<qa>  What is a medication that can be used to disperse the air bubbles?Video capsule endoscopy VCE is a procedure where a small camera is swallowed to examine the small bowel. Although the procedure is useful for diagnosing small bowel diseases, air bubbles can obscure the recorded images. Simethicone is a medication that can be used to disperse the air bubbles. However, prior studies using this medication have shown only a modest benefit. In our study, we would like to investigate whether increasing the amount of medication will improve the recorded images further.
