Preface

The first Asian Single Port Video-Assisted Thoracic Surgery (VATS) Symposium was held in 2013 in Hong Kong (1). At that time, single port approach was recognized as a modality to perform thoracic surgery that could further minimize access trauma to patients. Since that successful symposium, single port VATS has expanded rapidly. Last year, the 3^rd Single Port VATS Symposium was again held in Hong Kong, with enormous progress, including technical expertise, skills, as well as advances in instruments and equipment to facilitate ever more complex and challenging surgery (2). Now the spectrum of single port VATS indications is almost equal to that of conventional multi-port VATS or open thoracotomy surgery. The publication of single port thoracic surgery also greatly increases recently, with more than 50 publications annually in 2014 and 2015.
