Topic Explanation:

The forum discussion revolves around a user who is 2.5 weeks post distal loop colostomy due to Crohn's disease and poor transit time. The user is experiencing a light-purple discoloration around the stoma, which is tender but not warm or red. They have been placed on antibiotics as a precaution and are seeking advice on whether the discoloration is due to skin irritation or another issue.

Advice and Insights:

1. Check Appliance Fit:
- Ensure the hole in the baseplate is not too tight around the stoma. If it is, cut the hole slightly larger and use a sealing washer to compensate for the difference.
- Consider trying a different brand of appliance, particularly one with a flexible wafer, to reduce pressure and potential bruising.

2. Consult Healthcare Professionals:
- It is advised to see a doctor or surgeon to have the skin checked, especially if there is a concern about the stoma failing or if the discoloration worsens.
- Some users suggest consulting with an ostomy nurse, although opinions on their effectiveness vary.

3. Appliance Type Considerations:
- If using a convex wafer, be aware that it can cause bruising, especially if applied too soon after surgery when the area is still swollen.
- Some users recommend starting with a flat wafer post-surgery and switching to convex only if necessary after healing.

4. Use of Sealing Washers and Rings:
- Adding a sealing washer can be beneficial regardless of the wafer type used.
- A flexible wafer or ring can help accommodate movement and reduce pressure on the skin.

5. Sample and Experiment:
- Request samples from different companies to find the most comfortable and effective appliance.
- Users have found success with products like Hollister's soft convex bags and Coloplast's Sensura Mio for flexibility and comfort.

6. Skin Protection:
- Use a liquid skin protectant, such as 3M advanced skin protectant or Marathon, to protect the skin from irritation and ensure the appliance adheres properly.

7. Monitor and Adjust:
- Keep an eye on the discoloration and tenderness. If the condition improves with changes in the appliance or additional skin protection, continue with the successful combination.
- Regularly update healthcare providers on any changes or improvements.
