- bleeding after a biopsy, if performed
- an allergic reaction to the sedative or throat spray
- perforation (tearing) of the stomach with the instrument (this is a serious but extremely rare complication).
Before the procedure
Full information will be sent to you to read in advance, but in short: you will be asked not to eat anything from six hours before the procedure and you may need to stop some of your medications on the day of the procedure. You will have the chance to ask questions of the nurse and doctor beforehand if you wish.
You will stay in the day stay unit until the sedation has worn off which usually takes 1-2 hours. You will be given something light to eat and drink before you go home. If you have been sedated, you are not to drive until the following day.
You will be given a full written report and explanation before you return home. If biopsies are taken these will be sent for analysis and results are available in approximately 10 days. A report and copies of these are sent to your GP.
