Endometrial and endocervical brushing techniques with a Medhosa cannula.
A new technique for obtaining endometrial material using the Medhosa Cannula is described. This method is also useful to obtain samples from the endocervix. The Medhosa Cannula is made of flexible plastic. It is 30 cm long and has thin fins on its distal end which, guided by an introduction cone, permit endometrial and endocervical brushing. Six hundred cases are reported. Concomitant histopathological studies were performed in 40 per cent of the patients. There were two false negative cytologic reports (0.88%) and one false positive (6.66%). This is a simple, rapid, innocuous and economical technique, thus fulfilling the prerequisites for routine cytodiagnostic methods. Adequate material was always obtained.
