Opioid-Free Using Ketamine versus Opioid-Sparing Anesthesia during the Intraoperative Period in Video-Assisted Thoracoscopic Surgery: A Randomized Controlled Trial.

Opioids effectively manage perioperative pain but have numerous adverse effects. Opioid-free anesthesia (OFA) eliminates intraoperative opioid use; however, evidence for its use in video-assisted thoracoscopic surgery (VATS) is limited. This study assessed the effect of OFA using ketamine in VATS patients compared to opioid-sparing anesthesia (OSA). A total of 91 patients undergoing VATS lobectomy or segmentectomy were randomized to either the OFA group (ketamine) or the OSA group (remifentanil). The primary outcome was the quality of recovery (QoR) on postoperative day (POD) 1, measured with the QoR-40 questionnaire. Secondary outcomes included postoperative pain scores and adverse events. Both groups had comparable baseline and surgical characteristics. On POD 1, the QoR-40 score was higher in the OFA group than in the OSA group (164.3 ± 10.8 vs. 158.7 ± 10.6; mean difference: 5.6, 95% CI: 1.1, 10.0; p = 0.015), though this did not meet the pre-specified minimal clinically important difference of 6.3. The visual analog scale score was lower in the OFA group as compared to the OSA group at 0-1 h (4.2 ± 2.3 vs. 6.2 ± 2.1; p < 0.001) and 1-4 h after surgery (3.4 ± 1.8 vs. 4.6 ± 1.9; p = 0.003). The OFA group had a lower incidence of PONV (2 [4.4%] vs. 9 [19.6%]; p = 0.049) and postoperative shivering (4 [8.9%] vs. 13 [28.3%]; p = 0.030) than the OSA group at 0-1 h after surgery. Using OFA with ketamine proved feasible, as indicated by the stable intraoperative hemodynamics and absence of intraoperative awareness. Patients undergoing VATS with OFA using ketamine showed a statistically significant, but clinically insignificant, QoR improvement compared to those receiving OSA with remifentanil.

Intercostal Catheters Reduce Long-Term Pain and Postoperative Opioid Consumption after VATS.

Background/Objectives: Pain after video-assisted thoracoscopic surgery (VATS) leads to impaired postoperative recovery, possible side effects of opioid usage, and higher rates of chronic post-surgery pain (CPSP). Nevertheless, guidelines on perioperative pain management for VATS patients are lacking. The aim of this study was to analyze the effectiveness of intercostal catheters in combination with a single shot intraoperative intercostal nerve block (SSINB) in comparison to SSINB alone with respect to opioid consumption and CPSP. Methods: Patients receiving an anatomic VATS resection between 2019 and 2022 for primary lung cancer were retrospectively analyzed. A total of 75 consecutive patients receiving an ICC and SSINB and 75 consecutive patients receiving only SSINB were included in our database. After enforcing the exclusion criteria (insufficient documentation, external follow-ups, or patients receiving opioids on a fixed schedule; n = 9) 141 patients remained for further analysis. Results: The ICC and No ICC cohort were comparable in age, gender distribution, tumor location and hospital stay. Patients in the ICC cohort showed significantly less opioid usage regarding the extent (4.48 ± 6.69 SD vs. 7.23 ± 7.55 SD mg, p = 0.023), duration (0.76 ± 0.97 SD vs. 1.26 ± 1.33 SD days, p = 0.012) and frequency (0.90 ± 1.34 SD vs. 1.45 ± 1.51 SD times, p = 0.023) in comparison to the No ICC group. During the first nine months of oncological follow-up assessments, no statistical difference was found in the rate of patients experiencing postoperative pain, although a trend towards less pain in the ICC cohort was found. One year after surgery, the ICC cohort expressed significantly less often pain (1.5 vs. 10.8%, p = 0.035). Conclusions: Placement of an ICC provides VATS patients with improved postoperative pain relief resulting in a reduced frequency of required opioid administration, less days with opioids, and a reduced total amount of opioids consumed. Furthermore, ICC patients have significantly lower rates of CPSP one year after surgery.

Robotic Versus Thoracoscopic Sub-lobar Resection for Octogenarians with Clinical Stage IA Non-small Cell Lung Cancer: A Propensity Score-Matched Real-World Study.

