OBJECTIVE: To compare vaginoscopic hysteroscopic sterilization with traditional hysteroscopic approach for differences in pain, bilateral microinsert placement rates, and procedure time. STUDY DESIGN: We performed a prospective, randomized, single-blinded study of hysteroscopic sterilization using the Essure System. The study setting was an inner city ObGyn clinic. Ninety patients were randomized to either vaginoscopy or traditional approach. The traditional approach was speculum insertion, paracervical analgesia, and tenaculum. All procedures were done with a 5 mm, 30 degree rigid hysteroscope. Main outcome measures were pain scores (10-point visual analog scale), bilateral placement rates, and procedure times. RESULTS: Vaginoscopy was successful in 42/45 patients (93%). There was no statistically significant difference in pain-scores for microinsert placement between the groups (p = 0.71). First attempt, bilateral microinsert placement rate was 95% (40/42) with vaginoscopy and 95% (43/45) with traditional (p = 0.89). Time for treatment completion was 16 minutes (mean) (range, 13-21) in the traditional group versus vaginoscopy time of 9 minutes (mean) (range, 7-11) (p = 0.03). CONCLUSION: Hysteroscopic sterilization via vaginoscopy is feasible with bilateral microinsert rates comparable to those of traditional hysteroscopy. Vaginoscopy is associated with less overall discomfort and is faster to perform.
