Innervated island flaps in morphofunctional vulvar reconstruction

Perforator versus Non-Perforator Flap-Based Vulvoperineal Reconstruction-A Systematic Review and Meta-Analysis

BACKGROUND

Patients with advanced vulvoperineal cancer require a multidisciplinary treatment approach to ensure oncological safety, timely recovery, and the highest possible quality of life (QoL). Reconstructions in this region often lead to complications, affecting approximately 30% of patients. Flap design has evolved towards perforator-based approaches to reduce functional deficits and (donor site) complications, since they allow for the preservation of relevant anatomical structures. Next to their greater surgical challenge in elevation, their superiority over non-perforator-based approaches is still debated.

METHODS

To compare outcomes between perforator and non-perforator flaps in female vulvoperineal reconstruction, we conducted a systematic review of English-language studies published after 1980, including randomized controlled trials, cohort studies, and case series. Data on demographics and surgical outcomes were extracted and classified using the Clavien-Dindo classification. We used a random-effects meta-analysis to derive a pooled estimate of complication frequency (%) in patients who received at least one perforator flap and in patients who received non-perforator flaps.

RESULTS

Among 2576 screened studies, 49 met our inclusion criteria, encompassing 1840 patients. The overall short-term surgical complication rate was comparable in patients receiving a perforator (n = 276) or a non-perforator flap (n = 1564) reconstruction (p* > 0.05). There was a tendency towards fewer complications when using perforator flaps. The assessment of patients' QoL was scarce.

CONCLUSIONS

Vulvoperineal reconstruction using perforator flaps shows promising results compared with non-perforator flaps. There is a need for the assessment of its long-term outcomes and for a systematic evaluation of patient QoL to further demonstrate its benefit for affected patients.

The inguinal fold as a flaps bank: the inguinal fold island flap (IFI flap)

The aim of this article is to describe an island flap, harvested from the inguinal fold, which can be used for vulvar reconstruction: the inguinal fold island flap (IFI flap). IFI flap is indicated for reconstruction of defects of vaginal vestibule and labia minora and it could be raised bilaterally safeguarding regional symmetry and avoiding vaginal introitus or urethral distortion. This flap has been utilized to reconstruct defects after vulvar melanoma and squamous cell carcinoma resections and in one case to restore vaginal vestibule anatomy in a revision surgery in a transgender woman. IFI flap is an example of an "aesthetic/functional" reconstruction which could be proposed to younger patients too.

Experience with gluteal V-Y fasciocutaneous advancement flaps in vulvar reconstruction after oncological resection and a modification to the marking: Playing with tension lines

Many post-vulvectomy vulvar reconstruction solutions, using local fasciocutaneous flaps where possible, have been proposed. We report the use of V-Y advancement flaps from the gluteal fold in medium to large vulvar reconstructions and a simple modification we made to the technique in order to minimise wound-related complications. Between 2006 and 2016, 30 vulvar reconstructions were performed via a total of 59 flaps, 24 of which were raised using the proposed modification to the plasty design. Short- and long-term (24 months) follow-up data were analysed, postoperative flap sensitivity was tested, and any arising complications were recorded. The mean age of patients treated was 75.3 years (51-92 years). The mean monolateral defect dimensions were 7.5 × 4.7 × 2.8 cm. Minor complications were recorded in 23% of patients (14% of flaps). One case of ostial stenosis occurred. Micturition and ambulation recovery was rapid, and flap sensitivity was fully restored 24 months after reconstruction. Scars were well hidden by natural soft tissue folds. The outcomes in this case series confirm that the gluteal V-Y advancement fasciocutaneous flap is a useful and simple technique for reconstructing even large vulvar defects. It has a low functional and aesthetic impact and enables rapid return to autonomy. Moreover, the simple modification to the V-Y flap proposed, designed to reduce tension at the apical part of the wound, appears to reduce the complication rate.

