Diagnosis of hemidiaphragm paralysis: refine ultrasound criteria.

Background: Ultrasound has demonstrated its interest in the analysis of diaphragm function in patients with respiratory failure. The criteria used to diagnose hemidiaphragm paralysis are not well defined. Methods: The aim of this observational retrospective study was to describe the ultrasound findings in 103 patients with diaphragm paralysis, previously diagnosed by conventional methods after various circumstances such as trauma or surgery. The ultrasound study included the recording of excursions of both diaphragmatic domes and the measurement of inspiratory thickening. Results: On paralyzed hemidiaphragm, thickening was less than 20% in all patients during deep inspiration. Thinning was recorded in 53% of cases. In some cases, the recording of the thickening could be difficult. The study of motion during voluntary sniffing reported a paradoxical excursion in all but one patient. During quiet breathing, an absence of movement or a paradoxical displacement was observed. During deep inspiration, a paradoxical motion at the beginning of inspiration followed by a reestablishment of movement in the cranio-caudal direction was seen in 82% of cases. In some patients, there was a lack of movement followed, after an average delay of 0.4 s, by a cranio-caudal excursion. Finally, in 4 patients no displacement was recorded. Evidence of hyperactivity (increased inspiratory thickening and excursion) of contralateral non-paralyzed hemidiaphragm was observed. Conclusion: To accurately detect hemidiaphragm paralysis, it would be interesting to combine the ultrasound study of diaphragm excursion and thickening. The different profiles reported by our study must be known to avoid misinterpretation.

S erratus anterior plane block alone, paravertebral block alone and their combination in video-assisted thoracoscopic surgery: the THORACOSOPIC double-blind, randomized trial.

OBJECTIVES: Serratus anterior plane block (SAPB) and paravertebral block (PVB) are well known to reduce pain levels after video-assisted thoracoscopic surgery (VATS). However, the relative efficacies of each block and a combination of the 2 have not been fully characterized. The objective of the present study was to assess the efficacy of PVB alone, SAPB alone and the combination of PVB and SAPB with regard to the occurrence and intensity of pain after VATS. METHODS: We conducted the THORACOSOPIC single-centre, double-blind, randomized trial in adult patients due to undergo elective VATS lung resection. The participants were randomized to PVB only, SAPB only and PVB + SAPB groups. The primary end-point was pain on coughing on admission to the postanaesthesia care unit. The secondary end-points were postoperative pain at rest and on coughing at other time points and the cumulative opioid consumption. Pain was scored on a visual analogue scale. RESULTS: One-hundred and fifty-six patients (52 in each group) were included. On admission to the postanaesthesia care unit, the 3 groups did not differ significantly with regard to the pain on coughing: the visual analogue scale score was 3 (0-6), 4 (0-8) and 2 (0-6) in the PVB, SAPB and PVB + SAPB groups, respectively (P = 0.204). During postoperative care, the overall pain score was significantly lower in the SABP + PVP group at rest and on cough. CONCLUSIONS: The combination of SABP + PVB could be beneficial for pain management in VATS in comparison to SABP or PVB alone.

Effectiveness of Surgeon-Performed Paravertebral Block Analgesia for Minimally Invasive Thoracic Surgery: A Randomized Clinical Trial.

