Endoscopy Center

Endoscopy is an outpatient procedure that allows physicians to visually examine the esophagus, stomach and intestines using an endoscope—a long, thin tube with a camera on the tip.

Endoscopic tests give your doctor crucial information for accurate diagnosis of digestive tract disorders, such as pain in the stomach or abdomen, swallowing difficulties, vomiting, indigestion, tumors and ulcers.

After scheduling an appointment at the Endoscopy Center, you'll receive detailed instructions to get you back to your daily routine as quickly as possible.

Endoscopy procedures


A colon screening—known as colonoscopy—is the single most effective early detection system for colon cancer. During a colonoscopy, a doctor uses a flexible scope with a tiny camera inside to view the entire length of the colon and see any signs of a potential problem. If polyps are discovered, they can be removed immediately with another tiny instrument inside the scope.

Advanced technology available at Portsmouth Regional Hospital allows us to perform some colon screening procedures as virtual colonoscopies using computed tomography (CT).

Current guidelines suggest starting your colon cancer screenings at 50 years old, so talk to your doctor about when and how often you need a colonoscopy.

Endobronchial ultrasound

Endobronchial ultrasound is a tool for diagnosing lung infections, lung cancer and other diseases that enlarge the lymph nodes in the chest. Endoscopic procedures may be used to take tissue samples and remove polyps, often avoiding the need for surgery.
