Where and How is the procedure done?
The procedure will be performed at PMHC as on outpatient. The morning
of the procedure, go to the hospital and make sure you have someone
to drive you home. The nurse will start an IV and you will be given a
sedative. The doctor will insert a narrow flexible tube through the
rectum. The fiber optic scope illuminates the area, as it is passed
through the large intestine. Any abnormalities such as polyps,
diverticulitis, or tumors can be visualized. A small sample of tissue
can be taken for biopsy at this time, if the doctor feels it is needed.
Your blood pressure, heart rate and oxygen level will be monitored
before, during and after the procedure.
Following the procedure, the doctor will discuss the results of the
colonoscopy and any treatments needed. You will be monitored until you
are recovered from the sedation and have met all the discharge criteria.
