Electrosurgery for the Skin - Article
ABSTRACT: The purposes of electrosurgery are to destroy benign and malignant lesions, control bleeding, and cut or excise tissue. The major modalities in electrosurgery are electrodesiccation, fulguration, electrocoagulation, and electrosection. Electrosurgery can be used for incisional techniques that produce full-thickness excision of nevi, for shave techniques that produce partial-thickness removal of superficial lesions, and for removing vascular lesions such as hemangiomas or pyogenic granulomas. The correct output power can be determined by starting low and increasing the power until the desired outcome is attained (destruction, coagulation, or cutting). Smaller cherry angiomas can be electrocoagulated lightly. Larger cherry angiomas may be easier to treat by shaving them first, then electrocoagulating or desiccating the base. The elevated portion of pyogenic granulomas can be shaved off with a scalpel or a loop electrode using a cutting/coagulation current. The base of the lesion is curetted to remove the remaining tissue and then electrodesiccated. Complications such as burns, shocks, and transmission of infection can be prevented by careful use of the electrosurgical equipment.
Management of Genital Warts - Article
ABSTRACT: Genital warts caused by human papillomavirus infection are encountered commonly in primary care. Evidence guiding treatment selection is limited, but treatment guidelines recently have changed. Biopsy, viral typing, acetowhite staining, and other diagnostic measures are not routinely required. The goal of treatment is clearance of visible warts; some evidence exists that treatment reduces infectivity, but there is no evidence that treatment reduces the incidence of cervical and genital cancer. The choice of therapy is based on the number, size, site, and morphology of lesions, as well as patient preferences, cost, convenience, adverse effects, and clinician experience. Patient-applied therapy such as imiquimod cream or podofilox is increasingly recommended. Podofilox, imiquimod, surgical excision, and cryotherapy are the most convenient and effective options. Fluorouracil and interferon are no longer recommended for routine use. The cost per successful treatment course is approximately dollars 200 to dollars 300 for podofilox, cryotherapy, electrodesiccation, surgical excision, laser treatment, and the loop electrosurgical excision procedure.
Dermal Electrosurgical Shave Excision - Article
ABSTRACT: The dermal electrosurgical shave excision is a fast and inexpensive method of removing epidermal and dermal lesions. The procedure is ideally suited for pedunculated lesions raised above the level of the surrounding skin. It consists of repetitive, unidirectional, horizontal slicing of a cutaneous lesion with a no. 15 blade followed by electrosurgical feathering to smooth out the wound edges. A smoke evacuator is used during electrosurgery to prevent inhalation of heat-disseminated viral particles. The procedure is followed by histologic evaluation of the shaved specimen. Suspicious pigmented lesions should not be shaved because the long-term prognosis of a malignancy may depend on the thickness of the lesion on histologic analysis. Administration of adequate local anesthesia should make this a painless procedure. Basic general surgery skills are required, and formal training in electrosurgery is highly recommended.
