When the endometrial thickening is not bleeding, hysteroscopy can usually be performed on an outpatient basis or hospitalized for hysteroscopy, and the decision should be based on the individual’s condition. In case of endometrial thickening, if the examination is simple and does not require special treatment and there is no excessive bleeding, it can be performed directly in the outpatient clinic. However, if there are infections in the uterine cavity, uterine polyps, etc., the examination will be accompanied by treatment, and if the examination is performed in the outpatient clinic, it will not be conducive to the post-operative care, and the doctor will ask the patient to be hospitalized. In case of endometrial thickening, it is recommended to go to the hospital in time and choose between outpatient and inpatient hysteroscopy under the guidance of the doctor.
