Minimally invasive technique facilitates early extubation after cardiac surgery: a single-center retrospective study

BackgroundPostoperative time to extubation plays a role in prognosis after heart valve surgery; however, its exact impact has not been clarified. This study compared the postoperative outcomes of minimally invasive surgery and conventional sternotomy, focusing on early extubation and factors influencing prolonged mechanical ventilation.MethodsData from 744 patients who underwent heart valve surgery at the Zhejiang Provincial People’s Hospital between August 2019 and June 2022 were retrospectively analyzed. The outcomes in patients who underwent conventional median sternotomy (MS) and minimally invasive (MI) video-assisted thoracoscopic surgery were compared using inverse probability of treatment weighting (IPTW) and Kaplan–Meier curves. Clinical data, including surgical data, postoperative cardiac function, postoperative complications, and intensive care monitoring data, were analyzed.ResultsAfter propensity score matching and IPTW, 196 cases of conventional MS were compared with 196 cases of MI video-assisted thoracoscopic surgery. Compared to patients in the conventional MS group, those in the MI video-assisted thoracoscopic surgery group in the matched cohort had a higher early postoperative extubation rate (P < 0.01), reduced incidence of postoperative pleural effusion (P < 0.05), significantly shorter length of stay in the intensive care unit (P < 0.01), shorter overall length of hospital stay (P < 0.01), and lower total cost of hospitalization (P < 0.01).ConclusionsSuccessful early tracheal extubation is important for the intensive care management of patients after heart valve surgery. The advantages of MI video-assisted thoracoscopic surgery over conventional MS include significant reductions in the duration of use of mechanical ventilation support, reduced length of intensive care unit stay, reduced total length of hospitalization, and a favorable patient recovery rate.

251. THE COMPARISON OF UNIPORTAL VERSUS MULTIPORTAL VIDEO-ASSISTED THORACIC SURGERY FOR ESOPHAGEAL CANCER: A PROPENSITY-WEIGHTED ANALYSIS

Abstract Background Uniportal video-assisted thoracoscopic surgery (VATS) has been widely used, however, there are few studies on uniportal VATS for esophagectomy. Methods Data from patients with clinical stage T1–3/N0/M0 thoracic esophageal cancer who underwent surgery between January 2017 and December 2020 were retrospectively collected and retrospectively analyzed. Inverse probability of treatment weighting (IPTW) analysis was performed to assess the outcomes. Results Overall, 55 patients who underwent uniportal, and 212 patients who underwent multiportal, VATS were identified. Surgery-related postoperative complications (Clavien-Dindo grades 1–2) occurred less frequently after uniportal than multiportal VATS in both crude and IPTW models (10.1% versus 28.8%, respectively; P = 0.018). The median postoperative length of stay was 9 (9–10) days in the uniportal VATS and 10 (9–14) days in the multiportal VATS group (P = 0.006 after IPTW). Upon IPTW analysis, in uniportal and multiportal VATS groups, the rates of pneumonia (grades 1-2) were 7.3% and 23.2% (P = 0.037). The visual analog scale (VAS) was administered on postoperative first 7 days and were significantly lower in the uniportal VATS group (P &amp;lt; 0.001). No surgical mortality was observed in the uniportal VATS group, and the survival benefit between the two groups was comparable before (P = 0.320) and after IPTW (P = 0.824). Conclusion Uniportal VATS for esophagectomy resulted in a lower rate of postoperative complications with less postoperative pain, and is practical for treating patients with esophageal cancer.

The role of the early video-assisted thoracoscopic surgery in children with pleural empyema.

Pleural empyema (PE) is a collection of purulent material in the pleural space. PE's management in children is a challenge and an inappropriate diagnostic-therapeutic work up can lead to serious short and long-term complications. The aim of this study is to define the correct timing to approach a pediatric PE by video-assisted thoracoscopic surgery (VATS). A retrospective observational study was conducted including pediatric patients who underwent video-assisted thoracoscopy for pleural empyema between May 2005 and September 2022. 62 patients were subjected to VATS for PE (32 in Group Early VATS, 30 in Group Late VATS). It emerged that the elapsed period between the onset of symptoms and surgery correlates in a statistically significant way with the post-operative stay in intensive care (z score 4.3 and p value < 0.0001) and the analysis between early VATS, late VATS and postoperative hospitalization showed a statistically significant reduction of the post-operative hospitalization in the early VATS groups (p value < 0.02). VATS resulted to be safe and effective for the treatment of PE in children, and an early minimally invasive thoracoscopic intervention (early VATS) correlates with better outcomes, specifically in terms of intensive care hospitalization and overall hospitalization.

