Colonoscopy
A colonoscopy is a diagnostic procedure used to examine the inner lining of the colon (large intestine) and rectum. It involves inserting a flexible tube with a camera, called a colonoscope, through the rectum to inspect the colon for abnormalities. The distal small bowel can also be examined. This procedure is commonly recommended for symptoms such as persistent abdominal pain, rectal bleeding, unexplained weight loss, and changes in bowel habits, including chronic diarrhoea or constipation.
During a colonoscopy, the doctors can identify and investigate issues like polyps, tumours, inflammation, or bleeding. The doctor can often perform biopsies or remove polyps during the same procedure if abnormalities are found. Colonoscopy is a key tool in the early detection of colorectal cancer and other gastrointestinal disorders.
Gastroscopy
Gastroscopy is a diagnostic procedure used to examine the lining of the oesophagus, stomach, and the duodenum (first part of the small intestine). It involves inserting a flexible tube with a camera, called a gastroscope, through the mouth and down the throat to view these areas.
This procedure is often recommended for symptoms such as persistent abdominal pain, nausea, vomiting, difficulty swallowing, or unexplained weight loss. It can help diagnose conditions like gastritis, ulcers, tumours, or inflammation.
During a gastroscopy, the doctor can also take biopsies or perform treatments, such as removing polyps or controlling bleeding. Patients typically need to fast before the procedure and may receive sedation to ensure comfort. Gastroscopy is a valuable tool for both diagnosing and managing gastrointestinal disorders.
