Background: Minimally invasive techniques are increasingly being used in pulmonary segmentectomy and combined subsegmentectomy. However, there are no reports as yet on robotic combined anatomic subsegmentectomy (CAS). In this report, we describe related clinical data and operative techniques and present our early results.
Methods: Clinical data of patients undergoing robotic CAS were retrospectively reviewed. A combined subsegmentectomy was defined as the resection of 2 or more subsegments that involved 2 or more adjacent segments. The study enrolled patients who underwent completely portal robotic CAS.
Results: Between May 2015 and January 2018, a single surgeon performed completely portal robotic CAS for 16 patients. In the CAS-treated patients, 75% of the lesions were located in the right upper lobe, and none required conversion to thoracotomy. Median operative time was 175 minutes (range, 75 to 294 minutes), and mean postoperative hospital stay was 4 days (range, 2 to 11 days). Although 1 patient experienced a prolonged air leak, the other 15 recovered uneventfully. Within a median follow-up period of 15 months, there were no deaths or tumor recurrences.
Conclusions: Completely portal robotic CAS is a safe and effective procedure in a select subset of patients, proving quite suitable for smaller (<2 cm) multisegment lung cancers, particularly lesions of the right upper lobe. A robotics approach facilitates complex and challenging CAS, the disadvantage being lengthy operative times during early acquisition of skills.
