International Journal of Surgery 2012;39(11):763-765
Objective To explore the clinical significance of occult breast lesions biopsy,determine the operating methods of ultrasound-guided precisie resection of occult breast lesions,improve early diagnosis rate of breast cancer.Methods Forty-eight occult breast lesions of 44 patients were reviewed by localization-needle and skin markers method under ultrasound-guided,and the lesions were removed surgically according to the fixed steps.Results It was confirmed that all the impalpable mammary masses were exactly excised without localization-needle fracture or prolapse through postoperative pathological diagnosis.Breast appearance had no change after the operation.No nipple-areola necrosis occurred.The pathology results showed 4 cases of invasive ductal carcinoma (Ⅰ stage),the incidence rate being 8.3%,and 15 cases of atypical hyperplasia,the incidence rate being 31.3%.The other types were benign disease such as adenosis,intraductal papilloma,fibroadenoma and mammary duct ectasia.Conclusions Ultrasound-guided precise resection of occult breast lesions is a safe and effective diagnosis and treatment method,which needs some surgical skills.It has positive significance in improving breast cancer early diagnosis rate,reducing medical costs and decreasing breast biopsies complications.

MethodEndoscopic thyroidectomy via breast areola approach was performed in 62 patients, including 16 cases of adenoma, 43 cases of nodular goiter, and 3 cases of thyroid carcinoma.ResultsEndoscopic thyroidectomy was succeeded in 62 patients, 2 cases of cutaneous emphysema, 1 case of light skin bum which diameter was 0.5 cm, 1 case of transient hoarse voice,and 1 case of puncture sinus tract bleeding. There was no converted to open surgery,no hypercapnia, no damage of recurrent laryngeal nerve or parathyriod glands. ConclusionEndoscopic thyroidectomy via breast areola approach is safe and effective,and has good cosmetic results.

Objective To observe the effect of Arm Spasticity Inhibitor worn in rehabilitation training on patients with upper extremities spasticity and shoulder subluxation after stroke. Methods 80 stroke patients with flexor spasm in upper extremities complicated with subluxation of shoulder were divided into treatment group and control group equally. Both groups accepted routine medicine and rehabilitation, and the treatment group wore the Arm Spasticity Inhibitor developed ourselves during the rehabilitation training. Their acromio-humeral interval (AHI) was measured with the X- ray; and they were assessed with modified Ashworth Scale (MAS), range of motion of shoulder (ROM) and elbow before and 2 months after treatment. Results It improved more in the AHI, score of MAS and ROM in the treatment group than in the control group after treatment (P<0.001). Conclusion Wearing Arm Spasticity Inhibitor during rehabilitation training may release the spasticity of upper extremities and shoulder subluxation, and improve shoulder function in patients after stroke.

Objective To analyze the clinical efficacy of the laparoscopic breast-conserving surgery combined with radiofrequency ablation to treat the early-stage breast cancer.Methods We collected 55 patients diagnosed early-stage breast cancer in retrospect,which started from January 2014 to December 2016.Twenty-seven of them were performed the laparoscopic breast-conserving surgery combined with radiofrequency ablation while others went through laparoscopic breast-conserving surgery without radiofrequency ablation.Meanwhile,we adopted the student t-test and the chi-square test to compare results of two groups.More specific,the main indexes of this study are including the post-operative local recurrence,the incidence of fat liquefaction or the incision-infection,operation time,post-operative hospital stay and the hospitalization expense.Results The laparoscopic breast-conserving surgery combined with radiofrequency ablation group had low local-recurrence than the laparoscopic breastconserving surgery group (0 and 7.69%).Additionally,there were no statistical differences between two groups in the incidence of fat liquefaction.However,The laparoscopic breast-conserving surgery combined with radiofrequency ablation group had more hospitalization expense than the laparoscopic breast-conserving surgery group [(4.1 ± 0.7) ten thousand yuan and (2.3 ± 0.6) ten thousand yuan,P < 0.05].Conclusions Although the laparoscopic breast-conserving surgery combined with radiofrequency ablation group remarkably increased the hospitalization expense because of the utility of the radiofrequency ablation related apparatus,it may provide the probability of shaving more residual tumor cell and may low down the recurrence,especially not rising up the incidence of the post-operative fat liquefaction.Therefore,this surgery method might be one of the potential developments in the minimal-invasive of early stage breast cancer.

Objective To analyze clinical characteristics of invasive Luminal subtype breast cancer.Methods The data of 162 invasive Luminal subtype breast cancer patients receiving operation in Cancer Hospital of Chinese Academy of Medical Science from January 1 st to September 30th in 2002,were collected and the clinical characteristics,recurrences,metastasis and survivals were retrospectively analyzed.Results The median time of follow-up was 92 months,ranging from 4 to 98 months.41 cases (25.3%,41/162) presented local recurrence or metastasis including 32 cases with metastasis ( 19.8%,32/162),2 cases with local recurrences (1.2%,2/162) and 7 cases with both local recurrence and metastasis (4.3%,7/162) ;Disease-free survival (DFS) and the 5-year DFS were 73.1% and 79.6%,respectively.27 patients ( 16.7%,27/162) died of breast cancer,the overall survival (OS) and 5-year OS were 82.5% and 85.3%,respectively.According to Kaplen-Meier survival analysis,tumor size,lymph node status and clinical stage were correlated to overall survival time ( P < 0.05 ) ; and rumor size,lymph node starus,grade,clinical stage and PR status were correlated to disease-free survival time ( P < 0.05 ).By multivariate analysis,TNM stage,PR and PCNA were independent prognostic factors correlated to overall survival time (OR=0.633,95% CI:0.411 -0.976,P<0.05; OR =0.823,95% CI:1.012-3.283,P < 0.05) ; TNM stage and PR was independent prognostic factors correlated to disease-free survival time (OR =3.273,95% CI:1.719 - 6.232,P < 0.01 ; OR =0.599,95% CI:0.423 - 0.850,P < 0.01 ).Conclusions In invasive Luminal subtype breast cancers,PR is correlated to fine prognosis,and PCNA is correlated to overall survival time.
