Hysteroscopic Sterilization Device Follow-Up Rate: Hysterosalpingogram Versus Transvaginal Ultrasound
Bibliographic record
Abstract
Abstract Study Objective To assess if follow-up confirmation testing 3 months after hysteroscopic sterilization with the Essure device (Bayer HealthCare Pharmaceuticals, Inc., Whippany, NJ) improved with recommendation for transvaginal ultrasound (TVUS) versus hysterosalpingogram (HSG). Design Retrospective, observational case-controlled cohort study (Canadian Task Force classification II-2). Setting Two-physician private practice in Evansville, Indiana. Patients Compliance rates for a TVUS confirmation test on 100 women who underwent hysteroscopic sterilization compared with a previously published cohort of 1004 women who were scheduled to undergo an HSG confirmation test. Intervention Acquisition of 3-month confirmation testing after Essure hysteroscopic sterilization. Measurement and Main Results All women who underwent Essure hysteroscopic sterilization with recommendation for TVUS confirmation testing between July 2015 and January 2017 were compared with a previously published cohort of 1004 patients with recommendation for HSG confirmation testing (HSG cohort). In addition, an HSG subgroup cohort (HSG subgroup) similar in size and closest chronology to the TVUS cohort was drawn from the original 1004 patients and analyzed for HSG follow-up. Records for all patients were reviewed for demographic, procedural, and confirmation testing and outcome data. One hundred patients were identified with successful Essure device placement and a recommendation for TVUS confirmation testing. Eighty-eight patients (88.0%) returned for TVUS at 3 months. In the HSG cohort 1004 successful Essure devices were placed, and 778 patients returned for the recommended HSG follow-up (77.5%). There was a significantly higher follow-up rate for TVUS compared with the HSG cohort (88.0% vs 77.5%, p = .008). In the HSG subgroup 184 patients were identified, and 133 patients presented for HSG follow-up (72.3%), indicating a significantly higher follow-up rate in the TVUS cohort (88.0% vs 72.3%, p = .001). No pregnancies after any confirmation testing were noted. Conclusion Confirmation testing with TVUS rather than HSG 3 months after Essure device placement results in increased patient compliance that may lead to improved patient outcomes with reduction of unintended pregnancy.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
