New 'Smart' cut during ERCP aims to slash complication rates
NCT ID NCT04406961
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a new way to open the bile duct during an ERCP procedure. Instead of the standard pull-type cut, doctors used a special hooked knife (ASD) designed to cut only the circular muscle layer, potentially causing less damage. Over 1,500 patients were randomly assigned to get either the new or standard technique. The main goal was to see if the new method led to fewer serious problems like bleeding, pancreatitis, or a hole in the bowel.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Antegrade Sphincterotomy Dovbenko (ASD) procedure using a special sphincterotome
What this could lead to
If successful, ASD could become a safer standard technique for opening the bile duct during ERCP, reducing the risk of serious complications like bleeding and pancreatitis.
What could go wrong
This is a completed trial, but the technique is patented and not widely adopted. Results may not apply to all patients or settings, and the procedure requires specialized training and equipment.
