Minimally Invasive Procedures

Choose smarter treatment options designed to limit disruption to your daily life.

Colonoscopy

Please follow the instructions given by the hospital. This will ensure you have a clean bowel prep, as this helps with examination of your bowel when there is no stool to obstruct good vision.

Bowel Prep, the Day Before

  • Clear fluids – > 1 cup per hour
  • Picoprep at 3pm and 6pm
  • Nothing to eat/drink 6 hours prior to arrival in hospital

Risks of Colonoscopy

  • 1:1000 Perforation, requiring operation
  • Removing polyps increases risk of perforation
  • Bleeding, especially if there is removal of polyps or banding of haemorrhoids.

Post Colonoscopy Care

  • Do not drink alcohol, smoke, drive, operate machinery or sign any legally binding documents for the full 24 hours.
  • You must have someone to take you home and stay with you overnight
  • It is advisable that you rest for the remainder of the day, giving yourself time to recover from the procedure. The following day, you can return to your normal activities.
  • It is not unusual to experience some discomfort in your lower abdomen, this is from the air put inside the bowel to inflate it during the procedure. These wind-type pains and bloating usually pass and settle within a few hours. Try to pass wind as this will help.
  • If you have any concern, please contact the number above (during business hours), or present yourself to the emergency department of Hawkesbury hospital.
  • It takes 1 week for the results of any tissue removed to come back. Please follow up to check on the results and make further plans for a repeat colonoscopy.

Endoscopy

Patient Instructions After an Upper GI Endoscopy

You may feel bloated after the procedure. This is from air introduced during the examination and should go away quickly. Your throat may be slightly sore, but this will wear off.

You can resume eating a normal diet unless the doctor today advises otherwise.

Sedation will affect your judgment for about 24 hours. For your own safety and in some cases legally:


  • Do not drink alcohol, smoke, drive, operate machinery or sign any legally binding documents for the full 24 hours
  • Do not do activities that require coordination or balance for 24 hours
  • You must have someone to take you home and stay with you overnight
  • It is advisable that you rest for the remainder of the day, giving yourself time to recover from the procedure. The following day, you can return to your normal activities.

Seek Medical Advice from your GP or the Hospital if you

notice any of the following:


  • Have trouble swallowing
  • Sharp pain in the throat, chest or stomach or begin vomiting with or without blood
  • Have a high temperature or fever >38oC
  • Have redness, pain or swelling for more than 48 hours where you had the injection for sedation (hand or arm)
  • Any symptoms that you think is related to today’s procedure and is causing you serious concern

If you have any questions regarding the above instructions, please call your GP or hospital.
