The Combined Pedicled Anterolateral Thigh and Vastus Lateralis Flap as Filler for Complex Perineal Defects

Fournier's Gangrene Surgical Reconstruction: A Systematic Review

Fournier's gangrene (FG) is a rare form of necrotizing fasciitis of the perineal, genital, or perianal region. It is characterized by an aggressive course and high mortality rate, over 20%. FG demands immediate treatment including resuscitation maneuvers, intravenous antibiotic therapy and early surgical debridement. Background/Objectives: The gold-standard treatment for FG is surgical reconstruction. However, up to date, no precise guidelines exist. Thus, we decided to systematically review the literature, focusing on FG contemporary approaches to reconstructive surgery, aiming to analyze the various reconstructive strategies and their specific indications. Methods: A systematic review was carried out according to the PRISMA statement by searching various databases from April 2014 to April 2024, using the terms ''Fournier Gangrene OR Fournier Gangrene Reconstruction OR Fournier Gangrene Treatment OR Fournier Gangrene Plastic Surgery OR Necrotizing Fasciitis OR Necrotizing Fasciitis AND Reconstruction". The eligibility criteria included original studies aimed at discussing FG reconstruction with at least three clinical cases. Results: The final synthesis included 38 articles, and 576 reconstructions were described. Of these, 77.6% were minimally invasive strategies (direct closure, secondary healing, grafts, and local random flaps), while more invasive reconstructions (loco-regional flaps based on known vascular anatomy) were adopted in 22.4%. No free flaps were reported. Conclusions: FG requires immediate medical interventions including broad-spectrum antibiotic therapy, surgical debridement, adjuvant therapies, and reconstructive surgeries. Taking into account the anatomical characteristics of the inguinal-crural region, skin grafts and local random flaps could offer versatile and effective reconstructions for most FG cases, while the more invasive strategies should be reserved for very few cases. Future research is warranted to define an FG dedicated reconstruction protocol.

Lymphatic flow through (LyFT) ALT flap: an original solution to reconstruct soft tissue loss with lymphatic leakage or lower limb lymphedema

INTRODUCTION

The lympho-venous shunt using the distal vein of ALT flap pedicle allowed at the same time the coverage of the inguinal defects and to perform lymphovenous shunt into a run-in vein of the descending branch of the lateral circumflex femoral pedicle, draining the lymph through the flap pedicle. Surgical technique, complications and final outcomes (both clinical and lymphoscintigraphic) are reported.

METHODS

Five patients (45.8 y.o.[22-70]) with groin soft tissue loss with lymphatic leakage or lower limb lymphedema, benefited of the described technique. The ALT flap was used to cover the defect and, at the same time, we could perform a lymphovenous shunt between afferent lymphatics to the thigh and the descending branch of the lateral circumflex femoral pedicle, distal to the perforator nourishing the flap. Clinical and lymphoscintigraphic assessment of the limbs, cease of lymphorrhea or cellulitis/lymphangitis episodes, eventual downstaging of physiologic/physical therapy were recorded. LYMphatic Quality Of Life in leg (LYMQoLLeg) and patient satisfaction were evaluated.

RESULTS

Average flap size was 88.8cm² (range 84-126). The mean number of multi-lymphovenous anastomosis (MLVA) performed was 1.8 (range 1-3) per patient with 1-3 lymphatics shunted into each vein. Only one hemato-seroma requiring surgical revision. Mean improvement of perometer values was 48.2% (range 27.7-67.7) with an average follow-up of 13.6 months (range 12-17). Lymphoscintigraphy showed disappearing of the lymphatic leak and lymphedema with a high satisfaction of LYMQoL score.

DISCUSSION

The combination of pedicle flap with lympho-venous bypass as lymphatic derivation concept, improving the chronic morbidity scenarios of lymphatic complications.

A V–Y fasciocutaneous flap for perineal reconstruction following abdominoperineal resection: quicker and better than a myocutaneous gluteal flap?

