[Progress of ductoscopy of the breast].
Ductoscopy of the breast was initially performed utilizing a rigid scope. Improvements in endoscopic equipment and introduction of the silica-fiberscope have enabled observation of intraductal lesions. The silica-fiberscope can be gradually moved into peripheral sites, after which the endoscopic findings are compared with histological features and diagnostic imaging. The most common symptom dictating endoscopic examination is a discharge from the nipple in which no palpable mass is detected. The fiberscope is introduced through the duct orifice on the surface of the nipple. The characteristic feature of a cancerous lesion is a superficial spread along the surface of the ductal lumen, which differs from the typical features of intraductal papilloma. Microsampling methods such as tube curette cytology should be used to obtain a definitive diagnosis. Endoscopic examination can provide valuable information which will be helpful in the decision process such as; surgical methods, nipple-preservation, and breast conservation.
