Background: Acute pain after video-assisted thoracoscopic surgery (VATS) promotes respiratory splinting, impaired cough, and pulmonary complications, and predicts persistent opioid use. Surgeon-administered intercostal nerve block (ICNB) is a simple regional technique, but its independent effect on early pain and opioid requirement in a contemporary uniportal VATS (UVATS) pathway is incompletely defined. Methods: We performed a retrospective cohort study of 456 consecutive patients undergoing UVATS at a single Israeli center between 2017 and 30 May 2025. Patients receiving an intercostal block were compared with those who did not. Baseline covariates were balanced by 1:1 nearest-neighbor propensity-score matching (caliper 0.2 SD of the logit propensity score). The primary endpoints were pain on postoperative day (POD) 1 (visual analog scale, VAS) and postoperative opioid use; secondary endpoints included later pain, analgesic regimen, postoperative pneumonia, and mortality. Results: Matching yielded 159 patients per group (n = 318) with all clinically relevant covariates balanced (standardized mean difference [SMD] < 0.13). Median POD1 VAS was lower with the block (4 [IQR 3–4] vs. 5 [5–7]; p < 0.001), and 76.1% of block patients were opioid-free versus 10.7% who were not (p < 0.001). The effect was concentrated early and attenuated by POD3. In multivariable analysis the block was independently associated with lower POD1 VAS (adjusted β = −1.64, 95% CI −2.00 to −1.29; p < 0.001). Postoperative pneumonia was less frequent in the block group (5.7% vs. 20.1%; p < 0.001). Thirty-day and one-year mortality did not differ significantly. Conclusions: In UVATS, a surgeon-placed intercostal nerve block was associated with lower early postoperative pain that persisted after adjustment for operating surgeon and surgical era, concordant with pooled meta-analytic estimates; associated reductions in opioid use and pneumonia were confounded with surgeon and secular trend and are hypothesis-generating. These single-center, retrospective findings require prospective, protocol-randomized confirmation. Full article

Background: Direct comparisons between uniportal robotic-assisted (uRATS) and uniportal video-assisted (uVATS) thoracoscopic anatomical lung resection for non-small cell lung cancer (NSCLC) remain scarce. We compared oncologic radicality and perioperative outcomes between the two uniportal approaches in a single-center contemporaneous cohort. Methods: This retrospective cohort study included 56 consecutive NSCLC patients undergoing uniportal anatomical resection between January 2024 and December 2025 (uRATS, n = 12; uVATS, n = 44). The primary endpoint was oncologic radicality of lymph-node dissection (stations sampled, total nodes, mediastinal sampling, R0 rate). Secondary endpoints included operative time, blood loss, pain, recovery metrics, and a composite textbook outcome. Comparisons used Mann–Whitney U and Fisher’s exact tests. Results: Complete (R0) resection was achieved in all 56 patients. The operating surgeon dissected more lymph nodes in the uRATS group (median 13 vs. 7; p = 0.049), with a trend toward more mediastinal stations sampled (4 vs. 3; p = 0.061). Operative time was longer with uRATS (220 vs. 135 min; p < 0.001), but air-leak duration (0 vs. 2 days; p < 0.001), hospital stay (2 vs. 3 days; p = 0.022), and discharge pain (p = 0.017) all favored uRATS. Textbook outcome was achieved in 83% versus 48% (p = 0.047). Conclusions: In a uniportal-experienced unit, uRATS showed comparable intraoperative oncologic-quality metrics to uVATS with directional perioperative-recovery differences favoring uRATS. Larger multicenter studies with longer follow-up are warranted. Full article

