Background: Despite the implementation of Enhanced Recovery After Surgery (ERAS) programs, surgical stress continues to influence postoperative rehabilitation, including the period after discharge. However, there is a lack of data available beyond the point of discharge following video-assisted thoracoscopic surgery (VATS) wedge resection. Therefore, the objective of this study is to investigate incidence and risk factors for readmissions after ERAS VATS wedge resection. Methods: A retrospective analysis was performed on data from prospectively collected consecutive VATS wedge resections from June 2019 to June 2022. We evaluated main reasons related to wedge resection leading to 90-day readmission, early (occurring within 0–30 days postoperatively) and late readmission (occurring within 31–90 days postoperatively). To identify predictors for these readmissions, we utilized a logistic regression model for both univariable and multivariable analyses. Results: A total of 850 patients (non-small cell lung cancer 21.5%, metastasis 44.7%, benign 31.9%, and other lung cancers 1.9%) were included for the final analysis. Median length of stay was 1 day (IQR 1–2). During the postoperative 90 days, 86 patients (10.1%) were readmitted mostly due to pneumonia and pneumothorax. Among the cohort, 66 patients (7.8%) had early readmissions primarily due to pneumothorax and pneumonia, while 27 patients (3.2%) experienced late readmissions mainly due to pneumonia, with 7 (0.8%) patients experiencing both early and late readmissions. Multivariable analysis demonstrated that male gender, pulmonary complications, and neurological complications were associated with readmission. Conclusions: Readmission after VATS wedge resection remains significant despite an optimal ERAS program, with pneumonia and pneumothorax as the dominant reasons. Early readmission was primarily associated with pneumothorax and pneumonia, while late readmission correlated mainly with pneumonia.

Enhanced recovery after surgery programs with median postoperative hospitalization of 2 days improve outcomes after lung cancer surgery. This article explores nursing care practices for patients with lung cancer who remain hospitalized despite having recovered somatically. Qualitative focus group interviews were conducted with 16 nurses. Ricoeur’s phenomenological hermeneutics underpins the methodology applied in this study, and we relied on Benner and Wrubel’s theory. The nurses emphasized that the thoughts of patients with a recent lung cancer diagnosis revolve around more than the surgery. Nursing comprises not only practicalities but also attending to patients’ stress and their coping with being struck with lung cancer and having undergone surgery. A counterculture emerged to counteract the logic of productivity, indicating that caring as a worthy end in itself may be underestimated in protocol-driven care. Prolonging hospitalization largely depends on clinical judgment. The nurses’ aim is not to keep patients in the hospital but to avoid any needless suffering, allowing them to reclaim the primacy of caring.

Atypical carcinoid (AC) is a rare neuroendocrine neoplasm of the lung, which exhibits a varying malignant potential. In this study, we aimed to identify the prognostic thresholds of the mitotic count and Ki-67 labeling index for recurrence and survival in AC. We retrospectively reviewed 78 patients who had been radically resected for AC and calculated said thresholds using time-dependent receiver operating characteristic curves and the Youden index. We then dichotomized the patients into groups of above or below these thresholds and estimated the cumulative incidences of the groups using the Aalen-Johansen estimator. We compared the groups using univariable and multivariable Fine-Gray subdistribution hazard models. Our findings show that more patients recurred and died from this disease if their mitotic count exceeded three and four mitoses per 2 mm 2, respectively, or if their Ki-67 labeling index exceeded 14% and 11%, respectively. Both thresholds independently predicted survival ( p < 0.001 and p = 0.015, respectively). These thresholds may serve as a valuable tool for clinicians and researchers in making treatment plans and predicting outcomes for patients with AC.

