Abstract:Objective To analyze the clinical characteristics and treatment of idiopathic granulomatous mastitis (IGM) with recurrence in the short term (within 1 year) after cure. Methods Seventy patients with pathologically confirmed IGM admitted to the department of breast surgery of Changzhi People′s Hospital of Shanxi Province and Shanxi Dayi Hospital from January 2017 to June 2018 were selected as the study subjects, among which 42 cases were treated with combination therapy (drugs + surgery) and 28 cases were treated with surgical treatment alone. Patients were divided into the relapsing group (14 cases) and the non-relapsing group (56 cases) according to whether they had relapsed within 1 year of cure. The clinical characteristics and treatment methods of the two groups were compared. Results There were statistically significant differences in body mass index with or without abscess fluid and with or without fistula (sinus tract) between the two groups (P < 0.05). There was no significant difference in age, lactation time and mass size between the two groups (P > 0.05). After multi-factor analysis, surgery alone and high body mass index were independent risk factors for recurrence (P < 0.05). The risk of recurrence in patients who received surgical treatment alone was 7.8 times higher than that in patients receiving combined treatment, and the risk of recurrence in obese patients was 1.3 times higher than that in other patients. Conclusion Patients with obesity, breast abscesses and fistula (sinus tract) formation, and surgical treatment alone have a higher risk of short-term recurrence. Surgical treatment alone and obesity are independent risk factors for recurrence after treatment.
