Question:

Which one of the following choices is/are recommended in order to decrease misinterpretation when looking for leak or fistula: (Multiple choices may be correct):
1. Meticulous attention to the renal collecting system.
2. Consumption of diluted gastrografin instead of non-diluted contrast.
3. Using barium instead of Gastrografin.
4. Consumption of undiluted contrast when studying small bowel disease.
5. Hydration of the patient prior to the procedure.





Answer:

The correct answers for the question "Which one of the following choices is/are recommended in order to decrease misinterpretation when looking for leak or fistula: (Multiple choices may be correct):" are:

1. Meticulous attention to the renal collecting system.

2. Consumption of diluted gastrografin instead of non-diluted contrast.

5. Hydration of the patient prior to the procedure.



Explanation
Meticulous attention to the renal collecting system, consumption of diluted gastrografin instead of non-diluted contrast, prehydration, and performing the procedure as speedy and as prompt as possible are simple methods that can help preventing misapprehensions.

Abstract
Vicarious renal excretion of iodinated contrast introduced into the bowel is a known phenomenon that has rarely been reported. In clinical settings like Crohn`s disease in which evaluation for recto-vesical fistula is frequently requested, vicarious excretion can cause misapprehension and error in diagnosis. We present a case of Crohn`s disease in which gastrografin enema was performed to evaluate for fistula and initial interpretation was mistakenly positive, however, simple methods of elucidation were utilized to prevent error in diagnosis.
