Histopathologic evaluation of uteri curetted by flexible suction cannula.

A prospective study was undertaken to evaluate the use of the flexible plastic cannula for obtaining endometrial specimens for diagnostic purposes. Suction curettage was performed immediately prehysterectomy, the specimens evaluated, and then compared to similar specimens obtained by a metal curette. Another group of patients had suction curettage performed as an office procedure 24 to 72 hours before hysterectomy. The results of our study confirm the adequacy of this method for obtaining endometrial samples.

Rapid hCG-specific radioimmunoassay for menstrual aspiration.

Fifty-one women with missed periods ranging from 5 to 14 days who suspected a pregnancy underwent an aspiration curettage with a flexible soft-tipped cannula attached to a Karman-type syringe. Sera from these women were measured for human chorionic gonadotropin (hCG) by a rapid 2-hour solid phase radioimmunoassay using an antibody with a specificity for the beta subunit of hCG. The sensitivity and specificity of this assay insured detection of bCG with 100% accuracy at the time of the missed period. Of the 51 women, 33 (64.7%) were found to have hCG in their serum, and 29 (56.8%) had histologic evidence diagnostic of pregnancy.
