Insights
Ductography for nipple discharge is not a reliable substitute for surgery. While it can help identify multiple or peripheral lesions, it may miss or falsely identify intraductal pathology.
Area of Science:
- Breast imaging
- Surgical pathology
Background:
- Nipple discharge management relies on clinical history to differentiate physiologic from pathologic causes.
- The role of ductography in surgical decision-making for nipple discharge requires further investigation.
Purpose of the Study:
- To evaluate the additional information provided by ductography in managing nipple discharge.
- To assess ductography's utility in surgical planning and lesion localization.
Main Methods:
- Retrospective review of 91 patients with nipple discharge from January 1995 to June 1996.
- Analysis of medical records, pathology reports, and ductogram findings.
Main Results:
- 49 patients had physiologic discharge, 42 had pathologic discharge.
- Ductography in 11 patients with physiologic discharge showed no abnormalities.
- Preoperative ductograms in 20 patients revealed intraductal papillomas in 4, with 30% having multiple lesions; 4 lesions were not confirmed surgically.
Conclusions:
- Modern ductography is not a reliable method to exclude intraductal pathology.
- Ductography is not a substitute for surgical intervention in cases of pathologic nipple discharge.
- Ductography's value lies in detecting multiple lesions or peripheral breast lesions.
Background:
Current management of nipple discharge depends on clinical history to distinguish pathologic from physiologic discharge. We investigated whether ductography supplied additional information in the decision for surgery and/or the localization of pathologic lesion.
Methods:
A retrospective review of patients with a presenting complaint of nipple discharge seen at the Lynn Sage Breast Center was conducted from January 1995 to June 1996. Medical records, pathology, and ductograms were reviewed.
Results:
Of 91 patients with nipple discharge, 49 met the criteria for physiologic discharge and 42 had pathologic discharge. Eleven with physiologic discharge had ductograms; none were abnormal. Four of 20 preoperative ductograms were normal but showed intraductal papillomas at the time of surgery; 6 of 20 (30%) had multiple lesions. Four lesions on ductograms did not demonstrate corresponding lesions in the surgical specimen. It is uncertain whether this is due to a missed lesion or a false-positive ductogram.
Conclusions:
Modern ductography does not reliably exclude intraductal pathology and is not a substitute for surgery in patients with pathologic discharge. Its utility is in identifying multiple lesions or those with lesions in the periphery of the breast.
