RESUMO
Here we report a rare case of immunoglobulin G4 (IgG4)-related pleural disease diagnosed using a thoracoscopic pleural biopsy. A 66-year-old man was admitted to our hospital with right-dominant bilateral pleural effusions and gradually worsening dyspnoea. Chest radiographs revealed right-dominant pleural effusions, while chest computed tomography showed bilateral pleural effusions without parenchymal lesions. Although the bilateral pleural effusions were exudative with an increased number of lymphocytes, the definitive diagnosis was initially elusive. High IgG4 levels in the serum and pleural effusions were observed. A pathological evaluation of a right pleural biopsy specimen collected via video-assisted thoracoscopic surgery showed fibrosis-associated lymphoplasmacytic infiltration, 45-60 IgG4-positive plasma cells per high-power field, and an IgG4/immunoglobulin G ratio of 40%. Consequently, the patient was diagnosed with IgG4-related pleural disease. The bilateral pleural effusions improved after corticosteroid therapy.
RESUMO
INTRODUCTION: Minimally invasive lung resection has been associated with improved outcomes; however, institutional characteristics associated with utilization are unclear. We hypothesized that the presence of surgical robots at institutions would be associated with increased utilization of minimally invasive techniques . METHODS: Patients with cT1/2N0M0 non-small cell lung cancer who underwent lung lobectomy between 2010 and 2020 in the National Cancer Database were identified. Patients were categorized by operative approach as minimally invasive surgery (MIS) versus open. Institutions were categorized as "high utilizers" of MIS technique if their proportion of MIS lobectomies was >50%. Multivariate logistic regressions were used to determine factors associated with proportion of procedures performed minimally invasively. Further multivariate models were used to evaluate the association of proportion of MIS procedures with 90-d mortality, hospital length of stay, and hospital readmission. RESULTS: In multivariate analysis, passage of time by year (odds ratio [OR] 1.26; confidence interval [CI] 1.22-1.30) and presence of a robot at the facility (OR 3.48; CI 2.84-4.24) were associated with high MIS-utilizing facilities. High utilizers of MIS were associated with lower 90-d mortality (OR 0.89; CI 0.83-0.97) and hospital length of stay (coeff -0.88; CI -1.03 to -0.72). Hospital readmission was similar between high and low MIS-utilizing facilities (compared to low MIS-utilizing facilities: OR 1.06; CI 0.95-1.09). CONCLUSIONS: Passage of time and the presence of surgical robots were independently associated with increased utilization of MIS lobectomy. In addition to being associated with improved patient-level outcomes, robotic surgery is correlated with a higher proportion of procedures being performed minimally invasively.
RESUMO
INTRODUCTION: This study, conducted between December 2015 and March 2018 at a single university hospital, explored the feasibility and safety of opioid-free anesthesia combined with preoperative thoracic paravertebral block (ThPVB) for patients undergoing elective video-assisted thoracoscopic surgery (VATS). The aim was to assess the impact of this approach on postoperative pain levels and opioid consumption. MATERIAL AND METHODS: Sixty-four patients scheduled for elective VATS were randomly assigned to either the intervention group, receiving opioid-free anesthesia with ThPVB, or the control group, managed with standard general anesthesia. Postoperatively, both groups received oxycodone patient-controlled analgesia along with non-opioid analgesics. Pain intensity was measured using the Numeric Pain Rating Scale (NRS) and Prince Henry Hospital Pain Score (PHHPS). The total dose of postoperative oxycodone and the occurrence of opioid-related adverse events were recorded during the 24-hour follow-up period. RESULTS: Patients in the intervention group showed significantly lower pain levels at 20 and 24 hours post-procedure ( P = 0.015, P = 0.021, respectively) compared to the control group. Notably, oxycodone consumption at 24 hours was significantly higher in the control group ( p < 0.0001). No serious adverse events were observed during the study period. CONCLUSIONS: This study demonstrates the feasibility and safety of opioid-free anesthesia combined with ThPVB for elective VATS. The approach significantly reduces postoperative pain and the need for opioids, supporting its potential as an effective and balanced perioperative anesthetic strategy.

