Feasibility and Therapeutic Efficacy of Ductoscopic Papilloma Extraction in Patients With Pathologic Nipple Discharge

In this prospective clinical trial, patients who sign an approved informed consent for ductoscopy to assess etiology of Pathologic nipple discharge (PND) will be enrolled in the study. Consented patients who have been diagnosed with a solitary papilloma within the discharging duct will be recruited to have interventional ductoscopy. Patients who are identified ductoscopically with a solitary non-sessile papilloma will undergo an attempted ductoscopic papillectomy (DP). Patients with ductoscopic findings other than single non-sessile papilloma will undergo standard ductoscopically guided microductectomy. The investigators will investigate whether the ductoscopic basket can be used as a safe endoscopic extraction instrument without adverse events. Histopathological evaluation will be performed to confirm the ductoscopic diagnosis and to determine the existence of any malignant tissue.
