Project description:Background and objectiveProlonged air leak (PAL) following lung resection is related to an increase in morbidity and both direct and indirect costs. In recent years, robotic-assisted thoracic surgery (RATS) has proved to be a safe technique with comparable perioperative outcomes of video-assisted thoracic surgery (VATS), optimal oncological results, and potential advantages in case of sublobar resection. We here focus on the incidence and clinical impact of PAL in the field of robotic surgery and discuss the therapeutic strategies currently available.MethodsWe conducted a search on PubMed/MEDLINE and Scopus database from inception until May 27th 2022 to select the relevant literature published in English exploring the occurrence of PAL following RATS.Key content and findingsThe implementation of robotic surgery led to a significant reduction in PAL occurrence after pulmonary resection compared to open thoracotomy, while there is still no clear advantage with respect to VATS. However, the enhanced dexterity and improved visualization of the robot seem to particularly valuable in case of sublobar lung resection, especially complex ones. Accurate selection of patients based on the presence of risk factors allows the implementation of intraoperative measures in order to reduce the occurrence of PAL.ConclusionsRobotic lung resection is a safe technique, advantageous compared to traditional open thoracotomy in terms of PAL occurrence reduction and it is a valid alternative to manual VATS. Moreover, with the extension of indications for sublobar resection in the treatment of early stage lung cancer, RATS may prove to be the technique of choice thanks to its intrinsic advantages.

Project description:Prolonged air leak (PAL), defined as air leak more than 5 days after lung resection, has been associated with various adverse outcomes. However, studies on intraoperative risk factors for PAL are not sufficient. We investigated whether the intraoperative ventilatory leak (VL) can predict PAL. A retrospective study of 1060 patients with chest tubes after lung resection was conducted. Tidal volume data were retrieved from the electronic anesthesia records. Ventilatory leak (%) was calculated as [(inspiratory tidal volume-expiratory tidal volume)/ inspiratory tidal volume × 100] and was measured after restart of two-lung ventilation. Cox proportional hazards regression analysis was performed using VL as a predictor, and PAL as the dependent outcome. The odds ratio of the VL was then adjusted by adding possible risk factors including patient characteristics, pulmonary function and surgical factors. The incidence of PAL was 18.7%. VL >9.5% was a significant predictor of PAL in univariable analysis. VL remained significant as a predictor of PAL (1.59, 95% CI, 1.37-1.85, P <0.001) after adjusting for 7 additional risk factors including male gender, age >60 years, body mass index <21.5 kg/m2, forced expiratory volume in 1 sec <80%, thoracotomy, major lung resection, and one-lung ventilation time >2.1 hours. C-statistic of the prediction model was 0.80 (95% CI, 0.77-0.82). In conclusion, VL was a quantitative measure of intraoperative air leakage and an independent predictor of postoperative PAL. Monitoring VL during lung resection may be uselful in recommending additional surgical repair or use of adjuncts and thus, help reduce postoperative PAL.

Project description:BackgroundProlonged air leak (PAL) represents a common complication after lung resection. This study aims to analyze the risk factors for the development of a PAL, its impact on the postoperative outcome and to estimate additional treatment costs.MethodsA single center database was queried for all patients scheduled for video-assisted thoracoscopic surgery for primary lung cancer. In total, 957 patients between 2009 and 2021 were analyzed. Exclusion criteria was pneumonectomy. Collected data included demographics and perioperative data (e.g., duration of surgery, postoperative infections, air leak duration etc.). PAL was defined as an air leak lasting for 5 days or longer. The PAL cohort included 103 patients, the non-PAL included 854 patients. Univariate analysis and binomial logistic regression were performed. Cost calculation was performed using available data from prior publications to estimate treatment costs.ResultsMale sex, chronic obstructive pulmonary disease (COPD) and low body mass index (BMI) showed to be risk factors for the development of postoperative PAL (P<0.001). Using these risk factors, a risk prediction score for PAL has been established. A subgroup analysis showed a significantly higher rate of sarcopenia in patients with PAL (P<0.001). The mean duration until removal of chest drains and length of stay (LOS) was significantly longer in the PAL cohort (14.2 vs. 4.4 days, P<0.001; 19.8 vs. 9.3 days, P<0.001). Also, the duration of the operation was longer in PAL patients (179.1 vs. 161.2 minutes, P=0.001). Patients with PAL had an elevated risk for postoperative infections [odds ratio (OR) 3.211, 31.1% vs. 12.3%, P<0.001]. As a result of a prolonged LOS, estimated treatment costs were significantly higher for PAL, ranging from 2,888.2 to 12,342.8 € depending on available cost bases compared to the non-PAL cohort, which ranged from 1,370.5 to 5,856.8 € (P<0.001).ConclusionsPAL is a frequent complication that prolongs the LOS after thoracic surgery and, according to the literature, results in elevated readmission rates, leading to excess health care costs. Risk factors for PAL are well established. Preoperative treatment of sarcopenia and dismal nutritional status might alter the risk. As measures to prevent PAL are otherwise limited, guidelines for effective management of PAL need to be established.

