ABSTRACT
Endoscopic brush cytology is a valuable technique for the evaluation of biliary strictures. The sensitivity of this technique varies from 30% to 83%, however, it can have specificity of 100%. We retrospectively evaluated the usefulness of wire-guided biliary brush cytology in biliary strictures in our hospital over a 3 years period from 1997 to 2000. Brushings from 58 biliary strictures were obtained during endoscopic retrograde cholangiography. They were compared with histological proof obtained by surgical biopsy or percutaneous fine-needle aspiration cytology and/or clinical findings. These were reported as benign or malignant. Eleven patients were excluded due to incomplete data. Eighteen patients had benign brushings. Fourteen of the 29 patients in whom histological confirmation of malignancy brushings was obtained were also reported as malignant. The sensitivity of endoscopic brushings was 48.2%, specificity 100% and diagnostic accuracy 55.2%. No major complications were seen in our study group.
