Prevalence and Impact of COVID-19 among Severe COPD Patients post Bronchoscopic Lung Volume Reduction Treatment with Endobronchial Valves.

BACKGROUND: The COVID-19 pandemic has a great impact on numberless aspects of our society. In our bronchoscopic lung volume reduction interventional program, we work with severe COPD patients on a daily basis. OBJECTIVES: We were interested in the prevalence and outcome of COVID-19, impact of the pandemic on daily life, and the vaccination coverage in our severe COPD patients who have been treated with one-way endobronchial valves. METHOD: A questionnaire, which consisted of questions related to the infection rate, treatment, and outcome of COVID-19 infections; feelings of anxiety related to the pandemic; adherence to preventive measures; and willingness to be vaccinated; was sent to our patients in June 2021. RESULTS: The questionnaire was sent to 215 patients, and the response rate was 100%. The vaccination rate was 97% in our surveyed population. The majority of patients (63%) indicated that they were quite or very anxious to get infected with COVID-19. Twenty-five (11.5%) patients were diagnosed with COVID-19, with none of these patients having been vaccinated at the time of infection. The infection rate reported in this study is comparable to that of the general Dutch population. However, the hospital admission rate and mortality rates are higher. CONCLUSIONS: Our results show that the SARS-CoV-2 infection rate in severe COPD patients treated with endobronchial valves was comparable with the general population; however, the hospital admission and mortality rates were worse.

Pre-COVID-19 National Mortality Trends in Open and Video-Assisted Lobectomy for Non-Small Cell Lung Cancer.

INTRODUCTION: In the current era of episode-based hospital reimbursements, it is important to determine the impact of hospital size on contemporary national trends in surgical technique and outcomes of lobectomy. METHODS: Patients aged >18 y undergoing open and video-assisted thoracoscopic surgery (VATS) lobectomy from 2008 to 2014 were identified using insurance claims data from the National Inpatient Sample. The impact of hospital size on surgical approach and outcomes for both open and VATS lobectomy were analyzed. RESULTS: Over the 7-y period, 202,668 lobectomies were performed nationally, including 71,638 VATS and 131,030 open. Although the overall number of lobectomies decreased (30,058 in 2008 versus 27,340 in 2014, P < 0.01), the proportion of VATS lobectomies increased (24.0% versus 46.9%), and open lobectomies decreased (76.0% versus 53.0%, all P < 0.01). When stratified by hospital size, small hospitals had a significant increase in the proportion of open lobectomies (6.4%-12.2%; P = 0.01) and trend toward increased number of VATS lobectomies (2.7%-12.2%). Annual mortality rates for VATS (range: 1.0%-1.9%) and open (range: 1.9%-2.4%) lobectomy did not significantly differ over time (all P > 0.05) but did decrease among small hospitals (4.1%-1.3% and 5.1%-1.1% for VATS and open, respectively; both P < 0.05). After adjusting for confounders, hospital bed size was not a predictor of in-hospital mortality. CONCLUSIONS: Utilization of VATS lobectomies has increased over time, more so among small hospitals. Mortality rates for open lobectomy remain consistently higher than VATS lobectomy (range 0.4%-1.4%) but did not significantly differ over time. This data can help benchmark hospital performance in the future.

Comparative early results of a robotics-assisted endoscope holder in single port thoracoscopic surgery in the era of COVID-19.

BACKGROUND: Innovations in surgical instruments have made single-port surgery more widely accepted and lead to a reduced demand for surgical assistants. As COVID-19 has ravaged the world, maintaining minimum medical staffing requirements and proper social distancing have become major topics of interest. We sought to evaluate the feasibility of applying the unisurgeon approach in single-port video-assisted thoracoscopic surgery aided by a robotic camera holder. METHODS: Operative time, blood loss, setup time, postoperative hospital stays, and the number of participating surgeons in single-port video-assisted thoracoscopic lung resections were gathered for investigation after the introduction of the ENDOFIXexo robotic endoscope holder system. In this cohort, we collected 213 patients who underwent single port video thoracoscope surgery, including 57 patients underwent robotic endoscope arm assisted surgery and case-matched 52 patients in the robotic arm-assisted group with patients in the human-assisted group through propensity score-matched analysis. RESULTS: In wedge resection, a single surgeon was able to completely operate on all lobes of target lesions. However, for anatomical resections, namely segmentectomy, the success rate was 95%, and for lobectomy, the success rate was only 64%. No significant differences between setup times, blood loss, or operative times between the two groups were observed. CONCLUSIONS: When an experienced uniport surgeon is assisted by a robotic endoscope holder, wedge resection is the most suitable procedure to be performed through unisurgeon single-port video-assisted thoracoscopic surgery without increasing setup time, operative time, or short-term complications. Verification of the technique's applicability for use in anatomic resections requires further investigation.

