Procedure for endoscopic removal of bile duct stones using a duodenoscope

Generally, the surgical procedure is divided into the following steps: disinfection and anesthesia, insertion of a duodenoscope, cannulation of the bile duct, dilation of the bile duct opening, and removal of bile duct stones. The specific procedural steps are as follows:

1. Prior to surgery, thoroughly disinfect the abdominal area and surrounding skin, and administer intravenous combined anesthesia.

2. Insert the duodenoscope through the mouth, passing through the stomach into the duodenum.

3. Cannulate the bile duct to locate the common bile duct, inject contrast agent, and identify the exact location of the stones.

4. Use balloon dilation to enlarge the opening of the bile duct.

5. Extract the stones using a stone retrieval basket or balloon catheter. However, if the stones are large, they must first be fragmented before being removed one by one.

Note: This method for removing bile duct stones is generally suitable for smaller stones. For larger stones, prompt medical attention is recommended. It is advised to visit a正规 hospital and undergo the procedure under the guidance of a qualified physician.
