What is meant by segmental resection?

Segmental resection specifically refers to the surgical procedure that involves the removal of a portion of lung tissue, typically a smaller, discrete section of the lung, while preserving as much healthy lung as possible. This technique is often performed to excise localized lesions, such as tumors or infected areas, thereby ensuring that surrounding healthy tissue remains intact.

By removing only a segment rather than the entire lung, this approach aims to maintain pulmonary function and reduce recovery time compared to more extensive procedures. Understanding segmental resection is essential for surgical assistants, as it highlights the importance of targeted interventions that balance the need for therapeutic intervention with the preservation of normal anatomy and function.
