This topic is about preparing for two medical tests before reversing a temporary ileostomy. These tests are a fluoroscopy, which is like a moving X-ray, and a short internal camera exam of the lower bowel. Here’s what you can expect and how to prepare:

1. **Fasting Instructions**
- You’ll need to fast for 6 hours before the tests, meaning no food or drink. Many people find that this short fasting period doesn’t usually lead to dehydration, so try to stay calm and plan to rehydrate right after the tests.
- It’s important to follow the fasting instructions carefully. If you don’t, the radiology department might have to reschedule your tests.
- If you’re worried about dehydration, consider calling your surgeon or the radiology department ahead of time to ask if you can have an I.V. for fluids during your visit.

2. **Fluoroscopy Experience**
- During fluoroscopy, you’ll see a series of real-time X-ray images on a screen. You might need to self-administer a contrast enema before the scan and hold it while lying on the table. The scan is quick to minimize radiation exposure.
- After the scan, you’ll empty the contrast in the toilet and might need to rinse with a saline enema.
- Let the staff know you have an ostomy so they can help position you comfortably.

3. **Sedation and Discomfort**
- Most fluoroscopy procedures and barium enemas are done while you’re awake. They might be uncomfortable but are usually brief.
- If a colonoscopy-style scope is used, you might be under light or full anesthesia. Check ahead to know if you’ll be awake.
- You might feel some cramping from the contrast enema, but pain is generally minimal.

4. **Eating and Drinking with an Ileostomy**
- Some radiology staff might say it’s safe for you to eat because your stool doesn’t reach the colon, but it’s best to follow standard protocols to avoid any delays.
- Fasting might be required to get clear images of the small bowel or to keep your pouch from filling during the test.

5. **Practical Tips**
- Make sure to eat and drink well up until the 6-hour fasting cut-off.
- Bring electrolyte drinks and snacks for after the procedure to help you rehydrate and regain energy.
- When you arrive, remind the technicians about your stoma so they can adjust your position if needed.
- If you’re allowed, watch the screen during the fluoroscopy—it can be interesting and help pass the time.
