ABSTRACT
Objective To explore the significance of palpation-negative breast tumor resection with ultrasound-guided methylene blue labeling and percutaneous suture traction.Methods 46 cases of small breast tumors with the diameter from 0.5 cm to 1.0 cm were double labeled with methylene blue under the guide of ultrasound l hour preoperatively.The tumors were fixed,drew outward with percutaneous suture and resected accurately.All the 46 cases were rechecked by ultrasound to verify whether residual or false resection occurred 1 month later.Results All the 58 tumors of the 46 patients were accurately resected.No residue or false resection occurred.The average operation duration was 10 min to 20 min.Conclusion Palpable-negative breast tumor resection with ultrasound-guided methylene blue labeling and percutaneous suture traction has the advantages of small invasion,accurate positioning and short operation duration.
