Objective To evaluate the clinical effectiveness of ERCP/S+LC and LC+LCBDE in cholecystolithiasis and choledocholithiasis. Methods A fully recursive literature search was conducted in MEDLINE, EMbase, Cochrane Central Register of Controlled Trials in any language. By using a defined search strategy, both the randomized controlled trials (RCTs) and controlled clinical trials on comparing ERCP/ S+LC with LC+LCBDE in cholecystolithiasis and choledocholithiasis were identified. Data were extracted and evaluated by two reviewers independently. The quality of the included trials was evaluated. Meta-analyses were conducted using the Cochrane Collaboration’s RevMan 5.0.2 software. Results Fourteen controlled clinical trials (1 544 patients) were included. The results of meta-analyses showed that: a) There were no significant difference in the stone clearance rate between the two groups (RR=0.96, 95%CI 0.92 to 1.01, P=0.14); b) There were no significant difference in the residual stone rate between the two groups (OR=1.05, 95%CI 0.65 to 1.72, P=0.83); c) There were no significant difference in the complications morbidity between the two groups (OR=1.12, 95%CI 0.85 to 1.55, P=0.48); d) There were no significant difference in the mortality during follow-up visit between the two groups (RD= 0.00, 95%CI –0.03 to 0.03, P=0.84); e) The length of hospital stay in the LC+LCBDE group was shorter than that of the ERCP/S+LC group with significant difference (WMD= 1.78, 95%CI 0.94 to 2.62, Plt;0.000 1); and f) The LC+LCBDE group was superior to the ERCP/S+LC group in the aspects of procedure time and total hospital charges. Conclusion Although there aren’t differences in the effectiveness and safety between the ERCP/S+LC group and the LC+LCBDE group, the latter is superior to the former in procedure time, length of hospital stay and total hospital charges. For the influencing factors of lower quality and astable statistical outcomes of the included studies, this conclusion has to be verified with more strictly designed large scale RCTs.
Objective To investigate the efficacy of low-dose inhaled nitric oxide (iNO) in the treatment of severe hypoxemia after Sun’s operation. Methods The clinical data of patients undergoing Sun’s operation for acute Type A aortic dissection in our hospital from January 2020 to June 2022 were retrospectively analyzed. Patients who received conventional treatment before November 2021 were enrolled as a control group. After November 2021, iNO was used in our hospital, and the patients who received iNO as an iNO group. The preoperative clinical baseline data, perioperative clinical data and oxygenation index were compared between the two groups. Results A total of 54 patients were included in the control group, including 45 males and 9 females, with an average age of 53.0±10.9 years. A total of 27 patients were included in the iNO group, including 21 males and 6 females, with an average age of 52.0±10.6 years. The preoperative body mass index of the two groups was greater than 25 kg/m2, white blood cell count, C-reactive protein were significantly higher than normal level, but there was no statistical difference between the groups (P＞0.05). There were no statistical differences in intraoperative data between the two groups (P＞0.05). The iNO group had significantly shorter duration of mechanical ventilation, postoperative ICU stay, and postoperative hospital stay than the control group (P<0.001). After 12 h of iNO treatment, hypoxic condition improved obviously, oxygenation indices in 12 h, 24 h, 36 h,48 h, 60 h and 72 h in the iNO group were significantly higher than those in the control group (P<0.05). Conclusion The treatment of severe hypoxemia after Sun’s surgery with low-dose of iNO is safe and effective, can significantly improve oxygenation function, and has significant advantages in shortening ventilator use time, postoperative ICU stay and postoperative hospital stay, but it is not significant in changing postoperative mortality.
ObjectiveTo study the correlation between Periostin, interleukin-33 (IL-33), and chronic cough after thoracoscopic lobectomy in patients with coronary artery bypass grafting (CABG) combined with lung cancer. Methods A total of 102 lung cancer patients at Tianjin Chest Hospital from January 2022 to January 2024 were prospectively enrolled, and they were divided into a chronic cough group and a non chronic cough group based on whether chronic cough occurred after surgery. Serum levels of Periostin and IL-33 were measured on the 1st, 7th, and 14th days post-lobectomy. The Pearson method was employed to analyze the correlation between Periostin and IL-33 levels and the severity of cough. Univariate and multivariate logistic regression analyses were conducted to identify factors influencing the occurrence of chronic cough. Additionally, ROC curve analysis was utilized to assess the potential value of serum Periostin and IL-33 levels in predicting postoperative chronic cough. Results In patients with chronic cough, the peripheral blood Periostin and IL-33 levels measured on days 7 and 14 were significantly higher than those in patients with non-chronic cough, and the interactions between the two groups and at different time points were significant (P<0.001). The degree of cough was positively correlated with the levels of Periostin and IL-33 on days 7 and 14 (P<0.05), but had no significant correlation with the levels on day 1 (P>0.05). In patients with lung cancer, after thoracoscopic lobectomy, Periostin [OR=1.619, 95%CI (1.295, 2.025)] and IL-33 [OR=1.831, 95%CI (1.216, 2.758)] on day 7 and Periostin on day 14 [OR=1.952, 95%CI (1.306, 2.918)] and IL-33 [OR=1.742, 95%CI (1.166, 2.603)] were identified as risk factors for chronic cough. ROC curve analysis showed that the sensitivity of Periostin on day 7 was 69.05%, the specificity was 71.67%, and the AUC was 0.756 [95%CI (0.616, 0.893)]. The sensitivity of Periostin on day 14 increased to 71.43% and the specificity was 76.67%, AUC was 0.762 [95%CI (0.633, 0.898)]. At the same time, the critical value of IL-33 on day 7 was 45.03 pg/mL, the sensitivity and specificity were both 83.33%, the AUC was 0.884 [95%CI (0.789, 0.980)], and the critical value of IL-33 on day 14 was 56.01 pg/mL, the sensitivity was 85.71%, the specificity was 80.00%, and the AUC was 0.899 [95%CI (0.799, 0.999)]. Further regression analysis showed that the sensitivity was 95.24%, the specificity was 95.00%, and the AUC reached 0.993 [95%CI (0.979, 1.000)]. Conclusion Periostin and IL-33 levels, measured at various time points, are abnormally elevated following thoracoscopic lobectomy in patients with combined CABG and lung cancer. These levels significantly correlate with cough severity. Given their predictive potential for chronic cough, these markers are deemed valuable biomarkers.
