Usually there is a water passage after the reversal surgery, which has to be performed by a specialized doctor. Reopening surgery refers to tubal anastomosis, and flushing refers to tubal ligation. Tubal anastomosis is the process of removing the tubes that have been ligated or blocked and reconnecting the two broken ends to restore patency. However, because the surgery can cause inflammatory reactions in the fallopian tubes, postoperative tubal ligation is needed to understand the effect of unblocking, and can also play a role in certain re-blocking. After the tubal ligation surgery, we should pay attention to appropriate rest, appropriate increase in diet and nutrition to promote physical recovery, keep the vulva clean and dry, follow the doctor’s advice to give metronidazole, cefuroxime sodium and other antibiotics to prevent infections, prohibit tub baths and sexual life for 1 month. After the operation, you should follow the doctor’s instruction to perform 1~2 times of tubal lubrication when the menstruation is clean for 3~7 days, and then prepare for pregnancy under the doctor’s guidance.
