Tubal ligation : ウィキペディア英語版 | Tubal ligation
Tubal ligation or tubectomy (also known as having one's "tubes tied" (ligation)) is a surgical procedure for sterilization in which a woman's fallopian tubes are clamped and blocked, or severed and sealed, either method of which prevents eggs from reaching the uterus for implantation. However, fertilization can still occur in the fallopian tubes. Tubal ligation is considered a permanent method of sterilization and birth control. ==Procedure== Tubal ligation (incorrectly referred to as tubectomy) is considered major surgery requiring the patient to undergo spinal anesthesia. It is advised that women should not undergo this surgery if they currently have or had a history of bladder cancer. After the anesthesia takes effect, a surgeon will make a small incision at each side of, but just below the navel in order to gain access to each of the two fallopian tubes. With traditional tubal ligation, the surgeon severs the tubes, and then ties (ligates) them off thereby preventing the travel of eggs to the uterus. Other methods include using clips or rings to clamp them shut, or severing and cauterizing them. Tubal ligation is usually done in a hospital operating-room setting.