Vulvar Reconstruction by Perforator Flaps: Algorithm for Flap Choice Based on the Topography of the Defect

OBJECTIVE

Many techniques have been proposed to reconstruct acquired vulvar defects. In our experience, every type of vulvar defect can be repaired with 2 pedicled flaps, namely, the pedicle deep inferior epigastric perforator (DIEP) flap and the lotus petal flap (LPF).

MATERIALS AND METHODS

We report our reconstructive algorithm for vulvar reconstruction, based on the topography of the defect, applied in 22 consecutive patients from 2000 to 2012. According to the proposed algorithm, DIEP flap and LPF (monolateral or bilateral type) can repair all kinds of wide vulvar defects. Surgical defects were classified as type I (IA and IB) and type II in relation to the anatomy of the defect.

RESULTS

No major complications were reported in our series. All patients reported satisfactory results, both functionally and aesthetically.

CONCLUSIONS

We propose an easy classification of acquired vulvar defects separating the ones consequent only to the vulvar resection, with preservation of vagina (type I), by the wider defects after vaginal and vulvar resection (type II); type I can be subclassified into defects consequent to half-vulvar resection (type IA) or to total vulvar resection (type IB). Type I defects (IA and IB) can be reconstructed with monolateral or bilateral LPF; in type II resections, we have a great wound that required more tissue to fill the pelvic dead space, so we prefer pedicle DIEP flap.

Reconstruction of the Vulva with Sensate Gluteal Fold Flaps

Backround and Aims: Soft-tissue reconstruction of the vulva following resection of malignancies is challenging. The function of perineal organs should be preserved and the reconstructed area should maintain an acceptable cosmetic appearance. Reconstruction with local flaps is usually sufficient in the primary phase after a radical vulvectomy. Numerous flaps have been designed for vulvar reconstruction usually based on circulation from the internal pudendal artery branches.

In this paper we introduce our modification of the gluteal fold V–Y advancement flap as a primary reconstruction after a radical vulvectomy.

Patients and Methods: Twenty-two patients were operated with a radical vulvectomy because of vulvar malignancies. The operation was primary in eight and secondary in 14 patients. The reconstruction of the vulva was performed in the same operation for each patient

Results: All flaps survived completely. Wound complications were registered in three patients. Late problems with urinary stream were corrected in two patients. A local recurrence of the malignancy was observed in six patients during the follow-up period.

Conclusions: Gluteal fold flap is easy to perform, has a low rate of complications and gives good functional results.

Even a large defect can be reconstructed reliably with this method. A gluteal fold V–Y advancement flap is sensate and our modification allows the flap to be transposed with lesser dissection as presented before.

Reconstruction of acquired perineovulvar defects: a proposal of sequence

Acquired perineovulvar defects are usually the result of excision of vulvar intraepithelial neoplasia (VIN) or invasive squamous cell carcinoma. Because both VIN and vulvar carcinoma have a tendency toward local recurrence, future reconstructive options should be reckoned with during treatment of the primary and all subsequent (pre-) malignant perineovulvar lesions. Hence, a proposal of sequence of reconstructive options for these defects is called for. In cases where local skin flaps suffice, these are preferably designed in such a fashion as not to sever the branches of the internal pudendal vascular system. In cases where either a pudendal thigh flap or an infragluteal flap may be used to close the perineovulvar defect, the pudendal thigh flap is to be preferred to preserve the infragluteal flap for future use. Only when these flaps no longer are available or sufficient to cover the defect should the gluteal thigh flap be applied. The use of myocutaneous flaps is rarely indicated to close isolated superficial perineovulvar defects.

Postablative reconstruction of vulvar defects with local fasciocutaneous flaps and superficial fascial system repair

INTRODUCTION

Postablative reconstruction of vulvar defects is a difficult challenge because of the functional, locational and cosmetic importance of this region. Local flaps carry a high incidence of delayed wound healing as local flaps may redistribute but not eliminate local wound tension. Repair of the superficial fascial system may avert local complications by minimising tension to the skin and increasing the initial biomechanical strength of wound. The aim of this study was to determine the clinical outcome of local fasciocutaneous flaps used for postablative reconstruction of vulvar defects in which the superficial fascial system was repaired.

