Center for Advanced Therapeutic Endoscopy

What is CATE?

The Center for Advanced Therapeutic Endoscopy (CATE) is a specialized program at Digestive Disease Associates that focuses on diagnosing and treating complex digestive conditions using advanced, minimally invasive techniques. These procedures are often used when standard endoscopy or colonoscopy is not enough.

What Makes CATE Different?

Unlike routine procedures that focus mainly on screening or diagnosis, CATE offers advanced options that can both diagnose and treat more serious conditions—all without surgery. Our endoscopists use cutting-edge technology to perform highly specialized procedures that can remove tumors, open blocked bile ducts, manage pancreatic disease, and more. This means faster recovery, fewer complications, and personalized care for patients with complex GI needs.
