Efficacy of robot-assisted thoracoscopic surgery for managing thymoma recurrence following sternotomy: a case report.

This report addresses the management strategy and effectiveness of robot-assisted thoracoscopic surgery (RATS) for treating local recurrence of thymoma, a condition often complicated by severe adhesions and limited data on re-operation following median sternotomy. We report about a 43-year-old man with thymoma recurrence 4 years after thymothymectomy via a median sternotomy. Follow-up computed tomography revealed a nodule adjacent to the left brachiocephalic vein, indicating possible thymoma recurrence. Thus, re-operation was performed using a left-sided approach via RATS with an artificial pneumothorax. The manipulation space was secured with an artificial pneumothorax, and multidirectional manipulation using RATS demonstrated good efficacy. Collectively, this case highlights the efficacy of RATS as a viable approach for managing thymoma recurrence in mediastinal locations, particularly when sternotomy is complicated by severe adhesions.

Evolution of Three-Dimensional Computed Tomography Imaging in Thoracic Surgery.

Radiologic reconstruction technology allows the wide use of three-dimensional (3D) computed tomography (CT) images in thoracic surgery. A minimally invasive surgery has become one of the standard therapies in thoracic surgery, and therefore, the need for preoperative and intraoperative simulations has increased. Three-dimensional CT images have been extensively used, and various types of software have been developed to reconstruct 3D-CT images for surgical simulation worldwide. Several software types have been commercialized and widely used by not only radiologists and technicians, but also thoracic surgeons. Three-dimensional CT images are helpful surgical guides; however, in almost all cases, they provide only static images, different from the intraoperative views. Lungs are soft and variable organs that can easily change shape by intraoperative inflation/deflation and surgical procedures. To address this issue, we have developed a novel software called the Resection Process Map (RPM), which creates variable virtual 3D images. Herein, we introduce the RPM and its development by tracking the history of 3D CT imaging in thoracic surgery. The RPM could help develop a real-time and accurate surgical navigation system for thoracic surgery.

Pulmonary presentation and coil marcation of dirofilaria lung coin nodes - case report.

Clinicians face significant diagnostic challenges when dealing with nodal lesions of the lung. The majority of lung nodules are benign; however, a significant number can be cancerous. Dirofilaria infestation should also be considered in the differential diagnosis of nodal lung lesions. Most patients with Dirofilaria infestation are asymptomatic. To determine the etiology of nodal lung infiltrations, procedures like radiological imaging, bronchoscopy, endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA), transthoracic biopsy (TTB), tumor markers, nonspecific serological tests, or surgical removal of the lung coin lesions can be performed. Coil marking of the smaller lung lesions under computed tomography (CT) guidance is a helpful tool in determining the position and localization of the nodal lung lesions. Video-assisted thoracoscopic surgery (VATS) or robot-assisted thoracoscopic surgery (RATS) wedge resection is a diagnostic and therapeutic method of choice. No additional treatment of Dirofilaria other than wedge resection of the lung is necessary.

A comparison of three-port and four-port Da Vinci robot-assisted thoracoscopic surgery for lung cancer: a retrospective study.

BACKGROUND: At present, research comparing the short-term postoperative outcomes of anatomical resection in lung cancer under different ports of da Vinci robot-assisted surgery is insufficient. This report aimed to compare the outcomes of three-port and four-port da Vinci robot-assisted thoracoscopic surgery for radical dissection of lung cancer. METHODS: 171 consecutive patients who presented to our hospital from January 2020 to October 2021 with non-small cell lung cancer and treated with da Vinci robot-assisted thoracoscopic surgery for radical resection of lung cancer were retrospectively collected and divided into the three-port group (n = 97) and the four-port group (n = 74). The general clinical data, perioperative data and life quality were individually compared between the two groups. RESULTS: All the 171 patients successfully underwent surgeries. Compared to the four-port group, the three-port group had comparable baseline characteristics in terms of age, sex, tumor location, tumor size, history of chronic disease, pathological type, and pathological staging. The three-port group also had shorter operation time, less intraoperative blood loss, lower chest tube drainage volume, shorter postoperative hospitalization stay durations, but showed no statistically significant difference (P > 0.05). Postoperative 24, 48 and 72 h visual analogue scale pain scores were lower in the three-port group (p < 0.001). No significant difference was observed between the two groups in the hospitalization costs (P = 0.664), number or stations of total lymph node dissected (p > 0.05) and postoperative respiratory complications (P > 0.05). CONCLUSIONS: The three-port robot-assisted thoracoscopic surgery is safe and effective and took better outcomes than the four-port robot-assisted thoracoscopic surgery in non-small cell lung cancer.

