Areas of interest for the
Gastroenterology DOCTOR

The department that studies the esophagus, stomach, small and large intestines is called gastroenterology. Other organs that the gastroenterology department deals with are the liver, spleen, gallbladder and pancreas.

When diagnosing the diseases of these organs, procedures such as endoscopy, colonoscopy, ERCP and ultrasound are part of the three-year gastroenterology residency training.

The main diseases that the gastroenterology department deals with diagnosis and treatment are:

  • Reflux disease, difficulty swallowing, esophageal cancer
  • Gastritis, stomach ulcer, stomach cancer
  • Celiac disease, Crohn’s disease
  • Ulcerative colitis, colon polyps, colon cancer, diverticular disease, chronic constipation, chronic diarrhea, hemorrhoids and anal fissure
  • Hepatitis, hepatitis B, Hepatitis C, autoimmune hepatitis, Primary biliary cirrhosis, Wilson’s disease, hemochromatosis, cirrhosis, liver transplant, liver cancer
  • Gallstones, obstructive jaundice, biliary obstruction
  • Acute pancreatitis, chronic pancreatitis, Pancreatic cancer, pancreatic cysts

frequently asked Questions

In our unit, we perform the procedures under sedoanalgesia, that is, with the support of the anesthesia department, with some intravenous drugs and completely asleep.

Patients do not hear, feel, or remember anything during the procedure.

Apart from that, we use carbon dioxide gas in the processes. Since carbon dioxide gas can pass through biological membranes very easily, the gases given to the stomach or intestine during the procedure before the patient wakes up are expelled from the lungs in the waking period without causing any swelling to the patient. Therefore, there is no gas pain after any procedure.

Therefore, endoscopy and colonoscopy procedures are completely painless.

In many endoscopy units, the device inflates the normal room gas by giving it to the stomach and intestine (a necessary procedure for imaging). However, normal room gas consists of oxygen and nitrogen, and these can stay in the stomach and intestines for a while after the procedure, while patients may experience gas pains after the procedure.

On the other hand, in units that provide special devices, carbon hydroxide gas is blown to inflate the stomach and intestines. After the process is over, the remaining carbon dioxide gas passes into the blood very easily and is excreted through the lungs. When the patient wakes up, almost all of the carbon dioxide gas given will be removed from the body. In these patients, there is no gas, bloating and gas pain after the procedure.

Polyps are bumps like moles on the inner surface of the stomach and intestines. Large ones can start from 2-3 mm and go up to 30-40 millimeters.

There are different biological types of polyps, some of which tend to turn into cancer at a high rate over time.

For example, it can take 5 to 10 years for an adenomatous polyp to form from scratch and turn into cancer.

Therefore, detecting polyps before they turn into cancer and removing them from the stomach or intestines by polypectomy is a life-saving procedure, as it will destroy the cancer before it even starts.

Since the formation of polyps increases with age, the age at which polyps can be screened by colonoscopy is accepted as 50 years old.

Colon cancer is the type of cancer that causes death due to cancer, which ranks 2nd in both men and women in the world.

On the other hand, it is one of the easiest types of cancer to prevent.

Because it is known that 95% or more of colon cancers develop from polyps.

By pre-screening with colonoscopy, these lesions are caught at the polyp stage before cancer develops, and if it is removed during the procedure with polypectomy, the body is completely freed from these cancer-causing foci before the cancer develops.

Today, the World Health Organization has decided that screening with colonoscopy would be appropriate 10 years before the age of 60, when colon cancer peaks.
It is recommended that colonoscopy screening be performed every 10 years if polyps are not detected in colonoscopy screening in people without a family history of stomach or bowel cancer.

Reflux disease may cause tissue changes in the mucous membrane of the lower surface of the esophagus as a result of the stomach contents, albeit acid or alkaline, escaping into the esophagus. This tissue change, called Barrett’s esophagus, poses a long-term risk for esophageal cancer.

In addition, in reflux patients, these back-flows can cause various problems such as burning and pressure in the chest, chronic cough, bad breath, bifurcation in the voice and otitis media.

We think that the frequency of reflux disease in the population is around 20% with the most optimistic calculations.

Especially in young patients, closure of the lower end cap of the esophagus is recommended in terms of treatment, since it will be difficult in practice to comply with the recommendations called drug therapy or general lifestyle change for many years.

Gastric valve closure operations, which are classically performed with the surgical method, can now be performed with different endoscopy methods.

GERDX, TIF, ARMS, ARMA procedures are some of the reflux surgeries performed with endoscopy. Among them, ARMA is an easy and safe method that we can do in our unit.
