Abstract： Objective To investigate the effect of singledirection lobectomy plus systematic lymphnode dissection for primary nonsmall cell lung cancer (NSCLC) in the early stage by videoassisted thoracic surgery (VATS). Methods We retrospectively analyzed the clinical data of 89 patients who received VATS lobectomy plus systematic lymphnode dissection for earlystage primary NSCLC in the Second People’s Hospital of Chengdu between June 2006 and December 2009. Based on the operative approach, the patients were divided into two groups: VATSminithoracotomy group and singledirection lobectomy VATS group. In the former group, there were 46 patients, including 36 males and 10 females, with an age of 58.76±14.78 years. For patients in this group, minithoracotomy was carried out assisted by VATS. In the latter group, there were 43 patients, including 37 males and 6 females, with an age of 61.34±12.56 years, and singledirection lobectomy VATS was performed for patients in this group. Moreover, 42 patients undergoing routine posterior lateral open thoracotomy were chosen to form the control group (thoracotomy group, included 37 males and 5 females with an age of 56.30±15.59 years). The clinical features, such as operative time, operative blood loss, the number of systematic dissected lymph nodes, postoperative drainage quantity, postoperative complications and visual analogue scale (VAS) of chest pain were retrospectively analyzed to evaluate the early outcomes. Results No operative death occurred in all three groups. There were significant differences among the three groups in the postoperative drainage time (P=0.024), postoperative drainage quantity (P=0.019), operative blood loss (P=0.009), early outofbed activity time (P=0.031), and the incidence of cardiopulmonary complications (P=0.048). Compared with the VATSminithoracotomy group, the singledirection lobectomy VATS group was significantly lower or shorter (Plt;0.05) in postoperative drainage quantity (208.33±50.39 ml vs. 245.98±45.32 ml), operative blood loss (78.79±24.23 ml vs. 112.63±64.32 ml), and the early outofbed activity time (2.31±0.27 d vs. 3.56±0.31 d). The rate of using Dolantin in the control group was significantly higher than the other two groups (P=0.046, 0.007). The change of VAS score among the three groups after operation was also statistically significant (F=5.796, P=0.002). A total of 109 patients (37 in the VATSminithoracotomy group, 37 in the singledirection lobectomy VATS group, and 35 in the control group) were followed up after operation with a period of 2 to 48 months. Twentytwo patients were lost in the followup. There were 10, 9, and 8 deaths during the followup in the three groups respectively, and the median survival time was 40 months, 37 months, and 37 months respectively. There was no significant difference among the three groups in survival time (P=0.848). Conclusion VATS, especially VATS assisted single direction lobectomy and systematic lymphnode dissection for primary NSCLC in the early stage has the same surgical efficacy as the traditional open thoracotomy, and is minimally invasive, which contributes to a quick recovery. Consequently, it is a reliable approach for lung cancer in the early stage.
Objective To investigate and evaluate prevention and treatment of seroma by transposition of tissue flaps and Arista hemostatic powder after regional lymph node resection in patients with malignant tumors. Methods Twelve patients (6 males, 6 females; aged 31-81 years, with metastatic tumors underwent prevention and treatment of seroma with the tissue flaps and Arista hemostatic powder spray after regional lymph node resection. The metastatic tumors involved the axilla in 1 patient with breast carcinoma, the iliac and inguinal regions in 2 patients with carcinomas of theuterine cervix and the rectum, and the inguinal region in 9 patients, including4 patients with malignant fibrous histiocytoma（3 in the thigh, 1 in the leg）,2 patients with squamous carcinomas in the leg, 1 patient with synovial sarcomain the knee, 1 patient with epithelioid sarcoma in the leg, and 1 patient with malignant melanoma in the foot. As for the lymph node removal therapy. 1 patientunderwent axillary lymph node removal, 2 palients underwent lymph node removal in theiliac and inguinal regions, and 9 patients underwent lymph node removal inthe inguinal region. Meanwhile, of the 12 patients, 6 patients underwent transpostion of sartourius flaps with Arista hemostatic powder, 3 patients underwent transposition of the rectus abdominis myocutaneous flaps (including 2 patients treatedwith Arista spray befor the wound closure and 1 patient treated by transposition of local skin flaps with Arista spray used again),and 3 patients underwent only the suturing of the wounds combined with Arista. At the same time, of the 12 patients,only 4 patient underwent the transplantation of artificial blood vessels. Results The follow-up for 2-10 months after operation revealed that 10 patients, who had received the transposition of tissue flaps and the spray of Arista hemostatic powder, had the first intention of the incision heal with seroma cured. Nine patients were given a preventive use of Arista hemostaticpowder and therefore no seroma developed. The combined use of the transpositionof tissue flaps and Arista hemostatic powder spray achieved a success rate of 100% in the prevention or treatment of seroma. However, 1 patient developed microcirculation disturbance 24 hours after operation and underwent disarticulation of the hip; 1 patient developed pelvic cavity hydrops and died 10 months after operation. Conclusion The combined use of transposition of tissue flaps and Arista hemostatic powder spray can effectively prevent or treat seroma after regional lymph node removal in a patient with malignant tumor.

