Endoscopy Williamstown
Comprehensive gastrointestinal endoscopy care available throughout Williamstown.
Understanding Endoscopy
Digestive issues can be uncomfortable, painful, and even affect your daily routines and your peace of mind. Whether it’s ongoing stomach pain, unexplained changes in bowel habits, or even symptoms like bleeding, it’s natural to want clear answers as soon as possible.
Because your digestive system is vital to how your body functions, symptoms like abdominal pain, bleeding, or bowel changes should never be ignored. An endoscopy with Dr Roshan Ariyaratnam aims to offer valuable insight into what’s happening internally.
What is an Endoscopy Procedure?
Through a small, flexible camera, an endoscopy enables close examination of areas such as the oesophagus, stomach, small bowel, and colon. It’s an important tool for detecting conditions including ulcers, inflammatory bowel disease, colorectal cancer, and liver disorders.
Both colonoscopies and gastroscopies are forms of endoscopy. A gastroscopy looks at the upper part of the digestive system, while a colonoscopy explores the rectum and colon, or large bowel. For patients across Williamstown and regional Victoria, an endoscopy aims to provide valuable insights and guidance for ongoing care in a single session.

Our Endoscopy Services

Gastroscopy
During a gastroscopy, a surgeon uses a thin camera to inspect the oesophagus, stomach, and the first section of the small intestine. This procedure helps investigate issues such as reflux, nausea, unexplained anaemia, or upper abdominal pain, and may uncover ulcers or irritation within the lining.

Colonoscopy
A colonoscopy allows surgeons to carefully examine the colon and rectum for signs of disease or irregularity. It’s an essential method for bowel cancer detection, identifying polyps, and exploring symptoms like ongoing diarrhoea, rectal bleeding, or unexplained bowel changes. Over a million colonoscopies are performed annually in Australia.

Your Endoscopy Williamstown Questions Answered
When should I have an endoscopy?
The National Bowel Cancer Screening Program provides free home test kits for Australians aged 45 to 74, but anyone with worrying digestive symptoms should consult their doctor, who may recommend an endoscopy. Warning signs include pain in the abdomen, reflux, rectal bleeding, swallowing difficulties, changes in bowel habits, or unexplained weight loss.
How do I prepare for a gastroscopy?
Preparation steps can vary based on your scheduled time, current medications, and any dietary needs, so it’s important to follow the directions provided to you. Typically, you’ll need to avoid eating solid food for six hours and stop drinking liquids two hours prior to your procedure. Because sedation is used, you’ll need to attend with an accompanying adult and arrange transport home afterwards.
How do I prepare for a colonoscopy?
Before your colonoscopy, Dr Roshan Ariyaratnam will give you detailed preparation guidelines. Following these instructions properly is essential to allow a clear view of your bowel and its lining during the procedure. You may receive directions for standard, extended, or Colonolytely bowel preparation. Be sure to follow these steps exactly, attend with a responsible adult, and organise safe transport home, as you won’t be able to drive due to sedation.
Are there any other procedure options?
Sometimes, your doctor might suggest alternative steps before proceeding with an endoscopy, including:
- Lower bowel examination (sigmoidoscopy)
- Fecal occult blood test
- DNA stool test
- Non-invasive virtual colon examination
- Barium enema
However, endoscopy is the procedure that offers specialists the clearest view of your bowel, oesophagus, bowel lining, and other areas of concern. This also allows them to take biopsies, remove polyps, and identify changes that may point to conditions such as inflammatory bowel disease, ulcers, or colorectal cancer.
What are the risks and benefits of endoscopy?
While endoscopy carries minimal risk, possible complications include bleeding, bowel or organ perforation, or cardiorespiratory problems, with death being extremely rare. Still, the risk of not undergoing a needed endoscopy is often higher, as it may delay the identification and management of serious conditions.