Importance: In minimally invasive thoracic surgery, paravertebral block (PVB) using ultrasound (US)-guided technique is an efficient postoperative analgesia. However, it is an operator-dependent process depending on experience and local resources. Because pain-control failure is highly detrimental, surgeons may consider other locoregional analgesic options. Objective: To demonstrate the noninferiority of PVB performed by surgeons under video-assisted thoracoscopic surgery (VATS), hereafter referred to as PVB-VATS, as the experimental group compared with PVB performed by anesthesiologists using US-guided technique (PVB-US) as the control group. Design, Setting, and Participants: In this single-center, noninferiority, patient-blinded, randomized clinical trial conducted from September 8, 2020, to December 8, 2021, patients older than 18 years who were undergoing a scheduled minimally invasive thoracic surgery with lung resection including video-assisted or robotic approaches were included. Exclusion criteria included scheduled open surgery, any antalgic World Health Organization level greater than 2 before surgery, or a medical history of homolateral thoracic surgery. Patients were randomly assigned (1:1) to an intervention group after general anesthesia. They received single-injection PVB before the first incision was made in the control group (PVB-US) or after 1 incision was made under thoracoscopic vision in the experimental group (PVB-VATS). Interventions: PVB-VATS or PVB-US. Main Outcomes and Measures: The primary end point was mean 48-hour post-PVB opioid consumption considering a noninferiority range of less than 7.5 mg of opioid consumption between groups. Secondary outcomes included time of anesthesia, surgery, and operating room occupancy; 48-hour pain visual analog scale score at rest and while coughing; and 30-day postoperative complications. Results: A total of 196 patients were randomly assigned to intervention groups: 98 in the PVB-VATS group (mean [SD] age, 64.6 [9.5] years; 53 female [54.1%]) and 98 in the PVB-US group (mean [SD] age, 65.8 [11.5] years; 62 male [63.3%]). The mean (SD) of 48-hour opioid consumption in the PVB-VATS group (33.9 [19.8] mg; 95% CI, 30.0-37.9 mg) was noninferior to that measured in the PVB-US group (28.5 [18.2] mg; 95% CI, 24.8-32.2 mg; difference: -5.4 mg; 95% CI, -∞ to -0.93; noninferiority Welsh test, P ≤ .001). Pain score at rest and while coughing after surgery, overall time, and postoperative complications did not differ between groups. Conclusions and Relevance: PVB placed by a surgeon during thoracoscopy was noninferior to PVB placed by an anesthesiologist using ultrasonography before incision in terms of opioid consumption during the first 48 hours.

Is the Epithor conversion score reliable in robotic-assisted surgery anatomical lung resection?

OBJECTIVES: Despite an improvement in surgical abilities, the need for an intraoperative switch from a minimally invasive procedure towards an open surgery (conversion) still remains. To anticipate this risk, the Epithor conversion score (ECS) has been described for video-assisted thoracoscopic surgery (VATS). Our objective was to determine if this score, developed for VATS, is applicable in robotic-assisted thoracoscopic surgery (RATS). METHODS: This was a retrospective monocentric study from January 2006 to June 2022, and data were obtained from the EPITHOR database. Patients included were those who underwent anatomic lung resection either by VATS or RATS. The ECS was calculated for all patients studied. Discrimination and calibration of the test were measured by the area under the curve and Hosmer-Lemeshow test. RESULTS: A total of 1685 were included. There were 183/1299 conversions in the VATS group (14.1%) and 27/386 conversions in the RATS group (6.9%). Patients in the RATS group had fewer antiplatelet therapy and peripheral arterial disease. There were more segmentectomies in the VATS group. As for test discrimination, the area under the curve was 0.66 [0.56-0.78] in the RATS group and 0.64 [0.60-0.69] in the VATS group. Regarding the calibration, the Hosmer-Lemeshow test was not significant for both groups but more positive (better calibrated) for the VATS group (P = 0.12) compared to the RATS group (P = 0.08). CONCLUSIONS: The ECS seems applicable for patients operated with RATS, with a correct discrimination but a lower calibration performance for patients operated with VATS. A new score could be developed to specifically anticipate conversion in patients operated on by RATS.

Peripheral location of lung cancer is associated with higher local disease recurrence.

OBJECTIVES: Our goal was to evaluate the association between the distance of the tumour to the visceral pleura and the rate of local recurrence in patients surgically treated for stage pI lung cancer. METHODS: We conducted a single-centre retrospective review of 578 consecutive patients with clinical stage IA lung cancer who underwent a lobectomy or segmentectomy from January 2010 to December 2019. We excluded 107 patients with positive margins, previous lung cancer, neoadjuvant treatment and pathological stage II or higher status or for whom preoperative computed tomography (CT) scans were not available at the time of the study. The distance between the tumour and the closest visceral pleura area (fissure/mediastinum/lateral) was assessed by 2 independent investigators who used preoperative CT scans and multiplanar 3-dimensional reconstructions. An area under the receiver operating characteristic curve analysis was performed to determine the best threshold for the tumour/pleura distance. Then multivariable survival analyses were used to assess the relationship between local recurrence and this threshold in relation to other variables. RESULTS: Local recurrence occurred in 27/471 patients (5.8%). A cut-off value of 5 mm between the tumour and the pleura was determined statistically. In the multivariable analysis, the local recurrence rate was significantly higher in patients with a tumour-to-pleura distance ≤5 mm compared to patients with a tumour-to-pleura distance >5 mm (8.5% vs 2.7%, hazard ratio 3.36, 95% confidence interval: 1.31-8.59, P = 0.012). Subgroup analyses of patients with pIA and tumour size ≤2 cm identified local recurrences in 4/78 patients treated with segmentectomy (5.1%), with a significantly higher occurrence with tumour-to-pleura distances ≤5 mm (11.4% vs 0%, P = 0.037), and in 16/292 patients treated with lobectomy (5.5%) without significant higher occurrence in tumour-to-pleura distances of ≤5 mm (7.7% vs 3.4%, P = 0.13). CONCLUSIONS: The peripheral location of a lung tumour is associated with a higher rate of local recurrence and should be taken into account during preoperative planning when considering segmental versus lobar resection.