Objectives Lung volume reduction surgery (LVRS) has proven an effective treatment for emphysema, by decreasing hyperinflation and improving lung function, activity level and reducing dyspnoea. However, postoperative air leak is an important complication, often leading to reoperation. Our aim was to analyse reoperations after LVRS and identify potential predictors. Methods Consecutive single-centre unilateral VATS LVRS performed from 2017 to 2022 were included. Typically, 3–5 minor resections were made using vascular magazines without buttressing. Data were obtained from an institutional database and analysed. Multivariable logistic regression was used to identify predictors of reoperation. Number and location of injuries were registered. Results In total, 191 patients were included, 25 were reoperated (13%). In 21 patients, the indication for reoperation was substantial air leak, 3 patients bleeding and 1 patient empyema. Length of stay (LOS) was 21 (11–33) vs. 5 days (3–11), respectively. Only 3 injuries were in the stapler line, 13 within < 2cm and 15 injuries were in another site. Multivariable logistic regression analysis showed that decreasing DLCO increased risk of reoperation, OR 1.1 (1.03, 1.18, P = 0.005). Resections in only one lobe, compared to resections in multiple lobes, were also a risk factor OR 3.10 (1.17, 9.32, P = 0.03). Patients undergoing reoperation had significantly increased 30-day mortality, OR 5.52 (1.03, 26.69, P = 0.02). Conclusions Our incidence of reoperation after LVRS was 13% leading to prolonged LOS and increased 30-day mortality. Low DLCO and resections in a single lobe were significant predictors of reoperation. The air leak was usually not localized in the stapler line., Objectives: Lung volume reduction surgery (LVRS) has proven an effective treatment for emphysema, by decreasing hyperinflation and improving lung function, activity level and reducing dyspnoea.

Heart rate variability (HRV) is a measure of cardiac autonomic modulation and is potentially related to hypotension, postoperative atrial fibrillation, and orthostatic intolerance. However, there is a lack of knowledge on which specific time points and indices to measure. To improve future study design, there is a need for procedure-specific studies in an enhanced recovery after surgery (ERAS) video-assisted thoracic surgery (VATS) lobectomy setting, and for continuous measurement of perioperative HRV. HRV was measured continuously from 2 days before until 9 days after VATS lobectomy in 28 patients. After VATS lobectomy, with median length of stay = 4 days, the standard deviation between normal-to-normal beats and the total power of HRV were reduced for 8 days during the night and day times, while low-to-high frequency variation and detrended fluctuation analysis were stable. This is the first detailed study to show that HRV measures of total variability were reduced following ERAS VATS lobectomy, while other measures were more stable. Further, preoperative HRV measures showed circadian variation. The patch was well tolerated among participants, but actions should be taken to ensure proper mounting of the measuring device. These results demonstrate a valid design platform for future HRV studies in relation to postoperative outcomes., Heart rate variability (HRV) is a measure of cardiac autonomic modulation and is potentially related to hypotension, postoperative atrial fibrillation, and orthostatic intolerance.

Aims and Objectives: To gain insight into nursing in an enhanced recovery after surgery program for lung cancer, we explored its meaning for nurses in a thoracic surgery unit. Background: Since nurses play a key role in overcoming implementation barriers in enhanced recovery after surgery programs, successful implementation depends on their care approach during the surgery pathway. Design: Qualitative focus group study. Methods: A hermeneutic approach inspired by Gadamer guided the research. Sixteen thoracic surgery nurses participated in focus group interviews. Benner and Wrubel's primacy of caring theory enhanced understanding of the findings. COREQ guidelines were followed. Results: The thoracic surgery nurses compared the streamlined trajectory in the program to working in a factory. Shifting focus away from a dialogue-based, situated care practice compromised their professional nursing identity. The program made combining scientific evidence with patients' lifeworld perspectives challenging. Although the nurses recognised that the physiological processes and positive outcomes promoted recovery, they felt each patient's life situation was not sufficiently considered. To meet the program's professional nursing responsibilities and provide comprehensive care, specialised thoracic nursing should continue after discharge to allow professional care while meaningfully engaging with the patient's situatedness and lifeworld. Conclusions: Primacy of caring risks being compromised if accelerated treatment is implemented uncritically. If care is based on the dominant rational justifications underpinning surgical nursing, living conditions and patient values might be overlooked, affecting how disease, illness and health are managed. Relevance to Clinical Practice: Our findings focus on obvious unintended consequences of enhanced recovery after surgery programs. To avoid dehumanising patients, surgical lung cancer programs must adopt a humanistic attitude in a caring prac

This review summarizes key recent developments relevant to the surgical management of lung neuroendocrine neoplasms (L-NENs), including typical and atypical carcinoids, large cell neuroendocrine carcinoma, and small cell lung carcinoma. This review includes recent insights into the classification, clinical presentation, diagnostic workup, treatment options, and follow-up. Highlighted topics include general principles of surgery in localized or locally advanced or metastatic L-NENs, lung-sparing surgery for small, peripheral typical carcinoids, adjuvant and systemic therapies for typical and atypical carcinoids, and surgery and adjuvant therapies for large cell neuroendocrine carcinoma and small cell lung carcinoma.

