Multidisciplinary Management of Descending Necrotizing Mediastinitis: Is Thoracoscopic Treatment Feasible?

Background: Descending necrotizing mediastinitis (DNM) is a life-threatening condition, generally caused by downward dissemination of oropharyngeal infections through cervical fascial planes. Mediastinal drainage is conventionally achieved by thoracotomy, but a Video-Assisted Thoracoscopic Surgery (VATS) approach is gaining interest due to the reduced invasiveness of procedure. We aimed to evaluate the effectiveness of VATS treatment in patients with DNM. Methods: We conducted a retrospective multicenter study including patients with descending mediastinitis that underwent mediastinal drainage through VATS (VATS group) or thoracotomy (thoracotomy group), both in association with cervical drainage. Patients with mediastinitis secondary to cardiac, pulmonary, or esophageal surgery were excluded. The intergroup differences regarding surgical outcome and postoperative morbidity and mortality were compared. Results: A total of 21 patients were treated for descending mediastinitis during the study period. Cervicotomy and thoracotomy were performed in 15 patients (71%), while cervicotomy and VATS were performed in 6 patients (29%). There were no significant differences in surgical outcome, postoperative morbidity, and mortality between groups. VATS treatment was not associated with a higher complication rate. Patients in the VATS group had a shorter operative time (p = 0.016) and shorter ICU stay (p = 0.026). Conclusions: VATS treatment of DNM is safe and effective. The comparison with thoracotomy showed no significant differences in postoperative morbidity and mortality. The VATS approach is associated with a shorter operative time and ICU stay than thoracotomy.

Comparative Analysis of Short-Term Outcomes of Anatomical Lung Resections Using Video-Assisted Thoracoscopic Surgery and Thoracotomy Approaches

Objective: To analyze short-term outcomes of anatomical lung resections using video-assisted thoracoscopic surgery (VATS) and thoracotomy approaches.Materials and methods: Our retrospective study included 530 patients who underwent surgery for various lung diseases in the thoracic surgery unit of City Multidisciplinary Hospital No. 2 (Saint Petersburg, Russian Federation) between 2014 and 2021. The patients were grouped based on the surgical approach: group 1 for patients who underwent VATS (n = 378), group 2 for patients who underwent thoracotomy (n = 120), and group 3 for patients who underwent conversion from VATS to thoracotomy (n = 32).Results: Tumor size, paranodal and peribronchial changes were unfavorable prognostic factors for conversion from VATS to thoracotomy (odds ratio [OR] = 1.032, CI: 1.013-1.051, P < .001; OR = 4.416, CI: 2.100-9.283, P < .0005; OR = 3.109, CI: 1.496-6.462, P < .002). Patients from group 1 and group 3 mostly had minor complications, whereas 32 patients (53%) from group 2 developed grade III-V complications according to Thoracic Morbidity and Mortality classification system. High Charlson Comorbidity Index (CCI), thoracotomy approach, emphysematous changes, adhesions, and absence of interlobar fissures were independent unfavorable prognostic factors for complications in the early postoperative period (OR = 1.665, CI: 1.031-2.691, P < .05; OR = 1.874, CI: 1.1433.070, P < .05; OR = 1.8803, CI: 1.126-2.888, P < .05; OR = 1.548, CI: 1.010-2.370, P < .05; OR = 1.612, CI: 1.053-2.466, P < .05).Conclusions: VATS is an effective and safe approach for anatomical lung resection. Tumor size above 40 mm, significant paranodal and peribronchial changes were risk factors for conversion from VATS to thoracotomy. CCI above 5, thoracotomy approach, emphysematous changes, adhesions, and absence of interlobar fissures were independent unfavorable prognostic factors for complications in the early postoperative period.

