Tom Savides, MD, talks with David Granet, MD, on UCSD-TV about screening for colorectal cancer, when to start screening, the various tests available and what to expect.
Endoscopy is a procedure that enables physicians to diagnose conditions inside body. The procedure uses an endoscope, which is a thin tube with a small camera and light attached. As the doctor, or endoscopist, moves the endoscope through a body passageway (such as the gastrointestinal tract or respiratory tract) or opening (such as a surgical opening), he or she can see inside the organ. Endoscopes are used for diagnosing conditions throughout the body.
Advances in endoscopic medicine have lead to the development of new endoscopic tools that enable physicians to see, diagnose and treat numerous conditions. The treatment of conditions with endoscopic tools is called therapeutic endoscopy.

A colonoscopy is an endoscopic procedure using a colonoscope to examine the colon for polyps and other abnormalities. After the patient is prepped and sedated, a thin flexible instrument with a camera attached to it is inserted through the anus and passed through the length of the large intestine to where it joins the small intestine. During the procedure, the doctor can remove polyps and take any necessary tissue samples. Read a hypothetical consultation betwen a doctor and patient about colonoscopy.
EGD is an endoscopic procedure for examining the lining of the esophagus, stomach and the first section of the small intestine – the duodenum. After the patient is prepped and sedated, a thin flexible instrument with a camera is inserted down the throat, through the esophagus and into the stomach and duodenum. Biopsies (tissue samples) can also be taken through the endoscope in this procedure.
Sigmoidoscopy is an endoscopic procedure for examining the sigmoid colon which is the part of the colon closest to the rectum and anus. The patient is prepped and a digital rectal exam is performed. Then the doctor inserts a sigmoidoscope through the anus to examine, take photographs or tissue samples as necessary, and diagnose and treat any conditions of the rectum or colon.
Endoscopic Ultrasound, or EUS, combines endoscopy and ultrasound in order to obtain images and information about the digestive tract and the surrounding tissues and organs. In EUS, an ultrasound transducer is placed on the tip of an endoscope. The endoscope is moved through a body passageway, such as the intestine. The images obtained typically have greater detail than by traditional ultrasound. The EUS Program at UC San Diego Health System, directed by Thomas Savides, MD, regularly utilizes this technique to stage cancers – meaning, to determine the level of penetration of cancer in a particular organ or organs.
Barrett’s Esophagus Treatment
We are leaders in the field of endoscopic treatment of Barrett’s esophagus - a condition that can lead to esophageal cancer. Barrett’s mucosa can be eradicated with a number of techniques including endoscopic mucosal resection (EMR), radiofrequency ablation (BARRX), cryotherapy (Polar Wand), and argon plasma coagulation. UC San Diego Health System is the first in San Diego to offer these advanced treatment options for Barrett’s esophagus and early esophageal cancer.
Endoscopic Retrograde Cholangiopancreatoscopy (ERCP)
Endoscopic retrograde cholangiopancreatography is a minimally invasive procedure that combines X-ray and video endoscope technologies to diagnose and treat conditions of the bile ducts.
Capsule endoscopy involves swallowing a capsule that contains a video camera and light. The capsule captures images as it travels through the gastrointestinal tract and transmits them to a receiver worn outside the body. At the end of the procedure, the physician downloads the data and images that were transmitted to the receiver for evaluation. This procedure allows physicians to see the small intestine, a difficult area of the body to see clearly for diagnosis without performing surgery.
Double Balloon Enteroscopy
UC San Diego Health System is the only place in San Diego to offer the double balloon enteroscopy procedure. Double balloon enteroscopy allows an endoscope to be passed through the mouth through nearly the entire small intestine to look for sources of bleeding or tumors.
UC San Diego Health System Expertise
UC San Diego Health System is at the forefront of endoscopic technology. Our physicians utilize endoscopy in combination with other diagnostic and surgical techniques to effectively address numerous conditions through the least invasive approaches possible. Our Endoscopic Ultrasound (EUS) and Interventional GI Endoscopy Program is recognized by the American Society for Gastrointestinal Endoscopy as a premier program in the United States. Program Director Thomas Savides, MD, is a past councillor for the American Society for Gastrointestinal Endoscopy.
