Multicenter comparative trial of the V-scope system for therapeutic ERCP

Area of Science:

• Gastroenterology
• Medical Devices
• Endoscopic Procedures

Background:

• Endoscopic retrograde cholangiopancreatography (ERCP) involves complex accessory exchanges.
• Conventional duodenoscopes can present challenges in guide wire management during ERCP.

Purpose of the Study:

• To evaluate the efficiency of a new V-system duodenoscope with a modified elevator and dedicated guide wire.
• To compare the V-system's performance against conventional duodenoscopes for accessory exchange during ERCP.

Main Methods:

• A multicenter randomized trial comparing the V-system to conventional duodenoscopes.
• Patients undergoing ERCP were randomized to either the V-system or conventional group.
• Key parameters included total case time, fluoroscopy time, and accessory exchange time.

Main Results:

• The V-system demonstrated a significantly shorter median accessory exchange time (19.4 s vs. 31.7 s, P < 0.001).
• Guide wire repositioning was required less frequently with the V-system (P = 0.0005).
• The V-system achieved effective guide wire locking in 89% of exchanges.

Conclusions:

• The V-system effectively secures the guide wire during ERCP accessory exchanges.
• This system offers enhanced efficiency for ERCP procedures by reducing exchange times.