Minimally invasive sub-lobectomy is sufficient in treating small early-stage non-small cell lung cancer (NSCLC). However, comparison of the feasibility and oncologic efficacy between robot-assisted thoracoscopic surgery (RATS) and video-assisted thoracoscopic surgery (VATS) in performing sub-lobectomy for early-stage NSCLC patients age 80 years or older is scarce. Octogenarians with clinical stage IA NSCLC (tumor size, ≤2 cm) undergoing minimally invasive wedge resection or segmentectomy at Shanghai Chest Hospital from 2011 to 2020 were retrospectively reviewed from a prospectively maintained database. Propensity score-matching (PSM) with a RATS versus VATS ratio of 1:4 was performed. Perioperative and long-term outcomes were analyzed. The study identified 594 patients (48 RATS and 546 VATS patients), and PSM resulted in 45 cases in the RATS group and 180 cases in the VATS group. The RATS patients experienced less intraoperative bleeding (60 mL [interquartilerange(IQR), 50-100 mL] vs. 80 mL [IQR, 50-100 mL]; P = 0.027) and a shorter postoperative hospital stay (4 days [IQR, 3-5 days] vs. 5 days [IQR, 4-6 days]; P = 0.041) than the VATS patients. The two surgical approaches were comparable concerning other perioperative outcomes and postoperative complications (20.00% vs. 26.11%; P = 0.396). Additionally, during a median follow-up period of 66 months, RATS and VATS achieved comparable 5-year overall survival (90.48% vs. 87.93%; P = 0.891), recurrence-free survival (83.37% vs. 83.18%; P = 0.782), and cumulative incidence of death. Further subgroup comparison also demonstrated comparable long-term outcomes between the two approaches. Finally, multivariate Cox analysis indicated that the surgical approach was not independently correlated with long-term outcomes. The RATS approach shortened the postoperative hospital stay, reduced intraoperative bleeding by a statistically notable but clinically insignificant amount, and achieved long-term outcomes comparable with VATS in performing sub-lobectomy for octogenarians with early-stage small NSCLC.

Risk Factors for Chronic Atrial Fibrillation Following Lung Lobectomy

IntroductionPostoperative atrial fibrillation (POAF) is a common complication following lung lobectomy and is associated with increased risk of stroke, mortality, and prolonged hospital length of stay. The purpose of this study was to define the risk factors for POAF after lobectomy, hypothesizing that operative approach would be associated with risk of chronic POAF. MethodsThe TriNetX database was used to identify adult patients with no history of arrythmia receiving elective lung lobectomy for cancer from 7/6/2003-7/6/2023. Patients were categorized by approach: video-assisted thoracoscopic surgery (VATS) or open. The outcome of interest was the presence of POAF occurring at 1-3 months (“early”) and 12-24 months postop (“chronic”). Propensity matching was performed to reduce bias between cohorts. ResultsWe identified 22,998 patients: 8472 (36.8%) who received open and 14,526 (63.2%) VATS lobectomy. The rate of early POAF was 3.7% of VATS and 5.3% of open patients. The rate of chronic POAF was 5.5 % of VATS patients and 6.2% of open lobectomy patients. Propensity matching decreased bias between the approach groups, creating 7942 pairs for analysis. After matching, the risk of early POAF was greater in the open approach (5.5% open vs 3.4% VATS, risk ratio 1.607 (95% confidence interval 1.385-1.865), P < 0.001). Chronic POAF was (also) higher in the open approach (6.3% open vs 5.2% VATS, Risk Ratio 1.211 (95%CI 1.067-1.374), P = 0.003). ConclusionsPostoperative atrial fibrillation (POAF) occurs more commonly after open lobectomy, both acutely and chronically. Providers should counsel patients about the risk of chronic arrythmia after lung resection.

Surgical approach to pediatric mediastinal masses based on imaging characteristics.

Pediatric mediastinal masses may be resected using an open or video-assisted thoracoscopic surgery (VATS) approach. We sought to define the preoperative imaging findings predicting amenability to VATS. This multicenter retrospective study of pediatric patients undergoing either VATS or open surgical mediastinal mass resection between 2008 and 2018 evaluated the preoperative imaging descriptors associated with VATS. Postoperative endpoints included length of stay (LOS), 30-day readmission, 90-day mortality and complication rates. Mediastinal mass resection was performed in 33 patients. Median tumor size was 6cm, and 51.5% had anterior mediastinal tumors. The 23 (69.7%) patients who underwent VATS were significantly older (144months vs 32, P = 0.01) and larger (33.6kg vs 13.8 P = 0.03). Preoperative imaging characteristics in VATS included "well circumscribed", "smooth margins" and "cystic", while the open surgery group were "heterogeneous" and "coarse calcification". The open group had more germ cell tumors (60.0% vs 13.0%, P = 0.16) but no difference in malignancy. VATS patients had shorter LOS (2days vs 6.5, P = 0.24). Readmission, complication and mortality rates were similar. Pediatric patients with apparent malignancy frequently underwent open resection compared with the thoracoscopic group, although final malignant pathology was similar. Equivalent outcomes and shorter LOS should favor a minimally invasive approach. Level III.

