Located just a 1-minute walk from Shiroishi Subway Station, Sapporo Shiroishi Internal Medicine & Gastroenterology Clinic specializes in internal medicine and gastroenterology. The clinic's most notable feature is painless endoscopic examinations performed by endoscopy specialists using sedatives. While many people associate gastroscopy and colonoscopy with discomfort, the clinic provides an examination environment that minimizes patient burden, including transnasal endoscopy for those who prefer not to have the scope inserted through the mouth. For busy patients, the clinic accepts colonoscopy for first-time visits without prior consultations, demonstrating consideration for convenience. The facility features a dedicated endoscopy floor with eight semi-private rooms for taking laxatives and six restrooms, allowing pre-examination preparation in a privacy-conscious environment. Additionally, the clinic is equipped with CT scanning equipment, which is rarely found in small clinics, enabling head, chest, and abdominal CT examinations to be completed on-site. The CT system used reduces radiation exposure by 40% compared to conventional models. All appointments require reservations. The clinic provides services in English, accepts credit cards and electronic payments, and offers affiliated parking facilities for convenient access. Barrier-free equipment is also available, creating an accessible environment for a wide range of patients.
