Small pulmonary lesions can be difficult to localize during video-assisted thoracoscopic surgery. Electromagnetic navigation bronchoscopy (ENB) dye marking of the lesion, particularly when guided by cone beam computed tomography in the hybrid operating room (HOR), is an emerging approach. However, issues with confirmation of dye injection and intraoperative visualization of the colored dye can be unpredictable and challenging. To address these uncertainties, we present our technique of ENB dye marking localization of lung nodule using the triple-contrast dye method in the HOR.
Background
For patients with stage IA non-small cell lung cancer (NSCLC) with tumor size ≤ 2 cm, the prognostic significance of the number of removed lymph nodes (NLNs) through different surgical methods remains unclear. To determine the association of NLNs with cancer-specific survival (CSS) and overall survival (OS) in patients with stage IA NSCLC with tumor size ≤ 2 cm who underwent different lung surgeries.
Methods
We retrospectively enrolled 7293 patients from the Surveillance, Epidemiology and End Results database. Median NLNs was used to classify the patients into two groups: group A with NLNs ≤ 5 and group B with NLNs > 5. Propensity score matching (PSM) was performed to decrease selection bias. Kaplan–Meier analysis and Cox regression analysis were performed to identify the association between NLNs and survival outcomes.
Results
Group B had better survival than group A in the unmatched cohort and matched cohort (all P < 0.05). Multivariable analyses revealed that the NLNs significantly affected CSS and OS of eligible cases in the unmatched cohort and matched cohort. Additionally, we found that the NLNs was a protective prognostic predictor of OS for patients who underwent wedge resection, segmental resection, or lobectomy.
Conclusion
The NLNs was a protective prognostic factor in NSCLC patients with tumor size ≤ 2 cm. We demonstrated that patients with > 5 NLNs in the cohort of wedge resection, segmental resection, or lobectomy exhibited a significantly better OS.
Background: The purpose of the study was to determine whether the active cycle of breathing technique (ACBT) has an impact on postoperative pulmonary complication (PPC) after esophagectomy. Methods: In this prospective randomized trial, patients who were candidates for esophagectomy were randomized into groups, wherein they received either ACBT (n = 146) or conventional chest physiotherapy (control group, n = 145) on postoperative days (POD) 1-3. The primary outcome was PPC. The secondary outcomes included the incidence of anastomotic leakage (AL), efficacy of airway clearance, and postoperative hospital length of stay (LOS). Results: After esophagectomy, the PPC rate was significantly lower in the ACBT group (15.2%) than in the control group (31.0%) (p = 0.001). The incidences of AL were 5.5% and 12.4% in the ACBT and control groups, respectively (p = 0.042). Mean hospital LOS was 12.3 days for the ACBT group and 16.8 days for the control group (p = 0.008). ACBT significantly increased the mean sputum wet weight (g) on POD 1-3 when compared with conventional therapy (POD 1 9.08 vs. 6.47, POD 2 16.86 vs. 10.92, POD 3 24.65 vs. 13.52, all p < 0.001). Multivariable analysis revealed that ACBT decreased the rates of PPC (odds ratio [OR] 0.403, p = 0.003), AL (OR 0.379, p = 0.038),arrhythmia (OR 0.397, p = 0.028), and bronchoscopy aspiration (OR 0.362, p = 0.016). Conclusion: ACBT is an effective airway clearance technique that significantly reduces the incidence of PPC after esophagectomy. ACBT could also significantly reduce both AL and LOS.