Background/Objectives: In ovarian cancer, the association between low muscle mass and outcomes is unclear, despite well-established evidence in other cancer diagnoses. Overall body composition may have greater prognostic value. This study aimed to investigate associations between body composition and clinical outcomes. Methods: Retrospective study of women diagnosed with ovarian cancer between August 2020 and March 2024. Clinical characteristics were extracted from medical records. Body composition phenotypes (low skeletal muscle index [SMI], low skeletal muscle density [SMD], high subcutaneous [SATI], visceral [VATI] and total adipose tissue index [TATI]) were assessed from pre-treatment CT images. Logistic regression, chi-squared, Fisher’s exact tests, and Mann–Whitney U tests were used to assess associations between body composition phenotypes, patient characteristics and study outcomes. Cox proportional hazards models were fitted to examine associations with survival. Results: Ninety-nine patients [mean (SD) age 61 (12.7) years, 80% stage III/IV] were included. Overall, 67 (67%) women had low SMI, 57 (57%) low SMD, and 49 (49%) high TATI. Thirty-seven (37%) women had low SMI and low SMD, 23 (23%) low SMI with high TATI, and 33 (33%) low SMD with high TATI. Post-menopausal status was associated with higher VAT (p = 0.004). Low SMI or low SMD co-occurring with high adiposity was associated with a 1.91–2.03 and 2.15–2.49 higher hazard mortality. There was insufficient or weak evidence of an association between body composition and other treatment outcomes. Conclusion: These findings suggest additive effects when phenotypes co-occur. In ovarian cancer, singular assessments may be an oversimplification. Future studies should continue to consider co-occurring phenotypes to adequately capture risk. Full article

Objectives: To evaluate the short-term safety (30-day and in-hospital morbidity and mortality) and technical feasibility of uniportal video-assisted thoracic surgery (U-VATS) for anatomical lung resection in octogenarians (≥80 years) compared with younger patients (<80 years) at a single center. Methods: Ninety consecutive patients undergoing U-VATS anatomical lung resections between January 2020 and January 2024 were retrospectively analyzed. Patients were stratified by age: 60 patients < 80 years and 30 octogenarians ≥ 80 years. Propensity score matching (nearest-neighbor, 1:2 ratio, caliper 0.2 SD) yielded a matched cohort of 60 patients (40 younger, 20 octogenarians) for comparative analysis. Results: After matching, standardized mean differences (SMD) were <0.25 for most covariates, indicating good balance. Octogenarians demonstrated lower FEV1 (75.2 ± 15.3% vs. 87.5 ± 18.2%, p = 0.012) and DLCO (68.4 ± 12.1% vs. 78.5 ± 14.3%, p = 0.009), consistent with age-related pulmonary changes. Charlson Comorbidity Index was higher (5.3 ± 1.2 vs. 3.8 ± 1.4, p = 0.001). Surgical parameters were comparable: operative time (143.80 ± 42.3 vs. 136.55 ± 38.7 min, p = 0.524), blood loss (median 80 [IQR 50–120] vs. 95 [IQR 60–130] mL, p = 0.742). Zero conversions occurred. Major complications (Clavien–Dindo ≥ 3) occurred in 10% vs. 0% (absolute risk difference 10%, 95% CI: −3.2% to 23.2%). No 30-day mortality. 90-day mortality: 5% vs. 0% (p = 0.333); one-year: 15% vs. 0% (p = 0.035). Conclusions: U-VATS is technically feasible in carefully selected octogenarians with comparable intraoperative parameters to younger patients. Postoperative recovery differed meaningfully, with higher delirium rates, longer hospitalization, and greater rehabilitation needs. One-year mortality was higher in octogenarians, reflecting competing comorbid risk rather than surgical harm. Residual imbalance in comorbidity burden and pulmonary reserve after matching limits causal inference. These hypothesis-generating findings support U-VATS in selected octogenarians when comprehensive geriatric assessment and structured delirium prevention guide perioperative management; validation in larger multicenter prospective studies is required.

