Evaluation of the impact of a protocol for immediate vulvar reconstruction after vulvectomy.

Vulvar cancers are usually diagnosed at an advanced stage and require wide surgical resections in the form of vulvectomy. Immediate vulvar reconstruction can potentially reduce the reoperation rate and postoperative complications. With this objective, we introduced a protocol for immediate vulvar reconstruction. This study, five years after its introduction, assesses the impact of this intervention on the postoperative evolution of vulvectomy patients. In January 2017 we introduced a protocol for immediate vulvar reconstruction that considered four criteria of high risk for postoperative dehiscence. Patients who meet the criteria were reconstructed at the time of the vulvectomy. To assess the impact of the protocol, we prospectively registered all included patients over a 5 years period (2017-2022). As a control group, we reviewed the vulvectomised patients at our centre from January 2012 to January 2017 (5 years) who would have met the protocol. No statistically significant differences were found in the epidemiological data (age, diabetes mellitus diagnosis, and obesity diagnosis) or in the tumour characteristics (tumour size). We obtained a statistically significant difference in the incidence of complications and need for reintervention, in favour of the reconstruction group. Our study shows the medical and economic benefits for vulvar cancer patients of immediate vulvar reconstruction.

Vulvar cancer: surgical management and survival trends in a low resource setting.

BACKGROUND: This study aims to analyze risk factors, clinical profiles, treatment protocols, and disease outcomes in histologically proven resectable vulvar cancer (VC) patients according to tumor stage. This is a retrospective analysis of a prospectively collected database of 20 VC patients from May 2014 to June 2019. RESULTS: The mean age of VC diagnosis was 55 years, with a range of 38-84 years. The incidence was four cases per year. The disease incidence was significantly more in post-menopausal (65%) and multiparous (90%) women. According to FIGO staging of vulvar cancer, stages I, II, and III were assigned to 6, 1, and 11 patients respectively. Two patients suffered from stage IVa vulvar melanoma. All patients had undergone surgical interventions. Patients treated with only nonsurgical (chemotherapy/radiotherapy/chemo-radiotherapy) treatment modalities were excluded from the study. Fifteen patients were treated with wide local excision (WLE), bilateral inguinofemoral dissection (B/L IFLND), and primary repair. Four and one patients were treated with radical vulvectomy (RV) and modified radical vulvectomy (MRV) [with or without B/L IFLND and PLND] respectively. Reconstruction with V-Y gracilis myocutaneous and local rotation advancement V-Y fasciocutaneous flaps were done in two patients. Therapeutic groin nodal dissection was performed in 19 patients except in one patient who was treated by palliative radical vulvectomy. In the final histopathology reports, tumor size varies from 0.5 to 6.5 cm (mean 3.35 cm) with the predominance of squamous cell carcinoma (18 out of 20 patients). Only 10 out of 18 eligible patients received adjuvant treatment. Poor patient compliance has been one of the major reasons for adjuvant treatment attrition rate. Systemic and loco-regional metastasis occurred in 3 patients each arm respectively. Poor follow up of patients is the key limitation of our study. CONCLUSION: Vulvar cancer incidence was significantly high in post-menopausal and multiparous women. The most important prognostic factors were tumor stage and lymph node status. Oncological resection should be equated with functional outcome. The multidisciplinary team approach should be sought for this rare gynecological malignancy.

Evidence-based wound classification for vulvar surgery: Implications for risk adjustment.