ObjectiveTo investigate the relationship between the changes in preoperative serum creatinine (Cr), myoglobin (Mb), alanine aminotransferase (ALT) and postoperative fibrinogen (Fib), hemoglobin (Hb) expression levels with postoperative hypoxemia in patients with aortic dissection aneurysm (ADA). Based on this, a predictive model is constructed. Additionally, the study explores the role of transpulmonary pressure-guided positive end expiratory pressure (PEEP) in improving postoperative hypoxemia. MethodsA retrospective analysis was conducted on the clinical data of ADA patients admitted to Tianjin University’s Thoracic Hospital from April 2021 to August 2023. Patients were divided into a hypoxemia group [partial pressure of oxygen/fraction of inspiration oxygen (PaO2/FiO2) ≤200 mm Hg] and a non-hypoxemia group (PaO2/FiO2 >200 mm Hg) based on whether they developed postoperative hypoxemia. Univariate and multivariate regression analyses were used to identify risk factors for postoperative hypoxemia in ADA patients and to construct a predictive model for postoperative hypoxemia. The receiver operating characteristic (ROC) curve was plotted, and the Hosmer-Lemeshow goodness-of-fit test was used to evaluate the predictive value of the model. Furthermore, the impact of different ventilation modes on the improvement of postoperative hypoxemia was analyzed. From April 2021 to August 2023, 16 ADA patients with postoperative hypoxemia who received conventional mechanical ventilation were included in the control group. From September 2023 to December 2024, 28 ADA patients with postoperative hypoxemia who received transpulmonary pressure-guided PEEP were included in the experimental group. ICU stay duration, mechanical ventilation duration, hospital mortality rate, and respiratory and circulatory parameters were analyzed to evaluate the effect of transpulmonary pressure-guided PEEP on patients with postoperative hypoxemia after acute aortic dissection. ResultsA total of 98 ADA patients were included, of which 79 (80.61%) were males and 19 (19.39%) were females. Their ages ranged from 32 to 79 years, with an average age of (49.4±11.2) years. Sixteen (16.3%) patients developed postoperative hypoxemia. Body mass index (BMI), smoking history, cardiopulmonary bypass (CPB) duration, preoperative serum Cr, Mb, ALT, postoperative Fib, and postoperative C-reactive protein showed a certain correlation with postoperative hypoxemia in ADA patients (P<0.05). There was no statistically significant difference in other baseline data between the two groups (P>0.05). Logistic regression analysis results indicated that BMI [OR=1.613, 95%CI (1.260, 2.065)] and preoperative Mb [OR=2.The results showed that preoperative BMI [OR=1.324, 95%CI (1.080, 2.065)], preoperative ALT [OR=1.012, 95%CI (1.000, 1.024)], preoperative Cr [OR=1.752, 95%CI (1.045, 2.940)], postoperative Fib [OR=1.165, 95%CI (1.080, 1.258)] and intraoperative CPB time [OR=1.433, 95%CI (1.017, 2.020)] were influencing factors of postoperative hypoxemia in ADA patients (P<0.05). Based on this, a prediction model for postoperative hypoxemia in ADA patients was established, with the prediction equation being P=1−1/(1+econstant + 0.67×BMI+1.14×CPB+0.52×Cr+0.73×Mb+ 0.44×ALT+1.12×Fib. The area under the curve corresponding to the optimal critical point was 0.837 [95%CI (0.799, 0.875)], with a sensitivity of 87.5% and a specificity of 79.3%. The Hosmer-Lemeshow goodness of fit test showed P=0.536. Before treatment, there were no statistically significant differences in respiratory and circulatory parameters between the conventional group and the experimental group (P>0.05). After treatment, the levels of PEEP, PaO2/FiO2, end-expiratory esophageal pressure, and end-inspiratory transpulmonary pressure in the experimental group were higher than those in the control group, with statistically significant differences (P<0.05). The duration of mechanical ventilation and ICU stay in the experimental group were shorter than those in the control group, with statistical differences (P<0.05), while there was no statistical difference in mortality between the two groups (P=0.626). ConclusionThe hypoxia prediction model based on preoperative Cr, Mb, ALT and postoperative Fib levels, combined with transpulmonary pressure-guided PEEP optimization, provides a scientific basis for the precise management of postoperative hypoxemia in ADA. This approach not only improves the predictive ability of hypoxemia risk but also significantly improves the postoperative oxygenation status of patients through personalized mechanical ventilation strategies, providing new insights into the management of postoperative complications.
