Name of the Procedure:

Destruction of Premalignant Lesions (e.g., Laser Surgery, Electrosurgery, Cryosurgery, Chemosurgery, Surgical Curettement)

Summary

The destruction of premalignant lesions involves the removal of abnormal skin growths, such as actinic keratoses, using various methods like laser surgery, electrosurgery, cryosurgery, chemosurgery, or surgical curettement. These techniques aim to destroy 15 or more lesions in one session.

Purpose

This procedure targets the removal of premalignant lesions, which have the potential to develop into skin cancer. The primary goal is to eliminate these lesions to prevent malignant transformation and to improve the appearance of the skin.

Indications

• Presence of 15 or more premalignant lesions, such as actinic keratoses
• Lesions that are symptomatic, persistent, or cosmetically concerning
• Patients with high risk of skin cancer development

Preparation

• Follow doctor's instructions, which might include fasting or adjusting medications.
• Avoid sun exposure before the procedure.
• Diagnostic assessments may include skin exams and biopsies if necessary.

Procedure Description

1. The procedure begins with a sterile preparation of the affected area.
2. The specific method of destruction is chosen based on the type of lesions:
   • Laser Surgery: Focused beams of light are used to destroy the lesion.
   • Electrosurgery: Electric currents coagulate the lesion.
   • Cryosurgery: Liquid nitrogen freezes and destroys the lesion.
   • Chemosurgery: Chemical agents are applied to eliminate the lesion.
   • Surgical Curettement: A curette is used to scrape off the lesion.
3. Local anesthesia is administered to minimize pain.
4. The destruction process is performed for all identified lesions.
5. Post-procedure dressing and care instructions are provided.

Duration

The procedure typically takes 30 to 60 minutes, depending on the number of lesions and method used.

Setting

• Outpatient clinic or dermatology office
• Some cases may be conducted in a hospital or surgical center

Personnel

• Dermatologist or specialized surgeon
• Supporting nursing staff
• Anesthesiologist if needed for certain anesthesia levels

Risks and Complications

• Common: Pain, redness, swelling, blistering, temporary skin discoloration
• Rare: Infection, scarring, changes in skin texture, incomplete lesion removal

Benefits

• Reduces the risk of skin cancer by eliminating premalignant lesions
• Cosmetic improvement of skin appearance
• Benefits are typically observed within a few weeks post-procedure

Recovery

• Follow specific care instructions, including wound care and sun protection.
• Mild discomfort and redness may persist for a few days.
• Limit strenuous activities until the treated area heals.
• Follow-up appointments to assess healing and treatment effectiveness.

Alternatives

• Topical treatments (e.g., imiquimod, 5-fluorouracil)
• Photodynamic therapy
• Observation and regular monitoring for changes in lesions Each alternative has its own set of advantages and drawbacks compared to destruction techniques, such as being less invasive or requiring multiple sessions.

Patient Experience

During the procedure, patients may feel a mild stinging or burning sensation. After the procedure, some discomfort, redness, and swelling are common. Pain management includes over-the-counter pain relievers and cold packs. Comfort measures and proper wound care instructions are provided to support healing and recovery.
