Atrial fibrillation remains the most frequent sustained arrhythmia, particularly in the elderly population, and is associated with increased risks of stroke, heart failure, and reduced quality of life. While catheter ablation is widely used for rhythm control, its efficacy is limited in persistent and long-standing atrial fibrillation. Over the past two decades, minimally invasive surgical strategies have emerged as effective alternatives, aiming to replicate the success of the Cox-Maze procedure while reducing surgical trauma. This overview critically summarizes the current minimally invasive techniques available for atrial fibrillation treatment, including mini-thoracotomy ablation, thoracoscopic ablation, and hybrid procedures such as the convergent approach. These methods offer the potential for durable sinus rhythm restoration by enabling direct visualization, transmural lesion creation, and left atrial appendage exclusion, with lower perioperative morbidity compared to traditional open surgery. The choice of energy source plays a key role in lesion efficacy and safety. Particular attention is given to the technical steps of each procedure, patient selection criteria, and the role of left atrial appendage closure in stroke prevention. Hybrid strategies, which combine epicardial surgical ablation with endocardial catheter-based procedures, have shown encouraging outcomes in patients with refractory or long-standing atrial fibrillation. Despite the steep learning curve, minimally invasive techniques provide significant benefits in terms of recovery time, reduced hospital stay, and fewer complications. As evidence continues to evolve, these approaches represent a key advancement in the surgical management of atrial fibrillation, deserving integration into contemporary treatment algorithms and multidisciplinary heart team planning.

Background/Objectives: The extensive use of computed tomography (CT) has led to a significant increase in the detection of small and non-palpable pulmonary nodules, necessitating the use of invasive methods for definitive diagnosis. Video-assisted thoracoscopic surgery (VATS) has become the preferred procedure for nodule resections; however, intraoperative localization remains challenging, especially for deep or subsolid lesions. This study explores whether SPECT/CT improves the technical and clinical outcomes of radio-guided occult lesion localization (ROLL) before uniportal video-assisted thoracoscopic surgery (u-VATS). Methods: This is a retrospective study involving consecutive patients referred for the resection of pulmonary nodules who underwent CT-guided ROLL followed by u-VATS between September 2017 and December 2024. From January 2023, SPECT/CT was systematically added after planar imaging. The cohort was divided into a planar group and a planar + SPECT/CT group. The inclusion criteria involved nodules sized ≤ 2 cm, with ground glass or solid characteristics, located at a depth of <6 cm from the pleural surface. ^99mTc-MAA injected activity, timing, the classification of planar and SPECT/CT image findings (focal uptake, multisite with focal uptake, multisite without focal uptake), spillage, and post-procedure complications were evaluated. Statistical analysis was performed, with continuous data expressed as the median and categorical data as the number. Comparisons were made using chi-square tests for categorical variables and the Mann–Whitney U test for procedural duration. Cohen’s kappa coefficient was calculated to assess agreement between imaging modalities. Results: In total, 125 patients were selected for CT-guided radiotracer injection followed by uniportal-VATS. The planar group and planar + SPECT/CT group comprised 60 and 65 patients, respectively. Focal uptake was detected in 68 (54%), multisite with focal uptake in 46 (36.8%), and multisite without focal uptake in 11 patients (8.8%). In comparative analyses between planar and SPECT/CT imaging in 65 patients, 91% exhibited focal uptake, revealing significant differences in classification for 40% of the patients. SPECT/CT corrected the classification of 23 patients initially categorized as multisite with focal uptake to focal uptake, improving localization accuracy. The mean procedure duration was 39 min with SPECT/CT. Pneumothorax was more frequently detected with SPECT/CT (43% vs. 1.6%). The intraoperative localization success rate was 96%. Conclusions: SPECT/CT imaging in the ROLL procedure for detecting pulmonary nodules before u-VATs demonstrates a significant advantage in reclassifying radiotracer positioning compared to planar imaging. Considering its limited impact on surgical success rates and additional procedural time, SPECT/CT should be reserved for technically challenging cases. Larger sample sizes, multicentric and prospective randomized studies, and formal cost–utility analyses are warranted. Full article

