Pedicled deep inferior epigastric perforator flap for lower abdominal defects and genital reconstructive surgery

The pedicled deep inferior epigastric perforator (DIEP) flap can be used successfully to reconstruct the lower abdominal, inguinal, and genital regions. This muscle-sparing technique offers many advantages, such as minimal donor-site morbidity, a wide arch of rotation, and more versatile flap design, and provides for easier reconstruction than free flaps. Four pedicled DIEP flap cases are described in this article. The flaps were used to reconstruct lower abdominal defects and groin defects and to perform a penile reconstruction. To the best of our knowledge, ours is the first report in the English literature to describe the use of a pedicled DIEP flap for penile reconstruction. The donor sites were closed directly, and morbidity in all cases was minimal.     

Thirty-year experience of utility of island groin flap for scrotal defect single-stage reconstruction

For the last 32years, we have been using island groin flap successfully to cover the scrotal defects in a single stage with good results. This flap utility for single-stage urethral fistula repair was first reported by the senior author in 1987 and was published in Br J Urol.¹We have performed single-stage repair of scrotal defects of medium and moderate size with this flap in 25 cases of Fournier's gangrene and in 4 cases of scrotal avulsion injuries due to road traffic accidents. All had good aesthetic results. More than 50% scrotal size defects were treated by a single groin flap alone. In cases with total loss of the scrotum, the groin flap was used along with two superior medial pedicle thigh flaps. Here, we have included cases of single-stage reconstruction of scrotal reconstruction by island groin flap alone. All our patients were operated under spinal anaesthesia. The results were satisfactory for the patients. We conclude from our 30 years of experience of utilizing this vascular island groin flap for a single-stage repair of scrotal defects of moderate size to be a procedure of better choice.     

Perineoscrotal reconstruction using a medial circumflex femoral artery perforator flap

Major scrotal defects may result from infection due to Fournier's gangrene, excision of scrotal skin diseases, traumatic avulsion of scrotal and penile skin, and genital burns. The wide spectrum of bacterial flora of the perineum, difficulty in providing immobilisation, and obtaining a natural contour of the testes make testicular cover very difficult. Various methods have been reported to cover the penoscrotal area, including skin grafting, transposing them to medial thigh skin, and use of local fasciocutaneous or musculocutaneous flaps. In this report, reconstruction using six local medial circumflex femoral artery perforator (MCFAP) flaps was undertaken in five male patients (mean age, 47 years) with complex penoscrotal or perineal wounds. The cause of the wounds in four patients was Fournier's gangrene, and was a wide papillomateous lesion in the other patient. Flap width was 6-10 cm and flap length was 10-18 cm. The results showed that a MCFAP flap provided the testes with a pliable local flap without being bulky and also protected the testicle without increasing the temperature. The other advantage of the MCFAP flap was that the donor-site scar could be concealed in the gluteal crease. Our results demonstrated that the MCFAP flap is an ideal local flap for covering penoscrotal defects.     

Sensory nerve repair in perforator flaps for autologous breast reconstruction: sensational or senseless?

The spontaneous return of sensation in autologously reconstructed breasts, especially in the Transverse Rectus Abdominis Myocutaneous (TRAM) flap, generated the belief that sensory reinnervation by nerve repair of the flap would be superfluous. This study compares the sensation of the following non-reconstructed and reconstructed breasts: (1) non-operated breasts; (2) flaps of patients reconstructed with the Deep Inferior Epigastric Perforator (DIEP) flap with sensory nerve repair; (3) flaps of patients reconstructed with the Deep Inferior Epigastric Perforator (DIEP) flap without nerve repair; and (4) flaps of patients reconstructed with the free TRAM flap without nerve repair. Statistically significant lower pressure thresholds were found for DIEP flaps with nerve repair through Semmes-Weinstein testing. More segments of the DIEP flaps with nerve repair reacted to cold, warm and vibratory stimuli compared to flaps without nerve repair. Delayed but satisfactory sensory evoked potential responses were obtained for all reconstructed breasts, but in 46% of TRAM flaps no response could be registered compared with 23% and 0% for DIEP flaps without and with nerve repair, respectively. Questionnaires confirmed the objective data and showed return of erogenous sensation in 30% of the patients with DIEP flaps with nerve repair. Our data reconfirm the possibility of spontaneous return of sensation in pedicled and/or free lower abdominal flaps without nerve repair. Nerve repair in free DIEP flaps nevertheless does restore sensation earlier postoperatively, increases the quality and quantity of sensation in the flap and has a higher chance of providing erogenous sensation. The benefits obtained outweigh the disadvantages of the increased operating time.     

