Elderly patients with lung cancer have a significantly increased risk of perioperative cardiopulmonary complications due to physiological decline, high incidence of complications and reduced surgical tolerance, which directly affects postoperative recovery and long-term survival. Although the concepts of minimally invasive surgery and enhanced recovery after surgery have improved clinical outcomes, early recognition and intervention of postoperative complications in elderly patients remains a significant challenge in the field of thoracic surgery. By integrating recent literature and clinical practice, this paper systematically analyzes the pathophysiological mechanism and risk factors of perioperative cardiopulmonary complications in elderly patients with lung cancer, and discusses individualized intervention strategies based on risk stratification and multidisciplinary team, in order to provide theoretical basis and practical guidance for optimizing perioperative management and improving postoperative prognosis in elderly patients.

Objective:To evaluate the impact of the surgical strategy of selective thoracic duct(TD) ligation established through fluorescence thoracoscopy TD imaging technology on the occurrence of chylothorax after lung cancer surgery in the elderly.Methods:A prospective cohort study was conducted.Elderly patients who underwent right lung cancer surgery in the Department of Thoracic Surgery of Beijing Hospital from October 2023 to June 2024 were enrolled as the research subjects.The surgical approaches involved pulmonary resection, systematic lymphadenectomy, and selective TD ligation using fluorescence thoracoscopy.Prior to the surgery, 0.4 mg/kg indocyanine green(ICG)was injected subcutaneously into the right inguinal region of all patients.Clinical data, surgical details, pathological information, and intraoperative TD imaging, including the course, collateral vessels, and any injuries, were collected.Postoperative chylothorax and other complications were also recorded.Results:A total of 83 patients were enrolled, of which 38 were males, and 45 were females, with a median age of 68 years raging from 60 to 83 years old, TD imaging was observed in 69 cases(83.1%)within one hour after IGC injection.Intraoperative injuries of collateral branches were visualized in 4 cases(4.8%). Among them, 2 cases had injuries in both the 2R+ 4R and the subcarinal station, while 2 others had injuries of collateral branches only in the 2R+ 4R station.These 4 patients underwent concurrent TD ligation.No TD or collateral injury was found in the remaining patients during the surgery, and the TD was not ligated, none of the patients developed chylothorax postoperatively, and no adverse reactions related to indocyanine green were observed.Conclusions:Fluorescence thoracoscopy-guided TD imaging technique can well visualize TD and its collateral injuries in elderly lung cancer surgeries, assist in the management of leaks or TD ligation, thereby effectively preventing the occurrence of postoperative chylothorax.

The widespread adoption of low-dose chest CT has facilitated earlier detection and treatment of lung cancer. Conventional surgery remains the primary treatment modality with the most definitive efficacy. However, the rapidly growing number of patients with early-stage lung nodules presents a new challenge in managing those with multiple primary lung nodules (MPLN). Extensive surgical resection of multiple nodules, which can lead to significant pulmonary function loss, demands high cardiopulmonary reserve, and carries a substantial risk of complications, is often not suitable for patients with advanced age, poor general condition, or challenging nodule locations. This article reviews the primary surgical modalities for multiple pulmonary nodules, discussing their respective advantages and disadvantages. It also presents our center′s experience with a hybrid approach that integrates conventional surgery and radiofrequency ablation, aiming to minimize perioperative risks while preserving long-term oncological outcomes.