Background

Abdominoperineal resection in patients with anorectal malignancies may require flap reconstruction for large perineal defects as an adjunct to the oncologic surgery. Perineal reconstruction should be timely, safe, and yield good long-term functional results. There is no agreement on the ideal approach.

Methods

We performed a retrospective observational cohort study to compare clinical outcomes and post-operative complications between a musculocutaneous gluteal flap and a fasciocutaneous V–Y flap for perineal reconstruction. We included all patients who underwent abdominoperineal resection at Karolinska University Hospital between 2016 and 2019. Patient demographics and comorbidities, as well as treatment data, post-operative complications, and follow-up data, were collected from medical records.

Results

A total of 44 patients were included with a mean age of 65 years where 73% were men. Reconstruction was made with a musculocutaneous gluteal flap in 19 patients (43%) and with a fasciocutaneous V–Y flap in 25 patients (57%). Flap-related post-operative complications occurred in 39% of the patients and the incidence did not differ between the groups (p = 0.831). Neither operative time, time to ambulant mobility, time to drain removal, nor time to epidural removal differed between the groups (p > 0.05). Four patients in the gluteal flap group and one patient in the V–Y flap group presented with long-term complications.

Conclusions

Post-operative complications are common after perineal reconstruction following abdominoperineal resection regardless of reconstructive approach. Our study confirms that both a fasciocutaneous and a musculocutaneous flap are acceptable options for perineal reconstruction.

Level of evidence: Level III, risk/prognostic study.

Impact of etiology leading to abdominoperineal resection with anterolateral thigh flap reconstruction: A retrospective cohort study

BACKGROUND

Large and deep perineal defects following abdominal perineal resection (APR) are a challenge for reconstructive surgeons. Even if generally performed for oncological reasons, APR can be indicated as well in extended infection-related debridement for Hidradenitis suppurativa, Fournier's gangrene, or Crohn's disease. We aimed to compare the outcomes of two groups of patients with different indications for APR (infectious vs. oncological) after pedicled anterolateral thigh (ALT) flap coverage RESULTS: Forty-four consecutive pedicled ALT flap used for coverage after APR in 40 patients were analyzed. 26 patients (65%) underwent APR for oncological reasons and 14 patients (35%) for infectious reasons. The overall postoperative complications rate was significantly higher for infectious cases (76.5% vs. 40.7%, p = 0.0304). Major complications occurred in 52.9% of infectious cases versus 11.1% of oncological cases (p = 0.0045). Obesity and infectious etiology were independent risk factors for overall and major complications, respectively.

CONCLUSION

Patients undergoing APR for acute or chronic infections had significantly more overall and major complications than patients having oncological APR. Modified care might be considered, especially in obese patients, in terms of surgical debridement, antibiotic treatment modalities, and postoperative management.

[Coverage of an infected Deep femoral arteria vascular graft bypass by pediculated chimeric antero- lateral thigh flap associated with a vastus lateral muscle]

Scarpa triangle defects with exposure of femoral bypass are challenging to treat. The authors present the case of a 46 years-old male with a groin defect of 10×18cm with an exposure on 5cm of an allograft of the deep femoral artery. Bypass was performed in emergency because of a limb ischemia with deep femoral artery thrombosis and aneurysm of the superficial femoral artery. The reconstructive surgery may propose a large musculo-cutaneous flap to fill the dead spaces surrounding the infected bypass, the flap should be vascularized by the deep femoral arteria, could not be the rectus abdominals flap because of the precedent abdominal incision. The homolateral pediculated ALT-flap with vastus lateral component appeared to be a good solution because of its versatility and the low morbidity of the donor site.

