TWO CASES OF ENTERBIASIS GF THE LARGE INTESTINE DIAGNOSED BY CULONOSCOPY

Abstract

We experienced two cases of enterobiasis of the large intestine where Enterobiuswarms were incidentally detected at colonoscopy. base l was a 60-year-old woman whopresented with abdominal fullness. Colonoscopy revealed a white worm in the cecum. Anattempt to catch the worm with biopsy forceps failed because the worm escaped rapidly.The worm was successfully caught and removed after attenuated with working hot biopsyforceps. The Worm was identified as Enterobius vermicularis by its morphology. Case 2was a 37-year-old man, who was referred for colonoscopy because of a positive occultblood test in the mass-screening stool examination. Colonoscapy revealed a white wormin the descending colon and at the entrance of the appendix, respectively. The worms weresuccessfully removed in the same way as in Case 1. Enterobiasis causes perianal itchingat most, but its parasitic rate is still high. We reported these two cases because similarcases will be increasingly found with increasing occasions of calonoscopy. Successfulidentification will dead to the prevention and appropriate.