Pulmonary sequestration is a rare congenital abnormality that requires surgical resection if symptomatic. The pulmonary sequestration can be extra lobar with a separate visceral pleura, artery and venous drainage or intra lobar contained within the visceral pleura of the lung with a separate artery and venous drainage to the pulmonary vein. Rarely the entire lobe is affected in intra lobar sequestration and segmentectomy should be considered rather than lobectomy. A case of an intra lobar sequestration in the left lower lobe with a feeding artery coming from the descending thoracic aorta is presented. The patient was a young woman, who had experienced recurrent pneumonia for one year. A left video-assisted thoracoscopic surgery (VATS) basilar segmentectomy was performed using a standardized anterior threeport approach. Due to the recurrent infections, the hilar lymph nodes were fibrotic, and dissection was performed using an advanced energy system. Identification of the intersegmental plane may be challenging in segmentectomies. Most surgeons use an inflation-deflation technique. In this case identification was performed using a near-infra red camera and intravenous injection of indocyanine green. Identification was successful. The postoperative course was uneventful with a length of stay of two days. On follow up 6 months postoperatively, the patient was without any symptoms

Background: There is growing evidence that misdiagnosis contributes to the high mortality rate in lung cancer patients complicated with pulmonary embolism (PE). This current study analyzed predictors of PE in lung cancer patients with lower extremity deep venous thrombosis (DVT) with the aim of personalizing the treatment and management of patients with PE. Methods: This retrospective case-control study included lung cancer patients with DVT at the emergency department of Shanghai Chest Hospital from January 2018 to December 2019. Patients were classified as having DVT with or without PE. The following characteristics were examined, including age, gender, smoking, hypertension, surgical trauma, hyperlipidemia, long-term bedridden status, calf swelling, coronary heart disease, chronic pulmonary disease, DVT location, DVT type, prothrombin time (PT), international normalized ratio (INR), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen, and D-dimer, and univariate and multivariate analyses were performed. Results: A total of 90 patients with lung cancer and DVT were analyzed, of whom 60% (54/90) had PE. Those variables independently associated to PE were hypertension [odds ratio (OR): 7.883, 95% confidence interval (CI): 2.038–30.495, P=0.003], long-term bedridden status (OR: 4.166, 95% CI: 1.236–14.044, P=0.021), and D-dimer levels (OR: 2.123, 95% CI: 1.476–3.053, P=0.000) were identified as independent risk factors for PE. The cut-off value of the receiver operating characteristic (ROC) curve for predicting PE by presented scoring system according to the risk factors was 1.5 and the area under the curve (AUC) was 0.84 (P<0.001). Conclusions: Hypertension, being bedridden for an extended period, and elevated serum D-dimer levels were independent risk factors of PE in lung cancer patients with lower extremity DVT. Novel strategies for patient management should be developed to decrease the risk of PE.

Background: Days alive and out of hospital is proposed as a valid and patient-centred quality measure for perioperative care. However, no procedure-specific data exist after pulmonary wedge resection. The aim of this study was to assess the first 90 days alive and out of hospital after video-assisted thoracoscopic surgery wedge resection in an optimized enhanced recovery programme. Methods: A retrospective analysis of prospectively collected data of consecutive patients undergoing enhanced recovery thoracoscopic wedge resections from January 2021 to June 2022 in a high-volume centre was carried out. All factors leading to hospitalization, readmission, and death were evaluated individually. A logistic regression model was used to evaluate predictors. Additionally, a sensitivity analysis was performed. Results: A total of 433 patients were included (21.7% (n = 94) with non-small cell lung cancer, 47.6% (n = 206) with metastasis, 26.8% (n = 116) with benign nodules, and 3.9% (n = 17) with other lung cancers). The median duration of hospital stay was 1 day. The median of postoperative 30 and 90 days alive and out of hospital was 28 and 88 days respectively. Air leak (112 patients) and pain (96 patients) were the most frequent reasons for reduced days alive and out of hospital from postoperative day 1 to 30, whereas treatment of the original cancer or metastasis (36 patients) was the most frequent reason for reduced days alive and out of hospital from postoperative day 31 to 90. Male sex, reduced lung function, longer dimension of resection margin, pleural adhesions, and non-small cell lung cancer were independent risks, confirmed by a sensitivity analysis. Conclusion: Days alive and out of hospital within 90 days after enhanced recovery thoracoscopic wedge resection was only reduced by a median of 2 days, mainly due to air leak and pain.

