Abstract
Four cases of campylobacter colitis are reported with special reference to endoscopi-cally observed lesions of the ileocecal valve. The first patient, 36-year-old male, had periumbilical and lower abdominal pain. Endoscopy done on the 12th day from the onset, revealed redness on the ileocecal valve. The second patient, 21-year-old male, had lower abdominal pain, watery diarrhea, and fever. Endoscopy done on the 11th day from the onset, revealed ulcer formation on the ileocecal valve without any changes in the terminal ileum or in the colon. The third patient, 54-year-old female, had fever, upper abdominal discomfort, and diarrhea. Endoscopy done on the 17 th day from the onset, revealed redness on the ileocecal valve. Histology of the specimens taken from ileocecal lesions of these three cases showed non-specific inflammation. Campylobacter was not cultured from the biopsy specimens taken from the ileocecal lesions of these patients as well as normal colonic mucosa. The fourth patient, 30-year-old female, had watery diarrhea mixed with blood. Endoscopy showed no abnormality of the ileocecal valve although scattered redness was found in the sigmoid.
