“…However, a comparative cohort study showed that ssRAB and Digital Tomosynthesis-Electromagnetic Navigation Bronchoscopy (DT-ENB) had comparable diagnostic yields and safety profiles [13]. These studies show the diagnostic yield of ssRAB for peripheral pulmonary lesions ranging from 77% to 86% [6][7][8][9][10][13][14][15]. However, there is little information on diagnostic yield of ssRAB for pure GGNs or SSNs specifically.…”

Background: Ground-glass pulmonary nodules (GGNs) are most commonly sampled by percutaneous transthoracic biopsy. Diagnostic yield for ground-glass nodules using robotic-assisted bronchoscopy has been scarcely described, with a reported yield of 70.6%. Objectives: The aim of this study is to assess diagnostic yield for GGNs using shape-sensing robotic-assisted bronchoscopy (ssRAB). Method: A retrospective study of patients who underwent ssRAB for evaluation of GGNs, from September 2021 to April 2023. Primary outcome was diagnostic yield of ssRAB for GGNs, secondary outcomes were sensitivity for malignancy, and complications that required admission or intervention. Results: A total of 23 nodules were biopsied from 22 patients. Median age was 71 years (IQR 66–81), 63.6% were female, and 40.9% had a previous history of cancer. Forty-three percent of nodules were in the right upper lobes, and the median lesion size was 1.8 × 1.21. Twelve were subsolid nodules (SSNs), and 11 were pure GGNs. Overall diagnostic yield was 87%, with a sensitivity for malignancy of 88.9%. Adenocarcinoma was the most common malignancy diagnosed (70%). No procedure-related complications were reported. Conclusion: The use of ssRAB shows a high diagnostic yield for diagnosing GGN and SSN with less than 6 mm solid component with a low risk for complications.