Introduction In September 2020, the Institute for Pulmonary Diseases of Vojvodina (IPBV) started a lung cancer screening program using low-dose computed tomography (LDCT). Video-assisted thoracic surgery (VATS) lobectomy is the most effective treatment for early-stage lung cancer. However, the frequency of postoperative complications in VATS anatomical lung resections among patients enrolled in the screening program has not been adequately studied. This study aims to compare the frequency of surgical complications and length of hospital stay between patients enrolled in the screening program and a control group. Methods Retrospective, observational, monocentric, non-randomized study was conducted at the IPBV in Sremska Kamenica. The study included patients with a confirmed diagnosis of lung cancer who underwent anatomic pulmonary resection with mediastinal lymphadenectomy for therapeutic purposes. The patients were divided into two groups: the first group consisted of 34 patients who participated in the lung carcinoma screening program, while the second control group consisted of 102 patients. Over the past three years, all patients identified with nodules suspicious of malignancy during the screening program were sequentially enrolled in the screening group. For the control group, patients were selected based on a matching process to ensure valid statistical comparisons with the screening group. They were matched in a 3:1 ratio with patients from the screening group based on criteria including gender, disease stage, pathohistological type of cancer, tumor, node, and metastasis (TNM) stage of the disease, and degree of surgical resection. Patients were monitored for demographic parameters, smoking status, presence of comorbidities and prior oncological diseases, pulmonary function parameters, level of pre-operational risk, the number of lymph nodes removed by biopsies, spread through alveolar spaces (STAS), and the occurrence of complications after surgery (infection, bleeding, air leak, presence of adhesions), re-drainage, and length of hospital stay. Results The patients in the screening group had a higher incidence of infections, bleeding, prolonged air leak, and required re-drainage after surgery compared to the control group. Patients from the screening program with a high operative risk, prolonged air leak, and pleural adhesions had a statistically significant higher hospital stay longer than the control group. Conclusions This research emphasizes the importance of screening programs for detecting lung cancer in the early stages. However, it also highlights the need for further research to reduce surgical complications and improve therapeutic interventions for patients in the screening program.
RESUMO
BACKGROUND: Nowadays, video-assisted thoracic surgery (VATS) lobectomy represents the treatment of choice for early-stage lung cancer. Over the years, different methods for VATS training have evolved. The aim of this study is to present an innovative beating-heart filled-vessel cadaveric model to simulate VATS lobectomies. METHODS: Via selective cannulation of the cadaver heart, the pulmonary vessels were filled with a gel to improve their haptic feedback. An endotracheal tube with a balloon on its tip then allowed movement of the heart chambers, transmitting a minimum of flow to the pulmonary vessels. A simulated OR was created, using all instrumentation normally available during surgery on living patients, with trainees constantly mentored by experienced surgeons. At the end of each simulation, the participants were asked 5 questions on a scale of 1 to 10 to evaluate the effectiveness of the training method ("1" being ineffective and "10" being highly effective). RESULTS: Eight models were set up, each with a median time of 108 min and a cost of 1500. Overall, 50 surgeons were involved, of which 39 (78%) were consultants and 11 (22%) were residents (PGY 3-5). The median scores for the 5 questions were 8.5 (Q1; IQR1-3 8-9), 8 (Q2; IQR1-3 7-9), 9 (Q3; IQR1-3 8-10), 9 (Q4; IQR1-3 8-10), and 9 (Q5; IQR1-3 8-10). Overall, the model was most appreciated by young trainees even though positive responses were also provided by senior surgeons. CONCLUSIONS: We introduce a new beating-heart filled-vessel cadaveric model to simulate VATS lobectomies. From this initial experience, the model is cost effective, smooth to develop, and realistic for VATS simulation.
