title: [A case of pseudomembranous enterocolitis which diagnosis was delayed in the outpatient clinic].
abstract: A 71-year-old male visited our hospital because of diarrhea. At first we suspected infectious colitis and levofloxacin (300 mg/day) was administered for four days. But the diarrhea continued, so performed a barium enema after about 3 weeks from onset. Round polyposis from the rectum to the sigmoid colon were found. Colonoscopy was suggested to the patient, but was rejected. However diarrhea continued and fever appeared. Ceftriaxone (1 g/day) and sparfloxacin (200 mg/day) were administered, but the symptoms increased. He was admitted about 6 weeks from onset, and the colonoscopy showed multiple round yellow-white pseudomembranes. Pseudomembranous enterocolitis diagnosed because Clostridium difficile and its toxin were positive in the feces. After oral administration of vancomycin (1.5 g/day) was started, the symptoms alleviated rapidly and disappearance of pseudomembrane was confirmed by colonoscopy.
