Klein Infiltration Pump for Irrigation During Percutaneous Biliary Endoscopy Using SpyGlass Discover Digital Catheter

Purpose: Direct visualization and management of complex biliary pathologies by percutaneous endoscopy is becoming more common in the current interventional radiology practice because of its minimally invasive nature. However, intraprocedural visualization during cholecystoscopy is critically limited in part because of the current technique of manual irrigation during endoscopy.

Materials and Methods: In this retrospective bi-institutional study (n = 36), we examined the safety, feasibility and efficacy of using an infiltration pump during percutaneous endoscopy using the SpyGlass Discover digital catheter compared with the use of manual irrigation using the LithoVue single-use digital catheter.

Results: The technical success was 100% in both groups, but the clinical success was 76.48% in the manual irrigation group compared with 100% in the pump irrigation group. The intraprocedural time and total number of procedures needed were also lower in the pump irrigation group. No minor or major complications were observed in either group.

Conclusions: The Klein high-volume infiltration pump for intermittent saline irrigation is effective, feasible and safe with our study demonstrating increased clinical success and procedural efficacy with similar safety profile compared with the manual irrigation group.