Advantages of robot-assisted resection of large mediastinal tumors: a single-center preliminary study.

Current study aims to assess the safety and efficacy of robot-assisted thoracoscopic surgery (RATS) for sizable mediastinal masses with a minimum diameter ≥6cm, compared with video-assisted thoracoscopic surgery (VATS) and open surgery. This study enrolled 130 patients with mediastinal tumors with no less than 6 cm diameter in Zhongnan Hospital, Wuhan University, including 33 patients who underwent RATS, 52 patients who underwent VATS and 45 patients who underwent open surgery. After classifying based on mass size and whether it has invaded or not, we compared their clinical characteristics and perioperative outcomes. There was no significant difference in age, gender, mass size, myasthenia gravis, mass location, pathological types (p>0.05) in three groups. Patients undergoing open surgery typically presenting at a more advanced stage (p<0.05). No obvious difference was discovered in the average postoperative length of stay, operation duration, chest tube duration and average postoperative day 1 drainage output between RATS group and VATS group (p>0.05), while intraoperative blood loss in RATS group was significantly lower than VATS group (p=0.046). Moreover, the postoperative length of stay, operation duration, chest tube duration and intraoperative blood loss in RATS group were significantly lower than open surgery group (p<0.001). RATS is a secure and efficient approach for removing large mediastinal masses at early postoperative period. In comparison with VATS, RATS is associated with lower intraoperative blood loss. Compared with open surgery, RATS is also associated with shorter postoperative length of stay, operation duration, chest tube duration and intraoperative blood loss.

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.

Outcomes of single- versus multi-port video-assisted thoracoscopic surgery: Data from a multicenter randomized controlled trial of video-assisted thoracoscopic surgery versus thoracotomy for lung cancer

ObjectivesSurgery through a single port may be less painful because access is supplied by 1 intercostal nerve or more painful because multiple instruments are used in 1 port. We analyzed data collected from the video-assisted thoracoscopic surgery group of a randomized controlled trial to compare differences in pain up to 1 year. MethodsGroups were compared in a prespecified exploratory analysis using direct (regression) and indirect comparison (difference with respect to thoracotomy). In-hospital visual analogue scale pain scores were used, and analgesic ratios were calculated. After discharge, pain was evaluated using European Organization for Research and Treatment of Cancer Quality of Life Questionnaires-Core 30 scores up to 1 year. ResultsFrom July 2015 to February 2019, we randomized 503 participants. After excluding 50 participants who did not receive lobectomy, surgery was performed using a single port in 42 participants (predominately by a single surgeon), multiple ports in 166 participants, and thoracotomy in 245 participants. No differences were observed in-hospital between single- and multiple-port video-assisted thoracoscopic surgery when modeled using a direct comparison, mean difference of −0.24 (95% CI, −1.06 to 0.58) or indirect comparison, mean difference of −0.33 (−1.16 to 0.51). Mean analgesic ratio (single/multiple port) was 0.75 (0.64 to 0.87) for direct comparison and 0.90 (0.64 to 1.25) for indirect comparison. After discharge, pain for single-port video-assisted thoracoscopic surgery was lower than for multiple-port video-assisted thoracoscopic surgery (first 3 months), and corresponding physical function was higher up to 12 months. ConclusionsThere were no consistent differences for in-hospital pain when lobectomy was undertaken using 1 or multiple ports. However, better pain scores and physical function were observed for single-port surgery after discharge.

