Preventing re-adhesion after hysterolaparoscopic surgery can be done through postoperative intrauterine device (IUD), intrauterine balloon placement and other methods. 1. Intrauterine sterilization ring: It can keep the uterine cavity separate and prevent the uterine cavity from re-adhesion. If there is a requirement for childbearing, the IUD can be removed three months later, 3-7 days after menstruation; if there is no requirement for childbearing, the time of removal can be decided according to the type of IUD inserted and its expiration date. 2. Intrauterine balloon: A balloon can be placed in the uterine cavity after the operation and removed after one week to prevent adhesion again, and anti-inflammatory drugs can be taken during this period to prevent the occurrence of infection. Uterine adhesion is a complication of transuterine operation. If adhesion is found by hysteroscopy or ultrasonography, adhesion detachment should be carried out in time and anti-adhesion treatment should be given in the postoperative period.
