A new study led by researchers at Weill Cornell Medicine found that non-incision surgery, uteroscopic sterilization, is as effective as minimally invasive laparoscopic sterilization, either method. The failure rate was higher than expected.

Comparative study published on April 12 Fertility and infertility, The failure rate of both methods was found to be 5-6% 5 years after the procedure. Dr. Irene Galiepee conducted an investigation while at Yale School of Medicine. She is currently the director of complex family planning at Weill Cornell Medicine’s Obstetrics and Gynecology Department. Her collaborators included Dr. Eleanor Bimura Schwartz of the University of California, San Francisco and the University of California, Davis, and Dr. Diana Zuckerman of the National Center for Health Research.

“The rate we found is Sterilization The 1% failure rate that doctors often quote when counseling patients. ” She said the 1% figure is based on data decades ago from a joint US sterility review study.

At 219 million woman And their partners rely on women’s sterilization surgery, which is considered a permanent way to prevent pregnancy, and is the most commonly used contraceptive method in the world. In the United States, sterilization is more commonly used by women insured by Medicaid than by women with private health insurance, according to researchers.

The purpose of this study was to compare the effectiveness of hysteroscopic and laparoscopic sterility procedures. For laparoscopic sterility, the surgeon can make a small incision near the navel and use a variety of methods to cut or close the fallopian tubes.

Uterine sterility Medical equipment Known by the trade name of Essure, which blocks the fallopian tubes.Embedded metal coil produces Scar tissue Prevents pregnancy over time.

The US Food and Drug Administration (FDA) first approved Essure in 2002, and researchers reported zero cumulative pregnancy rates from two studies that followed 197 women in Essure over a two-year period.

With increasing oversight from the FDA and increasing questions about device effectiveness and safety, manufacturers have opted to withdraw Essure from the market in 2019 because of lower sales. However, the question remained for the woman who had not experienced the problem and had not removed the device.

“Women and doctors want to know:’Can I rely on this to prevent pregnancy?'” Said Dr. Galiepee.

Keeping in mind that hysteroscopic sterilization is becoming more and more common among Medicade insured women, including patient stakeholders, researchers from several academic institutions, and community partners across the country. , Dr. Galiepy and her collaborators examined Medicade’s claims for hysteroscopic and laparoscopic sterilization in California. Between 2008 and 2014. They ruled out postpartum sterilization surgery performed using different approaches.

“In a previous study, sterilization surgery for women with commercial insurance, Health outcomes It’s often different from someone who has Medicaid, “Dr. Galiepee said. “It was important to see the experience of those who have Medicaid and their actual results.”

Using Medicaid data, researchers identified 5,906 women who underwent hysteroscopy and 23,965 women who underwent laparoscopic sterilization. The average age was 33 years.

“Five years after surgery, the cumulative rate of pregnancy was over 6%, regardless of whether the woman had undergone hysteroscopy or laparoscopic sterilization,” the researchers write.

“Women need to know the true risk of failure,” said Dr. Galiepee, who said the findings show that, for example, further research is needed to determine whether a particular surgical technique has contributed more than expected. Added. Pregnancy rate..
