Whether or not combined hysterolaparoscopy is necessary needs to be decided according to the patient’s disease, such as both abdominal and uterine cavity diseases are usually necessary. Laparoscopy usually refers to the treatment of diseases of the pelvic and abdominal cavities, such as gallbladder stones, appendicitis, ovarian cysts, etc., with instruments under the direction of the laparoscopic lens, and it can also observe the fallopian tubes and the uterus to see if they are normal in shape. Hysteroscopy is the treatment of diseases of the uterine cavity, such as adhesions in the uterine cavity, endometrial polyps, etc., under the instruction of the hysteroscope lens, and it can also observe the shape of the uterine cavity and the growth of the endometrium. Laparoscopy and hysteroscopy do not target the same areas, and it is usually necessary for patients with both pelvic and abdominal diseases and uterine cavity diseases, such as ovarian cysts combined with endometrial polyps, and especially for infertility patients, who need to observe the uterine cavity and fallopian tube morphology at the same time. However, it is not absolute. For example, gallbladder stones combined with endometrial polyps can be operated with combined hysterolaparoscopy or in two separate operations. Patients who have questions about the procedure can ask the physician responsible for the treatment of their disease.
