Initial results of uniportal and robot-assisted subxiphoid thymectomy.

ABSTRACT:

Background

We previously reported on subxiphoid uniportal thymectomy (SUT) and subxiphoid robotic thymectomy (SRT). This descriptive study aimed to evaluate the feasibility and safety of both SUT and SRT techniques.

Methods

Between March 2011 and December 2022, 268 patients underwent subxiphoid thymectomy. In cases demonstrating no evidence of invasion into other organs, SUT was selected due to its minimal invasiveness. In cases where the tumor was in contact with the innominate vein or those with suspected invasion into other organs, SRT with additional intercostal ports was selected due to the enhanced operability provided by the robotic system. The patients' backgrounds and the perioperative outcomes of each technique were evaluated.

Results

SUT was performed in 207 patients, while SRT was performed in 61 patients. In the SUT group, 15 patients required an additional intercostal port, and 2 patients required a median sternotomy; the SUT completion rate was 91.78%. The median operative time was 117.00 [interquartile range (IQR), 88.00-148.50] min, with a median blood loss of 5.00 (IQR, 1.00-5.00) mL. Combined resection was performed in 11 (5.31%) patients, and postoperative complications were observed in 4 patients (1.93%). None of the patients in the SRT group required median sternotomy. The median operative time was 203.00 (IQR, 158.00-278.00) min, with a median blood loss of 5.00 (IQR, 5.00-22.00) mL. Combined resection was performed in 14 patients (22.95%), and postoperative complications were observed in 5 patients (8.20%). No mortalities occurred in either group.

Conclusions

Subxiphoid thymectomy is a safe and feasible technique for both early and advanced stages of the disease requiring complex surgical procedures.
