Pitfall of Wide Wedge Resection: Risk of Overlooking Surgical Margin Shortage.

ABSTRACT:

Objectives

The recent increase in sublobar resections has been driven by favourable long-term outcomes and advances in stapling devices. However, maintaining an adequate resection margin remains a critical oncological requirement. This study aimed to investigate whether deep wedge resection induces subpleural alveolar injury that could lead to margin overestimation by creating undetectable internal cavities.

Methods

We retrospectively analysed 33 consecutive patients who underwent wedge resection and CT imaging of resected lung specimens between December 2018 and February 2025. CT was performed on inflated specimens to better visualize internal lung architecture. We assessed the presence of an "empty space" adjacent to the staple line and correlated it with clinical factors,
