AIM: To assess sensitivity and specificity of Karman aspiration in the diagnosis of abnormal endometrium compared with the final diagnosis and evaluate tissue adequacy obtained by Karman aspiration. METHODS: The study group were women who presented with abnormal uterine bleeding to Songklanagarind Hospital between August 2003 and July 2004 and who underwent Karman aspiration prior to conventional curettage. The final diagnosis was defined as the most severe histopathology from either Karman aspiration or conventional curettage. Abnormal endometrium included inflammation, polyp, hyperplasia and malignant changes. RESULTS: Two hundred and twenty-six women were assessed. Endometrial aspiration showed a sensitivity of 89.6% and specificity 100.0% in diagnosis of abnormal endometrium. Abnormal endometrium was detected in 58 women. Of 11 women diagnosed with endometrial cancer, only one case was undetected by Karman aspiration due to a failure to create negative pressure in the uterus. Endometrial aspiration yielded adequate tissue in 86.7%. CONCLUSION: Karman endometrial aspiration is an accurate and easy procedure, and should be considered in the initial evaluation of abnormal uterine bleeding.