Objective To evaluate the perioperative safety of lung surgery for patients with corona virus disease 2019 (COVID-19). Methods We retrospectively analyzed the clinical data of the patients recovered from COVID-19 infection and received lung surgery from December 2022 to February 2023 in the Department of Thoracic Surgery at Beijing Hospital. Patients who received lung surgery and without COVID-19 at the same time were selected as a control group. Perioperative data between the two groups were compared. Results A total of 103 patients were included with 44 males and 49 females at an average age of (62.2±12.1) years. All surgeries were performed by uniportal video-assisted thoracoscopic surgery (VATS). Among patients who recovered from COVID-19, 53 (51.5%) received lobectomy, 30 (29.1%) received segmentectomy, and 20 (19.4%) received wedge resection. The interval between diagnosis of infection and lung surgery was ≤1 month in 32 (31.1%) patients, and >1 month in 71 (68.9%) patients. The results of virus nucleic acid test for all patients before surgery were negative. A total of 13 (12.6%) patients had positive IgM, and 100 (97.1%) patients had positive IgG. A total of 20 patients experienced perioperative complications (13 patients with pulmonary air leakage, 3 patients with chylothorax, 2 patients with atrial fibrillation, and 2 patients with severe pulmonary complications). There was one perioperative death. Comparing the patients who recovered from COVID-19 with those without COVID-19, we found no statistical difference in perioperative outcomes including surgical duration, postoperative drainage, duration of thoracic tube, and duration of postoperative stay (P>0.05). There was no significant difference in perioperative complications between the two groups (P>0.05). Multivariable logistical regression analysis demonstrated that positive IgM before surgery (OR=7.319, 95%CI 1.669 to 32.103, P=0.008), and longer duration of surgery (OR=1.016, 95%CI 1.003 to 1.028, P=0.013) were independent risk factors of perioperative complications for patients who recovered from COVID-19. Conclusion It is safe for patients recover from COVID-19 to receive lung surgery when symptoms disappear and the nucleic acid test turn negative. However, positive COVID-19 IgM is an independent risk factor for perioperative complications. We suggest that lung surgery could be performed when the nucleic acid test and COVID-19 IgM are both negative for patients recover from COVID-19 infection.

Objective:To evaluate the safety of thymic surgery in patients aged 65 years and over.Methods:A total of 696 patients who underwent thymectomy/thymoma resection in the Department of Thoracic Surgery of Beijing Hospital from November 2011 to March 2022 were collected and divided into two groups according to the age of 65 years old.The preoperative course of disease, MG stage, dosage of pyridostigmine bromide, American College of Anesthesiologists(ASA)score, surgical method, intraoperative bleeding, postoperative drainage, postoperative complications, Clavien-dindo score(CDC), and myasthenic crisis were recorded and statistically analyzed.Results:A total of 696 patients were enrolled, including 364 males and 332 females, aged 15~86 years, with an average age of 49.1 years.There were 309 patients with thymoma, 565 patients with MG, and 178 patients with both.There were 124 cases in the elderly group(≥65 years old)and 572 cases in the non-elderly group(<65 years old). The incidence of thymoma was higher in the elderly group(54.8 % versus 42.1 %, χ2=6.664, P=0.010), while the incidence of MG was lower(67.7 % versus 84.1 %, χ2=17.827, P<0.001). The ASA score of the elderly group was higher than that of the non-elderly group( χ2=52.372, P=0.000), and the preoperative ventilation function FEV1 and FEV1/FVC were also significantly lower than those of the non-elderly group( z=8.187, 4.580, P=0.000 for all). The drainage volume in the first 3 days after operation and postoperative drainage tube time in the elderly group were significantly higher than those in the non-elderly group( P=0.018, P=0.003). The incidence of postoperative myasthenia crisis in the elderly group was higher than that in the non-elderly group( P=0.034). There was no significant difference in the incidence of postoperative complications between the two groups, but after Clavien-dindo classification, the score of the elderly group was higher than that of the non-elderly group( P=0.003). Although the ASA score and Clavien-dindo score of the elderly group were both higher than those of the non-elderly group, there was no correlation between the two. Conclusions:Although the preoperative ASA score and pulmonary function of elderly patients were poorer than those in the non-elderly group, while the incidence of postoperative myasthenia crisis was higher, and the incidence of postoperative complications was not higher, the Clavien-dindo classification, however, was higher in elderly patients than that of the non-elderly group.After careful preoperative evaluation and strengthening perioperative management, most elderly patients can receive thymus surgery safely with acceptable risks.