Background: Minimally invasive surgery (MIS) is increasingly adopted in pediatric surgical practice, yet it demands specific technical skills that require structured training. Simulation-based education offers a safe and effective environment for skill acquisition, especially in complex procedures such as thoracoscopic repair of esophageal atresia with tracheoesophageal fistula (EA-TEF). Objective: This study aimed to evaluate the effectiveness of a 3D-printed simulator for training pediatric surgeons in thoracoscopic EA-TEF repair, assessing improvements in operative time and technical performance. Methods: A high-fidelity, 3D-printed simulator replicating neonatal thoracic anatomy was developed. Six pediatric surgeons at different training levels performed eight simulation sessions, including fistula ligation and esophageal anastomosis. Operative time and technical skill were assessed using the Stanford Microsurgery and Resident Training (SMaRT) Scale. Results: All participants showed significant improvements. The average operative time decreased from 115.6 ± 3.51 to 90 ± 6.55 min for junior trainees and from 100.5 ± 3.55 to 77.5 ± 4.94 min for senior trainees. The mean SMaRT score increased from 23.8 ± 3.18 to 38.3 ± 3.93. These results demonstrate a clear learning curve and enhanced technical performance after repeated sessions. Conclusions: Such 3D-printed simulation models represent an effective tool for pediatric MIS training. Even within a short time frame, repeated practice significantly improves surgical proficiency, supporting their integration into pediatric surgical curricula as an ethical, safe, and efficient educational strategy.

Objectives: Residual postoperative pleural space (RPPS) is a common event after pulmonary lobectomy. Uniportal video-assisted thoracoscopic surgery (VATS) lobectomy has been associated with a higher incidence of RPPS. This study aims to evaluate the incidence, the predictors, and potential clinical implications of RPPS following Uniportal VATS lobectomy. Methods: Patients who underwent Uniportal VATS lobectomy, without any previous neoadjuvant treatment, from June 2016 to March 2020, were retrospectively analyzed. RPPS was assessed using the last chest X-Ray prior to discharge and measured by Collins method (%). Results: Among 492 patients who underwent Uniportal VATS lobectomy, 325 (66.1%) developed RPPS. The mean RPPS volume measured by the Collins method was 15.46 ± 8.59% (vs. Collins = 4.2% in no-PRPS). An RPPS > 10.5% of Collins was significantly associated with a higher risk of postoperative air leak (AUC: 0.69, sensitivity: 69%, specificity: 54%, p < 0.001). Multivariable analysis identified the following predictors of RPPS > 10.5%: right-sided surgery (p < 0.001), upper lobectomy (p = 0.01), and prolonged air leak (p = 0.003). Patients with RPPS had a higher risk of only radiologically visible postoperative subcutaneous emphysema on the final chest X-ray (p = 0.041) and were more frequently discharged with a chest tube connected to a Heimlich valve (p < 0.001). Within 90 days post-discharge, 24 (4.9%) patients were readmitted due to increased RPPS (1.4%, requiring drainage in 5 cases [1%]), progression of subcutaneous emphysema (1.6%), and pleural effusion (1.8%, requiring drainage in 6 cases [1.2%]). However, RPPS was not associated with an increased overall risk of postoperative complications (p = 0.31) or 90-day readmission (p = 0.43). Conclusions: RPPS is a common occurrence following Uniportal VATS lobectomy but is not associated with clinically significant complications. The current study findings identified BMI, active smoking, right-sided surgery, and prolonged air leak as significant predictors of RPPS. Full article

