Introduction: Minimally invasive video-assisted thoracic surgery (VATS) for lung cancer has become a widely used approach. However, postoperative pulmonary complications (PCs) such as pneumonia, atelectasis, and lung fistula remain significant challenges, particularly in older adult patients with multiple comorbidities. The 6-minute walk test (6MWT) has been suggested as a predictor of postoperative outcomes in various surgical settings, but its relationship with postoperative complications following VATS lobectomy for lung cancer has not been thoroughly explored. The aim of this study was to determine if preoperative 6MWD predicted the occurrence of 30-day PCs among patients undergoing VATS lobectomy for non-small-cell lung cancer. Methods: This retrospective study examined 66 patients who underwent VATS lobectomy for lung cancer. Participants were categorized into two groups: those with postoperative pulmonary complications (n = 11) and those without (n = 55). The research period was from January to September 2022. The preoperative 6MWT distance, along with other clinical and demographic factors, was assessed to determine its predictive value for postoperative complications. Multivariate logistic regression analysis was performed to identify significant predictors. Results: The study found that preoperative 6MWT ≤ 450 m was a significant predictor of postoperative pulmonary complications (odds ratio: 5.674, 95% CI: 1.206–26.684, p = 0.028). Conclusions: The preoperative 6MWT distance is a useful predictor of postoperative pulmonary complications in patients undergoing VATS lobectomy for lung cancer. Patients with a 6MWT ≤ 450 m may be at higher risk for complications such as pneumonia, atelectasis, and lung fistula. Incorporating preoperative 6MWT as a risk stratification tool could help guide clinical decisions and rehabilitation efforts to improve postoperative outcomes in this patient population.

Background: Discontinuing mechanical ventilation during cardiopulmonary bypass (CPB) is common but may adversely affect postoperative pulmonary function. This study aimed to evaluate the impact of stopping ventilation during CPB on postoperative gas exchange, radiographic findings, intensive care unit (ICU) length of stay (LOS), mortality, reintubation, re-exploration, and bleeding. Methods: A prospective observational study was performed involving adult patients scheduled for elective cardiac surgery requiring CPB. Participants were divided into ventilated and non-ventilated groups according to intraoperative strategy. Postoperative arterial carbon dioxide levels (PaCO₂), arterial partial pressure of oxygen (PaO₂), the PaO₂/FiO₂ ratio (P/F ratio), arterial oxygen saturation (SaO₂), and the ratio of PaCO₂ to minute ventilation (PaCO₂/MV) were measured before the induction of anesthesia (within 5 min after transportation into the operating room), postoperatively within 5–10 min after transportation to the ICU, and in a 24 h postoperative period. Chest X-ray data, mechanical ventilation time, LOS in ICU, re-exploration, reintubation, and bleeding parameters were documented. Analyses were also conducted with the estimation of the age effect and BMI. Results: Individuals in the non-ventilated group exhibited lower postoperative P/F ratios and elevated postoperative PaCO₂ and PaCO₂/MV ratios. The difference in gas exchange leveled off within 24 h. There was no difference in the incidence of atelectasis (postoperatively in a 24 h period), mechanical ventilation time, LOS in ICU, or mortality. However, the incidence of bleeding was higher in the non-ventilated group (χ² = 5.78, p = 0.016). Interestingly, postoperative PaCO₂ and PaCO₂/MV peaked in the 50-year age group. Conclusions: Continued mechanical ventilation during CPB correlates with better postoperative gas exchange, better CO₂ clearance, and fewer bleeding events. The results suggest that maintaining low tidal volume ventilation during CPB may provide benefits, especially for patients aged 50 years. Full article