RESUMO
PURPOSE: Traditional anesthesia for video-assisted thoracoscopy (VATS) such as double-lumen tracheal intubation (DLT) and one-lung ventilation (OLV), may lead to post-operative pulmonary complications (PPCs). Non-intubation VATS (NIVATS) is an anesthetic technique that avoided DLT and OLV, maybe avoiding the PPCs. So we hypothesized that NIVATS would non-inferiority to intubation VATS (IVATS) in the risk of developing PPCs and some safety indicators. METHODS: This study is a randomised, controlled, double-blind, non-inferiority trial, 120 patients were randomly assigned to the NIVATS group and IVATS group according to 1:1. The primary outcome was the incidence of PPCs with a pre-defined non-inferiority margin of 10%. The second outcome was the safety indicators, including the incidence of cough/body movement, hypoxemia, malignant arrhythmia, regurgitation and aspiration, and transferring to endobronchial intubation intraoperatively (The malignant arrhythmia was defined as an arrhythmia that caused hemodynamic disturbances in a short period of time, resulting in persistent hypotension or even cardiac arrest in the patient). RESULTS: There was no significant difference in demographic indicators such as gender and age between the two groups. The incidence of PPCs in the NIVATS group was non-inferior to that in the IVATS group (1.67% vs. 3.33%, absolute difference: - 1.67%; 95%CI - 7.25 to 3.91). In additionan, no significant differences were found between the two groups for the incidence of cough/body movement (10.00% vs. 11.67%, p = 0.77), the incidence of hypoxemia (25% vs. 18.33%, p = 0.38), the incidence of malignant arrhythmia (1.67% vs. 6.67%, p = 0.36), the incidence of regurgitation and aspiration (0% vs. 0%, p > 0.999) and the incidence of transferring to endobronchial intubation intraoperatively (0% vs. 0%, p > 0.999). CONCLUSION: We conclude that when using the non-intubation anesthesia for VATS, the incidence of PPCs was not inferior to intubation anesthesia. Furthermore, NIVATS had little effect on perioperative safety.
RESUMO
BACKGROUND: Robot-assisted thoracic surgery (RATS) is gaining popularity in lung resection surgeries; however, its quality outcome measures require further evaluation. This study compared the short-term perioperative outcomes of lung resection surgeries performed using RATS and video-assisted thoracic surgery (VATS) at a tertiary hospital in the UK. METHODS: We performed a retrospective comparative analysis of 496 patients who underwent lung resection surgery at Castle Hill Hospital in the UK between January 2021 and April 2024. In the pre-matched cohort, 162 patients underwent RATS compared to 334 who underwent VATS. Using propensity matching based on the patient's forced expiratory volume in one second (FEV1) percentage of predicted age and body mass index (BMI), we included 324 patients in the analysis. Of these, 162 underwent RATS, and 162 underwent VATS, demonstrating satisfactory performance indicators. RESULTS: The results from our analysis depicted that RATS had a significantly lower rate of prolonged air leak (≥7 minutes) than VATS (5.5% versus 7.1%, mean difference -1.32, 95% CI: -0.89-3.08, p = 0.034). RATS patients also had shorter duration of hospital stay (3.8 ± 4.1 days versus 4.7 ± 4.8, mean difference -0.901, 95% CI: -1.886-0.084; p = 0.073) and had more mediastinal lymph node dissections (39.5% versus 35.2%) than VATS. However, the proportion of patients who were upstaged after histopathological analysis of the resected lymph nodes was not different between the two groups. Furthermore, the groups had no significant differences regarding the infection rate, intermittent positive pressure ventilation (IPPV) use, and theatre return. CONCLUSION: Robotic and video-assisted technologies produced equivalent results for the majority of the short-term outcomes evaluated. Additional research is necessary to confirm RATS's efficacy and determine its potential advantages over VATS for lung resection surgeries.
RESUMO
Background: Reported advantages to robotic thoracic surgery include shorter length of stay (LOS), improved lymphadenectomy, and decreased complications. It is uncertain if these benefits occur when introducing robotics into a well-established video-assisted thoracoscopy (VATS) practice. We compared the two approaches to investigate these advantages. Materials and methods: IRB approval was obtained for this project. Patients who underwent segmentectomy or lobectomy from May 2016-December 2018 were propensity-matched 2: 1 (VATS: robotic) and compared using weighted logistic regression with age, gender, Charlson Comorbidity Index, surgery type, stage, Exparel, and epidural as covariates. Complication rates, operation times, number of sampled lymph nodes, pain level, disposition, and LOS were compared using Wilcoxon rank-sum and with Rao-Scott Chi-squared tests. Results: 213 patients (142 VATS and 71 robot) were matched. Duration of robotic cases was longer than VATS (median 186 min (IQR 78) vs. 164 min (IQR 78.75); p < 0.001). Significantly more lymph nodes (median 11 (IQR 7.50) vs. 8 (IQR 7.00); p = 0.004) and stations were sampled (median 4 (IQR 2.00) vs. 3 (IQR 1.00); p < 0.001) with the robot. Interestingly, robotic resections had higher 72-hour pain scores (median 3 (IQR 3.25) vs. 2 (IQR 3.50); p = 0.04) and 48-hour opioid usage (median 37.50 morphine milligram equivalents (MME) (IQR 45.50) vs. 22.50 MME (IQR 37.50); p = 0.01). Morbidity, LOS, and disposition were similar (all p > 0.05). Conclusions: The robotic approach facilitates better lymph node sampling, even in an established VATS practice.
