A properly executed colonoscopy can show irritated and swollen tissue, ulcers, and polyps inside the inner lining of your large intestine. The colonoscopy procedure uses a flexible, narrow tube with a light and camera on one end, called a colonoscope or scope, to look inside the colon and rectum.

What can it help diagnose?

• Weight Loss
• Internal Bleeding
• Abdominal Pain
• Changes in Bowel Habits
• Cancer Screening


EGD or esophagogastroduodenoscopy is a test completed to examine the lining of the esophagus, stomach and initial part of the small intestine. Using an endoscope, a small flexible camera, the doctor will be able to enter your esophagus to view your stomach, esophagus and duodenum.

What can it help diagnose?

• Heartburn
• Black or tarry stools or vomiting blood
• Bringing food back up (regurgitation)
• Low blood count

Capsule Endoscopy

The procedure is used to take images of your digestive track by swallowing a pill sized capsule. As the capsule travels through the digestive track, the camera will be able to take images of your digestive track, a location that is not easy to view with traditional endoscopy. A capsule endoscopy is used to identify diseases of the small intestine.

What can it help diagnose?

• Angiodysplasias
• Crohn's Disease
• Small intestinal tumors such as lymphoma, carcinoid tumor, and small intestinal cancer

Complications from Cirrhosis

General Hepatology

Our practice is on the cutting edge of hepatology, the study, prevention, diagnosis and management of diseases that affect the liver, gallbladder, biliary tree and pancreas.

GERD (Reflux)

Gastroesphageal reflux disease is a lower esphageal digestive disorder that effects the muscle between the stomach and esophagus. The reflux is a return of the contents of the stomach back up into the esophagus.

Inflammatory Bowel Disease

IBD primarily includes ulcerative colitis and Crohn's disease with are associated with severe diarrhea, pain, fatigue and weight loss.

Endoscopic Retrograde Cholangiopancreatography (ERCP)

The ERCP procedure is completed with an endoscope to provide a detailed view into your bile ducts. The ERCP is used to:

• Drain blockage
• Diagnose conditions including biliary cirrhosis
• Remove gallstones
• Expand narrow bile duct segments
• Open duct entryways
• Take tissue samples to diagnose possible tumors
