Each year, millions of pulmonary nodules are identified incidentally or through lung cancer screening, and many involve biopsy to distinguish cancer from benign processes. Both navigational bronchoscopy and computed tomography-guided transthoracic needle biopsy are commonly used in patients undergoing biopsies of peripheral pulmonary nodules, but the relative diagnostic accuracy of these two approaches is unclear. In this multicenter, randomized, parallel-group, noninferiority trial, we assigned patients with an intermediate-risk or high-risk peripheral pulmonary nodule measuring 10 to 30 mm in diameter to undergo navigational bronchoscopy or transthoracic needle biopsy at seven centers across the United States. The primary outcome was diagnostic accuracy, which was defined as the percentage of patients with biopsies that showed a specific diagnosis (cancer or a specific benign condition) that was confirmed to be accurate through 12 months of clinical follow-up (nonferiority margin, 10 percentage points). Secondary outcomes included procedural complications such as the occurrence of pneumothorax. Among the 234 patients included in the primary-outcome analysis (5 of whom were lost to follow-up), biopsy resulted in a specific diagnosis that was confirmed to be accurate through month 12 in 94 of 119 patients (79.0%) in the navigational bronchoscopy group and in 81 of 110 patients (73.6%) in the transthoracic needle biopsy group (absolute difference, 5.4 percentage points; 95% confidence interval, -6.5 to 17.2; P = 0.003 for noninferiority; P = 0.17 for superiority). Pneumothorax occurred in 4 of 121 patients (3.3%) in the navigational bronchoscopy group and in 32 of 113 patients (28.3%) in the transthoracic needle biopsy group and led to the placement of a chest tube, hospital admission, or both in 1 patient (0.8%) and 13 patients (11.5%), respectively. The diagnostic accuracy of navigational bronchoscopy was noninferior to that of transthoracic needle biopsy among patients with peripheral pulmonary nodules measuring 10 to 30 mm.

PurposeTo assess the efficacy of the tract embolization technique using gelatin sponge slurry after CT-guided lung biopsy to reduce pneumothorax and chest tube placement rates.Materials and MethodsWe retrospectively compared 231 CT-guided lung biopsies performed with the tract embolization technique using gelatin sponge slurry (treated group) with 213 biopsies performed without embolization (control group). All procedures were performed at our institution between January 2014 and September 2018 by one of three experienced interventional radiologists using a 19-gauge coaxial needle. Multivariate analysis was performed between groups for risk factors for pneumothorax and chest tube placement, including patient demographics and lesion characteristics.ResultsWhen comparing the two groups, there was no significant difference concerning age, gender, emphysema, lesion size, lesion location, lesion morphology, needle tract depth and biopsy-side down patient positioning. Compared to the control group, patients with gelatin sponge slurry tract embolization had statistically lower rates of pneumothorax (10% vs. 25.8%; p < 0.0001) and chest tube placement (3.5% vs. 12.2%; p = 0.0005). Using multiple logistic regression analysis, the only variable that had an influence on the pneumothorax rate was the group (OR 0.32, 95% CI 0.18–0.56, p < 0.0001), and the variables that had an influence on the chest tube insertion rates were the group (OR 0.21, 95% CI 0.08–0.51, p = 0.0006) and presence of emphysema (OR 3.50, 95% CI 1.53–8.03, p = 0.0031).ConclusionsTract embolization technique using gelatin sponge slurry after percutaneous CT-guided lung biopsy significantly reduces pneumothorax and chest tube placement rates.Level of EvidenceLevel 3a.

