ERCP with Spyglass takes place at a hospital, surgery center or clinic. Beforehand, you’ll be asked to fast for about 8 hours and avoid smoking and taking certain medications. Once at the hospital, your throat will be numbed with a local anesthetic. You may also receive a sedative.
Next, your doctor puts a flexible tube (endoscope) in your mouth and passes it down your throat and esophagus to your stomach and duodenum to visualize your bile or pancreatic duct. The tube is equipped with a tiny camera fitted with the Spyglass 6,000-pixel fiber-optic probe. It transmits pictures that your doctor watches on a monitor.
Your doctor will place air/CO2 into your stomach and small intestine through the endoscope, which helps provide better pictures. A thin tube (catheter) will be placed through the endoscope to inject dye to make your ducts more visible on the X-rays. Once your doctor can see blocked areas, tools can be inserted through the endoscope to remove cells for testing, open blockages, remove or break up stones, remove tumors or insert stents.
