Scraping for endometrial thickening usually takes about 10-20 minutes, depending on the patient’s endometrial condition and the surgeon’s surgical proficiency, the exact procedure time may vary. If the endometrium is thickened and accompanied by abnormal vaginal bleeding, patients are often advised to undergo hysteroscopy and diagnostic scraping. On the one hand, the diagnosis can be clarified and endometrial tissue can be obtained for pathological examination; on the other hand, appropriate treatment can be performed, for example, in patients with endometrial polyps, surgery can be performed at the same time. The operation of surgical clearance usually takes 10-20 minutes and may be prolonged if the patient has other comorbidities. Patients with endometrial thickening should maintain a light diet, take appropriate supplements of meat, eggs and milk, strengthen physical exercise, and seek timely medical attention to cooperate with the doctor’s treatment.