Project description:ObjectivesProlonged air leak (PAL; >5 days) following lung resection is associated with postoperative morbidity. We investigated factors associated with PAL and PAL requiring intervention.MethodsRetrospective review of all patients undergoing lobectomy, segmentectomy or wedge resection from 2016 to 2019 at our institution. Bronchoplastic reconstructions and lung-volume reduction surgeries were excluded. Incidence and risk factors for PAL and PAL requiring intervention were evaluated.ResultsIn total, 2384 patients were included. PAL incidence was 5.4% (129/2384); 22.5% (29/129) required intervention. PAL patients were more commonly male (56.6% vs 39.7%), older (mean age 69 vs 65 years) and underwent lobectomy or thoracotomy (all P < 0.001). Patients with PAL had longer length of stay (9 vs 3 days), more discharge needs and increased odds of complication (all P < 0.050).Twenty-nine patients required intervention (9 chest tubes; 4 percutaneous drains; 16 operations). In 50% of operative interventions, an air leak source was identified; however, the median time from intervention to resolution was 13 days. Patients requiring intervention had increased steroid use, lower diffusion capacity for carbon monoxide and twice the length of stay versus PAL patients (all P < 0.050).On univariable analysis, forced expiratory volume in 1 s (FEV1) <40%, diffusion capacity for carbon monoxide <50%, steroid use and albumin <3 had increased odds of intervention (P < 0.050).ConclusionsAge, gender and operative technique were related to PAL development. Patients with worse forced expiratory volume in 1 s or diffusion capacity for carbon monoxide, steroid use or poor nutrition were less likely to heal on their own, indicating a population that could benefit from earlier intervention.

Project description:BackgroundThe objective of this study was to create a simple preoperative tool to assess the risk of prolonged air leak (PAL) using The Society of Thoracic Surgeons General Thoracic Surgery Database (STS GTSD).MethodsThe STS GTSD was queried for patients who underwent elective lung cancer resection between 2009 and 2016. Exclusion criteria included pneumonectomy, sleeve lobectomy, chest wall resection, bilateral procedures, and patients with incomplete data sets. The primary outcome was PAL exceeding 5 days. Multivariable logistic regression was used to identify risk factors for a PAL. Model coefficients were used to generate a PAL score (PALS). The approach was cross-validated in 100 replications of a training set consisting of two-thirds of the cohort that was randomly selected and a validation set of remaining patients.ResultsA total of 52,198 patients from the STS GTSD met inclusion criteria, with an overall rate of PAL of 10.4% (n = 5453). Final variables incorporated into the PALS included body mass index of 25 kg/m2 or less (7 points), lobectomy or bilobectomy (6 points), forced expiratory volume in 1 second of 70% predicted or less (5 points), male sex (4 points), and right upper lobe procedure (3 points). A cumulative PALS exceeding 17 points stratified patients as high-risk or low-risk for PAL (19.6% vs 9% rate of PAL) with a cross-validated mean negative predictive value of 91%, positive predictive value of 19%, sensitivity of 30%, specificity of 85%, and correctly classifies 79% of patients.ConclusionsThe PALS is a simple preoperative clinical tool that can reliably risk-stratify patients for PAL who are undergoing lung cancer resection.

