  Abstract 

Vitiligo surgery is an effective method of treatment for selected, resistant vitiligo patches in patients with vitiligo. Physician's qualifications: The physician performing vitiligo surgery should have completed postgraduate training in dermatology which included training in vitiligo surgery. If the center for postgraduation does not provide education and training in cutaneous surgery, the training may be obtained at the surgical table (hands-on) under the supervision of an appropriately trained and experienced dermatosurgeon at a center that routinely performs the procedure. Training may also be obtained in dedicated workshops. In addition to the surgical techniques, training should include local anesthesia and emergency resuscitation and care. Facility: Vitiligo surgery can be performed safely in an outpatient day care dermatosurgical facility. The day care theater should be equipped with facilities for monitoring and handling emergencies. A plan for handling emergencies should be in place, with which all nursing staff should be familiar. Vitiligo grafting for extensive areas may need general anesthesia and full operation theater facility in a hospital setting and the presence of an anesthetist is recommended in such cases. Indications for vitiligo surgery : Surgery is indicated for stable vitiligo that does not respond to medical treatment. While there is no consensus on definitive parameters for stability, the Task Force suggests the absence of progression of disease for the past one year as a definition of stability. Test grafting may be performed in doubtful cases to detect stability. Preoperative counseling and Informed consent: A detailed consent form elaborating the procedure and possible complications should be signed by the patient. The patient should be informed of the nature of the disease and that the determination of stability is only a vague guide. The consent form should specifically state the limitations of the procedure, about the possible future progression of disease and whether more procedures will be needed for proper results. The patient should be provided with adequate opportunity to seek information through brochures and one-to-one discussions. The need for concomitant medical therapy should be emphasized and the patient should understand that proper results take time (a few months to a year). Preoperative laboratory studies include hemogram including platelet counts, bleeding and clotting time (or prothrombin and activated partial thromboplastin time), and blood chemistry profile. Screening for antibodies for hepatitis B surface antigen and HIV is recommended depending on individual requirements. Anesthesia: Lignocaine (2%) with or without adrenaline is generally used for anesthesia; infiltration and nerve block anesthesia are adequate in most cases. General anesthesia may be needed in patients with extensive lesions. Postoperative care: Proper postoperative immobilization and care are very important to obtain satisfactory results.

  Introduction Top


Vitiligo is a common acquired depigmentation disorder of great cosmetic importance. The basic pathogenesis of vitiligo or for any of the putative subsets of vitiligo, still remains unknown. The medical treatment of vitiligo is dependent upon the presence of a melanocyte reservoir and is effective in only 60-70% of the patients. Certain types of vitiligo do not respond well to medical treatment and resistant lesions do persist even in those who respond. In light of these limitations of medical treatment, surgical treatment of vitiligo was first proposed in the 1960s. Over the years, the concept of surgical treatment has been expanded to include surgical "biotherapies" such as autologous, cultured melanocyte transplantation. The disease has a major impact on the quality of life of patients, particularly the Indian population, in which there is a severe stigma attached to the disease, affecting the social and psychological aspects of the patients. Due to these effects, there is a considerable need for active treatment of this disease, in contrast to fair-skinned patients in whom the disease is less apparent.


  Rationale and Scope Top


As such, there are no uniformly acceptable measurement tools and indices for measurement of the efficacy of outcomes of the surgical modalities of vitiligo treatment. Assessment of quality of life and global assessment should be performed because the percentage of regimentation may not always be a good indicator of patient satisfaction. There is an urgent need for universally acceptable, objective, reproducible and easy-to-use measurements to evaluate the efficacy of surgical vitiligo studies. These guidelines provide minimal standards of care for various surgical methods of treatment of vitiligo, with a brief description of the procedures as well as their advantages and disadvantages.


  Physician's Qualifications Top


The physician performing vitiligo surgery should have completed postgraduate training in dermatology; he/she should also have had adequate training in vitiligo surgery during postgraduation. Alternatively, training in vitiligo surgery may be obtained on the surgical table (hands-on) under the supervision of an appropriately trained and experienced dermatological surgeon. The training may also be obtained in dedicated workshops. In addition to the surgical technique, training should include techniques in local anesthesia and emergency resuscitation and care.


  Facility Top


Vitiligo surgery can be performed safely in an outpatient day care dermatosurgical facility under local anesthesia. The day care theater should be equipped with facilities for monitoring and handling emergencies. A plan for handling emergencies should be in place with which all nursing staff should be familiar. Transplantation for extensive areas of vitiligo may need general anesthesia and in such cases, an operation theater facility in a hospital setting and the presence of an anesthetist are recommended.


