I'm shocked that an HMO rep. gave you these results. You certainly have the right to your results much sooner than your 6-week follow up appointment. You should have called there and told them that your lawyer told you that it would be a good idea to get know your results
The very first part of your small intestine is called your Duodenum. When there is inflammation of that tissue, it is called duodenitis. This type of inflammation can be caused by a bacterial infection, or taking arthritis medications and pain drugs such as aspirin, Advil, Motrin, Naprosyn or many others. Sometimes it's mild and other times, severe.
The stomach is J-shaped and is divided into three general areas. The upper part of the stomach near your throat is called the fundus, the middle section of the stomach is called the body, and the bottom portion of the stomach where the pyloric sphincter is located is called the Antrum. Your surgeon found a hyperplastic or (non-cancerous) polyp there.
As for the Terminal Ileum Lymphoid Hyperplasia, your lymph follicles in your intestine are enlarged and are showing protrusions of the mucosa (lining).
With these results, you don't need to make a sooner appointment but be sure to keep the one you have! Also, get a copy of your operative and pathology for your personal files!
Because a polyp was found, you should have follow up endoscopies every 2-3 years.
