Indications and findings of colonoscopy in patients presenting to the endoscopy unit at Soba University Hospital in Khartoum, Sudan

Conclusion Patients presenting with iron deficiency anaemia and a rectal mass on digital examination should have a priority over others in undergoing a colonoscopy. Despite the fact that flexible sigmoidoscopy is a useful initial investigation when a delay is anticipated in doing a colonoscopy, cases with proximal colonic polyps and cancers can be missed. Performing a full colonoscopy should be the investigation of choice in symptomatic patients.
