Ductoscopy Coupled to Duct Lavage and Duct Brushing in Pathologic Nipple Discharge: Our Experience

to present our experience in the management of pathological nipple discharge using the procedure D.DL.DB: "ductoscopy" (D) coupled to "duct lavage" (DL) plus "duct brushing" (DB) for etiologic diagnosis. Also to compare the diagnosis obtained with D.DL.DB to the final histology.

Eighty-five patients with organic unilateral nipple discharge were enrolled in two Breast Units. 82 of 85 patients were investigated successfully with D.DL.DB. Results:: The final histological results were: papilloma 46.3%, duct ectasia 36.5%, breast cancer 8.5%, precancer lesions 4.9%, and mixed benign lesions 3.8%. Pyramidectomy and radical ductectomy were performed in 76 and 6 cases respectively. In 80% of the cases, DLDB cytology results were identical to the final histology. (Kappa=0;69 CI=[0.56 -0.82]. The sensitivity of D.DL.DB versus pathology, for cancer or precancer lesions was 81.8% (CI=0.59 -1) and the specificity was 97.1% (CI=0.93 -1). Using Koch scale, the concordance between the two methods D.DL.DB and surgery was high and the sensitivity was in the upper range regarding the literature (58% to 90%).

Our experience confirms the high value of D.DL.DB in the management of organic nipple discharge.