We sought to investigate whether video-assisted thoracicsurgery (VATS) or thoracotomy provides the best outcomes in the treatment of stage II and III pleuralinfection as indications remain controversial.Methods: Systematic review of relevant articles from the PubMed database.Key Content and Findings: Nine non-randomized retrospective studies published between 1996and 2020 with a total of 2,121 patients were included. Results varied between studies, but overall shorteroperative and recovery times and greater patient satisfaction were demonstrated using VATS compared withthoracotomy.Conclusions: Although VATS and thoracotomy are viable treatment options for stage II and III pleuralinfection, VATS has potential advantages in terms of decreased operation time, fewer days with tubedrainage, shorter postoperative hospital stay, reduced postoperative pain, increased patient satisfactionwith the procedure, and wound appearance. VATS has limitations in the treatment of patients with stageIII pleural infection, where delayed surgical referral has been shown to increase the risk of intraoperativeconversion to thoracotomy. The data to date implies that debridement by VATS should be proposed as soonas possible in stage II pleural infection and considered in cases of stage, Background and Objective: Pleural infection is associated with significant mortality and morbidity worldwide, with a steadily increasing incidence.

Pulmonary nodules are often encountered by respiratory physicians, radiologists and thoracic surgeons alike. The European Association of Cardio-Thoracic Surgery and the European Society of Thoracic Surgeons established a multidisciplinary collaboration of clinicians (task force) with expertise in managing pulmonary nodules with the aim of producing the first joint comprehensive review of the scientific literature, with a specific focus on the management of pure ground-glass opacities and part-solid nodules. The scope of the document has been defined by the European Association of Cardio-Thoracic Surgery and European Society of Thoracic Surgeons governing bodies and focuses on 6 main areas of interest agreed upon by the task force. These include managing solitary and multiple pure ground-glass nodules and solitary part-solid nodules and identifying the non-palpable lesion, the role of minimally invasive surgery and the decision making behind sublobar versus lobar resection. The literature revealed that, with the increasing use of incidental computed tomography scans and computed tomography lung cancer screening programmes, the detection of early-stage lung cancer is going to increase, with a higher number of potential cancers presenting on the ground-glass and part-solid nodule spectrum. Given that the gold standard for improved survival is surgical resection, there is an urgent need for comprehensive characterization of these nodules and for guidelines that are directed towards their surgical management. It is recommended that standard decision-making tools be used to determine the risk of malignancy and thus guide referral for surgical management and that decisions for surgical resection be made in a multidisciplinary setting with equitable consideration given to radiologic characteristics, the evolution of the lesion, the presence of a solid component, patient fitness and patient co-morbidities. Given the recent surge in robust level I data compa

OBJECTIVES To identify and prioritize technical procedures for simulation-based training to be integrated into the thoracic surgical curriculum. METHODS A 3-round Delphi survey was conducted from February 2022 to June 2022 among 34 key opinion leaders in thoracic surgery from 14 countries worldwide. The 1st round was a brainstorming phase to identify technical procedures that a newly qualified thoracic surgeon should be able to perform. All the suggested procedures were categorized, qualitatively analysed and sent to the 2nd round. The second round investigated: the frequency of the identified procedure at each institution, the number of thoracic surgeons that should be able to perform these procedures, the degree of risk to the patient if the procedure is performed by a non-competent thoracic surgeon and the feasibility of simulation-based education. In the 3rd round, elimination and re-ranking of the procedures from the 2nd round were performed. RESULTS Response rates in the 3 iterative rounds were 80% (28 out of 34), 89% (25 out of 28) and 100% (25 out of 25) in the 1st, 2nd and 3rd round, respectively. Seventeen technical procedures were included for simulation-based training in the final prioritized list. The top 5 procedures were Video-Assisted Thoracoscopic Surgery (VATS) lobectomy, VATS segmentectomy, VATS mediastinal lymph node dissection, diagnostic flexible bronchoscopy and robotic-assisted thoracic surgery port placement, robotic-assisted thoracic surgery docking and undocking. CONCLUSIONS The prioritized list of procedures represents a consensus of key thoracic surgeons worldwide. These procedures are suitable for simulation-based training and should be integrated in the thoracic surgical curriculum., OBJECTIVES: To identify and prioritize technical procedures for simulation-based training to be integrated into the thoracic surgical curriculum.

