Gastrointestinal Endoscopy

Gastrointestinal endoscopy is an important part of modern diagnosis and prevention of digestive system diseases.

During a gastroscopy, the oesophagus, stomach and duodenum are carefully examined. The procedure can help identify conditions such as inflammation, ulcers, bleeding and other abnormalities.

A colonoscopy allows examination of the large intestine and is an important tool in the diagnosis and prevention of colorectal cancer. When appropriate, polyps can be removed during the same procedure and subsequently sent for histopathological examination.

Dr Olender also performs endoscopic examinations as part of the diagnostic pathway for patients with gastrointestinal symptoms and conditions requiring further investigation.

A Patient-Centred Approach

Dr Olender places particular emphasis on patient safety, careful diagnosis and clear communication.

Before an examination, patients receive information about the procedure and preparation requirements. During the consultation, the patient's symptoms, medical history and individual risk factors are taken into consideration.

The goal is to make the diagnostic process as comfortable, safe and informative as possible while ensuring that patients understand the purpose and results of their examination.

Experience in Bariatric Care

Dr Olender is also a member of the multidisciplinary bariatric team at KCM Clinic. His work in this area includes gastrointestinal diagnostics and selected endoscopic procedures supporting the treatment of obesity, including the placement of a gastric balloon as part of an individually tailored weight-management programme.

Gastrointestinal endoscopy can play an important role in the assessment and preparation of patients undergoing bariatric treatment, helping physicians evaluate the condition of the digestive tract and identify potential medical considerations before treatment.
