Abstract
BACKGROUND The majority of benign and malignant lesions of the breast are thought to arise from the epithelium of the terminal duct-lobular unit (TDLU). Although modern mammography, ultrasound, and MRI have improved diagnosis, a final pathological diagnosis currently relies on percutaneous methods of sampling breast lesions. The advantage of mammary ductoscopy (MD) is that it is possible to gain direct access to the ductal system via the nipple. Direct visualization of the duct epithelium allows the operator to precisely locate intraductal lesions, enabling accurate tissue sampling and providing guidance to the surgeon during excision. The intraductal approach may also have a role in screening individuals who are at high risk of breast cancer. Finally, in spontaneous nipple discharge (SND), as biopsy instruments improve and intraductal therapeutics, such as intraductal excision and laser ablation, become a possibility, normal or benign ductoscopic findings may help minimize surgery in selected patients. As MD technology is rapidly advancing, a comprehensive review of current practice will be a valuable guide for clinicians involved in the management of breast disease. METHODS This is a review of current ductoscopic practice based on an exhaustive literature search of Pubmed, Google Scholar, and conference proceedings. The search terms "ductoscopy", "duct endoscopy", "mammary", "breast," and "intraductal" were used. RESULTS/CONCLUSIONS Duct endoscopes have become smaller in diameter with working channels and improved optical definition. Currently, the role of MD is best defined in the management of SND facilitating targeted surgical excision, potentially avoiding unnecessary surgery, and limiting the extent of surgical resection for benign disease. The role of MD in breast-cancer screening and breast conservation surgery has yet to be fully defined. Few prospective randomized trials exist in the literature, and these would be crucial to validate current opinion, not only in the benign setting but also in breast oncologic surgery.

Abstract
PURPOSE To assess the putative predictors that may influence the pain experienced during ductal endoscopy of the breast. METHODS The pain experienced was evaluated in 19 consecutive premenopausal women with bloody nipple discharge scheduled for ductal endoscopy. The visual analog scale (VAS) was used to estimate the degree of pain. The duration of the procedure, the history of lactation, and the phase of the menstrual cycle were evaluated with respect to pain experienced. Statistical analysis followed. RESULTS The average reported pain (VAS score, mean +/- standard deviation) was 5.79 +/- 1.51 while the maximum pain was 8.26 +/- 0.99. The average reported pain was marginally associated with the duration of the procedure in contrast to the maximum. Women who were at the luteal phase of their menstrual cycle exhibited a higher average reported pain. The history of breastfeeding was not associated with the average reported pain, but it was associated with less intense maximum pain. CONCLUSIONS Pain during ductal endoscopy of the breast is influenced by a host of factors: some immutable (such as history of lactation) and others variable (day of menstrual cycle). The latter (ie, avoidance of the luteal phase) may be targeted for the minimization of pain.

Abstract
PURPOSE Ductal endoscopy is valuable for the differential diagnosis of bloody nipple discharge; however, the pain associated with this procedure has not been evaluated. This study aims to assess the pain experienced by patients during ductal endoscopy. METHODS We studied a consecutive series of women who underwent ductal endoscopy, to investigate the cause of bloody nipple discharge. The procedure was performed using standard local anesthesia (lidocaine 1% 10 ml without epinephrine, involving nipple block and periaureolar administration). Patients were asked to score the level of pain with a visual analog scale, 1, 4, 7, 12, 17, 22, 27, and 32 min after the procedure, and describe their overall and maximum pain. RESULTS This series comprised 20 women aged from 27 to 68 years old. The overall pain (mean +/- SE) score was equal to 5.8 +/-0.3, and the maximum pain score was 8.3 +/- 0.2. The peak of pain corresponded with when the dilator was inserted through the sphincter. The group in which the dilator was inserted after 4 min experienced more intense maximum and overall pain after 7, 12, 17 and 22 min. CONCLUSIONS Pain is an important factor in ductal endoscopy, and peaks relatively early. A standard, baseline local lidocaine dose of greater than 10 ml may be necessary at the beginning of the procedure. Late insertion of the dilator seems to be an indicator of the force of the procedure.

Abstract
Minimally invasive surgery is gaining popularity around the world because it achieves the same or even superior results when compared to standard surgery but with less morbidity. Minimally invasive breast surgery is a broad concept encompassing new developments in the field of breast surgery that work on this minimally invasive principle. In this regard, breast-conserving surgery and sentinel lymph node biopsy are good illustrations of this concept. There are three major areas of progress in the minimally invasive management of breast disease. First, percutaneous excisional devices are now available that can replace the surgical excision of breast mass lesions. Second, various ablative treatments are capable of destroying breast cancers in situ instead of surgical excision. Third, mammary ductoscopy provides a new approach to the investigation of mammary duct pathology. Clinical experience and potential applications of these new technologies are reviewed.

