Pulmonary Sequestration: A Monocentric Case Series Report.

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.

A structured curriculum for the acquisition of basic surgical endoscopic skills for surgical residents and quantification of skills improvement.

Introduction: New strategies and methods are needed to ensure that new generations can train and acquire surgical skills in a safe environment. Materials and methods: From January 2020 to October 2020, we performed a single centre, prospective observational cohort study. 19 participants (15 students, 4 residents) enrolled and 16 participants (13 students, 3 residents) successfully completed the curriculum. We performed a quantitative data analysis to evaluate its effectiveness in gaining and improving basic surgical endoscopic skills. Results: The time for single knot tying pre-, mid-, and post-training was reduced significantly, the average time (sec) decreased by 79.5 % (p < 0.001), the total linear distance (cm) by 74.5 % (p < 0.001) and the total angular distance (rad) by 71.7 % (p < 0.001). The average acceleration (mm/s2) increased by 20 % (p = 0.041). Additionally, the average speed increased by 23.5 % (p < 0.001), while motion smoothness (m/s3) increased by 20.4 % (p = 0.02). Conclusion: The obtained performance scores showed a significant increase in participants improving their basic surgical performance skills on the endoscopic simulator. This curriculum can be easily implemented in any surgical specialty as part of the residency training curriculum before first exposure in the operation room. All 16 participants recommended the implementation of such simulator training in their surgical training curriculum.

Urban thoracic trauma: diagnosis and initial treatment of non-cardiac injuries in adults.

This comprehensive review aims to delineate the prevailing non-cardiac thoracic injuries occurring in urban environments following initial on-site treatment and subsequent admission to hospital emergency departments. Our study involved a rigorous search within the PubMed database, employing key phrases and their combinations, including "thoracic injury," "thoracic trauma," "haemothorax," "lung contusion," "traumatic pneumothorax," "rib fractures," and "flail chest." We focused on original research articles and reviews. Non-cardiac thoracic injuries exhibit a high prevalence, often affecting poly-trauma patients, and contributing to up to 35% of polytrauma-related fatalities. Furthermore, severe thoracic injuries can result in a substantial 5% mortality rate. This review provides insights into clinical entities such as lung contusion, traumatic haemothorax, pneumothorax, rib fractures, and sternal fractures. Thoracic injuries represent a frequent and significant clinical concern for emergency department physicians and thoracic surgeons, warranting thorough understanding and timely intervention.

Challenges and pitfalls in the perioperative management of mediastinal mass syndrome: an up-to-date review.

The perioperative management of patients undergoing mediastinal mass operations presents a persistent challenge across multiple clinical specialties. General anesthesia administration further increases the risk of perioperative cardiorespiratory decompensation. The interdisciplinary team plays a crucial role in ensuring a safe perioperative period. However, due to the rarity and variability of mediastinal mass syndromes, specific management protocols are lacking. This review aims to outline the multitude of challenges and pitfalls encountered during perioperative management in patients with the mediastinal mass syndrome. We describe diagnostic evaluation, preoperative optimization, intraoperative considerations, and postoperative care strategies, emphasizing the paramount significance of a multidisciplinary approach and personalized treatment plans. Preoperative multidisciplinary discussions, meticulous anesthetic management, and well-established protocols for emergency situations are pivotal to ensuring patient safety. Healthcare providers involved in the care of patients with mediastinal mass syndrome must grasp these challenges and pitfalls, enabling them to deliver safe and effective perioperative management.

Are Extensive Open Lung Resections for Elderly Patients with Lung Cancer Justified?

BACKGROUND: Older patients with malignancies are more comorbid than younger ones and are usually undertreated only because of their age. The aim of this study is to investigate the safety of open anatomical lung resections for lung cancer in elderly patients. METHODS: We retrospectively analyzed all patients who underwent lung resection for lung cancer in our institution and categorized them into two groups: the elderly group (≥70 years old) and the control (<70). RESULTS: In total, 135 patients were included in the elderly group and 375 in the control. Elderly patients were more frequently diagnosed with squamous cell carcinoma (59.3% vs. 51.5%, p = 0.037), higher differentiated tumors (12.6% vs. 6.4%, p = 0.014), and at an earlier stage (stage I: 55.6% for elderly vs. 36.6%, p = 0.002). Elderly patients were more vulnerable to postoperative pneumonia (3.7% vs. 0.8%, p = 0.034), lung atelectasis (7.4% vs. 2.9%, p = 0.040), and pleural empyema (3.2% vs. 0%, p = 0.042), however, with no increased 30-day-mortality (5.2% for elderly vs. 2.7%, p = 0.168). Survival was comparable in both groups (43.4 vs. 45.3 months, p = 0.579). CONCLUSIONS: Elderly patients should not be excluded from open major lung resections as the survival benefit is not reduced in selected patients.

Perioperative Application of Levosimendan Optimizes Postoperative Renal Function and Organ Perfusion in Patients with Severe Heart Failure.

