[Endoscopic dissection of the lung. Original anatomosurgical model for practical learning]

Video-thoracoscopy (VT) and video assisted thoracic surgery (VAT) require practical skill in using specific technical infrastructure. We present an experimental model based on a polyester thoracic simulator made to a size similar to that of an adult thorax, divided into three cavities to allow placement of a fresh cardiopulmonary block from a pig weighing approximately 100 kg. Fourteen thoracostomies have been performed, 8 on the right side and 6 on the left. On the left side we have also placed a 4 x 3 cm window that simulated a minithoracotomy. This design reproduces the difficulties of maneuvering in the thoracic cage for endoscopic dissection of the lung, and offers the texture of a fresh lung specimen. The 35 endoscopic dissections of the lung performed demonstrate that this model approaches surgical reality, is inexpensive and easy to manage, and does not require keeping a stable of large animals, making it an ideal tool for learning the technique of endoscopic dissection of the lung.