Objectives: Pericardial effusion is the accumulation of excess fluid in the pericardial sac. The etiology is multi-factorial and different techniques are used for management, including subxiphoid approaches, anterior and lateral thoracotomies, video-assisted thoracic surgery (VATS), and percutaneous pericardiocentesis. We evaluate the surgical management strategies for pericardial effusion and their outcomes in this systematic review. Methods: A systematic literature review was performed to identify studies on the surgical management of pericardial effusion from inception to February 2024 using PubMed, Cochrane, and Scopus. Articles were independently assessed by two reviewers, with discrepancies resolved by the senior author. Articles were considered for inclusion if they described different pericardial effusion surgical management techniques. Baseline patient characteristics and procedural and outcome variables were extracted. Results: A total of 27 studies comprising 2773 patients were evaluated. The median age was 56.2 years (interquartile range 47–62.2). The most common etiologies of pericardial effusion were malignancy (31.0%), post-cardiac surgery (18.7%), and idiopathic (15.4%). Other causes included uremia (9.6%), infection (9.6%), and autoimmune disease (4.2%). The subxiphoid pericardial window was the most common approach (82.6%), followed by anterior and lateral thoracotomy (12.0%), and median sternotomy (0.6%). At median follow-up of 24 months, the most frequent post-procedural complications were recurrence of effusion (10.5%), arrhythmias (2.7%), and pneumonia (0.7%). Conclusions: Subxiphoid pericardial window is the most common approach for draining pericardial effusions. Prognosis depends on both the underlying etiology and the chosen drainage strategy. Treatment should be tailored to individual patients, considering patient comorbidities and the specific etiology. Full article

Background: Lung cancer represents a significant health concern, particularly among the elderly population. With global life expectancy increasing, the number of very elderly patients is rising. Robotic-assisted thoracic surgery (RATS) offers potential advantages over both traditional and video-assisted thoracoscopic surgery (VATS). This study aims to evaluate the feasibility and safety of RATS in very elderly patients (VEP) diagnosed with lung cancer. Methods: This retrospective study included patients who underwent major lung resections using RATS between 2015 and 2022 at two specialized centers. Patients were divided into very elderly patients (VEP, ≥80 years) and non-elderly patients (NEP, <80 years). Demographic, clinical, and surgical data were analyzed. Propensity score matching (PSM) at a 1:3 ratio was performed using clinically relevant variables that were significantly different at baseline to balance the two groups. Results: This study included 340 patients: 28 VEP and 312 NEP. Before PSM, VEP had higher ASA scores, more advanced disease stages, and increased comorbidities. Despite these differences, postoperative outcomes were comparable. Complications occurred in 42.9% of VEP and 29.8% of NEP (p = 0.16), but grade III complications were observed in 14.3% of VEP and 6.4% of NEP (p = 0.12), and grade IV complications were observed in 0% of VEP and 0.9% of NEP (p = not estimable). The mean hospital stay was 4 days in both groups (p = 0.99). Even after PSM (26 VEP vs. 71 NEP), complications, hospital stay, and 90-day mortality (3.9% in VEP, 0% in NEP) were similar. Multivariable analysis identified reduced FEV1 as a predictor of complications, while pathological stage I and lobectomy were associated with a decreased risk of complications, both before and after PSM. Conclusions: RATS is a safe and feasible option for selected very elderly patients with lung cancer, yielding outcomes comparable to younger patients. Full article

Background: The positive effects of oral nutritional supplements (ONS) on postoperative outcomes have been well recognized in several previous studies. However, to date, little data has been available with respect to determining the best immune modulating supplement to use and what its impact might be in thoracic surgery. The aim of this study was to evaluate the role of preoperative immune-nutritional supplement intake as predictor of postoperative cardiopulmonary complications (CPCs) in patients undergoing uniportal video-assisted thoracoscopic (uVATS) lung resection. Methods: This is a retrospective, observational study enrolling consecutive patients who underwent uVATS lung resections for cancer from January 2022 to December 2024 in the context of the Enhanced Pathway of Care (EPC) Program. All patients were evaluated by a nutritionist and dietetics team during the preoperative phase. The nutritional protocol consisted of 250 mL ONS rich in arginine, omega-3-fatty acids, and nucleotides to be taken twice a day for 5–7 days before surgery. Results: Four hundred ninety-one patients were enrolled: 277 patients underwent anatomic lung resection and 214 underwent wedge resection (WR). Utilizing the univariate analysis, we found that in patients undergoing anatomic lung resection, not-ONS-intake, high Body Mass Index (BMI), and arrythmia were correlated with a higher CPCs rate compared to the patients without nutritional supplementation (7.2% ONS vs. 15% not-ONS, p = 0.04; BMI 28.4 kg/m² vs. BMI 26.4 kg/m², p = 0.03; 31.2% arrythmia vs. 9.4% no-arrythmia, p < 0.01). These correlations, except for BMI, were confirmed after stepwise logistic regression. Alternately, in patients undergoing WR, hypertension and low-FEV1% were associated with a higher CPCs rate (5.1% hypertension vs. 0.4% no-hypertension, p = 0.02; FEV1% 79.7% vs. 95%, p = 0.01). Conclusions: Our results demonstrated that preoperative ONS after uVATS anatomic lung resection, in the context of an EPC program, influences the postoperative period, reducing the CPCs rate.

