ASGE 2023 Masterclass EUS: Principles, Best Practices & Innovative Paradigms (On-Demand)

Video Transcription

Video Summary

In this video, the speaker discusses the use of diagnostic endoscopic ultrasound (EUS) and provides some general tips for using this technique. They emphasize the importance of knowing the equipment, including understanding the spatial relationship of the scanning range to the anatomy, and utilizing features such as gain and frequency to adjust brightness and resolution. The speaker also highlights the importance of knowing the layers of the gastrointestinal tract for diagnosing submucosal lesions. They discuss different types of submucosal lesions, including gastrointestinal stromal tumors (GISTs), lipomas, carcinoids, and duplication cysts, and provide examples of how they can be identified using EUS. They also discuss the challenges of diagnosing chronic pancreatitis using EUS and suggest that it is a complex diagnosis that requires a combination of clinical criteria. The speaker concludes by discussing the role of EUS in diagnosing choledocholithiasis (gallstones in the common bile duct) and suggests that EUS can be useful in patients with intermediate risk factors. They caution against using EUS as a fishing expedition and emphasize the importance of having a clear question in mind when utilizing this technique.
