ABSTRACT
The clinical manifestation,endoscopic findings and histopathological characteristics of 162 patients with gastrointestinal schistosomiasis were retrospectively analyzed.Among 162 patients,there were 29 cases of gastric schistosomiasis and 133 cases of intestinal schistosomiasis.The main clinical manifestations included stomachache,diarrhea and mucous bloody stool.Endoscopic findings:in 29 cases of gastric schistosoniasis,18 were ulcerative type,5 inflammatory type,6 proliferative type and 7 cases combined with gastric cancer.In 133 cases of intestinal schistosomiasis,17 were acute inflammatory type,81 chronic inflammatory type,33 mixture inflammatory type and 32 combined with colorectal cancer.Forty nine cases (30.25％) were misdiagnosed for various reasons; commonly misdiagnosed as ulcerative colitis,intestinal tuberculosis,chronic gastritis,and gastrointestinal tumors.There are no specific clinical manifestations or endoscopic findings of gastrointestinal schistosomiasis; epidemiological data,endoscopy combined with multi-site multi-block biopsy may improve the diagnosis.
