Abstract:
Objective To evaluate the clinical value of breast localization needle placed via mammary ductoscopy in surgical treatment of patients with intraductal neoplasms. Methods In this study,76 patients with intraductal neoplasms diagnosized by mammary ductoscopy from January 2009 to March 2010 in the Second Affiliated Hospital of Soochow University were randomly divided into two groups.For methylene blue group,ducts with the lesion were marked by methylene blue injection before operation.For localization needle group,ducts were marked by localization needle placed via ductoscopy.The operative time,specimen weight,incision length and diagnostic coincidence rate were compared among the two groups. Results Compared to the methylene blue group,the localization needle group had a significantly shorter operative time (31 ± 8 min vs.42 ± 9 min),lighter specimen weight (1.51 ± 1.36 g vs.2.95 ± 2.07 g),and shorter incision (23.2 ± 7.8 mm vs.34.4 ± 7.1 mm).All the breast cancer cases dianosised by mammary ductoscopy were confirmed by postoperative pathology,but the localization needle group had a higher diagnostic coincidence rate than the methylene blue group (94.7% vs. 76.3%). Conclusion Localization needle under mammary ductoscopy is a reliable technique for localizing intraductal neolasms.The surgical excision guided by localization needle is accurate and less traumatic,and should be a routine method marking the tumor involved duct before operation.