Abstract
Mammary ductoscope allows visualization of the breast ductal wall and sampling of the abnormal area for diagnostic purposes. We are reporting our center experience in application of mammary ductoscope in detecting the underlying etiology of pathologic nipple discharge. Between November 2005 and December 2006 a total of 54 women, with spontaneous persistent nonlactational unilateral uniductal nipple discharge of no palpable lesions and negative breast sono-mammography, were included in the study for morphologic assessment of ductal epithelium, ductal lavage and ductoscopically guided procedures as punch biopsy and ductoscopically guided microdochectomy. Forty-one patients (76%) with nipple discharge were positive ductoscopically. Thirteen patients (24%) appeared normal. Ductoscopic lavage has a much more cellular yield than ordinary squeezing cytology. Ductal thickening by the ductoscope (11 cases) revealed to be hyperplasia on pathology (five cases), papilloma (two cases), atypical ductal hyperplasia (two cases), ductal carcinoma in situ (one case), and invasive breast carcinoma (one case). There was a significant association between intraductal visual observations and histopathologic diagnosis. Mammary Ductoscope is a promising tool in management of pathologic nipple discharge. Biopsy and ablation techniques can be performed during ductoscopy with correlation between visual findings and histopathology, but there are still some limitations of in clinical practice.

Abstract
BACKGROUND Mammary ductoscopy (MD) is a newly developed endoscopic technique that allows direct visualisation of the mammary ductal epithelium using sub-millimetre fiberoptic microendoscopes inserted through the ductal opening onto the nipple surface. These scopes also provide working channels for insufflation, irrigation, ductal lavage, and possible therapeutic intervention. MD can be performed under local anaesthesia in the office setting. The objective of this study is to assess the technical feasibility of mammary ductoscopy, and examine its role in guiding ductal excision surgery and the early diagnosis of malignancy. METHODS Mammary ductoscopy (MD) was performed using a 1 mm fiberoptic microendoscope (Mastascope TM) in 26 patients (age range: 14-73 years): 13 patients undergoing mastectomy (n = 12) or lumpectomy (n = 1) for ductal carcinoma (including 12 cases of DCIS and one case of infiltrating ductal carcinoma) and 13 patients with pathological nipple discharge (PND) and benign breast imaging and simple discharge cytology. Of the latter group: 10 procedures were performed under local anaesthesia (LA) in the office setting and 3 procedures were carried out under general anaesthesia (GA) to guide duct excision surgery. The ductoscopic appearances in this group were graded between 0 and 5 (D0-D5) according to the degree of suspicion. RESULTS Intraoperative MD was accomplished in 11 (84.6%) of 13 patients undergoing surgery for DCIS. MD was unsuccessful in 2 cases: one patient (aged 73 years) had sclerosis of the nipple and one patient had preoperative vital blue injection in the subareolar region as part of the sentinel node biopsy thus resulting in inadequate visualisation. Intraductal pathology was visualised in 8 (80%) of the 10 cases undergoing mastectomy but ductoscopic cytology was positive for malignancy in only 2 cases (sensitivity = 16%, specificity = 100%). In the office setting, MD was accomplished in 9 (90%) out of 10 patients with PND and was well tolerated (mean pain score = 3.8 out of 10: range 0-7). Of these 10 patients; MD was inadequate (D0) in one patient due to complete occlusion of lumen by the lesion, showed a papilloma in 3 patients (D3), duct ectasia (D2) in 3 patients, irregular thickening of the lumen suspicious of DCIS (D4) in one patient and non-specific benign findings (D2) in 2 patients. Three women with benign ductoscopy and ductoscopy-assisted cytology were reassured and treated conservatively. The remaining 7 patients had ductoscopy-guided duct excision which revealed DCIS in one, papilloma in 4 and benign breast disease in 2 patients. Adequate cellular yield was obtained in 7 (70%) out of 10 cases (benign cytology). The three patients who had MD under GA during microdochectomy had benign endoscopic appearances and final histology (one papilloma and 2 cases of duct ectasia). CONCLUSION MD is technically feasible in most patients and has a potential in the early detection of breast cancer. The procedure can be performed safely in the office setting and should be considered in all patients presenting with a single duct PND. MD has the potential to reduce the number of duct excision procedures and minimise the extent of surgical resection. Ductoscopic cytology is not sufficiently sensitive for the diagnosis of malignancy and the development of a biopsy tool that obtains tissue under direct visualisation is required.

