Review
BACKGROUND
An ever-increasing number of studies have reported an increased incidence of spontaneous pulmonary barotrauma such as pneumothorax, pneumomediastinum, and subcutaneous emphysema in patients with COVID-19. We conducted this systematic review and meta-analysis to assess the value and significance of the available data.
METHODS
A thorough systematic search was conducted to identify studies of barotrauma in hospitalized patients with COVID-19. Data analysis of case reports was done using a statistical package for the social sciences (SPSS) version 22, and meta-analysis was performed using CMA-3.
RESULTS
We identified a total of 4488 studies after thorough database searching.118 case reports and series, and 15 observational studies were included in the qualitative analysis. Fifteen studies were included in the quantitative analysis. The observational studies reported barotrauma in 4.2% (2.4-7.3%) among hospitalized patients; 15.6% (11-21.8%) among critically ill patients; and 18.4% (13-25.3%) in patients receiving invasive mechanical ventilation, showing a linear relationship of barotrauma with the severity of the disease. In addition, barotrauma was associated with a longer length of hospital stay, more extended ICU stay, and higher in-hospital mortality. Also, a slightly higher odds of barotrauma was seen in COVID-19 ARDS compared with non-COVID-19 ARDS.
CONCLUSION
COVID-19 pneumonia is associated with a higher incidence of barotrauma. It presents unique challenges for invasive and non-invasive ventilation management. Further studies are required to unravel the underlying pathophysiology and develop safer management strategies.

Meta-Analysis
BACKGROUND
Vascular punctures are widely used in clinical applications; however, clinical trials have identified complications and poor prognosis for patients undergoing common peripheral vein puncture as compared to ultrasound-guided peripheral venipuncture and catheterization. Ultrasound-guided peripheral venipuncture and catheterization is accurate, simple, has fewer associated complications, and will gradually take the place of common peripheral vein puncture.
METHODS
To study the safety of ultrasound-guided peripheral venous catheterization, a meta-analysis was conducted of relevant articles dating from establishment date of the database (such as PubMed, MEDLINE and EMBASE) to March 2021, with the search keywords being peripheral venipuncture, ultrasound guidance, vascular injury rate, and hematoma formation rate. A total of 8 trials were used to determine accuracy indicators, which included puncture failure rate, arterial injury rate, hematoma formation rate, pneumothorax incidence rate, and hemothorax incidence rate.
RESULTS
There were statistically significant differences between the two methods for peripheral venipuncture and catheterization in terms of puncture failure rate [odds ratio (OR) =0.08; 95% CI: 0.04-0.16; P<0.00001], incidence of vascular injury (OR =0.15; 95% CI: 0.07-0.32; P<0.00001), probability of hematoma formation during the puncture process (OR =0.24; 95% CI: 0.08-0.69; P=0.008), and probability of pneumothorax during puncture (OR =0.10; 95% CI: 0.02-0.55; P=0.008).
DISCUSSION
Eight articles were included for meta-analysis. Ultrasound-guided peripheral venipuncture and catheterization is a commonly used puncture method for patients needing rapid fluid infusion with pressure or a pressure pump, repeated transfusion of blood product, or multiple daily venous blood drawing test. The results were very clear, and the puncture failure rate and other complications of ultrasound-guided peripheral venipuncture catheterization were low.

