探讨超声引导下应用麦默通旋切术切除乳腺良性肿物的临床应用价值。

235例良性乳腺疾病患者共410处乳腺肿块，在超声引导下行麦默通微创旋切术，肿块直径0.5~5.0 cm，对直径≥3 cm的肿物行微创旋切术后，于靠近病灶的乳晕旁切开约1.5 cm切口探查残腔，确保已切除残余病灶。术后随访6~9个月。

235例患者的乳腺肿物被完全切除，术后5例出现血肿形成，2例出现肿物表面皮肤凹陷，3例复发。

超声引导下麦默通旋切术切除0.5~3 cm乳腺良性肿块是安全和有效。值得临床推广应用。

To investigate the clinical effect of benign breast mass resected by ultrasound-guided Mammotome minimal invasive biopsy system.

Four hundred and ten benign breast masses of 235 cases ranged from 0.5~5.0 cm were enrolled in study. The masses with the diameter lager than 3.0 cm were at the same time cut-off with a incision 1.5 cm long besides areola of breast to see if there were remnants. All cases were followed up for 6~9 months after the operations.

All masses were completely removed. Hematoma formation of 5 cases, skin depression of 2 cases and recurrence of 3 cases were observed.

Ultrasound-guided Mammotome minimally invasive system is suitable for resection of 0.5~3.0 cm benign breast masses. Making a short incision beside the mass can cut down the rate of residual when removing the mass larger the 3.0 cm with ultrasound-guided Mammotome minimally invasive system.