Comparison of efficacy and safety of hybrid video-assisted thoracoscopic surgery vs. thoracotomy sleeve lobectomy for non-small cell lung cancer: a propensity score matching study.

BackgroundIt is unclear whether hybrid video-assisted thoracoscopic surgery (VATS) sleeve lobectomy (SL) could be an alternative to thoracotomy SL for non-small cell lung cancer (NSCLC) treatment. The aim of the study is to investigate the safety and efficacy of hybrid VATS SL.MethodsWe collected 112 patients who received hybrid VATS SL or thoracotomy SL for primary treatment of NSCLC at Liaoning Cancer Hospital & Institute from November 2016 to September 2021. Perioperative and survival data were collected, and retrospective analysis was conducted on 91 thoracotomy and 21 hybrid VATS SL patients to evaluate the safety and efficacy of two approaches. Propensity score matching (PSM) was used to minimize selection bias. The Kaplan-Meier method was applied to compare overall survival (OS) and recurrence-free survival (RFS). Follow-up data were obtained by outpatient clinical visit and nurse-led telephone.ResultsA total of 112 patients were included in this study, including thoracotomy patients (n=91) and hybrid VATS patients (n=21). In the non-match analysis, the baseline data of patients was similar between the two groups, except regarding the receipt of neoadjuvant therapy (P=0.087). After PSM (2:1), a total of 39 thoracotomy patients and 19 hybrid VATS patients were enrolled. The baseline variables were quite similar in both groups. In the hybrid group, the number of lymph nodes (25.9±8.5 vs. 32.9±9.7, P<0.01) and positive lymph nodes (3.7±2.9 vs. 5.6±4.0, P=0.045) were significantly higher than those in the thoracotomy group. The hybrid group was associated with significantly shorter postoperative hospital stay (9.5±3.5 vs. 7.3±2.9, P=0.021) and chest tube duration time (6.6±3.1 vs. 5.3±1.5, P=0.031). No statistical difference in complications, reoperation, and recurrence were observed between the hybrid VATS SL and thoracotomy SL (P=1.0, P=1.0, P=0.472). The 30- and 90-day mortalities showed no differences between approaches (2.6% vs. 0%, P=1.0; 5.1% vs. 5.3%, P=1.0). No significant differences were found between thoracotomy and hybrid VATS SL in 3-year OS (P=0.614) and 3-year RFS (P=0.750).ConclusionsHybrid VATS SL lobectomy may be a safe and feasible approach associated with similar oncologic prognosis and better postoperative recovery compared with thoracotomy SL for NSCLC treatment.

Thoracoscopic giant lung bullaectomy: our initial experience

BackgroundGiant lung bullae (GLB) are rare, and the only currently available management involves either an open surgical resection (thoracotomy) or the newer minimally invasive resection consisting of video-assisted thoracoscopic surgery (VATS). The aim of our study was to evaluate the possible influence of GLBs pulmonary attachment on patient's post-operative complications.MethodsA retrospective analysis included all consecutive patients with GLBs who underwent bullae's surgical resection from 7/2007 to 12/2018. GLBs patient's individual characteristics, including demographics, comorbidities, and clinical pre-operative, surgical intra-operative and post-operative data were evaluated.Results20 patients with GLBs, 15 males and 5 females with average age of 48.9 years (range, 22–67 years) underwent 21 surgical procedures. The GLBs were located in the right lung in 12 patients, in the left lung in seven patients, and in both lungs in one patient. Fifteen patients (75%) were symptomatic on admission and underwent urgent surgery. Five asymptomatic patients (25%) were operated on electively. Thirteen from 21 surgical procedures (61.9%) were VATS bullectomy, while the other eight were thoracotomies (38.1%). Complications included pneumonia successfully treated with intravenous antibacterial therapy in two thoracotomy patients and in one VATS patient (three patients, 14.2%) and a prolonged air leak in two thoracotomy and four VATS patients (six patients, 28.5%). Out of 21 GLBs, eight had a wide attachment with lung parenchyma (wide-based bullae's) and 13 had a short attachment (short-based bullae's). Two re-operated patients, with prolonged air leak complicated with empyema, had a wide-based GLBs. The median hospital stay was nine days. All patients completed the 24-month follow-up.ConclusionsMinimally invasive video-assisted thoracoscopic surgery as an open thoracotomy surgery is a safe and effective for giant lung bullae (GLB). Patients with wide-based GLBs were more likely to develop postoperative prolonged air leak that requiring re-operation.