Powered articulation by the SigniaTM stapling system for stapling position adjustments: optimizing safe surgical margins in thoracoscopic sublobar resection.

Accumulation of experience and advances in techniques and instruments have enabled surgeons to perform video-assisted thoracic surgery (VATS) safely for sublobar resection, including segmentectomy and wedge resection. A key to successful VATS sublobar resection is to have adequate resection margins and the appropriate use of articulated surgical staplers is essential for this purpose. The SigniaTM stapling system (Covidien Japan, Tokyo) has been used extensively in the fields of thoracic surgery. Its features include high maneuverability with fully powered articulation, rotation, clamping, and firing, which the surgeon can control with one hand. We introduce the "sliding technique" using the SigniaTM system, which allows for adjustment of the resection lines of the pulmonary parenchyma to optimize safe surgical margins with minimal stapler movement, and without repetitively moving the stapler in and out of the pleural cavity, during VATS sublobar resection.

Lung Cancer Surgery in the Early Phase After Acute COVID-19 Pneumonitis.

A 65-year-old woman was diagnosed with early-stage lung cancer in 2020 and scheduled for robotic assisted-left upper lobectomy. Unfortunately, the patient contracted symptomatic COVID-19, resulting in postponement of lung resection. She was admitted for surgery 6 weeks after the acute infection. A preoperative computed tomographic scan showed widespread interstitial pneumonitis. However, the operation went ahead given concerns over tumor progression, albeit with a lesser resection to preserve lung tissue because the patient was slightly hypoxic. Her postoperative recovery was uneventful, and she was discharged 5 days later. Final histology confirmed a fully resected stage T1c N0 M0 adenocarcinoma of the lung.

Simultaneous versus staged resections for bilateral pulmonary metastases.

BACKGROUND: For patients with bilateral pulmonary metastases, staged resections have historically been the preferred surgical intervention. During the spring of 2020, the COVID-19 pandemic made patient travel to the hospital challenging and necessitated reduction in operative volume so that resources could be conserved. We report our experience with synchronous bilateral metastasectomies for the treatment of disease in both lungs. METHODS: Patients with bilateral pulmonary metastases who underwent simultaneous bilateral resections were compared with a cohort of patients who underwent staged resections. We used nearest-neighbor propensity score (1:1) matching to adjust for confounders. Perioperative outcomes were compared between groups using paired statistical analysis techniques. RESULTS: Between 1998 and 2020, 36 patients underwent bilateral simultaneous metastasectomies. We matched 31 pairs of patients. The length of stay was significantly shorter in patients undergoing simultaneous resection (median 3 vs. 8 days, p < .001) and operative time was shorter (156 vs. 235.5 min, p < .001) when compared to the sum of both procedures in the staged group. The groups did not significantly differ with regard to postoperative complications. CONCLUSION: In a carefully selected patient population, simultaneous bilateral metastasectomy is a safe option. A single procedure confers benefits for both the patient as well as the hospital resource system.

Salvage Lobectomy to Treat Necrotizing SARS-CoV-2 Pneumonia Complicated by a Bronchopleural Fistula.

We report a case of necrotizing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pneumonia complicated by a bronchopleural fistula and treated by decortication and salvage lobectomy. Owing to the unknown characteristics of the underlying SARS-CoV-2 infection, treatment of the abscess and bronchopleural fistula was delayed. This may have resulted in further deterioration of the patient, with ensuing multiple organ dysfunction. Complications of SARS-CoV-2 pneumonia, such as a bacterial abscess and a bronchopleural fistula, should be treated as if the patient were not infected with SARS-CoV-2.

