Mammary Ductoscopy Visualizes Breast Tissue.
DANA POINT, CALIF. -- Mammary ductoscopy is on its way to becoming a practical tool for visualizing abnormalities in breast tissue, obtaining tissue samples, and directing surgeons to the precise location of abnormal tissue,
The investigational technique has been tested in women with abnormal nipple discharge and is being studied in women undergoing lumpectomy. In the future, modifications that reduce the cost of the procedure may well make ductoscopy useful as a screening method in women at high risk for breast cancer, Dr. Jill Dietz said at a science writers seminar sponsored by the American Cancer Society
Dr. Dietz of the Cleveland Clinic Foundation uses a ductoscope manufactured by Acueity Inc., a Larkspur, Calif., maker of microendoscopic systems. Dr. Dietz also receives research funding from Acueity.
The device is 1.2 mm in diameter and can penetrate up to 8 cm into the breast. The ductoscope, which includes a light source and a camera, can accommodate a 200-[micro]m-diameter channel, which is used to inject air or saline solution or to withdraw tissue samples.
Dr. Dietz has used the device in women with a runny, bloody, or serous discharge that typically came out of a single orifice in the nipple. The ductoscope is inserted through the discharging orifice and threaded through the ductal system in order to visualize the precise location of the abnormality. The scope is then used to direct surgery After the abnormal tissue has been removed, Dr. Dietz uses the ductoscope to ensure that the rest of the duct looks normal.
Dr. Dietz uses ductoscopy routinely in women presenting with pathologic nipple discharge. But, she noted, just ...
