[Endometrial aspiration biopsy].
The factuality and diagnostic accuracy of aspiration endometrial biopsy with Karman's cannula, as compared with the curetted sample with Novak's cannula, were evaluated. Two hundred and thirty endometrial biopsies, were taken, as part of the study in women with fertility problems, at the Assisted Reproduction Clinic and Sterility Clinic, Instituto Nacional de Perinatología. The samples taken with Karman's cannula, Group I (n = 115); and with Novak's cannula, Group II (n = 115), were compared: procedure's time, pain intensity, quantity and quality of samples, macro and microscopically. In 92.2% of group I, tissue adequate for diagnosis, was obtained, as compared with 84.4% in Group II; likewise, the sample was better quantitatively and qualitatively, in Group I; and required time was less than one minute in 90% in Group I, an 83% in Group II. With the use of Karman's cannula, 20% of the patients had no pain, and 0.9% with the use of Novak's cannula. So, it can be concluded that endometrial aspiration with Karman's is reasonable and reliable in the functional histological diagnosis; it permits the obtention of adequate samples, in quantity and quality, and offering as advantages less pain and more security for the patients.
