Intrauterine administration of methyl cyanoacrylate as an outpatient method of permanent female sterilization.

Results are presented of multicenter studies on the intrauterine delivery of 0.6 ml methyl cyanoacrylate with the FEMCEPT device (BioNexus Inc., Raleigh, North Carolina) for the purpose of causing permanent obstruction of the fallopian tubes. The studies included 1279 women and were conducted under several different protocols that required either one or two methyl cyanoacrylate application procedures. Based on hysterosalpingograms obtained about 16 weeks after the last methyl cyanoacrylate application, one procedure resulted in a tubal closure rate of 71.4% and two procedures resulted in a tubal closure rate of 89.4%. Complications of the procedure were infrequent and none required surgical treatment. Cumulative pregnancy rates among women with hysterosalpingogram-demonstrated bilateral tubal closure were similar for the one- and two-application procedures that used nonradiopaque methyl cyanoacrylate and were significantly lower (p less than 0.05) compared with a single application of radiopaque methyl cyanoacrylate. The 3-year pregnancy rate for two applications of nonradiopaque methyl cyanoacrylate was 1.7 +/- 1.2 per 100 women.
