Gastrointestinal & Liver Center distinguishes itself with a team of specialists and the collaboration among internal medicine physicians, pediatricians, radiologists, and surgeons with extensive clinical experience in difficult and complex gastrointestinal and liver diseases.

Led by Prof. Dr Rungsun Rerknimitr, Thailand’s leading gastrointestinal and endoscopic specialist, our Gastrointestinal & Liver Center aspire to excellence in the treatment, quality of medical specialists, health care professionals, modern medical devices and equipment, and limitless customer-based service.

The clinic management is under the concept of collaborative care. Medical specialists at MedPark work together to provide comprehensive care, starting from consultation, screening, diagnosis, treatment, prevention, and rehabilitation. Each doctor devotes his/her time to listen and answer questions from each individual patient clearly and thoroughly. The information collected from the patient will be used in precision medicine personalizing the treatment for each patient who has unique medical condition and fundamental differences.

At present, colon cancer is the third most common cancer causing death of Thai people. MedPark Hospital offers the advanced endoscopic technology and early-stage fecal screening test for hidden blood in stools for people with low risk.

Prof. Dr Rungsun and the Management of MedPark Hospital put an emphasis on ethics and standard of patient care as well as the performance of physicians. The patient care must be properly given, not too much or inadequately, to avoid unnecessary and pointless medical expenses.

Endoscopy, for example, is the advanced cancer screening technique. However, the quality of the screening result also depends on the expertise of the doctor. Therefore, MedPark Hospital has put an evaluation system in place to maintain the standard of care and endoscopic techniques. The standard-based assessment will be performed periodically as a performance indication of each doctor, leading to the most effective screening procedure.

In addition to one-stop-service medical care, MedPark Hospital aims to train health care personnel to own skills and expertise to effectively provide medical service and continuously do research and development for gastrointestinal treatment.

Colon Preparation Room

The comfort of patients is one of the key principles of MedPark Hospital. We are to provide customer-based service.
With over 20 years of gastrointestinal endoscopic experience, Prof. Dr Rungsun co-designed Gastrointestinal & Liver Center. Private restrooms are specifically arranged to provide convenience and privacy to patients as they usually spend most of their time here prior to endoscopic procedure. The private restrooms are essential to make patients feel comfortable and convenient as if they are at home. MedPark Hospital is the hospital with the greatest number of private restrooms in Thailand.
