Gastroenterology Services

Getting you well and back to your normal, everyday life is our top priority. We do this by providing expert care that’s personalized, attentive and focused on finding the best treatment for your unique situation, using today’s most advanced technology and techniques.

You’re in good hands at our Digestive Disease Center. We’re staffed by renowned, fellowship-trained gastroenterologists and specially trained nurses and techs, and we’re a major affiliate of the Yale School of Medicine.

Here is an overview of the state-of-the-art resources you’ll find here:

Upper Endoscopy: A thin scope (flexible tube) is used to examine the esophagus, stomach and upper small intestine. Inflammation, peptic ulcer and cancer can be accurately diagnosed and bleeding can be controlled with metal clips or cautery.

High-resolution esophageal manometry and pH/impedence testing are used to assess esophageal function as part of a comprehensive evaluation of swallowing disorders.

Radio-frequency ablation (heat) or liquid nitrogen cryotherapy (cold) are used to eliminate abnormal tissue found in Barrett’s esophagus, a potentially pre-cancerous abnormality involving the lower esophagus. Once diagnosed, patients with Barrett’s are monitored by periodic endoscopy exams.

Endoscopy and endoscopic ultrasound are used to diagnose and stage esophageal cancer.

Endoscopic stent placement and liquid nitrogen cryotherapy are treatment options for swallowing problems (dysphagia) due to esophageal cancer.

Endoscopic retrograde cholangiopancreatography, or ERCP, is a highly specialized technique used to diagnose and treat obstruction of the bile ducts, pancreatic duct and gallbladder.

Endoscopic ultrasound is a minimally invasive procedure to assess digestive (gastrointestinal) diseases. It uses high-frequency sound waves to produce detailed images of the lining and walls of your digestive tract and chest, organs such as the pancreas and liver, and bile ducts, esophagus and lymph nodes.

Wireless Capsule Endoscopy—in which you swallow a pill-sized video camera—allows your doctor to non-invasively look at the lining of your entire small intestine. It is used to detect sources of bleeding, ulcers, tumors and polyps.

Double balloon enteroscopy provides non-surgical access (via a long endoscope) to the entire small intestine to treat bleeding, diagnose cancer and remove polyps. Ours is the only program in the entire state to offer this procedure.

Colonoscopy involves passing a thin scope (flexible tube) through the colon to detect and painlessly remove polyps, which are potentially precancerous growths. Endoscopic mucosal resection is a special technique performed by our advanced endoscopists during colonoscopy to remove large polyps, avoiding the need for surgery.

  • Colon cancer is also diagnosed by colonoscopy, and patients are then referred to our nationally recognized Cancer Center for comprehensive staging, minimally invasive surgery, and state-of-the-art cancer care.
  • Ulcerative colitis and Crohn’s disease are chronic inflammatory conditions that are diagnosed and monitored using colonoscopy. The Digestive Disease Center at Norwalk Hospital provides comprehensive care for these chronic diseases including diet and lifestyle counseling, skilled use of biologics and immunotherapy, and surgery when required.

Minimally invasive surgery is performed by colorectal surgeons for anorectal disorders including hemorrhoids, fistulae, anal fissures and pelvic floor disorders.