Background: Renal dysfunction and impaired organ perfusion are common concerns following cardiac surgery. Levosimendan, a calcium sensitizer inotropic drug, is investigated in this study for its potential to improve postoperative renal function and organ perfusion in patients with low preoperative ejection fraction and severe myocardial dysfunction after cardiac surgery. Methods: A retrospective analysis was conducted on 314 patients with preoperative heart failure who underwent cardiac surgery. Among them, 184 patients received perioperative adjunctive therapy with levosimendan, while 130 patients with similar characteristics received conventional treatment. Results: The perioperative administration of levosimendan resulted in a significantly lower need for renal replacement therapy (p < 0.001) and improvements in the serum creatinine levels, glomerular filtration rate, and creatinine clearance. Similarly, the C-reactive protein levels, blood pH, and lactic acid levels showed comparable improvements. Conclusions: The use of levosimendan was associated with a significant enhancement in postoperative renal function and a reduction in the need for renal replacement therapy. Furthermore, it resulted in a decrease in the extent of organ malperfusion. Postoperative inflammatory reactions and metabolic balance also exhibited improvements.

The Perioperative Use of Levosimendan as a Means of Optimizing the Surgical Outcome in Patients with Severe Heart Insufficiency Undergoing Cardiac Surgery.

BACKGROUND: Postoperative myocardial dysfunction following cardiac surgery is a relatively common occurrence. Levosimendan, a calcium sensitizer and inotropic drug, has shown potential in improving outcomes for patients with low preoperative ejection fraction (EF) and myocardial dysfunction after cardiac surgery. This study aims to evaluate the efficacy of levosimendan in optimizing the surgical outcome for such patients. METHODS: A retrospective analysis was conducted on 314 patients with preoperative severe heart failure who underwent cardiac surgery. Among them, 184 patients received perioperative adjunctive therapy with levosimendan, while a comparable group of 130 patients received conventional treatment. RESULTS: The use of levosimendan demonstrated several advantages in postoperative outcomes. It significantly improved short- and long-term survival rates after cardiac surgery, enhanced hemodynamic stability, reduced the requirement for inotropic support, and facilitated faster weaning from ventilator support. Patients who received levosimendan reported reduced angina and dyspnea symptoms, as well as fewer postoperative arrhythmias. Furthermore, levosimendan helped minimize myocardial injury inevitable after cardiac surgery. The levosimendan group also exhibited a notable reduction in hospital readmissions. CONCLUSIONS: This study provides evidence of several benefits associated with the perioperative use of levosimendan. However, further prospective randomized studies are warranted to standardize and comprehensively document the other perioperative therapies, in order to validate these findings and establish stronger conclusions.

Segmentectomy versus lobectomy. Which factors are decisive for an optimal oncological outcome?

Low-dose computed tomography is being used for lung cancer screening in high-risk groups. Detecting lung cancer at an early stage improves the chance of optimal treatment and increases overall survival. This article compares segmentectomy vs. lobectomy as surgical options, in the case of stage I non-small cell lung carcinoma, ideally IA. To compare the 2 previously referred strategies, data were collected from articles (40 studies were reviewed), reviews, and systematic analyses in PubMed Central, as well as reviewing recent literature. Segmentectomy could be an equal alternative to lobectomy in early-stage NSCLC (tumour < 2 cm). It could be preferred for patients with a low cardiopulmonary reserve, who struggle to survive a lobectomy. As far as early-stage NSCLC is concerned, anatomic segmentectomy is an acceptable procedure in a selective group of patients. For better tumour and stage classification, a systematic lymph node dissection should be performed.

Impelling Factors for Contracting COVID-19 Among Surgical Professionals During the Pandemic: A Multinational Cohort Study.

Background: Medical workers, including surgical professionals working in coronavirus disease 2019 (COVID-19) treating hospitals, were under enormous stress during the pandemic. This global study investigated factors endowing COVID-19 amongst surgical professionals and students. Methods: This global cross-sectional survey was made live on February 18, 2021 and closed for analysis on March 13, 2021. It was freely shared on social and scientific media platforms and was sent via email groups and circulated through a personal network of authors. Chi-square test for independence, and binary logistic regression analysis were carried out on determining predictors of surgical professionals contracting COVID-19. Results: This survey captured the response of 520 surgical professionals from 66 countries. Of the professionals, 92.5% (481/520) reported practising in hospitals managing COVID-19 patients. More than one-fourth (25.6%) of the respondents (133/520) reported suffering from COVID-19 which was more frequent in surgical professionals practising in public sector healthcare institutions (P = 0.001). Thirty-seven percent of those who reported never contracting COVID-19 (139/376) reported being still asked to practice self-isolation and wear a shield without the diagnosis (P = 0.001). Of those who did not contract COVID-19, 75.7% (283/376) were vaccinated (P < 0.001). Surgical professionals undergoing practice in the private sector (odds ratio (OR): 0.33; 95% confidence interval (CI): 0.14 - 0.77; P = 0.011) and receiving two doses of vaccine (OR: 0.55; 95% CI: 0.32 - 0.95; P = 0.031) were identified to enjoy decreased odds of contracting COVID-19. Only 6.9% of those who reported not contracting COVID-19 (26/376) were calculated to have the highest "overall composite level of harm" score (P < 0.001). Conclusions: High prevalence of respondents got COVID-19, which was more frequent in participants working in public sector hospitals. Those who reported contracting COVID-19 were calculated to have the highest level of harm score. Self-isolation or shield, getting two doses of vaccines decreases the odds of contracting COVID-19.

