RESUMEN
BACKGROUND: An increased incidence of pneumomediastinum has been observed among patients hospitalized with coronavirus disease 2019 (COVID-19) pneumonia. The study aimed to identify risk factors for COVID-19-associated pneumomediastinum and investigate the impact of pneumomediastinum on clinical outcomes. METHODS: In this multicentre retrospective case-control study, we included consecutive patients with COVID-19 pneumonia and pneumomediastinum hospitalized from March 2020 to July 2020 at ten centres; then, we identified a similarly sized control group of consecutive patients hospitalized with COVID-19 pneumonia and respiratory failure who did not develop pneumomediastinum during the same period. Clinical, laboratory, and radiological characteristics, as well as respiratory support and outcomes, were collected and compared between the two groups. Risk factors of pneumomediastinum were assessed by multivariable logistic analysis. RESULTS: Overall 139 patients with pneumomediastinum and 153 without pneumomediastinum were analysed. Lung involvement ≥75 %, consolidations, body mass index (BMI) < 22 kg/m2, C-reactive protein (CRP) > 150 mg/L, D-dimer >3000 ng/mL FEUs, and smoking exposure >20 pack-year were all independently correlated with the occurrence of pneumomediastinum. Patients with pneumomediastinum had a longer hospital stay (mean ± SD 31.2 ± 20.2 days vs 19.6 ± 14.2, p < 0.001), higher intubation rate (73/139, 52.5 % vs 27/153, 17.6 %, p < 0.001), and in-hospital mortality (68/139, 48.9 % vs 36/153, 23.5 %, p < 0.001) compared to controls. CONCLUSIONS: Extensive lung parenchyma involvement, consolidations, low BMI, high inflammatory markers, and tobacco exposure are associated with a greater risk of pneumomediastinum in COVID-19 pneumonia. This complication significantly worsens the outcomes.

BACKGROUND: Completion lobectomy (CL) following a prior resection in the same lobe may be complicated by severe pleural or hilar adhesions. The role of uniportal video-assisted thoracoscopic surgery (U-VATS) has never been evaluated in this setting. METHODS: Data were collected from two Italian centers. Between 2015 and 2022, 122 patients (60 men and 62 women, median age 67.7 ± 8.913) underwent U-VATS CL at least 4 weeks after previous lung surgery. RESULTS: Twenty-eight (22.9%) patients were affected by chronic obstructive pulmonary disease (COPD) and twenty-five (20.4%) were active smokers. Among the cohort, the initial surgery was performed using U-VATS in 103 (84.4%) patients, triportal-VATS in 8 (6.6%), and thoracotomy in 11 (9.0%). Anatomical segmentectomy was the initial surgery in 46 (37.7%) patients, while hilar lymphadenectomy was performed in 16 (13.1%) cases. CL was performed on 110 (90.2%) patients, segmentectomy on 10 (8.2%), and completion pneumonectomy on 2 (1.6%). Upon reoperation, moderate pleural adhesions were observed in 38 (31.1%) patients, with 2 (1.6%) exhibiting strong adhesions. Moderate hilar adhesions were found in 18 (14.8%) patients and strong adhesions in 11 (9.0%). The median operative time was 203.93 ± 74.4 min. In four (3.3%) patients, PA taping was performed. One patient experienced intraoperative bleeding that did not require conversion to thoracotomy. Conversion to thoracotomy was necessary in three (2.5%) patients. The median postoperative drainage stay and postoperative hospital stay were 5.67 ± 4.44 and 5.52 ± 2.66 days, respectively. Postoperative complications occurred in 34 (27.9%) patients. Thirty-day mortality was null. Histology was the only factor found to negatively influence intraoperative outcomes (p = 0.000). Factors identified as negatively impacting postoperative outcomes at univariate analyses were male sex (p = 0.003), age > 60 years (p = 0.003), COPD (p = 0.014), previous thoracotomy (p = 0.000), previous S2 segmentectomy (p = 0.001), previous S8 segmentectomy (p = 0.008), and interval between operations > 5 weeks (p= 0.005). In multivariate analysis, only COPD confirmed its role as an independent risk factor for postoperative complications (HR: 5.12, 95% CI (1.07-24.50), p = 0.04). CONCLUSIONS: U-VATS CL seems feasible and safe after wedge resection and anatomical segmentectomy.