Meta-Analysis
Evaluation and Management of Primary Spontaneous Pneumothorax in Adolescents and Young Adults: A Systematic Review From the APSA Outcomes & Evidence-Based Practice Committee.
INTRODUCTION
Controversy exists in the optimal management of adolescent and young adult primary spontaneous pneumothorax. The American Pediatric Surgical Association (APSA) Outcomes and Evidence-Based Practice Committee performed a systematic review of the literature to develop evidence-based recommendations.
METHODS
Ovid MEDLINE, Elsevier Embase, EBSCOhost CINAHL, Elsevier Scopus, and Wiley Cochrane Central Register of Controlled Trials databases were queried for literature related to spontaneous pneumothorax between January 1, 1990, and December 31, 2020, addressing (1) initial management, (2) advanced imaging, (3) timing of surgery, (4) operative technique, (5) management of contralateral side, and (6) management of recurrence. The Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines were followed.
RESULTS
Seventy-nine manuscripts were included. Initial management of adolescent and young adult primary spontaneous pneumothorax should be guided by symptoms and can include observation, aspiration, or tube thoracostomy. There is no evidence of benefit for cross-sectional imaging. Patients with ongoing air leak may benefit from early operative intervention within 24-48 h. A video-assisted thoracoscopic surgery (VATS) approach with stapled blebectomy and pleural procedure should be considered. There is no evidence to support prophylactic management of the contralateral side. Recurrence after VATS can be treated with repeat VATS with intensification of pleural treatment.
CONCLUSIONS
The management of adolescent and young adult primary spontaneous pneumothorax is varied. Best practices exist to optimize some aspects of care. Further prospective studies are needed to better determine optimal timing of operative intervention, the most effective operation, and management of recurrence after observation, tube thoracostomy, or operative intervention.

Review
BACKGROUND/AIM
Pulmonary metastases are the second most common site of metastasis in colorectal cancer after the liver, and microwave ablation (MWA) for its treatment has grown in popularity in patients who are not suitable for pulmonary metastatectomy. However, its long-term efficacy remains unknown.
MATERIALS AND METHODS
A systematic review was conducted in July 2022 in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement, using PubMed, EMBASE, Scopus, and Cochrane databases. Studies adopting MWA for colorectal cancer pulmonary metastases were included.
RESULTS
A total of 488 lesions were ablated in 230 patients across eight studies. The median duration of ablation was 10 minutes. The mean length of stay in hospital was 2.3 days. Complications included pneumothorax in 128 (52%) patients; pneumonia, which occurred in 4 (1.7%) patients, and pulmonary haemorrhage in 23 (10.0%) patients. Complete remission was achieved in 85 (37.0%) patients, local control was achieved in 103 (44.8%) patients, and residual or progressive disease remained in 85 (37.0%). Survival post ablation at 1 year was 89.2% and at 3 years was 40.3%. Post-ablation disease-free survival was 43.2% at 3 years.
CONCLUSION
MWA is an alternative treatment for pulmonary metastases of colorectal cancer. It has competitive theoretical properties and local recurrence rate compared to radiofrequency ablation.

Comparative Study Meta-Analysis
BACKGROUND
Primary spontaneous pneumothorax (PSP) prevalence is typically higher in juvenile patients than in adults. We aimed to evaluate the optimal treatment for primary spontaneous pneumothorax and its efficacy and safety in juveniles.
MATERIALS AND METHODS
We searched PubMed, Embase, and Cochrane databases for eligible studies published from database inception to October 10, 2020, and conducted a systematic review and meta-analysis according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The primary and secondary outcomes were recurrence rate and hospital stay length, respectively. Odds ratios (OR) and mean differences were used for quantitatively analyzing binary and continuous outcomes, respectively. In total, nine retrospective studies with 1,452 juvenile patients (aged <21) were included for the quantitative analysis. The surgical approach led to a lower recurrence rate than did conservative approaches (OR: 1.95, 95% confidence interval: 1.15-3.32). Moreover, the recurrence rate was low in patients who underwent conservative treatment first and received surgery later.
CONCLUSIONS
Surgical approach for first-line management might have a greater effect on recurrence prevention than do conservative approaches. An upfront surgery might be an optimal choice for juvenile primary spontaneous pneumothorax.

