A hernia is normally a physical diagnosis. If there is an extensive hernia or a suspicion for a larger problem associated with the small bowel then a scan might be indicated. Most normal hernias can be diagnosed without this. Continue to follow up with your surgeon to ensure that you progress as planned. Best of luck.
Thank you for your question.It is uncommon to need any imaging studies to evaluate and treat a small umbilical hernia with a good history and physical exam. If I were worried about the size of the hernia or if there was any bowel in the hernia the study that would give the best information would be a contrasted CT scan.Best Dr. L
