In Ege Şehir Hospital, all gastroenterology procedures for diagnosis and treatment are performed in the field of endoscopy as well as outpatient services. For diagnostic purposes, esophagogastroduodenoscopy for the upper gastrointestinal system, endoscopic retrograde cholangiopancreatography for biliary tract and pancreas examinations, colonoscopy and rectosigmoidoscopy for large intestine examination are performed. Another procedure for diagnosis is liver needle biopsy.

Gastroenterology Outpatient Service

The most commonly observed symptoms in gastroenterological diseases are prolonged constipation, prolonged diarrhea, vomiting, nausea and abdominal pain. Additionally, irritable bowel syndrome, burning sensation in the middle of chest and reflux of bitter water into the mouth (acid reflux) are some of the commonly observed symptoms. At our hospital, diagnosis and treatment of all kinds of gastroenterologic diseases are performed.

Some of the procedures performed by the department of gastroenterology for diagnosis and treatment are as follows.


Endoscopy is a procedure that is performed orally without surgery to examine the digestive system. Endoscopy is performed with the help of a flexible tube with a camera and light at its end. With the system used, the images of the digestive system can be examined on a monitor. Endoscopy can be applied for reasons such as persistent nausea and abdominal pain, sudden weight loss, ulcer, difficulty in gulping and swallowing, infections, tumors and gallstones.

Esophagogastroduodenoscopy (EGD)

Esophagogastroduodenoscopy is an endoscopic examination of stomach, the duodenum, the upper portion of the small intestine. Esophagogastroduodenoscopy can be performed to investigate diseases such as burning in the chest, nausea and vomiting, blood in mouth, poor appetite and sudden weight loss, chronic diarrhea, low blood levels and stomach ulcer.

Endoscopic Retrograde Cholangiopancreatography

Endoscopic retrograde cholangiopancreatography (ERCP) is a common endoscopic procedure in which the endoscope is advanced to further parts of small intestine and passed to the bile duct and pancreatic ducts to examine the said organs. This procedure is applied in cases of bile duct stones, jaundice without reason, and suspected disease in the biliary tract, liver, and pancreas.


Colonoscopy is an imaging method that allows the examination of the large intestine and the last part of the small intestine. Colonoscopy is performed for diagnosis and treatment of unexplained abdominal pain, sudden weight loss, prolonged diarrhea and constipation, anemia, blood in stool and intestinal polyps.


Rectosigmoidoscopy is the name given to the process of examining the last 30-40 cm part of the large intestine called the rectum and sigmoid colon. It is applied when the risk of colon cancer is detected, in case of unexplainable rectal bleeding and pain, or to diagnose prolonged diarrhea.

Liver Needle Biopsy

Liver biopsy is usually applied to determine the type of a mass detected in the liver by imaging methods such as ultrasound, tomography or MRI.