Wedge Resection Outcomes: A Comparison of Video-Assisted and Robot-Assisted Wedge Resections

BackgroundQuality of oncologic resection for early-stage non-small cell lung cancer (NSCLC) may differ by surgical approach. Minimally invasive surgery has become the standard for surgical treatment of NSCLC. Our study compares quality of wedge resection by video-assisted thoracoscopic surgery (VATS) vs robotic video-assisted thoracoscopic surgery (RVATS). We hypothesized that RVATS would result in higher quality resections and improved patient outcomes. MethodsA retrospective cohort analysis was completed using the National Cancer Database for patients with clinical stage 1 NSCLC with tumor size ≤2 cm who underwent a minimally invasive surgery wedge resection from 2010 to 2019. Wedge resections approached with RVATS were compared with VATS. A 1:1 propensity score matched analysis was performed. ResultsThe cohort included 16,559 patients; 80.4% (13,406) received VATS and 18.9% (3153) received RVATS. Compared with RVATS, a VATS approach was associated with a lower likelihood of lymph nodes being examined (59.0% vs 75.2%; P < .001), fewer nodes dissected (median, 4 vs 5; P < .001), and less adjuvant systemic therapy administered (1.3% vs 2.2%; P < .001). Propensity score matching resulted in 2590 balanced pairs. Statistical significance was maintained for likelihood of lymph nodes examined, number of nodes dissected, and adjuvant systemic therapy administered. There was no significant difference in nodal upstaging after propensity score matching (3.7% vs 4.3%; P = .37). ConclusionsCompared with the VATS approach, wedge resections by RVATS for early-stage NSCLC were more likely to be associated with increased lymph nodes resected. These data may support increased use of RVATS for wedge resections.

Robot-Assisted Thoracoscopic Resection of Ectopic Parathyroid Tissue in Mediastinum: A Scoping Review.

Ectopic parathyroid tissue in the mediastinum represents a rare and potentially serious clinical entity with challenging diagnostic and surgical management. The main surgical approach for this issue is open thoracotomy, which is a safe technique but carries risks and complications associated with such as extensive surgery. The purpose of this study is to demonstrate robotic thoracic surgery as an alternative and potentially advantageous method to treat patients with ectopic parathyroid adenomas compared with open and video-assisted thoracoscopic surgery approaches. A total of 13 reports in the literature were identified that provided details in terms of complications, surgical approach, and results of minimally invasive surgical resection of mediastinal ectopic parathyroid tissue.

Objective improvement in dexterity for trainees undergoing a video-assisted thoracoscopic surgery simulation program, a prospective single center study.

Video-assisted thoracoscopic surgery (VATS) is the recommended approach for the management of early-stage operable non-small cell lung carcinoma as well as for other pathologies of the thoracic cavity. Although VATS approaches have been largely adopted in Europe and North America, teaching the technique to novice thoracic surgery trainees remains challenging and non-standardized. Our objective was to assess the impact of a VATS simulation training program on the dexterity of thoracic surgery residents in a prospective single institution study. We developed a 6-month VATS simulation training program on two different dry-lab simulators (Johnson & Johnson Ethicon Stupnik® lobectomy model; CK Surgical Simulation® Crabtree perfused lobectomy model) and assessed the skills of first year thoracic surgery residents (study group, n=7) before and after this program using three standardized exercises on the Surgical Science Simball® Box (peg placement on a board, rope insertion in loops, precision circle cutting). The results were compared to those of last-year medical students who performed the same Simball® Box exercises at a 6-month interval without undergoing a training program (control group, n=5). For each participant, the travel distances of instruments, operation time and absences of periods of extreme motion were assessed for each exercise by the use of the computer-based evaluation of the Simball® Box. After the 6-month VATS training program, all residents revealed a significant increase of their performance status with respect to instrument travel distances operation times and absence of periods of extreme motion in all three exercises performed. The performance of the control group was not different from the study group prior to the training program and remained unchanged 6 months later, for all exercises and parameters assessed. Our results suggest that the implementation of a VATS simulation training program objectively increases the dexterity of thoracic surgery residents and could be an interesting training tool for their surgical education.

