a proposed technique for the diagnosis of non-dysenteric amoebic colitis

parasitic colitis, especially entamoeba histolytica, is a well-known disorder in the middle east particularly in iran. the carrier state of the disease or the chronic type frequently remains undiagnosed or mistaken as irritable bowel syndrome which results in further discomfort and increases the incidence of associated complain. we devised a technique by inserting bisacodyl suppository and then examining the mucosal discharge for finding parasitic organisms. in our study over a period of two years on 1600 patients, which is presented here, 20% of patients who were positive underwent treatment. all signs and symptoms were disappeared after a course of treatment.
