Abstract


Mammary Duct Ectasia(MDE)is a kind of inflammation that is noninfected、nontumorous inflammation.The morbidity reason of it is not very clear up to now.There are some pertinent possible factors with it, congenital nipple deformation or dysplasia、suckling defilade、ductal inadequate drainage or blockage、breast trauma、breast inflammation、ductal degeneration、autoimmunity functional disturbance and so on.The main clinical manifestation includes breast lump、breast pain、nipple discharge、Sagging breasts、adherence of breast Skin.There are some examination methods of MDE,such as high- frequency or color Doppler ultrasound、X-ray photographs、mammography、fiberoptic galacto-endoscope(FDS). They have different diagnostic value and disadvantages to breast ductal disease. According to some Records,high-frequency ultrasound has much higher diagnostic rate to this disease. We found that it had restrict clinical significance for the specific typing of disease、development process of the disease、therapeutic methods,if we merely use high-frequency ultrasound.X-ray photographs is not fit for orient female because of high-density and micromastia. Mammo- graphs of the duct can show us the ectasy mammary ducts very clearly,having some superiority,at the same time ,with some insult and radioaction. It was very popular that fiberoptic ductoscopy were used in examination of breast ductal disease,it has much higher diagnostic rate to breast diseases than ultrasonography and mammography according to some reports. The records that combinates high-frequency ultrasound with fiberoptic ductoscopy in order to analyze and diagnose MDE are quite rare,There are much fewer documents about analysis and diagnosis of MDE according to clinical classification.In this study,above two inspection means are efficiently contrasted and linked,Aiming to evaluate their value in diagnosis of this disease.In this study,we choose 390 cases,which are totally diagnosed as MDE by pathological diagnosis,including lump-type 206 case(s52.82%), nipple discharge-type109 case(s27.95%), mixed-type 75 cases (19.23%). They are examinated by fiberoptic galacto-endoscope and ultrasound, analyzing the internal characteristic of lumens under fiberoptic galacto-endoscope and the appearance of the ultrasound , which enhance the apprehension about the mammary duct ectasia and clinical tying. We can raise the rate of detection and diagnosis by the effective methods.The study shows us :1、Nipple discharge-type effluxs the fluid which is stramineous、serosity and milk-like, Blood-type is less, which may be the only or first symptom, sometimes following with the mastalgia . Most of the cases are simple comedomastitis (66.97%) ,which is more than the lump-type (12.44%)(p<0.05),24.77% of the affection include the main mammary ducts distension and inflammatary change on duct wall. The ultrasound inspection finds that 62.39% of the cases have distended galactophore , some of them are scrotiform and connect with the galactophore, 18.39% of them are normal . The ultrasound has high diagnosis rate for diagnosing the cystic extending duct or the type that capsular is in the deeper location; When ultrasound inspection is normal, fiberoptic galacto-endoscope can examine them very clear.2、The size of lumps in the lump-type are different , the bigger are lamellar thickening ,felt hard ,no limit, and have the pain . The clinical manifestation are accretion and edema of skin , nipple recovery and acute inflammation . The proportion of the comedomastitis combined with galactophoritis is 58.18%, which is more than the proportion of the nipple discharge-type . The proportion of the blunting galactophoritis is 29.53% ,less of them is simple comedomastitis , The proportion of disordering reverberation and parenchymatous reverberation combining with the comeomastitis in the ultrasonic inspection is 62.30 % . part of them have scrotiform distended galactophore . The ultrasound has high diagnostic rate for acute mammary inflammation, but the fiberoptic galacto-endoscope has no much significance and it is not easy to do examination in the acute stage,but aggravates the disease. The glandular tissue feel hard、obscure boundary and the ultrasound find the irregular lamellar low echo,some have dilating catheter ,some don,t. We must identify it with the breast cancer . Combining with the clinic feature of the MDE and breast cancer, if it has the continuous duct wall、dilating ducts and inflammation of duct in the fiberoptic galacto-endoscope, but no excrescent mass ,it is significant for eliminating the breast cancer. So we can make the conclusions:Both fiberoptic galacto-endoscope and ultrasound inspection are based on the pathological changes and process of the disease . Because of the pathological changes of the MDE, it is classified into pathological stage、clinic typing and clinical stage, which make the examination more effective. Both of them have a great significance to the detection and diagnose for different types of the MDE.First : Nipple discharge-type is main in simple mammary duct dilating, Fiberoptic galacto-endoscope is significant for this type, ultrasound has an assistant part in diagnosis; the lump-type show as mainly mammary duct dilating and inflammation, fiberoptic galacto-endoscope and ultrasound inspection can be combined for diagnosis,sometimes for treatment, then it will have great clinical significance.Seond : When the mammary duct dilates to be cystic or acute inflammation appears, ultrasound inspection has higher diagnosis rate than FDS if combined with clinical symptom;Third : When the disease is hard to be identified with breast cancer , FDS is a more significant examination if we consider clinical characteristic.
