 If you had nothing you can continue as normal immediately

If you have had biopsies/tissue samples the results will be available in 6-8 weeks. These will not be available from the endoscopy department.

However, this may be sooner if you are on a fast track suspected cancer pathway. Once the consultant has the biopsy results they will write to you or you will be invited to a clinic appointment.

After your procedure

You may have some bloating or stomach cramps or a feeling of fullness due to the air we put in during the test. This usually settles within a few hours, if not peppermint tea and walking about may help.

You may notice some spotting of blood on the toilet and/or tissue which will settle.

If blue dye spray was used this may show up in bowel motions for 24 hours.

Things to watch out for:

  • Severe pain in the neck, chest or abdomen

Going home

If you have had throat spray you may make your own way home. You will be advised at what time you may have a drink and eat as normal. If you have had sedation it is essential that someone with transport comes to pick you up from the unit. You will need to be accompanied by a responsible adult and it is recommended that they stay with you at home for 12 hours after the procedure if sedation was used. When you get home, it is important to rest quietly for the remainder of the day. Sedation lasts longer than you think. 

For twenty-four hours following sedation you should not: 

  • Drive a car
  • Operate machinery
  • Drink alcohol
  • Sign any legally binding documents.

Following Entonox you must not drive until the endoscopist deems you fit enough, this is usually within 30 minutes.

If you feel unwell and do not have any of the above contact the ENDOSCOPY UNIT.

Follow up

Dependent on the nature of the finding you may need further investigations, these will be arranged by your referring clinician.