  Indications for Surgery and Patient Selection Top


Surgery is indicated for all types of stable vitiligo including segmental, generalized and acrofacial types that do not respond to medical treatment. While there is no consensus on definitive parameters for stability, various recommendations suggest a period of disease inactivity ranging from six months to two years. The task force agrees on a year of disease inactivity as the cut-off period for defining stability (Level D). Test grafting may be performed in doubtful cases to detect stability. The choice of surgical intervention should be individualized according to the type of vitiligo, stability, localization of lesions and cost-effectiveness of the procedure. Patient counseling about the nature of the disease and about the fact that the determination of stability is only a rough guide is essential.


  Explanation for Stability Top


The outcome of surgery is good in stable lesions whereas unstable lesions respond poorly. Thus, the stability status of vitiligo is the single, most important prerequisite in case selection. However, despite many studies, there is no consensus regarding the minimum required period of stability. The recommended period of stability in different studies has varied from four months to three years. Most authors have suggested that vitiligo can be classified as being stable when there is no progression of old lesions and/or development of new lesions during the past one year. A set of objective criteria-the Vitiligo disease activity score (VIDA), was suggested by Njoo et al. (7) in 1999 to follow the progress of the patient. It is a 6-point scale on which the activity of the disease is evaluated by the appearance of new vitiligo lesions or the enlargement of preexisting lesions gauged during a period ranging from < 6 weeks to one year [Table 1]. The task force recommends that surgery for vitiligo should be performed only in patients with VIDA scores of -1 or 0 (Level D).

  2. Malakar S, Lahiri K. How unstable is the concept of stability in surgical repigmentation of vitiligo? Dermatology 2000; 201:182-3.


Considering the variety of opinions, it is preferable to take multiple factors during patient selection for vitiligo surgery into account.


  Parameters for Establishing Stability of Vitiligo Top


  1. History of progression : Absence of new lesions
  2. Extension of old lesions : No extension of old lesions
  3. Koebner phenomenon : Absence of Koebner phenomenon either based on history or by checking for experimentally induced vitiligo
  4. Mini-grafting test or test-grafting : The original test was proposed by Falabella et al . (1) to select patients with stable vitiligo who may respond to melanocyte transplantation. The test was considered positive if unequivocal repigmentation took place beyond 1 mm from the border of the implanted graft over a period of three months. Although this test has been considered as a gold standard for establishing the stability and success of repigmentation, doubts have been expressed over its utility. It has been seen that even when the minigraft test is positive, the disease itself may be unstable.

  Consensus Recommendation of the Taskforce on Stability Top


The available evidence is insufficient to recommend a single cut-off period to assess stability. To facilitate consensus on this issue, the task force attempts to provide a clear definition of stability-a patient reporting no new lesions, no progression of existing lesions, and absence of Koebner phenomenon during the past one year. Spontaneous repigmentation should be considered as a favorable sign for the transplantation procedure. A test graft may be considered whenever there is a doubt about the stability, or the patient is unable to give a clear history on stability. It needs to be stressed here that the treating physician should always consider each patient individually and exercise his/her judgment (LEVEL D).

2. The age of the patient for vitiligo surgery
: As such, no uniformly accepted opinion exists concerning the minimum age for surgery. Vitiligo surgery is generally performed under local anesthesia, which would be difficult in children. General anesthesia for vitiligo surgery in a young child poses unacceptable risks and the progress of the disease is difficult to predict in children. Hence, many dermatologists feel that surgical procedures should not be performed in children. However, studies have suggested that results of transplantation procedures were better in younger individuals than in older ones. Thus, no consensus exists in this aspect and physicians should exercise their judgment after taking all aspects of the individual patient into consideration. (LEVEL C)

  Preoperative Counseling and Informed Consent Top


Proper counseling is essential; the nature of the disease, procedure, expected outcome and possible complications should be clearly explained to the patient. The need for concomitant medical therapy should be emphasized. Patients should understand that proper results may take time to appear (few months to one year). The patient should be provided with adequate opportunity to seek information through brochures, computer presentations, and one-to-one discussions.

A detailed consent form (see appendix 1) describing the procedure and possible complications should be signed by the patient. The consent form should specifically state the limitations of the procedure, possible future disease progression and whether more procedures will be needed for optimal outcome.


  Anesthesia Top


The recipient site is locally anesthetized by infiltration of 2% xylocaine, the pain of which can be reduced by prior application of EMLA® cream applied under occlusion for 1-2 hours. Adrenaline should not be used on the recipient site as it makes the judgment of adequacy of the denudation to the required depth difficult. Tumescent anesthesia and nerve blocks may be used in larger areas. If grafting is planned for extensive areas, general anesthesia may be needed in a hospital setting. (LEVEL D)


  Methods of Surgical Modalities Top


Methods of surgical modalities for vitiligo include both tissue grafts and cellular grafts.