Robot-assisted surgery has proven highly effective in the curative treatment of various gastrointestinal cancers. The advantages of robot-assisted surgery, including precision, enhanced operability, and magnified 3D visualization, allow surgeons to perform delicate procedures that would be challenging with conventional laparotomy or laparoscopy. These benefits make robot-assisted surgery a viable modality for treating various malignant tumors and an essential tool in curative surgery for solid cancers. Laparoscopic gastrectomy is currently the standard treatment for early gastric cancer, with numerous clinical trials assessing the efficacy of robot-assisted surgery. Although thoracoscopic esophagectomy has demonstrated advantages over open surgery in radical esophageal cancer treatment, ongoing studies are evaluating the noninferiority and potential benefits of robotic surgery. Robot-assisted surgery is also being explored for conversion surgery in cases where radical resection becomes feasible after multidisciplinary treatment and in polysurgery cases involving multiple prior laparotomies. However, establishing robust evidence for its efficacy in radical surgery for conversion and polysurgery cases remains a challenge. This narrative review discusses the advantages and limitations of robot-assisted surgery in such complex cases based on an analysis of the literature. Additionally, it examines the prospects of robotic-assisted surgery in polysurgery, metachronous remnant gastric cancer, and conversion surgery. Full article

Background: Esophageal atresia (EA) type A, characterized by the absence of a tracheoesophageal fistula and typically presenting with a long esophageal gap, usually requires staged repair. Methods: We report a rare case of a newborn with type A EA in which both the proximal and distal esophageal pouches were unexpectedly close and located in the cervical region. This anatomical variant allowed for a successful primary anastomosis through a cervical approach. Results: Initial imaging was misleading, and the true anatomy was clarified only through thoracoscopic exploration, underscoring the importance of intraoperative flexibility. Conclusions: To our knowledge, this is the first report of such a presentation in type A EA, with significant implications for diagnosis and surgical strategy. Full article

Background and Aims: Esophageal atresia (EA) and tracheoesophageal fistula (TEF) are rare but serious congenital anomalies requiring early surgical intervention. Over the past two decades, minimally invasive surgical (MIS) approaches—particularly thoracoscopic repair—have gained traction, aiming to reduce postoperative morbidity while maintaining surgical efficacy. Objective: This narrative review provides a comprehensive overview of the evolution and current status of MIS techniques for EA/TEF, assessing their clinical outcomes, technical challenges, and implications for patient care. Methods: A structured literature search was conducted to identify clinical studies, reviews, and reports on thoracoscopic, robotic-assisted, and endoscopic approaches to EA/TEF. Emerging adjuncts, including tissue engineering, botulinum toxin use, and magnet-assisted anastomosis, were also reviewed. Results: Thoracoscopic repair has demonstrated comparable anastomotic success rates to open surgery (approximately 85–95%) with significantly reduced rates of musculoskeletal complications, such as scoliosis and chest wall deformities (reported in less than 10% of cases, compared to up to 40% in open approaches). Robotic-assisted and endoscopic-assisted techniques have enabled improved visualization and precision in anatomically challenging cases, although their use remains limited to high-resource centers with specialized expertise. Common postoperative complications include anastomotic stricture (30–50%), gastroesophageal reflux disease (35–70%), and respiratory morbidity, necessitating long-term multidisciplinary follow-up. Recent innovations in simulation-based training and bioengineered adjuncts have facilitated safer MIS adoption in neonates. Conclusions: Minimally invasive techniques have improved the surgical management of EA/TEF, though challenges remain regarding technical complexity, training, and resource availability. Continued innovation and collaborative research are essential for advancing care and ensuring optimal outcomes for affected infants. Full article

