A female Bernese Mountain Dog was diagnosed with a right middle lung lobe mass. The dog was positioned in a left lateral recumbency and one-lung ventilation was used under general anesthesia. Video-assisted thoracic surgery anatomical lobectomy was performed with 4 cm small thoracotomy and two 6-mm ports. Pulmonary vessels and bronchus were dissected and isolated individually at the hilum of the right middle lung lobe. Pulmonary vessels were ligated and were coagulated and transected using a vessel sealing device. The bronchus was ligated and transected. The mass in the right middle lung lobe was removed with a clean margin and without complications. Video-assisted thoracic surgery anatomical lobectomy was used to successfully remove a primary lung tumor in a dog.

Pulmonary artery reconstruction in lung cancer surgery is an effective surgical method to avoid pneumonectomy that leads to longer survival times with few adverse effects. The pericardium is often used for the interposition of a prosthetic conduit. A pericardial conduit can be easily and precisely constructed by surgical stapling, which facilitates pulmonary artery reconstruction. In this report, the process and pitfalls of surgical stapling are described., (Copyright © 2017 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.)

A 68-year-old female diagnosed as lung cancer with malignant effusion was treated with partial resection and intra-operative hyperthermo-chemotherapy. In such cases like carcinomatous pleuritis without disseminations, a limited operation and hyperthermo-chemotherapy with distilled water could be successful.
