Mammotome 생검 후 수술적 재절제술을 시행한 유방종양에 대한 병리조직학적 결과
조영업 한국유방암학회 2007 Journal of breast cancer Vol.10 No.4
Purpose: The Mammotome biopsy is a relatively new surgical technique that is a minimally invasive image-guided procedure, requiring a small incision that produces a barely noticeable scar. The technique is a useful method for the surgical biopsy of properly selected patients. We reviewed the pathology of the biopsies for the proper selection of a mammotome biopsy in patients with re-excised breast tumors. Methods: During a 24-month period, we performed vacuumassisted breast biopsies for 277 likely benign breast lesions using ultrasound and fine-needle aspiration cytology or a core needle biopsy, in 203 patients. The age of the patients ranged from 15 to 67 yr (average age 36.6 yr), and the average size of the lesions was 2.39±1.06 cm (minimum size 0.5 cm, maximum size 5.0 cm). We retrospectively analyzed the pathological findings of the re-excised breast lesions. Results: The pathology of ultrasound-guided vacuum biopsies of the benign-appearing breast lesions were fibroadenomas (69.7%), intraductal papillomas (6.1%), fibrocystic disease (7.9%), phyllodes tumors (2.9%), malignant tumors (1.4%), ductal hyperplasia (2.9%), and other benign diseases (9.1%). Re-excision by a conventional method was performed for nine patients. Reasons for re-excision were the presence of five proven malignancies (a malignant phyllodes tumor in 2 cases, a tubular carcinoma in 1 case, a papillary carcinoma in 1 case and a ductal carcinoma in situ [DCIS] in 1 case), a possible atypical ductal hyperplasia (ADH) malignancy, two marginal involvement in phyllodes tumors and the possible extension of a lesion as an atypical papilloma. In the re-excised specimens, residual tissues were noticed in eight cases. An ADH lesion was proven as a DCIS. Conclusion: A case of suggested marginal involvements and/or a possible malignancy should be re-excised because of the high possibility of remnant lesions being present after the mammotome biopsy. The cytological and pathological review must be performed precisely before performing the mammotome procedures with considering of the clinical and radiological findings.

Purpose: Endoscopic thyroidectomy (ET) requires a proper working space for adequate visualization of anatomical structures and proper instrument manipulation. The purpose of this prospective study was to estimate the feasibility and safety of ET using an anterior chest wall approach without gas insufflation. Materials and Methods: The working space was created under a direct and endoscopic view through a 3-cm incision on the anterior chest wall. A retracting device was then inserted to establish the working space, and subsequent procedures were performed endoscopically. All data were reviewed using a prospective database. Results: We performed 30 ETs in patients with benign thyroid tumors from December 2003 to December 2005. The procedures were completed successfully in 29 patients (mean operative time: 160.6 min; range: 90-345 min). One patient with ET was converted to open thyroidectomy secondary to substernal extension of the tumor. None of the patients developed permanent postoperative hypocalcemia or recurrent laryngeal nerve paralysis. Three patients exhibited some degree of transient recurrent laryngeal nerve palsy. Conclusion: These data suggest that gasless ET using an anterior chest wall approach is safe and feasible in selected patients for treating benign thyroid tumors. This technique may offer good operative working space when performed by surgeons with relatively low-volume ET practices.
