Does the method of tubal ligation alter the failure rate?
Yes. The ten-year failure rates of the commonly performed tubal ligations are as follows: • Filshie clip application 1.2 % • Bipolar electrosurgical tubal coagulation 2.48 % • Unipolar electrosurgical tubal coagulation 0.75 % • Silicone/Falope ring 1.77 % • Spring clip (Hulka) 3.65 % • Interval partial salpingectomy 2.01 % • Post-partum partial salpingectomy 0.75 % The overall ten-year failure is 1.85 percent. Many of the late failures result in ectopic pregnancy.