Background/Objectives: This study aimed to assess the safety and efficacy of lung surgery for the treatment of early-stage non-small cell lung cancer (NSCLC) in octogenarians, with a specific focus on the Uniportal-VATS approach, evaluating surgical outcomes and short-term oncological results within a precision medicine perspective. Methods: This retrospective, single-center study included octogenarian patients who underwent surgical treatment for early-stage NSCLC between January 2018 and March 2024. Among 1329 patients treated during the study period, 136 octogenarians were carefully evaluated by a multidisciplinary board and selected for surgical management. Results: The mean age was 82.41 ± 2.72 years, with a prevalence of men (63.2%). In 107 (78.7%) cases, lung resection was performed using the Uniportal-video-assisted thoracic surgery (U-VATS) approach. Overall, 71 lobectomies (52.2%) and 65 segmentectomies or wedge resections (47.8%) were performed, balancing oncological radicality with comorbidities. Only minor complications occurred, such as atelectasis (2.9%), atrial fibrillation (4.4%), pneumonia (1.5%), or air-leakage (2.2%). Factors significantly associated with postoperative complications included open approach (p = 0.014), lobectomy as the extent of resection (p = 0.008), and chronic obstructive pulmonary disease (COPD) (p = 0.010). On multivariable analysis, lobectomy remained the only independent predictor for postoperative complications (OR: 5.95, 95% CI [1.24–28.62], p = 0.026). In-hospital and 90-day mortality were null. The median length of hospital stay in octogenarians was 6 days and was significantly shorter in the Uniportal-VATS group compared with the open surgery one (p < 0.001). All patients were discharged home independently. One- and three-year overall survival rates were 88% and 71%, respectively. No risk factor was associated with mortality in our series. Conclusions: Lung surgery, particularly the Uniportal-VATS approach, appears to be a safe and effective treatment option for octogenarian patients with early-stage NSCLC, provided that patient selection is carefully based on individual clinical characteristics within a multidisciplinary framework based on individualized risk stratification. When feasible, sublobar resection should be preferred in order to minimize postoperative complications. Full article

Background/Objectives: Pseudomonas aeruginosa is one of the leading causes of ventilator-associated pneumonia (VAP) and ventilator-associated tracheobronchitis (VAT), with a worldwide spread of difficult-to-treat high-risk clones. This study aimed to investigate the virulence potential and to characterize phenotypic and genotypic antimicrobial resistance (AMR) in P. aeruginosa causing VAP/VAT in the Intensive Care Unit (ICU), University Hospital of Split, Croatia. Methods: The study included P. aeruginosa isolates obtained from ICU patients who met the criteria for VAP or VAT, between January 2023 and January 2024. Isolates were identified using MALDI-TOF MS and tested for antimicrobial susceptibility (AST). A subset of phenotypically multidrug-resistant (MDR) isolates was further analyzed using whole-genome sequencing (WGS) and multilocus sequence typing. Results: A high rate of resistance was detected to ceftazidime (23.4%), imipenem (39.6%), and meropenem (43.8%). WGS confirmed the presence of multiple AMR genes, including the bla_VIM-2 gene, whose genetic environment highlights a complex MDR locus integrating multiple AMR determinants and mobile genetic elements. All tested isolates possessed genes for class C (bla_PDC34, bla_PDC374 or bla_PDC16) and class D (bla_OXA-2, bla_OXA-10 or bla_OXA-50) β-lactamases, fosA, aph(3′)-IIb and crpP genes. Additionally, WGS analysis revealed the presence of numerous virulence genes including those for adherence (Type IV pili and Fap protein production), motility (such as flgF), biofilm formation (e.g., algE and mucE), quorum sensing (lasI, lasR, rhlI and rhlR), exotoxin (toxA and plcH) and exoenzyme activity (exoU, exoT, exoS, exoY, pcrV, hcp1 and lasA). The isolates belonged to four different sequence types: ST235, ST446, the high-risk ST253 and the widely distributed ST395. Phylogenomic comparison demonstrated that the isolates from this study do not originate from a single clonal source, but instead represent multiple globally distributed high-risk P. aeruginosa lineages introduced into the clinical setting. Conclusions: Due to the emergence of high-risk clones with broad AMR and strong virulence potential, ineffectiveness of standard empirical therapy may be anticipated, highlighting the urgent need for new therapeutic approaches (including those targeting major virulence factors).

