Rectal scaping as a diagnostic tool in schistosomiasis

Scraping of the rectal mucosa was found to be a valuable method in diagnosis of schistosoma infection. Statistically significant higher positive results than stool examination were detected in Schistosoma mansoni infection. Moreover, it is useful in diagnosis of Schistosoma haematobium Infection with rectal involvement and cases of mixed infection. Results of rectal scraping were also comparable to those obtained by snip biopsy from the rectum; however, the former is easier, does not interrupt the continuity of mucosa and needs no special equipments. It may be of value in field studies
