Direct Access Colonoscopy and Iron infusions

Our direct access endoscopy pathway allows for suitable patients to be referred directly for Colonoscopy and or Gastroscopy without prior consultation. All urgent indications are guaranteed to have a procedure within 30 days of referral in the public or private hospital system.

Indications: Positive FOBT, iron deficiency anaemia, GI bleeding (melaena or lower GI), family history of polyps or CRC and patients with previous polyps. Those with medical comorbidities, increased risks or unclear indications for scopes will need a review prior.

We provide direct access for iron infusions at HSS or at Westmead Public Hospital for suitable patients with low ferritin and intolerance/failure of oral iron supplements. All patients are given 1g of Ferinject, which takes as little as 15 minutes for an infusion.

For all direct access: Fax referalls to 8624 4769 or fill in the form here.

Saturday Morning Gastroscopy and Colonoscopy at HSS

From March, we will be offering one scope list per month on a Saturday morning for all the busy people who would find it more convenient to have their procedures on a weekend. This will only be at the Hospital for Specialist Surgery (HSS) Norwest. The scope lists will be performed by one of our Gastroenterologists on a rotating roster. There is no change to billing arrangements with all procedures No-Gap billed by the Gastroenterologist and Anaesthetist. Ask us about a Saturday morning scope at your next visit.

New Hepatitis C treatments available

We are now treating all patients with hepatitis C with oral, direct acting antivirals (DAAs) which have cure rates between 85-100% and none of the side-effects of interferon.
