This equipment is used to examine the oesophagus, stomach and duodenum. When a person complains of “stomach pain”, it is not easy to tell whether that indicates a simple ulcer or whether the pain is from cancer. It is equally difficult to specify the diagnosis when the patient starts passing blood in the stool or vomiting blood. This crucial equipment is used to assess the exact nature of the problem, removing mere dependence on guesswork. The equipment can also take biopsy samples to be used for detailed lab analysis by the Pathologist who could then make an accurate diagnosis of the exact problem to enable appropriate treatment. Without an accurate diagnosis, cancer can be missed, and treatment for ulcer could be futile.
