ERCP to remove bile duct stones is an important method for the treatment of common bile duct stones, offering the clear clinical advantages of being minimally invasive and promoting quick patient recovery. During ERCP, endoscopy is utilized to confirm the location, size, and number of bile duct stones via intracholangiography, followed by targeted removal from the lower portion of the common bile duct using a specialized stone extraction basket.
The common bile duct opens into the duodenum, surrounded by the sphincter of Oddi at its lower segment. When facing larger stones, the sphincter of Oddi may need to be partially incised to expand the ductal opening, facilitating retrieval. In cases where stones are too large for direct removal, mechanical crushing (lithotripsy) is applied to break them into smaller fragments for safe extraction.
In addition to endoscopic intervention, minimally invasive choledocholithotomy can be performed via surgery. Both modalities are viable solutions for common bile duct stones; clinical selection depends on patient age, the degree of bile duct dilatation, stone size and quantity, and whether the ductal outlet is unobstructed.
