RESUMO
@#Objective To evaluate the feasibility and safety of da Vinci robotic surgery for elderly patients with radical surgery of lung cancer. Methods We retrospectively analyzed the clinical data of 59 patients aged over 70 years who underwent radical surgery of lung cancer in our hospital between 2016 and 2019. These patients were divided into two groups including a da Vinci robot group and a single-utility port video-assisted thoracoscopic surgery (VATS) group according to the patients’ selection of the treatments. There were 32 patients with 20 males and 12 females aged 73.1±2.3 years in the da Vinci robot group and 27 patients with 16 males and 11 females aged 71.2±1.3 years in the VATS group. The clinical data of the two groups were compared. Results There was no statistical difference in surgery time between the two groups (t=–0.341, P=0.484). Compared with the VATS group, the da Vinci robot group had more number of lymph nodes dissected (t=1.635, P=0.015), less intraoperative blood loss (t=–2.569, P <0.001), less postoperative drainage amount within 3 days after surgery (t=–6.325, P=0.045), lower visual analogue scale (VAS) scores at postoperative 3rd day (t=–7.214, P=0.021). Conclusion The da Vinci robot system is safe and efficient in the treatment for elderly patients with radical surgery of lung cancer with less trauma.
RESUMO
Objective To investigate hemocoagulase hemostatic effect in lung cancer radical surgery and its effect on protease-activated receptor-1 (PAR-1 ).Methods 86 cases of pathologically confirmed lung cancer patients were randomly divided into control group and observation group,which controls were used etamsylate,observation group were used hemocoagulase,then to measure the amount of bleeding,clotting system-related factors before and after surgery,using ELISA assay to detect P-selectin,flow cytometry to measure platelet PAR-1 ,Western Blot to determine lung tissue expression of PAR-1,and the resulting data were statistically analyzed. Results The blood loss of observation group during surgery and postoperative 2d compared with the control group,had a significant difference (P<0.05 );flow cytometry results showed that,PAR-1-positive rate and P-selectin in different time periods in observation group were no statistically significant,while had a statistically significant compared with control group(P<0.05 );Western Blot detected hemocoagulase of lung tissue in patients with PAR-1 had no obvious effect,while control group had significant difference (P<0.05).Conclusion Venin hemocoagulase in lung cancer radical surgery can reduce the amount of bleeding,and be more stable for the role of the coagulation system,as well as less effect on the P-selectin and PAR-1.The results suggest that vonin hemocoagulase might not make patients with systemic hypercoagulable state in patients undergoing radical process with lung cancer,in other words it might not lead to PAR-1 highly expression to cause tumor cell metastasis.