Background: Pulmonary lobectomy remains the gold standard for early-stage non-small cell lung cancer, with the primary goal of complete tumor removal. Postoperative imaging is critical for evaluating recovery and identifying complications, yet systematic descriptions of radiologic patterns after lobectomy are limited. Methods: We conducted a retrospective analysis of 125 patients who underwent pulmonary lobectomy between 2019 and 2024 at a tertiary thoracic surgery center. Preoperative and postoperative imaging findings were coded and compared using a standardized classification system. Modalities included chest radiography, thoracic CT, ultrasound, PET-CT and MRI. Results: Postoperative imaging demonstrated a clear reduction in pathological findings. Emphysema decreased from 29.6% to 21.6%, pleural effusion from 12.8% to 3.2%, atelectasis/pleural thickening from 15.2% to 8.8%, and ground-glass infiltrates from 12.0% to 8.0%. The proportion of patients without abnormalities increased from 18.5% to 24.8%. Chest radiography (92%) and CT (89.6%) were the most frequently employed modalities. Patients treated with VATS lobectomy showed slightly fewer postoperative abnormalities compared with those undergoing open surgery. Conclusions: Pulmonary lobectomy is associated with measurable radiologic improvement, reflecting favorable structural recovery. Routine imaging follow-up, particularly chest radiography, remains essential for early detection of complications and guiding postoperative care. However, the retrospective single-center design and limited generalizability represent important limitations that should be considered when interpreting these findings. Full article

Malignant mediastinal tumors are a group representing some of the most demanding oncological challenges for early, multi-level, and successful management. The timely identification of any suspicious clinical symptomatology is urgent in achieving an accurate, staged histological diagnosis, in order to follow up with an equally detailed medical therapeutic plan (interventional or not) and determine the principal goals regarding efficient overall treatment in these patients. We report a case of a 24-year-old male patient with an incident-free prior medical history. An initial chest X-ray was performed after the patient reported short-term, consistent moderate chest pain symptomatology, early work fatigue, and shortness of breath. The following imaging procedures (chest CT, PET-CT) indicated the presence of an anterior mediastinal mass (meas. ~11 cm × 10 cm × 13 cm, SUV: 8.7), applying additional pressure upon both right heart chambers. The Alpha-Fetoprotein (aFP) blood levels had exceeded at least 50 times their normal range. Two consecutive diagnostic attempts with non-specific histological results, a negative-for-malignancy fine-needle aspiration biopsy (FNA-biopsy), and an additional tumor biopsy, performed via mini anterior (R) thoracotomy with “suspicious” cellular gatherings, were performed elsewhere. After admission to our department, an (R) Video-Assisted Thoracic Surgery (VATS) was performed, along with multiple tumor biopsies and moderate pleural effusion drainage. The tumor’s measurements had increased to DMax: 16 cm × 9 cm × 13 cm, with a severe degree of atelectasis of the Right Lower Lobe parenchyma (RLL) and a pressure-displacement effect upon the Superior Vena Cava (SVC) and the (R) heart sinus, based on data from the preoperative chest MRA. The histological report indicated elements of a combined, non-seminomatous germ-cell mediastinal tumor, posthuberal-type teratoma, and embryonal carcinoma. The imminent chemotherapeutic plan included a “BEP” (Bleomycin^®/Cisplatin^®/Etoposide^®) scheme, which needed to be modified to a “VIP” (Cisplatin^®/Etoposide^®/Ifosfamide^®) scheme, due to an acute pulmonary embolism incident. While the aFP blood levels declined, even reaching normal measurements, the tumor’s size continued to increase significantly (DMax: 28 cm × 25 cm × 13 cm), with severe localized pressure effects, rapid weight loss, and a progressively worsening clinical status. Thus, an emergency surgical intervention took place via median sternotomy, extended with a complementary “T-Shaped” mini anterior (R) thoracotomy. A large, approx. 4 Kg mediastinal tumor was extracted, with additional RML and RUL “en-bloc” segmentectomy and partial mediastinal pleura decortication. The following histological results, apart from verifying the already-known posthuberal-type teratoma, indicated additional scattered small lesions of combined high-grade rabdomyosarcoma, chondrosarcoma, and osteosarcoma, as well as numerous high-grade glioblastoma cellular gatherings. No visible findings of the previously discovered non-seminomatous germ-cell and embryonal carcinoma elements were found. The patient’s postoperative status progressively improved, allowing therapeutic management to continue with six “TIP” (Cisplatin^®/Paclitaxel^®/Ifosfamide^®) sessions, currently under his regular “follow-up” from the oncological team. This report underlines the importance of early, accurate histological identification, combined with any necessary surgical intervention, diagnostic or therapeutic, as well as the appliance of any subsequent multimodality management plan. The diversity of mediastinal tumors, especially for young patients, leaves no place for complacency. Such rare examples may manifest, with equivalent, unpredictable evolution, obliging clinical physicians to stay constantly alert and not take anything for granted. Full article