Video-Assisted Thoracoscopic Surgery Versus Thoracotomy Following Neoadjuvant Immunochemotherapy in Resectable Stage III Non-Small Cell Lung Cancer Among Chinese Populations: A Multi-Center Retrospective Cohort Study

BackgroundImmune checkpoint inhibitors have revolutionized non-small cell lung cancer (NSCLC) treatment but may pose greater technical challenges for surgery. This study aims to assess the feasibility and oncological effectiveness of video-assisted thoracoscopic surgery (VATS) for resectable stage III NSCLC after neoadjuvant immunochemotherapy. MethodsInitial stage IIIA-IIIB NSCLC patients with neoadjuvant immunochemotherapy undergoing either VATS or open lobectomy at 6 medical centers during 2019-2023 were retrospectively identified. Perioperative outcomes and 2-year survival was analyzed. Propensity-score matching (PSM) was employed to balance patient baseline characteristics. ResultsAmong the total 143 patients, PSM yielded 62 cases each for VATS and OPEN groups. Induction-related adverse events were comparable between the 2 groups. VATS showed a 14.5% conversion rate. Notably, VATS decreased numeric rating scales for postoperative pain, shortened chest tube duration (5[4-7] vs. 6[5-8] days, P = .021), reduced postoperative comorbidities (21.0% vs. 37.1%, P = .048), and dissected less N1 lymph nodes (5[4-6] vs. 7[5-9], P = .005) compared with thoracotomy. Even when converted, VATS achieves perioperative outcomes equivalent to thoracotomy. Additionally, over a median follow-up of 29.5 months, VATS and thoracotomy demonstrated comparable 2-year recurrence-free survival (77.20% vs. 73.73%, P = .640), overall survival (87.22% vs. 88.00%, P = .738), cumulative incidences of cancer-related death, and recurrence patterns. Subsequent subgroup comparisons and multivariate Cox analysis likewise revealed no statistical difference between VATS and thoracotomy. ConclusionVATS is a viable and effective option for resectable stage III NSCLC patients following neoadjuvant immunochemotherapy, leading to decreased surgical-related pain, earlier chest tube removal, reduced postoperative complications, and similar survival outcomes compared to thoracotomy.

Outcomes of robot-assisted versus video-assisted mediastinal mass resection during the initial learning curve

To compare the learning curve of mediastinal mass resection between robot-assisted surgery and thoracoscopic surgery. Retrospective perioperative data were collected from 160 mediastinal mass resection cases. Data included 80 initial consecutive video-assisted thoracoscopic surgery (VATS) resection cases performed from February 2018 to February 2020 and 80 initial consecutive robotic-assisted thoracic surgery (RATS) resection cases performed from March 2020 to March 2023. All cases were operated on by a thoracic surgeon. The clinical characteristics and perioperative outcomes of the two groups were compared. The operation time in both the RATS group and VATS group was analyzed using the cumulative sum (CUSUM) method. Based on this method, the learning curves of both groups were divided into a learning period and mastery period. The VATS group and the RATS group crossed the inflection point in the 27th and 21st case, respectively. Subsequently, we found that the learning period was longer than the mastery period with statistically significant differences in terms of the operating time, and postoperative hospital stay in the VATS group and the RATS group. A certain amount of VATS experience can shorten the learning curve for RATS.

Evaluation of myocardial work changes after lung resection-the significance of surgical approach: an echocardiographic comparison between VATS and thoracotomy.

Considering the controversial benefits of video-assisted thoracoscopic surgery (VATS), we intended to evaluate the impact of surgical approach on cardiac function after lung resection using myocardial work analysis. Echocardiographic data of 48 patients (25 thoracotomy vs. 23 VATS) were retrospectively analyzed. All patients underwent transthoracic echocardiography (TTE) within 2 weeks before and after surgery, including two-dimensional speckle tracking and tissue Doppler imaging. No notable changes in left ventricular (LV) function, assessed mainly using the LV global longitudinal strain (GLS), global myocardial work index (GMWI), and global work efficiency (GWE), were observed. Right ventricular (RV) TTE values, including tricuspid annular plane systolic excursion (TAPSE), tricuspid annular systolic velocity (TASV), right ventricular global longitudinal strain (RVGLS), and RV free-wall GLS (RVFWGLS), indicated greater RV function impairment in the thoracotomy group than in the VATS group [TAPSE(mm) 17.90 ± 3.80 vs. 21.00 ± 3.48, p = 0.006; d = 0.84; TASV(cm/s): 12.40 ± 2.90 vs. 14.70 ± 2.40, p = 0.004, d = 0.86; RVGLS(%): - 16.00 ± 4.50 vs. - 19.40 ± 2.30, p = 0.012, d = 0.20; RVFWGLS(%): - 11.50 ± 8.50 vs. - 18.31 ± 5.40, p = 0.009, d = 0.59; respectively]. Unlike RV function, LV function remained preserved after lung resection. The thoracotomy group exhibited greater RV function impairment than did the VATS group. Further studies should evaluate the long-term impact of surgical approach on cardiac function.

