Introduction
In general, bile duct stones are usually treated with minimally invasive surgery, including endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic common bile duct stone removal. After administration of local anesthesia, a duodenoscope is inserted through the mouth, passing sequentially through the esophagus and stomach to locate the duodenal papilla for cannulation. Once cannulation is successful, a guidewire is inserted.
In general, bile duct stones are usually treated with minimally invasive surgery, including endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic common bile duct stone removal. Taking ERCP as an example, the procedure should be performed under the guidance of a medical professional. The specific steps are as follows:
1. Administer local anesthesia; after anesthesia takes effect, insert a duodenoscope through the mouth.
2. Pass through the esophagus and stomach sequentially, locate the duodenal papilla, and perform cannulation.
3. After successful cannulation, insert a guidewire.
4. Advance a sphincterotome along the guidewire to make a small incision in the duodenal papilla, then remove the stone from the papillary region.
