A clinical study on the treatment of granulomatous lobular mastitis by the external application of the internal pus-expelling decoction and operation.

Background: The objective of this study was to evaluate the clinical efficacy of the external application of internal expulsion pus-expelling decoction (IEPED) combined with surgery in the treatment of granulomatous lobular mastitis (GLM).

Methods: A total of 110 patients in our hospital with sepsis GLM were randomly divided into two groups: treatment group (n=60, the wound was treated with IEPED) and control group (n=50, the wound was not treated with IEPED). We assessed the recurrence, contra lateral breast form, and aesthetic evaluation of the patients in the two groups.

Results: The total effective rates in the patients in the treatment group and the control group were 90% and 68%, respectively, after the preoperative pretreatment and before radical surgery (P<0.05). After 10 days of receiving the debridement treatment, the two groups were compared in term of physical signs scores and the difference was statistically significant (P<0.05). Within one year of the regular follow-up after treatment, 0 case recurred in the treatment group and 1 case recurred in the control group (P>0.05). In the treatment group, 30 cases showed excellent results in the aesthetic evaluation of breast appearance, 18 cases were good, and the overall excellent and good rate was up to 80%. In the control group, 12 cases showed excellent results and 16 cases showed good results, with the overall excellent and good rate reaching 56% (P<0.05).

Conclusions: In patients with abscess debridement of GLM, the external application of IEPED can significantly reduce the primary lesion of patients with abscess GLM, reduce the surgical resection area, and maximize the preservation of the patients' breast appearance.