Anatomic lung resection after immune checkpoint inhibitors for initially unresectable advanced-staged non-small cell lung cancer: a retrospective cohort analysis.

Background: Patients with initially unresectable advanced non-small cell lung cancer (NSCLC) might experience prolonged responses under immune checkpoint inhibitors (ICIs). In this setting, Multidisciplinary Tumor Board (MTB) seldomly suggest surgical resection of the primary tumor with the ultimate goal to eradicate macroscopic residual disease. Our objective was to report the perioperative outcomes of patients who underwent anatomic lung resection in these infrequent circumstances. Methods: We set a retrospective multicentric single arm study, including all patients with advanced-staged initially unresectable NSCLC (stage IIIB to IVB) who received systemic therapy including ICIs and eventually anatomical resection of the primary tumor in 10 French thoracic surgery units from January 2016 to December 2020. Coprimary endpoints were in-hospital mortality and morbidity. Secondary endpoints were the rate of complete resection of the pulmonary disease, major pathologic response, risk factors associated with post-operative complications, and overall survival. Results: Twenty-one patients (median age 64, female 62%) were included. Eighteen patients (86%) progressed after first line chemotherapy and received second line ICI. The median time between diagnosis and surgery was 22 months [interquartile range (IQR) 18-35 months]. Minimally-invasive approach was used in 10 cases (48%), with half of these requiring conversion to open thoracotomy. Nine patients (43%) presented early post-operative complications, and one patient died from broncho-pleural fistula one month after surgery. Rates of complete resection of the pulmonary disease and major pathologic response were 100% and 43%, respectively. In univariable analysis, diffusing capacity for carbon monoxide (DLCO) was the only factor associated with the occurrence of postoperative complications (P=0.027). After a median follow-up of 16.0 months after surgery (IQR, 12.0-30.0 months), 19 patients (90%) were still alive. Conclusions: Anatomic lung resections appear to be a reasonable option for initially unresectable advanced NSCLC experiencing prolonged response under ICIs. Nonetheless, minimally invasive techniques have a low applicability and post-operative complications remains higher in patients who had lower DLCO values. The late timing of surgery may also contribute to complications.

Rerouting the internal thoracic vessels as recipient vessels in head and neck reconstruction: Comparison of two anatomic approaches.

INTRODUCTION: The vessel-depleted neck situation is a challenge for the surgeon in search of suitable recipient vessels for microvascular reconstruction of the head and neck. The internal thoracic vessels (ITVs) have proven useful as "rescue" recipient vessel resource. The objective of this report is to assess the feasibility of using ITVs by rerouting the pedicle for free flap reconstruction of the head and neck by comparing two different approaches. MATERIAL AND METHODS: Two surgical approaches were assessed: the classical one is parasternal, but cardiac surgeons commonly use median sternotomy. We conducted an anatomical study, comparing on the same subject the lengths and diameters of both internal thoracic artery (ITA) and internal thoracic vein (ITV) at the sixth, fifth, and fourth intercostal spaces (ICSs) through parasternal approach on one side and by median sternotomy on the other side. RESULTS: The study was performed on 13 subjects. We found a superiority of length of the ITVs with the median sternotomy approach. Regarding the mean length of the ITA, the sternotomy approach allowed a significant greater length with 119/89/67 mm, compared with parasternal approach with 91/62/42 mm, respectively at the sixth, fifth, and fourth ICS (p<0.001). Similarly, we observed a significant greater length of the ITV with 116/85/63 mm versus 89/62/42 mm (p<0.001). The mean arterial and venous diameters were 2.9 mm and 2.1 mm in the sixth ICS, 3.3 mm and 2.3 mm in the fifth ICS, and 3.9 mm and 2.9 mm in the fourth ICS, respectively. CONCLUSION: These results help to guide the choice of surgical approach and the level of harvesting.