Video-assisted thoracoscopic surgery for non-cystic fibrosis bronchiectasis in children.

Pediatric bronchiectasis is a common respiratory disease in children. The use of video-assisted thoracoscopic surgery (VATS) for its treatment remains controversial. The objective of our study was to compare and analyze the clinical efficacy of thoracoscopic surgery and thoracotomy in the treatment of pediatric bronchiectasis and summarize the surgical treatment experience of VATS in children with bronchiectasis. Retrospective single-center cohort study. A retrospective analysis was conducted on the clinical data of 46 pediatric patients who underwent surgery with bronchiectasis at the Children's Hospital of Chongqing Medical University from May 2015 to May 2023. The patients were divided into two groups: the VATS group (25 cases) and the thoracotomy group (21 cases). Comparative analysis was performed on various parameters including basic clinical data, surgical methods, operation time, intraoperative blood loss, transfusion status, postoperative pain, postoperative mechanical ventilation time, chest tube drainage time, length of hospital stay, incidence of complications, and follow-up information. There were no statistically significant differences between the two groups of patients in terms of age, weight, gender, etiology, duration of symptoms, site of onset, and comorbidities (p > 0.05). The operation time in the VATS group was longer than that in the thoracotomy group (p < 0.001). However, the VATS group had better outcomes in terms of intraoperative blood loss, transfusion status, postoperative pain, postoperative mechanical ventilation time, chest tube drainage time, and length of hospital stay (p < 0.05). The incidence of postoperative complications in the VATS group was lower than that in the thoracotomy group, although the difference was not statistically significant (p = 0.152). Follow-up data showed no statistically significant difference in the surgical treatment outcomes between the two groups (p = 0.493). The incidence of complications and mortality in surgical treatment of bronchiectasis is acceptable. Compared with thoracotomy surgery, VATS has advantages such as smaller trauma, less pain, faster recovery, and fewer complications. For suitable pediatric patients with bronchiectasis, VATS is a safe and effective surgical method.

Analyzing robotic surgery impact on recovery quality & emotions

BackgroundThe objective of this study is to investigate the postoperative recovery quality and emotional status of patients with non-small cell lung cancer (NSCLC) who underwent robot-assisted and video-assisted thoracoscopic surgery using the 15-item Quality of Recovery (QoR-15) scale and to analyze the correlation. MethodsWe collected clinical data from 320 patients with NSCLC who underwent lobectomy using either robot-assisted thoracoscopic surgery (RATS) or video-assisted thoracoscopic surgery (VATS) at our center from January 2021 to December 2022. We compared perioperative parameters and followed up after the operation using the QoR-15 scale to objectively assess the quality of postoperative recovery and physical and emotional status. ResultsApart from a notable distinction in anesthesia time, no significant differences were observed in other general data. Notably, the overall recovery rate for patients in the RATS group surpassed that of the VATS group (P < 0.05). Specifically, the recovery rates in the RATS group were significantly superior to those in the VATS group across nociceptive factors, emotional factors, activities of daily living, physiological factors, and cognitive ability (P < 0.05). Spearman correlation analysis between surgical methods and various indicators of the QoR-15 scale showed significant correlations between surgical methods (P < 0.05). ConclusionThe QoR-15 scale is a valuable tool for assessing the postoperative recovery quality in lung cancer patients. The RATS plays a significant role in promoting the swift postoperative recovery of patients and demonstrates excellent efficacy, safety, and reliability.

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.