Lung Metastatectomy: Can Laser-Assisted Surgery Make a Difference?

BACKGROUND: Resection of lung metastases with curative intention in selected patients is associated with prolonged survival. Laser-assisted resection of lung metastases results in complete resection of a high number of lung metastases, while preserving lung parenchyma. However, data concerning laser lung resections are scarce and contradictory. The aim of this study was to conduct a systematic review to evaluate the utility of laser-assisted pulmonary metastasectomy. METHODS: An electronic search in MEDLINE (via PubMed), complemented by manual searches in article references, was conducted to identify eligible studies. RESULTS: Fourteen studies with a total of 1196 patients were included in this metanalysis. Laser-assisted surgery (LAS) for lung metastases is a safe procedure with a postoperative morbidity up to 24.2% and almost zero mortality. LAS resulted in the resection of a high number of lung metastases with reduction of the lung parenchyma loss in comparison with conventional resection methods. Survival was similar between LAS and conventional resections. CONCLUSION: LAS allows radical lung-parenchyma saving resection of a high number of lung metastases with similar survival to conventional methods.

Subtyping non-small cell lung cancer by histology-guided spatial metabolomics.

PURPOSE: Most cancer-related deaths worldwide are associated with lung cancer. Subtyping of non-small cell lung cancer (NSCLC) into adenocarcinoma (AC) and squamous cell carcinoma (SqCC) is of importance, as therapy regimes differ. However, conventional staining and immunohistochemistry have their limitations. Therefore, a spatial metabolomics approach was aimed to detect differences between subtypes and to discriminate tumor and stroma regions in tissues. METHODS: Fresh-frozen NSCLC tissues (n = 35) were analyzed by matrix-assisted laser desorption/ionization-mass spectrometry imaging (MALDI-MSI) of small molecules (< m/z 1000). Measured samples were subsequently stained and histopathologically examined. A differentiation of subtypes and a discrimination of tumor and stroma regions was performed by receiver operating characteristic analysis and machine learning algorithms. RESULTS: Histology-guided spatial metabolomics revealed differences between AC and SqCC and between NSCLC tumor and tumor microenvironment. A diagnostic ability of 0.95 was achieved for the discrimination of AC and SqCC. Metabolomic contrast to the tumor microenvironment was revealed with an area under the curve of 0.96 due to differences in phospholipid profile. Furthermore, the detection of NSCLC with rarely arising mutations of the isocitrate dehydrogenase (IDH) gene was demonstrated through 45 times enhanced oncometabolite levels. CONCLUSION: MALDI-MSI of small molecules can contribute to NSCLC subtyping. Measurements can be performed intraoperatively on a single tissue section to support currently available approaches. Moreover, the technique can be beneficial in screening of IDH-mutants for the characterization of these seldom cases promoting the development of treatment strategies.

The global level of harm among surgical professionals during the COVID-19 pandemic: A multinational cross-sectional cohort study.

BACKGROUND: Health care workers, including surgical professionals, experienced psychological burnout and physical harm during the coronavirus 2019 pandemic. This global survey investigated the coronavirus 2019 pandemic impact on psychological and physical health. METHODS: We conducted a global cross-sectional survey between February 18, 2021 and March 13, 2021. The primary outcome was to assess the psychological burnout, fulfillment, and self-reported physical level of harm. A validated Stanford Professional Fulfilment Index score with a self-reported physical level of harm was employed. We used a practical overall composite level of harm score to calculate the level of harm gradient 1-4, combining psychological burnout with self-reported physical level of harm score. RESULTS: A total of 545 participants from 66 countries participated. The final analysis included 520 (95.4%) surgical professionals barring medical students. Most of the participants (81.3%) were professionally unfulfilled. The psychological burnout was evident in 57.7% and was significantly common in those <50 years (P = .002) and those working in the public sector (P = .005). Approximately 41.7% of respondents showed changes in the physical health with self-remedy and no impact on work, whereas 14.9% reported changes to their physical health with <2 weeks off work, and 10.1% reported changes in physical health requiring >2 weeks off work. Severe harm (level of harm 4) was detected in 10.6%, whereas moderate harm (level of harm 3) affected 40.2% of the participants. Low and no harm (level of harm 2 and level of harm 1) represented 27.5% and 21.7%, respectively. CONCLUSION: Our study showed that high levels of psychological burnout, professional unfulfillment, work exhaustion, and severe level of harm was more frequent in younger professionals working in the public sector. The findings correlated with a high level of harm in surgical professionals impacting surgical services.