Background/Objectives: Lung-protective ventilation (LPV) reduces postoperative pulmonary complications (PPCs) in obese patients. While the roles of low tidal volume and positive end-expiratory pressure (PEEP) in LPV have been established in patients with healthy lungs, the protective effect of alveolar recruitment strategies (ARSs) remains a subject of debate. This study aims to evaluate the benefit of ARSs in patients with low-to-moderate risk according to the Assess Respiratory Risk in Surgical Patients in Catalonia (ARISCAT) score undergoing gynecologic cancer surgery with LPV and low tidal volume intraoperatively. Methods: A total of 88 obese patients were evaluated in this study. They were divided into two groups as the non-ARS group (non-ARS) and the ARS group (ARS). Intraoperative hemodynamics, blood gas analyses, respiratory mechanics, mechanical ventilator parameters, and postoperative outcomes were compared in these obese patients. Results: A total of 40 obese patients undergoing major gynecological cancer surgery were included in this study. Although the non-ARS group presented with higher weight (p < 0.05), body mass indexes were similar to the ARS group. Intraoperative blood gas analysis revealed higher end-tidal carbon dioxide (etCO₂) levels in the non-ARS group during the T2 and T3 time intervals (p < 0.05). In the ARS group, peak inspiratory pressure (PIP) at T3 was lower, while drive pressures at T1 and T2 and dynamic compliance at T3 were higher (p < 0.05). Radiologic atelectasis scores were higher in the non-ARS group, indicating more atelectatic lung images (p < 0.05). PPC rates were similar across both groups. Conclusions: Although the ARS demonstrated positive effects on lung mechanics and radiologic atelectasis scores in major open gynecologic cancer surgeries, it did not effectively reduce postoperative pulmonary complications.

Background: Upper abdominal surgeries exceeding two hours and operated in a lateral decubitus position present an “intermediate” risk for pulmonary complications. The objectives of this study were to observe the sonographic and clinical changes during and after surgeries with one recruitment maneuver (RM) performed intraoperatively before extubation. Methods: Laparoscopic nephrectomy patients were randomized into pre-extubation single RM (Group RM) and control (Group NoRM) groups. The LUS (Lung Ultrasound Score) was evaluated after intubation (T1), at the end of surgery before the RM (T2), after the RM but before extubation (T3), and 30 min after arrival to the Post-Anesthesia Care Unit (T4) in Group RM; in Group NoRM, it was evaluated at the T1, T2, and T4 time points. The primary outcome was the effect on the pre-extubation LUS (T2 in Group NoRM versus T3 in Group RM). The secondary outcomes included the effects on the T4 LUS, PPC occurrence, and PaO₂/FiO₂ ratios, and the sensitivity and specificity of the LUS in predicting PPCs. Results: The data of 54 patients were analyzed. The pre-extubation LUS was significantly lower in Group RM (16 (12.5, 17) vs. 18 (17, 20), p < 0.001). The T4 LUS was only different in the upper zones in the dependent lung (2 (1, 3.5) in Group RM vs. 4 (3, 4.5) in Group NoRM, p = 0.01). The perioperative PaO₂/FiO₂ ratios were similar (p > 0.05). The pre-extubation LUS exhibited 91% sensitivity (p = 0.04), whereas the T4 LUS sensitivity was 82% (p = 0.01). The PPC risk was 10-fold higher in patients with a pre-extubation LUS exceeding 19. Conclusions: A pre-extubation single RM instantly increases the LUS. However, this does not persist postoperatively or diminish respiratory complications. More importantly, the LUS was found to be a sensitive tool for predicting PPCs when performed just before extubation. Full article

