Colorectal Surgery outpatient service in CALHN

The Central Adelaide Colorectal Surgical Units of the Royal Adelaide Hospital (RAH) and The Queen Elizabeth Hospital (TQEH) provides inpatient and outpatient services for patients living in the Central Adelaide Local Health Network area who suffer from colorectal surgical disorders as well as a tertiary referral service for complex colorectal conditions from both South Australia and interstate.

Services are also provided to patients referred from rural and remote areas.

Children aged less than 18 years of age are usually managed by paediatric surgeons with referral to the Women’s and Children’s Hospital. For those between the ages of 15 and 18 years, discussion with both adult and paediatric surgeons may be appropriate to determine the most appropriate referral pathway.
