Core Tip
Core Tip: Difficult biliary cannulation remains a significant challenge during endoscopic retrograde cholangiopancreatography, even in expert hands and high-volume centers, which has been shown to directly impact technical success and patient outcomes. This comprehensive review highlights current strategies available in hand for managing such clinical scenarios when encountered, including early identification of risk factors, optimized guidewire techniques, and the judicious use of advanced approaches such as pre-cut sphincterotomy, double guidewire technique, transpancreatic septotomy and endoscopic ultrasound-guided rendezvous technique. Understanding the timing and escalation to alternative methods or referral is critical. A structured, stepwise approach by practicing endoscopists enhances technical success and reduces complications in such challenging clinical scenarios.