PP94 Robotic-Assisted Thoracoscopic Surgery Versus Video-Assisted Thoracoscopic Surgery And Open Thoracotomy: A Systematic Review And Meta-Analysis

IntroductionRobot-assisted surgery is one of the minimally invasive surgical approaches that has been increasingly utilized across a wide range of surgeries. However, there is limited evidence of robotic-assisted thoracic surgery (RATS) for patients with lung cancer. This study aims to evaluate the safety and effectiveness of RATS in lung cancer patients compared with video-assisted thoracoscopic surgery (VATS) and open thoracotomy.MethodsA comprehensive search for studies that compared RATS versus VATS or open thoracotomy published until 12 April 2022, was conducted. Two review authors independently assessed studies for inclusion and risk of bias, and extracted data. We used results of reported perioperative outcomes, oncological outcomes, and survival outcomes. When more than two studies contributed data, meta-analyses were performed.ResultsFour randomized controlled trials (RCT) were included. Firstly, three RCTs comparing RATS with VATS were identified. Compared with the VATS group, the RATS group had significantly lower blood loss, more harvested lymph nodes and lymph node stations. However, there were no significant differences in operative time, transfusion rates, hospital stay, drainage duration, reoperation, readmission, postoperative pain, and postoperative complications. Survival outcomes were not reported. Secondly, one RCT comparing RATS with open thoracotomy was identified. Compared with open thoracotomy group, the RATS group had significantly lower blood loss, less postoperative pain, and shorter chest drainage duration. On the other hand, there were no significant differences in operative time, hospital stay, postoperative complications, number of harvested lymph nodes and lymph node stations, and survival outcomes (disease-free survival, overall survival).ConclusionsEvidence on the effectiveness and safety of RATS compared with VATS or open thoracotomy for lung cancer is of low certainty, but we suggest that RATS is a feasible and safe alternative to conventional thoracic surgeries for lung cancer patients on the basis of current data. Additionally, more and better studies are required to provide evidence on the benefits and cost-effectiveness of RATS.

Effect of da Vinci robot versus thoracoscopic surgery on lung function and oxidative stress levels in NSCLC patients: a propensity score-matched study.

To evaluate the short-term efficacy, lung function, and oxidative stress levels between the robotic-assisted thoracoscopic surgery (RATS) and video-assisted thoracoscopic surgery group (VATS) for non-small cell lung cancer (NSCLC). We conducted a retrospective cohort study, selecting 248 NSCLC patients who underwent minimally invasive lobectomy at the Department of Thoracic Surgery, Gansu Provincial People's Hospital, from August 2019 to February 2023. There were 105 patients in the RATS group and 143 patients in the VATS group. The patients in the two groups were subjected to 1:1 propensity score matching analysis (PSM), and the perioperative indicators were recorded. The levels of oxidative stress factors (superoxide dismutase, SOD; malondialdehyde, MDA) and inflammatory factors were measured 1day before surgery and 3days after surgery, respectively. Pulmonary function and patient quality of life were measured at 1day preoperatively and 3months postoperatively. There are 93 patients in each group after PSM. Compared to the VATS group, the RATS group had shorter operation time, less intraoperative blood loss, greater number and groups of lymph nodes cleared, and shorter postoperative hospital stay. The SOD level in the RATS group was higher and the MDA level was lower than that in the VATS group after surgery. Postoperative inflammatory cytokine levels were less elevated in the RATS group than in the VATS group. At 3months postoperatively, FVC%, FEV1%, and GQOLI-74 scores were higher in the RATS group than in the VATS group. Compared to VATS lobectomy, RATS lobectomy has the advantages of shorter operative time, lesser bleeding, more lymph node dissection, faster postoperative recovery, and lesser impact on postoperative lung function. It is also capable of reducing the postoperative oxidative stress and inflammatory response, which can improve patients' quality of life.

Results of video-assisted thoracoscopic surgery versus thoracotomy for lung cancer in a mixed practice medium-volume hospital: a propensity-matched study.