Review
Bevacizumab is a monoclonal anti-vascular endothelial growth factor (VEGF) antibody that binds to and makes all of the VEGF isoforms inactive, and thus prevents angiogenesis, development, and the spread of the tumor. The most reported side effects after administering bevacizumab include bleeding, high blood pressure, heart failure, proteinuria, thrombosis, and gastrointestinal perforation. Pneumothorax has rarely been reported as a complication of bevacizumab, but with an unclear mechanism. This article aims to explore the occurrence of pneumothorax as a side effect after using bevacizumab through a systematic review of current case reports published on the topic. A literature search was conducted using PubMed, Google Scholar, ScienceDirect, and Directory of Open Access through the utilization of appropriate keywords, and case reports were selected based on predefined inclusion and exclusion criteria. Our results encompass five case reports that were further evaluated for demographic, clinical, and treatment parameters. This systematic review concludes that pneumothorax can occur after bevacizumab-containing chemotherapy although this side effect is relatively rare. Awareness regarding this possible side effect can assist clinicians during their practice in considering pneumothorax as a possible differential diagnosis when encountering patients presenting with pulmonary symptoms after starting bevacizumab-containing chemotherapy; hence, timely diagnosis and treatment can save a life.

Review
BACKGROUND
Tension pneumothorax (TPT) is a frequent life-threat following thoracic injury. Time-critical decompression of the pleural cavity improves survival. However, whilst paramedics utilise needle thoracostomy (NT) and/or finger thoracostomy (FT) in the prehospital setting, the superiority of one technique over the other remains unknown.
AIM
To determine and compare procedural success, complications and mortality between NT and FT for treatment of a suspected TPT when performed by paramedics.
METHODS
We searched four databases (Ovid Medline, PubMed, CINAHL and Embase) from their commencement until 25 August 2020. Studies were included if they analysed patients suffering from a suspected TPT who were treated in the prehospital setting with a NT or FT by paramedics (or local equivalent nonphysicians).
RESULTS
The search yielded 293 articles after duplicates were removed of which 19 were included for final analysis. Seventeen studies were retrospective (8 cohort; 7 case series; 2 case control) and two were prospective cohort studies. Only one study was comparative, and none were randomised controlled trials. Most studies were conducted in the USA (n=13) and the remaining in Australia (n=4), Switzerland (n=1) and Canada (n=1). Mortality ranged from 12.5% to 79% for NT and 64.7% to 92.9% for FT patients. A higher proportion of complications were reported among patients managed with NT (13.7%) compared to FT (4.8%). We extracted three common themes from the papers of what constituted as a successful pleural decompression; vital signs improvement, successful pleural cavity access and absence of TPT at hospital arrival.
CONCLUSION
Evidence surrounding prehospital pleural decompression of a TPT by paramedics is limited. Available literature suggests that both FT and NT are safe for pleural decompression, however both procedures have associated complications. Additional high-quality evidence and comparative studies investigating the outcomes of interest is necessary to determine if and which procedure is superior in the prehospital setting.

BACKGROUND
Primary spontaneous pneumothorax (PSP) has several commonly used management strategies: observation, aspiration, and chest tube placement. Economic modelling of pooled data comparing techniques has not been performed.
RESEARCH QUESTION
Based on studies from the past 20 years, which approach to management of PSP delivers the highest utility?
STUDY DESIGN AND METHODS
A systematic review of PSP management strategies (observation, aspiration, or chest tube placement) included in the Medline and EMBASE databases from January 1, 2000, through April 10, 2020, was conducted. Text screening, bias assessment, and data extraction were performed by two authors (G. E. and C. A. P.). Inclusion and exclusion criteria were defined a priori. The primary outcome was PSP resolution after the initial intervention. Secondary outcomes were PSP recurrence, length of stay, rate of surgical management, and complications. The meta-analysis compared treatment arms; dichotomous outcomes were reported as relative risk (RRs) and continuous outcomes were reported as mean differences. A cost-utility analysis within the Canadian health care system context with deterministic and probabilistic sensitivity analyses was performed.
RESULTS
Five thousand one hundred seventy-nine articles were identified; after screening, 22 articles were included. Most trials showed a high risk of bias, but randomized trials showed a lower risk. Compared with chest tube placement, observation (mean difference, 5.17; 95% CI, 3.75-6.59; P < .01; I = 62%) and aspiration (mean difference, 2.72; 95% CI, 2.39-3.04; P < .01; I = 0%) showed a shorter length of stay. Compared with observation, chest tube placement (RR, 0.81; 95% CI, 0.71-0.91; P < .01; I = 62%) and aspiration (RR, 0.73; 95% CI, 0.61-0.88; P < .01; I = 67%) showed higher resolution without additional intervention. Two-year recurrence rates did not differ between management strategies. Observation showed the best utility (0.82) and lowest cost; observation was the optimal strategy in 98.2% of Monte Carlo simulations.
INTERPRETATION
Observation is the dominant choice compared with aspiration and chest tube placement for PSP. It should be considered as the first-line therapy in appropriately selected patients.

