RESUMO

OBJECTIVES: Mediastinal neoplasms are typical but uncommon thoracic diseases with increasing incidence and unfavorable prognoses. A comprehensive understanding of their spatiotemporal distribution is essential for accurate diagnosis and timely treatment. However, previous studies are limited in scale and data coverage. Therefore, this study aims to elucidate the distribution of mediastinal lesions, offering valuable insights into this disease. MATERIALS AND METHODS: This multi-center, hospital-based observational study included 20 nationwide institutions. A retrospective search of electronic medical records from January 1st, 2009, to December 31st, 2020, was conducted, collecting sociodemographic data, computed tomography images, and pathologic diagnoses. Analysis focused on age, sex, time, location, and geographical region. Comparative assessments were made with global data from a multi-center database. RESULTS: Among 7,765 cases, thymomas (30.7%), benign mediastinal cysts (23.4%), and neurogenic tumors (10.0%) were predominant. Distribution varied across mediastinal compartments, with thymomas (39.6%), benign cysts (28.1%), and neurogenic tumors (51.9%) most prevalent in the prevascular, visceral, and paravertebral mediastinum, respectively. Age-specific variations were notable, with germ cell tumors prominent in patients under 18 and aged 18-29, while thymomas were more common in patients over 30. The composition of mediastinal lesions across different regions of China remained relatively consistent, but it differs from that of the global population. CONCLUSION: This study revealed significant heterogeneity in the spatiotemporal distribution of mediastinal neoplasms. These findings provide useful demographic data when considering the differential diagnosis of mediastinal lesions, and would be beneficial for tailoring disease prevention and control strategies.

RESUMO

Background: Various methods exist for locating lung nodules, each with its own advantages and disadvantages. Aiming to find a more accurate, safe, effective, economical and practical method for locating lung nodules, this study evaluated the safety and feasibility of a precise three-dimensional (3D) method for positioning small pulmonary nodules based on anatomical landmarks. Methods: From June 2019 to December 2021, 120 patients with 131 pulmonary nodules who underwent video-assisted thoracoscopic surgery at the University of Hong Kong-Shenzhen Hospital were included in the study. Surgical data such as the positioning time, accuracy rate, pathological result, localization-related complication rate and length of postoperative hospital stay were retrospectively reviewed and analyzed. During surgery, pulmonary nodules were accurately located by the 3D positioning method based on anatomical landmarks and then removed to determine the pathology. Results: A total of 120 patients, including 35 males and 85 females, were included, and the median age was 53 years [interquartile range (IQR), 41-63 years]. No mortality or major morbidity occurred within 30 days. The median localization time was 11 minutes (IQR, 8-14 minutes). The accuracy of localization was 98.5%. The median diameter of the pulmonary nodules was 8 mm (IQR, 7-13 mm), and the median distance from the visceral pleura was 6 mm (IQR, 2-10 mm). No location-related complications occurred. The median length of postoperative hospital stay was 5 days (IQR, 3-7 days). Conclusions: The proposed positioning method is accurate, safe and feasible for selected patients with pulmonary nodules. Compared with other preoperative and intraoperative positioning methods, it can significantly reduce localization-related complications.

RESUMO

BACKGROUND: To assess the feasibility and safety of tubeless video-assisted thoracoscopic sympathectomy (VATS) with a single 5 mm port under nonintubated, intravenous anesthesia with spontaneous ventilation in selected patients with primary palmar hyperhidrosis (PPH). METHODS: Adults (aged between 18 and 60 years) with moderate or severe PPH symptoms were enrolled. Demographic information and clinical data were obtained from 172 consecutive patients undergoing thoracoscopic surgery for PPH from March 2014 to December 2020. The primary outcomes were the rate of complications, including death, and the intraoperative conversion rate to 3-port VATS. The secondary outcomes were the conversion rate to intubated anesthesia during the operation and the surgical duration and pain score of postoperative day 0. RESULTS: In total, 172 patients were included with 88 males and 84 females. The median age was was 25 years (IQR:21-30 years). No mortalities or major morbidities occurred in any patient. The overall median surgical duration was 53 min (IQR:37-72 min). The median length of postoperative hospital stay was one day (IQR:one-one day). The median pain score of POD0 was 2 (IQR:2-2). Intraoperative conversion to 3-port VATS followed by drainage tube insertion occurred in one (0.6%) patient due to extensive pleural adhesions. No patients required conversion to intubated anesthesia during surgery. No postoperative mechanical ventilation was noted in any patient. CONCLUSIONS: For selected patients with PPH, tubeless VATS with a single 5 mm port using spontaneous ventilation anesthesia can be considered a feasible and safe operation. The surgical wound is extremely small and the operation time is shorter than the conventional technique. Trial registration This study was in conformity with the Declaration of Helsinki, and was approved by the National Ethics Committee of the University of the Hong Kong-Shenzhen Hospital (Approval number: [2020]70).

