Historical perspective on procedures to ligate the fallopian tube for sterilization
Author(s): Thomas P. Ryan

Paper Abstract

After decades of attempts to occlude the fallopian tube thorough mechanical, cautery, and chemical techniques, no practical solution has yet attained wide clinical success and usage. An historical tour of prior techniques such as caustic chemicals, polymer injections, implants, and mechanical or thermal techniques is provided herein. Promising contemporary methods employ heat as a technique for lesioning the fallopian tube, although the original work in thermal treatment dates back to 1878. Recent studies performed in animal models employ microwave or radiofrequency devices that have the potential to succeed as transcervical solutions, accomplishing tubal ligation without surgery. In cases where an implant is used instead of energy delivery to thermally ablate, the natural peristalsis of the fallopian tube causes these implants to migrate and become expelled. Failure equates to unwanted pregnancy or ectopic pregnancy, a pregnancy outside of the uterus. Thermal techniques have the advantage of leaving no foreign body behind and can be carefully monitored and controlled in both the temperature and time domains. The energy sources include conductive sources, laser, cryogenic, microwave and radiofrequency devices. The most promising studies utilize thermal methods with the temperature monitored and well regulated. This will assure consistent, circumferential lesion formation, occlusion of the tube through fibrosis, and clinical success.