RESUMO
Background: Video-assisted thoracic surgery (VATS) has become the gold-standard approach for lung resections. Given the impossibility of digital palpation, we witnessed the progressive development of peri-centimetric and deeply located pulmonary nodule alternative detection techniques. Intra-operative lung ultrasound is an increasingly effective diagnostic method, although only a few small studies have evaluated its accuracy. This study analyzed the effectiveness and sensitivity of uniportal VATS with intra-operative lung ultrasound (ILU), in comparison to multiportal VATS, for visualizing solitary and deep-sited pulmonary nodules. Methods: Patient data from October 2021 to October 2023, from a single center, were retrospectively gathered and analyzed. In total, 31 patients who received ILU-aided uniportal VATS (Group A) were matched for localization time, operative time, sensitivity, and post-operative complications, with 33 undergoing nodule detection with conventional techniques, such as manual or instrumental palpation, in multiportal VATS (Group B). Surgeries were carried out by the same team and ILU was performed by a certified operator. Results: Group A presented a significantly shorter time for nodule detection [median (IQR): 9 (8-10) vs. 14 (12.5-15) min; p < 0.001] and operative time [median (IQR): 33 (29-38) vs. 43 (39-47) min; p < 0.001]. All nodules were correctly localized and resected in Group A (sensitivity 100%), while three were missed in Group B (sensitivity 90.9%). Two patients in Group B presented with a prolonged air leak that was conservatively managed, compared to none in Group A, resulting in a post-operative morbidity rate of 6.1% vs. 0% (p = 0.16). Conclusions: ILU-aided uniportal VATS was faster and more effective than conventional techniques in multiportal VATS for nodule detection.
RESUMO
Background: Preoperative three-dimensional (3D) lung reconstructions can reduce intraoperative blood loss, conversion rate, and operation duration. These 3D reconstructions are predominantly provided by commercial expensive products, hence we aimed to assess the usability and performance of preoperative 3D lung reconstructions created with open-source software. Methods: Patients were invited to participate in this prospective pilot study if they were planned for uniportal video-assisted thoracoscopic surgery (VATS) lobectomy or segmentectomy between January and February 2023. Participants were excluded if a two-dimensional (2D) late-arterial-phase computed tomography (CT) scan contained motion artifacts, another surgical procedure was performed, or the surgery was canceled. After informed consent was obtained, 3D lung reconstructions were constructed using open-source 3D Slicer software. The system usability score (SUS) questionnaire assessed the usability of these reconstructions, whilst performance was evaluated based on anatomical validity compared to prior 2D CT assessment as well as operative findings. Descriptive statistics were reported. Results: Thirteen patients were included, of whom one underwent a segmentectomy. Eighty-three percent of the 3D lung reconstructions scored above average (SUS >68). Compared to 2D CT scans, 38% of lung nodule segmental locations were detected more accurately through 3D lung reconstructions. Furthermore, 3D lung reconstructions revealed anatomical variations in 62%, which were not recognized on 2D CT scans, and provided surgeons with insights that would change the procedure and/or transection planes in 62%. One 3D lung reconstruction failed to demonstrate an intraoperative recognized segmental pulmonary artery (A6) branch. Conclusions: Three-dimensional lung reconstructions created with open-source software were usable and effective for uniportal VATS anatomical resections. Trial Registration: ClinicalTrials.gov/NCT06132607.
