Abstract
PURPOSE
To compare procedure and fluoroscopy time, technical and clinical success, and costs between single-use and reusable endoscopes in patients undergoing percutaneous biliary endoscopy (PBE) with lithotripsy.
MATERIAL AND METHODS
In this retrospective study, we included 34 patients (67 procedures) treated with PBE for gallstone removal from October 24, 2014, through February 12, 2020, using reusable (28 procedures) or single-use (39 procedures) endoscopes. We compared 1) procedure time, 2) fluoroscopy time, 3) technical success rate (accessing the biliary system and locating the gallstone), 4) clinical success rate (at least partial gallstone removal), 5) complication rate, and 6) cost of use. Alpha = 0.05.
RESULTS
Mean (± standard deviation) procedure time was not significantly different between single-use (136 ± 45 minutes) and reusable endoscopes (136 ± 51 minutes) (p = 0.47). Mean fluoroscopy time was significantly shorter for single-use endoscopes (11 ± 8.4 minutes) than for reusable endoscopes (18 ± 12 minutes) (p = 0.01). When comparing single-use vs. reusable endoscopes, rates were not significantly different for technical success (N=37, 95% vs. N=26, 93%) or clinical success (N=35, 90% vs. N=21, 75%) (both, p>0.05). Only 1 complication was noted in the reusable endoscope group (p=0.42). Cost per case was lower for single-use ($1500) than for reusable ($3987) endoscope procedures, primarily due to differences in capital costs and costs due to repair.
CONCLUSION
Single-use endoscopes offer the potential for less radiation exposure to the patient and lower cost per case, which may reduce financial barriers to offering PBE in interventional radiology practices. Clinical and technical success rates did not differ by endoscope type.
