ABSTRACT
The uniportal approach for major pulmonary resections began in 2010, with the first case being reported by D González-Rivas and colleagues in La Coruña, Spain. Since then, in different countries, thoracic surgeons had been performing hundreds of cases, with more advanced and complex procedures. Nowadays, there are reports of uniportal tracheal resection and reconstruction, carinal resection, bronchoplastic procedures, lobectomies with en bloc chest wall excision, and vascular reconstruction with optimal outcomes. The development of technologies and the potential benefits of a direct view, anatomic instrumentation, better cosmesis, and, potentially, less postoperative pain have led uniportal video-assisted thoracic surgery to grow exponentially worldwide.
ABSTRACT
BACKGROUND: Surgical treatment of lung cancer has evolved to a minimally invasive approach and currently is recognized as an acceptable treatment for resectable non-small cell lung cancer (NSCLC). As the volume and complexity of cases has increased technical difficulties had arisen. Hilar and sublobar lymph nodes can represent a challenge for video-assisted thoracoscopic surgery (VATS) surgeons in order to complete a safe dissection of vascular and bronchial structures without complications or conversion. It is not unusual the patients with smoking history or benign infections in the past present with enlarged calcified nodes that are fused to the hilum, fissure and specially the bronchus which can lead to an accident during the procedure if the surgeon has no experience handling this issue. As the amount of surgeons carrying out VATS lobectomies grows it is very important for them to know what to do in this specific case so the completion of the procedure can be achieved safely. METHODS: The coordination between the surgeon and the assistant is very important in order to carry out the procedure without discomfort positions and good visualization, the use of energy devices in expert hands can help considerably during the dissection of lymph nodes in the hilum and fissure reducing the bleeding, which provides a clean operative field. It is a necessary maneuver during the dissection to find the correct adventitial plane between the lymph node and the structure before passing it. RESULTS: The videos in this article show the different maneuvers a VATS surgeon can implement when facing enlarged fussed lymph nodes in the hilum, fissure or mediastinum. Improving exposure, opening the fissure, using energy and carrying out the dissection through the correct plane are keys to complete the procedure successfully. CONCLUSIONS: With growing experience in uniportal VATS and advances in surgical technology, enlarged or fussed lymph nodes are no longer a contraindication to complete a VATS lobectomy, experience VATS surgeons have a repertory of options in order to perform a safe and effective dissection.
ABSTRACT
Uniportal thoracic surgery is being continuously adopted by thoracic units around the world. Growing interest in the procedure is demonstrated by numerous workshops and training programs along every continent. The success of the technique lies in that it does not compromise oncologic principles and be carried out safely when proper training is acquired. For a surgeon to be able to perform a uniportal lobectomy successfully and safely proper steps must be ensuring. Multiple key maneuver and tricks are inherent to the uniportal approach. This article summarizes the equipment and key steps necessary to do a uniportal lobectomy.
ABSTRACT
Video-assisted thoracic surgery (VATS) has become one of the most important advances in thoracic surgery in this generation. It has evolved continuously into a less invasive approach, being uniportal VATS the last step in this evolution. Since the first uniportal VATS lobectomy was performed in La Coruña in 2010, the procedure has suffered and exponential growth that has allowed it to widespread around the world, expanding the indications from initially early stage lung cancer cases to complex advance cases nowadays. In Costa Rica, uniportal VATS started to be used for major pulmonary resection in June 2014, thanks to the tutoring from Dr. Gonzalez-Rivas. In our center, uniportal VATS is the standard approach for minimally invasive procedures, and major pulmonary resections had only been done through the single port approach. In order to evolve and progress in the experience of the procedure, and to expand the indications in which it was being performed, a "uniportal VATS master class" was held in Rafael Angel Calderón Guardia Hospital in San José, Costa Rica, from September 16 to September 18 2015. The master class was led by Dr. Diego Gonzalez-Rivas and it counted with the contribution of Dr. Li Wentao and Dr. Yang Yang, from Shanghai Pulmonary Hospital. The course attracted almost every thoracic surgeon in our country and participants also included anesthesiologists, pulmonologists, nurses and medical students. Three uniportal VATS were performed during the course, a left lower and a right upper lobectomy and a wedge resection that was the first non-intubated VATS procedure ever performed in our country.
ABSTRACT
Video-assisted thoracoscopic surgery (VATS) has experience an exponential growth in lung anatomic resections. Since its beginnings in early 90s with the conventional multiport VATS to the more recent uniportal approach, a continuous search for a less invasive procedure has fueled the development of minimally invasive thoracic surgery. In this sense, subxiphoid uniportal VATS has surge as a uniportal option that avoids damage to the intercostal nerve created in a transthoracic approach. In order for this technique to become as an acceptable choice for lung cancer, oncologic principles must be respected, including a feasible and safe mediastinal lymphadenectomy. Although technically more difficult than other VATS approaches, a complete lymphadenectomy is possible in the hands of expert VATS surgeons through a subxiphoid approach.
