Gastroenterology deals with diagnosis, examination and medical treatment of diseases that originate from or involve the gastrointestinal organs (mouth, esophagus, stomach, small intestine, liver, pancreas and colon). In case a cancer is suspected in these organs, biopsy procedures are mostly performed by gastroenterologists.

The Gut: Our Second Brain

It is obvious that any gastrointestinal disease may affect the whole body. To support this truth, there is a phrase that says “intestines are called the second brain”. Therefore, Gastroenterology Clinic works in cooperation with all disciplines of the medicine.

Even though Gastroenterology Clinic cooperates with Laboratory, Radiology Clinic and Pathology departments, the discovery of endoscopy is a revolutionary development in the field of Gastroenterology.   

This technology has been advanced in time and the treatment could be performed in the same session as well as diagnostic procedures.

Sensitivity and Precision: A Groundbreaking Development in Diagnosis and Treatment


What are endoscopy, esophagogastroscopy and colonoscopy?

In endoscopy, a device (endoscope) that is equipped by a light and a camera source in one end is inserted through one of the body’s natural openings and organs with lumens are examined.   

Although there are variations in names of the endoscopic procedures, the technique is identical: Esophagogastroduodenoscopy refers to endoscopic examination of the esophagus, stomach and duodenum using an endoscope. Colonoscopy refers to endoscopic examination of the colon.   

Similarly, sigmoidoscopy and rectoscopy imply endoscopic examination of the sigmoid colon-a part of the colon-and rectum, respectively.


Endoscopic retrograde cholangiopancreatography-a valuable procedure for diagnosis and treatment of hepatic, bile duct and pancreatic diseases-, is a diagnostic tool that integrates an endoscopic procedure with X-ray imaging.


An endoscope is inserted into the mouth and advanced to the esophagus, stomach and duodenum. It is investigated whether stenosis (for instance, esophagus-stomach junction), polyp (stomach and small intestine), ulcer (stomach and duodenum), cancer and other diseases exist in these organs.   

If ulcer, stenosis or polyp is identified, such conditions are treated as well in the same session. The procedure can be performed under sedation or anesthesia, when needed.



An endoscope is inserted into the anus and advanced through the entire colon. In case a polyp or ulcer is detected in the colon, such conditions can be treated at once and tumor-like formations are biopsied.   

It is a very important procedure regarding diagnosis and follow-up of colorectal cancers. The procedure can be performed under sedation or anesthesia, when needed.
