Core Tip
Core Tip: At our tertiary care academic medical center, we have noted patients referred for endoscopic retrograde cholangiopancreatography (ERCP) who increasingly require advanced cannulation techniques. This trend is noted despite increasing endoscopist experience and ERCP volume. We therefore formally evaluated this phenomenon and underlying factors. We found that complexity of cannulation at ERCP has sharply increased over the past 5 years, with more elderly patients and those with malignancy requiring advanced cannulation techniques. These data suggest that cannulation complexity may be predicted based on patient/ampulla characteristics.
