Background: Several governmental efforts have been exerted toward controlling schistosomiasis during the last decades in Egypt. This work was designed to study the prevalence of colorectal schistosomiasis in patients with different gastrointestinal symptoms. Materials and Methods: Patients presented to the gastroenterology unit with different gastrointestinal symptoms were endoscopically examined, where three to six tiny biopsies were taken from those with visible, suspected schistosomal lesions for histopathological examination and two additional rectal biopsies were taken from the apparently normal colonic mucosa. Form each patient, at least three stool samples were examined by the formal-ether concentration method for schistosoma ova. Results: Colonic abnormalities were detected in 510 out of 984 patients presented with different gut symptoms. Schistosoma mansoni was detected in 205 patients (180 males, 25 females) with an age range (18-65years). Six patients only had schistosomal polyps and excised successfully by snare polypectomy. The squash technique established the diagnosis of schistosomiasis in all endoscopically normal 118 (50.75%) cases by demonstrating the schistosomiasis ova and their associated histopathological findings showed no or minimal reaction in 96 (46.82%) cases and variable degrees of submucosal granulomata in the remaining cases. Stool examination detected the schistosomiasis ova in 25 (9.83%) patients only of the biopsy-positive cases. Conclusions: Our data revealed that despite governmental efforts, the prevalence of colorectal schistosomiasis (20.83%) is significant among patients with gut symptoms. Gaps in health care services should be detected and filled appropriately.
