P1.08-044 Comparison of Peri-Operative Outcomes after Robotic-Assisted Video-Thoracoscopic Lobectomies versus Segmentectomies

Abstract

Lobectomy is the standard procedure for early stage lung cancer. The role of sub-lobar resection is currently under investigation. Published comparisons between VATS, R-VATS, and open lobectomy vs. segmentectomy have been reported. The goal of our study was to compare peri-operative outcomes after R-VATS lobectomy vs segmentectomy. Comparison between these two procedures using robotic instruments has not been published. We retrospectively analyzed prospectively collected data from 253 consecutive patients who underwent lobectomy (N=208) and segmentectomy (N=45) via R-VATS performed by one surgeon. Unpaired Student’s t-test and Chi-square test were used to determine statistical significance (p≤ 0.05) of intra- and post-operative outcomes between these 2 groups.

However, the mean duration of R-VATS segmentectomy was longer than lobectomy(258min vs. 207.5min: p<0.01). Total post-operative complications didn't differ between the groups(24/43 vs. 84/208; p=0.071). Individual complications reviewed included cardiovascular, wound infections, and respiratory adverse outcomes. Only pneumothorax after chest tube removal (p=0.032) and effusion/empyema(p=0.011) requiring intervention were significant. R-VATS segmentectomy on average take longer and has more postoperative complications which can be explained by patients' underlying pulmonary disease. R-VATS segmentectomy may be considered as an alternative procedure to R-VATS lobectomy in order to conserve lung function.