Introduction: Optimal control of acute postoperative pain after major surgery accelerates the recovery process, shortens hospital stays, and minimizes healthcare costs. Intrathecal morphine is a simple, safe, and reliable regional technique that provides prolonged analgesia, useful in a wide variety of procedures. Materials and Methods: A retrospective observational study was conducted on patients who underwent various major abdominal or thoracic surgical procedures and were administered intrathecal morphine between January 2018 and December 2021. The primary objective was to establish the safety of the technique in terms of the incidence of early and late respiratory depression, atelectasis, the need for respiratory support, and the possible association of these complications with the presence of respiratory pathologies such as chronic obstructive pulmonary disease (COPD) or sleep apnea–hypopnea syndrome (SAHS) and obesity or smoking habit. Secondary objectives included recording the consumption of rescue intravenous (IV) morphine in the first postoperative 24 h, the incidence of PONV, and the incidence of late postoperative complications (at 90 days) such as pneumonia, readmission rates, and reoperation rates. Hospital stay and mortality were also recorded. Results: A total of 484 patients were included in the study. No patient experienced respiratory depression. Atelectasis occurred in 2.07% of patients. Respiratory support with non-invasive mechanical ventilation (NIMV) or high-flow oxygen therapy (HFOT) was required by 1.86% of patients. In total, 51% of patients required rescue IV morphine (average 6.98 mg), with a rate significantly higher in the thoracic and general surgery groups compared to urological surgery. The incidence of postoperative nausea and vomiting (PONV) was 30.37%. Regarding other secondary objectives, readmissions, reoperations, and mortality rates were significantly higher in patients undergoing urological and thoracic surgery compared to those undergoing general surgery. Conclusions: The administration of intrathecal morphine for the control of acute postoperative pain after major surgery can be considered as a safe technique that fits perfectly within the set of measures for a multimodal approach to pain management in major abdominal and thoracic surgery.

Background: Postoperative physiotherapy is a cornerstone of Enhanced Recovery After Surgery (ERAS) programs, especially following lung resection. Despite its importance, the literature lacks clear recommendations and guidelines, particularly regarding the role of incentive spirometry (IS). This study aims to determine whether incentive spirometry offers additional benefits over early ambulation alone in patients undergoing lung resection for primary lung cancer. Methods: We conducted a retrospective case–control study at the European Institute of Oncology (IEO) involving patients who underwent lung resection from June 2020 to June 2022. Patients were divided into two cohorts: early ambulation alone (control group) and early ambulation with IS (IS group). The primary endpoint was the rate of postoperative pulmonary complications. Secondary endpoints included length of hospital stay and time to chest drain removal. A propensity score-matched analysis was performed based on age, sex, and BMI. Data were compared using Chi-squared and Student’s t-tests as appropriate. Results: A total of 304 patients were included, with 153 in the intervention group and 151 in the control group. After propensity-score matching, 52 patients from each cohort were compared. No significant differences were found between the groups regarding postoperative oxygen requirement, fever, atelectasis, residual pleural space, need for bronchoscopy toilette, and re-hospitalization rate. IS group showed trends toward shorter hospital stays and lower time to chest drain removal, though without reaching statistical significance. Conclusions: IS did not significantly improve postoperative outcomes compared to early ambulation alone in patients undergoing lung resection for primary lung cancer. More extensive, prospective, randomized trials are needed to confirm these findings. Full article

Pectus excavatum (PE) can be associated with either congenital or acquired heart disease. This study highlights the importance of PE surgical repair in cases of severe chest depression on the heart in underlying cardiac diseases exacerbating cardiopulmonary impairment. From January 2023 to March 2024, four male patients underwent PE repair, having heart disease including pericarditis, mitral valve prolapse, ventricular fibrillation arrest and type 1 second-degree atrioventricular block. PE severity was determined by the Haller index (HI). Preoperative assessment included a pulmonary function test, chest computed tomography and cardiac evaluation. The Nuss procedure was performed in three patients, whereas, in one patient, it was performed in combination with a modified Ravitch procedure. The median HI was five. The median time of chest tube removal was 6.5 days. Postoperative complications were prolonged air leak, atrial fibrillation and atelectasis. The median length of hospital stay was 19.5 days, and no 30-day postoperative mortality was recorded. In all patients, surgical repair helped to resolve the underlying cardiological issues, and surgical follow-ups were deemed regular. PE is generally an isolated congenital chest wall abnormality, and, when associated with a heart disease, it can have severe life-threatening hemodynamic consequences due to mechanical compression on the heart for which surgical corrections should be considered.

