Transthoracic thoracoscopic anatomic lobectomy with lymph node dissection is the standard surgical treatment for early stage lung cancer. However, chronic wound discomfort still remains a distinct clinical problem. This study aims to evaluate the feasibility and outcome of transumbilical anatomic lobectomy.


Under general anesthesia, a 3 cm longitudinal incision was made over the umbilicus. Under video guidance, a bronchoscope was inserted through the incision for exploration. The diaphragmatic wound was created with an electrocautery knife, and used as the entrance into the thoracic cavity. Using the transumbilical technique, anatomic lobectomy was performed with electrosurgical devices and the endoscopic vascular staplers in 15 canines.


Transumbilical endoscopic anatomic lobectomy was successfully completed hilum dissection, where one of them was sacrificed due to hemodynamic instability and the other two animals required thoracotomy to complete the operation. There were five delayed bleeding and surgical mortality caused by inadequate vessel sealing using an electrosurgical devices. Postmortem examination confirmed correct transumbilical lobectomy in the twelve animals that survived the operations.


Transumbilical anatomotic lobectomy is technically feasible in a canine model. However, the electrosurgical devices were not effective in sealing the pulmonary vessel in the current canine model.
