Located in Hiragishi, Toyohira Ward, Sapporo City, Hokkaido, Ishi Gastroenterology and Internal Medicine Clinic is an internal medicine clinic specializing in gastrointestinal diseases. The director, who holds certifications as a specialist from both the Japanese Society of Gastroenterology and the Japan Gastroenterological Endoscopy Society, is in charge of medical care, with particular emphasis on endoscopic examinations. The clinic has introduced a high-performance endoscopy system equipped with LED light sources, which enables the detection of early lesions by enhancing the visibility of fine blood vessels and mucosal color changes. The examinations utilize transnasal endoscopy performed through the nose, which does not touch the base of the tongue, thereby minimizing the gag reflex and causing significantly less discomfort compared to conventional oral examinations. For patients with heightened anxiety, sedatives can be administered to allow examinations in a near-sleep state. Infection control measures are also prioritized, with endoscopes thoroughly cleaned with strongly alkaline electrolyzed water and disinfected with strongly acidic electrolyzed water after each examination. The clinic also supports Sapporo City's gastric cancer screening and blood-based gastric cancer risk assessment, as well as conducting COVID-19 and influenza testing. In terms of facilities, the clinic features an 18-space parking lot and barrier-free design, making it easily accessible for patients arriving by car or those with physical limitations. English-language support is also available.
