Endoscopy Live: GERD & Barrett's Esophagus: The Journey Continues

Video Transcription

Video Summary

In this video, John, a gastroenterologist at Stanford, gives a presentation on manometry and pH impedance studies. He starts by explaining how these studies are performed and then proceeds to walk through several live cases to demonstrate the interpretation of the results. In the first case, a 58-year-old woman with globus is being evaluated using manometry and pH impedance. John explains the different components of the study, including the integrated relaxation pressure (IRP), amplitude of contraction, and distal contractile integral. He discusses normal ranges and how to interpret abnormalities related to outflow obstruction or achalasia. John also highlights the use of provocative maneuvers, such as multiple rapid swallows, and the potential of impedance studies to assess fluid flow and guide treatment decisions. In subsequent cases, John discusses the findings of a patient with a hiatal hernia, a patient with GERD and dysphagia, and a patient with jackhammer esophagus. He concludes by emphasizing the importance of accurately diagnosing and treating these motility disorders based on the specific findings observed in the studies. The video is a part of an educational lecture and does not provide information on any credits.