The “Sombrero-Shape” Super-Thin Pedicled ALT Flap for Complete Scrotal Reconstruction Following Fournier's Gangrene

When the scrotal sac is entirely debrided following a Fournier gangrene, testes exposure poses unique challenges for the reconstructive surgeon. Despite the anterolateral thigh (ALT) flap is considered a workhorse in such context, aesthetic results are often suboptimal because of the lack of natural ptosis and patchwork appearance. We describe the use of a super-thin pedicled ALT flap for total scrotal reconstruction, modified according to a peculiar flap design and inset technique. A 42-year-old man was referred to our department for delayed total scrotal reconstruction 8 months after a Fournier gangrene extensive debridement. A super-thin pedicled ALT flap from the right thigh was designed: in the central portion of the ALT, a lateral skin paddle extension was marked to guarantee adequate posterior anchorage during insetting and ptosis of the scrotal sac. This particular flap arrangement has inspired the name “sombrero” as the shape is akin to the famous hat. No secondary refinements were needed, and the patient showed satisfying aesthetic and functional results at 12 months' follow-up. The ALT flap design “sombrero” modification proposed in this article can improve scrotum cosmesis and patient satisfaction in a single-stage single-flap procedure.

Outcomes of the Composite Anterolateral Thigh Flap for Perineal Reconstruction After Postoncological Abdominoperineal Resection

BACKGROUND

The vertical rectus abdominis flap is considered the gold standard in perineal reconstruction after oncological abdominoperineal resection; however, it has a nonnegligible donor site morbidity. The anterolateral thigh flap offers reliable soft tissue coverage.

OBJECTIVE

The aim was to analyze long-term outcomes of composite anterolateral thigh-vastus lateralis flaps in oncological abdominoperineal resections.

DESIGN

We conducted a retrospective cohort analysis of a prospectively maintained database.

SETTINGS

This study was conducted in the Lausanne University Hospital. Annually, approximately 10 oncological abdomioperineal resections are performed. Literature reports 7% to 20% of patients undergoing abdominoperineal resection require flap reconstruction; in our institution, approximately 2 patients with large defects after abdominoperineal resections required reconstruction.

PATIENTS

Twenty-nine pedicled anterolateral thigh-vastus lateralis flaps in 27 consecutive patients (mean age 63 years +/-11.2, 23 with radiochemotherapy) after abdominoperineal resection to cover large defects (median 190 cm2, 48-600 cm2) were analyzed.

INTERVENTION

Pedicled composite anterolateral thigh-vastus lateralis flaps were performed after oncological abdominoperineal resection.

MAIN OUTCOME MEASURES

Descriptive statistical analysis was conducted. Short- and long-term outcomes were analyzed, univariate and multivariate analyses were performed. Median follow-up was 16 months (12-48 months).

RESULTS

Flap-related postoperative complications occurred in 16 flaps; flap-survival was 100%. Multivariate logistic analysis identified initial defect size as predictive for complications. Patients with larger defects (≥ 190 cm2) had higher complication rates (p = 0.006). Long-term analysis revealed 3 chronic fistulae, 2 tumor recurrences, 1 flap dysesthesia, and one perineal acne inversa.

LIMITATIONS

Limitations include retrospective analysis, selection bias, and lacking a control group. Sample size limits statistical power.

CONCLUSIONS

The pedicled anterolateral thigh-vastus lateralis flap offers reliable, stable tissue with low morbidity and good long-term outcomes. Complications compared favorably with current literature describing perineal reconstructions with rectus abdominis flaps. The composite anterolateral thigh flap is a valid alternative without the setback of abdominal donor site morbidity.

Quality of life and sexual health after perineal reconstruction in Fournier gangrene using pedicled anterolateral thigh flaps

Objectives

To assess long-term sexual outcome and quality of life after perineal reconstruction by pedicled anterolateral thigh (ALT) flaps after Fournier's gangrene. Postoperative surgical outcomes were assessed; quality of life and sexual function were assessed at long term follow-up (>12 months) with 2 scientifically validated questionnaires.

Methods

We conducted a retrospective analysis of a prospectively maintained database. Long-term sexual function and quality of life were assessed by standardized questionnaires. Descriptive statistics were conducted.

