A 27 year-old male was admitted to our hospital because of having bloody stool and diarrhea. Serum hemoglobin level was 7.9 g/dl. Because of bloody stool as anemia progressed, so he underwent colonoscopy. Endoscopy showed of ulcer in the ileocecal valve, it had bleeding point. Endoscopic hemostasis was performed for the vessel using Argon Plasma Coagulation (APC). After endoscopic procedure, he had no bloody stool and anemia was improved. Hemoglobin level recovered to 10 g/dl. Campylobacter jejuni was detected by the cultivation for the stool. So we used for the patient the antibiotic to Fosfomycin Calcium Hydrate for a couple of the days. On the basis of literature, endoscopic procedure is not necessary for campylobacter colitis. However, when bloody stools continues and values of hemoglobin decrease, colonoscope may be recommended as therapeutic option for enterocolitis.