Background The optimal tube size for managing traumatic hemothorax, pneumothorax, or hemopneumothorax remains debated. While large-bore chest tubes (LCTs—≥ 28 Ch) are traditionally favored, emerging evidence suggests that small-caliber tubes (SCTs—≤ 14 Ch), such as pigtail catheters and small straight tubes, may offer similar efficacy with fewer complications. This study aimed to evaluate the comparative effectiveness and safety of SCTs versus LCTs from Randomized Controlled Trials (RCTs) in adult trauma patients and to assess the conclusiveness of the current evidence using trial sequential analysis (TSA). Methods The study was conducted according to the Cochrane recommendations, searching the PubMed, Scopus, and EMBASE datasets up to 25th March 2025 without language restrictions (PROSPERO ID: CRD420251023165). The primary outcome was treatment failure; secondary outcomes included insertion-related complications, duration of drainage, and length of hospital stay. Random effects models based on restricted maximum likelihood and Hartung-Knapp correction were developed. Sensitivity analysis was conducted to detect sources of heterogeneity. The risk of bias was assessed using the Cochrane RoB 2 tool. TSA was used to evaluate the risk of random error and to determine whether the required information size (RIS) had been reached. Results Four RCTs ( n  = 676 patients) were included. Pooled analysis showed no significant difference in failure rates between SCTs and LCTs (RR 0.95, 95% CI 0.66–1.35, I 2  = 0%). No significant differences were observed in complication rates or hospital stay. Duration of tube placement was significantly shorter in the SCT group (MD − 0.49 days, p  = 0.02). TSA indicated that the cumulative evidence was underpowered, achieving only 22% of the RIS (3110 patients). The Z-curve did not cross thresholds for benefit, harm, or futility. Conclusion SCTs appear to be as effective and safe as LCTs for selected trauma patients with uncomplicated thoracic injuries. However, due to limited sample size and heterogeneity across trials, current evidence is inconclusive. Larger, high-quality RCTs are warranted to confirm these findings and guide clinical practice.

INTRODUCTION:Hepatic hydrothorax (HH) significantly contributes to morbidity in decompensated cirrhosis. Intercostal chest tube (ICT) insertion is discouraged in HH management. We examined trends in ICT use and impact on outcomes in hospitalized HH patients.METHODS:A retrospective cohort study (October 2015-December 2019) was conducted using the National Inpatient Sample to identify HH hospitalizations among patients with decompensated cirrhosis. Propensity score matching compared patients who received ICT with those who did not. Outcomes included in-hospital mortality (IHM), length of stay (LOS), total charges (TC), and complications.RESULTS:Among 127,627 cirrhosis hospitalizations, 7,843 (6.2%) had HH. Compared with those without HH, these patients had longer LOS, higher TC, and more acute kidney injury and sepsis (P < 0.001). HH was not associated with increased IHM, but ICT and spontaneous bacterial empyema were, each conferring ∼1.5-fold higher odds. ICT was used in 1,312 HH cases (16.7%), with increasing use over time (P = 0.037). In a matched cohort of HH hospitalizations (1,277 with ICT; 2,554 without), ICT use was linked to higher IHM (11.6% vs 8.5%), longer LOS (14.6 vs 8.7 days), and greater TC ($196,000 vs $112,000). Complications were more frequent with ICT: acute kidney injury (45% vs 39%), sepsis (18% vs 10%), and spontaneous bacterial empyema (12.5% vs 2%) (P < 0.001). ICT use was associated with 44% higher odds of IHM, OR (95% confidence intervals): 1.44 (1.15-1.81).DISCUSSION:HH occurs in 6.2% of cirrhosis hospitalizations, with 1 of 6 receiving ICT. ICT use is increasing despite poorer outcomes and greater resource utilization. Studies targeted toward better patient selection and provider education are needed to mitigate ICT use in HH.

