AIM To investigate the assumption that schistosomiasis is the main cause of rectal prolapse in young Egyptian males. METHODS Twenty-one male patients between ages of 18 and 50 years with complete rectal prolapse were included in the study out of a total 29 patients with rectal prolapse admitted for surgery at Colorectal Surgery Unit, Ain Shams University hospitals between the period of January 2011 and April 2014. Patients were asked to fill out a specifically designed questionnaire about duration of the prolapse, different bowel symptoms and any past or present history of schistosomiasis. Patients also underwent flexible sigmoidoscopy and four quadrant midrectal biopsies documenting any gross or microscopic rectal pathology. Data from questionnaire and pathology results were analyzed and patients were categorized according to their socioeconomic class.RESULTS Twelve patients(57%) never contracted schistosomiasis and were never susceptible to the disease, nine patients(43%) had history of the disease but were properly treated. None of the patients had gross rectal polypsand none of the patients had active schistosomiasis on histopathological examination. Fifteen patients(71%) had early onset prolapse that started in childhood, majority before the age of 5 years. Thirteen patients(62%) were habitual strainers, and four of them(19%) had straining dating since early childhood. Four patients(19%) stated that prolapse followed a period of straining that ranged between 8 mo and 2 years. Nine patients(43%) in the present study came from the low social class, 10 patients(48%) came from the working class and 2 patients(9%) came from the low middle social class. CONCLUSION Schistosomiasis should not be considered the main cause of rectal prolapse among young Egyptian males. Childhood prolapse that continues through adult life is likely involved. Childhood prolapse probably results from malnutrition, recurrent parasitic infections and diarrhea that induce straining and prolapse, all are common in lower socioeconomic classes.
