Objective:To investigate risk factors of arrhythmia in elderly patients with early lung cancer after thoracoscopic pulmonary resection to construct a prediction model.Methods:Two hundreds and twenty elderly patients with early lung cancer after thoracoscopic pulmonary resection were retrospectively chosen in the period from January 2017 to January 2023 in Guang'an People's Hospital of Sichuan Province. The occurrence of arrhythmia was calculated, and the clinical data of patients with arrhythmia and those without arrhythmia were compared. Logistic regression was employeed to analyze the independent influencing factors of arrhythmia in elderly patients with early lung cancer after thoracoscopic pneumonectomy. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic performance of regression model on arrhythmia after thoracoscopic pneumonectomy in elderly patients with early lung cancer.Results:Forty-one of 220 (18.64%) elderly patients with early lung cancer treated by thoracoscopic pneumonectomy had arrhythmia. There were statistically significant differences between patients with arrhythmia and patients without arrhythmia in age ( χ2=17.76, P<0.001), combined with essential hypertension ( χ2=21.06, P<0.001), forced expiratory volume in one second as a percentage of predicted value (FEV 1%) ( χ2=17.88, P<0.001), left atrium anterior-and-posterior diameter ( χ2=37.82, P<0.001), operation type ( χ2=27.09, P<0.001) and postoperative constipation ( χ2=18.25, P<0.001). The results of multivariate analysis showed that age>75 years old ( OR=22.17, 95% CI: 3.78-130.11, P=0.001), combined with essential hypertension ( OR=26.55, 95% CI: 3.99-176.95, P=0.001), FEV 1%≤70% ( OR=6.20, 95% CI: 1.37-28.11, P=0.018), left atrium anterior-and-posterior diameter>40 mm ( OR=10.84, 95% CI: 2.24-52.45, P=0.003), thoracoscopic lobectomy ( OR=7.07, 95% CI: 1.62-30.80, P=0.009), and postoperative constipation ( OR=79.97, 95% CI: 11.87-538.83, P<0.001) were all independent risk factors for arrhythmia after thoracoscopic pulmonary resection in elderly patients with early lung cancer. A prediction model was established for statistically significant indicators in multivariate analysis, ln ( P/1- P) =-7.89+3.10×age+3.28×combined with essential hypertension+1.82×FEV 1%+2.38×left atrium anterior-and-posterior diameter+1.96×operation type+4.38×postoperative constipation ( P was the prediction probability of P value in regression model). ROC curve analysis showed that the area under the curve (AUC) of predict arrhythmia after thoracoscopic pulmonary resection in elderly patients with early lung cancer were 0.64, 0.71, 0.68, 0.74, 0.76, 0.87 and 0.98, respectively. The Yoden index was 27.29%, 42.28%, 34.92%, 47.42%, 73.63%, 50.97% and 91.97%, respectively. Conclusion:Age>75 years old, combined with essential hypertension, FEV 1%≤70%, left atrium anterior-and-posterior diameter>40 mm, thoracoscopic lobectomy and postoperative constipation are all independent risk factors for arrhythmia after thoracoscopic pulmonary resection in elderly patients with early lung cancer. Nomogram model based on the above risk factors has high efficacy in predicting arrhythmia occurance after thoracoscopic pulmonary resection.
RÉSUMÉ
Objective:To systematically compare the prognosis in non-compressible torso hemorrhage（NCTH）treated by resuscitative endovascular balloon occlusion of the aorta（REBOA）and resuscitation thoracotomy（RT）.Methods:Data were searched form MEDLINE, EMBASE, PubMed, WanFang, CNKI and VIP databases to collect studies on the prognosis of patients with NCTH undergone REBOA and RT from inception to December 2020. Two reviewers independently screened studies according to the inclusion and exclusion criteria, extracted data and evaluated the quality of the included studies. The Meta-analysis was performed using Revman 5.3. The patients were divided into REBOA group and RT group according to the different surgical treatment methods on admission, and the prognosis of each group was evaluated. The difference of mortality rate, reoperation rate of laparotomy after operation, reoperation rate of embolization after operation and mortality rate in different operating room area were compared between the two groups. Publication bias was assessed using the Egger test.Results:A total of 2 prospective studies and 4 retrospective studies involving 2, 588 subjects were included. There were 1, 591 patients in REBOA group and 997 patients in RT group. Significant differences were observed in the mortality rate（ I2=68%, OR=0.33, 95% CI 0.26-0.42, P<0.01）, reoperation rate of laparotomy after operation（ I2=76%, OR=1.41, 95% CI 1.11-1.77, P<0.01）and reoperation rate of embolization after operation（ I2=84%, OR=0.76, 95% CI 0.59-0.99, P<0.05）between REBOA group and RT group. Subgroup analysis showed that the mortality rate in the ICU were not statistically different between the two groups（ I2=83%, OR=0.69, 95% CI 0.45-1.05, P>0.05）, but the mortality rate in the emergency room was lower in REBOA group than that in RT group（ I2=94%, OR=0.52, 95% CI 0.38-0.70, P<0.01）. Egger test showed that publication bias had little effect on the results. Conclusions:For patients with NCTH, REBOA can reduce the mortality rate and reoperation rate of embolization after operation, but increase the reoperation rate of laparotomy after operation when compared with RT. In addition, the emergency room may be a more suitable operationg room area for REBOA.
