The lungs are organs of the respiratory system. Their function is to transfer oxygen into the blood and release carbon dioxide from the blood. Each lung is divided into lobes separated by fissures in the pleura. The right lung has upper, middle, and lower lobes, but the left lung has only upper and lower lobes.

X-ray of lobar pneumonia gives accurate results about the disease condition. Accordingly, the X-ray image of lobar pneumonia is a opacity that can occupy the entire lobe of the lung, usually the right lobe. However, it is necessary to distinguish lobar pneumonia from other diseases such as lobar lung tumors.

Lung cancer is one of the most common cancers in Vietnam. Lobectomy is considered a radical treatment in patients with early detection of lung cancer. In particular, laparoscopic lobectomy has many outstanding advantages compared to open surgery.