Objectives Diagnostic accuracy of artificial intelligence (AI) pneumothorax (PTX) detection in chest radiographs (CXR) is limited by the noisy annotation quality of public training data and confounding thoracic tubes (TT). We hypothesize that in-image annotations of the dehiscent visceral pleura for algorithm training boosts algorithm’s performance and suppresses confounders. Methods Our single-center evaluation cohort of 3062 supine CXRs includes 760 PTX-positive cases with radiological annotations of PTX size and inserted TTs. Three step-by-step improved algorithms (differing in algorithm architecture, training data from public datasets/clinical sites, and in-image annotations included in algorithm training) were characterized by area under the receiver operating characteristics (AUROC) in detailed subgroup analyses and referenced to the well-established “CheXNet” algorithm. Results Performances of established algorithms exclusively trained on publicly available data without in-image annotations are limited to AUROCs of 0.778 and strongly biased towards TTs that can completely eliminate algorithm’s discriminative power in individual subgroups. Contrarily, our final “algorithm 2” which was trained on a lower number of images but additionally with in-image annotations of the dehiscent pleura achieved an overall AUROC of 0.877 for unilateral PTX detection with a significantly reduced TT-related confounding bias. Conclusions We demonstrated strong limitations of an established PTX-detecting AI algorithm that can be significantly reduced by designing an AI system capable of learning to both classify and localize PTX. Our results are aimed at drawing attention to the necessity of high-quality in-image localization in training data to reduce the risks of unintentionally biasing the training process of pathology-detecting AI algorithms. Key Points • Established pneumothorax-detecting artificial intelligence algorithms trained on public training data are strongly limited and biased by confounding thoracic tubes. • We used high-quality in-image annotated training data to effectively boost algorithm performance and suppress the impact of confounding thoracic tubes. • Based on our results, we hypothesize that even hidden confounders might be effectively addressed by in-image annotations of pathology-related image features.

Purpose Air leaks are common after pulmonary surgery. Prolonged air leaks (PALs) may persist through discharge and often are managed with one-way valve devices (OWD). We sought to determine the course and complications of patients discharged with OWDs, risk factors for complications, and to evaluate the utility of clamp trials before chest tube (CT) removal. Methods Single-institution, retrospective review of patients discharged with a OWD after pulmonary surgery between 2008 and 2022. Charts were examined for the presence of complications and CT duration. Differences in CT duration were compared by using the Wilcoxon rank-sum test. Result Sixty-four of 1917 (3.3%) pulmonary surgeries resulted in OWD use. Twelve of 64 (19%) patients discharged with a OWD suffered a complication. Nine of 64 (14%) had a CT-related readmission, and seven of 64 (11%) required PAL intervention. Patients sustaining a complication demonstrated longer CT durations before complication compared with duration in patients without complications, with median days of 13 [IQR 6–21] vs. 7 [IQR 6–12], p = 0.04). Five (7.8%) OWD patients developed an empyema; only one (20%) occurred before a CT duration of 14 days. Sixteen of 64 (25%) patients underwent a clamp trial before CT removal. One of ten (10%) failed even with no air leak present, whereas one of six (17%) failed with a present/questionable air leak. Conclusions One-way valve device use has a substantial complication rate, and chest tube duration is a risk factor. In-hospital interventions might benefit patients with larger leaks that likely require prolonged OWD use. Because clamp trials occasionally fail, we contend that a clamp trial is the safest course before CT removal.

Intensive care unit (ICU) patients undergo several diagnostic and therapeutic procedures every day. The prevalence, intensity, and risk factors of pain related to these procedures are not well known. To assess self-reported procedural pain intensity versus baseline pain, examine pain intensity differences across procedures, and identify risk factors for procedural pain intensity. Prospective, cross-sectional, multicenter, multinational study of pain intensity associated with 12 procedures. Data were obtained from 3,851 patients who underwent 4,812 procedures in 192 ICUs in 28 countries. Pain intensity on a 0-10 numeric rating scale increased significantly from baseline pain during all procedures (P < 0.001). Chest tube removal, wound drain removal, and arterial line insertion were the three most painful procedures, with median pain scores of 5 (3-7), 4.5 (2-7), and 4 (2-6), respectively. By multivariate analysis, risk factors independently associated with greater procedural pain intensity were the specific procedure; opioid administration specifically for the procedure; preprocedural pain intensity; preprocedural pain distress; intensity of the worst pain on the same day, before the procedure; and procedure not performed by a nurse. A significant ICU effect was observed, with no visible effect of country because of its absorption by the ICU effect. Some of the risk factors became nonsignificant when each procedure was examined separately. Knowledge of risk factors for greater procedural pain intensity identified in this study may help clinicians select interventions that are needed to minimize procedural pain. Clinical trial registered with www.clinicaltrials.gov (NCT 01070082).

