Located in Otsukacho, Mito City, Ibaraki Prefecture, Matsumoto Clinic offers specialized care for gastrointestinal diseases while serving as a comprehensive primary care provider. The clinic director holds multiple specialist qualifications including Gastroenterology Specialist and Instructor, Hepatology Specialist, Endoscopy Specialist and Instructor, and General Internal Medicine Specialist, covering a wide range of internal medicine from digestive diseases of the stomach, intestines, liver, gallbladder, and pancreas to management of lifestyle diseases such as diabetes, hypertension, and hyperlipidemia. The clinic places particular emphasis on high-precision endoscopic examinations. By introducing Olympus's high-definition NBI magnifying endoscopy system, combining NBI functionality that highlights vascular structures with magnifying endoscopy capable of observing lesions at approximately 100x magnification, it enables early detection of microscopic cancers that are difficult to find with conventional endoscopy. Both gastroscopy and colonoscopy are available with sedation for reduced discomfort, and procedures include colorectal polyp removal, anisakis extraction, and hemostasis for gastrointestinal bleeding. In addition to weekday consultations, the clinic operates on Saturdays with both consultations and endoscopic examinations, making it accessible for those who find it difficult to schedule time on weekdays. Services are available in English, with a location just a 2-minute walk from Otsuka Ikebata bus stop and on-site parking.
