You’ll change into a hospital gown, and a small cannula will be placed in your hand or arm so we can give sedatives and any other necessary medications. Because ERCP is more complex than other endoscopies, sedation helps you stay comfortable throughout.

In the procedure room, you’ll lie on your front with your face turned to the side. We may give you oxygen through soft prongs in your nose, and monitor your heart rate and oxygen levels. A throat spray and a light sedative, combined with pain relief, and a muscle relaxant can help make the procedure safe and manageable.

Your specialist will guide a thin, flexible telescope through your mouth into your oesophagus, stomach, and duodenum. Using X-ray dye for guidance, they can remove stones, widen narrowings, place stents, or take tissue samples, all in the same procedure.

You’ll need to fast for at least six hours beforehand, though clear fluids can usually be consumed up to two hours prior. Blood tests are required within a week or two before the procedure, and any blood-thinning medications may need adjusting. ERCP usually requires sedation, a cannula for medications, and monitoring of your heart rate and oxygen. Most patients stay overnight, though some can go home after around four hours. You’ll need to arrange for someone to take you home.

ERCP is generally very safe, with over 95% of patients experiencing no complications. Your heart rate and oxygen levels are closely monitored throughout, and sedation, pain relief, and muscle relaxants help ensure you stay comfortable at all times.
