Five convenient locations across Los Angeles, including two endoscopy centers.
Esophagogastroduodenoscopy — a visual exam of your upper digestive tract
An upper endoscopy, also called an EGD (Esophagogastroduodenoscopy), allows your gastroenterologist to directly examine the lining of your esophagus, stomach, and the first portion of your small intestine (duodenum). A thin, flexible tube with a camera is gently passed through your mouth. The procedure is quick, performed under sedation, and is one of the most common and safe procedures in gastroenterology.
Your doctor may recommend an upper endoscopy to evaluate or treat the following conditions:
The gold standard for colorectal cancer screening and lower GI evaluation
A colonoscopy is a procedure that allows your gastroenterologist to examine the entire lining of your large intestine (colon) and rectum using a long, flexible scope with a camera. It is the most effective screening tool for colorectal cancer — the third most common cancer in the United States — and can detect polyps before they become cancerous. When polyps are found, they are often removed during the same procedure.
Endoscopic Retrograde Cholangiopancreatography — diagnosis and treatment of bile duct and pancreatic conditions
ERCP (Endoscopic Retrograde Cholangiopancreatography) is an advanced, specialized procedure that combines endoscopy and X-ray imaging to diagnose and treat conditions of the bile ducts, gallbladder, and pancreas. A flexible scope is passed through the mouth and guided to the small intestine, where dye is injected and X-ray images are taken of the ducts. ERCP is both a diagnostic and therapeutic tool — meaning problems found during the procedure are often treated in the same session.
A targeted exam of the rectum and lower colon — quick, with minimal preparation
A flexible sigmoidoscopy is a procedure that allows your gastroenterologist to examine the rectum and the lower portion of your colon (the sigmoid colon) using a short, flexible tube with a camera. It is similar to a colonoscopy but examines only the last two feet of the colon. It requires much simpler preparation — typically just one or two enemas — and can often be performed without sedation, making it a convenient option for evaluating lower GI symptoms.
