This manual, edited by Sushma Deshmukh and Osama Shawki, was created to fill an information gap: its structure, of a predominantly practical nature, aims to facilitate the learning of some diagnostic and surgical hysteroscopy techniques, and to provide an update on the most recent applications of the branch. The basic requirements and equipment for carrying out an outpatient hysteroscopy are analyzed (Chapters 1, 2, 3 and 4), the pathologies that can be addressed with the hysteroscopic technique are investigated, from the most frequent to the most innovative ones (Chapters 5–17), and suggested measures for preventing complications, using simple practical tips (Chapters 18 and 19). Overall, this update manual will satisfy those who want practical answers to everyday questions, without having to spend excessive time delving into each individual topic.