Background: Division of the pulmonary ligament is standard in lower lobectomies, but its application in upper lobectomies remains controversial due to potential complications like atelectasis and bronchial kinking. This retrospective matched cohort study aimed to evaluate the efficacy and safety of ligament resection in upper lobectomies for oncological purposes. Methods: From January 2015 to December 2020, 988 patients who underwent minimally invasive upper lobectomies across multiple centers were identified. They were categorized into ligament resection and no ligament resection groups, with propensity score matching (PSM) to minimize confounding factors. Endpoints included operative time, pleural effusion, complications (frequency and Clavien–Dindo scores), chest drainage removal, length of stay, pleural space, collapse rate, and bronchial kinking. Results: Following PSM, 276 patients were included in each group, with no significant differences in baseline characteristics. Ligament resection correlated with longer operative times, increased lymphadenectomy sampling at station #9 (p < 0.001), and a bigger change in the bronchial angle (p < 0.001). No statistically significant differences were observed for the other endpoints. Conclusions: Ligament resection during upper lobectomy may impact the bronchial angle without immediate postoperative outcome changes. Further research is necessary to comprehensively assess the risks and benefits of ligament resection in upper lobectomies for neoplastic disease. Full article

Background: Progressive atelectasis regularly occurs during general anaesthesia; hence, positive end-expiratory pressure (PEEP) is often applied. Individualised PEEP titration may reduce the incidence of postoperative pulmonary complications (PPCs) and improve oxygenation as compared to fixed PEEP settings; however, evidence is lacking. Methods: This systematic review and meta-analysis was registered on PROSPERO (CRD42021282228). A systematic search in four databases (MEDLINE Via PubMed, EMBASE, CENTRAL, and Web of Science) was performed on 14 October 2021 and updated on 26 April 2024. We searched for randomised controlled trials comparing the effects of individually titrated versus fixed PEEP strategies during abdominal surgeries. The primary endpoint was the incidence of PPCs. The secondary endpoints included the PaO₂/FiO₂ at the end of surgery, individually set PEEP value, vasopressor requirements, and respiratory mechanics. Results: We identified 30 trials (2602 patients). The incidence of PPCs was significantly lower among patients in the individualised group (RR = 0.70, CI: 0.58–0.84). A significantly higher PaO₂/FiO₂ ratio was found in the individualised group as compared to controls at the end of the surgery (MD = 55.99 mmHg, 95% CI: 31.78–80.21). Individual PEEP was significantly higher as compared to conventional settings (MD = 6.27 cm H₂O, CI: 4.30–8.23). Fewer patients in the control group needed vasopressor support; however, this result was non-significant. Lung-function-related outcomes showed better respiratory mechanics in the individualised group (Cstat: MD = 11.92 cm H₂O 95% CI: 6.40–17.45). Conclusions: Our results show that individually titrated PEEP results in fewer PPCs and better oxygenation in patients undergoing abdominal surgery. Full article

Purpose: Pulmonary sequestration is a rare pulmonary malformation that often necessitates surgical intervention due to potential complications such as recurrent infections or hemoptysis. This case series presents the clinical trajectory of four patients diagnosed with pulmonary sequestration, from initial diagnosis through postoperative care, with a specific focus on the limited arterial supply in two of the cases. Materials and Methods: We conducted a retrospective descriptive analysis of four patients diagnosed with pulmonary sequestration who underwent surgical treatment at our institution between January 2013 and November 2022. The affected lung segments were excised via either thoracoscopy or thoracotomy. We evaluated perioperative and postoperative complications, hospital stay duration, histological findings, and the vascular supply of the affected areas. Results: Thoracoscopic surgery was initially preferred for all patients, though one required conversion to an open procedure due to technical challenges. Perioperative complications included increased pain and atelectasis. Two patients developed pleural empyema postoperatively, necessitating additional surgical intervention. The overall outcomes were favorable, with appropriate management addressing the complications effectively. Conclusions: Pulmonary sequestration, despite its rarity, often requires surgical treatment. Both thoracoscopic and open surgical methods are effective, though thoracoscopic surgery is generally preferred when feasible. The findings underscore the importance of meticulous preoperative planning and vigilant postoperative care to manage and mitigate potential complications. Full article

