Introduction: Postpneumonectomy empyema (PPE) is a severe and often fatal complication of pneumonectomy, but some benefits of PPE were reported in patients who underwent either lobe or an entire lung resection due to lung cancer., Aim: To compare the survival outcomes of patients with non-small-cell lung carcinoma (NSCLC), who developed PPE after pneumonectomy with uneventful recoveries available in our center's database., Material and Methods: Outcomes of 928 pneumonectomies performed due to NSCLC between 1995 and 2009 were evaluated. The selection of the control group took into account the requirements for propensity score matching in terms of follow-up period, age, sex, tumor histopathology, TNM classification and the side of surgery., Results: Thirty-two patients with a PPE syndrome and 96 patients without complications after pneumonectomy were included. The estimated 5- and 10-year survival rates were 71% and 59%, respectively. The average and median survival was almost two- and three-fold longer compared to the group with uneventful recoveries. A 2-fold lower cancer-related mortality rate and a 1.5-fold higher cancer-unrelated mortality rate were noted in the PPE group as opposed to the group without complications. Having recovered from PPE, the patients had their risk of death reduced by 2.5-fold and 3.5-fold due to all causes and cancer, respectively., Conclusions: Pleural empyema in NSCLC patients who underwent pneumonectomy seems to improve the survival outcomes compared to patients with uneventful recoveries., Competing Interests: The authors report no conflict of interest., (Copyright: © 2024 Polish Society of Cardiothoracic Surgeons (Polskie Towarzystwo KardioTorakochirurgów) and the editors of the Polish Journal of Cardio-Thoracic Surgery (Kardiochirurgia i Torakochirurgia Polska).)

Introduction: Near-infrared spectroscopy (NIRS) is a non-invasive method of regional tissue oxygenation measurement. Intraoperative use of NIRS to monitor brain oxygenation (BO) during surgery might be beneficial to identify cerebral desaturations., Aim: To compare peripheral blood saturation (SpO 2 ) with BO measurements and evaluate the utility of BO in thoracic surgery., Material and Methods: We took BO and SpO 2 measurements in a group of 100 patients undergoing standard thoracic surgery. Measurements were made every 15 minutes. The Mann-Whitney U test was used to compare study groups. Spearman's rank correlation coefficient was used to determine correlation between studied parameters., Results: We found a negative correlation between patients' age and BO at the beginning of surgery. Operations lasted between 30 and 200 minutes. We found a positive correlation between BO and SpO 2 between 15 and 90 minutes of surgery. Subsequently, BO remained at a low level while SpO 2 returned to baseline values. Higher minimum SpO 2 values were noted in patients undergoing left-sided procedures., Conclusions: Cerebral oxygenation does not return to baseline values until the end of the surgery as opposed to the SpO 2 . Furthermore, both SpO 2 and BO correlate negatively with the overall duration of thoracic surgery. In addition, after 90 minutes of surgery, SpO 2 stopped reflecting brain oxygenation., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2023 Polish Society of Cardiothoracic Surgeons (Polskie Towarzystwo KardioTorakochirurgów) and the editors of the Polish Journal of Cardio-Thoracic Surgery (Kardiochirurgia i Torakochirurgia Polska).)

Aim: The aim of this study was to compare the metabolic response in the early postoperative period after radical resection of stage I and II oesophageal cancer applying a minimally invasive procedure and an open procedure involving classical laparotomy and thoracotomy., Material and Methods: Serum concentrations of interleukin 6 (IL-6), procalcitonin (PCT), C-reactive protein (CRP), tumour necrosis factor-α (TNF-α), and total serum protein (TP) and leukocyte count (WBC) in blood collected on the day of surgery prior to the procedure (day 0) and on days 1, 2 and 7 after the surgery were measured in two groups of patients undergoing oesophageal resection due to cancer: applying a minimally invasive procedure involving laparoscopy and videothoracoscopy (group A) and applying a classical procedure involving full opening of the chest and abdominal cavity (group B). The study involved a total of 24 patients divided into two groups of 12 patients each., Results: Tumour necrosis factor-α concentration was lower in group A compared to group B on day 0, PCT concentration was lower in group A compared to group B on day 2 after surgery, and on the remaining days TNF-α and PCT concentrations were not statistically different between groups., Conclusions: Lower concentration of PCT on post-surgery day 2 in the group of patients undergoing minimally invasive oesophageal resection seems to be associated with a smaller perioperative injury. Lower TNF-α concentration in serum collected on day 0 in the group of patients undergoing minimally invasive resection is associated with a lower stage of oesophageal cancer in this group.

Background: Despite the progress in contemporary medicine comprising diagnostic and therapeutic methods, lung cancer is still one of the biggest health concerns in many countries of the world. The main purpose of the study was to evaluate the detection rate of pulmonary nodules and lung cancer in the initial, helical low-dose CT of the chest as well as the analysis of the relationship between the size and the histopathological character of the detected nodules., Material/methods: We retrospectively evaluated 1999 initial, consecutive results of the CT examinations performed within the framework of early lung cancer detection program initiated in Szczecin. The project enrolled persons of both sexes, aged 55-65 years, with at least 20 pack-years of cigarette smoking or current smokers. The analysis included assessment of the number of positive results and the evaluation of the detected nodules in relationship to their size. All of the nodules were classified into I of VI groups and subsequently compared with histopathological type of the neoplastic and nonneoplastic pulmonary lesions., Results: Pulmonary nodules were detected in 921 (46%) subjects. What is more, malignant lesions as well as lung cancer were significantly, more frequently discovered in the group of asymptomatic nodules of the largest dimension exceeding 15 mm., Conclusions: The initial, low-dose helical CT of the lungs performed in high risk individuals enables detection of appreciable number of indeterminate pulmonary nodules. In most of the asymptomatic patients with histopathologically proven pulmonary nodules greater than 15 mm, the mentioned lesions are malignant, what warrants further, intensified diagnostics.