This report presents the case of a woman successfully treated with thoracoscopic detorsion of the right lung after she was diagnosed with a 180-degree torsion, 6 months after a video-assisted thoracoscopic right upper lobectomy for a stage 1 adenocarcinoma.

The potential complications related to unplanned conversion to thoracotomy remains a major concern in thoracoscopic lobectomy and may limit the wide adoption of this strategy. We reviewed the literature from 1990 until February 2022, analyzing all papers comparing successful thoracoscopic lobectomy versus converted thoracoscopic lobectomy and/or upfront thoracotomy lobectomy to establish whether unplanned conversion negatively affected outcomes. Thirteen studies provided the most applicable evidence to evaluate this issue. Conversion to thoracotomy was reported to occur in up to 23% of cases (range, 5%–16%). Vascular injury, calcified lymph nodes, and dense adhesions were the most common reasons for conversion. Converted thoracoscopic lobectomy compared to successful thoracoscopic lobectomy was associated with longer operative time and hospital stay in all studies, with higher postoperative complication rates in seven studies, and with higher perioperative mortality rates in four studies. No significant differences were found between converted thoracoscopic lobectomy and upfront thoracotomy lobectomy. Five studies evaluated long-term survival, and in all papers conversion did not prejudice survival. Surgeons should not fear unplanned conversion during thoracoscopic lobectomy, but to avoid unexpected conversion that may negatively impact surgical outcome, a careful selection of patients is recommended–especially for frail patients.

AIM: The aim of this study is to develop a reliable composite score based on simulator metrics to assess competency in virtual reality video-assisted thoracoscopic surgery lobectomy and explore the benefits of combining it with expert rater assessments. METHODS: Standardized objective assessments (time, bleeding, economy of movement) and subjective expert rater assessments from 2 previous studies were combined. A linear mixed model including experience level, lobe and the number of previous simulated procedures was applied for the repeated measurements. Reliability for each of the 4 assessments was calculated using Cronbach's alpha. The Nelder-Mead numerical optimization algorithm was used for optimal weighting of scores. A pass-fail standard for the composite score was determined using the contrasting groups' method. RESULTS: In total, 123 virtual reality video-assisted thoracoscopic surgery lobectomies were included. Across the 4 different assessments, there were significant effects (P < 0.01) of experience, lobe, and simulator experience, but not for simulator attempts on bleeding (P = 0.98). The left upper lobe was significantly more difficult compared to other lobes (P = 0.02). A maximum reliability of 0.92 could be achieved by combining the standardized simulator metrics with standardized expert rater scores. The pass/fail level for the composite score when including 1 expert rater was 0.33. CONCLUSIONS: Combining simulator metrics with 1 or 2 raters increases reliability and can serve as a more objective method for assessing surgical trainees. The composite score may be used to implement a standardized and feasible simulation-based mastery training program in video-assisted thoracoscopic surgery lobectomy.

OBJECTIVES: Days alive and out of hospital (DAOH) integrates overall information of hospitalization, readmissions, and mortality that have been applied as a new outcome measure. However, DAOH after video-assisted thoracoscopic surgery (VATS) in an established enhanced recovery after surgery (ERAS) programme has not been reported. METHODS: Patients aged ≥18 years with non-small-cell lung cancer undergoing VATS lobectomy in an established ERAS programme were eligible. The primary and secondary outcomes were DAOH during the first postoperative 365 days and reasons for reduced DAOH. RESULTS: A total of 316 consecutive patients with well-defined inclusion criteria and complete follow-up were assessed retrospectively. The median length of stay was 3 days (IQR 2-6). The medians (IQR) of postoperative 30, 60, 90, 180 and 365 DAOH were 27 (22-28), 57 (51-58), 86 (80-88), 176 (169-178) and 359 (349-363) days, respectively. Air leak was the dominant factor for reduced DAOH from postoperative day (POD) 0-30 (47.2%) and 0-365 (38.3%). Side effects of adjuvant chemotherapy were dominant from POD 31-60 and 61-90 (23.5% and 47.1%) and recurrence/metastases from POD 91-180 and 181-365 (25.6% and 50.0%). A low diffusing capacity for carbon monoxide (odds ratios 1.28, 95% confidence interval 1.07-1.53; P=0.007) and prior surgical history (odds ratios 1.80, 95% confidence interval 1.08-2.99; P=0.023) were predictors for low DAOH. CONCLUSIONS: DAOH after 1 year with an established VATS lobectomy ERAS programme was only reduced with a median of 6 days. The main factors reducing DAOH were air leak, adjuvant chemotherapy and recurrence. DAOH may be an important patient-centred outcome to define future improvement strategies.

