Endoscopic ultrasound in the staging of gastrointestinal luminal malignancies

Endoscopic ultrasound (EUS) is an important tool in the staging of gastrointestinal cancers. This review highlights the use of EUS in the staging of gastrointestinal luminal malignancies and compares the performance of EUS with other imaging modalities (CT, MRI and PET-CT) in the staging of these malignancies. Management algorithms in the staging of these malignancies are also presented.
