Summary
Adding simethicone to bowel preparation significantly improves visualization during capsule endoscopy by reducing intraluminal bubbles. This enhances the diagnostic quality of small bowel imaging.
Area of Science:
- Gastroenterology
- Medical Imaging
Background:
- Capsule endoscopy offers whole small bowel visualization.
- Standardized bowel preparation protocols are lacking.
Purpose of the Study:
- Evaluate the efficacy of simethicone in capsule endoscopy preparation.
- Assess impact on mucosal visibility and intraluminal bubbles.
Main Methods:
- 36 patients underwent capsule endoscopy after 12-hour fasting.
- 18 patients received 80 mg simethicone; 18 received none.
- Experienced endoscopists assessed mucosal visibility and bubbles in a blinded manner.
Main Results:
- Simethicone significantly improved mucosal visibility (p<0.01).
- Fewer intraluminal bubbles were observed with simethicone.
- Excellent interobserver agreement (k=0.78) and no adverse effects noted.
Conclusions:
- Simethicone enhances small bowel visualization in capsule endoscopy.
- Routine use of simethicone may improve diagnostic yield.