Patient risk factors for conversion during video-assisted thoracic surgery-the Epithor conversion score.

OBJECTIVES: Intraoperative conversion from video-assisted thoracic surgery (VATS) to thoracotomy may occur during anatomical lung resection. The objectives of the present study were to identify risk factors for intraoperative conversion and to develop a predictive score. METHODS: We performed a multicentre retrospective analysis of French thoracic surgery departments that contributed data on anatomical lung resections to the Epithor database over a 10-year period (from January-2010 to December-2019). Using univariate and multivariate logistic regression analyses, we determined risk factors for intraoperative conversion and elaborated the Epithor conversion score (ECS). The ECS was then validated in a cohort of patients operated on between January- and June-2020. RESULTS: From January-2010 to December-2019, 210,037 patients had been registered in the Epithor database. Of these, 55,030 had undergone anatomical lung resection. We excluded patients who had upfront a thoracotomy or robotic-assisted thoracoscopic surgery (n = 40,293) and those with missing data (6,794). Hence, 7943 patients with intent-to-treat VATS were assessed: 7100 with a full VATS procedure and 843 patients with intraoperative conversion to thoracotomy (conversion rate: 10.6%). Thirteen potential risk factors were identified among patients' preoperative characteristics and planned surgical procedures and were weighted accordingly to give the ECS. The score showed acceptable discriminatory power (area under the curve: 0.62 in the development cohort and 0.64 in the validation cohort) and good calibration (P = 0.23 in the development cohort and 0.30 in the validation cohort). CONCLUSIONS: Thirteen potential preoperative risk factors were identified, enabling us to develop and validate the ECS-an easy-to-use, reproducible tool for estimating the risk of intraoperative conversion during VATS.

Benignant and malignant epidemiology among surgical resections for suspicious solitary lung cancer without preoperative tissue diagnosis.

OBJECTIVES: The aim of this study was to describe the epidemiology of patients undergoing diagnostic and/or curative surgical pulmonary resections for lung opacities suspected of being localized primary lung cancers without preoperative tissue confirmation. METHODS: We performed a single-centre retrospective study of a prospectively implemented institutional database of all patients who underwent pulmonary resection between January 2010 and December 2020. Patients were selected when surgery complied with the Fleischner society guidelines. We performed a multivariable logistic regression to determine the preoperative variables associated with malignancy. RESULTS: Among 1392 patients, 213 (15.3%) had a final diagnosis of benignancy. We quantified futile parenchymal resections in 29 (2.1%) patients defined by an anatomical resection of >2 lung segments for benign lesions that did not modified the clinical management. Compared with patients with malignancies, patients with benignancies were younger (57.5 vs 63.9 years, P < 0.001), had lower preoperative risk profile (thoracoscore 0.4 vs 2.1, P < 0.001), had a higher proportion of wedge resection (50.7% vs 12.2%, P < 0.01) and experienced a lower burden of postoperative complication (Clavien-Dindo IV or V, 0.4% vs 5.6%, P < 0.001). Preoperative independent variables associated with malignancy were (adjusted odd ratio [95% confident interval]) age 1.02 [1.00; 1.04], smoking (year-pack) 1.005 (1.00; 1.01), history of cardiovascular disease 2.06 [1.30; 3.30], history of controlled cancer 2.74 [1.30; 6.88] and clinical N involvement 4.20 [1.11; 37.44]. CONCLUSIONS: Futile parenchymal lung resection for suspicious opacities without preoperative tissue diagnosis is rare (2.1%) while surgery for benign lesions represented 15.3% and has a satisfactory safety profile with very low postoperative morbi-mortality.

Risk Prediction Model of 90-Day Mortality After Esophagectomy for Cancer.

