Central duct excision
Central duct excision (also: ''major duct excision'' or ''Hadfield's procedure'') is the surgical removal (excision) of all lactiferous duct under the nipple. The excision of a single duct is called microdochectomy, a mere incision of a mammary duct (without excision) is ''microdochotomy''.〔(【引用サイトリンク】title=Microdochotomy )〕
== Indication ==
Central duct excision is a standard treatment of in case there is nipple discharge which stems from multiple ducts or cannot be traced back to a single duct. It is also indicated if there is bloody nipple discharge in patients beyond childbearing age.
Duct excision may be indicated for the treatment of recurrent breast abscess and mastitis,〔, p. 1694〕 and the total removal of all ducts from behind the nipple has been recommended to avoid further recurrence. In particular if the patient wishes to preserve breastfeeding ability, the condition of the mammary duct system is investigated by means of galactography (ductography) or ductoscopy in order to determine whether the excision of a single duct (microdochectomy) would be sufficient.〔
Pre-operatively, also breast ultrasound and mammogram are performed to rule out other abnormalities of the breast.〔