Postoperative leukocyte counts as a surrogate for surgical stress response in matched robot- and video-assisted thoracoscopic surgery cohorts of patients: A preliminary report.

The objective is to preliminary evaluated postoperative leukocyte counts as a surrogate for the surgical stress response in NSCLC patients who underwent RATS or VATS for further prospective analyses with proper assessment of surgical stress response and tissue trauma. We retrospectively analyzed patients with stageI-IIIA NSCLC who underwent RATS or VATS at a hospital between 8 May 2020 and 31 December 2021. Analysis of leukocytes (including neutrophils and lymphocytes) and albumin on postoperative days (PODs) 1 and 3 in patients with NSCLC treated with RATS or VATS after propensity score matching (PSM). In total, 1824 patients (565 RATS and 1259 VATS) were investigated. The two MIS groups differed significantly with regard to operative time (p < 0.001), chronic lung disease (p < 0.001), the type of pulmonary resection (p < 0.001), the excision site of lobectomy (p = 0.004), and histology of the tumor (p = 0.028). After PSM, leukocyte and neutrophil levels in the RATS group were lower than those in the VATS group on PODs 1 and 3, with those on POD 3 (p < 0.001) being particularly notable. While lymphocyte levels in the RATS group were significantly lower than those in the VATS group only at POD 1 (p = 0.016). There was no difference in albumin levels between the RATS and VATS groups on PODs 1 and 3. The surgical stress response and tissue trauma was less severe in NSCLC patients who underwent RATS than in those who underwent VATS, especially reflected in the neutrophils of leukocytes.

Efficacy of Da Vinci Robot-assisted Thoracoscopic Surgery in Children With Congenital Cystic Adenomatiod Malformation.

BACKGROUND: Surgical intervention is advisable for both asymptomatic and symptomatic CCAM children. This study aims to compare and analyze the efficacy of thoracoscopic and Da Vinci robot-assisted procedures in the management of CCAM among pediatric patients. METHODS: The clinical data of 188 pediatric patients diagnosed with CCAM and admitted to the Children's Hospital, Zhejiang University School of Medicine, from April 2019 to April 2023 were retrospectively analyzed. The Clavien-Dindo classification was employed for the systematic categorization of postoperative complications. RESULTS: The demographic and clinical characteristics of the patients were comparable between the two groups. Postoperative outcomes, such as the chest tube indwelling rate (92.6% vs 36.2%, p < 0.001∗), chest tube duration (2.0 (2.0-3.0) days vs 1.0 (1.0-2.0) days, p < 0.001∗), and length of postoperative hospital stay (6.0 (5.0-7.0) days vs 5.0 (5.0-6.0) days, p < 0.001∗), favored RATS over VATS. Additionally, there was no significant difference in complications between the two group, but the p-value is in a critical state. Ⅲa complications (mainly composed of postoperative thoracentesis procedures) manifesting as a higher rate in the RATS, nearly double that observed in the VATS. CONCLUSIONS: Robot-assisted thoracoscopic lung resection is demonstrated to be safe and feasible, with notable advantages in short-term postoperative clinical outcomes. Nevertheless, the practicality and long-term benefits of this technique necessitate further refinement and dedicated study. LEVEL OF EVIDENCE: LEVEL III.

Case Report: Uniportal robot-assisted thoracoscopic double-sleeve lobectomy after neoadjuvant immunotherapy.

Minimally invasive thoracic surgery, including video-assisted thoracoscopic surgery and robot-assisted thoracoscopic surgery, has been proven to have an advantage over open thoracotomy with less pain, fewer postoperative complications, faster discharge, and better tolerance among elderly patients. We introduce a uniportal robot-assisted thoracoscopic double-sleeve lobectomy performed on a patient following neoadjuvant immunotherapy. Specialized instruments like customized trocars with a reduced diameter, bulldog clamps, and double-needle sutures were utilized to facilitate the maneuverability through the single incision. This technique integrates the merits of multiport robot-assisted thoracic surgery with uniportal video-assisted thoracoscopic surgery.

