유지 혈액투석 환자에서 단일풍선 소장내시경으로 치료한 소장출혈 1예

Abstract

Anemia is a common complication of hemodialysis. It reduces the quality of life and is recognized as adverse risk factor. The cause of anemia in CKD (chronic kidney disease) include lack of erythropoietin, gastrointestinal (GI) bleeding, hypothyroidism, hidden infection, and blood loss in hemodialysis. GI bleeding is not unusual complication in patient on maintenance hemodialysis, caused by uremia, medicine (NSAIDS, antiplatelet agents, anticoagulants), angiodysplasia, and ulcer. In CKD patients, GI bleeding is found in various sites over the whole bowel. Small bowel bleeding is one of the most common causes of obscure GI bleeding and constitutes 2-10% of all GI bleeding. Regarding the small bowel bleeding, diagnosis and treatment are much improved recently with the help of wireless capsule endoscopy and double or single balloon enteroscopy. We report a case of GI bleeding due to erosion of small bowel, which was diagnosed and treated with the single-balloon enteroscopy in patients on maintenance hemodialysis.
