Immediately after an ERCP, you can expect to feel some mild discomfort and bloating, this is normal.
You may feel drowsy or nauseated for a few hours. If the ERCP was performed as an out-patient procedure, you will have to wait for an hour or two until the sedative wears off and you might need a relative or friend to accompany you home as you will not be able to drive. However, if the ERCP was performed as an in-patient procedure, you will have to stay overnight at the hospital for close monitoring.
After the test, your doctor will inform you if he/she observed any abnormalities and if samples were taken for a biopsy. If such, your biopsy results should be ready in a few weeks and your doctor will call you with the results. The next step will depend on the results of your ERCP and if applicable, your biopsy.
