Study Compares Risks Between Methods of Sterilization

Bottom Line: Hysteroscopic sterilization, a non-surgical procedure that involves placing small implants in the fallopian tubes to make a woman infertile, was associated with an increased risk of gynecological complications (most notably sterilization failure with subsequent pregnancy) compared to surgical sterilization, but there were no differences between the two approaches in medical outcomes.

Why The Research Is Interesting: In developed countries, two main types of female sterilization are available: hysteroscopic and laparoscopic, the latter involving general anesthesia and a small incision in the abdominal wall. Safety concerns related to hysteroscopic sterilization were raised in the United States in 2015 by women who reported to the U.S. Food and Drug Administration (FDA) large numbers of adverse events, including bleeding, unwanted pregnancy, abdominal pain, depression, and thyroid disorders.

Who and When: 105,357 women in France who underwent hysteroscopic sterilization or laparoscopic sterilization between 2010-2014 and followed up through December 2015.

What (Study Measures): Hysteroscopic sterilization or laparoscopic sterilization (exposures); risks of procedural complications (surgical and medical), gynecological complications (sterilization failure that includes second sterilization procedure or pregnancy) and medical outcomes (including all types of allergy; autoimmune diseases; thyroid disorder; use of analgesics, antimigraines, antidepressants, outpatient visits; sickness absence; suicide attempts; death) that occurred within one and three years after sterilization (outcomes)

How (Study Design): This is an observational study. Because researchers are not intervening for purposes of the study they cannot control natural differences that could explain the study findings.

Results: Hysteroscopic sterilization was associated with a lower immediate risk of procedural complications and a higher risk of gynecological complications, but not associated with an increased risk of certain medical outcomes.

Study Limitations: Administrative databases were used to investigate a possible role of hysteroscopic sterilization in notified complaints. All individual disorders reported by patients or physicians and collected into medical device vigilance databases could not be examined.

Study Conclusions:
Meaning: These findings do not support an increased risk of medical outcomes related to hysteroscopic sterilization.
