The First 24 Robotic Surgeries of Hospital da Luz.

INTRODUCTION

Robotic assisted thoracic surgery (RATS) has been growing all over the world, presenting itself as an improvement over video-assisted thoracic surgery (VATS). The main advantages are the precision of the movements, as well as the three-dimensional vision with the consequent perception of the depth of the surgical field. Thus, technically more difficult procedures, such as anatomic segmentectomies and bronchoplastic resections, are facilitated. This surgical approach also improves the quality of mediastinal lymph node dissection, extremely important in lung cancer patients.

OBJECTIVE

Analysis of the first 24 robotic thoracic surgeries performed at Hospital da Luz.

METHODS

All robotic thoracic surgeries performed at Hospital da Luz from 2/6/2016 to this date were evaluated, concerning diagnosis, type of surgery, chest drainage time, hospitalization time, morbidity and mortality.

RESULTS

Twenty-four RATS were performed, with patients having a mean age of 60.5 (39-76) years, eleven of them being male. All surgeries were performed with 3 ports of 8mm and a 12mm port for the assistant. Eighteen surgeries of pulmonary resection (75%), five surgeries for mediastinal lesions (20.8%), and one for intercostal nerve harvest for reinnervation of the brachial plexus, were performed. In the pulmonary surgeries, eleven were lobectomies (61.1%), five were anatomic segmentectomies (27.8%) and two wedge resections (11.1%). Neoplastic disease was the reason for the sixteen lung anatomic resections, two for metastatic disease and fourteen for primary lung cancer. In each case, a systemic lymph node dissection was performed. All procedures were performed without intra- or postoperative complications. Mean drainage time was 3.4 days [2-6], and mean hospitalization time was 4.8 days [3-8]. There were no mortality or major morbidity. There were two patients with prolonged air-leak up to 6 days. The morbidity after discharge was 12.5%, consisting of an apical pneumothorax that resolved spontaneously, a basal pleural effusion that resolved with outpatient thoracentesis, and a respiratory infection treated with antibiotic.

CONCLUSION

The overall evaluation of this technique is still precocious, but allows to affirm that an experienced surgeon in vats surgery has a faster learning curve with this new approach. The innovation and development of new techniques in thoracic surgery are fundamental in order to allow more effective treatments, with less pain and, when possible, lung parenchyma sparing surgeries in patients with early neoplastic lung disease.
