Ask me anything! HRM and Impedance-pH studies


Tuesday December 19, 2023

14:00 - 14:45 GMT (UK)

15:00 - 15:45 CET (Europe)

Do you have questions about the practical challenges of High Resolution Manometry or Impedance-pH studies? Or do you struggle with the interpretation of the results?

Questions like:

  • How long should we stop medication prior to the study?
  • How can I pass the LES?
  • Are there any differences between the results of body position?
  • Is there any relevance for calculation of the EGJ contractile integral?
  • What is the minimum number of symptoms needed for Impedance-pH studies?
  • If SAP is positive, but SI is negative, can we still say it has good correlation?

Together with Prof. Arjan Bredenoord and RN Jac. Oors from the Amsterdam Medical Center, Laborie organizes a live Q+A session to give you the opportunity to ask your questions directly to the speakers.


Physicians, GI Physiologists, Nurses, Nurse practitioners, Physicians Assistants and other health care professionals.

NO RECORDING: Note that this webinar can only be viewed live as it will not be recorded.
