Featuring: Small bowel Capsule endoscopy in our office


Capsule Endoscopy is uniquely designed to visualize the small bowel in its entirety, thus allowing for the diagnosis and observation of small bowel lesions and disease states.  

We offer two type of capsule endoscopies: Traditional Capsule Endoscopy and CapsoCam (see below)

Traditional Capsule Endoscopy

Designed to optimize your small bowel capsule endoscopy practice, the feature-rich and highly intuitive ENDOCAPSULE EC-10 System is the culmination of peerless Olympus imaging technology, continuous software innovation, thoughtful advances in procedural and practice efficiency, and a comprehensive approach to service and support. ENDOCAPSULE EC-10 sees 10% more mucosa than other capsule endoscopy platforms with a 160 degree wide-angle field of view. The 3D Track feature unique to EC-10 provides a map of the capsule’s anatomical location within the small bowel which directly correlates to clinical images, thus providing actionable information for subsequent treatment via deep enteroscopy or surgery. Olympus lens technology and sensitive high-resolution image sense technology provide incredibly clear and vivid imaging results.

CapsoCam® Plus

Award-winning technology provides comprehensive 360º imaging, eliminates need for receiver equipment during the examination. It is the only wire-free capsule endoscopy system on the market that provides a full 360° panoramic lateral image of the small bowel mucosa.

The CapsoCam Plus small bowel capsule endoscope uses four high resolution cameras placed around the circumference of the capsule to capture a full 360 degree view of the gastrointestinal tract. These cameras capture high-resolution images at a maximum frame rate of 20 frames per second (5 FPS per camera). 

CapsoCam Plus was designed to provide efficient and accurate diagnostic images and one of its most important features is its Smart Motion Sense™ technology. 

Using Smart Motion Sense Technology, CapsoCam Plus® takes pictures only when the capsule is in motion. This reduces image redundancy, which also helps to reduce physician review time.

Unprecedented Patient Comfort: No Wires, Belts or Sedation Required

Capsule endoscopy is a procedure in which you swallow a vitamin-sized capsule that takes thousands of images as it moves through your digestive system. CapsoCam Plus® is the only capsule endoscopy system that provides you total freedom and relaxation during your procedure. All of the diagnostic data is stored on-board the capsule, so the exam is performed without belts, harnesses, wires or leads. You are free to go about your normal routine during the examination.
