Accuracy of preoperative diagnostic tools and outcome of hysteroscopic management of menstrual dysfunction.

Objective: To review diagnoses, complications, and surgical findings in women treated for abnormal uterine bleeding by operative hysteroscopy, and to assess the accuracy of preoperative transvaginal ultrasound (TVS), saline-infusion sonography (SIS), diagnostic hysteroscopy, and endometrial biopsy.

Methods: Retrospective study (Canadian task force classification II-2). Methods: Tertiary care academic medical center. Methods: Three hundred seventy-five women. Intervention. Operative hysteroscopy for abnormal uterine bleeding.

Results: Main indications for hysteroscopy were postmenopausal bleeding (164 patients, 43.7%) and abnormal premenopausal uterine bleeding (211, 56.3%). Main pathology findings were endometrial polyps (172, 45.9%) and submucous myomas (105, 28%). Polyps had histologic abnormalities in 18 patients. Sensitivity of preoperative diagnostic tools for all intrauterine abnormalities and specifically for myomas and polyps was TVS 74% and 39%, SIS 96% and 96%, hysteroscopy 100% and 99%, and Pipelle biopsy 24% and 10%. The complication rate was 1.3%. Postmenopausal women felt significantly more improvement in symptoms (p = 0.02), and were more satisfied (p

Conclusions: Operative hysteroscopy is a safe outpatient procedure and is associated with high satisfaction in carefully selected patients. Hysteroscopy and SIS are better diagnostic tests for intracavitary abnormalities than TVS and endometrial biopsy.