OBJECTIVES: The correct wound classification for vulvar procedures (VP) is ambiguous according to current definitions, and infection rates are poorly described. We aimed to analyze rates of surgical site infection (SSI) in women who underwent VP to correctly categorize wound classification. METHODS: Patients who underwent VP for dysplasia or carcinoma were collected from the National Surgical Quality Improvement Program database (NSQIP). SSI rates of vulvar cases were compared to patients who underwent abdominal hysterectomy via laparotomy, stratified by the National Academy of Sciences wound classification. Descriptive analyses and trend tests of categorical variables were performed. RESULTS: Between 2008 and 2016, 2116 and 31,506 patients underwent a VP or TAH, respectively. Among VP, 1345 (63.6%), 364 (17.2%), and 407 (19.2%) women underwent simple vulvectomy, radical vulvectomy, or radical vulvectomy with lymphadenectomy, respectively. The overall rate of SSI for VP was higher than that observed for TAH (5.6% vs. 3.8%; p < 0.0001). While patients undergoing TAH displayed a corresponding increase in the rate of SSI with wound type (type I: 3.4%; type II: 3.8%, type III: 6.8%; type IV 10.6%; p < 0.001), no such correlation was observed for simple VP (type I: 3.3%, type II: 3.0%; type III: 3.2%; type IV: 0%; p = 0.40). On the other hand, a non-significant correlation was observed for radical VP (type I: 4.0%, type II: 10.1%; type III: 14.3%; type IV: 20.0%; p = 0.08). The overall rate of SSI in patients undergoing any radical VP was similar to patients undergoing hysterectomy with a type IV wound (10.1% vs 10.6%, p = 0.87). CONCLUSION: Patients undergoing VP are at high risk of infection. Simple vulvectomy should be classified as a type II and radical vulvectomy as a type III wound. These recommendations are important for proper risk adjustment.

Introducción y objetivo. La cirugía de vulvectomía se asocia a una gran incidencia de complicaciones de la herida quirúrgica que pueden evitarse mediante la reconstrucción inmediata de la vulva. En este trabajo buscamos presentar los resultados obtenidos en nuestro centro hospitalario mediante la introducción de un protocolo de reconstrucción inmediata tras vulvectomía. Material y método. En enero de 2017 se implantó en nuestro hospital un protocolo de reconstrucción inmediata tras vulvectomía con el fin de establecer una serie de criterios que permitan al ginecólogo detectar aquellas pacientes con alto riesgo de dehiscencia de la herida tras vulvectomía y contactar con el Servicio de Cirugía Plástica para coordinar la reconstrucción inmediata de la vulva. Durante un periodo de 18 meses registramos los datos de las pacientes sometidas a dicha intervención: edad, tipo de neoplasia, criterio reconstructivo, técnica reconstructiva, uni o bilateralidad, estancia hospitalaria y complicaciones en los 30 primeros días de postoperatorio. Resultados. Registramos un total de 9 pacientes sometidas a reconstrucción inmediata: 8 mediante colgajo en flor de loto y 1 mediante colgajo miocutáneo de gracilis. La estancia media hospitalaria fue de 31.4 días y 3 pacientes presentaron complicaciones postoperatorias en forma de dehiscencia de la herida quirúrgica. Conclusiones. Consideramos que nuestro protocolo es una herramienta adecuada para desarrollar una colaboración interdepartamental entre Ginecología y Cirugía Plástica y para implantar la reconstrucción vulvar inmediata

Background and objective. Vulvectomy surgery is associated with a high incidence of surgical wound complications that may be avoided with immediate vulvar reconstruction. In this paper we present the results obtained in our hospital with the implementation of an immediate vulvar reconstruction protocol. Methods. In January 2017 we established an immediate vulvar reconstruction protocol in our center with a list of criteria that would allow the gynecologist to detect those patients with a high risk of wound dehiscence after vulvectomy in order to coordinate the immediate reconstruction of the vulva with our Plastic Surgery Service. For the next 18 months, we recorded the information of those patients intervened: age, pathology, reconstructive criteria, reconstructive technique, laterality, hospital stay and complications during the first 30 postoperative days. Results. We performed immediate vulvar reconstruction in 9 patients: 8 with a lotus flap and 1 with a gracilis myocutaneous flap. Mean stay was 31.4 days and 3 patients developed complications in the form of surgical wound dehiscence. Conclusions. We consider that our protocol is a useful tool for the implantation of immediate vulvar reconstruction and to establish a collaboration between gynecologists and plastic surgeons

Pedicled neurocutaneous anterolateral thigh flap for groin reconstruction - A case report.

