bilobectomy
Pronunciation: BY-lo-BEK-to-mee
Surgical removal of two pulmonary lobes, typically performed when tumor involvement spans multiple lobes.
Full Definition
Bilobectomy is a complex thoracic surgical procedure involving the resection of two pulmonary lobes, most commonly the right upper and middle lobes. This procedure is indicated when lung cancer extends across the fissure between lobes or when separate primary tumors exist in adjacent lobes. Bilobectomy represents a middle ground between lobectomy and pneumonectomy, preserving more lung function than pneumonectomy while achieving complete tumor resection. The procedure requires careful assessment of respiratory function and is typically performed via open thoracotomy or video-assisted thoracoscopic surgery in selected cases.
Usage
Usage note: Specify which lobes are involved, as different combinations have varying complexity and outcomes.
In Context
- "Given the tumor's extension across the minor fissure, bilobectomy of the right upper and middle lobes was performed." — Operative note
- "Pulmonary function tests demonstrated adequate reserve for bilobectomy with predicted post-operative FEV1 of 65%." — Pre-operative assessment