Results

8 patients were included in our study, 5 patients responded to quality of life and sexual function analysis. Surgical outcomes were in line with literature: one minor complication (minor dehiscence requiring a skin graft), one major complication (flap loss, requiring a second, contralateral flap) occurred. No reconstructive failure occurred. Average time to complete wound healing was 17 days (SD ±5). Quality of life scores over 70/100 in four out of five categories; social function was rated lowest: patients reported very few residual complaints. Sexual outcome analysis emphasizes the positive impact of the reconstruction. As expected, Fournier's Gangrene heavily affected patient's sexual health.

Conclusions

Perineal reconstruction with ALT shows excellent quality of life, and good sexual health outcomes. Currently the lack of reliable and relatable data leads to the impossibility to compare different reconstructive procedures. We emphasize that assessing sexual function and quality of life after perineal reconstruction is paramount to weigh reconstructive success.

Acute limb ischemia following perineal reconstruction in lithotomy position: take-home message for plastic surgeons

Despite the extensive use of lithotomy position in several plastic surgery procedures, most reports regarding the related incidence of complications are presented in the urologic, gynecologic, and anesthesiologic fields. We present the case of a 54-year-old male patient. polytrauma patient who underwent internal iliac artery embolization leading to extensive gluteal necrosis requiring: debridement, abdominoperineal resection and composite anterolateral thigh flap reconstruction with prolonged lithotomy position. The patient presented lower limb ischemia briefly after surgical theater. A computed tomography scan revealed the obstruction of the left superficial femoral artery requiring emergency revascularization. Arterial thrombosis is a potentially devastating complication and plastic surgeons should be aware of the possible dangers when performing surgeries in prolonged lithotomy position. Preoperative detection of patients at high risks for developing complications should be performed in order to implement preventive measures and avoid potentially life-threatening sequelae.

Individually Tailored Approach to Reconstruction of Complex Defects Using Versatility of the Lateral Circumflex Femoral Artery System-Based Pedicled Flaps

Lateral circumflex femoral artery (LCFA) system is one of the most versatile donor sites in the body. We present our experience with pedicled flaps from the LCFA system, including different components for a wide variety of etiologies and locations. Twenty-three consecutive pedicled flaps were performed on 22 patients (10 females and 12 males; age 4-71 years) between 2007 and 2015 by a single surgeon. Flap size, type, and composition were tailored according to the requirements of the defects, including (1) location; (2) surface area; (3) depth; (4) number of defects; (5) presence of exposed critical structures; (6) presence of exposed foreign bodies; (7) prior use of other options; (8) history of radiation; and (9) other comorbidities. Defect locations were 10 abdominal wall (including groin and pubis), 9 ischio-gluteo-trochanteric and 4 perineal. Defect sizes ranged from 6 × 6 to 30 × 35 cm. Maximum depth of wounds ranged between 7 and 18 cm. The flap sizes ranged from 9 × 6 to 38 × 20 cm. Two flaps were fasciocutaneous perforator, 4 were myocutaneous with "muscle sparing" vastus lateralis, 10 were myocutaneous with "segmental" vastus lateralis, 5 were myocutaneous "tri-muscle," 1 was "tri-muscle," and 1 was rectus femoris only. Donor sites were closed primarily in 20 cases and with split thickness skin grafting in 3 cases. All flaps survived completely without any partial loss or congestion. Pedicled flaps from the LCFA system can be tailored individually for a wide variety of etiologies and locations. Muscles can be harvested and used as "muscle sparing," "segmental," and "tri-muscle" to accommodate the requirements of the defects.

Abdominal, perineal, and genital soft tissue reconstruction with pedicled anterolateral thigh perforator flaps

Background

Pedicled perforator flaps have become a contemporary alternative to muscle flaps for soft tissue reconstruction as they have reduced donor site morbidity, avoid the need for microsurgical transfer, and are versatile and reliable. The anterolateral thigh (ALT) flap was first introduced as a free flap and has since gained popularity as a pedicled flap. Here we review our experience using pedicled ALT flaps for regional soft tissue reconstruction.

