BackgroundSeveral procedures such as video-assisted thoracoscopic surgery (VATS) are used to make a definite diagnosis in recurrent pleural effusions so that appropriate treatment can be arranged. Single-incision thoracoscopic surgery (SITS) is the most appropriate procedure that can be used for this purpose. The contribution of SITS to diagnosis and treatment is evaluated in this study that we conducted using a single thoracoport in patients with pleural effusion.MethodsNineteen consecutive patients with pleural effusion that was recurrent or refractory to medical treatment were included in the study to be diagnosed and treated with SITS. Thoracentesis was performed and pleural fluid samples obtained in all patients before the procedure. Pleural effusion drainage was performed from the 11-mm single skin incision by using a 10.5-mm single thoracoport, and biopsy or talc pleurodesis was performed in the same session when needed.ResultsThe median age of the patients was 56.68 ± 3.05 years and there were 11 males and 8 females. The total amount of fluid drained by SITS was 1,436 ± 227 mL and the surgery lasted 81.05 ± 5.36 min. In addition, partial decortication and/or deloculation were performed in six patients and talc pleurodesis in nine patients. Fifteen patients were diagnosed with benign and four patients with malignant pleural effusion by thoracentesis, while nine patients were diagnosed with benign and ten patients with malignant pleural effusion by SITS. We therefore had six cases diagnosed as benign with thoracentesis who were diagnosed with malignant disease after SITS.ConclusionsSITS presents both diagnosis and treatment options together for pleural effusions. We believe SITS should be preferred to conventional three-port VATS to minimize the spread of infection and tumor cells to the chest wall in infectious and malignant diseases.