Methods Twenty-seven patients treated by breast-conserving surgery from February 2007 to February 2011 in our hospital were divided into endoscopy-assisted axillary lymph node dissection group (the EALND group, n=11) and conventional axillary lymph node dissection group (the CALND group, n=16). Then, we compared the operation time, intra-operative bleeding volume, number of lymph nodes dissected, postoperative drainage time and amount between the two groups. Results The operation time was significantly longer in the EALND group than that in the CALND group [(186.36±11.20) vs. (158.13±25.29) minutes, P=0.002]. The intra-operative bleeding volume of the EALND group was significantly less than that of the CALND group [(61.82±51.54) vs. (103.75±42.56) mL, P=0.030]. There were no significant differences between the two groups in the number of lymph nodes dissected, postoperative drainage time and amount. Follow-up was done for one month to four years, during which no local recurrence or trocar displacing occurred. Conclusion The breast-conserving resection and endoscopy-assisted axillary lymph node dissection can be safely used in early breast cancer patients, and surgical skills should be mastered in the study.
Objective To explore the pattern and clinical influencing factors of cervical lymph node metastasis in papillary thyroid carcinoma （PTC）， and provide a basis for the choice of surgical approach for the PTC neck lymph node processing. Methods The clinical data of 98 patients with PTC treated in Affiliated Hospital of Guiyang Medical College from Jan. 2009 to Dec. 2011 were collected， and the pattern and clinical influencing factors of cervical lymph node metastasis were analyzed. Results Ninety eight consecutive patients underwent neck dissection in a total of 114 sides. The lymph node metastasis rate of cervical lymph node， districtⅥ， districtⅡ＋Ⅲ＋Ⅳ， and districtⅤwas 77.55% （76/98）， 74.49% （73/98）， 42.86% （42/98）， and 5.10% （5/98）， respectively. Results of univariate analysis showed that lymph node metastasis rates were higher in patients with diameter of tumor greater than 1 cm， tumor invaded thyroid capsule， multi-focal tumor， and old than 45 years （P＜0.05）. Results of multivariate analysis showed that the age of patients， diameter of tumor， tumor invaded thyroid capsule， and multifocal tumor were independent risk factors of cervical lymph node metastasis （P＜0.05）. Tumor invaded thyroid capsule， multifocal tumor， combined with districtⅥmetastasis， and combined with districtⅡ＋Ⅲ＋Ⅳ metastasis were independent risk factors of prelaryngeal lymph node metastasis （P＜0.05）. Tumor invaded thyroid capsule and multifocal tumor were independent risk factors of skip lymph node metastasis （P＜0.05）. Conclusions DistrictⅥ is found to be the predominant site for lymph node metastasis of PTC， the districtⅢ and the districtⅣinvolved in addition， so it is necessary to clean lymph nodes at districtⅥ routinely. The regularity of cervical lymph node metastasis can provide the basis for surgeon to choose a reasonable type of neck dissection.

ObjectiveTo summarize the new ideas and new instruments in thyroid surgery. MethodsRelated literatures were reviewed and analyzed. ResultsTotal thyroidectomy had become the preferred option for differentiated thyroid cancer and multiple nodule goiter. The key change of surgery was from recurrent laryngeal nerve-protection to parathyroid-protection. Harmonic scalpel, bipolar coagulation forceps and Ligasure were used to thyroid surgery, which could shorten operation time and reduce operative bleeding. ConclusionThe ideas and techniques of thyroid surgery have changed, total thyroidectomy and parathyroid protection are being paid more and more attentions, and new instruments are used more extensively in thyroid surgery.