Interpretable machine learning accurately reclassifies lobectomy surgical approaches by cost

BackgroundThe volume of robotic lung resection continues to increase despite its higher costs and unproven superiority to video-assisted thoracoscopic surgery. We evaluated whether machine learning can accurately identify factors influencing cost and reclassify high-cost operative approaches into lower-cost alternatives. MethodsThe Florida Agency for Healthcare Administration and Centers for Medicare and Medicaid Services Hospital and Physician Compare datasets were queried for patients undergoing open, video-assisted thoracoscopic surgery and robotic lobectomy. K-means cluster analysis was used to identify robotic clusters based on total cost. Predictive models were built using artificial neural networks, Support Vector Machines, Classification and Regression Trees, and Gradient Boosted Machines algorithms. Models were applied to the high-volume robotic group to determine patients whose cost cluster changed if undergoing a video-assisted thoracoscopic surgery approach. A local interpretable model-agnostic explanation approach personalized cost per patient. ResultsOf the 6,618 cases included in the analysis, we identified 4 cost clusters. Application of artificial neural networks to the robotic subgroup identified 1,642 (65%) cases with no re-assignment of cost cluster, 583 (23%) with reduced costs, and 300 (12%) with increased costs if they had undergone video-assisted thoracoscopic surgery approach. The 5 overall highest cost predictors were patient admission from the clinic, diagnosis of metastatic cancer, presence of cancer, urgent hospital admission, and dementia. ConclusionK-means cluster analysis and machine learning identify a patient population that may undergo video-assisted thoracoscopic surgery or robotic lobectomy without a significant difference in total cost. Local interpretable model-agnostic explanation identifies individual patient factors contributing to cost. Application of this modeling may reliably stratify high-cost patients into lower-cost approaches and provide a rationale for reducing expenditure.

Comparing Robotic-Assisted Thoracoscopic Surgery (RATS) vs Video-Assisted Thoracoscopic Surgery (VATS) Approaches for Non-Small Cell Lung Cancer (NSCLC): a Systematic Review and Meta-Analysis

Video-assisted thoracoscopic surgery (VATS) has demonstrated its efficacy and improved clinical outcomes as an option for early-stage non-small cell lung cancer. The development of robotic-assisted thoracoscopic surgery (RATS) has become the newest alternative to VATS. This study aims to compare VATS and RATS in terms of clinical outcomes. This Systematic Review research used the PRISMA method. RATS is proven to be an alternative with superior results compared to VATS on the Mortality in 30 days parameter (OR 0.59, 95% CI = 0.40, 0.86, I2 : 0%; p&lt;0.006) and transfusion rate (OR = 0.50; 95% CI: 0.27 - 0.92, I2: 6%; p = 0.34). There was no significant difference between the RATS vs VATS procedure in terms of duration of surgery (OR = 0.50; 95%CI: 0.27 - 0.92), and intraoperative complications (OR 1.98, 95%CI: 0.12 - 32.44) and postoperative complications (OR 1.05, 95%CI: 0.93 - 1.19). The parameters of length of stay and chest drain duration in most of the studies show that VATS requires longer treatment time and thoracic drainage time than RATS. RATS can be an alternative to minimally invasive surgery in early-stage lung cancer with a lower risk of death and transfusion requirements than VATS, but there is no difference in the duration of surgery, as well as intraoperative and postoperative complications.

Video-assisted thoracoscopic epicardial pacing: A contemporary overview.

Video-assisted thoracoscopic surgery (VATS) has revolutionized the approach and management of pulmonary and cardiac diseases, and its applications have significantly expanded in the last two decades. Beyond its established role in thoracic procedures, VATS has also emerged as a valuable technique for various electrophysiological procedures, including pacemaker implantations, ablation procedures, and left atrial appendage exclusion. This paper presents a thorough review of the existing literature on pacing procedures performed using a VATS approach. By analyzing and synthesizing the available studies, we aim to provide an in-depth understanding of the current knowledge and advancements in VATS-based pacing procedures. A key focus of this review is the detailed description of implantation techniques via a VATS approach.

Management of Deep Neck Infection with Descending Mediastinitis using Video-Assisted Thoracoscopic Surgery

Descending mediastinitis is defined as the spread of oropharyngeal or odontogenic infection into the mediastinum. It occurs uncommonly and has a high mortality rate. Prompt commencement of broad-spectrum antibiotics combined with surgical drainage is crucial to limit further spread of infection. We report a case of extensive deep neck infection in a 66-year-old female which rapidly progressed to the contralateral neck complicated by descending anterior mediastinitis. She underwent a combined transcervical and video-assisted thoracoscopic surgery (VATS) for drainage of abscess and was put on 3 weeks of intravenous antibiotics coupled with another 3 weeks of oral antibiotics. Deep neck infection with descending mediastinitis can be successfully treated with antibiotics and early surgical drainage via a combined transcervical and VATS approach.

