Capsule Endoscopy
Nonprofits & Activism
Introduction
Capsule endoscopy is a noninvasive method used to image the small intestine, offering a unique solution for examining areas typically hard to access with conventional endoscopy. The technology utilizes a device known as a "pill camera," which resembles the size of a large vitamin pill. Inside this capsule is a miniature camera that captures images at a rate of two to three times per second.
Patients can either swallow the capsule or have it placed endoscopically, allowing the device to travel through the digestive tract while capturing detailed images of the small intestine. This innovative method enables healthcare professionals to detect potential issues in the small intestine, which standard endoscopies may miss. Regular endoscopes allow visualization only from the esophagus to the stomach and about 10 to 15 cm into the small intestine, leaving many areas unexplored.
Once swallowed, the capsule records images for approximately eight hours. The images are transmitted to a belt worn by the patient, which records the data to a device that can later be downloaded onto a computer system for further analysis. For example, in a case of gastrointestinal bleeding, images captured by the capsule can reveal multiple ulcers throughout the small intestine—damage that would otherwise go unnoticed.
Capsule endoscopy can be performed on children as small as 10 kilograms (approximately 20 pounds). For those who are unable to swallow the capsule, it can also be introduced directly into the small intestine during an upper endoscopy.
While capsule endoscopy represents a significant advancement in diagnostic technology, it is essential to note that it is not a replacement for traditional procedures like colonoscopy or upper endoscopy. Although it allows for diagnostic imaging, it does not have the capability to perform biopsies or remove polyps, as its primary function is to provide visual insight into the digestive tract.
Overall, capsule endoscopy presents a valuable option for patients of all ages, enabling healthcare providers to ensure a better standard of care while minimizing invasiveness.

FAQ
What is capsule endoscopy?
Capsule endoscopy is a noninvasive imaging technique used to visualize the small intestine using a miniature camera contained within a pill-sized capsule.
How does capsule endoscopy work?
Patients swallow the capsule or have it placed endoscopically, where it captures images of the digestive tract while traveling through the small intestine for approximately eight hours.
Who can undergo capsule endoscopy?
Capsule endoscopy can be performed on individuals of various ages, including children as small as 10 kilograms (about 20 pounds).
What are the limitations of capsule endoscopy?
While it provides valuable visual diagnoses, capsule endoscopy cannot perform biopsies or remove polyps, which necessitates follow-up procedures like colonoscopy or gastroenterology interventions for further evaluation and treatment.
What conditions can capsule endoscopy help diagnose?
Capsule endoscopy is useful for identifying issues in the small intestine, such as ulcers, bleeding, and other abnormalities that may not be visible through standard endoscopic methods.
