Your surgeon will usually inform you of your test results on the day of the procedure unless biopsy samples were taken. These results take several days to return, and you should make arrangements with your surgeon to get the results. The effects of sedation may make you forget what you were told right after the procedure. If so, you should call your surgeon's office for the results. ERCP is generally safe when performed by surgeons who have had specific training and are experienced in this specialized endoscopic procedure.
Complications are rare, however, they can occur.
Pancreatitis due to irritation of the pancreatic duct by the X-ray contrast material or cannula is the most common complication. A reaction to the sedatives can occur. Irritation to the vein in which medications were given is uncommon, but may cause a tender lump lasting a few weeks. Warm moist towels will help relieve this discomfort. Blood transfusions are rarely required.
