Ductal Lavage Versus Corticosteroids Therapy for Idiopathic Granulomatous Mastitis

The patients received ductal lavage and breast massage every other day for two weeks. We used lidocaine (1%) for local anesthesia around the nipple. We used a lacrimal probe to identify 4-5 openings in the lactiferous ducts on the nipple and inserted the infusion cannula (21-23G). A total of 25ml of irrigation solution (5 ml of 2% lidocaine, 40 mg of triamcinolone acetonide, 20 ml of 0.9% saline and 1.0 g of ceftriaxone) was pumped into the ducts over 20-25 minutes. The patient returned to the clinic the next day for breast massage, and the cycle was repeated for two weeks.

Methylprednisolone(Common brand names: Medrol) or prednisone 20-40mg, qd for two weeks, then temper the dose gradually, and then 20mg qd for maintenance (The total duration of the treatment is 6 months).