Early video-assisted thoracoscopic surgery (VATS) for non-emergent thoracic trauma remains underutilized in trauma accredited centers despite evidence of improved patient outcomes

Thoracic injury is a major contributor to morbidity in trauma patients. There is limited data regarding practice patterns of video-assisted thoracoscopic surgery (VATS) across trauma-accredited hospitals in the United States. We hypothesized that early VATS remains underutilized affecting patient outcomes. We evaluated a cohort of patients who underwent non-urgent thoracic surgical intervention for trauma from the ACS-TQIP database in 2017 excluding patients who were discharged within 48-h or died within 72-h. We selected patients who underwent partial lung resection and decortication to assess the effect of early (day 2-5) versus late VATS. Univariate followed by multivariate regression analyses were utilized to evaluate the independent impact of timing. Over 12months, 997,970 patients were admitted to 850 trauma-accredited centers. Thoracic injury occurred in 23.5% of patients, 1% of whom had non-urgent thoracic procedures. A total of 406 patients underwent VATS for pulmonary decortication with/out partial resection, 39% were Early VATS (N = 159) compared to 61% late VATS (N = 247). Both groups had comparable demographics and comorbidities with exception of a higher ISS score in the late surgical group (17.9 ± 9.8 vs 14.9 ± 7.6, p < 0.01). The late VATS patients' group had higher rates of superficial site infection, unplanned intubation, and pneumonia. Early VATS was associated with shorter ICU stay and HLOS. Multivariate analysis confirmed the independent effect of surgical timing on postoperative complications and LOS. The conversion rate from VATS to thoracotomy was 1.9% in early group compared to 6.5%, p = 0.03. There was no difference in surgical pattern among participating facilities. Despite established practice guidelines supporting early VATS for thoracic trauma management, there is underutilization with less than half of patients undergoing early VATS. Early VATS is associated with improved patient outcomes.

Clinical evaluation of the rapid recovery of patients who underwent video-assisted thoracoscopic lung surgery under non-intubated anesthesia.

BackgroundNon-intubated anesthesia thoracoscopic surgery is an evolving form of minimally invasive thoracic surgery. It has had encouraging results in the treatment of lung cancer, and the current concept of enhanced recovery after surgery has become indispensable to surgical treatment. Our center retrospectively evaluated the clinical effect of rapid postoperative rehabilitation in patients who underwent thoracoscopic lung surgery under non-intubated anesthesia.MethodsThe clinical data of 192 patients undergoing video-assisted thoracoscopic surgery (VATS) at the Department of Thoracic Surgery of The First People’s Hospital of Yunnan Province were retrospectively analyzed. Among them, 75 received double-lumen endotracheal intubation anesthesia, and 117 received a laryngeal mask instead of endotracheal intubated anesthesia. Comparing the intra-and post-operative indicators difference of these 2 groups.ResultsThere were no significant differences in the postoperative complications, length of hospital stay, hemoglobin counts and platelet count 24 h after surgery between the non-intubated anesthesia and intubated anesthesia groups (P>0.05). In terms of the postoperative rehabilitation indicators of the VATS patients, the non-intubated anesthesia group had an earlier recovery in terms of water (food) intake, out-of-bed activity, and defecation (exhaust) times (P<0.001), less postoperative complications and adverse throat reactions (P<0.05), and higher levels of satisfaction (P<0.05) than the intubated anesthesia group. Compared to the intubated anesthesia group, the non-intubated anesthesia group had fewer changes of white blood cell counts, neutrophil percentages and lymphocytes percentages 24 h postoperatively (9.25×109 vs. 7.67×109, P=0.045; 7.06 vs. 5.53, P=0.039; 1.45 vs. 1.27, P=0.017), significant reduction pleural drainage after restoring oral intake in postoperative 24 and 48 h (198.43 vs. 131.07 and 114.04 vs. 57.47 mL, P<0.001), shorter postoperative thoracic tube drainage times (3.73 vs. 3.13 d, P<0.001). Notably, there was no difference between the smoking history and previous medical history of the patients in the 2 groups.ConclusionsCompared to intubation by general anesthesia, non-intubated thoracoscopic anesthesia is a safe and effective option. Patients who undergo non-intubated thoracoscopic lung surgery have a rapid recovery after surgery. Thus, it is worthy of promotion in clinical surgery settings.

