Abstract

Objective The aim of this study was to compare early outcome between intercostal uniportal video-assisted thoracoscopic surgery (IU-VATS) versus subxiphoid uniportal video-assisted thoracoscopic surgery (SU-VATS) in thymectomy for non-myasthenic early-stage thymoma.

Method Retrospective analysis of 76 cases completed in our hospital from May 2018 to September 2019 with subxiphoid uniportal thoracoscopic thymectomy; a single incision of ∼3 cm was made ∼1 cm under the xiphoid process. The control group included 213 patients who received intercostal uniportal thoracoscopic thymectomy from August 2015, and propensity score matching was conducted. All patients who were clinically diagnosed with thymic tumor before surgery were treated with thymectomy. Perioperative outcomes between SU-VATS (n = 76) and IU-VATS, n = 76 were compared.

Result After propensity score matching, there were no statistically significant differences between the two groups in terms of age, gender, disease stage, maximal tumor size, or other baseline demographic and clinical variables. All operation was successfully completed; there were no significant differences in the operative time (88 vs. 81 minutes, p = 0.63), intraoperative blood loss (55 vs. 46 mL, p = 0.47), postoperative drainage time (2.2 vs. 2.5 days, p = 0.72), and postoperative hospital stay (3.2 vs. 3.4 days, p = 0.78) between the two groups. The visual analog scale (VAS) on postoperative days 1, 3, 7, and 30 was less in the SU-VATS group than that in the IU-VATS group. The VAS on days 60 and 180 did not differ significantly between the two groups.

Conclusion Thymectomy using SU-VATS is a feasible procedure; it might reduce early postoperative pain and lead to faster recovery.