Intraoperative robotic surgical system-related problems in robot-assisted thoracoscopic surgery.

BACKGROUND: Malfunctions of robotic instruments during robotic surgery are well known to occur; however, detailed reports on the inherent problems associated with robotic instruments and robotic surgical systems are scarce. The objective of this study was to retrospectively investigate the intraoperative problems associated with robotic surgical systems and robotic instruments. MATERIALS AND METHODS: This was a single-center retrospective study. Between April 2012 and December 2022, 544 patients with consecutive lung malignancies and/or mediastinal tumors underwent robot-assisted thoracoscopic surgery. Among these, 15 cases had intraoperative problems associated with the robotic surgical system. Human error was defined as a problem caused by the incorrect operation of the robotic surgical system and human factors as problems in which the robotic surgical system stopped owing to damage to the instruments of the robotic surgical system or the self-diagnosis of the robotic surgical system. We retrospectively investigated the causes of intraoperative problems in these cases. RESULTS: There were 4 cases (0.7%) with problems related to the robotic surgical system, 2 of which were human errors, and 11 (2.0%) with problems related to robotic surgical instruments, 6 of these were related to instruments and 5 were related to robotic staplers. Five of these were related to human factors. CONCLUSION: Teams performing robot-assisted thoracoscopic surgery should be familiar with the features of robotic surgical systems and various robotic devices, be aware of reported problems during robot-assisted thoracoscopic surgery, and be prepared for emergencies.

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.

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.

Analyzing robotic surgery impact on recovery quality & emotions.

Background: The 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. Methods: We 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. Results: Apart 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). Conclusion: The 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.

A comparative study of robot-assisted thoracoscopic surgery and conventional approaches for short-term outcomes of anatomical segmentectomy.

OBJECTIVES: Since anatomical segmentectomy requires meticulous dissection of the segmental pulmonary vessels and bronchus, robot-assisted thoracoscopic surgery (RATS) has been widely adopted in recent years. We investigated the usefulness of RATS segmentectomy by comparing perioperative outcomes with conventional approaches including open thoracotomy or video-assisted thoracoscopic surgery (VATS). We compared perioperative outcomes of segmentectomy between RATS and conventional approaches including open thoracotomy or video-assisted thoracoscopic surgery (VATS). METHODS: This single-institutional retrospective study comprised 231 patients with primary lung cancer who underwent segmentectomy by RATS or conventional approaches between January 2011 and December 2022. Surgical outcomes and postoperative complications were analyzed among patients whose background factors were adjusted by propensity score matching (PSM). RESULTS: Before PSM, there were significant differences in age, smoking status, and types of segmentectomy. After PSM, 126 patients (63 patients in each group) were included in this analysis. The RATS group had significantly shorter operative time (154 vs 210 min; p < 0.01), fewer bleeding amounts (10 vs 40 mL; p < 0.01), and shorter duration of chest drainage (2 vs 2 days; p = 0.04) than the conventional-approach group. There was no significant difference in the incidence of all complications; however, the incidence of postoperative pneumonia was significantly lower than in the conventional-approach group (p = 0.02). CONCLUSIONS: RATS segmentectomy is proposed to be useful. It was suggested that RATS segmentectomy may be useful with better perioperative results than the conventional approach. Further studies on oncological long-term outcomes and cost-benefit comparisons are needed.

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

BACKGROUND: 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). METHODS: 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 1 day before surgery and 3 days after surgery, respectively. Pulmonary function and patient quality of life were measured at 1 day preoperatively and 3 months postoperatively. RESULTS: 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 3 months postoperatively, FVC%, FEV1%, and GQOLI-74 scores were higher in the RATS group than in the VATS group. CONCLUSION: 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.

Perioperative outcomes comparison of robotic and video-assisted thoracoscopic thymectomy for thymic epithelial tumor: a single-center experience.

