A retrospective evaluation of risk factors for an inadequate surgical margin in preoperative lipiodol marking for small-sized pulmonary lesions.

ABSTRACT:

Background

Accurate localization and complete resection of pulmonary nodules are crucial in management of lung cancer. Computed tomography (CT)-guided lipiodol marking aids in preoperative localization, but factors affecting marking of surgical margins remain underexplored. This study aimed to identify risk factors for inadequate surgical margin following wedge resection after preoperative CT-guided lipiodol marking for small-sized pulmonary lesions.

Methods

A retrospective study was performed in 134 patients with 140 nodules marked with lipiodol for wedge resection. Factors including required resection depth, radiological characteristics, and tumor diameter were assessed for their impact on resection success, which was defined as a resection margin/tumor size (M/T) ratio ≥1