METHODS

A retrospective analysis was conducted of patients with vulvar carcinoma in situ or vulvar carcinoma, who underwent ablation and immediate reconstruction with local fasciocutaneous flaps and superficial fascial system repair. Postoperative complications were recorded and clinical outcomes were evaluated.

RESULTS

Twelve of the 13 flaps healed primarily. Complications included 2 superficial wound infections, both of which were treated successfully with antibiotic therapy. One flap was complicated by minor wound dehiscence, which healed with conservative treatment.

DISCUSSION

Local fasciocutaneous flaps with superficial fascial system repair provide excellent design flexibility and can be designed and tailored to reconstruct postablative vulvar defects with good outcomes and minimal morbidity.

Análise do emprego de retalhos fasciocutâneos para reconstrução vulvar imediata

OBJETIVO: Analisar o emprego de técnicas de reconstrução imediata de vulva, pós-ressecção cirúrgica, com retalhos fasciocutâneos das faces medial e/ou posterior da coxa. MÉTODOS: Estudo de coorte transversal, retrospectivo, para análise do resultado da reconstrução cirúrgica imediata, com retalhos fasciocutâneos em nove pacientes submetidas à vulvectomia, no período de maio de 2009 a agosto de 2010. RESULTADOS: A média de idade foi 61 anos (variação 36 a 82 anos). Em 56% dos casos, o diagnóstico foi neoplasia intraepitelial vulvar (NIV) tipo usual. A vulvectomia radical foi realizada em 45% das pacientes, a vulvectomia simples em 33% e as ressecções amplas, em 22%. Foram confeccionados 11 retalhos fasciocutâneos, sendo 36,3% de transposições de retalho posterior de coxa, 18,2% de retalhos mediais de coxa, 18,2% de retalhos em avanço em V-Y, 18,2% de retalhos em avanço simples e 9,1% de rotação de retalho de região posterior de coxa. Não houve casos de perdas importantes dos retalhos confeccionados. CONCLUSÃO: Os retalhos fasciocutâneos de coxa são, atualmente, boas opções para a reconstrução imediata da vulva pós-ressecção oncológica devido à preservação da sensibilidade e da disponibilidade tecidual nas áreas doadoras. A associação do Cirurgião Plástico com o Ginecologista oferece tranquilidade às pacientes e determina bons resultados pós-operatórios.

Trans-pubic abdominal flap for reconstruction of the labia majora

A flap is described for recreation of the labia majora. The flap was designed for a young woman who developed vulvar squamous cell carcinoma in-situ after immunosuppression for treatment of juvenile rheumatoid arthritis. The patient underwent removal of the labia majora, and was reconstructed with a bi-lobed abdominal flap tunneled through the mons pubis. The flap produced a normal genital contour and has functioned well to seven years follow-up.

Vulvar reconstruction using a "V-Y" fascio-cutaneous gluteal flap: a valid reconstructive alternative in post-oncological loss of substance

OBJECTIVE

We will present our experience in vulvar reconstruction using a local fascio-cutaneous flap, in order to get an easier intra-operative management and a good post-operative outcome.

METHODS

Between May 2006 and December 2008, eight patients with vulvar carcinomas underwent a vulvar reconstruction, using a V-Y advancement flap of the gluteal fold. This fascio-cutaneous flap, based on the perforator vessels originated from the internal pudendal artery, was used for the reconstructive treatment of patients who had undergone a vulvectomy with medium-size defects.

RESULTS

All the 16 flaps prepared survived without major complications. Walking and sitting positions were restored in few post-operative days. Length of hospitalisation was 2-3 weeks. The flaps restored sensitivity few months after surgery. In no case the surgical scars needed being revised.

CONCLUSIONS

The follow-up results proved satisfactory in terms of patients' compliance and morphological results. The flap appeared to be thin, well vascularised and very flexible in its advancement. The post-operative follow-up is characterised by a rapid healing and a low incidence of short- and long-term complications.

