Track 10: Capsule Endoscopy

Capsule Endoscopy

Introduction

Capsule Endoscopy is a minimally invasive diagnostic procedure that allows visualization of the gastrointestinal (GI) tract using a small, swallowable capsule equipped with a miniature camera, light source, battery, and transmitter. As the capsule travels naturally through the digestive system, it captures thousands of high-resolution images, which are transmitted to an external recording device for detailed analysis. This technology has revolutionized the evaluation of the small intestine and is increasingly used in clinical practice.

Types of Capsule Endoscopy

1. Small Bowel Capsule Endoscopy

   • Most commonly used type

   • Ideal for evaluating obscure GI bleeding, Crohn’s disease, celiac disease, and small bowel tumors

2. Colon Capsule Endoscopy

   • Designed to visualize the colon

   • Useful for colorectal cancer screening when conventional colonoscopy is incomplete or contraindicated

3. Esophageal Capsule Endoscopy

   • Focuses on rapid imaging of the esophagus

   • Used for detecting esophageal varices, Barrett’s esophagus, and reflux-related abnormalities

4. Pan-Intestinal Capsule Endoscopy

   • Enables visualization of the entire GI tract in a single procedure

   • Particularly valuable in inflammatory bowel disease (IBD) assessment and monitoring

Benefits of Capsule Endoscopy

• Non-invasive and painless procedure

• No sedation required, allowing rapid recovery

• Provides excellent visualization of hard-to-reach areas, especially the small intestine

• Improves detection of early mucosal abnormalities

• Patient-friendly and well tolerated

• Reduces the risk of complications compared to conventional endoscopy

• Useful when traditional endoscopy is incomplete or not feasible
  
  

  Conclusion

  Capsule Endoscopy is a safe, non-invasive, and patient-friendly diagnostic tool that enables detailed visualization of the gastrointestinal tract, especially the small intestine. It enhances diagnostic accuracy, improves patient comfort, and serves as an effective complement to conventional endoscopy in modern GI practice.