Several different flaps based on the feeding vessels of sensitive nerves have been described in the limbs. This article reports the case of a neurocutaneous flap based on the lateral femoral cutaneous nerve (LFCN), employed for reconstruction of an inguinal defect. A 61-years-old female patient had undergone vulvectomy and bilateral inguinal lymphadenectomy for vulvar cancer with postoperative left groin wound breakdown. After a 3 weeks negative pressure therapy course, she presented a 10 × 4 cm skin and subcutaneous defect with undermined edges in the left inguinal area. Reconstruction with 14 × 6 cm pedicled left anterolateral thigh flap was planned. After the dissection of the vascular pedicle and of the sensitive nerve, complete thrombosis of both the veins and arterial spasm of perforating pedicle was detected. As the flap color was good, and slow marginal bleeding was present, we inspected the small vessels surrounding the nerve that were pulsating. To confirm the vascularization coming from the neural pedicle, we clamped the perforator and performed intraoperative indocyanine green (ICG) fluorescence angiography that showed a good fluorescence of the flap with a proximal to distal pattern of progression. The flap was transferred on the neural pedicle, survived completely, and wounds healed normally. Three months after surgery, the patient underwent radiotherapy, with uneventful course. In her last follow-up, 2 years after surgery, patient was free of disease and the flap showed normal scarring. This is the first case reported of a pedicled neurocutaneous flap based on the LFCN, indicating that in case of unsuitable perforators it could be an alternative pedicle.

Trends and Complications of Vulvar Reconstruction After Vulvectomy: A Study of a Nationwide Cohort.

OBJECTIVES: The objective of this study was to determine complications associated with primary closure compared with reconstruction after vulvar excision and predisposing factors to these complications. METHODS: Patients undergoing vulvar excision with or without reconstruction from 2011 to 2015 were abstracted from the National Surgical Quality Improvement Program database. Common Procedural Terminology codes were used to characterize surgical procedures as vulvar excision alone or vulvar excision with reconstruction. Patient characteristics and 30-day outcomes were used to compare the 2 procedures. Descriptive and univariate statistics were performed. Adjusted odds ratios and confidence intervals were calculated using a logistic regression model to control for potential confounders. Two-sided α with P < 0.05 was designated as significant. RESULTS: A total of 2698 patients were identified; 78 (2.9%) underwent reconstruction. There were no differences in age, race, body mass index, diabetes, hypertension, tobacco use, heart failure, renal failure, or functional status between the 2 groups. American Society of Anesthesiologists class 3 and 4 patients and those with disseminated cancer were more likely to undergo reconstruction (both P < 0.001). On univariate analysis, reconstruction was associated with increased risk of readmission, surgical site infection, pulmonary complications, urinary tract infection, transfusion, deep venous thrombosis, sepsis, septic shock, unplanned reoperation, longer hospital stay, need for skilled nursing or subacute rehab on discharge, and death within 30 days. On logistic regression analysis, disseminated cancer, American Society of Anesthesiologists classes 3 and 4 and reconstruction remained significant risk factors for readmission and any postoperative complication. CONCLUSIONS: Patients undergoing vulvar excision with reconstruction are at increased risk for readmission and postoperative complications compared with those undergoing excision alone. Careful patient selection and efforts to optimize surgical readiness are needed to improve outcomes. Long-term data could help determine if these 30-day outcomes are a reliable measure of surgical quality in vulvar surgery.

Hyperbaric oxygen therapy as adjuvant for treating wound complications after extensive resection for vulvar malignancy.