Abstract
BACKGROUND Fiberoptic ductoscopy is increasingly used to evaluate pathologic nipple discharge. A major limitation of this technique is the inability to obtain tissue samples from suspicious intraductal lesions. We present a novel technique for ductoscopic biopsy of intraluminal tumors. METHODS From 2002 to 2005 ductoscopy was performed in 38 women with nipple discharge using a rigid gradient index microendoscope (diameter 0.7 mm) and a special needle for intraductal vacuum assisted biopsy. Results of preoperative biopsy were correlated with the histology of the resection specimen RESULTS Cannulation of the discharging duct was successful in 37 of 38 patients (97%). Intraductal lesions were diagnosed in 29 women (78%). The sensitivity of ductoscopy and galactography in the detection of intraductal lesion was comparable (96% vs. 89%). Ductoscopic biopsy of intraductal lesions was technically successful in all but one case. Generally, the quality of the biopsy samples was good. Diagnostic biopsy samples were obtained in 26 of 28 patients (93%). Two samples contained necrosis and were considered to be non-representative. Histological analysis of the biopsy specimens showed 22 papilloma, 2 in situ carcinoma and 2 invasive carcinoma. Histology of the resection specimens confirmed the diagnosis in all cases, but there was one case with additional carcinoma lobulare in situ. CONCLUSIONS Ductoscopic vacuum assisted biopsy is a new technique for tissue sampling of intraductal breast lesions. This method may improve preoperative evaluation of pathologic nipple discharge in selected patients, but it should not be considered as a method for screening of early breast cancer.

Abstract
Mammary ductoscopy (MD) has been used as a tool to evaluate the breast for cancer for over 10 years. MD allows the direct visualization of the duct lumen, providing a more targeted approach to the diagnosis of disease arising in the ductal system, since the lesion can be visualized and samples collected in the area of interest. Initial studies of MD evaluated women with pathologic spontaneous nipple discharge (PND), while more recent reports are also using MD to assess women without PND for the presence of breast cancer. Cytologic assessment of MD is highly specific but less sensitive in the detection of breast cancer. Nonetheless, a MD sample from a breast with PND may rarely undergo cytologic review and be interpreted as consistent with malignancy, only later to undergo surgical resection demonstrating benign pathology. For this reason, PND specimens interpreted as malignant on cytologic review require histopathologic confirmation prior to instituting therapy. Additional sample evaluation using image or molecular analysis may improve the sensitivity and specificity of MD in breast cancer detection.

Abstract
BACKGROUND Mammary ductoscopy (MD) is a newly developed endoscopic technique that allows direct visualization and biopsy examination of the mammary ductal epithelium where most cancers originate. The procedure can be performed under local anesthesia in the office setting. This article reviews the rationale, current clinical applications, and limitations of MD. METHODS A literature search was performed using Pubmed for indexed articles published over the past 30 years using the key words "mammary ductoscopy," "breast ductoscopy," "ductal lavage," and "nipple aspiration." The most important articles were analyzed and discussed. RESULTS MD is a useful diagnostic adjunct in patients with pathologic nipple discharge. Furthermore, it can reduce the number and extent of duct excision surgeries for pathologic nipple discharge. There is a clear need to design prospective clinical trials that evaluate the potential role of MD in breast cancer screening, guiding risk-reducing strategies, and as an adjunct to breast-conservation surgery. CONCLUSIONS MD is useful in the management of PND, but its potential role in the early detection or management of breast cancer requires further investigation.

Abstract
Breast papilloma is a term that describes an intraductal papillary configuration of the mammary epithelium on macroscopic or microscopic examination. It includes solitary intraductal papillomas, multiple papillomas, papillomatosis, and juvenile papillomatosis (JP). Recent advances in mammary ductoscopy (MD) have raised new possibilities in the diagnosis and treatment of breast papillomas. This technique represents an important diagnostic adjunct in patients with pathological nipple discharge (PND) by allowing direct visualisation and biopsy of intraductal lesions and guiding duct excision surgery. Treatment of breast papillomas often entails surgical duct excision for symptomatic relief and histopathological examination. Recently, more conservative approach has been adapted. MD-assisted microdochectomy should be considered the procedure of choice for a papilloma-related single duct discharge. Furthermore, there is increasing evidence that MD has the potential to reduce the number of duct excision procedures and minimise the extent of surgical resection. Imaging-guided vacuum-assisted core biopsy can be diagnostic and therapeutic for papillomas seen on mammography and/or ultrasound. Patients with multiple papillomas do have an increased risk of developing cancer and should be kept under annual review with regular mammography (preferably digital mammography) if treated conservatively. Magnetic resonance (MR) can be also used in surveillance in view of its high sensitivity. Because the risk is small, long term and affects both breasts, long-term follow-up is more appropriate than prophylactic mastectomy. Patients who prove to have solitary duct papilloma have insufficient increase in the risk of subsequent malignancy to justify routine follow-up.

Abstract
The intraductal approach to breast cancer and premalignant lesions has now developed to yield substantial cytologic samples of exfoliated cells. Standard cytology is still inadequate in sensitivity and specificity to accurately interpret the majority of samples. As techniques evolve using ductoscopic biopsy and molecular marker panels to increase accuracy of cytologic interpretation, these tools will be able to unravel the breast carcinogenesis pathways. They will also offer considerable benefit in screening for premalignant changes and developing effective chemoprevention strategies.
