RESUMO
INTRODUCTION: Lung cancer is a serious health problem with a high mortality rate. In the context of surgical management, minimally invasive approaches, including uniportal thoracoscopic techniques, offer potential benefits such as faster recovery and increased patient cooperation. The aim of this study was to compare the accessibility of the mediastinal lymph nodes between uniportal and multiportal thoracoscopic approaches and to verify whether the use of the uniportal approach affects the radicality of the lymphadenectomy. METHODS: A comparative study conducted from January 2015 to July 2022 at the University Hospital Ostrava focused on evaluating the radicality of mediastinal lymphadenectomy between subgroups of patients undergoing surgery using the uniportal thoracoscopic approach and the multiportal thoracoscopic approach. RESULTS: A total of 278 patients were included in the study. There were no significant differences in the number of available lymphatic stations between the subgroups. The mean number of lymph node stations removed was 6.46 in the left hemithorax and 6.50 in the right hemithorax. Thirty-day postoperative morbidity for the entire patient population was 24.5%, with 18.3% having minor complications and 3.6% having major complications. The overall mortality rate in the study population was 2.5%, with a statistically significant difference in mortality between uniportal and multiportal approaches (1.0% vs 6.4%, p=0.020). CONCLUSIONS: The uniportal approach demonstrated comparable accessibility and lymph node yield to the multiportal approach. There was also no difference in postoperative morbidity between the two approaches. The study suggests the possibility of lower mortality after uniportal lung resection compared with multiportal lung resection, but this conclusion should be interpreted with caution.

INTRODUCTION: Lung cancer is the most common cause of cancer death in the Czech Republic, in part due to its significant metastatic potential. The aim of this study was to collect real data on the metastatic potential and clinical characteristics of T1a and T1b lung cancer in the Czech population and to investigate potential factors that would predict an increased risk of lymph node metastasis. METHODS: Prospective-retrospective study conducted at the Department of Surgery of the University Hospital Ostrava during the period from January 1, 2015, to July 31, 2022. The study included patients who underwent lobectomy or bilobectomy for T1a and T1b non-small cell lung carcinoma. RESULTS: Out of a total of 165 patients with T1a and T1b lung carcinoma, 17.6% of patients were confirmed to have metastatic involvement of the lymph nodes (with 9.1% classified as N2 lymph node involvement). The highest percentage of positive lymph nodes was observed in patients with tumors located in the upper left lobe (29.5%) and lower right lobe (23.3%). Adenocarcinoma was the most commonly metastasizing carcinoma, with 21.1% of patients showing positive lymph nodes. Neuroendocrine carcinoma metastasized in 19.4% of cases, while squamous cell carcinoma did so in 6.8% of cases. The cumulative risk of having positive lymph nodes in T1a and T1b adenocarcinoma located in the upper left lobe reached 40.0%, of which the risk of N2 lymph node involvement was 25.0%. CONCLUSION: T1a/b non-small cell lung cancer exhibits significantly lower metastatic potential than T1c tumors and higher. Adenocarcinoma showed a 3-fold higher metastatic potential than squamous cell carcinoma, indicating the need for increased attention in the treatment of lung adenocarcinoma, especially in tumors localized in the upper left lobe, where a cumulative risk of lymph node metastasis of up to 40% was observed.

The retrotracheal form is a rare variant of retrosternal goitre. The incidence is low, representing approximately 4% of all retrosternal goitres. The traditional approach to the treatment of this type of pathology is the cervical approach combined with high thoracotomy. Recently, however, new methods and technologies have begun to emerge that also open new possibilities for the surgical management of these conditions. The aim of this case report was to present the potential of a video-robotic approach in the treatment of retrotracheal goitre. The authors have successfully used this innovative method in the treatment of retrotracheal lesions, bringing hope for more effective and less invasive surgical interventions in this difficult-to-access area.
