What this trial studies

This clinical trial aims to compare the efficacy of two techniques for biliary cannulation: fistulotomy and conventional guidewire cannulation. It will involve a randomized prospective design, assessing outcomes based on the experience level of the endoscopists performing the procedures. The study will focus on patients with conditions such as cholangiocarcinoma and choledocholithiasis, evaluating success rates and complications associated with each technique. The trial will take place at the gastrointestinal endoscopy department of a major hospital in Mexico City.

Who should consider this trial

Good fit: Ideal candidates include patients undergoing ERCP with suspected or confirmed biliary conditions such as choledocholithiasis or biliary stenosis.

Not a fit: Patients with previous ERCP, altered gastro-duodenal anatomy, or certain malignancies may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the success rates of biliary cannulation, leading to better treatment outcomes for patients with biliary diseases.

How similar studies have performed: Previous studies have shown that early precut techniques can improve cannulation success rates, suggesting that this approach may be effective.