RESUMO
BACKGROUND: The advantages of video-assisted thoracic surgery (VATS) are well-recognized in several studies. However, in the cases of advanced lung cancer after neoadjuvant chemotherapy (nCT), the role of VATS is still questionable, with concerns about safety, technical feasibility, and oncological completeness. The aim of this study was to assess the impact of nCT on patients who had undergone uniportal VATS (U-VATS) anatomic lung resections for lung cancer, by comparing the short-term outcomes of patients after nCT with case-matched counterparts (treated by surgery alone). METHODS: We performed a retrospective, comparative study enrolling 927 patients (nCT: 60; non-nCT:867) who underwent U-VATS anatomic lung resections from 2014 to 2020 in two centers. Data were collected in a shared database with standardized variables' definition. Propensity score matching using 15 baseline preoperative patients' characteristics was performed in order to minimize selection-confounding factors between the two groups, which then were directly compared in terms of perioperative outcomes. RESULTS: After propensity score matching, two groups of 60 patients had been defined. The nCT-group had a higher conversion rate compared to the control group (13.3% vs. 0%, p = 0.003) without an increase in operation time or cardiopulmonary complications. In addition, no differences between the two groups were recorded in terms of prolonged air leaks, length of stay, and readmission. CONCLUSIONS: U-VATS after nCT is a feasible approach, showing a similar rate of cardiopulmonary complications and length of stay when compared with the control group. However, it remains a challenging surgery due to its great technical complexity as well as the clinical status of the patients.
RESUMO
We present this clinical case as a demonstration of difficulties in differential diagnosis of pulmonary coccidioidomycosis. Differential diagnostics of peripheral pulmonary lesion performed using bronchoscopy with BAL and TBCB and video-assisted thoracic surgery (VATS) biopsy. Diagnostic specimens were tested using microbiological (luminescent microscopy, culture for M. tuberculosis (BACTEC MGIT960 and Lowenstein-Jensen Medium), RT-PCR, cytological and morphological (hematoxylin-eosin, Ziehl-Neelsen, PAS, Grocott methenamine silver (GMS) stainings) examinations. A diagnosis was verified correctly In Russia the country is not endemic for coccidioidomycosis and patient was treated accordingly. Diagnostics of peripheral pulmonary lesions requires of multidisciplinary approaches. Morphological examination, based on detection of only granulomatous inflammation in lung biopsy cannot be used for finally DS and requires microbiological confirmation for TB or other infections, and dynamic monitoring of the patient with concordance their anamnesis vitae and morbi.

Background: Despite widespread application of minimally invasive video-assisted thoracic surgery (VATS), postoperative pain following this procedure is still a constant clinical challenge. Serratus anterior plane (SAP) block is one of the regional analgesic techniques with promising outcomes. However, due to the limited duration of action, optimal analgesia is often not achieved with a single injection. We tested whether in patients who have been subjected to routine SAP block under preoperative anesthesia, the addition of a second SAP block 24 hours after surgery, improves quality of recovery, lowers postoperative opioid consumption, and reduces the prevalence of chronic pain. Methods: The present study is a single institutional, prospective, randomized, triple-blinded, placebo-controlled study. Ninety patients undergoing VATS from January 2022 to April 2022 were randomized at 1:1 ratio to receive ultrasound-guided second SAP block with 15 mL 0.375% ropivacaine (SAP block group) or 15 mL normal saline (control group) 24 hours after both groups received routine SAP block with 15 mL 0.375% ropivacaine. The primary outcome was quality of patient recovery, measured using 40-item quality of recovery questionnaire (QoR-40) at postoperative day 2 (POD 2). Secondary outcomes included: postoperative pain scores at rest, postoperative opioid consumptions, number of times that patient controlled analgesia (PCA) pump button was pressed, perioperative complications and adverse effects, prevalence of chronic pain at 2nd and 3rd month postoperatively, and length of hospital stay (LOS). Results: A total of 83 patients completed the study: 43 patients in SAP block group and 40 patients in the control group. The global QoR-40 scores on POD 2 and POD 3 were significantly higher among SAP block group patients (180.07±11.34, 182.09±8.20) compared with the control group (172.18±6.15, 177.50±6.94) (P=0.01, P=0.008) respectively. Postoperative pain scores, opioid consumptions and incidence of postoperative nausea and vomiting were significantly lower among patients in SAP block group versus control group. There were no statistically significant differences in perioperative complications and LOS between the two groups. The prevalence of chronic pain at the 2nd and 3rd month postoperatively for patients in SAP block group and control group was 16.3%, 14%, and 32.5%, 27.5% respectively. Conclusions: In patients undergoing VATS, application of ultrasound-guided second SAP block 24 hours after surgery improved postoperative quality of life, reduced opioid consumption and related side effects, and lowered the prevalence of chronic pain.
