Abstract： Currently, there are two significant tendencies in the advancement and progress of video-assisted thoracoscopic surgery（VATS）, firstly, the widening surgical indications for VATS techniques, and secondly, the use of single-port VATS which is less invasive and more cosmetic. This article focuses in particular on four aspects of single-port VATS, including；（1）the individualized incision approach and its characteristics of single-port VATS；（2）single-port VATS for the treatment of pneumothorax and the development of related techniques and equipment；（3）single-port VATS for the diagnosis and treatment of thoracic diseases such as lung lobectomy；（4）the advantages and disadvantages of single-port VATS in clinical practice.
Pneumothorax and pulmonary air leakage are common emergency and complication in department of thoracic surgery. The treatment measures of air leakage include conservative observation, needle aspiration, chest tube drainage, surgical operation, and pleurodesis. In selection of treatment methods, there is no unified and feasible standard to choose a reasonable, effective and economic therapeutic regimen. Inapposite treatment will prolong hospitalization days, increase cost, even may lead to death. Therefore, sorting out and summarizing the therapies is vitally important for clinical conduction. We retrieved about 80 reports in PubMed, Sciencedirect, and CNKI while we searched "pneumothorax" or "lung air leakage" and "treatment" as key words or title in recent ten years. We review and summarize the selection and development of them.
Objective To investigate the clinical characteristics of spontaneous pneumothorax secondary to systemic lupus erythematosus (SLE). Methods A case of spontaneous pneumothorax secondary to SLE was reported and related literatures were reviewed. Results A female patient, 26 years old, complaining of repeated fever for 3 months, chest tightness and shortness of breath more than 10 days, was hospitalized in December 2016. After admission, the patient was diagnosed as acute lupus pneumonia and received glucocorticoid, cyclophosphamide and plasma exchange therapy. Sudden right chest pain happened during hospitalization. Bedside chest CT showed right pneumothorax. After closed thoracic drainage, the syndrome of the patient was improved. A total of 14 patients were reviewd but 2 patients were excluded because of incomplete data. The left patients included 9 females and 3 males. The mean age was (28.0±11.9) years. Clinical manifestations of spontaneous pneumothorax secondary to SLE were sudden chest tightness and shortness of breath accompanied by subpleural lung cavity and vesicular changes. The majority of patients could be cured with drainage. Conclusions Pneumothorax secondary to SLE is rare which is associated with the rupture of cavity and cyst in pulmonary secondary to SLE. Majority of patients with pneumothorax could be cured after closed thoracic drainage.
Objective To systematically evaluate the efficacy and safety of Single-incision thoracoscopic surgery (SITS) and two-port video-assisted thoracoscopic surgery (2P-VATS) in the treatment of spontaneous pneumothorax. Methods The databases of CNKI, PubMed, The Cochrane Libray, Web of Science, EMbase, Wanfang and Chinese Medical Association were searched by computer. Literature on SITS treatment of spontaneous pneumothorax from the establishment of the database to March 2023. The data are processed with RevMan 5.4.1. Results Finally, 107 studies were included, including 35 RCTs, 2 cohort studies, and 70 case-control studies. Meta analysis results show that compared to 2P-VATS and three port video assisted thoracoscopic surgery (3P-VATS), SITS had a shorter surgical time [SMD=–0.53, 95%CI (–0.90, –0.16), P=0.005], less intraoperative bleeding [SMD=–1.58, 95%CI (–1.93, –1.22), P<0.000 01; SMD=–1.59, 95%CI (–2.03,–1.14), P<0.000 01], shorter postoperative hospitalization time [SMD=–1.05, 95%CI (–1.29,–0.82), P<0.000 01; SMD=–1.08, 95%CI (–1.39,–0.77), P<0.000 01], and shorter postoperative drainage (catheterization) time [SMD=–0.75, 95%CI (–1.00,–0.50), P<0.000 01; SMD=–1.23, 95%CI (–1.72,–0.75), P<0.000 01], fewer postoperative complications [OR=0.34, 95%CI (0.26,0.45), P<0.000 01; OR=0.47, 95%CI (0.33,0.68), P<0.000 1], fewer postoperative recurrences [OR=0.50, 95%CI (0.33,0.75), P=0.000 8], and lighter postoperative pain [SMD=–1.71, 95%CI (–1.98,–1.45), P<0.000 01; SMD=–2.02, 95%CI (–2.46,–1.59), P<0.000 01]. Compared with 3P-VATS, 2P-VATS had less intraoperative bleeding [SMD=–1.02, 95%CI (–1.81,–0.22), P=0.01] , shorter postoperative hospitalization time [SMD=–0.59, 95%CI (–1.11,–0.06), P=0.03], shorter postoperative drainage (catheterization) time [SMD=–0.46, 95%CI (–0.85,–0.08), P=0.02], fewer postoperative complications [OR=0.36, 95%CI (0.22,0.59), P<0.000 1] , and lighter postoperative pain [SMD=–0.80, 95%CI (–1.08,–0.53), P<0.000 01]. Conclusion SITS and 2P-VATS are an effective and safe method for the treatment of spontaneous pneumothorax and worthy of further promotion and application in clinical practice. Due to limitations in the quantity and quality of included studies, the above conclusions require more large-sample, high-quality studies to be verified.
ObjectiveTo explore the safety and efficacy of the treatment of peripheral bronchopleural fistula with customized silicone plug through bronchoscope. MethodsA total of 19 patients with BPF admitted to Hunan Provincial People’s Hospital from July 2017 to May 2023 were included. Detailed medical records of the patients were collected, including etiology, fistula location, treatment methods, complications, and effective rates, to assess the safety and efficacy of customized silicone plug occlusion. ResultsThe average age of the 19 patients was 61.58 years (range from 42～84 years). The fistulas were located at the right upper lobe in 8 cases, the right middle lobe in 2 cases, the right lower lobe in 2 cases, the left upper lobe in 2 cases, and the left lower lobe in 5 cases. Causes included 9 cases after pneumonectomy, 6 cases of spontaneous pneumothorax, 1 case post Microwave Ablation Therapy for lung nodule, 1 case of advanced lung cancer under radiotherapy and chemotherapy, 1 case of candidal pneumonia, and 1 case of pulmonary tuberculosis. 15 patients were successfully occluded for the first time, 1 case failed to place the plug, and 3 cases had silicone plug dislodgement within 1 week after the procedure, with a short-term effective rate of 73.68% (14 cases). A total of 40 customized silicone plugs were placed, with an average of (2.10±0.74), and the mean diameter of the plugs used was 6.4 mm, with a range of 3 to 9 mm. Fifteen patients were recruited for long-term follow-up, with a median follow-up time of 15 months (range from 1.5 to 53 months). One patient developed a new fistula on the 45th day, who was treated with a combined small Y-type single bullet-covered stent for occlusion. One patient died of severe pneumonia 3 months postoperatively, and one died of type II respiratory failure at the 30th month, both deaths were unrelated to the interventional procedure. The long-term effective rate was 68.42% (13 cases). ConclusionPlacing customized silicone plugs through bronchoscopy can rapidly and effectively occlude peripheral BPF, with satisfactory long-term outcome.
