A colonoscopy is a medical procedure used to examine the inside lining of your large intestine (colon) using a long, flexible tube with a camera, called a colonoscope. It allows your doctor to check for conditions such as inflammation (colitis), Crohn’s disease, diverticulosis, polyps, or tumors.
Flexible sigmoidoscopy is a simple and less invasive procedure used to examine the lower part of the large intestine, including the rectum and sigmoid colon. It's similar to a colonoscopy, but only looks at the left side of the colon, rather than the entire bowel.
A gastroscopy (also called an upper endoscopy or panendoscopy) is a safe and commonly performed procedure used to check the inside of your oesophagus (food pipe), stomach, and the first part of your small intestine (duodenum).
Oesophageal dilatation is a medical procedure used to gently stretch a narrowed section of the oesophagus (also known as the gullet). If you’ve been having trouble swallowing, this treatment may help food and drinks pass more easily down your throat.
A polypectomy is a procedure used to remove polyps—small growths that can form on the inner lining of your digestive tract. While most commonly removed from the colon during a colonoscopy, polyps can also appear in other areas like the stomach or small bowel and may need removal from those sites as well.
