Services
Colonoscopy
Our colonoscopies use advanced imaging technology to detect and prevent colorectal cancer through comprehensive examination of the large intestine. This procedure helps identify polyps, inflammation, and other abnormalities while patients remain comfortable under sedation. Our board-certified gastroenterologists perform thousands of these life-saving screenings annually, following national guidelines for preventive care.
Endoscopic Ultrasound
Endoscopic ultrasound combines endoscopy and ultrasound imaging to evaluate digestive tract abnormalities and surrounding organs. Our specialists use this technique to diagnose pancreatic diseases, bile duct issues, and gastrointestinal cancers with exceptional precision. The minimally invasive procedure provides detailed images that guide accurate diagnosis and treatment planning for complex cases.
Fibroscan Assessment
Fibroscan offers non-invasive liver fibrosis assessment using advanced elastography technology. This quick, painless test measures liver stiffness to detect and monitor conditions like fatty liver disease and hepatitis C. Our practice provides immediate results that help determine appropriate treatment strategies without requiring traditional liver biopsies.
ERCP
Endoscopic retrograde cholangiopancreatography (ERCP) diagnoses and treats disorders of the bile ducts and pancreas. Our experts perform therapeutic interventions like stone removal and stent placement during this procedure. This specialized technique combines diagnostic imaging with immediate treatment options for patients with complex biliary system conditions.
Capsule Endoscopy
Capsule endoscopy uses a swallowable video capsule to examine the small intestine's lining. This innovative technology captures thousands of images as it passes naturally through the digestive tract. Our physicians use this method to investigate unexplained bleeding, anemia, and suspected small bowel diseases when traditional endoscopy cannot reach these areas.

I have been going to Colorado Springs Endoscopy Center for over a decade now. I just got my latest colonoscopy and it was a great experience. Dr Baker is the best doctor I've ever had. The entire practice is very professional and they know what they are doing. If you are reading reviews on this practice, it's time to stop searching-this is the place you want!
