You are the gynaecology registrar in the ambulatory clinic. A 42-year-old woman with a 9-month history of heavy menstrual bleeding, a normal cervical screening history, a body mass index of 28, and a transvaginal ultrasound showing a 22 mm endometrial polyp and a normal myometrium is referred by her GP for hysteroscopy. The examiner will ask you to take a focused history, plan the workup, consent her, choose the right setting, and defend your plan — including what to do if you find a submucous fibroid, a perforation, or a rising fluid deficit.