Objectives: To determine the number of procedures and expert raters necessary to provide a reliable assessment of competence in Video-Assisted Thoracoscopic Surgery (VATS) lobectomy. Methods: Three randomly selected VATS lobectomies were performed on a virtual reality simulator by participants with varying experience in VATS. Video recordings of the procedures were independently rated by three blinded VATS experts using a modified VATS lobectomy assessment tool (VATSAT). The unitary framework of validity was used to describe validity evidence, and generalizability theory was used to explore the reliability of different assessment options. Results: Forty-one participants (22 novices, 10 intermediates, and 9 experienced) performed a total of 123 lobectomies. Internal consistency reliability, inter-rater reliability, and test–retest reliability were 0.94, 0.85, and 0.90, respectively. Generalizability theory found that a minimum of two procedures and four raters or three procedures and three raters were needed to ensure the overall reliability of 0.8. ANOVA showed significant differences in test scores between the three groups (P < 0.001). A pass/fail level of 19 out of 25 points was established using the contrasting groups’ standard setting method, leaving one false positive (one novice passed) and zero false negatives (all experienced passed). Conclusion: We demonstrated validity evidence for a VR simulator test with different lung lobes, and a credible pass/fail level was identified. Our results can be used to implement a standardized mastery learning training program for trainees in VATS lobectomies that ensures that everyone reaches basic competency before performing supervised operations on patients.

BACKGROUND: Despite implementation of enhanced recovery after surgery (ERAS) in lung surgery, potential barriers for improvements should be identified. The aim of this single-centre, prospective ERAS cohort study was to explore reasons for delayed patient discharge after video-assisted thoracoscopic surgery (VATS) lobectomy with a median length of hospital stay (LOS) of 2 days. METHODS: Consecutive patients referred for VATS lobectomy were consulted twice daily by an investigator for the primary reasons for continued hospitalization. The secondary outcomes were risk factors for delayed recovery using univariate and multivariate regression analyses. RESULTS: A total of 147 patients were included (69 with LOS more than 2 days and 78 with LOS of 2 days or less) from April 2020 to December 2020. Air leak (27.7 per cent), pneumonia (20.2 per cent), pain (15.3 per cent), urinary/renal factors (11.0 per cent), atrial fibrillation (7.0 per cent), respiratory failure (4.5 per cent), cognitive factors/delirium (4.3 per cent), gastrointestinal factors (3.8 per cent), oxygen dependency (2.7 per cent), social factors (2.0 per cent), and pleural effusion (1.4 per cent) were important factors for discharge more than 2 days after surgery. The 30-day readmission rate after discharge was 21 per cent for LOS of 2 days or less and 22 per cent for LOS more than 2 days (P = 0.856). On a multivariate regression model, age (per 5-year increase, odds ratio (OR) 1.29, 95 per cent c.i. 1.01 to 1.66, P = 0.043) and forced expiratory volume in 1 s (FEV1) per cent (per 5 per cent increase, OR 0.89, 95 per cent c.i. 0.81 to 0.98, P = 0.021) were significantly related to discharge after more than 2 days. CONCLUSION: Despite a short median LOS of 2 days, air leak, pneumonia, and pain remain the most important challenges for further improvement of the ERAS programme. Age and FEV1 per cent were statistically significant risk factors for LOS longer than 2 days.

