Trial Identification
Brief Title: Biopsy Protocol of Upper Gastrointestinal Subepithelial Tumors:Diagnostic Accuracy of EUS-FNB Versus Unroofing Biopsy
Official Title:
Study ID: NCT02646241
Study Description
Brief Summary: To increase the diagnostic accuracy of subepithelial tumors, larger tissue samples are required. It is difficult to obtain adequate tissue samples. There were several biopsy methods to obtain tissue samples. Pathological examination would include mitosis counts, particularly in hypoechoic subepithelial tumors located in the 4th layer of the gastric wall, where differentiation between leiomyoma of benign nature and gastrointestinal stromal tumor (GIST) of malignant potential is essential. So We hypothesize that unroofing biopsy is an more appropriate method than EUS-FNB(endoscopic ultrasonography guided fine needle biopsy). We will compare diagnostic accuracy and complications between EUS-FNB \& unroofing biopsy.
