  • Comparison of Surgical Trauma Between Videoassisted Thoracoscopic Surgery and Conventional Thoracotomy

    Objective To compare the surgical trauma between videoassisted thoracoscopic surgery(VATS) and conventional thoracotomy, and to investigate the possible minimally invasive mechanism. Methods Seventyseven patients who had undergone consecutive operations from April 2005 to January 2006 were chosen from cardiothoracic surgery department of Fujian Provincial Hospital. Twentytwo cases had spontaneous pneumothorax diagnosed by chest X-ray examination, twentynine had patent ductus arteriosus diagnosed by color echocardiography, and twentysix had congenital atrial septal defect. According to lesions and operative methods, the patients were divided into two groups: conventional thoracotomy group(CTH group) and videoassisted thoracoscopic surgery group(VATS group). The concentrations of serum C-reactive protein(CRP),interleukin6 (IL-6),interleukin-8(IL-8) and tumor necrosis factor-α(TNF-α) were selected as indexes to measure surgical trauma. ARRAY360 specific protein and pharmaceutical analysis system were used to determine CRP automaticly at the day before operation and on the 1st, 2nd and 3rd day after operation. Radioimmunoassay was used to measure the concentrations of IL-6,IL-8 and TNF-α. Clinical indexes such as operative time, cardiopulmonary bypass (CPB) time, intraoperative blood lost, postoperative analgesic time and hospitalization time were analyzed and compared. Results Under the condition that patients had the same diseases, there was no statistical significance in preoperative concentrations of serum CRP,IL-6,IL-8 and TNFα between VATS group and CTH group(P=0.067, 0.062, 0.053,0.064). The concentrations of serum CRP(P=0.045,0.043,0.044), IL-6(P=0.042,0.032,0.039), IL-8(P=0.046,0.045,0.048) and TNF-α(P=0.041,0.043,0.043) on the 1st, 2nd and 3rd day after operation were significantly lower in VATS group than that in CTH group (Plt;0.05). Compared with CTH group, there were less blood lost(P=0.032), shorter postoperative analgesic time and hospitalization time(P=0.041) in VATS group. There was no statistical significance in CPB time between two groups. However, hospitalization time varied with different diseases. Conclusion Compared with conventional thoracotomy,videoassisted thoracoscopic surgery has less surgical trauma, less intraoperative blood lost, shorter postoperative analgesic time, and can make patients recover rapidly. So it is worth spreading.

  • Preoperative peripheral blood CD4/CD8 ratio in predicting the prognosis of patients with coronary atherosclerotic heart disease after off-pump coronary artery bypass grafting

    ObjectiveTo investigate the role of preoperative peripheral blood CD4/CD8 ratio in predicting the prognosis of patients with coronary atherosclerotic heart disease (CAD) after off-pump coronary artery bypass grafting (OPCABG).MethodsA total of 118 patients with CAD who underwent OPCABG in our hospital from September 2016 to April 2017 were included in the study, including 82 males and 36 females aged 62.74±4.50 years. The primary end point was the incidence of major adverse cardiovascular events (MACE). Patients were divided into a high CD4/CD8 group (≥1.40, 62 patients) and a low CD4/CD8 group (<1.40, 56 patients) according to the results of flow cytometry. The correlation between CD4/CD8 ratio and prognosis of patients after OPCABG and the value of CD4/CD8 ratio for predicting postoperative MACE were evaluated.ResultsMedian duration of follow-up was 23.25 (20.91, 24.70) months, during which 21 patients (17.80%) experienced MACE and 4 patients (3.39%) were lost to follow-up. Kaplan-Meier analysis revealed that high CD4/CD8 group had a significantly higher MACE rate than the low CD4/CD8 group did (log-rank χ2=5.797, P=0.02). The results of adjusted Cox proportional hazards model showed that CD4/CD8 ratio (HR=3.103, 95%CI 1.557-6.187, P<0.01) was an independent risk factor of MACE in patients with CAD after OPCABG. The receiver operating characteristic curve showed that area under curve was 0.778 (95%CI 0.661-0.894, P<0.01), the optimal cut off value was 2.24, the sensitivity was 57.1%, and the specificity was 87.6%.ConclusionPreoperative peripheral blood CD4/CD8 ratio is an independent predictor of MACE after OPCABG in patients with CAD.