RESUMO

BACKGROUND: Using a minimum dose of neuromuscular blockade (NMB) to achieve intubation condition is one of the goals in anaesthesia management of patients with myasthenia gravis (MG) for thoracoscopic (VATS) thymectomy. However, tracheal intubation with double lumen tube (DLT) could be challenging if intubation condition is not optimal. This double-blind randomised controlled study was designed to investigate whether magnesium sulfate would reduce the rocuronium dose needed for DLT intubation and improve the DLT placement condition for patients with MG who were scheduled for video-assisted thoracoscopic (VATS) thymectomy. METHODS: Recruited patients were randomly assigned to receive magnesium sulfate 60 mg.kg- 1 or normal saline (control) prior to the administration of NMB. Titrating dose of rocuronium was administered to achieve train of four (TOF) ratio less than 10% before DLT intubation. The primary outcome was the rocuronium dose required to achieve TOF ratio less than 10%. The secondary outcome was intubation condition for DLT placement. RESULTS: Twenty-three patients had received magnesium sulfate and 22 patients had received normal saline before rocuronium administration. The required rocuronium dose [mean (standard deviation)] were 0.10 (0.05) mg.kg- 1 and 0.28(0.17) mg.kg- 1 in patients who had magnesium sulfate and normal saline respectively(P < 0.0001). With a similar depth of neuromuscular blockade and depth of anaesthesia, 100% of patients in the magnesium sulfate group and 72.7% of patients in the control group showed excellent intubation condition (P = 0.027) respectively. The patients in both groups had similar emergence characteristics. CONCLUSIONS: Magnesium sulfate is associated with a decrease in rocuronium requirement for an optimal DLT intubation condition in patients with MG for VATS thymectomy.

RESUMO

BACKGROUND: Pulmonary sequestration is an uncommon congenital condition for which surgical resection is usually indicated - either via open thoracotomy or conventional multi-port Video-Assisted Thoracoscopic Surgery (VATS). Of the two types of sequestration, intralobar sequestration is technically more challenging to resect. CASE PRESENTATION: We report the management of a 34 year old male patient with a long history of respiratory symptoms, and an extensively diseased right lower lobe. A diagnosis of sequestration was confirmed by CT scanning, showing three separate anomalous feeding vessels arising from the abdominal aorta. A right lower lobectomy using a Uniportal VATS approach was performed, and the patient discharged home on the fourth post-operative day. CONCLUSION: This is the first report to our knowledge demonstrating the safety and feasibility of the Uniportal approach for the resection of a relatively challenging intralobar sequestration.

RESUMO

OBJECTIVE: The staging and treatment of bronchioloalveolar carcinoma (BAC) with pulmonary metastasis are still controversial. This study aimed at evaluating the current staging of BAC with ipsilateral intrapulmonary metastatic nodules and the therapeutic effectiveness of surgical resection. METHODS: The clinicopathological data of 729 completely and surgically resected patients with non-small cell lung cancer (NSCLC) from December 1999 to December 2006 were retrospectively reviewed. Prognostic factors affecting the overall survival were analyzed by the Kaplan-Meier method and compared by the log rank test. RESULTS: Among 67 NSCLC patients with ipsilateral intrapulmonary metastatic nodules, 54 had multiple nodules in the lobe with primary lesion (T4, PM1) and 13 had additional nodules in the other ipsilateral lobes (M1, PM2). This series consisted of 40 males and 27 females, with a median age of 60.0 years. Of those, 28 had the lesions containing pure or some bronchioloalveolar carcinoma component, while the other 39 had a NSCLC lesions containing non-bronchioloalveolar carcinoma components. The median overall survival time of this series was 24.0 months. Prognostic study demonstrated that bronchioloalveolar carcinoma histology and mediastinal lymph node metastasis had significant adverse impact on the overall survival. The median survival time of the patients with bronchioloalveolar carcinoma was 58.0 months versus 27.0 months in patients with other subtypes of NSCLC (P < 0.01). The median survival times were 39.0 months for the patients with N0 or N1 versus 14.0 months for patients with N2, with a significant difference between the two groups (P < 0.01). There was no significant difference in the survival time between the patients with PM1 (36 months) and those with PM2 (24 months) (P > 0.05). CONCLUSION: Surgical resection is effective for NSCLC patients with ipsilateral intra-pulmonary metastasis, especially for those with bronchioloalveolar carcinoma components. Our results suggest that the current TNM classification system may be inappropriate for the NSCLC patients with ipsilateral intrapulmonary metastatic nodules, and may need a modification.

RESUMO

OBJECTIVES: The staging and treatment of multi-focal non-small cell lung cancer (NSCLC) are controversial. This study evaluated the effectiveness of surgical treatment for the ipsilateral multi-focal NSCLC. METHODS: Sixty-eight patients with multi-focal NSCLC underwent complete resection from December 1999 to December 2006. This series included 44 males and 24 females, with a mean age of 60.3 years old (range from 33 to 81 years old). Fifty-four patients had multiple nodules in primary lobe (T4) and 13 patients had additional nodules in non-primary lobe (M1), and a patient was proved to have synchronous primary NSCLC lesions. Surgical treatments included lobectomy in 53 cases, bilobectomy in 4 cases, pneumonectomy in 2 cases, and lobectomy combined with wedge resection in 9 cases. RESULTS: The median overall survival time of this series was 30 months. Prognostic study demonstrated that mediastinal lymph node metastasis and bronchioloalveolar carcinoma histology had significant impact on overall survival. The median survival times were 39 months for patients with N0 and N1, and 14 months for patients with N2, respectively, and there was significant difference between the groups (P < 0.01). The difference in survival was significant between patients with bronchioloalveolar carcinoma components and other NSCLC histologic types (P < 0.01), and the median survival times were 46 months and 20 months, respectively. CONCLUSION: Surgery could provide choice for multi-focal NSCLC patients (T4 and M1), especially for patients with bronchioloalveolar carcinoma components and without mediastinal lymph node metastasis.
