Are there clinically important risks associated with hysteroscopic sterilization compared with laparoscopic sterilization?
In this cohort study of 105 357 women who underwent a first sterilization, the use of hysteroscopic sterilization was significantly associated with lower immediate risk of procedural complications than laparoscopic sterilization (0.13% vs 0.78% for surgical complications and 0.06% vs 0.11% for medical complications); and higher risk of gynecological complications with 4.83% vs 0.69% for sterilization failure and 5.65% vs 1.76% for gynecological reoperation over 1 year; these differences persisted over 3 years, although attenuated. Risk of medical outcomes was not significantly increased over 1 year or over 3 years.
These findings do not support an increased risk of medical outcomes related to hysteroscopic sterilization.
Safety of hysteroscopic sterilization has been recently questioned following reports of general symptoms such as allergy, tiredness, and depression in addition to associated gynecological results such as pelvic pain, perforation of fallopian tubes or uterus, and unwanted pregnancy.

Design, Setting, and Participants
French nationwide cohort study using the national hospital discharge database linked to the health insurance claims database. Women aged 30 to 54 years receiving a first hysteroscopic or laparoscopic sterilization between 2010 and 2014 were included and were followed up through December 2015.
Hysteroscopic sterilization vs laparoscopic sterilization.
Main Outcomes and Measures
Risks of procedural complications (surgical and medical) and of gynecological (sterilization failure that includes salpingectomy, second sterilization procedure, or pregnancy; pregnancy; reoperation) and medical outcomes (all types of allergy; autoimmune diseases; thyroid disorder; use of analgesics, antimigraines, antidepressants, benzodiazepines; outpatient visits; sickness absence; suicide attempts; death) that occurred within 1 and 3 years after sterilization were compared using inverse probability of treatment–weighted Cox models.
Of the 105 357 women included (95.5% of eligible participants; mean age, 41.3 years [SD, 3.7 years]), 71 303 (67.7% ) underwent hysteroscopic sterilization, and 34 054 (32.3%) underwent laparoscopic sterilization. During the hospitalization for sterilization, risk of surgical complications for hysteroscopic sterilization was lower: 0.13% for hysteroscopic sterilization vs 0.78% for laparoscopic sterilization (adjusted risk difference [RD], −0.64; 95% CI, −0.67 to −0.60) and was lower for medical complications: 0.06% vs 0.11% (adjusted RD, −0.05; 95% CI, −0.08 to −0.01). During the first year after sterilization, 4.83% of women who underwent hysteroscopic sterilization had a higher risk of sterilization failure than the 0.69% who underwent laparoscopic sterilization (adjusted hazard ratio [HR], 7.11; 95% CI, 5.92 to 8.54; adjusted RD, 4.23 per 100 person-years; 95% CI, 3.40 to 5.22). Additionally, 5.65% of women who underwent hysteroscopic sterilization required gynecological reoperation vs 1.76% of women who underwent laparoscopic sterilization (adjusted HR, 3.26; 95% CI, 2.90 to 3.67; adjusted RD, 4.63 per 100 person-years; 95% CI, 3.38 to 4.75); these differences persisted after 3 years, although attenuated. Hysteroscopic sterilization was associated with a lower risk of pregnancy within the first year of the procedure but was not significantly associated with a difference in risk of pregnancy by the third year (adjusted HR, 1.04; 95% CI, 0.83-1.30; adjusted RD, 0.01 per 100 person-years; 95% CI, −0.04 to 0.07). Risks of medical outcomes were not significantly increased with hysteroscopic sterilization compared with laparoscopic sterilization.
Conclusions and Relevance
Among women undergoing first sterilization, the use of hysteroscopic sterilization was significantly associated with higher risk of gynecological complications over 1 year and over 3 years than was laparoscopic sterilization. Risk of medical outcomes was not significantly increased over 1 year or over 3 years. These findings do not support increased medical risks associated with hysteroscopic sterilization.