Robotic vs Thoracoscopic Anatomic Lung Resection in Obese Patients: A Propensity-Adjusted Analysis

BackgroundMinimally invasive lung resections can be particularly challenging in obese patients. We hypothesized robotic surgery (RTS) is associated with less conversion to thoracotomy than video-assisted thoracoscopic surgery (VATS) in obese populations. MethodsThe Society of Thoracic Surgeons General Thoracic Surgery Database, Epithor French National Database, and McMaster University Thoracic Surgical Database were queried for obese (body mass index ≥30 kg/m2) patients who underwent VATS or RTS lobectomy or segmentectomy for clinical T1-2, N0-1 non-small cell lung cancer between 2015 and 2019. Propensity score adjusted logistic regression analysis was used to compare the rate of conversion to thoracotomy between the VATS and RTS cohorts. ResultsOverall, 8108 patients (The Society of Thoracic Surgeons General Thoracic Surgery Database: n = 7473; Epithor: n = 572; McMaster: n = 63) met inclusion criteria with a mean (SD) age of 66.6 (9) years and body mass index of 34.7 (4.5) kg/m2. After propensity score adjusted multivariable analysis, patients who underwent VATS were >5-times more likely to experience conversion to thoracotomy than those who underwent RTS (odds ratio, 5.33; 95% CI, 4.14-6.81; P < .001). There was a linear association between the degree of obesity and odds ratio of VATS conversion to thoracotomy compared with RTS. VATS patients had a longer mean length of stay (5.0 vs 4.3 days, P < .001), higher rate of respiratory failure (2.8% [168 of 5975] vs 1.8% [39 of 2133], P = .026), and were less likely to be discharged to their home (92.5% [5525 of 5975] vs 94.3% [2012 of 2133]; P = .013) compared with RTS patients. ConclusionsIn obese patients, RTS anatomic lung resection is associated with a lower rate of conversion to thoracotomy than VATS.

Pivotal role of video-assisted thoracoscopic surgery in improving survival outcome of stage I non-small cell lung cancer in day surgery patients.

BackgroundLung cancer, the leading cause of cancer‐related deaths worldwide, has high morbidity rates. Video‐assisted thoracoscopic surgery (VATS) as day surgery makes surgical treatment ideally in time with the same quality of medical care. This study aimed to assess the safety of stage I NSCLC patients who underwent VATS at a day surgery center.MethodsWe retrospectively analyzed the clinical characteristics and tumor features of VATS patients at a single center, West China Hospital, from June 1, 2019, to December 31, 2020. Patients fulfilled all inclusion criteria, did not meet any exclusion criteria and underwent wedge resection, segmentectomy, or lobectomy with systematic lymph node dissection.ResultsThe median patient age was 43 (range, 19–67) years. Of the 209 patients, most were women. A total of 108 (51.7%) patients underwent segmentectomy, 87 (41.6%) lobectomy, and 14 (6.7%) wedge resection with systematic lymph node dissection. According to the AJCC/UICC eighth edition of lung cancer stage grouping, stages IA, IA1, IA2, and IA3 were 195 (93.3%), 122 (58.4%), 50 (23.9%), and one (0.5%), respectively. A total of 36 (17.2%) patients were stage 0. Adenocarcinoma was predominantly the postoperative pathological diagnosis, as only 14 (6.7%) were benign. A total of 201 (96.17%) patients were discharged without a chest tube. The most common chief complaints were cough, incisional pain, and shortness of breath. No severe complications or life‐threatening emergencies were observed.ConclusionsThe day surgery mode of VATS for stage I NSCLC is safe and feasible, which makes surgical treatment ideally in time for stage I NSCLC patients with the same quality of medical care.

Video-Assisted Thoracoscopic Surgery Lung Resection in United States Veterans: Trends and Outcomes versus Thoracotomy.

Video-assisted thoracoscopic surgery (VATS) offers reduced morbidity compared with open thoracotomy (OT) for pulmonary surgery. The use of VATS over time has increased, but at a modest rate in civilian populations. This study examines temporal trends in VATS use and compares outcomes between VATS and OT in the Veterans Health Administration (VHA). Patients who underwent pulmonary surgery (wedge or segmental resection, lobectomy, or pneumonectomy) at Veterans Affairs centers from 2008 to 2018 were retrospectively identified using the Veterans Affairs Surgical Quality Improvement Project database. The cohort was divided into OT and VATS and propensity score matched, taking into account the type of pulmonary resection, preoperative diagnosis, and comorbidities. Thirty-day postoperative outcomes were compared. The prevalence of VATS use and respective complications over time was also analyzed. A total of 16,895 patients were identified, with 5,748 per group after propensity matching. VATS had significantly lower rates of morbidity and a 2-day reduction in hospital stay. Whereas 76% of lung resections were performed open in 2008, nearly 70% of procedures were performed using VATS in 2018. While VATS was associated with an 8% lower rate of major complications compared with thoracotomy in 2008, patients undergoing VATS lung resection in 2018 had a 58% lower rate of complications (p < 0.001). VATS utilization at VHA centers has become the predominant technique used for pulmonary surgeries over time. OT patients had more complications and longer hospital stays compared with VATS. Over the study period, VATS patients had increasingly lower complication rates compared with open surgery.

Patient-Reported Outcomes of Video-Assisted Thoracoscopic Surgery Versus Thoracotomy for Locally Advanced Lung Cancer: A Longitudinal Cohort Study.

