Wire-guided biliary cannulation: a comprehensive approach to a set of techniques

Area of Science:

• Gastroenterology
• Endoscopic Procedures
• Biliary Interventions

Background:

• Biliary cannulation during ERCP is challenging, with significant failure rates.
• Wire-guided cannulation (WGC) is preferred over contrast-assisted techniques due to higher success and lower complication rates, including post-ERCP pancreatitis.
• Various WGC methods (e.g., touch, no-touch, double guidewire) and diverse accessories exist, creating a heterogeneous landscape.

Purpose of the Study:

• To review the current state of wire-guided cannulation (WGC) techniques in ERCP.
• To elucidate the advantages of WGC for biliary tree access.
• To identify areas for future research in optimizing WGC strategies.

Main Methods:

• Review of existing literature on WGC techniques for ERCP.
• Analysis of different WGC approaches and their reported outcomes.
• Synthesis of data on success rates and complication profiles.

Main Results:

• WGC is associated with improved success in cannulating the common bile duct and reduced risk of post-ERCP pancreatitis.
• The optimal WGC strategy for maximizing success and minimizing complications remains unclear.
• Operator experience significantly influences ERCP outcomes.

Conclusions:

• WGC represents a valuable advancement in ERCP for biliary access.
• Further research is needed to standardize WGC techniques and identify the most effective strategies.
• Understanding the nuances of WGC can lead to improved patient safety and procedural efficiency.
