Removal of a lobe of the lung is called lobocentesis. pulmonectomy. lobectomy. bronchotomy. pneumonotomy.
The correct answer and explanation is:
The correct answer is lobectomy.
A lobectomy is the surgical removal of a lobe of the lung. The lungs are divided into sections called lobes: the right lung has three lobes (upper, middle, and lower), and the left lung has two lobes (upper and lower). When disease or damage affects one lobe, such as from cancer, infection, or severe injury, removing the affected lobe can help preserve the remaining healthy lung tissue and improve overall lung function.
Here is a breakdown of the other terms and why they are incorrect for this context:
- Lobocentesis is not a standard medical term related to lung surgery. The suffix “-centesis” usually refers to a puncture to remove fluid, such as in “thoracentesis,” which involves removing fluid from the pleural space around the lungs.
- Pulmonectomy or more correctly, pneumonectomy, refers to the removal of an entire lung, not just a lobe. This is a more extensive surgery usually reserved for widespread disease affecting the entire lung.
- Bronchotomy is a surgical incision into a bronchus, the large airways within the lungs, often done to remove an obstruction or perform a biopsy. It does not involve removing lung tissue.
- Pneumonotomy is not a common or standard term in thoracic surgery. The closest related term is “pneumonectomy,” which means lung removal.
In summary, a lobectomy specifically targets one lobe of the lung for removal and is often performed to treat localized diseases while preserving as much lung function as possible. It is less extensive than a pneumonectomy and more focused than procedures involving airways alone. This makes lobectomy the correct and precise term for removal of a lung lobe.