Buttock reconstruction using a pedicled deep inferior epigastric perforator flap

Although deep inferior epigastric perforator (DIEP) flaps are mainly used for breast reconstruction as free flaps, they are also useful as pedicled island flaps. However, DIEP flaps have seldom been used for reconstructions in the lateral hip region. Furthermore, to the best of our knowledge, no report has been issued on the use of this flap for buttock reconstruction. The authors describe the successful use of a pedicled oblique DIEP flap for the reconstruction of a severe scar contracture in the buttock. The pedicled DIEP flap can be a useful option for the reconstruction of large buttock defects, and if a transverse DIEP flap is unavailable, an oblique DIEP flap should be considered an alternative.     

Versatility of the vertical designed deep inferior epigastric perforator flap

The deep inferior epigastric perforator (DIEP) flap is one of the most commonly used perforator flaps. However, when horizontally oriented, it has certain pitfalls such as sacrifice of the contralateral donor site, the need to discard soft tissue that will not be adequately perfused, and long operating times. To overcome these handicaps, the flap in a vertical orientation was designed and demonstrated the versatility of this technique in a number of different anatomical tissue restorations in this study. The vertical DIEP flaps were used in 8 patients (7 males and 1 female) in 3 years. Defects were located in the lower limb (4 cases), face (3 cases), and hip (1 cases). All flaps were transferred as free, except one in the hip that was pedicled. Flap sizes varied from 7 × 5 cm to 13 × 9 cm. All donor defects were closed primarily. The mean follow‐up time was 13.6 months. All flaps survived totally, but one which had partial necrosis. A hematoma developed postoperatively in the donor site of the pedicled DIEP flap. Cosmetic outcomes were satisfactory in all patients. All donor site scars were acceptable with minimal contour irregularities. The vertical DIEP flap offers diverse opportunities in various soft tissue reconstructions and is candidate to be an important choice of free flap repertoire. The method can be proposed particularly for restoration of moderate sized defects rather than that of large defects as in postmastectomy breast reconstruction. © 2009 Wiley‐Liss, Inc.

Use of the scrotal remnant as a tissue-expanding musculocutaneous flap for scrotal reconstruction in Paget's disease

Wide excision of extramammary Paget's disease of the penoscrotal region may leave large defects that cannot be closed easily. The authors describe their experience with a series of 6 patients in whom reconstruction of the scrotal defect was undertaken using the scrotal remnant raised as a stretchable musculocutaneous flap. It was observed that as little as a third of the residual scrotum could be expanded to resurface the entire scrotum. All flaps survived completely. Severe scrotal edema and ecchymosis were observed in 1 patient but the symptoms resolved completely with Trendelenburg positioning. The penile defects were resurfaced individually with thick skin grafts. Good-quality take with no chordee was observed in all patients after initial reconstruction. One patient developed penile contracture after reexcision of recurrent disease. Mean follow-up was 22 months (range, 3-60 months). Large defects of as much as two thirds of the scrotum may be reconstructed successfully using the tissue-expanding scrotal musculocutaneous flap.     

Buried deep inferior epigastric perforator flaps for complex head and neck contour defects

