EFFICACY OF AN ORIGINALLY DEVICED CYTOLOGY BRUSH IN THE DIAGNOSES OF PANCREAS CANCER

Abstract

Recently in diagnosing of pancreatic cancer, endoscopical pancreatic biopsy and brushing cytology have been performed. We developed an originally deviced cytology brush which has 2.4 mm in diameter and 220cm in effective length allows to insert into the cannula for peroral micropancreatoscopy. This brushing can be carried out through the cannula after peroral micropancreatoscopy. We compared the rate of positive diagnosis of pancreatic cancer in 15 patients for the endoscopical pancreatic biopsy (43%), the ordinary cytology brush (60%) and our cytology brush (80%). It is suggested that our cytology brush is very useful for the diagnosis of pancreatic cancer.