[Oncological pelvic surgery from a gynecological perspective]

The established gynecological cancer operations are based on functional anatomy derived from the mature organism and on a model of radial progressive tumor permeation. Surgical treatment aims to resect the tumor with a metrically defined radial margin of tissue microscopically free of neoplastic or dysplastic disease. However, despite adequate surgical performance local tumor relapses still occur. In the presence of histopathological risk factors adjuvant radiation is therefore recommended which increases treatment-related morbidity. The Leipzig School of Radical Pelvic Surgery has developed new gynecological cancer operations from a different perspective on anatomy and local tumor spread. Tissue mapping is deduced by following the organism's development from the stage of tissue deposition to maturity (ontogenetic anatomy) to define permissive compartments for cancer permeation. The variants of mesometrial resection (TMMR, PMMR) and vulva field resection (VFR) achieve very high (>95%) local control rates in stages I and II cancer of the lower and middle female genital tract without adjuvant radiation. Laterally extended endopelvic resection (LEER) provides sustained tumor control even in locally advanced and recurrent disease as well as cancer of the distal vagina.

Use of deep inferior epigastric artery flaps for reconstruction of the female genitalia

Free skin grafts have been the most conventional choice for reconstructing the female genital area after excision of malignant tumours. However, some patients have developed scar contractures, or depressed deformities or ectropion of the mucosal membrane of the urethra or vagina. We discuss here the use of deep inferior epigastric artery (DIEA) flaps. Although the method leaves a scar in the abdominal region, it can be hidden by underwear. We have operated on six patients with satisfactory results.

Gluteal Fold V-Y Advancement Flap for Vulvar and Vaginal Reconstruction: A New Flap

BACKGROUND

Soft-tissue reconstruction following vulvar cancer resection is a difficult challenge because of the functional, locational, and cosmetic importance of this region. Although numerous flaps have been designed for vulvar reconstruction, each has its disadvantages.

METHODS

The authors introduce the gluteal fold fasciocutaneous V-Y advancement flap for vulvovaginoperineal reconstruction after vulva cancer resection. This flap is supplied by underlying fascial plexus derived from perforators of the internal pudendal artery and musculocutaneous perforators of underlying muscle. The sensory supply of this flap comes from the posterior cutaneous nerve of the thigh and the pudendal nerve. An axis of V-shaped triangular flap is aligned to the gluteal fold. A total of 17 flaps were performed in nine patients.

RESULTS

All flaps survived completely, with no complications except for small perineal wound disruption in three patients.

CONCLUSIONS

This flap is thin, reliable, sensate, easy to perform, and has matched local skin quality and concealed donor-site scar on the gluteal fold. In addition, it can cover large vulvovaginal defects because it can be advanced farther as a result of the character of the gluteal fold area. In our experience, the gluteal fold fasciocutaneous V-Y advancement flap has proven very useful for vulvar reconstruction, especially at the point of donor-site scar, flap thickness, and degree of flap advancement.

Flap algorithm in vulvar reconstruction after radical, extensive vulvectomy

The objective of this study was to assess the reconstructive options after radical, extensive vulvectomy; relate them to tumor characteristics; and select a choice of flaps able to correct every remaining defect. This study is a retrospective review of a 4-year experience with 31 flaps in 20 consecutive vulvar reconstructions. Three of the 31 flaps presented nonsignificant delayed healing at their tips and 3 other flaps developed a major breakdown related to an infection or an error in flap planning. According to the authors, the size of the defect is the main issue that must be taken into consideration during the establishment of reconstructive needs. Closure of vulvar defects is preferably performed using fasciocutaneous flaps, which are very reliable flaps and can be raised with different techniques to meet different needs. A flap is then chosen with the fewest potential complications. An algorithm has been thus established: Small to medium-size defects are closed with island V-Y flaps, island gluteal fold flaps, or pedicled pudendal thigh flaps. Among them, the island V-Y flap is the workhorse flap for vulvar reconstruction because of its versatility, reliability, and technical simplicity compared with its very low complication rate. If the vulvar defect is large and/or reaches the vulva-crural fold, V-Y flaps are also preferred to close these large and posteriorly extended excisions. If the vulvar defect is very large, extending both anteriorly and posteriorly, the use of a distally based, vertically oriented rectus abdominis muscle flap is recommended. Using this algorithm, immediate vulvar reconstruction with pedicled local or regional flaps can be performed easily and reliably.