Importance: Ninety-day mortality rates after esophagectomy are an indicator of the quality of surgical oncologic management. Accurate risk prediction based on large data sets may aid patients and surgeons in making informed decisions. Objective: To develop and validate a risk prediction model of death within 90 days after esophagectomy for cancer using the International Esodata Study Group (IESG) database, the largest existing prospective, multicenter cohort reporting standardized postoperative outcomes. Design, Setting, and Participants: In this diagnostic/prognostic study, we performed a retrospective analysis of patients from 39 institutions in 19 countries between January 1, 2015, and December 31, 2019. Patients with esophageal cancer were randomly assigned to development and validation cohorts. A scoring system that predicted death within 90 days based on logistic regression ß coefficients was conducted. A final prognostic score was determined and categorized into homogeneous risk groups that predicted death within 90 days. Calibration and discrimination tests were assessed between cohorts. Exposures: Esophageal resection for cancer of the esophagus and gastroesophageal junction. Main Outcomes and Measures: All-cause postoperative 90-day mortality. Results: A total of 8403 patients (mean [SD] age, 63.6 [9.0] years; 6641 [79.0%] male) were included. The 30-day mortality rate was 2.0% (n = 164), and the 90-day mortality rate was 4.2% (n = 353). Development (n = 4172) and validation (n = 4231) cohorts were randomly assigned. The multiple logistic regression model identified 10 weighted point variables factored into the prognostic score: age, sex, body mass index, performance status, myocardial infarction, connective tissue disease, peripheral vascular disease, liver disease, neoadjuvant treatment, and hospital volume. The prognostic scores were categorized into 5 risk groups: very low risk (score, ≥1; 90-day mortality, 1.8%), low risk (score, 0; 90-day mortality, 3.0%), medium risk (score, -1 to -2; 90-day mortality, 5.8%), high risk (score, -3 to -4: 90-day mortality, 8.9%), and very high risk (score, ≤-5; 90-day mortality, 18.2%). The model was supported by nonsignificance in the Hosmer-Lemeshow test. The discrimination (area under the receiver operating characteristic curve) was 0.68 (95% CI, 0.64-0.72) in the development cohort and 0.64 (95% CI, 0.60-0.69) in the validation cohort. Conclusions and Relevance: In this study, on the basis of preoperative variables, the IESG risk prediction model allowed stratification of an individual patient's risk of death within 90 days after esophagectomy. These data suggest that this model can help in the decision-making process when esophageal cancer surgery is being considered and in informed consent.

Utilization of a training portfolio in thoracic and cardiovascular surgery: the example of the French platform-EPIFORM.

Thoracic and cardiovascular surgery requires learning both theoretical knowledge and technical skills. In this surgical field, several disparities exist between the different training programs around the world. This report describes the implementation of a portfolio in the teaching and assessment of French trainees in Thoracic and Cardiovascular surgery, following an electronic logbook model, aiming to improve the training program. The French surgical course is a twelve semesters' curriculum divided in 3 parts, each part containing knowledge, technical skills and behaviors objectives to be validated, defined by the French College of Thoracic and Cardiovascular surgery. The competencies are marked in the logbook, following a declarative model where the surgical trainee fills every surgical procedure attended (all or part) if he/she has observed, partially or fully performed, or supervised another trainee. All the surgical procedures are linked to theoretical e-learning lessons and each e-learning lesson includes a self-evaluation. This constitutes a competency-based assessment model with milestones both for surgeon trainees and their mentors. This portfolio also contains complementary tools such as an automated publication point calculation, a formatted curriculum vitae generator, and several contact tools between trainees. Implementation of a dedicated portfolio following an electronic logbook model appears to be a relevant pedagogic tool and survey element in the thoracic and cardiovascular surgery training program. Its use may lead to potential educational benefits for the trainee, reliable competency assessment for the supervising surgeon and for scientific society or national college.

Lymphatic drainage of lung cancer follows an intersegmental pathway within the visceral pleura.

OBJECTIVES: Lung cancer tumors are known to be highly lymphophilic. There are two different pattern of lymphatic drainage of the lung: one peribronchial lymphatic pathway, and another one within the visceral pleura which appears to be more intersegmental than the peribronchial pathway. We aimed to assess the prevalence of an intersegmental pathway in the lymphatic drainage of lung tumors within the visceral pleura and determine potential influential factors. METHODS: In this prospective study, we included all patients for whom a major pulmonary resection (lobar) was indicated and performed for suspected or proven lung cancer. An immediate ex-vivo evaluation of the surgical specimen after resection was conducted by trans-pleural injection of blue dye within the tumor. The pathways followed by the lymphatic vessels under the visceral pleura were assessed to define the occurrence of an intersegmental pathway, which was defined by the presence of blue dye within the lymphatic vessel crossing to a neighboring pulmonary segment, distinct from the tumorous segment. RESULTS: Fifty-three patients met the inclusion criteria and were assessed over a three-year period. Lymphatic drainage within the visceral pleura followed an intersegmental pathway in 35 of 53 patients (66 %). When the lymphatic drainage of the tumor was intersegmental, it drained in a single other segment in 21/35 cases and two or more in 14/35 cases. Logistic regression with multivariate analysis showed a peripheral location of the tumor to be a risk factor for the intersegmental pathway of visceral pleura lymphatic drainage (OR = 0.87 [079-0.95], p = 0.003). CONCLUSION: These results confirm that lymphatic drainage of lung cancer in the visceral pleura appears to largely follow an intersegmental pathway, especially when the tumor is peripheral, close to the visceral pleura.