The aim of this study was to compare the short- and long-term results of video-assisted thoracoscopic surgery (VATS) and thoracotomy for non-small-cell lung cancer in a medium-volume centre, where cardiothoracic surgeons perform both cardiac and general thoracic surgery. The primary outcome of interest was 5-year overall survival and disease-specific survival. Secondary outcomes were short-term postoperative complications, length of hospital stay and lymph node yield. This was a retrospective cohort study including 670 lung cancer patients undergoing VATS (n = 207) or open surgery (n = 463) with a curative intent in Oulu University Hospital between the years 2000-2020. Propensity score matching was implemented with surgical technique as the dependent and age, sex, Charlson comorbidity index, pulmonary function, pathological stage, histological type and the year of the operation as covariates resulting in 127 pairs. In the propensity-matched cohort, 5-year overall survival was 64.3% after VATS and 63.2% after thoracotomy (P = 0.969). Five-year disease-specific survival was 71.6% vs 76.2% (P = 0.559). There were no differences in overall (34.6% vs 44.9%, p = 0.096) or major postoperative complications (8.7% vs 14.2%, P = 0.167) between the study groups. The average length of hospital stay was shorter (5.8 vs 6.6 days, P = 0.012) and the median lymph node yield was lower (4.0 vs 7.0, P < 0.001) in the VATS group compared to the thoracotomy group. According to this study, the long-term results of lung cancer surgery in a mixed practice are comparable between VATS and open surgery.

Operative outcomes and middle-term survival of robotic-assisted lung resection for clinical stage IA lung cancer compared with video-assisted thoracoscopic surgery

BackgroundDespite limited published evidence, robotic-assisted thoracoscopic surgery (RATS) for anatomic lung resection in early-stage lung cancer continues growing. The aim of this study is to evaluate its safety and oncologic efficacy compared to video-assisted thoracoscopic surgery (VATS). MethodsSingle-centre retrospective study of all patients with resected clinical stage IA NSCLC who underwent RATS or VATS anatomic lung resection from June 2018 to January 2022. RATS and VATS cases were matched by propensity scoring (PSM) according to age, sex, histology, and type of resection. Short-term outcomes were compared, and the Kaplan-Meier method and log-rank test were used to evaluate the overall survival (OS) and disease-free survival (DFS). Results321 patients (94 RATS and 227 VATS cases) were included. After PSM, 94 VATS and 94 RATS cases were compared. Demographics, pulmonary function, and comorbidity were similar in both groups. Overall postoperative morbidity was comparable for RATS and VATS cases (20.2% vs 25.5%, P = 0.385, respectively). Pathological nodal upstaging was similar in both groups (10.6% in RATS and 12.8% in VATS). During the 3.5-year follow-up period (median: 29 months; IQR: 18–39), recurrence rate was 6.4% in RATS group and 18.1% in the VATS group (P = 0.014). OS and DFS were similar in RATS and VATS groups (log rank P = 0.848 and P = 0.117, respectively). ConclusionRATS can be performed safely in patients with early-stage NSCLC. For clinical stage IA disease, robotic anatomic lung resection offers better oncologic outcomes in terms of recurrence, although there are no differences in OS and DFS compared with VATS.

Surgery for bronchiectasis-destroyed lung: feasibility of video-assisted thoracoscopic surgery, and surgical outcomes.

To provide the experience of surgical treatment for bronchiectasis-destroyed lung (BDL) and evaluate the feasibility of video-assisted thoracoscopic surgery (VATS). BDL patients underwent surgical treatment between January 2013 and June 2018 were included. Logistic regression was performed to assess factors for major complications, and Cox's regression was performed to assess factors affected symptomatic outcome. Totally, 143 patients were treated by VATS (n = 64) and thoracotomy (n = 79). Nine (14.1%) cases scheduled for VATS were converted to thoracotomy for dense adhesions (n = 6) and frozen hilum (n = 3). The VATS group had a median chest tube duration, hospitalization and a time of returning to full activity of 4 days, 5 days and 1.5 months, respectively. Major complications occurred in 28 (19.6%) of all patients, 50.0% after pneumonectomy and 13.4% after lobectomy/extensive lobectomy. Multivariable analysis identified pneumonectomy [odds ratio, 3.64; 95% confidence interval (CI), 1.18-11.21] as a significant predictor for major complications. Overall, 141 (98.6%) patients benefitted from surgery (completely asymptomatic, n = 109; acceptable alleviation, n = 32). Thirty-four patients experienced relapse of the disease, including 13 with productive cough, 11 with haemoptysis and 10 with recurrent infections. Pseudomonas aeruginosa infection [hazard ratio (HR), 3.07; 95% CI, 1.38-6.83] and extent of remanent bronchiectatic areas (HR, 1.03; 95% CI, 1.00-1.05) were independent risk factors for shorter relapse free interval. VATS for BDL is feasible in well-selected patients. Pneumonectomy increased the risk of postoperative major complications. Removing all BDL lesions contributed to satisfactory prognosis.