  Tissue Grafts Top


  1. Punch grafting: In this procedure, punch grafts (of 1.2-2.0 mm diameter) are taken from donor areas over the thighs, buttocks, postauricular areas/posterior earlobe or the medial aspect of the upper arm. These are grafted into recipient sites in stable vitiligo lesions, which are created by using punches 1-2 mm in diameter. To ensure a better fit, recipient punches are generally smaller by 0.5 mm than donor punches. Smaller sized grafts may be used to yield better cosmetic results.

    Sockets are created in the recipient area at a distance of 5-10 mm and the harvested grafts are placed in these sockets. This allows the perigraft spread of pigment to cover the surrounding depigmented skin, the extent of which varies according to the skin color and site of the treated patch (more on exposed sites). (LEVEL B)

Dressings are postoperatively placed to ensure immobili- zation, and may be removed in 24 hours to check for the displacement of the grafts. Grafts are taken up in 7-10 days after which phototherapy or treatment with topical steroid is started to ensure even spread of perigraft pigment.

Advantages : This is the easiest and least expensive method and may be used satisfactorily in all areas other than the nipples and the angle of the mouth, where involuntary muscle contraction may interfere with graft uptake. It is even suitable for 'difficult-to-treat' locations such as the fingers, toes, palms and soles, etc.

Disadvantages and complications : This method is not suitable for large lesions as uniform pigmentation may not always be achieved. Other important complications include cobblestoning and a polka dot appearance.

2. Suction blister epidermal grafting: This procedure consists of obtaining very thin skin grafts consisting of only the epidermis. A physiological split is made at the dermoepidermal junction by the application of prolonged suction at a negative pressure of -200 to -500 mm of Hg to the donor site. The recipient site is dermabraded by using either a manual or a motorized dermabrader, depending on the size and site of the lesion. Thin grafts are applied to the dermabraded recipient site. Alternatively, the recipient site may be denuded by an Erbium:YAG or carbon dioxide (CO 2 ) Laser. Equipment needed includes specially altered disposable syringes, suction cups or glass funnels, suction apparatus and manual/motorized dermabraders. The graft may fall off in a period of a week to ten days. (LEVEL B)

Advantages: It yields excellent cosmetic results as the graft is very thin. One of the major advantages of this procedure is that chances of scarring at the donor or recipient sites are minimal as the graft is purely epidermal.

Disadvantages : The major disadvantage of this procedure is that it is time-consuming as donor site blistering requires a few hours. Large areas can not be treated by this method.

  3. Pai GS, Vinod V, Joshi A. Efficacy of erbium: YAG Laser-assisted autologous epidermal grafting in vitiligo. J Eur Acad Dermatol Venereol 2002;16:604-6.


3. Split-thickness grafting: Split-thickness skin grafting involves the free transfer of the epidermis along with a portion of the dermis from one site to another. The procedure is carried out under local anesthesia (for localized lesions) or general anesthesia (for extensive lesions). It consists of obtaining very thin, split thickness skin grafts, consisting of the epidermis and a part of the upper papillary dermis, and grafting them on the denuded (dermabraded or Laser-abraded) recipient site. The grafts are further secured with pressure and immobilization. Motorized dermatomes such as Padgett's or Zimmer's dermatomes, may be used to obtain ultra-thin, split-thickness grafts, which may give cosmetically superior results compared to those with manual dermatomes (Level B) .

Instruments include dermabraders, skin-grafting knives such as the Humby's knife or any of its modifications, as well as other surgical instruments. Large areas can be grafted in a single sitting.

Advantages: This method has the advantage of treating a relatively large area in a short period of time.

Disadvantages : Taking split-thickness grafts of uniform thickness requires skill and experience. Other disadvantages include 'stuck-on' or 'tire patch' appearance, curling of the border with beaded appearance, color mismatch, milia, perigraft halo of depigmentation, and donor site scarring.

4. Other tissue grafting procedures : Several other methods of tissue grafting have been performed by different authors. These methods or their modifications may be used by the treating physician depending on individual expertise and experience. Hair follicle-grafting has been performed by a few authors for treating small patches in hair bearing areas and has been found useful in treating lesions with leukotrichia. A small strip of hair-bearing scalp is taken from the occipital area; single hairs are separated and transplanted into vitiligo patches 5-10 mm apart. (LEVEL C)

In flip-top grafting, superficial, thinly shaved biopsies that are 2-4 mm in size, are taken using a razor blade, which are then sectioned into smaller 1-2 mm grafts. A 5-mm flap of epidermis with minimal dermis is raised with a razor blade at the recipient site, and the grafts are placed under this flap. The major advantage of this procedure is that there is rapid healing and no cobblestoning. (LEVEL C)

  Cellular Grafts Top


These methods represent important recent advances and need specialized training and appropriate equipments. The following cellular grafting techniques have been advocated in the surgical management of vitiligo:

