TIPS AND TROUBLESHOOTING FOR OPERATING THE GUIDE WIRE DURING ERCP

Abstract

In recent years, ERCP has evolved into treatment as well as diagnosis, but the use of guide wires is essential for the success of the procedure. The guide wire has three functions: seeking (of the target site), leading (each device to the target site), and landmark (the pancreatic bile duct under fluoroscopy). Consequently the procedure efficiency and goal achievement rate increase, and accidents reduce. Recently, a wide variety of guide wires have been placed on the market due to the increase and complexity of treatment procedures, but the endoscopist undertakes sufficient measures and countermeasures against accidents regarding the shape of each guide wire, compatibility with the treatment tool, and operability. In this article, we will explain the basics and tips of guidewire operation in ERCP-related procedures, as well as troubleshooting, based on case presentations.