The deep inferior epigastric perforator (DIEP) flap is presented as a potential source of tissue for head and neck reconstruction. It has been sparingly reported for pharyngeal reconstruction and to provide a large bulk of skin but not previously described for buried contour defects. We present a retrospective study of a consecutive series of six buried DIEP flaps performed between 2005 and 2007 with a review of their indications, results, and complications. Three patient defects had previous radiation. All flaps were used in the delay setting as secondary reconstructions. Soft tissue defects addressed in this study were the result of a variety of different pathologies, including temporal fossa meningioma, fibrous dysplasia of the skull and orbit, nasopharyngeal carcinoma, neck scar repair, sinus cancer, and osteomyelitis. We report a 100% success rate with primary flap survival, secondary contouring, minimal donor site, provision of moldable bulk soft tissue fill, and ability to fillet and redistribute. Patient-reported satisfaction at 6 months and 1 year was good to excellent in all cases. We concluded that in select cases, the functional and aesthetic advantages of the DIEP flap for head and neck reconstruction of soft tissue defects are superior to implants, fillers, and nonvascularized fat grafts. During revisions, these flaps are amendable to liposuction as a contouring tool with portions that can be redistributed on pedicles. The subcutaneous fat of the DIEP flap has resilience that tends to last and retain its shape with maintenance of residual volume over muscle flaps.     

Head and neck reconstruction with the deep inferior epigastric perforator flap: A report of two cases

Rectus abdominis musculocutaneous (RAMC) free flaps are preferred for head and neck reconstruction because of the abundant blood supply to the rectus abdominis musculocutaneous. In contrast, the indications for deep inferior epigastric perforator (DIEP) free flaps in head and neck reconstruction are limited. In this report, two cases of oral cavity reconstruction with DIEP free flaps are described. In both cases, the defect was reconstructed with a DIEP free flap because it could avoid functional damage to the donor site. Successful reconstruction with a two skin‐island method was performed in both patients. Furthermore, donor site morbidity was minimal in both patients. When a DIEP free flap is used for head and neck reconstruction, elimination of dead space is the most difficult problem, because a DIEP free flap does not contain well‐vascularized muscle tissue. We compensate for this disadvantage with a flap designed to include a de‐epithelialized skin flap. Although this technique is not always the first choice for head and neck reconstruction, it is suitable for patients who wish to avoid donor site morbidity. © 2009 Wiley‐Liss, Inc.

Breast reconstruction with superior epigastric artery perforator (SEAP) free flap: Report of two cases

The deep inferior epigastric artery perforator (DIEP) flap is the gold standard for autologous breast reconstruction. When the DIEP pedicle is damaged, alternative perforator flaps are harvested from sites with less donor tissue, such as the thigh. Pedicled superior epigastric artery perforator (SEAP) flaps have been recently described for reconstruction of inferior partial breast defects. The purpose of this report is to show the surgical technique of the free SEAP flap for reconstruction of the entire breast in two patients. The authors describe two patients where the DIEP pedicle was unavailable. The first patient was 53 years old, with body mass index (BMI) 22.7, while the second patient was 60 with BMI 32.4. The donor site was marked as for a DIEP, and two lateral row perforators were selected in each case. Flaps were designed to cross the midline, with adequate perfusion confirmed via indocyanine green angiography. Both flaps were rotated 90° counterclockwise for inset into the chest. Flap size and weight for the two patients were: 24 × 15 cm and 350 g; and 25 × 15 cm and 400 g. Both patients had a routine postoperative course without complications. Length of follow-up was 155 and 158 days, respectively. We believe that the free SEAP flap is a promising technique in select patients who require an alternative to the DIEP for autologous breast reconstruction.     

Breast Reconstruction with Microvascular MS-TRAM and DIEP Flaps

The free muscle-sparing transverse rectus abdominis myocutaneous (MS-TRAM) and deep inferior epigastric perforator (DIEP) flaps involve transferring skin and subcutaneous tissue from the lower abdominal area and have many features that make them well suited for breast reconstruction. The robust blood supply of the free flap reduces the risk of fat necrosis and also enables aggressive shaping of the flap for breast reconstruction to optimize the aesthetic outcome. In addition, the free MS-TRAM flap and DIEP flap require minimal donor-site sacrifice in most cases. With proper patient selection and safe surgical technique, the free MS-TRAM flap and DIEP flap can transfer the lower abdominal skin and subcutaneous tissue to provide an aesthetically pleasing breast reconstruction with minimal donor-site morbidity.     

