乳管造影術(Galactography)是一項輔助性乳房攝影(Mammogr-aphy),使用含碘造影劑自乳頭直接注射入乳管,以分析乳管是否正常,對於婦女乳頭有不正常分泌,如出血、漿液性分泌物等,可提供重要的影像診斷依據。本文收集45位乳頭有異常分泌的婦女,施以乳管造影術結果分析出其原因為各種乳管異常,包括佔最多數的管內乳突瘤(intraductal papilloma)有33%(15/45),管內乳突狀瘤病(intraductal papillomatosis)15%(7/45),乳管擴張症(ductal ectasia)13%(6/45),纖維囊腫病(fibrocystic disease)29%(13/45),乳癌5%(2/45),正常15%(2/45),此結果相當有效地以影像學診斷找出病灶的位置、原因及範圍,以幫助外科作進一步之處理,由於操作方法簡單、容易、安全,臨床診斷價值頗獲肯定。
Galactography, a procedure involving injection of contrast medium into the lactiferous ducts, is the well known method for preoperative determination of the nature, location, and extent of lesions causing abnormal nipple discharge. It is particularly valuable when there are no other symptoms and neither physical examination nor mammography reveals the underlying cause. In Taiwan, however, the value of this examination in Chinese women has not yet been thoroughly evaluated. In this paper, we present our experience with 45 cases to evaluate the procedure as well as the nature of the lesions including intraductal papilloma in 33% (15/45), ductal ectasia in 13% (6/45), intraductal papillomatosis in 15% (7/45), fibrocystic disease in 29% (13/45), carcinoma in 5% (2/45) and normal in 5% (2/45). We also review the indications, technique, reliability, and clinical relevance of galactography.