Off-Label Use of COR-KNOT Automated Fastener for Manual Bronchial Closure Through a Video-Assisted Thoracoscopic Surgery Approach.

Manual closure of the bronchial stump can be challenging during minimally invasive thoracic surgery. An automated fastener has been used for more than a decade in minimally invasive heart valve surgery to eliminate the need for manual knot tying during the suturing of prosthetic valves. Herein, we describe the use of the COR-KNOT automated fastener (LSI SOLUTIONS®, Victor, NY, USA) in a case of video-assisted left upper lobectomy with open section of the bronchus and manual closure with interrupted resorbable sutures for a malignant bronchial tumor located on the proximal part of the left upper lobe bronchus. This case represents, to our knowledge, the first case using the COR-KNOT device for minimally invasive pulmonary surgery.

Analyzing the impact of minimally invasive surgical approaches on post-operative outcomes of pneumonectomy and sleeve lobectomy patients.

Some patients with non-small cell lung cancer (NSCLC) have superior short- and long-term outcomes with sleeve lobectomy rather than pneumonectomy. Originally sleeve lobectomy was reserved for patients with limited pulmonary function, however, the reported superior results allowed sleeve lobectomy to be performed in expanded patient populations. In a further attempt to improve post-operative outcomes surgeons have adopted minimally invasive techniques Minimally invasive approaches have potential benefits to patients such as decreased morbidity and mortality while maintaining the same caliber of oncologic outcomes. We identified patients at our institution who underwent sleeve lobectomy or pneumonectomy to treat NSCLC from 2007 to 2017. We analyzed these groups in respect to 30- and 90-day mortality, complications, local recurrence, and median survival. We included multivariate analysis to determine the impact of a minimally invasive approach, sex, extent of resection, and histology. Differences in mortality were analyzed using the Kaplan-Meier method using the log-rank test to compare the groups. A two-tailed Z test for difference in proportions was done to analyze complications, local recurrence, 30-day and 90-day mortality. A total of 108 patients underwent sleeve lobectomy (n=34) or pneumonectomy (n=74) for treatment of NSCLC with 18 undergoing open pneumonectomy, 56 undergoing video-assisted thoracoscopic surgery (VATS) pneumonectomy, 29 undergoing open sleeve lobectomy, and 5 undergoing VATS sleeve lobectomy. There was no significant difference in 30-day mortality (P=0.064) but there was a difference in 90-day (P=0.007). There was no difference in complication rates (P=0.234) or local recurrence rates (P=0.779). The pneumonectomy patients had a median survival of 23.6 months (95% CI: 3.8-43.4 months). The sleeve lobectomy group had a median survival of 60.7 months (95% CI: 43.3-78.2 months) (P=0.008). On multivariate analysis extent of resection (P<0.001) and tumor stage (P=0.036) were associated with survival. There was no significant difference between the VATS approach and the open surgical approach (P=0.053). When considering patients undergoing surgery for NSCLC sleeve lobectomy resulted in lower 90-day mortality and better 3-year survival compared to patients undergoing PN. Having a sleeve lobectomy rather than a pneumonectomy and having earlier-stage disease lead to significantly improved survival on multivariate analysis. Having a VATS operation leads to a non-inferior post-operative outcome compared to open surgery.

Evaluation and Management of Primary Spontaneous Pneumothorax in Adolescents and Young Adults: A Systematic Review From the APSA Outcomes & Evidence-Based Practice Committee

Controversy exists in the optimal management of adolescent and young adult primary spontaneous pneumothorax. The American Pediatric Surgical Association (APSA) Outcomes and Evidence-Based Practice Committee performed a systematic review of the literature to develop evidence-based recommendations. Ovid MEDLINE, Elsevier Embase, EBSCOhost CINAHL, Elsevier Scopus, and Wiley Cochrane Central Register of Controlled Trials databases were queried for literature related to spontaneous pneumothorax between January 1, 1990, and December 31, 2020, addressing (1) initial management, (2) advanced imaging, (3) timing of surgery, (4) operative technique, (5) management of contralateral side, and (6) management of recurrence. The Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines were followed. Seventy-nine manuscripts were included. Initial management of adolescent and young adult primary spontaneous pneumothorax should be guided by symptoms and can include observation, aspiration, or tube thoracostomy. There is no evidence of benefit for cross-sectional imaging. Patients with ongoing air leak may benefit from early operative intervention within 24-48h. A video-assisted thoracoscopic surgery (VATS) approach with stapled blebectomy and pleural procedure should be considered. There is no evidence to support prophylactic management of the contralateral side. Recurrence after VATS can be treated with repeat VATS with intensification of pleural treatment. The management of adolescent and young adult primary spontaneous pneumothorax is varied. Best practices exist to optimize some aspects of care. Further prospective studies are needed to better determine optimal timing of operative intervention, the most effective operation, and management of recurrence after observation, tube thoracostomy, or operative intervention.