Bilateral super thin groin island flap for penile, scrotal, and pubic reconstruction after Fournier��s gangrene

Defects in the scrotal, perianal, and penile areas are problems that are difficult to repair. Methods for reconstruction of this region are limited, and none are ideal. We decided to use bilateral super thin groin island flaps for a patient with penile, scrotal, and pubic defects. A two-stage technique for scrotal sac and penile reconstruction using tissue expansion is described. A super thin groin island flap was elevated, and bilateral tissue expanders were placed. Using this, the penile, scrotal, and pubic defects were closed without difficulty. Both the aesthetic and functional aspects should be taken into consideration when covering a defect of both the testis and the penis. It is essential to have thin and durable cover for such a reconstruction. The technique described above was used to reconstruct this defect with good functional and cosmetic outcomes.     

Single-stage repair of urethral fistula by vascular island groin flap

A new technique for the repair of a urethral fistula at the penoscrotal junction is presented. Under local anaesthesia we have successfully repaired six of these fistulae using a groin island pedicle flap. The urethra is repaired by mobilising the mucous lining around the fistula and closing it longitudinally, using absorbable 4/0 chromic catgut sutures. The groin island pedicle flap which is based on superficial circumflex iliac vessels is used to cover the repaired lining. The donor defect is closed primarily. In all six cases there was primary healing. This procedure is recommended for cases where the skin around the fistula is badly scarred or where previous attempts at closure have failed. Moderate defects of penile and scrotal skin can also be repaired by this type of flap.     

Application of a lateral groin flap in reconstructive and reparative surgery of the perineal region

Since March 1983, the authors have applied three types of lateral groin flap to reconstruct the external genitals and to repair skin defects in the perineal region in 16 cases. (1) A single lateral groin flap was used to construct vagina in two patients; (2) A composite flap containing iliac crest bone was applied to reconstruct penis in 11 cases; (3) A coaxial pedicle flap of the lateral groin and lower abdominal area was used to repair skin defects of the penis and scrotum in two cases, and to relieve postburn scar contracture in the perineal region in another. 14 flaps survive completely with satisfactory results. 70 per cent of 1 composite flap was lost because of hematoma. The distal portion (3 x 5 cm) of 1 single flap necrosed due to injury of the deep branch of SCIA during operation and resurfaced with a free skin graft, final result is fair.     

Utility of the free deep inferior epigastric perforator flap in chest wall reconstruction

Breast cancer chest wall recurrence is often treated with chemotherapy, radical surgery, and radiation. Extensive chest wall resection requires soft-tissue reconstruction with tissue that provides chest wall stability and durability for additional radiation. Local and regional muscle and musculocutaneous flaps are often used for reconstruction. Free flaps, such as the transverse rectus abdominis musculocutaneous flap, are used for large defects, although donor site morbidity can result. The free deep inferior epigastric perforator (DIEP) flap provides coverage for large defects and may have less donor site morbidity. We describe the use of the free DIEP flap to reconstruct large chest wall defects (mean, 501 cm2 defects) after the resection of recurrent breast cancer in two patients. One patient had 2% flap loss. No donor site morbidity occurred. The free DIEP flap is a durable and reliable flap that provided immediate and complete coverage of these large chest wall defects with no donor site morbidity and did not delay the administration of adjuvant therapy.     

A reappraisal of the free groin flap in aesthetic craniofacial reconstruction

Craniofacial defects are often associated with 3-dimensional volumetric contour deficiencies. The free groin flap was historically popular though technical limitations subsequently caused its use to fall from favor. We sought to determine if a role remained for the free groin flap in aesthetic craniofacial reconstruction. From May 2005 to July 2010, 15 patients had 18 consecutive free groin flaps performed by the senior surgeon at the R Adams Cowley Shock Trauma Center and the Johns Hopkins Medical Institute. Data collected included age, sex, operative date, etiology, defect size, recipient vessels, complications, donor-site closure, and follow-up time. Eighteen groin flaps were used for the patient cohort consisting of 10 males and 5 females (mean age, 26 years; range, 18-40 years) who underwent reconstruction necessitated by various oncologic, traumatic, infectious, and congenital etiologies. The average defect size was 7.3 × 6.3 cm (range, 3-10 × 1-10 cm). Seventeen flaps were based on the superficial circumflex iliac vessels and 1 on the superficial inferior epigastric vessels. Seventeen flaps used the superficial temporal artery and vein as the recipient vessels, and the remaining flap used the superior thyroid artery and retromandibular vein. Of the 18 flaps, 17 survived (94% survival rate). All donor sites were closed primarily. Follow-up time ranged from 6 to 60 months. The free groin flap is generally underused in the reconstruction of complex craniofacial facial defects. Its unique characteristics and minimal donor-site morbidity should prompt the reconstructive surgeon to retain the free groin flap in his or her armamentarium.     