BACKGROUND: The advent of robot-assisted thoracoscopic surgery (RATS) has completely revolutionized the modality of thymectomy, which could reportedly achieve equivalent efficacy compared with a minimally invasive approach. This study was conducted to further compare the perioperative outcomes between these two modalities. METHODS: A retrospective single-center study that included patients receiving either a robotic or video-assisted thoracoscopic (VAT) thymectomy between February 2021 and January 2023 was conducted. All the patients were pathologically confirmed with thymic epithelial tumors. Clinical and pathological characteristics and perioperative outcomes were collected and compared between these two cohorts. RESULTS: A total of 190 patients were included in this study, with 61 (32.1%) and 129 (67.9%) receiving robotic and video-assisted thymectomy, respectively. The clinicopathological characteristics were not significantly different between these 2 groups. The size of the resected specimens in the RATS cohort was larger than the VATS cohort [median (IQR), 13.0 (8.0-16.0) vs. 9.0 (6.7-12.0) cm, p < 0.001], while the procedural duration was longer for the RATS group than its counterpart [median (IQR), 105 (85-143) vs. 85 (69-115) min, p = 0.001]. Moreover, no other significant difference was observed between these two groups. Since more than half of the robotic thymectomy was performed using a subxiphoid approach, a subgroup analysis was further conducted. Similarly, the robotic group through a subxiphoid approach harbored a longer procedural duration, and the size of the specimens obtained was larger than the VATS group [median (IQR), 14.0 (11.0-16.5) vs. 12.5 (8.5-15.0) cm, p = 0.061]. CONCLUSIONS: The early clinical efficacy of robotic thymectomy was proven comparable to the established VATS approach, and such a modality might have strength when obtaining larger specimens, which could contribute to improving long-term efficacy. Despite the longer procedural duration recorded in the early stage of conducting robotic thymectomy, further accumulation would help decrease the time.

Influencing Factors on Intersegmental Identification Adequacy in Segmentectomy with Intraoperative Indocyanine Green (ICG) Intravenous Administration.

Accurate identification of the intersegmental plane is essential in segmentectomy, and Indocyanine Green (ICG) assists in visualizing lung segments. Various factors, including patient-related, intraoperative, and technical issues, can influence boundary delineation. This study aims to assess the rate of unsuccessful intersegmental identification and identify the contributing factors. We analyzed cases of lung segmentectomy from April 2020 to March 2023, where intraoperative ICG was intravenously administered during robot-assisted or video-assisted thoracoscopic surgery. Cases where fluorescence extended beyond expected boundaries within 30 s were classified as the "unclear boundary group". This group was then compared to the "clear boundary group". The study encompassed 111 cases, 104 (94%) of which were classified under the "clear boundary group" and 7 (6%) under the "unclear boundary group". The "unclear boundary group" had a significantly lower DLCO (15.7 vs. 11.8, p = 0.03) and DLCO/VA (4.3 vs. 3.0, p = 0.01) compared to the "clear boundary group". All cases in the "unclear boundary group" underwent lower lobe segmentectomy. ICG administration effectively outlines pulmonary segments. Challenges in segment demarcation may occur in cases with low DLCO and DLCO/VA values, particularly during lower lobe segmentectomy.

Robot-assisted thoracoscopic surgery for mediastinal tumours in children: a single-centre retrospective study of 149 patients.

OBJECTIVES: The purpose of this retrospective study was to summarize our experience in performing robot-assisted thoracoscopic surgery (RATS) for mediastinal tumours in children to investigate its safety and feasibility. METHODS: This retrospective study involved 149 patients with mediastinal tumours who were hospitalized in the Department of Thoracic Surgery of Beijing Children's Hospital, Capital Medical University, and underwent RATS for tumour resection from March 2021 to November 2022. Information on patient age, weight, tumour size, surgical incision selection, operative time, intraoperative bleeding, intraoperative complications, length of hospital stay, rate of conversion to thoracotomy and follow-up conditions were summarized. RESULTS: All 149 surgeries were successfully completed with no cases of mortality. There were 77 male and 72 female patients, with a mean age of 5.9 years (range: 6 months-16 years, 8 months) and a mean weight of 23.6 kg (8.0-72.0 kg). The mean maximum tumour diameter was 5.5 cm (2.0-12.0 cm), the mean operative time was 106.7 min (25.0-260.0 min), the mean intraoperative bleeding volume was 11.3 ml (1.0-400.0 ml) and the mean hospital stay was 7.2 days (4.0-14.0 days). All patients recovered well with no cases of tumour recurrence or mortality during the postoperative follow-up period (3-23 months). CONCLUSIONS: RATS is safe and feasible to apply in children with mediastinal tumours who are >6 months of age and weigh more than 8 kg in terms of short-term outcomes, but longer-term follow-up is needed to fully evaluate the benefits. For cases that are associated with greater surgical difficulty and risk, a comprehensive surgical plan should be fully prepared in advance of surgery.

