BACKGROUND: The comparison of patients undergoing resection for mediastinal tumors in videothoracoscopic surgery (VTS) versus open surgery is still deficient. This study aimed to compare outcomes of these procedures in patients with mediastinal tumor.
METHODS: A single-center, prospective study ran from 2010 to 2013. Patients with mediastinal tumor were divided into two groups based on operative technique (VTS vs. open surgery). Outcomes were operative duration, intraoperative blood loss, chest drainage duration, postoperative hospitalization duration, pain score and complications.
RESULTS: There were 113 patients in the VTS group and 96 patients in the open group. Malignancy accounted for 31.9% and 51% of cases in the VTS and open groups, respectively. Compared to open group, VTS group had significantly shorter duration of operation (75.9±36.5 vs. 129.0±54.7 minutes), chest drainage (2.1±0.3 vs. 3.1±0.9 days), hospitalization (5.4±1.4 vs. 7.8±2.6 days), less amount of intraoperative blood loss (65.7±109.4 vs. 253.5±467.4 mL), lower postoperative pain scores (4.6±1.3 vs. 6.6±1.5), and lower complication rate (0.9% vs. 13.5%). Multivariable regression analyses confirmed the superior of VTS after adjusting for clinically relevant confounders.
CONCLUSIONS: Compared to open surgery, VTS is less traumatic and faster recovered. We advocate the VTS approach as a favored option for resection of mediastinal tumors.