RESUMO
Background: Low-dose computed tomography (CT) has been increasingly utilized for lung cancer screening. Localization of solitary pulmonary nodules (SPN) is crucial for resection. Two-stage localization method involves dye injection by radiologists prior to the operation. The significant interval between localization and resection is associated with a higher risk of marker failure, psychological distress and procedural complications. Single-stage localization and resection procedure under general anesthesia poses unique challenges. The aim of the study is to compare the safety, efficacy and patient satisfaction between the two methods. Methods: This is a retrospective study comparing outcomes between two-stage and single-stage pre-operative localization of SPN. The primary study outcome was total operating time. Secondary outcomes included successful lesion localization, complication rate, 30-day readmission, mortality, patient satisfaction, and pain level. Results: A total of 26 and 56 patients were included for the single and two-stage group respectively. Total operative time was significantly longer in the single-stage arm (mean: 188 min) than that of the two-stage arm (mean: 172 min, P<0.001) due to the additional time needed for intra-operative localization. Mean satisfaction score was significantly higher in the single-stage group than that of the two-stage group (92 vs. 52.69, P=0.004). Pain level assessed by numerical rating scales was better in the single-stage arm compared to the two-stage arm (mean: 8.8 vs. 4.85, P=0.007). Conclusions: Single-stage localization and resection resulted in a minor increase in total operative time, higher patient satisfaction and less pain with comparable safety and efficacy to conventional two-stage approach.
RESUMO
Objectives: Surgery 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. Methods: Groups 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. Results: From 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. Conclusions: There 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.
RESUMO
Twenty years have passed since uniportal video-assisted thoracoscopic surgery (VATS) was first reported. Several reports have already proven the minimal invasiveness of uniportal VATS. In addition, two large clinical trials recently demonstrated the benefits of segmentectomy for small peripheral early-stage non-small cell lung cancer. Uniportal VATS segmentectomy is considered the most beneficial minimally invasive surgery for patients with early-stage lung cancer. However, a high level of skill and experience are required to achieve this goal. Only a few reports have discussed specific techniques, particularly for complex segmentectomies. In this Special Issue, we reviewed previous reports on uniportal VATS segmentectomy regarding the indications, instrument selection, marking of the tumor location, methods of intersegmental plane identification, and lymph node dissection, including our own techniques with video content.
RESUMO
Background: The incidence and risk factors for recurrent primary spontaneous pneumothorax (PSP) after video-assisted thoracoscopic surgery (VATS) remain controversial. A systematic review and meta-analysis were conducted to determine the incidence and risk factors for recurrence of PSP after VATS. Methods: A systematic search of PubMed, Web of Science, Embase, and Cochrane Library databases was conducted to identify studies that reported the rate and risk factors for recurrence of PSP after VATS published up to December 2023. The pooled recurrence rate and odds ratio (OR) with 95% confidence interval (CI) were calculated using a random-effects model. In addition, risk factors were similarly included in the meta-analysis, and sources of heterogeneity were explored using meta-regression analysis. Results: A total of 72 studies involving 23,531 patients were included in the meta-analysis of recurrence. The pooled recurrence rate of PSP after VATS was 10% (95% CI: 8-12%). Male sex (OR: 0.61; 95% CI: 0.41-0.92; P=0.02), younger age [mean difference (MD): -2.01; 95% CI: -2.57 to -1.45; P<0.001), lower weight (MD: -1.57; 95% CI: -3.03 to -0.11; P=0.04), lower body mass index (BMI) (MD: -0.73; 95% CI: -1.08 to 0.37; P<0.001), and history of contralateral pneumothorax (OR: 2.46; 95% CI: 1.56-3.87; P<0.001) were associated with recurrent PSP, whereas height, smoking history, affected side, stapling line reinforcement, and pleurodesis were not associated with recurrent PSP after VATS. Conclusions: The recurrence rate of PSP after VATS remains high. Healthcare professionals should focus on factors, including sex, age, weight, BMI, and history of contralateral pneumothorax, that may influence recurrence.
