Summary
The double-guidewire technique improves difficult biliary cannulation success rates compared to standard methods but is less effective than transpancreatic sphincterotomy. Safety outcomes were comparable across techniques.
Area of Science:
- Gastroenterology
- Endoscopic Retrograde Cholangiopancreatography (ERCP)
Background:
- Difficult biliary cannulation is a common challenge during ERCP.
- Various techniques exist to improve cannulation success, each with potential benefits and risks.
Conclusions:
- The double-guidewire technique offers an improvement over standard methods for difficult biliary cannulation.
- Transpancreatic sphincterotomy appears to be the most effective technique for achieving cannulation success.
- The double-guidewire technique demonstrates comparable safety profiles regarding pancreatitis and complications to other evaluated methods.