Intraoperative conversion during video-assisted thoracoscopy resection for lung cancer does not alter survival.

OBJECTIVES: The aim of this study was to assess the long-term outcomes of patients treated by anatomical pulmonary resection with the video-assisted thoracoscopic surgery (VATS) approach, VATS requiring intraoperative conversion to thoracotomy or an upfront open thoracotomy for lung cancer surgery. METHODS: We performed a retrospective single-centre study that included consecutive patients between January 2011 and December 2018 treated either by VATS (with or without intraoperative conversion) or open thoracotomy for non-small-cell lung cancer (NSCLC). Patients treated for a benign or metastatic condition, stage IV disease, multiple primary lung cancer or by resection, such as pneumonectomies or angioplastic/bronchoplastic/chest wall resections, were excluded. RESULTS: Among 1431 patients, 846 were included: 439 who underwent full-VATS, 94 who underwent VATS-conversion (21 emergent, 73 non-emergent) and 313 treated with upfront open thoracotomy. The median follow-up was 37 months. There were no statistical differences in stage-specific overall survival between the full-VATS, VATS-conversion, and open thoracotomy groups, with 5-year OS for stage I NSCLC of 76%, 72.3% and 69.4%, respectively (P = 0.47). There was a difference in disease-free survival for stage I NSCLC, with 71%, 60.2% and 53%, respectively at 5 years (P = 0.013). Fewer complications occurred in the full-VATS group (pneumonia, arrhythmia, length of stay), but complication rates were similar between the VATS-conversion and thoracotomy groups. CONCLUSIONS: VATS resection for NSCLC with intraoperative conversion does not appear to alter the long-term oncological outcome relative to full-VATS or open upfront thoracotomy. Postoperative complications were higher than for full-VATS and comparable to those for thoracotomy. VATS should be favoured when possible.

Guidelines on enhanced recovery after pulmonary lobectomy.

OBJECTIVE: To establish recommendations for optimisation of the management of patients undergoing pulmonary lobectomy, particularly Enhanced Recovery After Surgery (ERAS). DESIGN: A consensus committee of 13 experts from the French Society of Anaesthesia and Intensive Care Medicine (Soci,t, franOaise d'anesth,sie et de r,animation, SFAR) and the French Society of Thoracic and Cardiovascular Surgery (Soci,t, franOaise de chirurgie thoracique et cardiovasculaire, SFCTCV) was convened. A formal conflict-of-interest policy was developed at the onset of the process and enforced throughout. The entire guidelines process was conducted independently of any industry funding. The authors were advised to follow the principles of the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system to guide assessment of quality of evidence. METHODS: Five domains were defined: 1) patient pathway and patient information; 2) preoperative management and rehabilitation; 3) anaesthesia and analgesia for lobectomy; 4) surgical strategy for lobectomy; and 5) enhanced recovery after surgery. For each domain, the objective of the recommendations was to address a number of questions formulated according to the PICO model (Population, Intervention, Comparison, Outcome). An extensive literature search on these questions was carried out and analysed using the GRADE® methodology. Recommendations were formulated according to the GRADE® methodology, and were then voted by all experts according to the GRADE grid method. RESULTS: The SFAR/SFCTCV guideline panel provided 32 recommendations on the management of patients undergoing pulmonary lobectomy. After two voting rounds and several amendments, a strong consensus was reached for 31 of the 32 recommendations and a moderate consensus was reached for the last recommendation. Seven of these recommendations present a high level of evidence (GRADE 1+), 23 have a moderate level of evidence (18 GRADE 2+ and 5 GRADE 2-), and 2 correspond to expert opinions. Finally, no recommendation was provided for 2 of the questions. CONCLUSIONS: A strong consensus was expressed by the experts to provide recommendations to optimise the whole perioperative management of patients undergoing pulmonary lobectomy.
