During laparoscopic surgery, only 2~3 small puncture holes of 0.5~1.0 cm in diameter are made in the abdominal wall, and microscopic instruments are placed to perform surgical operations. Compared with traditional open surgery, it is less traumatic, less bleeding, less painful, faster postoperative recovery and shorter hospital stay, fully reflecting the modern humanistic concept of curing diseases with less trauma and cost, which is the direction of modern gynecological surgery development. Diseases suitable for laparoscopic treatment: 1. tubal lesions – such as ectopic pregnancy, tubal effusion, adhesions, tubal sterilization and recanalization, etc.; 2. ovarian cysts – such as “chocolate” cysts, simple cysts, teratomas, polycystic ovaries, etc.; 3. intermyometrial, broad ligament and subplasma 4. pelvic endometriosis and myometriosis; 5. infertility due to tubal and uterine factors; 6. structural disorders of the pelvic floor – uterine prolapse, etc.; 7. pelvic inflammatory disease, pelvic abscesses, adhesions, chronic pelvic pain, etc.; 8. cervical intraepithelial neoplasia and cervical carcinoma in situ; 9. ectopic intrauterine device, uterine perforation; 10. Total hysterectomy can be performed under laparoscopy for lesions requiring uterine removal.