The transition to uniportal robotic surgery in the second decade of uniportal surgery.

Uniportal robotic surgery was created by Dr. Diego Gonzalez-Rivas as a fusion of his decade of experience with uniportal video-assisted thoracoscopic surgery (VATS) and his recent experience with the Intuitive Robotic System. It represents, in his view, the natural evolution of the uniportal technique in the era of robotic surgery. In this article, we discuss some of the novel issues that this raises, including capacitive coupling, and we describe the technique in detail to help surgeons who may be interested in starting uniportal robotic surgery. We go through case selection, which should start with wedge resections and lymphadenectomy. We look at port placement, which is more posterior and lower than the usual uniportal VATS approach, and we discuss the optimal instruments and ports for the technique. We discuss the role of the assistant in uniportal robotic surgery, which is a key part of the operation as we regard this as a two-surgeon technique. We then discuss the future and other possible robotic platforms that might be suitable for uniportal robotic surgery. It is an exciting new development for robotic surgery, and we recommend that this technique is suitable for advanced surgeons who are experienced in uniportal VATS lobectomy and in multiportal robotic surgery.

Surgical Approach and Persistent Opioid Use in Medicare Patients Undergoing Lung Cancer Resection

BackgroundRobotic and video-assisted thoracoscopic surgery (VATS) approaches for lung resection are associated with decreased inpatient opioid use compared with open surgery. Whether these approaches affect outpatient persistent opioid use remains unknown. MethodsNon-small cell lung cancer patients aged 66 years or more who underwent lung resection between 2008 and 2017 were identified from the Surveillance, Epidemiology, and End Results-Medicare database. Persistent opioid use was defined as filling an opioid prescription 3 to 6 months after lung resection. Adjusted analyses were performed to evaluate surgical approach and persistent opioid use. ResultsWe identified 19,673 patients: 7479 (38%) underwent open surgery, 10,388 (52.8%) VATS, and 1806 (9.2%) robotic surgery. Persistent opioid use was 38% in the entire cohort, including 27% of opioid naïve patients, and highest after open surgery (42.5%), followed by VATS (35.3%) and robotic (33.1%, P < .001). In multivariable analyses, robotic (odds ratio 0.84; 95% CI, 0.72-0.98; P = .028) and VATS (odds ratio 0.87; 95% CI, 0.79-0.95; P = .003) approaches were both associated with decreased persistent opioid use compared with open surgery in opioid naïve patients. At 12 months, patients resected using a robotic approach had the lowest oral morphine equivalent per month compared with VATS (133 vs 160, P < .001) and open surgery (133 vs 200, P < .001). Among chronic opioid patients, surgical approach was not associated with postoperative opioid use. ConclusionsPersistent opioid use after lung resection is common. Both robotic and VATS approaches were associated with decreased persistent opioid use compared with open surgery among opioid naïve patients. Whether a robotic approach yields additional long-term advantages over VATS warrants further investigation.

Primary Spontaneous Pneumothorax: Open Thoracotomy vs. Video-assisted Thoracoscopic Surgery: A Single-center Retrospective Cohort Study.

