Improving ductoscopy with duct lavage and duct brushing

Aim: To assess the combined technique of duct lavage (DL) and duct brushing (DB) performed during ductoscopy in pathological nipple discharge (PND). Materials and Methods: The study was conducted in two hospitals: Rea (Greece) and in Meet Ghmmr Oncology Center (Egypt), from January 2011 to April 2013. Sixty-four women were enrolled. A sample of cells was collected with the use of DB. Afterwards, DL was performed. For each case, liquid cytology was compared to the final histology. Results: From the 19 histological diagnosis of duct ectasia, cytology by DL plus DB (CDLDB) was correct in 17 cases (89.5%). For 28 papillomas, CDLDB was correct in 19 eases (67.9%). For breast cancer (six cases), CDLDB was correct in five cases (83.3%). Also, CDLDB found 45.5% of miscellaneous benign cases. In total, cytology performed by CDLDB was correct in 46 of 64 patients: 71.9%. Thus, the sensitivity of CDLDB ranged from 67% to 90%, depending on the histological diagnosis. Conclusion: This technique showed a high accuracy, in contrast to other studies that used only DL.
