Abstract: Objective  To evaluate the effectiveness of videoassisted thoracic surgery (VATS) and thoracotomy for pulmonary sequestration. Methods  We searched PubMed， EMBASE， and CNKI up to August 20， 2017 and collected clinic trials involving treatment outcomes of pulmonary sequestration using VATS compared with thoracotomy. The RevMan 5.3 software was used for metaanalysis. Results  A total of  five cohort studies involving 191 patients were included. The results of metaanalysis showed that VATS could shorten operative time and reduce volume of intraoperative blood loss   compared with thoracotomy.  However，no statistically significant difference was found in postoperative hospital stay， chest tube duration， chest drainage amount， and postoperative complications between the two groups. Conclusion  VATS could decrease operative time and blood loss.