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

BACKGROUND: Both 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). METHODS: A 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. RESULTS: Compared 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). CONCLUSION: For 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.

Transthoracic robotic plication for diaphragmatic elevation.

Background: This study aims to evaluate the feasibility, safety, and efficacy of transthoracic robot-assisted surgery for diaphragmatic plication and to describe our surgical approach in detail. Methods: Between January 2014 and January 2020, a total of 13 patients (11 males, 2 females; median age: 55 years; range, 24 to 70 years) who underwent diaphragmatic plication with the robotic system were retrospectively analyzed. The changes in the Medical Research Council dyspnea scale, forced expiratory volume in 1 sec, body mass index, and quality of life scale scores of the patients before the operation and at the first year of follow-up were examined. Results: Twelve of the operations were performed on the left side. The median pre- and postoperative Medical Research Council dyspnea scores were 2 (range, 1 to 4) and 1 (range, 1 to 4), respectively, indicating a statistically significant improvement (p=0.008). A significant improvement was detected in the forced expiratory volume in 1 sec of the patients in the first year after surgery (p=0.036). In terms of quality of life parameters, only, in the physical health subscale, the scores were statistically significantly different in the pre- and postoperative first-year follow-up (p=0.002). Median time to chest tube removal was 1 (range 1-5, IQR=0,5) days. Median total length of hospital stay was 2 (range 2-18, IQR=3) days. Conclusion: Owing to its technical dexterity, the robot enables the plication to be performed easily and safely. Late improvement in respiratory functions is reflected in quality of life.

Short-term outcomes of robot-assisted versus video-assisted thoracoscopic surgery for non-small cell lung cancer patients with neoadjuvant immunochemotherapy: a single-center retrospective study.

Background: Neoadjuvant immunochemotherapy has been increasingly applied to treat non-small cell lung cancer (NSCLC). However, the comparison between robotic-assisted thoracoscopic surgery (RATS) and video-assisted thoracoscopic surgery (VATS) in the feasibility and oncological efficacy following neoadjuvant immunochemotherapy is scarce. This study aims to assess the superiorities of RATS over (VATS) concerning short-term outcomes in treating NSCLC patients with neoadjuvant immunochemotherapy. Methods: NSCLC patients receiving RATS or VATS lobectomy following neoadjuvant immunochemotherapy at Shanghai Chest Hospital from 2019 to 2022 were retrospectively identified. Baseline clinical characteristics, perioperative outcomes, and survival profiles were analyzed. Results: Forty-six NSCLC patients with neoadjuvant immunochemotherapy were included and divided into the RATS (n=15) and VATS (n=31) groups. The baseline clinical characteristics and induction-related adverse events were comparable between the two groups (all p>0.050). The 30-day mortality in the RATS and VATS groups were 0% and 3.23%, respectively (p=1.000). Patients undergoing RATS were associated with reduced surgical-related intensive unit care (ICU) stay than those receiving VATS (0.0 [0.0-0.0] vs. 0.0 [0.0-1.0] days, p=0.026). Moreover, RATS assessed more N1 LNs (6.27 ± 1.94 vs 4.90 ± 1.92, p=0.042) and LN stations (3.07 ± 1.03 vs 2.52 ± 0.57, p=0.038) compared with VATS. By comparison, no difference was found in surgical outcomes, pathological results, and postoperative complications between the RATS and VATS groups (all p>0.050). Finally, RATS and VATS achieved comparable one-year recurrence-free survival (82.96% vs. 85.23%, p=0.821) and the timing of central nervous system, LN, and bone recurrences (all p>0.050). Conclusion: RATS is safe and feasible for NSCLC patients with neoadjuvant immunochemotherapy, reducing surgical-related ICU stay, assessing increased N1 LNs and stations, and achieving similar survival profiles to VATS.