The effects of video-assisted thoracoscopic surgery (VATS) and traditional thoracotomy with respect to patient-reported outcomes (PROs) have only been assessed for early-stage lung cancer. This study was a longitudinal PRO assessment to compare the effects of these surgeries for locally advanced (stage II and III) lung cancer from the patients' perspective. We investigated lung cancer patients from a previous prospective, multicentre study. Longitudinal data of clinical characteristics and PROs were collected. PROs were obtained preoperatively, daily in the hospital postoperatively, and weekly up to 4 weeks after discharge or the beginning of postoperative adjuvant therapy. Symptoms and impact on daily functioning and quality of life (QOL) were assessed by using the MD Anderson Symptom Inventory for lung cancer and a single-item QOL scale. Trajectories of PROs over the investigation period were compared. Overall, 117 primary lung cancer patients (stage II or III), including 63 and 54 patients who underwent VATS and traditional thoracotomy, respectively, were included. During postoperative hospitalization, VATS patients reported milder disturbed sleep (p = 0.048), drowsiness (p = 0.008), and interference with activity (p = 0.001), as well as better work ability (p < 0.0001), walking ability (p < 0.0001), and life enjoyment (p = 0.004). Post-discharge, VATS patients had less distress (p = 0.039), milder pain (p = 0.006), better work ability (p = 0.001), and better QOL (p = 0.047). Locally advanced lung cancer patients who underwent VATS had lower postoperative symptom burden, less daily function interference, and better QOL than those who underwent thoracotomy.

Comparison of thoracoscopy vs. thoracotomy on musculoskeletal outcomes of children with congenital pulmonary airway malformation (CPAM)

Background: It has been postulated that video-assisted thoracoscopic surgery (VATS) is superior than conventional thoracotomy for resection of congenital pulmonary airway malformation (CPAM) in terms of shorter hospital length of stay, reduced post-operative complication and better long-term pulmonary outcome. However, there is limited available data concerning the effect of VATS and conventional thoracotomy on musculoskeletal aspects in patients with CPAM. This study aims to compare the long-term effects of both surgical techniques on musculoskeletal outcomes in this group of patients.Methods: Thirty-five patients with mean age of 11.38 years old who underwent VATS or conventional thoracotomy for CPAM resection were recruited in this study. The mean follow-up time was 10.42 years (5.48 to 17.71 years). Musculoskeletal examination included screening of musculoskeletal deformities (elevation of shoulder, asymmetry of nipple level, breast/ pectoral muscle maldevelopment, winging of scapula, scoliosis), measurement of bilateral chest wall in relation to anatomical parameter, and testing of shoulder range of motion and power.Results: The prevalence of winged scapula was significantly lower in patients who underwent VATS than thoracotomy (13% vs 58%, p = 0.008). There is also a smaller reduction in operated-side chest wall vertical distance in VATS patients (0.982 vs 0.956, p = 0.058). There were no significant difference in prevalence of other musculoskeletal deformities, other chest wall measurements, shoulder range of motion and power between two groups.Conclusion: Thoracoscopy decreases the incidence of scapular winging but has no effect on effect on other musculoskeletal deformities.

Thoracoscopy versus thoracotomy for congenital lung malformations treatment: A single center experience.

Our aim is to compare thoracoscopy to thoracotomy in the treatment of congenital lung malformations (CLM) in children. We report a retrospective monocentric cohort study. Patients treated at our Center for CLM (1991-2020) were divided in two groups: patients treated with video-assisted thoracoscopic surgery (VATS) and open thoracotomy (OT). Characteristics of the two groups were compared through statistical analysis (GraphPad Prism7). A p value less than .05 was considered statistically significant. One hundred six patients were included: 58 in VATS group, 48 in OT group. Prenatal diagnosis was possible in 73.6%. The most frequent surgical procedures were lobectomy (43.4%) and sequestrectomy (22.6%). All VATS patients underwent lung exclusion, mostly by endobronchial blocker (69%). Mean operative time was 146.1 min (±52.04 SD) in VATS and 159.2 (±46.53 SD) in OT (p = .1973). Conversion to OT was necessary in 20.6% of VATS patients, but decreased in the last 5 years (6.2%). There were not any intraoperative complication. Respectively in VATS and OT group, length of stay (LOS) was 4.5 days ± 3.6 SD versus 7.7 ± 3.4 SD (p < .0001), chest tube duration 2.8 days ± 3.4 SD versus 3.7 ± 2.4 SD (p < .0001), antibiotic treatment duration 3.7 days ± 4.7 SD versus 5 ± 2.6 SD (p = .1196). Postoperative complications were described in 22.6%. The commonest histological diagnosis (40.6%) was congenital pulmonary airway malformation. VATS resulted a feasible, effective and safe technique. Operative time and postoperative complications were similar in VATS and OT groups. VATS conversion rate decreased in time. VATS had a statistically significant shorter LOS and chest tube duration.

