Methods: This study is a prospective controlled trial that selected patients undergoing two-port thoracoscopic valve surgery at a certain hospital from January 2019 to December 2024. Patients were randomly assigned to the control group and the negative pressure group using a random number table method. The control group consisted of 30 patients (20 males, 10 females, mean age 42.03 ± 12.89 years), and the negative pressure group consisted of 35 patients (26 males, 9 females, mean age 41.84 ± 11.83 years). The control group received traditional chest drainage, while the negative pressure group received negative pressure chest drainage. Postoperative pain scores, hospital stay, drainage time, number of tube blockages, and incidences of pneumothorax or subcutaneous emphysema were recorded and statistically analyzed. Results: The negative pressure group had a significantly shorter postoperative drainage time compared to the control group (49.09 ± 11.99 hours vs. 79.10 ± 7.32 hours, P < 0.001). The postoperative pain score was lower in the negative pressure group (4.49 ± 1.27 vs. 7.03 ± 0.85, P < 0.001), and the hospital stay was significantly shorter (9.83 ± 1.69 days vs. 14.73 ± 2.32 days, P < 0.001). The incidence of pneumothorax or subcutaneous emphysema was significantly lower in the negative pressure group than in the control group (14.29% vs. 56.67%, P = 0.0003). Conclusion: The application of negative pressure chest drainage in patients after two-port thoracoscopic valve surgery can effectively reduce postoperative pain, shorten hospital stay, and lower the incidence of tube blockage and pneumothorax, demonstrating good clinical outcomes.展开更多

Scoliosis is one of the skeletal manifestations of TS, but most cases only require observation or conservative treatment. We experienced two adolescent TS cases in which progression of scoliosis required surgical intervention, which is very rare in TS. Case Presentation: Case 1: An 11-year-old female with TS had a single thoracic curve that rapidly progressed to a triple major curve with a 76˚ main thoracic curve at age 13.5 years. Case 2: A 14-year-old female with TS had a 59˚ single thoracic curve. In both cases, growth hormone and estrogen replacement therapy were administered preoperatively and planned postoperatively. Posterior correction and instrumented fusion using simultaneous translation on two rods technique and direct vertebral rotation with the use of multiple rod introducers were successfully performed in both cases. No crankshaft phenomenon or distal adding on were observed during those postoperative courses. Conclusions: Although curve pattern of the deformity is similar to adolescent idiopathic scoliosis (AIS), bone quality in patient with TS is lower. In the context of surgical interventions for scoliosis associated with TS, it is imperative to employ surgical techniques that take into account the suboptimal bone quality. If continuation of hormone replacement therapy is planned after corrective surgery for scoliosis in TS patients, it is essential to follow the patient closely postoperatively until bone maturation is complete.展开更多