Background/Objectives: Minimally invasive thoracic surgery has evolved rapidly, with uniportal video-assisted thoracoscopic surgery (U-VATS) and robotic-assisted thoracic surgery (RATS). Biportal-RATS (Bi-RATS) has emerged as a hybrid technique, combining robotics advantages with the reduced invasiveness of U-VATS. The aim of this study was to evaluate the safety, perioperative outcomes, lymphadenectomy, and postoperative quality of life (QoL) of Bi-RATS compared with U-VATS for lung resections. Methods: This single-center, observational cohort study included 130 consecutive patients undergoing anatomical lung resection between December 2021 and December 2024. Baseline and perioperative characteristics, including complications, chest drain duration, hospital stay, and lymph node yield, were analyzed. Health-related QoL was assessed preoperatively and 6 months postoperatively using the EQ-5D-5L questionnaire and EQ-VAS. Propensity score matching (PSM) at a 1:1 ratio was performed to minimize selection bias, obtaining 32 patients per group. Results: After PSM, the baseline characteristics were comparable between groups. Operative time was longer with Bi-RATS (221.3 ± 84.5 vs. 119.3 ± 53.4 min, p < 0.001). No significant differences were observed in postoperative complications, drain duration, or hospital stay. Bi-RATS seemed to be associated with a higher lymph node yield, particularly in segmentectomies. At 6 months, the overall EQ-VAS was comparable between techniques (78.9 U-VATS vs. 78.1 Bi-RATS; p = 0.832), while among the EQ-5D-5L dimensions, only mobility favored Bi-RATS (p = 0.045). Conclusions: Bi-RATS appears safe and effective, with perioperative outcomes and overall EQ-VAS comparable to those of U-VATS 6 months after surgery. These findings suggest that Bi-RATS may represent a valuable evolution of minimally invasive thoracic surgery. Full article

Background: Spontaneous ventilation with intubation (SVI) during video-assisted thoracoscopic surgery (VATS) has been introduced as a hybrid technique that combines the physiological benefits of spontaneous breathing with the safety of a secured airway. However, its application in patients with chronic obstructive pulmonary disease (COPD) remains controversial due to concerns about hypercapnia, hypoxemia, and dynamic hyperinflation. To date, no study has directly compared COPD and non-COPD patients undergoing VATS lobectomy under SVI using identical anesthetic and surgical protocols. Methods: A prospective observational study was conducted between January 2022 and December 2024 at a single tertiary thoracic surgery center. A total of 36 patients undergoing elective VATS lobectomy with SVI were included and divided into two groups: COPD (n = 17) and non-COPD (n = 19), based on GOLD criteria. All patients were intubated with a double-lumen tube and allowed to maintain spontaneous ventilation during one-lung ventilation (OLV) after recovery from neuromuscular blockade. Arterial blood gas (ABG) samples were collected at four predefined time points (T1–T4), and intraoperative respiratory parameters, hemodynamics, spontaneous ventilation time, and spontaneous ventilation fraction (SpVent%) were recorded. Postoperative outcomes, including ICU stay, complications, and conversion to controlled ventilation, were analyzed. Statistical comparisons were performed using t-test, Mann–Whitney U test, chi-square test, and ANCOVA with adjustment for age, sex, BMI, and FEV₁%. Results: All 36 procedures were successfully completed under SVI without conversion to controlled mechanical ventilation or thoracotomy. Baseline demographics were comparable between COPD and non-COPD patients regarding age (68.4 ± 6.9 vs. 67.8 ± 7.1 years; p = 0.78) and BMI (27.1 ± 4.6 vs. 26.3 ± 4.2 kg/m²; p = 0.56), while pulmonary function was significantly lower in COPD patients (FEV₁/FVC 53.8% (IQR 47.5–59.9) vs. 82.4% (78.5–85.2); p < 0.001). The duration of spontaneous ventilation was significantly longer in the COPD group (82 ± 14 min vs. 58 ± 16 min; p < 0.001), and remained significant after ANCOVA adjustment (β = +23.7 min; p = 0.001). The SpontVent% was higher in COPD patients (80% [70–90] vs. 60% [45–80]), showing a trend toward significance (p = 0.11). Intraoperative permissive hypercapnia was well tolerated: peak PaCO₂ levels at T3 were higher in COPD (52 ± 6 mmHg) than in non-COPD patients (47 ± 5 mmHg; p = 0.06), without pH dropping below 7.25 in either group. No significant differences were observed in mean arterial pressure, oxygen saturation, ICU stay (1.1 ± 0.4 vs. 1.0 ± 0.5 days; p = 0.48), or postoperative complication rates (p = 0.67). All patients were extubated in the operating room. Conclusions: Intubated spontaneous ventilation during VATS lobectomy is feasible and safe in both COPD and non-COPD patients when performed by experienced teams. COPD patients, despite impaired baseline lung function, were able to maintain spontaneous breathing for significantly longer periods without developing severe hypercapnia, acidosis, or hemodynamic instability. These findings suggest that SVI may represent a lung-protective alternative to fully controlled one-lung ventilation, particularly in hypercapnia-adapted COPD patients. Further multicenter studies are warranted to validate these results and define standardized thresholds for CO₂ tolerance, patient selection, and intraoperative monitoring during SVI. Full article

