This typically is associated with anatomic issues such as a redundant sigmoid colon or a transverse colon which prevents complete advancement of the colonoscope to the cecum.
The colonoscope can be passed in this direction in order to enter the terminal ileum.
On occasion, the colonoscope can travel past the terminal ileum, but it varies from person to person.
Physical examination may be done manually by the physician, or by using a colonoscope.
The procedure can be carried out via enema, through the colonoscope, or through a nasogastric or nasoduodenal tube.

Similar instruments, the sigmoidoscope and colonoscope may be used to visualize more proximal parts of the bowels.
