Therapeutic Effect Of Ultrasound-Guided Rotary Cutting On Benign Breast Tumors And Factors Related To Postoperative Hematoma

Background: The ultrasound-guided rotational cutting of benign breast tumors is widely accepted by many patients, but the postoperative hematoma is the most common complication. This study aimed to investigate therapeutic effect of ultrasound-guided rotary cutting on benign breast tumors and analyze the factors related to postoperative hematoma. Methods: Four hundred and twelve patients with 516 benign breast masses were enrolled in this study. The ultrasound-guided rotary cutting of breast masses was performed. The surgical outcome was evaluated, and occurrence and prognosis of postoperative hematoma were observed. The binary logistic analysis and Pearson correlation analysis were performed on the factors influencing the postoperative hematoma formation. Results: All 516 masses were completely removed using ultrasound-guided rotary cutting, without any residue. The success rate of surgery was 100%. The ultrasound examination at postoperative 24-48 h showed that, the hematoma with diameter >= 1.0 cm was seen in the surgical area in 43 patients, but after 6 months, the hematoma was completely absorbed in all 43 cases. Binary logistic analysis showed that, the cutting times, mass volume, mass depth, resected mass number and postoperative bandage compression time had significant influence on the occurrence of postoperative hematoma (P < 0.05). Pearson correlation analysis showed that, the cutting times, mass volume, mass depth and resected mass number were positively correlated with the hematoma formation, respectively (P < 0.05), and the postoperative bandage compression time was negatively correlated with the hematoma formation (P < 0.05). Conclusion: The ultrasound-guided rotary cutting can obtain satisfactory therapeutic effect on benign breast tumors. In this technique, the cutting times, mass volume, mass depth, resected mass number and bandage compression time are the major risk factors for postoperative hematoma formation. The screening of enrolled patients and taking targeted measures during the surgery can effectively reduce the occurrence of postoperative hematoma.