Meta-Analysis Review
BACKGROUND
Surgical approach is the most effective treatment for primary spontaneous pneumothorax. The two most widely adopted surgical methods are mechanical abrasion and apical pleurectomy, in addition to bullectomy. We performed a systematic review and meta-analysis to examine which technique is superior in treating primary spontaneous pneumothorax.
METHODS
PubMed, MEDLINE and EMBASE databases were searched for studies published between January 2000 to September 2022 comparing mechanical abrasion and apical pleurectomy for treatment of primary spontaneous pneumothorax. The primary outcome was pneumothorax recurrence. Secondary outcomes included post-operative chest tube duration, hospital length of stay, operative time and intra-operative of blood loss.
RESULTS
Eight studies were eligible for inclusion involving 1,613 patients. There was no difference in the rate of pneumothorax recurrence between pleural abrasion and pleurectomy (RR: 1.34; 95% CI: 0.94 to 1.92). However, pleural abrasion led to shorter hospital length of stay (MD: -0.25; 95% CI: -0.51 to 0.00), post-operative chest tube duration (MD: -0.30; 95% CI: -0.56 to -0.03), operative time (MD: -13.00; 95% CI -15.07 to 10.92) and less surgical blood loss (MD: -17.77; 95% CI: -24.36 to -11.18).
CONCLUSION
Pleural abrasion leads to less perioperative patient burden and shorter hospital length of stay without compromising the rate of pneumothorax recurrence when compared to pleurectomy. Thus, pleural abrasion is a reasonable first choice surgical procedure for management of primary spontaneous pneumothorax.

INTRODUCTION
There are various reports of air leaks with coronavirus disease 2019 (COVID-19). We undertook a systematic review of all published case reports and series to analyse the types of air leaks in COVID-19 and their outcomes.
METHODS
The literature search from PubMed, Science Direct, and Google Scholar databases was performed from the start of the pandemic till 31 March 2021. The inclusion criteria were case reports or series on (1) laboratory-confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, (2) with the individual patient details, and (3) reported diagnosis of one or more air leak syndrome (pneumothorax, subcutaneous emphysema, pneumomediastinum, pneumoperitoneum, pneumopericardium).
RESULTS
A total of 105 studies with 188 patients were included in the final analysis. The median age was 56.02 (SD 15.53) years, 80% males, 11% had previous respiratory disease, and 8% were smokers. Severe or critical COVID-19 was present in 50.6% of the patients. Pneumothorax (68%) was the most common type of air leak. Most patients (56.7%) required intervention with lower mortality (29.1% vs. 44.1%, p = 0.07) and intercostal drain (95.9%) was the preferred interventional management. More than half of the patients developed air leak on spontaneous breathing. The mortality was significantly higher in patients who developed air leak with positive pressure ventilation (49%, p < 0.001) and required escalation of respiratory support (39%, p = 0.006).
CONCLUSION
Air leak in COVID-19 can occur spontaneously without positive pressure ventilation, higher transpulmonary pressures, and other risk factors like previous respiratory disease or smoking. The mortality is significantly higher if associated with positive pressure ventilation and escalation of respiratory support.
