ASGE 2023 Masterclass EUS: Principles, Best Practices & Innovative Paradigms (On-Demand) | February 2023-EUS Cancer Staging Case-based Presentation

Video Transcription

Video Summary

In this video, Dr. Vivek Kaul and Dr. Nuzhat Ahmad discuss the role of endoscopic ultrasound (EUS) in the diagnosis and staging of various gastrointestinal (GI) neoplasms. They highlight the importance of EUS in primary mucosal staging of upper GI neoplasms, stating that radial EUS makes it easier to delineate these lesions compared to linear EUS. They also emphasize that EUS has no role in cancer staging with metastatic disease unless tissue from a lymph node is required for some other reason. Tangential imaging techniques are discussed to avoid misinterpretation of T3 lesions. The doctors mention the use of EUS in rectal ultrasound for rectal cancer staging, as well as its role in assessing sphincter muscles and determining the need for transanal or minimally invasive surgery. EUS is also considered helpful in identifying lymph nodes for biopsy in various malignancies. The video concludes with a discussion on the role of EUS in esophageal, gastric, ampullary, pancreatic, and rectal cancers, and its complementary nature to other imaging modalities such as CT and MRI.
