EGD (Esophagogastroduodenoscopy) and CS (Colonoscopy)EGD and CSEsophagogastroduodenoscopy and Colonoscopy
EGD and CS are performed to detect the inflammation and neoplasms of the upper GI tract and the colon, respectively. We can applicate Narrow Band Imaging system (image-enhanced endoscopic system) for precise endoscopic diagnosis and confirm histological diagnosis by endoscopic biopsy. Given that you are receiving antithrombotic agents, biopsy is safely done according to guideline. We also perform EGD and CS with intravenous sedatives. Our team physicians are highly skilled in intravenous sedatives. Please asked our physicians and staffs about intravenous sedatives.

Polypectomy
Polypectomy is feasible while performing Colonoscopy. In case of a medication with antithrombotic agents, adjustment of antithrombotic agents is needed (ex, drug cessation of clopidogrel, one-day cessation of rivaroxaban, etc…). However, Polypectomy is also safely done according to the Japanese guidelines. Please asked our physicians and staffs about polypectomy with antithrombotic agents. Colonic polyp more than 2 cm can not be accepted to resect simultaneously in our clinic. If we detect colonic polyp more than 2cm, we introduce you to the cooperative hospital with accommodation facility (Digestive Endoscopy Center in Urawa Kyosai Hospital). ・Harada H, et al.
