Endoscopic diagnosis of lateral spreading tumours (LST) with submucosal invasion is important in guiding the treatment strategy. The use of advanced imaging is not standard clinical practice in China. A clinical trial is now under way comparing the accuracy of narrow band imaging (NBI), endoscopic ultrasonography (EUS) and magnifying chromoendoscopy (MCE) for the diagnosis of LST with submucosal invasion.

By comparing the consistency of histologic diagnosis and preoperative evaluation,the diagnostic accuracies of various endoscopic examination techniques(narrow band imaging , endoscopic ultrasonography , and magnifying chromoendoscopy) was calculated respectively.