INTRODUCTION: Necrosis, wound breakdown, and infection represent major complications associated with radical vulvectomy. We aimed to analyze the feasibility of hyperbaric oxygen (HBO2) therapy as an adjunctive treatment for such complications. METHODS: We performed a retrospective analysis of the medical records, clinical charts, and operative records of vulvar cancer patients who underwent hyperbaric oxygen therapy after extensive surgical resection in our institute between 2012 and 2016, with a comparison of the clinical outcomes of patients with similar surgical procedures andsevere wound complications who did not undergo HBO2. RESULTS: A total of 16 patients were included in the study. In the subgroup treated with HBO2, seven patients were identified. Two patients had primary surgery, while five had recurrent surgery (of these, two had previously undergone radiation therapy). Six patients received reconstructive flaps (five myocutaneous and onefasciocutaneous), while one patient had primary suture. Dehiscence, ischemia and necrosis were estimated to cover 30%-80% of the surgical surface area. Surgical debridement was performed in six patients. Daily 90-minute sessions in the hyperbaric chamber were performed at a pressure of 2.2 atmospheres absolute, with partial oxygen pressure of 1672 mbar. Infection control and satisfactory healing were achieved using 10-61 sessions. All patients in the subgroup who did not receive HBO2 required surgical debridement due to partial or near-total flap necrosis, with two reconstructive interventions required. CONCLUSIONS: Hyperbaric oxygen therapy was an efficient adjuvant for wound healing and infection control in managing wound complications after extensive vulvar resections.

Transient Reactive Eruptive Lymphangiectasia Following Partial Vulvectomy for Chronic Acquired Lymphangioma.

A 64-year-old white woman was originally diagnosed with histiocytic lymphoma in 1977. She had bilateral lymph node biopsies of the groin, chemotherapy, and radiation therapy after her diagnosis had been confirmed pathologically. She was treated with prednisone and vincristine.

The lymphatic superficial circumflex iliac vessels deep branch perforator flap: A new preventive approach to lower limb lymphedema after groin dissection-preliminary evidence.

OBJECTIVE: Groin dissection is the procedure with the highest risk of lower limb lymphedema.As lymph stasis causes irreversible alterations to the limb over time,therapies should be administered in early stages,or better yet, lymphatic drainage impairment should be prevented.We developed a new preventive approach to lymphedema after groin dissection, and we report our preliminary experience. PATIENTS AND METHODS: We enrolled 5 patients undergoing bilateral groin dissection for vulvar cancer. Preoperative study of lower limbs lymphatic function was obtained by lymphoscintigraphy, with lymphatic transport index, indocyanine green (ICG) lymphography, and volume measurement with lower extremity lymphedema (LEL) index calculation. At the end of lymphadenectomy, one groin was closed in the standard way. On the other side, a lymphatic flap pedicled on the distal perforator of the deep branch of the superficial circumflex iliac vessels, was transposed into the groin region. Lymphatic function examination of the limbs was repeated 6 months after surgery. RESULTS: Before surgery no patient showed lymphatic drainage impairment at lymphoscintigraphy or lymphography, LEL index was in every limb lower than 250 (mean: 217.3 ± 13.83). After surgery the limbs treated with the flap showed no pathological swelling, LEL-index < 250 (mean: 235.4 ± 13.069), linear pattern at lymphography, and normal lymphoscintigraphy. The untreated limbs showed from moderate to severe edema with 265 < LEL-index < 310 (mean: 283 ± 16.3), diffuse dermal backflow at lymphography and interruption of lymph flow, with dermal backflow, at lymphoscintigraphy. Mean difference between preoperative and postoperative volumes was 64.8 ± 25.1 in the untreated side and 19 ± 11.7 in the side with the flap. The difference between preoperative and postoperative volumes compared between the treated and untreated side was statistically significant (P < .01). CONCLUSION: Our preliminary evidence suggests that this flap can prevent lymphedema after groin dissection. Further studies are necessary to confirm these results.
