RESUMEN
Objective To investigate the value of color Doppler ultrasonography in mammary ductal ectasia( MDE). Methods Preoperative sonograms of 54 MDE,135 invasive ductal carcinoma( IDC) and 68 ductal carcinoma in situ ( DCIS ) patients were retrospectively analyzed and further confirmed by histopathology. Results MDE showed 88.9% (48/54) mass type and 11.1% (6/54) ductal type.The average age of patients in MDE was younger than that in IDC( P ＜0.05). The number of MDE located around the areola was more than that of IDC( P ＜0.05). Mean maximum diameter of MDE was smaller than that of DCIS ( P ＜0.05). Compared to DCIS and IDC,MDE in mass type showed higher detection rate of liquidity area and mammary ductal ectasia( all P ＜0.05),while lower detection rate of hyperecho, peripheral hyperechoic zone,posterior echo attenuation or blood flow richness( all P ＜0.001). Compared to IDC,MDE in mass type showed higher detection rate of inside ductal echolocation,while showed lower detection rate of irregular shape,spiculate margin or axillary lymph node enlargement. Compared to DCIS, MDE showed higher detection rate of large aspect ratios( ≥0.7). Less MDE in ductal type with hyperecho were found than DCIS in ductal type ( P ＜ 0.001 ). The coincidence rate of ultrasonic diagnosis and postoperative histopathhology results in 54 MDE patientis was 13.0% ( 7/54 ). Conclusions The sonographic findings of MDE has diverse manifestations. It shows important value of ultrasonography for MDE in its diagnosis and differential diagnosis with breast cancer.
RESUMEN
Objective To evaluate the clinical value of fiberoptic ductoscopy in diagnosis and treatment of patients with galactophoritis or mammary duct ectasia. Methods From November 2005 to March 2008, fiberoptic ductoscopy were performed in 120 women with nipple discharge. The duct of 95 cases as non-malignant lesion were insufflated and perfusioned with entamycin and dexamethasone. Results Ninty-five of 120 cases were non-malignant disease,which contained one side 81 and two sides 14; the discharge was bloody,ivory, stramineous in 21, 17, 57 patinents, respectively; and the dignosis were 17 mammary duct ectasia, 53 galactophoritis, and 25 mammary duct ectasia with galactophoritis. Of the 95 cases, hich were intradutal insufflated and perfusioned with gentamycin and dexamethasone, the nipple discharge were decreased or disappeared in 81 cases, the effective rate was 85.3%. Conclusion Fiberoptic ductoscopy is a convenient,safe, accurate method in diagnosis and treatment of patients with galactophoritis or mammary duct ectasia.
