Title: Clinicians explore ways to improve sterilization efficacy. Journal: Contracept Technol Update; 1987 Jun; 8(6):1-5. PubMed ID: 12268496. Abstract: The US Centers for Disease Control (CDC) have begun a large-scale epidemiologic study to explore failure rates and outcomes of all currently used tubal sterilization methods. The CDC plans to recruit 12,000 newly sterilized women and follow them for 5 years. Results of the study may not be published until follow-up is complete in 1992. This study should answer questions about which methods have the highest failure rates and whether failures for each method are more likely to result in intrauterine or ectopic pregnancies. Until these data area in, it is best to rely on expert anecdotal reports. Jaroslav Hulka, developer of the Hulka clip, has kept careful watch over the successes and failures of his device. The clip works better when placed correctly across the isthmic portion of the Fallopian tube rather than across the ampulla of the tube. Inbae Yoon presented an improved technic for the application of his Falope ring last year. Richard Soderstrom and Barbara Levy have been examining failures in bipolar coagulation and have discovered that clinicians who mismatch bipolar forceps and electric generators are very likely setting themselves up for sterilization failure. 3 charactersitics of women who are predisposed to sterilization technical failure are 1) recent use of an IUD, 2) history or current evidence of a pelvic inflammatory disease, and 3) a history of spontaneous abortion. These factors all relate to infection. There are some occlusion technics that put a premium on tubal maneuverability, such as the Falope ring. Pelvic adhesions or thichened tubes can interfere with the maneuverability of the tubes and make the procedure very difficult to perform.[Abstract] [Full Text] [Related] [New Search]
