ObjectiveTo compare the clinical efficacy of video-assisted thoracoscopy and thoracotomy for the treatment of encapsulated tuberculous pleurisy. MethodsWe retrospectively analyzed the clinical data of 99 patients who had underwent surgery for encapsulated tuberculous pleurisy within 3 months of disease onset in our hospital from January through December 2013. Based on the surgical mode, patients were assigned to a video-assisted thoracoscopy group, including 49 patients (35 males and 14 females, a mean age of 26.78±9.36 years), to receive video-assisted thoracoscopic pleurectomy; or a thoracotomy group, including 50 patients (31 males and 19 females, a mean age of 31.84±11.08 years), to receive conventional thoracotomic pleurectomy. The first 43 patients in the video-assisted thoracoscopy group received thoracic catheter drainage, with the drainage volume of 659.08±969.29 ml; the first 48 patients in the thoracotomy group received thoracic catheter drainage, with the drainage volume of 919.03±129.97 ml. The clinical effects were compared between the two groups. ResultsAll the patients in the video-assisted thoracoscopy group completed thoracoscopy without conversion to thoracotomy. The surgery duration and postoperative intubation time were shorter in the video-assisted thoracoscopy group than those in the thoracotomy group (surgery duration:103.00±53.04 min vs. 127.06±51.60 min, P<0.01; postoperative intubation time 3.02±0.83 d vs. 3.94±1.25 d, P<0.01). At the end of 6 months of follow-up, the forced expiratory volume in one second (FEV1>) was 2.83±0.64 L in the thoracos-copy group and 2.25±0.64 L in the thoracotomy group (P<0.01); forced vital capacity (FVC) was 3.02±0.72 L in the thora-coscopy group and 2.57±0.79 L in the thoracotomy group (P<0.05); and maximal voluntary ventilation (MVV) was 93.90± 15.86 L in the thoracoscopy group and 80.34±17.06 L in the thoracotomy group (P<0.01). ConclusionThoracoscopic surgery is feasible for patients with encapsulated pleurisy within 3 months of onset. Furthermore video-assisted thoraco-scopy will be superior to thoracotomy.
