Expert Gastroscopy in Darwin by Dr. Maran for Digestive Health
GASTROSCOPY
Gastroscopy is an examination of the upper digestive tract, the oesophagus, stomach and duodenum using an endoscope.
An endoscope is a long, thin, flexible tube that contains a camera and a light.
The endoscope allows Dr Maran to view the lining of these organs to investigate the cause of symptoms such as heartburn, abdominal pain, difficulty swallowing, vomiting or bleeding from the digestive tract. A Gastroscopy and if necessary, biopsy is very useful in helping to make or confirm a diagnosis.



Colonoscopy in Darwin by Dr. Maran for Accurate Bowel Diagnosis
COLONOSCOPY
A Colonoscopy is a procedure that allows for the examination of the large intestine (colon) and rectum to help investigate potential abnormalities within the bowel, including cancer, inflammation, bleeding, polys and adenomas.
The procedure takes its name from the colonoscope, a long thin, flexible medical device, that contains a camera with a light. The camera in the colonoscope transmits an image from inside the bowel to a computer screen to help the surgeon identify potential problems.
During the procedure, Dr Maran spends most of the time looking for changes to the bowel lining. The colonoscope allows the surgeon to sample or remove tissue for diagnosis.
Often the colonoscopy can be combined with other procedures such as haemorrhoid banding or other perianal procedures in the same setting.