Project description:BackgroundWe designed this study to investigate the rate and risk factors of prolonged air leak (PAL) in patients undergoing pulmonary segmentectomy in our unit.MethodsWe performed a retrospective cohort study on 191 patients undergoing pulmonary segmentectomy (January 2017-August 2021). A PAL was defined as an air leak >5 days.ResultsOne hundred and sixty-eight segmentectomies were performed using video-assisted thoracoscopic surgery (VATS), 13 were open operations and 10 were robotic. PAL occurred in 36 patients (19%). Their average post-operative stay was 2.4 days longer than those without PAL. Logistic regression analysis showed that a low preoperative carbon monoxide lung diffusion capacity (DLCO) (OR 0.98, P<0.001), low body mass index (BMI) (OR 0.95, P=0.002) and the performance of complex segmentectomies (OR 2.2, P<0.001). were significantly associated with PAL.ConclusionsPulmonary segmentectomies are associated with a not negligible risk of PAL when using real world data, especially in patients with compromised pulmonary function and after complex segmentectomies. This finding is useful to inform the decision-making process.

Project description:BackgroundProlonged air leak (PAL) due to an alveolar-pleural fistula (APF) is the most common complication after lung surgery. PAL is associated with an increased risk of morbidity and mortality, a longer chest tube duration, hence a prolonged hospitalization. Management of PAL may be challenging, and the thoracic surgeon should be aware of the possible therapeutic strategies.MethodsA systematic literature review was performed in PubMed, Cochrane Library, EMBASE, Ovid and Google Scholar. Title, abstract and full-text screening was performed, followed by structured data extraction, methodological quality assessment and Cochrane risk of bias assessment. Inclusion criteria were: case-control studies/randomized controlled trials (RCTs) comparing the new tested method with the standard of care to manage PAL after lung surgery; PAL due to APF; at least 10 patients; English-written papers.ResultsA total of 942 initial papers from literature search, resulted in 43 papers after the selection. This systematic review found that the use of intraoperative measures as surgical sealants or pleural tenting, as well as a proper management of the chest drain and the use of blood patch or sclerosant agents seem to reduce postoperative air leaks incidence and/or duration and length of chest drain stay and hospitalization.ConclusionsDifferent measures have been described in literature to manage or prevent postoperative PAL. Most of them seem to be safe and efficient if compared to the "wait and see" strategy, even if large comparative studies that standardize the intra- and post-operative management of APF after lung resection are lacking and, actually, hard to conceptualize. However, there is a large consensus on the value of a preoperative PAL-risk stratification and on the necessity of tailoring PAL management or prevention's strategy and its timing on each patient's features.

Project description:ObjectivesPersistent air leak (PAL; >5 days after surgery) is the most common complication after pulmonary resection and associated with prolonged hospital stay and increased morbidity. Literature is contradictory about the prevention and treatment of PAL. Variation is therefore hypothesized. The aim of this study is to understand the variation in the incidence, preventive management and treatment of PAL.MethodsData from the Dutch Lung Cancer Audit for Surgery were combined with results of an online survey among Dutch thoracic surgeons. The national incidence of PAL and case-mix corrected between-hospital variation were calculated in patients who underwent an oncological (bi)lobectomy or segmentectomy between January 2012 and December 2018. By multivariable logistic regression, factors associated with PAL were assessed. A survey was designed to assess variation in (preventive) management and analysed using descriptive statistics. Hospital-level associations between management strategies and PAL were assessed by univariable linear regression.ResultsOf 12 382 included patients, 9.0% had PAL, with a between-hospital range of 2.6-19.3%. Factors associated with PAL were male sex, poor lung function, low body mass index, high American Society of Anesthesiologists (ASA) score, pulmonary comorbidity, upper lobe resection, (bi)lobectomy (vs segmentectomy), right-sided tumour and robotic-assisted thoracic surgery. Perioperative (preventive) management of PAL differed widely between hospitals. When using water seal compared to suction drainage, the average incidence of PAL decreased 2.9%.ConclusionsIn the Netherlands, incidence and perioperative (preventive) management of PAL vary widely. Using water seal instead of suction drainage and increasing awareness are potential measures to reduce this variation.
