Cesarean section refers to a surgical procedure where the abdominal wall is incised to enter the abdominal cavity, and then the uterus is cut open to deliver the fetus. Since the abdominal cavity is entered, the fallopian tubes can be seen. During a cesarean section, if there are special circumstances, tubal ligation can be done incidentally. For example, if a woman has a serious heart disease or has experienced multiple pregnancies with placenta accreta, these conditions strictly prohibit her from getting pregnant in the future. In such cases, tubal ligation can be performed simultaneously with the cesarean section to achieve sterilization. However, for ordinary women, it is generally not recommended to undergo ligation during a cesarean section because ligation may cause harm to a woman's body, leading to adhesions or affecting ovarian function. Moreover, there are many other methods in clinical practice that can achieve contraceptive or sterilization effects. Therefore, whether to perform ligation during a cesarean section should be determined on an individual basis.
