Background: Most patients suffering from pathological nipple discharge (PND) undergo local surgical procedures because standard radiological imaging often fails to reveal the cause. Ductoscopy is a minimally invasive endoscopic technique that enables direct intraductal visualization and can avoid unnecessary diagnostic surgical procedures. Hence, patients with recurrent or persistent PND after an unsuccessful ductoscopy procedure still undergo unnecessary surgery. This study describes the experience of a second ductoscopy procedure in patients with recurrent or persistent PND without suspicious radiological findings. Methods: Patients with recurrent or persistent PND who underwent two ductoscopy procedures between 2010 and 2017 were retrospectively analyzed. The second ductoscopy was performed when the first ductoscopic attempt was unsuccessful due to technical problems. The primary outcome was the number of preventable surgical procedures. Results: A total of 17 patients underwent two ductoscopy procedures. The first ductoscopy showed a polypoid lesion in 10 patients (58.8%), no abnormalities in 3 patients (17.6%), and in 4 patients (23.5%), it was not possible to visualize the ductal tree. Post-procedure, all patients suffered from PND. After two ductoscopic attempts, PND stopped in 10 patients (58.8%), and 7 patients (41.2%) still suffered from PND and were operated on. Pathology of the resection specimens showed no abnormalities in 1 patient, a papilloma in 5 patients, and ductal carcinoma in situ in 1 patient. Conclusion: A second ductoscopy procedure can be considered in the diagnostic work-up of patients suffering from persistent or recurrent PND after an unsuccessful first ductoscopic attempt to avoid unnecessary surgery in about 59% of the cases.