Background and Objectives: The needle path is crucial for preoperative localization of deep thoracic pulmonary nodules using CT-guided patent blue dye (PBD) injection. This study aimed to evaluate the efficacy and safety of four categorized needle approach paths tailored to the anatomical location of the nodules. Materials and Methods: We retrospectively evaluated data from 50 consecutive patients (50 deep pulmonary nodules), who underwent CT-guided localization with PBD injection, between November 2015 and May 2023 at our hospital. The nodules could be divided into four categories: (1) perifissural nodules, (2) paravertebral nodules, (3) paramediastinal nodules, and (4) deep parenchymal nodules, according to their location relative to the thoracic organs and the visceral pleura. Needle approach methods and needle pathway lengths were recorded. Clinical and radiological features, technical information, pathological results, and procedure-related complications were analyzed. Results: All 50 dyes were successfully identified by thoracoscopy and then resected without major complication. The mean nodule diameter and the nodular depth were 10.3 (range, 4.7–21.0) mm and 16.1 (range, 0.1–52.2) mm. The needle pathway length was 7.7 (range, 4.5–11.7) cm. The mean procedure time was 16 (range, 8–26) minutes. Asymptomatic pneumothorax developed in twenty-four patients (48.0%), and focal parenchymal hemorrhage occurred in four patients (8.0%) after localization. No patients required chest tube insertion or resuscitation. Conclusions: Strategic needle approach paths provide precise localization of deep thoracic pulmonary nodules with minimal complications. These methods offer a practical framework for improving thoracoscopic surgery in challenging deep thoracic cases. Full article

Background/Objectives: The use of goal-directed fluid therapy (GDFT) guided by stroke volume (SV) variation during thoracic surgery, particularly with one-lung ventilation (OLV) and protective ventilation strategies, is not well established. This study aimed to determine whether maximizing stroke volume (SV) before initiating one-lung ventilation (OLV) reduces the incidence of intraoperative hypotension requiring vasoactive agents during video-assisted thoracoscopic surgery (VATS). Methods: Sixty patients undergoing VATS were randomly assigned to an SVM group (n = 30) or a control group (n = 30). The SVM group received 6% hydroxyethyl starch before OLV to achieve and maintain an SV increase of less than 10%. The control group received no active fluid therapy before OLV positioning. Both groups received Ringer’s lactate solution intraoperatively based on baseline (control) or maximized (SVM) SV goals. The primary outcome was the use of vasoactive agents for hypotension. Results: Patients in the SVM group received significantly less Ringer’s lactate solution than controls (4.2 ± 2.4 vs. 6.1 ± 2.8 mL/kg/h, p = 0.005). While fewer patients in the SVM group required vasoactive agents (20% vs. 40%), the difference was not statistically significant (p = 0.091). IL-6 levels were significantly lower during OLV in the SVM group. Conclusions: Pre-OLV SVM was associated with reduced intraoperative crystalloid administration and attenuation of inflammatory response, with a non-significant trend toward lower vasopressor use. These findings suggest a potential benefit of SVM in thoracic surgery, though larger multicenter trials are needed to confirm clinical efficacy. Full article