Methods

We retrospectively reviewed all patients who underwent loco-regional soft tissue reconstruction using pedicled ALT flaps between March 2014 and October 2018, with the goal of identifying potential applications of pedicled ALT flaps. The following aspects of each case were reviewed: patient demographics, defect location and size, comorbidities such as previous radiotherapy, flap details, clinical follow-up, and postoperative complications.

Results

Our analysis demonstrates the versatility of pedicled ALT flaps in a variety of indications to successfully cover large abdominal, perineal, and genital soft tissue defects. Depending on the patient’s needs to achieve more bulk or stability in the reconstruction, the ALT flap was individually tailored with underlying muscle or fascia. The average follow-up was 7 months (range: 3–13 months).

Conclusions

Pedicled ALT flaps are a valuable reconstructive option for soft tissue defects located within the pedicle’s range, from the lower abdomen to the perianal region. These flaps are usually raised from a non-irradiated donor site and are sufficient for covering extensive soft tissue defects. Three-dimensional reconstruction of the defect using pedicled ALT flaps allows for anatomical function and minor donor sites.

Level of evidence: Level IV, therapeutic study.

Total scrotal reconstruction following Fournier's gangrene with bilateral prelaminated superior medial thigh flaps

The patient is a 45-year-old man diagnosed with Fournier's gangrene and underwent treatment for septic shock, broad-spectrum antibiotic therapy and extensive surgical debridement of perineum, including total scrotectomy, ischiorectal fossa, abdomen and left superior thigh and flank. The patient required multiple staged complex reconstruction of the scrotum utilising prelaminated superior medial thigh flaps with use of dermal matrix, split-thickness skin grafting and pedicled gracilis muscle flap for coverage of the ischiorectal wound. The patient had full recovery and followed up 1 year postoperatively. This report discusses our technique for total scrotal reconstruction and provides review of surgical reconstructive techniques for wounds due to Fournier's gangrene.

Flap coverage for necrotising soft tissue infections: A systematic review

BACKGROUND

Necrotising soft tissue infections (NSTI) are destructive and often life-threatening infections of the skin and soft tissue, necessitating prompt recognition and aggressive medical and surgical treatment. After debridement, the aim of surgical closure and reconstruction is to minimize disability and optimize appearance. Although skin grafting may fulfil this role, techniques higher on the reconstructive ladder, including local, regional and free flaps, are sometimes undertaken. This systematic review sought to determine the circumstances when this is true, which flaps were most commonly employed, and for which anatomical areas.

METHODS

A systematic review of the literature was conducted utilising electronic databases (Medline, Embase, Cochrane Library). Full text studies of flaps used for the management of NSTI's (including Necrotising Fasciitis and Fournier Gangrene) were included. The web-based program 'Covidence' facilitated storage of references and data management. Data obtained in the search included reference details (journal, date and title), the study design, the purpose of the study, the study findings, number of patients with NSTI included, the anatomical areas of NSTI involved, the types of flaps used, and the complication rate.

RESULTS

After screening 4555 references, 501 full text manuscripts were assessed for eligibility after duplicates and irrelevant studies were excluded. 230 full text manuscripts discussed the use of 888 flap closures in the context of NSTI in 733 patients; the majority of these were case series published in the last 20 years in a large variety of journals. Reconstruction of the perineum following Fournier's gangrene accounted for the majority of the reported flaps (58.6%). Free flaps were used infrequently (8%), whereas loco-regional muscle flaps (18%) and loco-regional fasciocutaneous flaps (71%) were employed more often. The reported rate of partial or complete flap loss was 3.3%.

