Importance of systemic mediastinal lymphadenectomy in exact staging of bronchogenic carcinoma

The clinical value of a new method of functional lymph node dissection in video-assisted thoracic surgery right non-small cell lung cancer radical resection

Background

To evaluate the safety, thoroughness and feasibility of "tunnel-type en bloc mediastinal lymph node dissection" in video-assisted thoracic surgery (VATS) for right non-small cell lung cancer (NSCLC) radical resection, which functionally dissected the lymph nodes of station 2R/4R/7.

Methods

A retrospective study was performed in the clinical data of 196 patients with VATS right NSCLC radical resection. According to the different methods of lymph node dissection of station 2R, 4R and 7, they were divided into the tunnel-type group (n=102) and the routine group (n=94). The clinical data of two group were compared.

Results

The analyses of the baselines of the two groups are comparable. For lymph nodes dissection of station 2R/4R/7, operation time, the total number, positive number and metastasis incidence shown no significant difference between two groups (P>0.05). However, the amount of bleeding, postoperative thoracic drainage volume, extubation time, hospitalization days, the incidence of postoperative pulmonary infection and chronic cough were significantly lower in the tunnel-type group (P<0.05). There was no significant difference in 3-year recurrence and metastasis and in 3-year survival between tunnel-type group and routine group.

Conclusions

The tunnel-type group has more advantages, such as less surgical trauma, shorter hospitalization time, faster postoperative rehabilitation, even less postoperative chronic cough compared with the routine group. Therefore, we believe that the tunnel-type en bloc mediastinal lymph node dissection is a safe, thorough and feasible surgical method, which is worthy of being popularized and applied in the VATS right NSCLC radical resection.

Alginate Dressing Application in Hemostasis After Using Seldinger Peripherally Inserted Central Venous Catheter in Tumor Patients

The aim of this study is to observe hemostatic effects of alginate dressing after using seldinger PICC catheter in tumor patients. Sixty tumor patients with PICC receiving chemotherapy were divided into the test group (30 cases) and the control group (30 cases) randomly. The test group was treated with alginate dressing and oppressed by the puncture point, while the control group was treated with gauze of the same size. PICC transparent films were used in both groups. Finally, dressing ooze blood soaked states on the puncture points and dressing change times were observed in the two groups for 1 week. Moreover, local infection rate and incidence of catheter leak were also evaluated. The results showed that the oozing of blood and the changing frequency in the test group were obviously less than that in the control group, and there has a statistical difference (P < 0.05). Infection rate of puncture point and incidence of catheter leak were simultaneously reduced in the test group. Alginate dressing is effective in preventing seldinger PICC catheter-induced hemorrhage.
