| Objective To systematically review the effect of single-port video-assisted thoracoscopic surgery(SPVATS) and traditional video-assisted thoracoscopic surgery(VATS) for spontaneous pneumothorax. Methods PubMed、EMbase、CNKI 、WanFang Data and VIP were searched for the randomized controlled trials(RCT) and the retrospective studies of single—port video-assisted thoracoscopic surgery and traditional video-assisted thoracoscopic surgery for spontaneous pneumothorax. The methodological quality of the included studies were assessed. The STATA12.0 software was used for meta-analysis.Results A total of 9 studies(1 RCT and 8 retrospective studies)involving 650 patients were included. The results of meta-analysis showed that the intraoperative blood loss in the SPVATS group was less than that in the VATS group; the postoperative chest drainage time in the SPVATS group was less than that in the VATS group; and the hospitalization time in the SPVATS group was less than that in the VATS group. But there was no significant difference in recurrence rates, the operative time and the amounts of chest tube drainage after surgery.Conclusions The limited clinical trials show there are some evidences supporting the use of single-port video-assisted thoracoscopic surgery for spontaneous pneumothorax. However, more high quality, large-scale randomized clinical trials are required for more accurate assessment. |
