RESUMEN
Objective To report the endoscopic and hispathology characteristics of the intestinal schistosomiasis, and arose enough attention to avoid missed or misdiagnosis. Methods Clinical and endoscopic and hispathology data of the intestinal schistosomiasis in 72 patients were included in this study with Olympus CF-240 colonoscopy and biopsy.Results Endoscopic appearance showed acute enteritis in 16 cases, chronic enteritis in 27 cases and a mixed type of acute and chronic enteritis in 29 cases. In acute enteritis ova were deposited intactly with lots of eosinocyte infiltration, in chronic enteritis ova were calcified and deposited with lots of lymphocytes,plasma cells infiltration and submucosal fibrosis,while in the mixed type enteritis had both acute and chronic histopathologic appearence. Five of 72 cases were found colorectal cancer simultaneously. And 14 of 72 patients had misdiagnostic history,including ulcerative colitis 7 cases, ileocecum cancer 5 cases, and colonrectal tuberculosis 2 cases.Conclusion Intestinal schistosomiasis is classified into three types of enteritis acute,chronic and the mixed type, the latter was an important and indepent type.Colonscopy findings and repeated biopsy from the suspected lesions were essential for getting correct diagnosis.