  1. Autologous, noncultured epidermal cell suspension
  2. Autologous, cultured melanocyte transplantation
  3. Autologous, cultured epithelial grafts


1) Transplantation of autologous, epidermal cell suspension (noncultured melanocyte grafting): In this procedure, a shave biopsy sample is taken with a dermatome. The skin sample is immersed in a trypsin solution, the epidermis separated from the dermis, and after some additional steps, a cellular suspension of keratinocytes and melanocytes is obtained, which is transplanted on the denuded recipient site. (LEVEL B)

Advantages : In comparison with other surgical methods, the basal layer suspension method has the advantage that a fairly large area can be treated with the donor-to-recipient expansion ratio ranging from 5-10 fold. (LEVEL B)

Disadvantages: Taking split-thickness grafts requires skill and experience. This technique requires a properly equipped laboratory and trained personnel.

  4. Olsson MJ, Juhlin L. Leucoderma treated by transplantation of a basal cell layer enriched suspension.Br J Dermatol 1998;138:644-8.


2) Transplantation of cultured autologous melanocytes: Melanocytes are cultured in vitro for 15-30 days by the addition of media and growth factors. Once sufficient numbers are present, melanocytes are detached from the culture plates and suspension is transplanted onto the denuded recipient area in a density of 1000-2000 melanocytes/mm 2 . The recipient area can be denuded by dermabrasion, CO 2 , or an Erbium:YAG Laser. (LEVEL B)

Advantages : The major advantage is that the procedure can treat unlimited areas; however, it is recommended that vitiligo involving > 30% of the body surface area should not be treated surgically as chances of success are minimal in such cases. (LEVEL D)

Disadvantages : There have been some safety concerns about the use of cultured autografts in vitiligo. 12-tetradecanoylphorbol 13-acetate (TPA) used in the culture medium is a tumor promoter, making its long-term safety a concern. But recent availability of TPA-free and serum-free media provide a solution to this problem. However, this method is expensive and requires a tissue culture laboratory setup.

3 ) Autologous cultured epithelial grafts: Cells are seeded in a medium that allows co-cultivation of keratinocytes and melanocytes. A few weeks later, a cultured epidermal sheet is obtained, released by dispase and attached to petrolatum gauze. The recipient site is prepared as described in the cultured melanocyte transplantation section and the gauze is applied on the recipient site and dressed. (LEVEL B)

Advantages: The major advantage is that cells are expanded in the cell culture to treat a large area.

Disadvantages: The technique requires special personnel and equipments and is expensive.

  Certain Special Methods of Treatment in Selected Situations Top


Tattooing has been recommended as a suitable method in the angle of the mouth. Dermabrasion and chemabrasion (with cauterants such as trichloroacetic acid/phenol) have been used in lesions on hairy areas to produce pigmentation as adjuvant to phototherapy. A 308-nm excimer Laser has been found to be successful in a few studies, with > 75% repigmentation occurring in about 30% of the patients; it is not effective in acral areas. (LEVEL C)

  Evidence-Based Practice Guidelines for Choice of Method Top


As already highlighted, there is no uniformly acceptable objective measurement tool to compare the surgical outcome of a given modality. Recently, an attempt has been made by the European Taskforce on vitiligo to define and assess the severity of vitiligo. A scoring system has also been suggested to evaluate the outcome of transplantation procedures in vitiligo, although it is mostly subjective and has not been validated for interobserver bias in a large sample size.

Similarly, all three cellular graft techniques (non-cultured epidermal cell suspension, cultured melanocytes and cultured epidermis) were found to be equally effective. However, in comparison to tissue grafts, cellular grafts showed slightly lower success rates. One explanation may be that cellular grafts are generally used to treat larger areas in comparison to tissue grafts. (LEVEL A)

When compared on the basis of adverse events, the highest incidence of adverse events was reported with punch grafting followed by split-thickness grafting and suction blister epidermal grafting. Cellular grafting was associated with the lowest number of adverse events.

Thus, the choice of the procedure is dependent upon the site, area, availability of infrastructure (for cellular grafts), expertise of the dermatological surgeon, cost of the procedure and the patient's preference [Table 2].


  Conclusion Top


Surgical methods of treatment for vitiligo constitute an important adjuvant for medical therapy. Proper case selection based on the determination of stability of the lesions is very important but no uniform criteria exist for the determination of stability. Hence, in an attempt to build consensus on this issue, the task force suggests the following definition of stability: a patient reporting no new lesions, no progression of existing lesions, and absence of Koebner phenomenon over the past one year. Above all, proper patient counseling about the nature of the disease and the surgery is essential. Recommendations for the choice of surgical method for different types, sites, and areas are shown in [Table 2] (Level D).
