What is the Maximum Stone Size for ERCP?

Published in Medical Procedures 1 min read

There is no definitive maximum stone size for ERCP, as it depends on various factors like:

  • Stone location: Stones in the common bile duct are generally easier to remove than those in the pancreatic duct.
  • Stone shape and consistency: Rounder, softer stones are easier to retrieve than irregular, hard stones.
  • Patient's anatomy: The size and configuration of the bile duct and pancreatic duct can influence the feasibility of ERCP.
  • Operator's experience: Skilled endoscopists can manage larger stones with greater success.

Here's a general guideline:

  • Small stones (less than 10 mm): These are usually easily removed using a basket or balloon catheter.
  • Medium stones (10-20 mm): These may require fragmentation using lithotripsy or other techniques.
  • Large stones (over 20 mm): These are more challenging and may require multiple procedures or surgical intervention.

Note: The maximum stone size for ERCP is a complex issue with no single answer. It's crucial to consult with a qualified gastroenterologist to determine the best treatment approach based on individual circumstances.