Versatile lotus petal flap for vulvoperineal reconstruction after gynecological ablative surgery

OBJECTIVE

The objective of the present work was to assess the efficacy and complications of the use of the lotus petal flap in the vulvoperineal reconstruction among female patients treated for vulvar malignancies.

METHODS

Between December 2000 and April 2003, five patients underwent vulvoperineal reconstructions with the fasciocutaneous skin flaps elevated from gluteal folds immediately after vulvoperineal ablative surgeries at National Cancer Center Hospital, Tokyo, Japan.

RESULTS

The mean surface area of vulvoperineal tissue defects was 157.9 cm(2) (64.0-195.0 cm(2)), which could be filled completely by bilateral lotus petal flaps. The mean length of follow-up was 18 months (7-32 months). All flaps successfully survived without fatal necrosis. In postoperative follow-up, all patients had no complaint of pain and no abnormal sensation at the site of flap or at the donor site, and the lotus petal flap caused no severe damage to excretion, mobility of the hip, or the sensation in the vulvoperineal area. The gluteal fold could make the donor-site scar stand out in all patients.

CONCLUSION

The lotus petal flap is thought to be one of the most ideal reconstructive procedures for vulvoperineal region from various viewpoints of oncology, function, wound healing, and cosmetic surgery.

Immediate vulvar and vaginal reconstruction using the gluteal-fold flap: long-term results

The gluteal-fold flap was used to reconstruct vulvar and posterior vaginal wall defects in 40 patients. This is a fasciocutaneous, islanded flap based on the internal pudendal artery and vein perforators. The flap is robust and has the advantage of being away from the pathway of carcinoma spread. In addition it has minimal donor-site morbidity as the scar is hidden in a natural crease.

Anatomical reconstruction after vulvectomy

BACKGROUND

Vulvectomy is a disfiguring operation detrimental to self-esteem and female identity, but surgical techniques for anatomical reconstruction are not routinely performed.

CASES

Anatomical reconstruction of the vulva is illustrated in 1) a patient with superficial vulvectomy, 2) a patient with deep anterior vulvectomy, and 3) a patient with extended radical vulvectomy. Random skin flaps and axial-pattern skin flaps based on the deep external and the internal pudendal arteries were used. All patients had good postoperative results.

CONCLUSION

Established reconstructive procedures can be used to restore the labial folds, vestibulum, posterior commissure, and perineum. We advocate reconstruction of the anterior commissure with clitoral protrusion after superficial and deep vulvectomy.

The gluteal-fold flap for vulvar and buttock reconstruction: anatomic study and adjustment of flap volume

The ideal skin-flap reconstruction provides functional preservation and a good cosmetic outcome in both the reconstructed site and the donor site. Although various flaps are used for reconstruction of the vulvar and buttock region, there are disadvantages associated with each. In 1996, Yii and Niranjan reported the gluteal-fold flap for vulvar reconstruction. As presently used, this flap is bulky, particularly in obese patients or when used for hemilateral reconstruction. Thinning the flap has been considered impossible because of the obscurity of the blood supply. In the study presented here, the pedicle vessels of this flap were studied in eight cadavers; the authors found that the flap is nourished by a direct cutaneous system of the internal pudendal artery and vein. Accordingly, adjustment of the flap volume was believed to be possible, with the exception of the adipose tissue containing the pedicle vessels. The authors have since used 14 thinned flaps for seven vulvar, one vaginal, and two buttock defects in 10 patients. All flaps survived completely. Good functional and cosmetic results were achieved with hemilateral or bilateral flaps in vulvar or buttock reconstruction. In the buttock in particular, the usefulness of this flap for anal and pelvic-floor reconstruction was demonstrated. The scar at the donor site, concealed in the gluteal fold, was acceptable. The gluteal-fold flap is very useful for various vulvar and buttock reconstructions because it can be adjusted to the required volume.
