Clinical focus

Dr. Kaya’s area of expertise is the diagnosis and management of inflammatory bowel disease, a group of chronic conditions that includes Crohn’s disease and ulcerative colitis. These conditions can vary considerably between patients in their location, extent and course, and treatment is usually planned individually after a careful assessment of symptoms, laboratory findings and endoscopic and imaging results. For patients seeking ulcerative colitis treatment or Crohn’s disease treatment, he reviews previous therapies and discusses the options that may be appropriate at the current stage of the disease.

Endoscopy is a central part of his practice. Endoscopic examination allows direct visualization of the lining of the digestive tract and is used both to establish a diagnosis and to monitor disease activity over time. Dr. Kaya performs endoscopic evaluation as part of gastroenterology assessment and uses the findings, together with the patient’s history and test results, to guide care planning.

How Dr. Kaya works with international patients

Dr. Kaya consults in Turkish and English, and interpreters can be arranged for patients who speak other languages. Before a visit, the Acibadem international patient team coordinates the collection of prior reports and imaging, such as MRI, CT, X-ray or ultrasound reports, laboratory and pathology results, operative notes and discharge summaries, and arranges appointments and 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. Video consultation is also available for international patients who wish to discuss their situation with Dr. Kaya remotely.