Ultrasonic-assisted machining (UAM) has emerged as a transformative technology for increasing material removal efficiency, improving surface quality and extending tool life in precision manufacturing. This review specifically focuses on the application of it to titanium aluminide (TiAl) alloys. These alloys are widely used in aerospace and automotive sectors due to their low density, high strength and poor machinability. This review covers various aspects of UAM, including ultrasonic vibration-assisted turning (UVAT), milling (UVAM) and grinding (UVAG), with emphasis on their influence on the machinability, tool wear behavior and surface integrity. It also highlights the limitations of single-energy field UAM, such as inconsistent energy transmission and tool fatigue, leading to the increasing demand for multi-field techniques. Therefore, the advanced machining strategies, i.e., ultrasonic plasma oxidation-assisted grinding (UPOAG), protective coating-assisted cutting, and dual-field ultrasonic integration (e.g., ultrasonic-magnetic or ultrasonic-laser machining), were discussed in terms of their potential to further improve TiAl alloys processing. In addition, the importance of predictive force models in optimizing UAM processes was also highlighted, emphasizing the role of analytical and AI-driven simulations for better process control. Overall, this review underscores the ongoing evolution of UAM as a cornerstone of high-efficiency and precision manufacturing, while providing a comprehensive outlook on its current applications and future potential in machining TiAl alloys.

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: 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.

Background: Emphysema is a chronic lung disease characterized by alveolar wall destruction, leading to impaired gas exchange. Giant bullous emphysema (GBE) is a severe form of emphysema, often requiring surgical intervention. Video-assisted thoracoscopic surgery (VATS) is a minimally invasive approach for various thoracic pathologies, including lung volume reduction surgery (LVRS) and bullectomy for emphysematous bullae. Uniportal VATS (U–VATS), a further refinement, offers benefits such as reduced postoperative pain and faster recovery. Methods: This retrospective study analyzed data from two high-volume European Thoracic Surgery centers between August 2016 to January 2024. A total of 29 patients underwent U–VATS bullectomy for GBE. Results: Nineteen patients were males (65.5%) with a mean age of 44.7 ± 8.8 years. Ten (34.5%) were active smokers. Eighteen patients (62.1%) presented with a single giant bulla, while the remaining cases were in the context of pulmonary emphysema. Four patients (13.8%) presented with pneumothorax, with one requiring preoperative chest drainage. Twenty-eight patients (96.6%) underwent only U–VATS bullectomy, with additional chemical pleurodesis in eleven cases (37.9%). One patient (3.4%) underwent a left upper lobectomy for a giant bulla and NSCLC. In cases of severe lung emphysema and fragile pulmonary tissue, the stapler line was buttressed with Gore^® Seamguard^®. No conversions to thoracotomy, postoperative air-leaks, or major complications were recorded. At a mean follow-up time of 22.0 ± 14.0 months, no pneumothorax recurrence was documented. At about six months after surgery, pulmonary function significantly improved. Conclusions: U–VATS bullectomy appears to be a safe and feasible technique for the treatment of bullae in GBE, offering promising postoperative outcomes. Full article

Background: Minimally invasive thoracic surgery has advanced since the introduction of multiportal video-assisted thoracoscopic surgery (mVATS) in 1991. Primary spontaneous pneumothorax (PSP) is an ideal condition for refining minimally invasive techniques owing to its straightforward procedures and predictable bullae distributions. Methods: Uniportal VATS (uVATS), which involves a single incision, is an alternative to mVATS, offering reduced postoperative pain, lower paresthesia rates, and comparable recurrence outcomes. This review explores two main uVATS approaches: intercostal and subxiphoid. Results: The intercostal approach is common to surgeons trained in mVATS, easier to adopt, and provides excellent cosmetic outcomes. Innovations such as the chest wall pulley method and anchoring sutures further enhance its operability and prevent recurrence. Subxiphoid uVATS minimizes intercostal nerve damage and postoperative pain, making it advantageous for bilateral PSP surgeries. However, it poses challenges such as longer operative times and limited dorsal visualization. Emerging strategies, including drainless postoperative management and two-lung ventilation with CO₂ insufflation, have reduced surgical invasiveness. Additionally, cosmetic techniques such as subaxillary incisions enhance patient satisfaction. Conclusions: uVATS continues to redefine PSP surgery, prioritize patient-centered outcomes, and integrate novel strategies to achieve superior results. Full article

