ABSTRACT
Objective To investigate application value of two vacuum assisted biopsy systems in benign breast lesions and compare the advantages and disadvantages of EnCor and Mammotome system.Methods Vacuum assisted excision was performed on 346 benign breast lesions in 227 patients (EnCor with 103 cases, Mammotome with 124 cases) from November 2012 to May 2013, including 162 cases using EnCor system and 184 cases using Mammotome system.Results Duration of operation in EnCor group was (14.18± 4.21) minutes,in Mammotome group was (18.77 ± 7.06) minutes, and the difference was significant (P ＜ 0.001) .Weight of tissues in Mammotome group was (6.87± 3.43) g, in EnCor group was (8.32± 1.18) g, and the difference was significant (P ＜ 0.001).No significant differences were found in postoperative hematoma (P =0.58), postoperative pain (P =0.35), incidence of residual tumor (P =0.15).Conclusion Compared Mammotome group, EnCor group had significantly shorter duration.But using Mammotome system, the specimens can be observed directly.Mammotome is more suitable for women of childbearing age, it can preserve lactation function.There is no significant difference in complication and residual tumor of two vacuum assisted biopsy system in benign breast lesions.
ABSTRACT
Objective To study the EnCor vacuum negative pressure rotary system in ultrasonic BI-RADS 2~3 scale mammary gland disease application value.Methods Under the guidance of ultrasound, the application EnCor vacuum negative pressure rotary cutting system for 142 patients, 366 cases of breast lesion resection, specimens sent to pathological examination.Results A total of 366 breast lesions, 359 complete resection, the success rate was 98.1%, 2 transit operation, and transfer rate was 0.5%, 5 partial nephrectomy, residual rate was 1.4%.359 complete resection of the pathological results for breast malignant lesions in 4, the infiltrating ductal carcinoma 1, 3 ductal carcinoma in situ;breast benign lesions in 355, of which 132 breast fibroadenoma, adenosis with adenoma formation of 60, 99 breast adenosis, breast adenosis with duct expansion 43, 11 breast intraductal papilloma, one with four individual catheter atypical increase the living.Two transit operation pathological results were fibroadenoma, 5 disease of partial nephrectomy for adenosis with duct expansion.Conclusions The excision of breast neoplasm EnCor vacuum negative pres-sure rotary cutting system, not only small trauma, good cosmetic effect, and reduce misdiagnosis and im-prove the patients'satisfaction.
