[Microdochectomy with perioperative dye localization of ducts in patients with nipple secretion].

A series of 1321 women having a discharge from the nipple were examined at the outpatient clinic. Of seven basic types of discharge: milky, multicolored, purulent, watery, yellow (serous), serosanguineous and bloody, only the last four represent and indication for surgery. Galactography was performed in 55 patients as a necessary element in the surgical plan of management. In 36 women, the operation of microdochectomy was indicated, but only 24 accepted to be subjected to that procedure. The authors describe a new technique of colour mammary ductal localization which identifies the duct from which the discharge is emerging and assures its complete excision. The procedure combines preoperative methylen blue dye injection followed by periareolar incision of the involved duct using a pair of binocular loops for magnification of the nipple. In all tissue specimens, the cause of a pathological discharge was found: 15 (62.5%) cases presented with fibrocystic disease, and in 6 carcinoma was present. This technique provides a safe and effective method of complete excision of the pathologically involved mammary duct with good cosmetic results.