Background/objectives: This study aimed to investigate the impact of single-inhaler triple therapy on selecting treatment for lung cancer and the perioperative period in lung cancer patients with chronic obstructive pulmonary disease (COPD) and a forced expiratory volume in 1 s (FEV₁) <1.5 L. Methods: All patients had baseline FEV₁ < 1.5 L. The therapeutic drug for COPD, fluticasone furoate/umeclidinium/vilanterol, was initiated 2 weeks preoperatively and continued until 3 months postoperatively. Radical surgery was actively recommended for patients with an FEV₁ ≥ 1.5 L after COPD treatment; otherwise, palliative surgery and postoperative complication risks were discussed. Results: Among 675 lung cancer patients, 214 (31.7%) had COPD, 41 of whom with FEV₁ < 1.5 L were enrolled. After triple-inhaler therapy, FEV₁ improved to ≥1.5 L in 63.4% of patients. Significant differences in the Brinkman index (840 vs. 1120, p = 0.0058) and radical resection (88.5% vs. 40.0%, p = 0.0030) were observed between patients with FEV₁ ≥ 1.5 L and <1.5 L post-treatment. Pneumonia and home oxygen therapy occurred in two cases (4.9%) and one case (2.4%), respectively, all of which were patients with FEV₁ < 1.5 L post-treatment. Among patients undergoing anatomical lung resection, triple-inhaler therapy significantly improved not only post-inhalation FEV₁ (1.26 vs. 1.55 L, p < 0.0001), but also FEV₁ at 3 months postoperatively compared to the value before inhalation (1.31 vs. 1.26 L, p = 0.042). Conclusions: Preoperative triple therapy in lung cancer patients with untreated COPD and FEV₁ < 1.5 L improved respiratory function and increased the feasibility of performing radical resection surgery. Furthermore, it was considered safe and effective, indicating the potential to maintain preoperative respiratory function without increasing perioperative complications. Full article

Video-assisted thoracoscopic surgery (VATS) is a minimally invasive diagnostic and therapeutic procedure utilized in various thoracic conditions. VATS has grown in popularity with ever-expanding knowledge of enhanced recovery after surgery (ERAS) protocols and its benefits regarding patient care and outcomes. Pain control following VATS is of utmost importance to minimize the complication risk. Options for pain control following VATS have traditionally included systemic IV analgesia but have evolved to include loco-regional analgesia as well. The serratus anterior plane block (SAPB) is one form of loco-regional analgesia utilized in VATS that has been shown to provide effective pain control of the anterolateral chest wall. Patients who received SAPB compared to control methods of anesthesia demonstrated significant decreases in postoperative pain and postoperative opioid consumption. SAPB is effective and offers a promising safety profile as the block is typically more superficial than other types of loco-regional analgesia. This review outlines the recent literature surrounding the use of SAPB for pain control in VATS. Full article

Background: Previous studies have shown that ventilation strategies used in general anesthesia influence perioperative outcomes of video-assisted thoracoscopic surgery (VATS). This study investigated the perioperative effects of non-intubated anesthesia (NIA) versus intubated anesthesia (IA) in patients with early-stage non-small cell lung cancer (NSCLC) undergoing VATS. Methods: This retrospective cohort study analyzed patients who underwent elective VATS for early-stage NSCLC between January 2015 and December 2022. Patients were categorized into the NIA and IA groups based on the ventilation strategies during general anesthesia. Comprehensive outcome data, including intraoperative and postoperative variables, were compared between the two groups. Univariate and multivariate logistic regression models were used to assess the odds ratios for conversion from NIA to IA. Results: A total of 372 patients who received NIA and 1560 who received IA for VATS were eligible for analysis. After propensity score matching, 336 patients were included in each group. In the matched analysis, patients who received NIA demonstrated favorable perioperative outcomes, including reduced opioid consumption, lower postoperative complication rates, and shorter hospital stays, compared to those who received IA. Additionally, patients with a lower baseline oxygen saturation and those who experienced intraoperative pulmonary and cardiovascular adverse events had a higher risk of conversion from NIA to IA. Conclusions: NIA during VATS in patients with early-stage NSCLC was associated with superior perioperative outcomes. Prospective studies are warranted to further evaluate the impact of NIA on perioperative outcomes in this patient population. Full article
