NEEDLE-KNIFE TRANSDUODENAL ACCESS OF COMMON BILE DUCT: A NOVEL TECHNIQUE

Video Transcription

Video Summary

This video transcript summarizes a novel technique for accessing the common bile duct called Needle Knife Transduodenal Access. The technique is used when cannulation through the ampulla is not possible. The video discusses two cases where experienced endoscopists were unable to cannulate the ampulla due to it being located inside a diverticulum. The technique involves locating the bile duct during endoscopy, using a needle knife to dissect the duodenal wall layers, and accessing the common bile duct. A metal stent is then placed to create a fistula. The study included three patients with obstructive jaundice and multiple stones in the bile duct. The needle-knife approach was found to be effective and safe in these patients.