Post-operative hypercoagulable whole blood profiles in patients undergoing open thoracotomy vs video-assisted thoracoscopic surgery.

Patients undergoing video-assisted thoracoscopic surgery (VATS) have a lower risk of thrombosis compared to those undergoing open thoracotomy (OT) which may be due to several post-operative factors such as early mobilisation, shorter hospital stays, lower transfusion rates and lower risk of infections. Whether the higher thrombotic risk after OT is also linked to a peri-operative hypercoagulable state is a matter of debate. We therefore conducted a case-control study to compare peri-operative coagulation profiles in patients with primary lung cancer undergoing VATS vs OT. All consecutive patients undergoing VATS or OT for primary lung cancer at the Department of Thoracic Surgery of Padua University Hospital, Italy, between February and June 2018 were enrolled. Each patient provided a venous blood sample at least 30 min prior to surgical incision (T0) and 4±1 days after surgery (T1). Peri-operative coagulation profiles were assessed via traditional, viscoelastic whole blood (ROTEM® [Instrumentation Laboratory-Werfen]) and impedance aggregometry (Multiplate® Analyser [Roche Diagnostics]) tests. We enrolled 65 patients (males 43, females 22; mean age 65±13 years) of whom 35 (54%) underwent VATS and 30 (46%) underwent OT. Compared to healthy controls, the surgical group (VATS and OT patients) had a significantly shorter clot formation time and higher alpha angle and maximum clot firmness values, as well as increased mean platelet function. In the post-operative period, patients who underwent OT had a significantly shorter clot formation time, higher alpha angle and maximum clot firmness values and higher mean platelet function vs VATS patients. Whole blood ROTEM® profiles and Multiplate® aggregometry identified a more hypercoagulable post-operative state in patients who underwent OT than in those who underwent VATS. Larger studies are warranted to confirm our results and ascertain whether the observed hypercoagulability might promote post-operative thrombosis.

Higher Long-term Quality of Life Metrics After Video-Assisted Thoracoscopic Surgery Lobectomy Compared With Robotic-Assisted Lobectomy

Robotic-assisted thoracic surgery (RATS) lung lobectomy has emerged as an alternative approach to video-assisted thoracoscopic surgery (VATS). Patient-reported outcomes comparing these approaches have been limited. At a single, high-volume academic center, patients undergoing VATS and RATS lobectomies for stage I and II non-small cell lung cancer from 2014 to 2018 were evaluated. The European Organisation for Research and Treatment of Cancer Quality of Life of Cancer Patients Questionnaire (QLQ-C30) and Quality of Life Questionnaire in Lung Cancer (QLQ-LC13), along with the Fear of Recurrence (FoR) survey, were administered preoperatively and at 1, 6, and 12 months postoperatively. Raw scores underwent linear transformation (0-100 scale). Linear mixed-effects models were used for quality of life and FoR score comparisons. The study included 219 patients (139 VATS and 80 RATS). RATS patients had longer (P < .05) operative times and a higher incidence (P < .05) of postoperative myocardial infarction compared to VATS patients. VATS patients reported higher (P < .05) QLQ-C30 summary scores postoperatively and at 12 months, including higher (P < .05) Social Functioning and Cognitive scores, and less (P < .05) appetite loss. VATS patients reported decreased (P < .05) QLQ-LC13 symptom summary scores at 6 months postoperatively, including decreased (P < .05) dyspnea, neuropathy, and pain compared with RATS patients. VATS patients also reported lower (P < .05) FoR summary scores at 6 months postoperatively. VATS patients report improvement in select quality of life and FoR measures after lobectomy. Further study comparing these 2 approaches is required.

Outcomes of video-assisted thoracoscopic surgery lobectomy in septuagenarians.

Spread of technology and increased surveillance have led to more patients with lung cancers being identified than ever before. Increasingly, patients from the elderly population are referred for surgery; however, many studies do not focus on this patient group. We reviewed the outcomes of septuagenarians who underwent lobectomy via an open thoracotomy (OT) or video-assisted thoracoscopic surgery (VATS) approach to determine whether the VATS approach would result in superior post-operative outcomes. Between January 2010 and June 2016, a total of 96 patients aged 70 years or older underwent a lobectomy for non-small cell lung carcinoma. Patients who underwent resection for metastatic disease, small cell lung cancer or neuroendocrine tumour were excluded. Demographic details, early and late post-operative outcomes including post-operative arrhythmia, myocardial infarction, respiratory failure, cerebrovascular events, infection, prolonged air leak, delirium, readmission and 30-day mortality were studied. Mean follow-up duration was 23 ± 19.1 months. Seventy-five patients underwent lobectomy via a VATS approach and 21 patients underwent lobectomy via an OT approach. There was no 30-day mortality and no difference in overall survival between the two techniques (P = 0.25). There was no significant difference between the two techniques with regard to post-operative stroke, myocardial infarction, atrial fibrillation, pneumonia, delirium or bronchopleural fistula. VATS patients had a significantly shorter mean hospital length of stay (VATS 4.7 days, OT 9.3 days, P = 0.005). Septuagenarians with non-small cell lung carcinoma can successfully undergo curative lung resection with a low incidence of post-operative complications.

