Which of the following describes a wedge resection of the liver?

Wedge resection of the liver refers to the surgical removal of a segment or section of liver tissue that is typically shaped like a wedge. This procedure is often performed to excise a localized tumor or lesion while preserving as much healthy liver tissue as possible. By targeting the area at the edge of the liver, the surgeon can effectively remove the affected portion while maintaining liver function.

This technique is particularly advantageous as it allows for targeted treatment of lesions while minimizing the impact on the remaining liver parenchyma. Understanding the specifics of surgical procedures such as wedge resection helps in grasping essential surgical principles and the management of liver-related conditions.