Background The aim of this meta-analysis and systematic review of published evidence was to optimize chest tube management for fast-track rehabilitation of lung cancer patients after video-assisted thoracic surgery (VATS). Methods The PubMed, Web of Science, and EMBASE databases were searched to identify all studies that addressed the issue of chest tube management after VATS for lung cancer. Finally, 35 articles were included for analysis, i.e., 29 randomized controlled trials and 6 clinical trials. Results After synthesis of the published evidence, the following protocol for chest tube drainage was formulated: (1) after VATS lung wedge resection, chest tube drainage can be omitted in selected cases; (2) normally, one 28Fr chest tube (or 19Fr Blake drain) is placed; (3) the use of a digital monitoring system is recommended; (4) in case of increasing pneumothorax or severe air leakage supported by digital recording system, the tube should be placed with active suction; and (5) the chest tube can be removed within 48 h postoperatively when air leakage is resolved and fluid drainage is <400 mL/day. Conclusions Further multicenter studies are warranted based on the variations of body sizes among different ethnicities.

Background and aim Removing the chest tube in cardiac patients after surgery is one of the worst experiences of hospitalization in the intensive care units. Various pharmacological and non-pharmacological methods are available to control pain in these patients. This study aimed to investigate the combined effect of reflexology massage and respiratory relaxation on pain following chest tube removal in cardiac surgery patients of Shahid Beheshti Hospital in Shiraz, Iran, in 2023. Methods This was a double-blind randomized clinical trial performed on 140 patients who underwent heart surgery and had a chest tube in Shiraz, Iran. The samples were randomly divided into four groups: 1- control group, 2- respiratory relaxation group, 3- foot reflex massage group, and 4- a combination of respiratory relaxation and reflexology massage. To collect data, two demographic questionnaires, and a visual analog scale were used. Results The participants of the four groups were not meaningfully different in terms of age, BMI, duration of surgical operation, gender, job, education, place of residency, number of chest tubes, history of operation ( P  = 0.99, 0.31, 0.06, 0.81, 0.97, 0.96, 0.17, 0.10, 0.89 respectively). The mean scores of pain intensity during chest tube removal, and 15 min after chest tube removal were not statistically different among the four groups of study ( P  = 0.15, 0.54 respectively); However, just after chest tube removal, the mean scores of pain intensity differed meaningfully among four groups ( P  = 0.008). Conclusion The results showed that reflexology massage and respiratory relaxation both reduce pain immediately after chest tube removal in heart surgery patients. Also, the combination of these two techniques was more effective in reducing patients’ average pain.

Background Pain caused by chest tube placed after uniportal video-assisted thoracoscopic surgery (UVATS) is often neglected. Ropivacaine can be used to alleviate pain related to the chest tube, but the current lowest effective concentration of ropivacaine remains unclear. Methods To investigate the analgesic effect of administering two different concentrations of ropivacaine into the pleural cavity via pleural drainage tube bypass after UVATS. Ninety patients were randomly divided into three groups: Control group (PCIA only), Low-dose group (PCIA combined with intrathoracic infusion of 200 ml 0.25% ropivacaine), Medium-dose group (PCIA combined with intrathoracic infusion of 200 ml 0.5% ropivacaine). The analysis included Visual Analogue Scale (VAS) scores for chest tube-related pain and surgical incision pain at 6 h, 12 h, 24 h, and 48 h post-operation for each group. Compare incidence of adverse reactions (respiratory depression, hypotension, nausea/vomiting, arrhythmia, dizziness) within 48 h. Results Compared to the control group, both 0.25% and 0.50% ropivacaine effectively reduced chest tube-related pain ( P  < 0.001) and surgical incision pain ( P  < 0.001) at 6 h, 12 h, 24 h, and 48 h postoperatively. However, no significant differences were observed between the two concentrations of ropivacaine in alleviating rest and cough pain related to the chest tube ( P  > 0.05) or surgical incision ( P  > 0.05) within 48 h postoperatively. Adverse reaction rates were similar among groups within 48 h postoperatively ( P  = 0.383). Conclusion The analgesic effect of ropivacaine infusion with concentrations of 0.25% and 0.50% administered via intrathoracic pumps for chest tube-related pain after UVATS showed no significant difference, but both were superior to the sole use of PCIA.
