Post procedural pregnancy occurrence risk after endometrial ablation.

Area of Science:

• Gynecology
• Reproductive Medicine
• Surgical Innovation

Background:

• Abnormal uterine bleeding (AUB) affects many women, often treated with procedures like curettage, endometrial resection (1G), and endometrial ablation (2G).
• Understanding post-procedural pregnancy rates is crucial for patient counseling and management.

Purpose of the Study:

• To compare pregnancy rates following curettage, 1G endometrial resection, and 2G endometrial ablation in women with AUB.
• To enhance pre- and post-therapeutic information for women undergoing these procedures.

Main Methods:

• Retrospective analysis of French hospital data (2009-2015) for women diagnosed with AUB and undergoing surgical procedures.
• Inclusion of 109,884 women, with follow-up periods up to 60 months.
• Comparison of pregnancy rates (primary endpoint) between 2G procedures, 1G procedures, and curettage.

Main Results:

• Pregnancy rates were 1.5% after 2G, 10.1% after 1G, and 11.1% after curettage.
• A significant difference in pregnancy rates was observed between 2G procedures and both 1G procedures and curettage (p<0.0001).
• No significant age difference was noted between the groups.

Conclusions:

• Second-generation endometrial ablation procedures are associated with a lower risk of pregnancy compared to first-generation procedures and curettage.
• Endometrial ablation should not be considered a method of sterilization or effective contraception.
• Continued contraception is recommended for all women, regardless of age or menstrual status, unless sterilization has been performed.