RESUMEN
OBJECTIVES: The aim of this study is to evaluate if the efficacy and safety of chest tube placement are influenced by the level of intercostal space insertion (uniportal VATS vs. biportal VATS) or by the type of drain employed (standard vs. smart coaxial drain). METHODS: Data on patients who underwent either uniportal or biportal VATS upper lobectomies with lymphadenectomy were prospectively collected in three European centers. The uniportal VATS group with a 28 Fr standard chest tube (U-VATS standard) was compared with the uniportal VATS group with a 28 Fr smart drain (U-VATS smart), and U-VATS smart was also compared with biportal VATS with a 28 Fr smart drain inserted in the VIII intercostal space (Bi-VATS smart). RESULTS: When comparing the U-VATS standard group with the U-VATS smart, a higher fluid output was recorded in the U-VATS smart (p: 0.004) in the III post-operative day (p.o.) and overall (p: 0.027), with a lower 90-day re-admission in the U-VATS smart (p: 0.04). The Bi-VATS smart group compared to U-VATS smart showed a higher fluid output in the I p.o. (p < 0.001), with no difference in total fluid amount or hospitalization. The Bi-VATS smart recorded a lower incidence (p < 0.001) of residual pleural space or effusion (p: 0.004) at chest X-rays prior to drain removal but a higher level of pain and chronic intercostal neuralgia (p: 0.03). CONCLUSIONS: Chest tube insertion through the same incision space in uniportal VATS seems to be safe and effective. Smart drains can improve the fluid output in uniportal VATS, as if the drainage were inserted in a lower space (i.e., biportal VATS), but with less discomfort.
RESUMEN
BACKGROUND: To evaluate the analgesic efficacy of continuous erector spinae plane block(c-ESPB) and serratus anterior plane block(c-SAPB) versus the intercostal nerve block (ICNB) in Uniportal-VATS in terms of pain control, drug consumption, and complications. METHODS: Ninety-three consecutive patients, undergone one of the three peripheral nerve blocks after Uniportal-VATS, were prospectively enrolled. A 1:1 propensity score matching was used to minimize bias. RESULTS: C-ESPB and c-SAPB groups had no difference in morphine request upon awakening compared to ICNB. A higher VAS-score was recorded in c-ESPB compared to ICNB in the first 12 h after surgery. A significantly lower consumption of paracetamol in II postoperative day (p.o.d.) and tramadol in I and II p.o.d. was recorded in the c-ESPB group compared to the ICNB group. A higher dynamic VAS score was recorded at 24 h and 48 h in the ICNB group compared to the c-SAPB. No difference was found in safety, VAS-score and drug consumption between c-ESPB and c-SAPB at any given time, except for a higher tramadol request in c-SAPB in II p.o.d. CONCLUSIONS: C-ESPB and c-SAPB appear to have the same safety and analgesic efficacy when compared between them and to ICNB in Uniportal-VATS approach. C-ESPB showed a delayed onset of analgesic effect and a lower postoperative drug consumption compared to ICNB.
RESUMEN
Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related mortality worldwide. Notably, the incidence of lung cancer among never-smokers, predominantly women, has been rising in recent years. Among the various implicated risk factors, human papilloma virus (HPV) may play a role in the development of NSCLC in a certain subset of patients. The prevalence of high-risk HPV-DNA within human neoplastic lung cells varies across the world; however, the carcinogenetic role of HPV in NSCLC has not been completely understood. Bloodstream could be one of the routes of transmission from infected sites to the lungs, along with oral (through unprotected oral sex) and airborne transmission. Previous studies reported an elevated risk of NSCLC in patients with prior HPV-related tumors, such as cervical, laryngeal, or oropharyngeal cancer, with better prognosis for HPV-positive lung cancers compared to negative forms. On the other hand, 16% of NSCLC patients present circulating HPV-DNA in peripheral blood along with miRNAs expression. Typically, these patients have a poorly differentiated NSCLC, often diagnosed at an advanced stage. However, HPV-positive lung cancers seem to have a better response to target therapies (EGFR) and immune checkpoint inhibitors and show an increased sensitivity to platinum-based treatments. This review summarizes the current evidence regarding the role of HPV in NSCLC development, especially among patients with a history of HPV-related cancers. It also examines the diagnostic and prognostic significance of HPV, investigating new future perspectives to enhance cancer screening, diagnostic protocols, and the development of more targeted therapies tailored to specific cohorts of NSCLC patients with confirmed HPV infection.
