One hundred and sixty-three consecutive video thoracoscopic procedures: the Hong Kong experience

Video-assisted thoracoscopy (VAT) offers a new approach to the diagnosis and treatment of many thoracic conditions. From September 1992 to August 1993, a total of 163 VAT procedures were successfully performed on 108 patients (87 male, 21 female; age range from 12 to 77) which consisted of 42 bleb eliminations and 64 mechanical pleurodesis for spontaneous pneumothorax, 11 wedge resections for pulmonary nodules, three wedge biopsies for diffuse pulmonary infiltrate, four thoracic sympathectomies, resections of two mediastinal masses, three pericardial windows, 10 guided pleural biopsies for undiagnosed effusions, six guided drainage of empyema and haemothorax, 16 staging of intrathoracic tumours and two explorations for penetrating thoracic trauma. There was no procedure-related mortality. Complications included one recurrence for spontaneous pneumothorax, one re-exploration for bleeding (also by VAT approach), one wound infection, and six persistent air leaks for more than 10 days. The median duration of postoperative chest tube drainage was 2 days and the median hospital stay was 4 days. It was concluded that VAT is a safe and effective approach in thoracic surgery and with further refinement in instrumentation even more procedures will be technically feasible. The long-term results of VAT are being awaited in order to define its true merits in thoracic surgery.
