Objective To analyze therapeutic effect of ultrasound-guided vacuum-assisted rotary excision with tube irrigation drainage in treatment of granulomatous mastitis (GM).Methods The clinical data of 120 patients with GM from January 2018 to December 2018 in the Renmin Hospital of Wuhan University were analyzed. Sixty patients were treated with the ultrasound-guided vacuum-assisted rotary excision with tube irrigation drainage (control group), and the other 60 patients were treated with the metronidazole solution combined with dexamethasone on the basis of the control group (observation group). The therapeutic period, total effective rate, postoperative appearance of breast, and recurrence rate were analyzed. While the pathogenic bacteria was analyzed by the microbial culture and the pathogen gene detection.Results There were no significant differences in the baseline data between the two groups (P>0.05). The ultrasound-guided vacuum-assisted rotary excisions were successfully performed in all 120 patients. The therapeutic period of the observation group was shorter than that of the control group (t=–3.633, P<0.001). The total effective rate and rate of excellent and good of postoperative breast appearance had no significant differences between the two groups (total effective rate: 96.7% versus 90.0%, χ2=1.922, P=0.166; rate of excellent and good of postoperative breast appearance: 96.7% versus 88.3%, χ2=1.205, P=0.272). The recurrence rate of the observation group was lower than that of the control group (χ2=5.175, P=0.023). The positive rates of bacteria were 25.8% and 58.8% in the 120 cases by the microbial culture and 52 cases by the pathogen gene detection, respectively, which had a statistical difference (χ2=16.974, P<0.001), the same conclusions were obtained in the observation group and the control group (χ2=6.691, P=0.010; χ2=9.379, P=0.002).Conclusions Ultrasound-guided vacuum-assisted rotary excision with tube irrigation drainage is well applied in treatment of GM. It could maintain a good shape of breast. Use of metronidazole solution combined with dexamethasone after surgery could shorten therapeutic period and reduce recurrence rate.