Lobectomy for Hemorrhagic Lobar Infarction in a Patient With COVID-19.

Patients with severe coronavirus disease 2019 from infection with severe acute respiratory syndrome coronavirus 2 mount a profound inflammatory response and are predisposed to thrombotic complications. Pulmonary vein thrombosis is a rare disease process resulting in pulmonary congestion, infarction, and potential mortality. This report describes a patient with coronavirus disease 2019 requiring venovenous extracorporeal membrane oxygenation for hypoxic respiratory failure who developed hemorrhagic infarction of the right lower lobe. During emergency exploration the patient was found to have a right inferior vein thrombosis and marked lobar hemorrhage mandating lobectomy.

Pulmonary Lobectomy After COVID-19.

Concomitant coronavirus disease 19 (COVID-19) is a major risk factor for complications in any type of surgical procedure, especially in thoracic surgery, were the primary organ involved, the lung, is manipulated to perform parenchymal resection. However, it is not clear whether previous infection from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may lead to increased morbidity and mortality for subsequent procedures once radiologic resolution is achieved. We report a young patient with lung cancer who successfully underwent a right upper lobectomy for primary adenocarcinoma by video-assisted thoracoscopic surgery with no complication in the early postoperative phase.

Clinical courses and outcomes of five patients with primary lung cancer surgically treated while affected by Severe acute respiratory syndrome coronavirus 2.

OBJECTIVES: There is currently a lack of clinical data on the novel beta-coronavirus infection [caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)] and concomitant primary lung cancer. Our goal was to report our experiences with 5 patients treated for lung cancer while infected with SARS-CoV-2. METHODS: We retrospectively evaluated 5 adult patients infected with SARS-CoV-2 who were admitted to our thoracic surgery unit between 29 January 2020 and 4 March 2020 for surgical treatment of a primary lung cancer. Clinical data and outcomes are reported. RESULTS: All patients were men with a mean age of 74.0 years (range 67-80). Four of the 5 patients (80%) reported chronic comorbidities. Surgery comprised minimally invasive lobectomy (2 patients) and segmentectomy (1 patient), lobectomy with en bloc chest wall resection (1 patient) and pneumonectomy (1 patient). Mean chest drain duration was 12.4 days (range 8-22); mean hospital stay was 33.8 days (range 21-60). SARS-CoV-2-related symptoms were fever (3 patients), persistent cough (3 patients), diarrhoea (2 patients) and syncope (2 patients); 1 patient reported no symptoms. Morbidity related to surgery was 60%; 30-day mortality was 40%. Two patients (1 with a right pneumonectomy, 74 years old; 1 with a lobectomy with chest wall resection and reconstruction, 70 years old), developed SARS-CoV-2-related lung failure leading to death 60 and 32 days after surgery, respectively. CONCLUSIONS: Lung cancer surgery may represent a high-risk factor for developing a severe case of coronavirus disease 2019, particularly in patients with advanced stages of lung cancer. Additional strategies are needed to reduce the risk of morbidity and mortality from SARS-CoV-2 infection during treatment for lung cancer.

Perspectives in surgical and anaesthetic management of lung cancer in the era of coronavirus disease 2019 (COVID-19).

Early in 2020, coronavirus disease 2019 (COVID-19) quickly spread globally, giving rise to a pandemic. In this critical scenario, patients with lung cancer need to continue to receive optimal care and at the same be shielded from infection with the potentially severe acute respiratory syndrome coronavirus 2. Upgrades to the prevention and control of infection have become paramount in order to lower the risk of hospital contagion. Aerosol-generating procedures such as endotracheal intubation or endoscopic procedures may expose health care workers to a high risk of infection. Moreover, thoracic anaesthesia usually requires highly complex airway management procedures because of the need for one-lung isolation and one-lung ventilation. Therefore, in the current pandemic, providing a fast-track algorithm for scientifically standardized diagnostic criteria and treatment recommendations for patients with lung cancer is urgent. Suggestions for improving existing contagion control guidelines are needed, even in the case of non-symptomatic patients who possibly are responsible for virus spread. A COVID-19-specific intraoperative management strategy designed to reduce risk of infection in both health care workers and patients is also required.
