Gastroscopy uses a flexible camera instrument to examine the oesophagus, stomach and duodenum. It is also called upper gastrointestinal endoscopy. It may help investigate persistent upper digestive symptoms or swallowing difficulty and allows tissue sampling or endoscopic treatment when needed.

Colonoscopy examines the colon and rectum using a flexible camera instrument. It can investigate bowel bleeding, changes in bowel habits, inflammatory bowel disease and polyps. It is also used for colorectal cancer screening, and suitable polyps can be removed or tissue samples taken during the examination.

ERCP combines endoscopy and X-ray imaging to access the bile and pancreatic ducts. It can treat problems such as duct stones, narrowing or blockage. When diagnosis alone is needed, alternatives such as MRCP, ultrasound or endoscopic ultrasound may be used.

Balloon dilation is an endoscopic treatment that widens a narrowed area in a controlled way. For example, it may relieve swallowing difficulty caused by certain oesophageal strictures. The approach depends on the narrowing’s cause, location and characteristics, and some patients need more than one session.

A gastric balloon temporarily occupies space in the stomach to support weight management. With an endoscopic balloon, the device is placed into the stomach using endoscopy. Assessment determines the balloon type, duration and follow-up plan; nutritional support and ongoing monitoring are part of the overall approach.

A swallowable gastric balloon reaches the stomach in capsule form; its position is checked with imaging before it is filled. An endoscopic balloon is placed using endoscopy. Devices differ in duration and removal arrangements, so selection depends on stomach health, weight-management goals and suitability assessment.

Gastroscopy preparation includes fasting, with exact eating and drinking instructions provided by the hospital team. Share your medicines, allergies and existing medical conditions beforehand. If sedation is planned, arranging someone to accompany you home is part of preparing for the procedure.

A clean colon allows the lining and polyps to be seen clearly. Preparation involves dietary adjustments and a bowel-cleansing plan. Follow the hospital’s written instructions and contact the procedure team if a problem prevents you from completing them. The plan is tailored to your health circumstances.

Sedation can continue to affect you after the examination, so arrange an escort and transport that does not require you to drive. Follow the discharge instructions about rest, eating and returning to normal activities. Discharge timing depends on the procedure and your recovery.

A biopsy is a small tissue sample examined in a laboratory. It can help assess inflammation, infection, coeliac disease or other changes; taking a biopsy does not itself mean cancer. The endoscopy findings and pathology results are considered together, and reporting time varies with the analysis needed.

Crohn’s disease is an inflammatory bowel disease causing chronic inflammation in the digestive tract. Assessment combines symptoms and medical history with blood and stool tests, endoscopy and imaging when needed. The aim is to identify the location and extent of inflammation and distinguish conditions with similar symptoms.

Ulcerative colitis is a chronic condition involving inflammation and ulcers in the colon’s inner lining. Symptoms can include diarrhoea, blood in the stool and abdominal pain. Assessment uses symptoms, blood and stool tests and endoscopy; treatment and follow-up depend on the disease’s extent and activity.

Irritable bowel syndrome (IBS) is a disorder of gut–brain interaction involving abdominal pain and altered bowel habits. Inflammatory bowel diseases (IBD), such as Crohn’s disease and ulcerative colitis, involve inflammation. Symptoms can overlap, but these are distinct conditions and require different clinical assessment.

Reflux occurs when stomach contents flow back into the oesophagus, often causing heartburn or regurgitation. Assessment begins with symptoms and medical history. Endoscopy is not required in every case; the need for it or other tests depends on the symptom pattern and response to initial management.

Fatty liver disease involves fat accumulation in the liver and may cause few or no symptoms. Evaluation considers medical history, metabolic risk factors, blood tests and imaging together. Assessing whether inflammation or liver injury accompanies the fat accumulation helps guide the follow-up plan.

Cirrhosis is advanced liver damage in which scar tissue replaces healthy tissue. Liver failure means the organ can no longer perform its functions adequately. Cirrhosis can lead to failure as it progresses. Assessment considers the underlying cause, liver function and possible complications together.

Pancreatitis is inflammation of the pancreas and can be acute or chronic. It may cause upper abdominal pain extending to the back, nausea and vomiting. Assessment uses examination, blood tests and imaging to identify the condition and causes such as gallstones. Severe or sudden pain may require urgent assessment.

A stone can remain in the gallbladder or enter a bile duct and cause blockage. Its location affects treatment: ERCP may be used for duct stones, while the gallbladder may need a different plan. Examination, blood tests and imaging help identify where the problem lies.

Screening looks for cancer or precancerous polyps even without symptoms. Timing and method depend on age and risks such as family history, previous polyps and inflammatory bowel disease. Options include colonoscopy and stool tests; a gastroenterology consultation helps establish an individual screening plan.

Helicobacter pylori infection can be checked with a urea breath test or stool testing. When endoscopy is needed, stomach tissue samples can also be assessed. Test selection, preparation and interpretation depend on symptoms and the clinical purpose of the investigation.

Yes. His scope includes liver biopsy and the diagnosis, treatment and follow-up of liver diseases. Use the appointment and contact information for Acıbadem Kayseri Hospital to arrange an assessment.