Robot versus video-assisted thoracoscopic thymectomy for large thymic epithelial tumors: a propensity-matched analysis

BackgroundBoth video-assisted thoracoscopic surgery (VATS) thymectomy and robot-assisted thoracoscopic surgery (RATS) thymectomy have been suggested as technically sound approaches for early-stage thymic epithelial tumors. However, the choice of VATS or RATS thymectomy for large and advanced thymic epithelial tumors remains controversial. In this study, the perioperative outcomes of VATS and RATS thymectomy were compared in patients with large thymic epithelial tumors (size ≥5.0 cm).MethodsA total of 113 patients with large thymic epithelial tumors who underwent minimally invasive surgery were included. Sixty-three patients underwent RATS, and 50 patients underwent VATS. Patient characteristics and perioperative variables were compared.ResultsCompared with the VATS group, the RATS group experienced a shorter operation time (median: 110 min vs.130 min; P < 0.001) and less blood loss (30.00 ml vs. 100.00 ml, P < 0.001). No patients in the RATS group needed conversion to open surgery, but in the VATS series, five patients required conversion to open procedures (0% vs. 14.29%, P = 0.054). The rate of concomitant resection in the RATS group was similar to that in the VATS group (11.43% vs. 5.71%; P = 0.673). There was no significant difference between the two groups in the duration of chest tube (P = 0.587), postoperative complications (P = 1.000), and the duration of postoperative hospital stay (P = 0.141).ConclusionFor large thymic epithelial tumors, RATS thymectomy can be performed safely and effectively in a radical fashion. Due to the advanced optics and precise instrument control, concomitant resections can be easily achieved in larger thymic epithelial tumors using the robotic approach.

Differential Outcomes of VATS and Open Surgery in Lung Cancer Patients with Antecedent Oncological Diagnoses.

Primary lung cancer is a devastating disease with high morbidity and mortality rates. Patients with a previous oncological history may present with multiple comorbidities, unique clinical features, and unique outcomes after surgical intervention for primary lung cancer. This study aimed to compare the clinical features and outcomes of patients with a previous oncological history who underwent video-assisted thoracoscopic surgery (VATS) or open surgery (OS) for primary lung cancer. A retrospective analysis was conducted on 84 patients with a previous oncological history who underwent surgical intervention for primary lung cancer between January 2018 and January 2023. Among them, 55 patients underwent VATS, while 29 patients underwent OS. Demographic and clinical characteristics, perioperative variables, and postoperative outcomes of the two surgical groups were collected and compared. Most of the 84 patients were women (58.4%) with a high smoking prevalence (44.1%) and a median of 32.3 packs-year. The patients' histories were most predominant for gynecologic cancers (44.4%) and colorectal cancers (18.6%). The results showed that the VATS group had a significantly shorter median hospital stay than the OS group (6.0 days vs. 12.0 days, p-value < 0.001). Additionally, the VATS group had lower incidences of air leaks 24 h post-surgery (12.7% vs. 48.3%, p-value < 0.001) and intractable pain (3.6% vs. 17.2%, p-value = 0.031), as well as significantly lower operative times (270 min vs. 350 min, p-value = 0.046). However, there were no significant differences between the VATS and OS groups in overall survival (log-rank p-value = 0.447). Furthermore, although the 3-month survival was significantly higher in the VATS group (98.2% vs. 79.3%, p-value = 0.003), only one patient from the VATS group (1.8%) and two patients from the OS group (6.9%) were still alive five years after the intervention. In conclusion, VATS is a safe and effective surgical option for patients with a previous oncological history who require surgical intervention for primary lung cancer, with shorter operative times, shorter hospital stays, and lower rates of complications compared to those of OS patients, without compromising oncological outcomes. Nevertheless, both surgical options failed to improve the 5-year survival rate, probably due to the high prevalence of comorbidities and the burden of previous cancer in this population.
