Before The Outpatient Procedure:
Your doctor will give you complete instructions about the truFreeze spray cryotherapy procedure. Be sure to follow these directions. For instance, you’ll need to stop eating the evening before the procedure and some of your regular prescription medications may need to be adjusted. Do not change any medications unless specifically instructed to do so by your doctor. You should also arrange for someone to drive you home on the day of the procedure.
Just before the procedure, you’ll receive medication through an intravenous line to help you relax. Then, as you have experienced with other examinations, your doctor will insert an endoscope, followed by a special catheter through the endoscope. The light and camera on the endoscope allow your doctor to see a magnified view of the ablation area on a video monitor in the procedure room. Liquid nitrogen will be sprayed through the catheter onto the targeted tissue to freeze and destroy it. You won’t be able to feel the tissue being frozen.
The area being ablated will be frozen and thawed for a period of time as determined by your doctor. The cycle of freezing and thawing will be repeated several times. There may be more than one area to ablate, so the cycles may be repeated at different locations. The number of cycles and number of sites will be determined by your doctor.
After The Procedure:
When finished, you’ll be moved to a recovery area until you are fully awake. The clinical staff will review the discharge instructions with you, and when you’re ready, someone can drive you home.
Spray cryotherapy is often an outpatient procedure. If so, you will return home the same day and be able to resume eating a soft diet. Most patients resume their normal routine and diet the next day. You may feel some minor discomfort about 48 hours after the procedure. If needed your doctor can give you a prescription for this pain, should it occur. Occasionally patients experience post-therapy side effects such as chest pain, sore throat and difficult or painful swallowing, which are generally relieved by taking over-the-counter medication. The ablated tissue will continue to heal over the next few weeks. Your doctor will ask you to come back for a follow-up examination to assess your progress. If additional procedures are required, they will be scheduled at that time.