Primary spontaneous pneumothorax (PSP) is a spontaneous pneumothorax without underlying lung disease. The main goals of this study were to compare the outcomes of video-assisted thoracoscopic surgery (VATS) and open thoracotomy in patients with PSP. The current study is a retrospective cohort study of patients who were admitted to the emergency department or general surgery ward at Dr. Masih Daneshvari Hospital (Tehran, Iran) with the diagnosis of PSP and underwent surgery by open or VATS approach from 2006 to 2012. The groups were compared in terms of the length of operation, the length of hospitalization, recurrence, and postoperative complications. Data were analyzed using SPSS version 18.0, and Student's t test, analysis of variance (ANOVA), Chi square, and Fisher's exact test were employed. P values less than 0.05 were considered statistically significant. PSP was diagnosed in 90 patients who underwent surgery. Open thoracotomy and VATS procedures were performed in 65 (72.2%) and 25 (27.8%) patients, respectively. VATS was converted to open in seven cases (7.7%). Recurrent pneumothorax was the most common surgical indication for PSP. There was no significant difference between the two groups in terms of mean age, sex, smoking, side of the involved lung, previous pneumothorax history, mean length of hospitalization for recurrence, post-operation bleeding, and failure of lung expansion. However, the length of surgery (P=0.011) and air leakage (P=0.048) significantly differed between the two groups. When compared to open thoracotomy, VATS could be the primary treatment option in the surgical treatment of PSP due to the shorter length of surgery and decreased complications such as air leakage.

WITHDRAWN: Cost-effectiveness of video-assisted thoracoscopic surgery compared to open lobectomy in patients with early-stage lung cancer: Findings from the VIOLET randomised controlled trial

<h2>Abstract</h2><h3>Objectives</h3> Lung cancer is the leading cause of cancer death, and has the highest economic burden across Europe of all cancers. Early-stage disease is predominantly treated with surgery, and lung cancer resection using a video-assisted thoracoscopic surgery (VATS) approach has increased, despite limited randomised evidence of its effectiveness and cost-effectiveness compared to open lobectomy. The VIOLET randomised controlled trial compared VATS lobectomy with open surgery in participants with known or suspected (cT1-3, N0-1, M0) lung cancer recruited from nine UK centres. We report the trial cost-effectiveness analysis. <h3>Methods</h3> A within-trial cost-effectiveness analysis of VATS versus open lobectomy was conducted, with a one year time horizon, from a UK National Health Service and personal social services perspective. The primary outcome measure was quality-adjusted life years (QALYs), estimated using the EQ-5D-5L questionnaire. <h3>Results</h3> Mean QALYs to one year were 0.841 and 0.780 in the VATS and open groups respectively, (a statistically significant mean difference (MD) of +0.060, 95% CI +0.029, +0.092). Total costs of care were £10,879 and £13,581 in the VATS and open groups, (MD= -£2,702, 95% CI –£5,632, +£228). Differences in costs and QALYs favoured VATS, and when combined, resulted in VATS being clearly cost-effective. The probability that VATS is cost-effective at a willingness-to-pay threshold of £20,000 per QALY is >0.99, indeed VATS is considered cost-effective at any threshold, with negligible uncertainty around this finding. <h3>Conclusions</h3> VATS lobectomy provides good value for money. When considered alongside the published clinical findings from VIOLET that multiple outcomes were significantly improved with VATS, the policy implications are clear: VATS should be the first choice for suitable patients with early-stage lung cancer.

Surgical Outcomes of Video-Assisted versus Open Pneumonectomy for Lung Cancer: A Real-World Study.

The safety, feasibility and potential benefits of Video-assisted thoracoscopic surgery (VATS) pneumonectomy remain to be investigated. Patients receiving VATS or Open pneumonectomy during the study period were included to compare surgical outcomes. Propensity-score matched (PSM) analysis was performed to eliminate potential biases. From 2013 to 2020, 583 consecutive patients receiving either VATS (105, 18%) or Open (478, 82%) pneumonectomy were included. Conversion from VATS to open was found in 20 patients (19.0%). The conversion patients had similar rates of major complications and perioperative mortality compared with the Open group. After PSM, 203 patients were included. No significant differences were observed in major complications and perioperative mortality between the two groups. For patients with stage pT2 tumors, the major complication rate in the VATS group was significantly lower than in the Open group (7.6% vs. 20.6%, p = 0.042). Compared with left pneumonectomy, the incidence of bronchopleural fistula (BPF) was significantly higher in right pneumonectomy for both VATS (0 vs. 16.7%, p = 0.005) and Open (0.7% vs. 6.5%, p = 0.002) approaches. Perioperative results of VATS pneumonectomy are non-inferior to those of the Open approach. Conversion to open surgery does not compromise perioperative outcomes. Patients with lower pT stage tumors who need pneumonectomy may benefit from VATS.

