Combined hysterolaparoscopic surgery usually takes 1-4 hours, but the duration of the procedure fluctuates within a certain range, depending on the specifics of the procedure and the intraoperative situation. If the combined hysteroscopic exploration is only performed without the need for treatment of organic lesions, the surgery can usually be completed in about 1 hour. The surgeon uses hysteroscopy to explore the uterine cavity and laparoscopy to explore the abdominal cavity, and if there is a specific lesion to be treated, the surgery time will be longer. If there are polyps in the uterine cavity or the presence of submucosal fibroids that need to be surgically removed, a hysteroscope will usually be used intraoperatively to find out exactly what is going on in the uterine cavity, and in the case of submucosal fibroids, laparoscopic surgery is usually needed to remove the fibroids. If you are older or have had previous open surgery, this surgery will be more difficult and take longer. The exact duration of hysterolaparoscopic surgery needs to be judged in combination with the type and severity of the disease as well as the difficulty of the surgery. Generally, the operation takes 1-4 hours, and the operation time may be extended if there are difficulties in operation or other interferences during the operation.
