Therapeutic value of a new scarless intervention, ductoscopic papillomectomy, in patients with pathologic nipple discharge

Results Ductoscopy was successfully performed in 178 patients. Of these 178 patients, 34 had solitary papillomas (SP), 8 had multiple papillomas (MP), 19 had intraductal debris and 5 had ductal epithelial surface abnormality with positive cytology. Of the 34 polypoid lesions (cytology negative), 22 were excised endoscopically (endoscopic papillomectomy). Patients with MP underwent DAmicrodochectomy. These 42 patients (34 with SP, and 8 with MP) had histopathology results consistent with intraductal papillomas or papillomatosis. Five patients with positive cytology underwent DA-terminal ductal lobular unit excision after their histopathology reports showed had DCIS. Except in one patient, all discharges disappeared. After a mean ± SD follow up time of 14.4 ± 5.2 months (range, 1–27 months), there were no recurrences of nipple discharge and no radiological results suggestive of malignancy. Thus, the therapeutic efficacy of EP in our study was 95.4% (21/22).
