Sarge: Lung Lobe Torsion

When 3-year-old Sarge lost his appetite and started panting for two days even in an air-conditioned room, he was referred to our specialist surgeon Dr Patrick Maguire.

X-rays and CT scan revealed pleural effusion (fluid accumulation in the chest cavity) with a right lung lobe torsion (twisting). This is a life threatening condition that requires immediate stabilisation and surgical intervention.

Lung lobe torsion

When a lung lobe twists, it causes obstruction of the bronchus and vessels. The torsed lobe is identified through a lateral intercostal thoracotomy and surgically removed with a stapling device. 

Thoracotomy (open-chest surgery): performed by Dr Maguire via an incision on the side of the chest to visualise the affected lung lobe.

Lobectomy: the affected lung lobe is surgically removed and sent for histopathology and bacterial culture.

After the torsed lung lobe is surgically removed, a chest tube is placed to allow for removal and evaluation of fluid and air from the chest cavity during post-operative period.