Pulmonary Open, Robotic, and Thoracoscopic Lobectomy study: Outcomes and risk factors of conversion during minimally invasive lobectomy

ObjectiveConversion to thoracotomy continues to be a concern during minimally invasive lobectomy. The aim of this propensity-matched cohort study is to analyze the outcomes and risk factors of intraoperative conversion during video-assisted thoracoscopic surgery (VATS) and robotic lobectomy (RL). MethodsData from consecutive lobectomy cases performed for clinical stage IA to IIIA lung cancer was retrospectively collected from the Pulmonary Open, Robotic, and Thoracoscopic Lobectomy study consortium of 21 institutions from 2011 to 2019. The propensity-score method of inverse-probability of treatment weighting was used to balance the baseline characteristics across surgical approaches. Univariate logistic regression models were applied to test risk factors for conversion. Multivariable logistic regression analysis was conducted using a stepwise model selection method. ResultsSeven thousand two hundred sixteen patients undergoing lobectomy were identified: RL (n = 2968), VATS (n = 2831), and open lobectomy (n = 1417). RL had lower conversion rate compared with VATS (3.6% vs 12.9%; P < .0001). In the multivariable regression model, tumor size and neoadjuvant therapy were the most significant risk factors for conversion, followed by prior cardiac surgery, congestive heart failure, chronic obstructive pulmonary disease, VATS approach, male gender, body mass index, and forced expiratory volume in 1 minute. Conversions for anatomical reasons were more common in VATS than RL (66.6% vs 45.6%; P = .0002); however, conversions for vascular reasons were more common in RL than VATS (24.8% vs 14%; P = .01). The rate of emergency conversions was comparable between RL and VATS (0.5% vs 0.7%; P = .25) with no intraoperative mortalities. ConclusionsConverted minimally invasive lobectomies were not associated with worse perioperative mortality compared with open lobectomy. Compared with VATS lobectomy, RL is associated with a lower probability of conversion in this propensity-score matched cohort study.

Sleeve lobectomy in patients with non-small-cell lung cancer: a report from the European Society of Thoracic Surgery database 2021.

For centrally located lung tumours, sleeve lobectomy is preferred over pneumectomy. We report on the surgical practices and perioperative outcomes of sleeve resections based on data from the European Society of Thoracic Surgeons database. We retrieved data of patients undergoing sleeve lobectomy or bilobectomy from 2007 to 2021. We evaluated baseline characteristics, surgical approach, neoadjuvant treatments, morbidity and postoperative outcomes of open and video-assisted thoracoscopic surgery (VATS) procedures. In total, 1652 patients (median age: 63 years; females/males: 446/1206) underwent sleeve lobectomy (n = 1536) or bilobectomy (n = 116) by open thoracotomy (n = 1491; 90.2%) or VATS (n = 161; 9.8%) with a thoracotomy conversion rate of 21.1% (n = 34); 398 (24.1%) patients received neoadjuvant treatment. Overall morbidity and 30-day mortality were 40.6% and 2.2%, respectively. Bronchial anastomotic complications occurred in 29 patients (1.8%) with conservative treatment in 6 cases (20.7%) and operative management in 23 (79.3%). On multivariable analysis, factors related to the elevated risk of cardiopulmonary complications were body mass index &lt; 20 [odds ratio (OR): 2.26; P &lt; 0.001] and bilobectomy (OR : 2.28, P &lt; 0.001). Age &lt;60 years (OR: 0.71, P = 0.013), female sex (OR: 0.54, P &lt; 0.001) and VATS (0.64, P &lt; 0.001) were associated with decreased risk. Neoadjuvant treatment was not associated with increased risks of cardiopulmonary complications (OR: 1.05; P = 0.664). Compared to open thoracotomy, VATS was associated with significantly decreased overall morbidity (30.4% vs 41.7%, P = 0.006) and length of stay (median: 5 days vs 8 days; P &lt; 0.001). Sleeve lobectomies can be safely performed after neoadjuvant treatment. The VATS approach fosters shorter length of stay and decreased morbidity.
