RESUMEN
STUDY OBJECTIVE: To determine factors associated with hysteroscopic sterilization success and whether it differs between the operating room and office settings. DESIGN: Retrospective cohort analysis (Canadian Task Force classification II-2). SETTING: Major university medical center. PATIENTS: Six hundred thirty-eight women who underwent hysteroscopic sterilization between July 1, 2005, and June 30, 2011. MEASUREMENTS AND MAIN RESULTS: Data collected included age, body mass index, previous office procedures, previous cesarean section, and presence of myomas or retroverted uterus. Place of surgery, experience of surgeon, insurance type, bilateral device placement, compliance with hysterosalpingography, and confirmation of occlusion were also recorded. Bivariate analysis of patient characteristics between groups was performed using χ(2) and independent t tests, and identified confounders and associated variables. Multivariate analysis was performed using logistic regression to assess for association and to adjust for confounders. Procedures were performed in the operating room (57%) or in the office (43%). There was no association between success in bilateral device placement or occlusion and any patient characteristic, regardless of surgery setting. Private insurance, patient age, and performance of procedures in the office setting were positively associated with likelihood of compliance with hysterosalpingography. CONCLUSION: Successful device placement and tubal occlusion are independent of patient age, body mass index, or setting of the procedure. Association between insurance type and completing hysterosalpingography illustrates an important public health problem. Patients who fail to undergo hysterosalpingography to confirm tubal occlusion may unknowingly be at risk of pregnancy and increased risk of ectopic pregnancy.
