What is the most effective method of permanent tubal sterilization?

The most effective method of permanent tubal sterilization is partial salpingectomy. This technique involves the surgical removal of a portion of the fallopian tubes, creating a barrier that prevents sperm from reaching the egg, thereby significantly reducing the likelihood of fertilization. The removal of a segment of the tube is an effective means of preventing ectopic pregnancies as well and is associated with lower failure rates compared to other sterilization methods.

Partial salpingectomy offers advantages beyond simply occluding the tubes, including a potentially lower risk of menstrual irregularities compared to techniques that do not involve resection. In addition, it has gained popularity due to its effectiveness and the increasing evidence supporting its role in reducing long-term risks associated with tubal ligation, such as the possibility of tubal regeneration.

While other methods like interval tubal occlusion, hysteroscopic sterilization, and the Pomeroy method also serve the purpose of sterilization, they may not provide the same level of efficacy or risk reduction as seen with partial salpingectomy.
