0 a device consisting of a long tube with a light inside that is used to examine the colon (= the lower part of the tube that takes solid waste out of your body)
The flexible sigmoidoscope is less expensive and safer than the colonoscope, although, given its restricted length, is likely to miss disease in the proximal colon (19;23;27).
The severity of corrective actions depended on the outcome of this assessment, with machines used to rinse bronchoscopes being considered a higher risk than those used for cystoscopes or colonoscopes.
Let us take just one example—endoscopy, which is the means of viewing and filming the inside of the stomach by gastroscope or colonoscope.
Similar instruments, the sigmoidoscope and colonoscope may be used to visualize more proximal parts of the bowels.
This can happen during colonic exploration, as a result of the electrical nature of a colonoscope.
The procedure can be carried out via enema, through the colonoscope, or through a nasogastric or nasoduodenal tube.
Physical examination may be done manually by the physician, or by using a colonoscope.
On occasion, the colonoscope can travel past the terminal ileum, but it varies from person to person.