CONCLUSION

Complex skin and soft tissue defects from NSTIs, not amenable to skin grafting, can be more effectively and durably covered using a spectrum of flaps. This systematic review highlights the important contribution that the plastic surgeon makes as an integral member of multidisciplinary teams managing these patients.

Anterolateral Thigh Flap With Vascularized Fascia Lata Associated With Thigh Flaps: A Case Report of an All-in-One Reconstruction of the Suspensory Ligament and Penoscrotal District After Fournier Gangrene

Radical surgical debridement after Fournier gangrene (FG) can totally change anatomical balance between structures and compromise urogenital function. This is particularly true when the suspensory ligament and the lower abdominal wall are involved, leading to erection and sexual intercourse dysfunction.We present the case of a 48-year-old man, who underwent emergency debridement and split-thickness skin graft (STSG) of inferior abdominal wall, pubis, scrotal bag and penile shaft after Fournier gangrene.Five months after the emergency procedure, bilateral medial thigh flaps recreated the scrotal compartment, whereas a pedicled composite anterolateral thigh flap including fascia lata could cover the lower abdominal wall and rebuilt the penile suspensory ligament (PSL).Healing was uneventful and the patient returned to a normal sexual life with satisfactory erection and intercourse.Composite and/or chimeric anterolateral thigh fascia lata flaps have been previously used as a reliable option for complex defects, including tendon and ligaments. We describe here, the first case in the literature of a penile suspensory ligament reconstruction.

Reconstructive Surgery of Inguinal Defects: A Systematic Literature Review of Surgical Etiology and Reconstructive Technique

BACKGROUND/AIM

This study aimed to evaluate the literature regarding surgical etiology demanding inguinal reconstructive surgery, associated reconstructive techniques and outcomes.

MATERIALS AND METHODS

A systematic literature search was performed according to the PRISMA statement between 1996-2016.

RESULTS

A total of 64 articles were included, comprising 816 patients. Two main subgroups of patients were identified: Oncological resections (n=255, 31%), and vascular surgery (n=538, 66%). Oncological resection inguinal defects were treated with pedicled myocutaneous flaps (n=166, 65%), fasciocutaneous flaps (77, 31%), muscle flaps (7, 3%) and direct closure (3, 1%). Vascular surgery complications were treated with muscle flaps (n=513, 95%). Complications for the respective subgroup (oncological resections, vascular surgery) were: infection (24%, 14%), seroma (34%, 7.5%), flap dehiscence/delayed healing (20.6%, 40.8%,). The total reintervention rate was 20%.

CONCLUSION

Reconstruction of inguinal defects should be addressed on a case-by-case basis. Myocutaneous flaps were favoured after oncological resections, while muscle flaps were preferred after vascular surgery.

Reconstruction of complex soft tissue defects including tendons with anterolateral thigh flap extended to fascia lata: Long term recovery and functional outcomes

BACKGROUND

We evaluated composite anterolateral thigh (ALT) flaps including vascularized fascia lata (FL), for stable soft tissue coverage and tendons restoration at various joint levels in a one-stage procedure.

METHODS

We performed a retrospective investigation including 21 "functional" ALT flaps between November 2006 and December 2016. In all patients included, FL was shaped to anatomical reproduce a tendon structure. Functional analysis included range of motion and force assessment. Functional scores were established according to Chen classification, DASH, and LEFS score. Defects resulted from tumor excision, trauma, burn, or infection-debridement and were distributed in four main anatomical districts: knee (seven cases), ankle (six cases), forearm-elbow (four cases), and hand-wrist level (three cases).

RESULTS

Nineteen flaps were raised as free flaps, while two as distally-based propeller flaps. Average follow-up was 38 months. Major complication requiring the harvest of a second flap was seen in two patients, whereas three flaps presented superficial necrosis and was treated in an outpatient regimen. We observed 81% of total ROM recovery compared to contralateral sides with 89% recovered articular stability. Best articulation outcomes were present in elbow reconstruction, while ankle reconstructions showed less articularity. Hospital stay was significantly reduced in hand and wrist functional reconstruction when compared with reconstruction at the ankle level (P < 0.05).

