| [ Summary ] |
Clinical features and endoscopic findings of three kinds of common hemorrhagic infectious enterocolitides are described. In Campylobacter enterocolitis, characteristic endoscopic findings are scattered erythemas interspersed with normal mucosa and an ulcer on the ileocecal valve. However, diffuse inflammatory changes similar to those observed in ulcerative colitis are sometimes seen. In enteropathogenic E. coli O157 infections, diffuse hemorrhagic erosions and edematous wall thickening are observed. Differential diagnoses include ischemic colitis and antibiotic induced acute hemorrhagic colitis. In typical cases of amebic colitis, verrucous erosions with hemorrhage are observed in the rectum and cecum. However, cases which are misdiagnosed as ulcerative colitis or Crohn's disease have been observed. |
