The role of endobronchial ultrasound in the diagnosis and staging of gastrointestinal malignancies

In addition to the critical role of endoscopic ultrasound in gastrointestinal malignancies, endobronchial ultrasound (EBUS) may compliment the evaluation and treatment of esophageal and nonesophageal malignancies. Using both convex and radial probe ultrasound, the mediastinum and parenchymal lung lesions may be evaluated to more precisely determine the extent of disease compared with traditional strategies. EBUS may also provide therapeutic advantages by assisting in stent placement or treating parenchymal metastases. This article aims to discuss the benefits derived from using EBUS in the diagnosis, staging, and treatment of gastrointestinal malignancies.
