Mastitis during lactation, mostly due to Gram-positive bacterial infections, has a rapid onset and short course, and if not treated promptly, abscesses can form within a short period of time. The treatment of abscesses is abscess incision and drainage, but the damage to the milk ducts and the impact on the shape of the breast caused by the surgery are unacceptable to many young women. In 1996, O’Hara et al. advocated ultrasound-guided puncture and aspiration of abscesses with significant results. In China, Chinese medicine has explicitly included puncture aspiration in the guidelines for the treatment of canker sores, and puncture aspiration is a very mature technique. However, due to legal restrictions on the use of antibiotics in local administration. Since puncture aspiration alone may have the potential for recurrence, our department treats lactational mastitis with abscess formation more effectively by combining puncture aspiration with oral Chinese medicine and acupuncture point physical therapy. In foreign reports, puncture aspiration for lactational breast abscess is unsuccessful when the abscess cavity is larger than 50 ml. However, pus aspiration combined with herbal medicine and acupuncture points for the treatment of breast abscess is effective in our department for treating a large amount of 60 to 130 ml, the largest amount being 130 ml, with a short course of treatment, less pain and less damage.
