    Abstract

    The feasibility of thoracoscopy for viewing the chest cavity and performing pulmonary lobectomy was assessed in 8 mongrel dogs. Previously, selective intubation had been performed in another group of dogs (n = 8) in order to monitor respiratory physiology and assess its safety. Each hemithorax was intubated using a double-barrelled endotracheal tube with one barrel placed in the left main bronchus and the other in the bifurcation of the trachea. The thoracoscope was introduced through a cannula inserted through a 2-cm incision at the ventral third of the left 5th intercostal space. The cranial, dorsal, and caudal surfaces of the pleura, lobes of the left lung, and the mediastinum were examined. A 2nd cannula was located in the dorsal 3rd of the 5th intercostal space with a prior incision and used for the introduction of forceps to separate the viscera. To biopsy, a 3rd cannula was inserted at the dorsal third of the 8th intercostal space with a prior incision, through which a 12-mm diameter stapler was introduced. Should a lobectomy be necessary, a 4th cannula is located in the middle third of the 4th intercostal space. Excision of the left caudal pulmonary lobe was performed through the incision made for the 12-mm diameter cannula (8th intercostal space); a twisting movement facilitated removal. Thoracoscopy is a procedure that can be used in dogs and is particularly suitable for examination, collection of biopsy specimens, and even lung lobectomies.
