Outpatient diagnostic hysteroscopy.

STUDY OBJECTIVE: To evaluate the feasibility, validity, indications, and results of a large series of diagnostic hysteroscopies performed without anesthesia. DESIGN: Retrospective analysis of hysteroscopy charts performed between 1989 and 1996 (Canadian Task Force classification II-2). SETTING: University-affiliated endoscopy unit. PATIENTS: Four thousand consecutive women referred for different indications. INTERVENTIONS: Diagnostic hysteroscopy was performed in 91% of patients without premedication or anesthetics. In some women premedication or general or local anesthesia was required to access the uterine cavity. MEASUREMENTS AND MAIN RESULTS: The success rate, validity indication, complication rate, and number of biopsies were critically evaluated and assessed in relation to increased experience of operators. In 91% of women we accessed the uterine cavity at the first attempt without premedication, whereas 207 (5. 1%) patients required local anesthesia and 99 (2.4%) premedication. Only 1.6% required general anesthesia. In 52% intrauterine pathology was diagnosed and in 21% further surgical treatment was suggested. CONCLUSION: Hysteroscopy was feasible when performed in an outpatient setting without general or local anesthesia in more than 90% of women. The operator's experience seems a key factor both for accurate endometrial evaluation and to reduce failure and endometrial biopsy rates. The low frequency of further surgical treatment justifies performing the procedure in the office.
