Warts
Warts are most common on the hands, feet or genitals. They are caused by HPV-infections and are commonly known as Verrucae Vulgaris.
Why should warts be treated quickly ?
1. When small, a wart is more easily removed.
2. When removed, a wart will no longer be the origin of further spread.
Prevention and service to patients …

Cosmetic lesions
Removing cosmetic skin lesions is becoming increasingly common as we all aspire to be attractive and stay youthful as we age.
Wouldn’t it be nice to improve your treatment modality for these lesions.
Family Physicians in General Practice
● My Patients have no Warts.
● I don’t treat Warts or Skin Lesions.
● I treat Warts with a variety of alternatives to Cryotherapy because of no Liquid Nitrogen available.
● I send my Patients to the Pharmacy.
● I send my Patients to the Dermatologist.
How do Dermatologists perform Wart/Skin Lesion Treatment ?
Dermatologists usually treat Warts and Skin Lesions by freezing this tissue.
Cryotherapy is Medical Practice.
called the golden standard for Skin Lesion Treatment in 7
What are the alternatives ?
HF-surgery and laser Disadvantages; • • • • Pain – Anaesthesia required Risk of collateral damage. Risk of depigmentation, mainly in darker skin Scars easily.
8
Why Cryotherapy ?
Literature confirms that Cryotherapy is the practical, fast and primary form of treatment for Warts. Preparation and follow-up care are minimal to non existent.
If correctly applied, it is well tolerated by children and adults.

Definition of cryotherapy “Cryotherapy is the controlled destruction of unwanted tissue by the precise application of extreme cold.”

7 to 10 days after the Treatment the scab will disintegrate.

The advantages of Cryotherapy
● Sterile procedure: No excision, no risk of infection.
● No pain treatment: no need for local anaesthetic. ● Fast procedure: Follow-up care not necessary. ● Safe: no damage from overenthusiastic use.
● Speed of operation.
● Excellent results.
20
Are these claims confirmed in daily practice?
● No blisters, no pain?
● Always good results?
● Will one or two treatments cure the lesion?
● Definitive result?
Cryotherapy
The success/result of Cryotherapy Treatment will depend on the level of the user’s expertise. What are the criteria for successful Treatment?

Osmose: Principle of Cell Preservation
At slow freezing rates cells are given time for self protection.
Slow freeze Fast thaw Cell Membrane Nucleus Intracellular fluid Extracellular fluid
Principle of Cell Destruction
Intracellular fluid freezes, tiny spiked shards of ice are formed, cell membranes rupture, which will be the cause of Cell Destruction .
Fast freeze Slow thaw Cell Membrane Nucleus Intracellular fluid Extracellular fluid
Effective cryonecrosis from -27°C
It is described extensively in literature that:
“rapid freezing to minus (-) 27°C and more will produce cryonecrosis in all human tissues”.
Why second freeze after 30 seconds?
When freezing is too slow, extracellular ice formation occurs, which has the effect of insulating cells and preserving them rather than the desired opposite.
Key criteria of cryonecrosis
• • • • Rapid freeze, slow unassisted thaw Fast lowering of the temperature from +37°C to -27°C TWO freezing cycles in ONE treatment session Enough freezing power should be available to reach the bottom of the wart.

Traditional Cryotherapy treatment
Application with a cotton bud soaked with Liquid Nitrogen 29
A hassle to store and to refill
30
No control of energy transmission Cotton buds will rapidly lose energy
No control over temperature No control over energy = No control over temperature
No Control Over Penetration Depth
If there is insufficient freezing power available, with the forming layers of ice that hinder penetration, the lower levels of the lesion will not be reached.
No control over the inclusion zone
Cotton buds never fit well to the lesion resulting in inevitable inclusion of normal healthy tissue resulting in pain and blisters.
34
Definition of Cryotherapy

It will not bring control over the criteria essential for successful treatment with cryotherapy.
By spraying Cryogen onto the tissue, the application will become profiles.

with significantly better control over those parameters known for good treatment
Cryotherapy with N 2 spray
In hospital settings, Dermatologists sometimes use LN pumps for direct application of Liquid Nitrogen onto the tissue 37
Cryotherapy with N 2 spray
• • Better control over temperature Better control over energy supply However : Minimal treatment zone : 10mm & more.
The result is collateral damage and pain in all lesions smaller than 10mm. ● You still need Liquid Nitrogen, which is not always easy to have in out-patient situations 38
Analysis of the traditional methods and how they can be improved
With traditional cryotherapy methods, pain due to collateral tissue damage is not easy to avoid. Because of the pain experienced, patients will not allow for treatment long enough to penetrate deep enough, which leads to repeat visits.

Pinpoint Precision to the millimeter.
No treatment of healthy skin. No pain.
Patients will allow longer treatment with deeper penetration of freezing power.
Time consuming repeat visits will reduce dramatically!

Practical/Technical Aspects Freezing Rate: 1 mm per 5 seconds.
Maximum penetration: From 4 to 7 mm

Healing is complete after 3 to 6 weeks.
52
Cryotherapy in daily practice
For the first time cryotherapy is accurate to the millimeter.
No Collateral Damage = No pain.
The moment pain is experienced the freezing has reached the caudal extent of the lesion. At this moment the treatment will stop.
The operator can now evaluate the depth of treatment by feedback of the patient.