OBJECTIVES: The purpose of this study was to describe the incidence of and reasons for early (0-30 days) and late (31-90 days) readmissions after enhanced recovery video-assisted thoracoscopic surgery lobectomy. METHODS: We performed a retrospective analysis of prospectively collected consecutive VATS lobectomy data in an institutional database from January 2019 through December 2020. All reasons for readmission with complete follow-up were individually evaluated. Univariable and multivariable analyses were used to assess predictors. RESULTS: In total, 508 patients were included; the median length of stay after the operation was 3 days. There were 77 (15%) early and 54 (11%) late readmissions, respectively. There were 33 (7%) multiple readmissions during postoperative days 0-90; pneumonia (19.8%) and pneumothorax (18.3%) were the dominant reasons for early readmissions, and the side effects of adjuvant chemotherapy (22.0%), for late readmissions. In multivariable analyses, current smoking (P = 0.001), alcohol abuse (P = 0.024) and chronic obstructive pulmonary disease (P = 0.019) were predictors of early readmissions, whereas Clavien-Dindo I-II grade gastrointestinal complications predicted late readmissions (P = 0.006) and multiple readmissions (P = 0.007). Early discharge (< 3 days) was not a predictor of readmissions. Early readmission did not increase late readmission. CONCLUSIONS: Early and late readmissions after video-assisted thoracoscopic lobectomy are frequent even when enhanced recovery programmes are followed. Pulmonary complications and adjuvant chemotherapy are the most predominant reasons for early and late readmissions.

Background: Pulmonary large-cell neuroendocrine carcinoma (LCNEC) is a rare subtype of lung cancer with dismal prognosis. Long-term outcomes after primarily video-assisted thoracoscopic surgery (VATS) have not yet been described in LCNEC. This study aims to determine overall survival and recurrence-free survival after VATS as well as to identify prognostic factors for survival and recurrence. Methods: Data were obtained from a prospective institutional database. Kaplan-Meier estimates of overall survival and recurrence-free survival were determined and compared across prognostic factors using log-rank analysis and the Cox proportional hazards model. Results: Data from 82 consecutive patients undergoing surgical resection from 2009 to 2020 were included. All patients underwent surgical resection with curative intent, of whom 96.3% were by a VATS approach. Morbidity was low without any conversions or 30-day mortality. Lobectomy was performed in 87.8% of patients, followed by wedge resection in 4.9% and segmentectomy in 3.7%. No pneumonectomies were performed. Radical resection (R0) was achieved in 97.6%. Thirty-four patients (41.5%) had adjuvant platinum-based chemotherapy and high proportion completed at least four series (76.7%). The mean follow-up was 5.1 years. The 1-year, 3-year, and 5-year overall survival rates were 86%, 54%, and 45%, while the corresponding recurrence-free survival rates were 67%, 45%, and 35%. Advanced age was an independent predictor of poor overall survival (HR 2.08; 95% CI 1.04–4.17; p = 0.038). Conclusion: A 96.3% VATS rate was feasible in LCNEC and associated with a low morbidity rate and a high compliance with adjuvant chemotherapy. Overall survival and recurrence-free survival was comparable to previous series using thoracotomy.

INTRODUCTION: Use of neoadjuvant immunotherapy agent in advanced stage NSCLC is controversial. Herein, we aim to report on a case series of successful conversion from initial unresectable stage cIIIB NSCLC to radical minimally invasive surgery through immunochemotherapy; with particular attention given to surgical outcomes and survival benefit of surgery.METHODS: Fifty-one patients with initial stage cIIIB NSCLC who received PD-1 agents plus platinum-based chemotherapy between May, 2018 to August, 2020 were retrospectively identified. Surgical and oncological outcomes of enrolled patients were collected.RESULTS: Of 31 patients who underwent subsequent resection, 23 (74.2%) patients underwent lobectomy, 1 (3.2%) underwent pneumonectomy, 5 (16.1%) underwent sleeve lobectomy, and 2 (6.5%) with bilobectomy. The median surgical time was 205 minutes (range, 100-520). The average blood loss was 185 (range: 10-1100) ml. Dense adhesions or fibrosis was noted in 15 cases. The median postoperative hospital stay was 6 (range: 3-13) days. No surgical-related mortality was recorded, only 5 patients (16.1%) experienced any postoperative morbidity (no grade 3 complications). Ten patients (32.3%) had major pathological response, with mediastinal down-staging been observed in 22/31 (71.0%) patients. With a median after up of 15.4 months, thirty-one patients that had surgery had relatively longer median DFS/PFS compared to that of either non-responders or responders that without surgery (27.5 vs. 4.7 vs. 16.7 months, respectively).CONCLUSIONS: Radical surgery after chemoimmunotherapy in initial unresectable stage IIIB NSCLC seems to be safe with low surgical-related mortality and morbidity, and was favorably associated with longer DFS/PFS compared to those without surgery.

