Laparoscopic tubal sterilization. Methods, effectiveness, and sequelae.
The following statements summarize the material presented herein. 1. Although laparoscopic tubal ligation remains an effective and widely available form of birth control throughout the world, cumulative failure rates may be higher than previously reported, and patients should be appropriately counseled, with special attention to younger women. 2. Proper surgical technique is important in reducing failure rates, particularly with regard to applying clips or using bipolar cautery. Teaching institutions should employ strict guidelines for instructing residents in the most effective techniques. 3. Although overall rates of ectopic pregnancy are lower after tubal ligation (as is true with any form of birth control), should pregnancy ensure from a failed procedure, there is a 30% to 80% chance of ectopic pregnancy. Consideration should be given to earlier ultrasound and documentation of the location of the pregnancy. 4. There is little evidence to support PTLS from a biologic standpoint. The data on increased hysterectomies in post-tubal patients may be a result of multiple factors, particularly for women aged less than 30 years at the time of occlusion. 5. Although the majority of women report satisfaction with sterilization, thorough counseling for all women cannot be overemphasized. Women aged less than 30 years should be completely aware of all alternatives and possibly encouraged to try another method prior to permanent sterilization.
