Abstract

Background: Subxiphoid uniportal video-assisted thoracic surgery (SVATS) for major lung resections is a new approach. Clinical evidence is lacking. The aim of this article is to describe the learning curve of the 200 selected patients who underwent uniportal subxiphoid lobectomy or segmentectomy by subxiphoid midline incision, and with the lessons learned from this early experience in SVATS and from the experience with transthoracic uniportal VATS we sought to compile “tips and tricks” for managing the multiple intraoperative technical difficulties that can arise during the SVATS and help to set the recommendations for a SVATS program.
Methods: We describe the learning curve of the first 200 selected patients who underwent uniportal subxiphoid lobectomy or segmentectomy by subxiphoid midline incision From September 2014 with early-stage non-small cell lung carcinoma (NSCLC) and benign disease. We examine the rate of conversion and the operating time comparing group one (first 100 cases) with group two (subsequent 100 cases).
Results: Of the 200 consecutive selected cases (72 males, 128 females) with a mean age of 57.4±9 years, underwent either uniportal subxiphoid lobectomy or segmentectomy 136 were lobectomies and 64 were segmental resections The mean operating time was 170±45 mins; the average and after the case 86 the rate of the operating time appears to be similar. The conversion rate decrease from 13% in group one to 8% in group two.
Conclusions: There is a gradual reduction in the operating time and rate conversion with increasing experience. Lessons from our initial experience in the learning curve period in SVATS helps to create this trouble shooting guide that offers “tips and tricks” to both avoid and manage numerous intra-operative technical difficulties that commonly arise during the SVATS initial experience.