CONCLUSION

The ALT flap extended to vascularized FL provides a particularly effective and resistant tissue that can be folded to reconstruct and support tendinous structures. This can restore functional and structural integrity after complex defects in a single stage procedure.

ALT flap with vascularized fascia lata for one-stage functional patellar tendon reconstruction

INTRODUCTION

Composite anterolateral thigh (ALT) flap with vascularized fascia lata can reconstitute patellar tendon integrity and knee soft tissue coverage in one stage. However, long-term evidence of outcomes is lacking. This work analyzes long-term functional results, compares subtotal and total reconstruction of patellar tendon, and assesses the respective function of the extensor apparatus.

PATIENTS AND METHODS

Outcomes of reconstruction using 10 ALT flaps in 9 patients (age range 21-87 years) were analyzed (mean follow-up 30 ± 6 months). Knee Society Scores, isometric knee extensor strength (M1-M5), and sensory recovery were evaluated, together with active range of motion and extensor lag of the reconstructed limb, compared to contralateral.

RESULTS

Ten flaps were used for tendon replacement in 9 patients. Eight (80%) free flaps and 2 (20%) propeller distally based flaps were used. Complications requiring the harvest of a second flap were seen in 2 patients. All patients could return to their daily activities without the use of walking supports. Mean active ROM was 94.4° with an extensor lag of 9.4°, without a significant difference between partial and total patellar tendon reconstruction. The mean knee and functional scores of the Knee Society were 81/100 and 77/100, respectively.

CONCLUSION

Composite ALT flap with fascia lata can satisfy the twofold needs of functional restoration and soft tissue coverage, thus ensuring stable results in total and subtotal knee extensor mechanism reconstruction. Distally based flaps should be carefully considered, as they lead to higher complication rates.

Outcome of vulvar reconstruction in patients with advanced and recurrent vulvar malignancies

Background

The use of flaps in vulvar cancer-related reconstruction has been increasing, but few studies have evaluated the outcome and quality of life of patients after this surgery. The purpose of this study was to evaluate the outcomes of vulvar reconstruction using musculocutaneous/skin flaps in patients with advanced and recurrent vulvar malignancies.

Methods

Patients with vulvar malignancies who underwent vulvar reconstruction using different types of flaps were retrospectively reviewed. Patient outcomes were evaluated with a focus on quality of life and prognosis.

Results

Thirty-six patients were enrolled, 58.33 % of them used anterolateral thigh flap (ALT), 16.67 % of them used pudendal thigh flap (PTF), 11.11 % of them used deep omferior epigastric perforator (DIEP) and gracilis myocutaneous flap were used in 2.78 % of the patients, the other 11.11 % patients used two types of flaps. Eleven patients (30.56 %) developed complications, including 5 patients (13.89 %) with partial necrosis, 5 (13.89 %) with minimal wound dehiscence and 1 (2.78 %) with flap cellulitis. All patients who developed partial necrosis (13.89 %) underwent reoperation. The mean verbal rating scale score was 1.44 before reconstruction and 0.17 after surgery (P < 0.0001). The mean performance status was 1.67 before surgery and improved to 0.31 after surgery (P < 0.0001). The median overall follow-up time after vulvar reconstruction was 9 months. Twenty-one patients (58.3 %) developed recurrence at a median interval of 5 months after vulvar reconstruction. After a median follow-up time of 14 months, 41.7 % of the patients were living and disease-free. The 5-year survival of the 36 patients was 53.8 %.

Conclusion

Soft tissue reconstruction in patients undergoing resection of advanced/recurrent vulvar malignances is associated with a low rate of postoperative complications, decreased pain, and improved functional status. Although the recurrence rate in this patient population is high, a reasonable proportion of patients who undergo resection for advanced/recurrent vulvar cancer and reconstructive surgery appear to benefit.
