Abstract
Background: Low-dose computed tomography (CT) has been increasingly utilized for lung cancer screening. Localization of solitary pulmonary nodules (SPN) is crucial for resection. Two-stage localization method involves dye injection by radiologists prior to the operation. The significant interval between localization and resection is associated with a higher risk of marker failure, psychological distress and procedural complications. Single-stage localization and resection procedure under general anesthesia poses unique challenges. The aim of the study is to compare the safety, efficacy and patient satisfaction between the two methods.
Methods: This is a retrospective study comparing outcomes between two-stage and single-stage pre-operative localization of SPN. The primary study outcome was total operating time. Secondary outcomes included successful lesion localization, complication rate, 30-day readmission, mortality, patient satisfaction, and pain level.
Results: A total of 26 and 56 patients were included for the single and two-stage group respectively. Total operative time was significantly longer in the single-stage arm (mean: 188 min) than that of the two-stage arm (mean: 172 min, P<0.001) due to the additional time needed for intra-operative localization. Mean satisfaction score was significantly higher in the single-stage group than that of the two-stage group (92 vs. 52.69, P=0.004). Pain level assessed by numerical rating scales was better in the single-stage arm compared to the two-stage arm (mean: 8.8 vs. 4.85, P=0.007).
Conclusions: Single-stage localization and resection resulted in a minor increase in total operative time, higher patient satisfaction and less pain with comparable safety and efficacy to conventional two-stage approach.
