Hysteroscopy, and especially office-based hysteroscopy, is a fantastic tool in the evaluation of suspected endometrial abnormalities and/or heavy menstrual bleeding. In this session, we will review the ACOG committee opinion on hysteroscopy. At what fluid deficit should you stop the procedure if using normal saline? What about glycine? What is the significance of a “mill-wheel” murmur. Do you know what the Durant maneuver is? We answer all of these questions and more in this session!
