What is serial excision?
As the word, 'serial' indicates this is a technique carried out in stages. It involves removal of a part of the lesion and closure of the wound edges.
Due to the excision, the skin, and tissues surrounding the lesion stretch with the passage of time. This adaptive laxity allows the remaining part of the lesion to be removed at a later date.
Which is the type of lesion which is amenable to serial excision?
These include wide lesions like naevi (moles), scars, tattoos and, other benign conditions of the skin.
How is serial excision done?
A consultation helps in assessment of the lesion and to know if you are a right candidate for serial excision. After examination, the surgeon will be to tell the approximate number of sessions required for complete removal of the lesion. In adults, serial excision is usually carried out under local anesthesia with or without sedation. Patients are discharged after the procedure. Dressing changes and suture removal are done during the follow-up visits. Physical therapy in the form of massage and ultrasound therapy may be advised in certain cases. Another session of excision is scheduled once the tissues have developed adequate laxity on clinical examination.
Who is a right candidate for serial excision?
These include individuals with:
- Wide benign skin conditions amenable to staged removal.
- Patients who prefer multiple small procedures instead of a single procedure which can result in additional scars.
- Individuals in good health without any serious co-morbid conditions.
- Those who would be compliant with the postoperative instructions and follow-up.
What are the advantages of serial excision?
They would include the following:
- Ability to treat wide lesions such as scars or nevus without the recruitment of distant or regional tissues.
- Scars remain confined to the area of the lesion.
- A simple technique which can usually be carried out as an outpatient procedure.