The dissection of the rectus abdominis myocutaneous flap with complete preservation of the anterior rectus sheath.

Harvesting the rectus abdominis myocutaneous flap results in defects in both the rectus abdominis muscle and the anterior rectus sheath, which may be circumvented by dissecting a perforator flap (DIEP flap) instead. However, the latter is associated with a reduction in the number of myocutaneous perforators nourishing the flap, which has been hypothesised to lead to an increased risk of partial flap failure. We present a technical modification that maintains all the feeding perforators within the flap while fully preserving the anterior rectus sheath. The anterior rectus sheath is incised along a line connecting the perforators. A muscle cuff including all the feeding perforators was raised with the flap. This technique was used in 20 consecutive patients. Nine patients underwent free TRAM flap transfers for breast reconstruction (10 flaps), and 11 patients underwent thoracic-wall reconstruction with a superiorly based pedicled flap. The median follow-up was 11 months. One patient with a pedicled flap developed a partial failure that required surgical revision; all other flaps healed spontaneously. One patient in each subset had preoperative abdominal-wall laxity that was partly corrected after surgery; no abdominal bulging or hernia occurred in the other patients. Our results suggest that the technical modification presented here may enable the surgeon to dissect a rectus abdominis myocutaneous flap with maximal perforator-related flap perfusion and minimal donor-site morbidity. An advantage over the DIEP flap is that this technique is applicable to both free and pedicled flaps.     

Reconstruction of the external genitals and repair of skin defects of the perineal region using three types of lateral groin flap

Three types of lateral groin flap have been applied to reconstruct the external genitals and to repair skin defects in the perineal region. A single lateral groin flap was used to construct a vagina for 2 patients who had congenital absence of vagina. A composite flap containing iliac crest bone was applied to reconstruct the penis in 11 patients: 8 suffered traumatic amputation and 3 had congenital micropenis. A coaxial pedicle flap of the lateral groin and abdominal area was used to repair skin defects of the penis and scrotum after resection of the elephantiasis caused by recurrent erysipelas in 2 patients, and to relieve postburn scar contracture in the perineal region in another. Using this operative technique, 14 flaps survived completely with satisfactory results; 70% of one composite flap was lost as a result of hematoma. In the single-flap group, the distal portion (3 x 5 cm) of one flap necrosed and was resected and resurfaced with a free skin graft; the final result was good.     

Adipofascial anterolateral thigh free flap for tongue repair.

With the advent of microsurgery fasciocutaneous free flaps have become a well known and accepted option for the repair of tongue defects. Many authors have tried to recover tongue function by modifying this approach. An innovative method for the repair of tongue defects using an adipofascial anterolateral thigh free flap is presented in this paper. The results are compared with those of tongue reconstructions implementing traditional fasciocutaneous free flaps performed at our institution. The histological features of the flaps were investigated postoperatively. Although this preliminary report has to be confirmed by further experience, it seems to solve many tongue-reconstruction related problems.     

Treatment of radiation necrosis of skin, muscle and bone in oncology

Following the wide excision of radiation necrosis, the treatment of these lesions has been transformed by the use of the myocutaneous flap technique. The most widely used, flaps are latissimus dorsi flaps for chest wall, subclavicular defects, pectoralis major flaps for defects of the neck and lower part of the face, fascia lata flaps to treat lesions of the groin and lower abdominal wall, gracilis flaps for perineal defects, gluteus maximus flaps for the ischial and sacral region. Due to their good blood supply and their thickness, they can be used to repair large defects and they ensure very good protection against infection. Omentum can be useful when a myocutaneous flap cannot be performed or in association with this flap. Good cosmetic results can be obtained with free myocutaneous flaps for lesions located on the head or on the limbs. Such flaps require micro vascular anastomoses.
