Gastroscopy involves a flexible endoscope which passes through the mouth of patients to the oesophagus, stomach and duodenum to examine if there is any inflammation, helicobacter pylori, peptic ulcer or tumor diseases. Biopsy and polypectomy will be performed during examination when necessary.


  • Preparation

  • Patients need to be fasted for 6 hours before the procedure.
  • Prior to the procedure, there will be a brief consultation to explain the procedure and the risks involved. A consent form will then be signed by the patient.

    The procedure

  • Please remove the denture, accessories and metallic objects
  • Doctor will spray local anaesthetics to the throat of patients before having intravenous sedation. The examination will start when the patient is asleep to alleviate any discomfort during the procedure.
  • The endoscopy will be passing through the mouth of patients to the oesophagus, stomach and duodenum.
  • The procedure will be completed within 5 to 10 minutes

    Rest after the procedure

    Personal resting suites are provided for patients to take a 15-30 minutes nap to wear off the sedation. Family members can accompany with the patient during the rest.


    Points to note after the procedure

  • As patient is sedated, he/she should be accompanied by family members.
  • The sedation and the anaesthetics may temporarily affect one's co-ordination and reasoning skills, therefore, avoid driving, drinking alcohol, making any important decision or signing legal document in 24 hours after the procedure.
