ABSTRACT
BACKGROUND:
Insertion of fiducials to outline the targeted lesion allows image-guided radiotherapy, and is best achieved by endoscopic ultrasound (EUS). This study is a performance comparison of the new EUS-guided preloaded fiducial needle against Visicoil fiducials.METHODS:
Technical success, visibility score, procedural time, costs, and complications for patients who underwent EUS-guided fiducial placement in upper gastrointestinal malignancies were prospectively collected.RESULTS:
60 patients with upper gastrointestinal cancers had fiducials (14 Visicoil; 46 preloaded fiducials) inserted for image-guided radiotherapy. Technical success was 100â%, with a shorter mean (standard deviation) insertion time of 0.94 minutes (0.28 minutes) vs. 5.5 minutes (1.9 minutes; Pâ<â0.001) and higher visibility score on fluoroscopy of 2 vs. 1.18 (Pâ<â0.001) in the preloaded group. Neither group had major complications related to fiducial insertion. The cost of consumables per patient was lower in the preloaded group at US$480 (US$124) vs. US$643 (US$123; Pâ<â0.001).CONCLUSION:
Fiducial insertion for image-guided radiotherapy using the new preloaded needle is associated with 100â% technical success, shorter insertion time, and higher visibility, and is more cost-effective than the Visicoil system.