Non-intubated anesthesia in patients undergoingvideo-assisted thoracoscopic surgery: Asystematic reviewand meta-analysis.

IntroductionNon-intubated anesthesia (NIA) has been proposed for video-assisted thoracoscopic surgery (VATS), although how the benefit-to-risk of NIA compares to that of intubated general anesthesia (IGA) for certain types of patients remains unclear. Therefore, the aim of the present meta-analysis was to understand whether NIA or IGA may be more beneficial for patients undergoing VATS.MethodsA systematic search of Cochrane Library, Pubmed and Embase databases from 1968 to April 2019 was performed using predefined criteria. Studies comparing the effects of NIA or IGA for adult VATS patients were considered. The primary outcome measure was hospital stay. Pooled data were meta-analyzed using a random-effects model to determine the standard mean difference (SMD) with 95% confidence intervals (CI).Results and discussionTwenty-eight studies with 2929 patients were included. The median age of participants was 56.8 years (range 21.9–76.4) and 1802 (61.5%) were male. Compared to IGA, NIA was associated with shorter hospital stay (SMD -0.57 days, 95%CI -0.78 to -0.36), lower estimated cost for hospitalization (SMD -2.83 US, 95% CI -4.33 to -1.34), shorter chest tube duration (SMD -0.32 days, 95% CI -0.47 to -0.17), and shorter postoperative fasting time (SMD, -2.76 days; 95% CI -2.98 to -2.54). NIA patients showed higher levels of total lymphocytes and natural killer cells and higher T helper/T suppressor cell ratio, but lower levels of interleukin (IL)-6, IL-8 and C-reactive protein (CRP). Moreover, NIA patients showed lower levels of fibrinogen, cortisol, procalcitonin and epinephrine.ConclusionsNIA enhances the recovery from VATS through attenuation of stress and inflammatory responses and stimulation of cellular immune function.

P2.16-04 Single-Port Video-Assisted Thoracoscopic Surgery Reduces Patient-Reported Symptom Burden in Patients Undergoing Lung Resection

Symptom relief has been considered one of the most important targets in recovery from a surgery. This study aimed to evaluate the advantages of single-port video-assisted thoracoscopic surgery (VATS) in reducing postoperative symptom burden, by comparison with multi-port VATS in patients undergoing lung resection. Data were collected from an ongoing, real-world, multicenter, prospective, observational study initiated in November 2017 (NCT03341377). The MD Anderson Symptom Inventory for lung cancer (MDASI-LC) was administered to assess the severity of postoperative symptoms and their interference with daily functioning preoperatively and daily postoperatively until discharge. A symptom burden index (MDASI-SI) was generated by averaging the top 5 severe symptoms. MDASI-SI was compared between groups using the Wilcoxon rank sum test. The changes of symptoms over hospitalization were compared using mixed modeling. Among 175 patients who underwent lung resection, 89 underwent single-port VATS, 30 two-port VATS, 13 three-port VATS, and 43 four-port VATS. We combined two- and three-port VATS patients due to the small sample size. The top 5 severe symptoms were pain, fatigue, coughing, disturbed sleep, and shortness of breath for all the patients. There were no significant differences between single-, two/three-, and four-port VATS in preoperative MDASI-SI. The median postoperative hospital stay was 6 days for each group. The MDASI-SI scores of single-port VATS (median=3.6; inter quartile range (IQR)=2.4) were significantly lower than those of two/three-port (median=4.6; IQR=2.8; P=0.043) and four-port VATS (median=5.1; IQR=3.3; P=0.0005) on postoperative day (POD) 1. Compared to four-port VATS, patients who underwent single-port VATS experienced significantly lower symptom burden from POD 1 to POD 6 (estimate=-0.77; SE=0.28; P=0.005). This study provided real-world evidence that the single-port VATS has a significant benefit of reducing symptom burden in patients undergoing lung resection during the early postoperative period. The long-term benefit and its impact on patient’s quality of life, adjuvant therapy, and survival need to be investigated in further studies.
