背景：内窥镜乳头切除术是治疗十二指肠乳头肿瘤的一种安全可靠的方法。对于完全切除，目的：我们的目的是通过比较窄带成像(NBI)和靛红(IC)染色内窥镜，前瞻性地评估十二指肠乳头肿瘤侧缘增强治疗EP的效果。设计：前瞻性研究。背景：该手术是在东京医科大学医院进行的。患者：连续14例主要十二指肠乳头肿瘤。干预：所有患者在NBI和IC评估后行EP。主要结果测量：通过与块组织的比较，对NBI和IC诊断的组织学评价。结果：在所有病变中，除I-IC外，IC和NBI均优于常规白光成像。NBI观察对强调肿瘤边缘的能力明显优于IC观察(P
Background: Endoscopic papillectomy (EP) has been recognized as a safe and reliable treatment for tumor of the duodenal papilla. For complete resection, precise assessment of not only the intraductal extent but also the lateral margins of the tumor is mandatory before resection.Objective: Our purpose was to prospectively assess the enhancement of the lateral margins Of tumor of the duodenal papilla for the treatment of EP by comparing narrow-band imaging (NBI) and indigo carmine (IC) chromoendoscopyDesign: Prospective study.Setting: This procedure was performed in Tokyo Medical University Hospital.Patients: Fourteen consecutive cases of tumors of the major duodenal papilla.Intervention: All patients Underwent EP after evaluation by NBI and IC.Main Outcome Measurement: Histologic evaluation of diagnosis of NBI and IC by comparison with ell bloc tissue.Results: In all lesions, either IC or NBI were superior to conventional white-light imaging except in I IC case. The ability of NBI observation to emphasize the tumor margin was statistically significantly better than IC observation (P
