Early Gastric Cancer Clinical Trial
Official title:
The Accuracy of Probe-based Confocal Endomicroscopy Versus Conventional Biopsies for the Diagnosis of Superficial Gastric Neoplasias
Confocal endomicroscopy (CLE) allows real-time in-vivo high-resolution and high-magnification imaging of the gastrointestinal epithelium, which is comparable to histopathology. Previous studies have investigated the accuracy of pCLE for diagnosis and differentiated of colorectal polyps, Barrett's esophagus and pancreaticobiliary strictures. However, to date there are limited data exploring the application of pCLE to gastric lesions, and this is the first study comparing the diagnosis of conventional forceps biopsy with that of pCLE using the final specimens obtained from endoscopic resection as a reference standard. The aims of this study were (1) the accuracy of pCLE compared to conventional forceps biopsy using histopathology results following endoscopic resection as a reference, and (2) comparison of "real time" in-vivo pCLE diagnosis with that of blinded "off-line" pCLE diagnosis, and off-line interobserver agreement.
