Endoscopic ultrasound (EUS)-guided Trucut biopsy adds significant information to EUS-guided fine-needle aspiration in selected patients: A prospective study

Abstract

EUS-TCB was certainly useful when immunohistochemistry was needed, for example in submucosal tumours and lymphoma, as well as to confirm and characterize the primary or metastatic origin of mediastinal masses. The information provided by EUS-FNA and EUS-TCB is complementary, especially in selected cases where a complete histological diagnosis has an important impact on the clinical management.