Awake surgery has been applied for various surgical procedures with positive outcomes; however, in neurosurgery, the technique has traditionally been reserved for cranial surgery. Awake surgery for the spine (ASFS) is an alternative to general anesthesia (GA). As early studies report promising results, ASFS is progressively gaining more interest from spine surgeons. The history defining the range of adverse events facing patients undergoing GA has been well described. Adverse reactions resulting from GA can include postoperative nausea and vomiting, hemodynamic instability and cardiac complications, acute kidney injury or renal insufficiency, atelectasis, pulmonary emboli, postoperative cognitive dysfunction, or malignant hyperthermia and other direct drug reactions. For this reason, many high-risk populations who have typically been poor candidates under classifications for GA could benefit from the many advantages of ASFS. This narrative review will discuss the significant historical components related to ASFS, pertinent mechanisms of action, protocol overview, and the current trajectory of spine surgery with ASFS.

Background and Objectives: Postoperative pulmonary complications (PPCs) are common in patients who undergo cardiac surgery and are widely acknowledged as significant contributors to increased morbidity, mortality rates, prolonged hospital stays, and healthcare costs. Clinical manifestations of PPCs can vary from mild to severe symptoms, with different radiological findings and varying incidence. Detecting early signs and identifying influencing factors of PPCs is essential to prevent patients from further complications. Our study aimed to determine the frequency, types, and risk factors significant for each PPC on the first postoperative day. The main goal of this study was to identify the incidence of pleural effusion (right-sided, left-sided, or bilateral), atelectasis, pulmonary edema, and pneumothorax as well as detect specific factors related to its development. Materials and Methods: This study was a retrospective single-center trial. It involved 314 adult patients scheduled for elective open-heart surgery under CPB. Results: Of the 314 patients reviewed, 42% developed PPCs within 12 h post-surgery. Up to 60.6% experienced one PPC, while 35.6% developed two PPCs. Pleural effusion was the most frequently observed complication in 89 patients. Left-sided effusion was the most common, presenting in 45 cases. Regression analysis showed a significant association between left-sided pleural effusion development and moderate hypoalbuminemia. Valve surgery was associated with reduced risk for left-sided effusion. Independent parameters for bilateral effusion include increased urine output and longer ICU stays. Higher BMI was inversely related to the risk of pulmonary edema. Conclusions: At least one PPC developed in almost half of the patients. Left-sided pleural effusion was the most common PPC, with hypoalbuminemia as a risk factor for effusion development. Atelectasis was the second most common. Bilateral effusion was the third most common PPC, significantly related to increased urine output. BMI was an independent risk factor for pulmonary edema development. Full article

Background: Cystectomy with urinary diversion (CUD) is a highly morbid surgery. Despite implementing an enhanced recovery after surgery (ERAS^®) protocol, postoperative respiratory complications (PRC) within 30 days after surgery remain frequent. This study aims to identify patients at higher risk of developing PRC after CUD. Methods: We conducted a retrospective analysis of 242 patients who underwent CUD at Lausanne University Hospital from 2012 to 2022, adhering to ERAS^® guidelines. Data on postoperative complications, including pneumonia, respiratory failure, pulmonary embolism, lobar atelectasis, and pleural effusion, were analyzed. Chi-square and Mann–Whitney U tests compared patients with and without PRC. A multivariable Cox model identified independent prognostic factors. Results: PRC occurred in 41 patients (17%). Those with PRC experienced longer hospital stays and higher 30-day mortality rates. Poor ERAS^® compliance was a significant risk factor. Multivariable analysis showed pneumonia was associated with postoperative ileus, while pulmonary embolism correlated with infectious and cardiovascular complications. Conclusions: PRC result in extended hospitalization and decreased survival. Rigorous adherence to ERAS^® protocols, including early mobilization, respiratory physiotherapy, and avoiding nasogastric tubes, is essential for preventing PRC. Full article