Objectives: The purpose of the present study was to verify if performance in the 6-min walking test (6MWT) during the preoperative evaluation phase is associated with the development of cardiopulmonary postoperative complications in patients who underwent uniportal VATS (U-VATS) for lung cancer. Methods: This retrospective, monocentric study included patients submitted to U-VATS anatomical lung resections (March 2022–December 2023). The patients were enrolled in a preoperative rehabilitation program carried out 15 days before surgery. The 6MWT was performed at counseling (T0) and after pre-habilitation (T1). Univariate analysis followed by logistic regression verified the association of baseline patients’ characteristics and performance in the 6MWT (meters walked during T0 and T1 and the difference between T1 and T0—T1-T0 variation) with postoperative cardiopulmonary complications (CPCs). Youde’s index was used to establish the optimal cut-offs for ergometric parameters significantly correlated with CPCs. Results: We enrolled 212 patients scheduled to undergo U-VATS lung resection (lobectomies: 177; bilobectomies: 2; segmentectomies: 33). Twenty-three (10.8%) patients developed CPCs. None of the baseline patients’ characteristics were associated with CPCs. Complicated patients showed more significant differences compared to non-complicated ones for meters walked during the 6MWT T1 (6MWT-T1-complicated: 450 vs. 6MWT-T1-non-complicated: 517; p: 0.01) and for variation-T1-T0 (variation-T1-T0-complicated: 4 m vs. variation-T1-T0-non-complicated: 20 m; p: 0.02). The best cut-offs for discriminating between patients with CPCs and those with uneventful courses were 458 m for 6MWT-T1 and 31 m for variation-T1-T0. After multivariate analysis, 6MWT-T1 < 458 m and variation-T1-T0 < 31 m were the unique parameters independently correlated with CPCs (p: 0.03 and p: 0.05, respectively). Conclusions: The 6MWT results (in particular, 6MWT-T1 < 458 m and variation-T1-T0 < 31 m) in the context of a pre-habilitation program are associated with the development of CPCs after U-VATS lung resection.

Background: Intraoperative fluid management based on pulse pressure variation has shown potential to reduce postoperative pulmonary complications (PPCs) and improve clinical outcomes in various surgical settings. However, its efficacy and safety have not been assessed in patients undergoing thoracic surgery with one-lung ventilation. Methods: Patients scheduled for pulmonary lobectomy using uniportal video-assisted thoracic surgery approach were randomly assigned to two groups. In the PPV group, fluid administration was guided by the pulse pressure variation parameter, while in the near-zero group, it was guided by conventional hemodynamic parameters. The primary outcome was the partial pressure of oxygen (PaO₂)/ fraction of inspired oxygen (FiO₂) ratio 15 min after extubation. The secondary outcomes included extubation time, the incidence of postoperative pulmonary complications in the first three postoperative days, and the length of hospital stay. Results: The PaO₂/FiO₂ ratio did not differ between the two groups (364.48 ± 38.06 vs. 359.21 ± 36.95; p = 0.51), although patients in the PPV group (n = 44) received a larger amount of both crystalloids (1145 ± 470.21 vs. 890 ± 459.31, p = 0.01) and colloids (162.5 ± 278.31 vs 18.18 ± 94.68, p = 0.002) compared to the near-zero group (n = 44). No differences were found in extubation time, type and number of PPCs, and length of hospital stay. Conclusions: PPV-guided fluid management in thoracic surgery requiring one-lung ventilation does not improve pulmonary gas exchange as measured by the PaO₂/FiO₂ ratio and does not seem to offer clinical benefits. Additionally, it results in increased fluid administration compared to fluid management based on conventional hemodynamic parameters. Full article
