexed by ISTIC, PKU, CSAD, WPRIM.