Background: The aim of this systematic review and meta-analysis was to determine the efficacy and safety of omitting chest drains compared to routine chest drain placement after video-assisted thoracoscopic surgery (VATS). Methods: Five bibliographic databases, ClinicalTrials.gov and PROSPERO were comprehensively searched from inception to July 29, 2020 (no language restrictions). Postoperative outcomes were extracted and synthesized complying with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Risk of bias (RoB) including non-reporting bias, heterogeneity, and sensitivity were assessed. Subgroup analyses were performed based on study design. Results: Of 7,166 identified studies, 10 studies [four randomized controlled trials (RCTs) and six non-RCTs] with 1,079 patients were included. There were 561 patients in the no chest drain group (NCD) and 518 patients in the standard chest drain group (CD). In pairwise analysis the NCD group had significant shorter length of stay (LOS) [weighted mean difference (WMD) -1.53 days, P<0.001], less postoperative pain scores (WMD -1.09, P=0.002), but higher risk of drain insertion or thoracocentesis [risk radio (RR) 3.02, P=0.040]. There were no significant differences on the incidence of minor pneumothorax (RR 1.77, P=0.128), minor pleural effusion (RR 1.88, P=0.219), minor subcutaneous emphysema (RR 1.37, P=0.427) or pneumonia (RR 0.53, P=0.549). No mortality was observed in either group during the observation period (in-hospital or 30-day mortality). Conclusions: Omitting chest drains in selected patients after VATS seems effective leading to enhanced recovery with shorter length of postoperative stay and less pain but with a higher risk of drain insertion or thoracocentesis. However, a major part of the evidence comes from observational studies with high RoB. Further RCTs are needed to improve the current evidence.

Background: The reporting of surgical techniques is of mixed quality, with most at a very minimal level. Reporting guidelines that could be applied to guide surgical technique reporting vary in methodology for development, discipline coverage, dimension coverage and detail requested. However, a scoping review that could indicate the gaps and efforts needed in surgical technique reporting guidelines is lacking and warranted. This study aims to design a methodological rigour protocol to guide the development of a scoping review of surgical technique reporting guidelines.Methods: This protocol is designed following the 2020 manual proposed by the Joanna Briggs Institute. To further ensure the soundness of the protocol, we also included multidisciplinary professionals (including methodologists, clinicians, and journal editors) to refine the protocol.Discussion: Seven key steps for developing the scoping review are identified and presented in detail, including (I) identifying the research questions; (II) inclusion criteria; (III) search strategy; (IV) source of evidence selection; (V) data extraction; (VI) analysis of the evidence; and (VII) presentation of the results. Guided by this protocol, the subsequent scoping review will inform us the overview of surgical technique reporting guidelines and precisely guide our direction and next steps in improving surgical technique reporting guidelines.Trial registration: This protocol is not registered as the PROSPERO database only accepts registration of systematic review protocols while does not accept registration of scoping review protocols.

BACKGROUND: Minimally invasive surgery combined with enhanced recovery programmes has improved outcomes after lung cancer surgery and where early mobilisation may be an important factor. However, little is known about pulmonary function and oxygenation during mobilisation after video-assisted pulmonary lobectomy. The aim of this prospective pilot cohort study was to explore the effect of postural changes (from supine to sitting to standing) on pulmonary function and oxygen saturation in a well-defined enhanced recovery programmes setting after video-assisted thoracoscopic surgery lobectomy.METHODS: A total of 24 patients were evaluated daily for postoperative pain score, pulmonary function (forced expiratory volume 1 s) and oxygen saturation in supine, sitting and standing position from 6 h after surgery to 6 h after chest drain removal.RESULTS: Mobilisation from supine to standing position showed a significant 7.9% increase (p = 0.04) in forced expiratory volume in 1 s percentage and oxygen saturation about 1.8% (p< 0.001) without increasing pain (p = 0.809).CONCLUSIONS: Early mobilisation should be encouraged to enhance recovery after video-assisted thoracoscopic surgery lobectomy by increasing lung function and oxygen delivery.TRIAL REGISTRATION: • Name of the registry: clinicaltrials.gov • Trial registration number: NCT04508270 • Date of registration: August 11, 2020.
