Topic Explanation:
The discussion revolves around understanding and measuring parastomal hernias, specifically how to determine the size and severity of such hernias. The original poster is seeking information on how others have had the size of their parastomal hernias assessed, as their own medical report did not specify the size.

Advice and Insights:
1. Hernia Size Determination Methods:
- A CT scan can reveal the presence of a parastomal hernia but might not always provide detailed information about the size. It's important to discuss the findings with a surgeon or a specialist who can interpret the results accurately.
- An MRI scan can offer more detailed information about the size, position, and behavior of a hernia compared to a CT scan. It is crucial for the clinician to specify what details to focus on during the scan to ensure comprehensive reporting.

2. Management and Observation:
- The severity of a hernia can sometimes be observed by whether it can be flattened when lying down or by using a support belt, especially during physical activities. This can be an indicator of a mild hernia.
- It's important to address hernias early to prevent complications, even if they are not currently severe. Regular monitoring and medical consultation are advised.

3. Seeking Second Opinions:
- If the initial medical response is unsatisfactory or lacks detail, do not hesitate to seek a second opinion. It's important for patients to understand their condition fully and to feel confident in the management plan proposed by their healthcare providers.

4. Communication with Healthcare Providers:
- Effective communication with healthcare providers is crucial. Patients should insist on clear explanations and should not be shy about asking questions to understand their medical condition and the implications of any findings like a hernia.

5. Navigating Medical Appointments and Opinions:
- Consider consulting a specialist, such as a hernia surgeon, especially if the initial treatment or diagnostic response is inadequate. For logistical challenges like long travel distances to see a specialist, weigh the importance of the visit against these challenges, possibly seeking local alternatives if available.

6. Utilizing Comprehensive Medical Facilities:
- Using a teaching hospital or a comprehensive medical facility where all doctors work together can streamline the process of diagnosis and treatment, as all medical records and imaging are accessible to any consulting physician within the facility. This can prevent the need for repeated scans and ensure a coordinated approach to treatment.
