RESUMO
Objective To study the application effect of ENCOR vacuum-assisted breast minimally invasive polypectomy system in the diagnosis and treatment of breast tumors. Methods Totally 86 breast cancer patients treated in the General Hospital of Yangmei Group from January 2017 to October 2017 were randomly divided into study group and control group,with 43 cases in each group. The study group was treated with ENCOR vacuum-assisted minimally invasive rotational atherectomy system,while the control group was treated by traditional breast excision. The operative conditions, postoperative complications and postoperative recurrence were observed and compared between the two groups. Results The intraoperative bleeding volume,operation time,scar length and postoperative recovery time in the study group were (5.1 ±1.2)mL,(15.9 ±3.5)min,(0.3 ±0.1)cm,(2.7 ±0.4)d,respectively, which in the control group were (12.7 ±2.3)mL,(26.8 ±4.6)min,(3.2 ±1.1)cm and (5.1 ±0.8)d,respectively, the differences between the two groups were statistically significant ( t=15. 579,14. 297,14. 108,13. 597,all P<0. 05). The total incidence rate of postoperative complications in the study group was 11. 63％,which was significantly lower than 30. 23％ in the control group (χ2 =5. 187,P<0. 05). During the follow-up of 12 months,in the study group,2 patients (4. 65％) had residual tumor,1 patient (2. 33％) developed recurrence; in the control group, 3 patients (6. 98％) had residual tumor,2 patients (4. 65％) developed recurrence. There was no statistically significant difference between the two groups (χ2 =1. 013,P >0. 05). Conclusion ENCOR vacuum - assisted breast minimally invasive revolving system in the treatment of breast tiny tumors has advantages of less trauma and pain,rapid recovery,etc,it is safe and effective.
RESUMO
Objective To investigate the corrective effect of modified Brisson technique to treat concealed penis in children.Methods From July 2014 to July 2016,selected 12 patients (3-10 years old,mean 7.2 years old) with concealed penis were surgically treated with the modified Brisson technique in the Second Affiliated Hospital of Nanjing Medical University.Their clinical manifestations included the penis buried below the surface of prepubic skin which can be palpated and visualized through pushing the skin around the penis to the pubis and the short foreskin which was not attached to the penile corpus cavernosum.Patients with other conditions such as obesity and penial agenesis that caused buried penis were excluded from the study.The modified Brisson technique consisted of 4 steps.Ventral incision was used to gradually slit the narrow ring of the prepuce and to expose the glans followed by circumfe-rential inner foreskin incision made below the coronary sulcus of penis then the foreskin stripping released the corpus cavernosum.Finally the skin coverage was accomplished by posthioplasty.The operation time,blood loss,complications,postoperative treatments and followed-ups were retrospectively analyzed.Results For all the 12 patients,the operations were successful,lasting 40 to 60 minutes.The bleeding was about 5 to 10 mL and there was no operation-related complications like bleeding and infection of incision.Satisfactory cosmetic outcomes were obtained without retraction and the scars were similar to those of circumcision.All patients had penile lymphedema postoperatively which disappeared within 6 months after operation.Follow-up ranged from 6 months to 1 year,and there were no complications like skin necrosis and contracture or voiding difficulty.Conclusions The modified Brisson technique for concealed penis repair is technically easy and safe.In addition,it provides a good cosmetic appearance,functional outcomes and excellent postoperative satisfaction grades.
RESUMO
The indication for treating adolescent idiopathic scoliosis (AIS) including development states, bending types, spinal rotation, as well as degree of deformity, but the orthosis occasionally involves in clinic. The third generation internal fixation system, such as CD, TSRH, and Chinese Greatwall system arose more attention with the advancement of spinal cube theory and internal fixation technique. Surgical treatment of scoliosis by fixation of the vertebral pedicle has superior effect in treating deformity at the sagittal/coronal plane or vertebra rotation, which can correct the three dimensional deformities of spinal column and improve patient's back appearance via revolving controlled rod.