Objective:To evaluate the clinical characteristics and the surgical safety in patients aged 65 years and over with thymic epithelial tumor, and analyze the prognosis of 3-10 years postoperative tumor and myasthenia gravy.Methods:A total of 228 patients diagnosed as thymic tumor and undergoing surgical surgery to remove the tumor in Beijing Hospital from Jan.2011 to Dec.2018 were retrospectively enrolled.Patients were divided into a young(≤ 65 yrs)and old(>65 yrs)groups.The operation time, intra-operative bleeding, drainage volume in the first 3 days after operation, days with drainage tube after operation, postoperative days of hospital stays, the diameter of the tumors, pathological classification, Tumor-Node-Metastasis(TNM)staging, Masaoka-Koga staging, whether or not complicated with myasthenia gravis and complications were compared between two groups.The patients were followed up by outpatient or telephone, and recurrence of thymoma, survival status and improvement of myasthenia gravis were tracked.Results:There were significant differences in pathological classification between the two groups( P=0.002). The postoperative days with drainage tube were longer in patients≥65 years old than in patients<65 years old[4(2-17)days and 3(1-9), Z=2.316, P=0.021]. Thymic atrophy was more common in patients ≥ 65 years old than in patients <65 years old(10.2% and 1.7%, χ2=5.937, P=0.015). Incidence of thymoma plus myasthenia gravis were higher in patients aged <65 years than those aged ≥65years(68.2% vs.40.8%, χ2=12.240, P<0.001), and incidence of thymic hyperplasia were higher in patients aged <65 years than those aged ≥65years(58.1% and 38.8%, χ2=2.316, P=0.016). The recurrence of thymoma was a poor prognostic factor affecting the survival of patients.Meanwhile, Masaoka-Koga stage Ⅲ and Ⅳ and TNM stage Ⅲ and Ⅳ were independent risk factors for postoperative recurrence of thymoma. Conclusions:Thymectomy is safe and effective in the patients aged 65 and over, and may have a better long-term prognosis.

Objective:To proceed a comparative study of characteristics and safety of video-assisted thoracoscopic thymectomy between artificial pneumothorax combining subxiphoid-costal margin approach versus right thoracic cavity approach.Methods:From January 2018 to December 2021, 251 patients(including myasthenia gravis with thymic hyperplasia or thymoma, thymic cysts and anterior mediastinal occupying lesions)undergoing thoracoscopic extended thymectomy in our department were retrospectively studied, and their clinical data were collected.The surgical methods were divided into artificial pneumothorax combining xiphoid costal margin approach(artificial pneumothorax group, n=165)and via right thoracic approach(right thoracic group, n=86). Clinical data such as preoperative information, operative duration, blood loss, postoperative drainage, drainage duration, and surgical complication were compared between two groups.Results:There were no statistical differences in age, gender and pathology between two groups(all P>0.05). Compared with the right thoracic group, operative duration[(108.6±45.2)min vs.(127.6±42.1)min, t=-3.628, P=0.000], intraoperative blood loss[(37.9±131.7)ml vs.(107.4±284.8)ml, t=-8.215, P=0.000], postoperative drainage volume[(379.0±285.5)ml vs.(646.6±373.3 ml), t=-6.277, P=0.000]and drainage duration[(2.2±1.0)d vs.(3.1±1.0)d, t=-7.275, P=0.000]were statistically significantly decreased in the artificial pneumothorax group.No significant difference was found(all P>0.05)in phrenic nerve injury(1/165 vs.0/86, P=1.000), myasthenia crisis(3/89 vs.2/66, χ2=0.014, P=0.906), and the conversion to thoracotomy(3/165 vs.2/86, P=1.000). Conclusions:VATS thymectomy by artificial pneumothorax combining subxiphoid-costal margin approach is a safer method, having a less trauma, less bleeding and less incidence rate of complication.Especially, it is more suitable for elderly female patients who cannot be intubated in double lumen, cannot tolerate one-lung ventilation, and have pulmonary insufficiency.

Idiopathic Pulmonary fibrosis (IPF) is a chronic, progressive, fibrotic interstitial lung disease with unknown cause, which is closely related to lung cancer. A serious complication called Acute exacerbation of IPF (AE-IPF) is prone to occur after lung resection. It progresses rapidly without effective treatment and has a poor prognosis. A typical case of AE-IPF after lung cancer surgery was reported, and its clinical characteristics, imaging features, diagnosis and treatment were summarized.
