When to Visit Charter Endoscopy Center

Whether you are experiencing persistent or severe symptoms related to your digestive system, such as abdominal pain and difficulty swallowing, or are interested in screening and preventive care, Charter Endoscopy Center offers many advantages. With board-certified physicians, advanced technology, and a specialized outpatient setting, our team is equipped to diagnose and treat a wide range of conditions.


An endoscopy is a medical procedure that examines certain organs and interior parts of the body using a thin, flexible device called an endoscope. The endoscope transmits real-time images of the body, allowing a doctor to visualize and diagnose various conditions.


A colonoscopy is a medical procedure that examines the inside of the large intestine (colon) and rectum using a long, flexible device called a colonoscope. The colonoscope transmits real-time images of the lining of the colon for colorectal cancer screening, diagnostics, and treatment.


A sigmoidoscopy is a medical procedure that examines the lower part of the colon, including the sigmoid colon, rectum, and the descending colon using a slim, flexible tube. Similar to a colonoscopy, a sigmoidoscopy is often used for screenings, evaluations, and polyp removal.

Esophagogastroduodenoscopy (EGD)

Also known as an upper endoscopy, an EGD is a procedure that examines the upper part of the GI tract. Using a thin, flexible device, an EGD transmits real-time images of the esophagus, stomach, and the first part of the small intestine to diagnose and treat various conditions.
