When instructing a client suspected of having celiac sprue to prepare for a bowel biopsy, it is important to stress the need to:
1. Eat a high-gluten diet for two days prior to surgery. 2. Eat products containing oats rather than wheat. 3. Follow a normal diet to avoid false negative results. 4. Avoid eating foods that contain wheat flour or by products.
3
Rationale: Eating additional foods containing gluten should be avoided to prevent an exacerbation of gastrointestinal symptoms if celiac sprue if suspected. Products containing oats should be closely examined since some cross-contamination can occur during the processing of grains. Clients preparing for a bowel biopsy to establish a diagnosis of celiac sprue should be instructed to continue their normal diet to avoid false negative results that could occur if gluten is removed from their diet. Excessive intake of foods containing wheat or wheat by-products should be avoided until after biopsy results are available.
