Clinical focus

Dr. Okan’s clinical work is centered on digestive system disorders. This covers the assessment and management of symptoms and conditions arising in the digestive tract, with care planned around each patient’s history, examination findings and previous investigations. Where appropriate, the evaluation draws on existing reports and imaging so that earlier findings can be taken into account before any further tests are proposed.

His second listed area of expertise is gastrointestinal endoscopy. Endoscopic examination allows the lining of the digestive tract to be viewed directly and, when indicated, tissue samples to be taken for further analysis. Whether an endoscopic procedure is suitable, and which type, depends on the individual patient’s symptoms, medical history and prior test results, and is decided after clinical assessment. Dr. Okan discusses the purpose of any proposed procedure, what it involves and the possible alternatives with the patient beforehand.

How Dr. Okan works with international patients

Dr. Okan speaks Turkish and English, and interpreters can be arranged for patients who prefer another language. The Acibadem international patient team coordinates the collection of prior reports and imaging, arranges appointments and organizes the hospital visit. A first consultation typically covers the patient’s history and symptoms, a review of existing imaging and previous treatments, a clinical examination and a discussion of the options that may be considered. For patients abroad, a video consultation with Dr. Okan is available, which allows an initial conversation about the case and the documents that would be useful to review before any travel is planned. Any recommendations made at this stage are preliminary and depend on the findings of a subsequent in-person assessment.
