Reconstructive Techniques

Abdominal wall defects resulting from recurrent hernias, trauma, and radiation necrosis are difficult and challenging to repair given the high rates of recurrence and surgical morbidity. Complex abdominal wall defects often require the transposition of autologous material to bridge the fascial gap. We present a review of niche reconstructive techniques that have been used in complex abdominal wall repair. The specific techniques reviewed include use of delayed and tunneled pedicled tensor fascia lata myofascial flap, de-epithelialized flap closure, free latissimus dorsi myocutaneous flap with or without innervation, and abdominal wall transplant. These niche surgical techniques have great potential to reduce recurrence rates when used in the proper setting for complex abdominal wall reconstruction. More studies are needed to evaluate the relative use of these techniques with the more widely established surgical methods of reconstruction.

Background and aims. In the age of synthetic prostheses most of hernia studies include a careful examination of the various types of prosthesis, their characteristics and their repair indications. Biological prostheses are also beginning to draw attention. But in terms of recurrence especially for poor or developing countries, the discussion is different, due to their high cost which makes them difficult to afford. In this article we present new flap reconstruction techniques for the reconstruction of the abdominal wall versus mesh repair, applied on swine models, outline the results of each technique, and specify the indications for their use.Methods. An experimental protocol using four swine models (PIC-FII-337 hybrid breed pigs), five months old, was conducted. All animal care and operative procedures were studied following the protocol approved by the Ethics Committee of the University of Medicine and Pharmacy resolution no. 281/2014 of the Department of Surgery of the University of Agricultural Sciences and Veterinary Medicine); the study was carried out between November 2015 and February 2016. The primary objective was to compare the effect of surgical strategies in the treatment of the abdominal wall defect using variable flaps versus mesh repair in a large-animal models. Physical examination and ultrasound imaging of the abdominal wall repair were done on determined periods, during one month. The complications occurring after the abdominal wall repair were edema, collections, superficial dehiscence an recurrences.Results. No recurrences were reported at one month results, all seromas reported were solved over time by natural drainage. Superficial necrosis appeared in two swine models and superficial dehiscence occurred in one model, the perforator ”plus” flap. Mesh infection was detected in the “onlay” swine model.Conclusions. In terms of recurrences, contaminated abdominal wall defects or other contraindications to the use of prosthetic materials, biological mesh repair or flap surgery are the only surgical options. Based on our findings and considering the high cost reported by the biological meshes use, flap surgery becomes the suitable treatment for such cases, allowing a good reconstruction of the abdominal wall.

Abstract Aim The use of synthetic mesh to repair infected defects of the abdominal wall remains controversial. PVDF mesh was introduced in 2002 as an alternative to polypropylene, with the advantages of improved biostability, lowered bending stiffness, and minimum tissue response. This study aimed to evaluate the short-term outcomes of using PVDF mesh to treat infected abdominal wall defects in the elective setting. Material and Methods A prospective clinical trial started in 2016 and designed to evaluate the short and mid-term outcomes of 38 patients submitted to abdominal wall reconstruction in the setting of active mesh infection and/or enteric fistulas (AI) when compared to a group of 38 patients submitted to clean ventral hernia repairs (CC). Patients were submitted to single-staged repairs, using onlay PVDF mesh reinforcement to treat their defects. Results Groups had comparable demographic characteristics. The AI group had more previous abdominal operations and a longer operative and anesthesia time. At 30-days, surgical site occurrences were observed in 18 (47.4%) AI vs. 17 (44.7%) CC; surgical site infection occurred in 4 (10.4%) AI vs. 6 (15.8%) CC, and a higher number of procedural interventions were required in the CC group, 15.8% AI vs. 28.9% CC. At 6-months follow-up, no chronic infections or hernia recurrences were observed in both groups. Conclusions The use of PVDF mesh in the infected setting presented very favorable results with a low incidence of wound infection.

The closure of the abdominal wall defects is a fascinating field within surgery. The combined strength of sutures and scar after simple approximation of tissues in many cases does not suffice to contain the abdominal viscera and an incisional hernia results. Surgical failure can be seen immediately in the dramatic form of a dehiscence or can emerge slowly over time with a change in the abdominal shape and contour. This chapter delves into the theory and practicum of how a surgeon can approximate two halves of an abdominal wall together to resist the inherent tensile forces that exist and create a durable closure.

Background Reconstruction of large abdominal wall defects provides unique challenges to the plastic surgeon. Reconstruction with innervated free flaps has been described and allows for true functional replacement of “like with like.” The authors sought to determine the frequency and outcomes of such reconstructions. Methods A literature review was performed using MEDLINE (PubMed), EMBASE, and the Cochrane Collaboration Library for research articles related to innervated free flaps in abdominal wall reconstruction. Results Nine case series (16 patients) were included who underwent free flap reconstruction of the abdominal wall with motor and/or sensory innervation. Reconstruction was performed with latissimus dorsi (n = 5), tensor fascia lata (n = 4), rectus femoris (n = 2), combined tensor fascia lata-anterolateral thigh (n = 2), combined vastus lateralis-tensor fascia lata-anterolateral thigh flaps (n = 2), and vastus lateralis-anterolateral thigh (n = 1). All but one reconstruction had motor neurotization performed (n = 15), while only 12.5% (n = 2) had sensory neurotization performed. At least 66.6% of patients (n = 10) who had motor neurotization regained motor function as evidenced by documented clinical examination findings while 93.3% (n = 14) had “satisfactory” motor function on author's subjective description of the function. Both flaps that had sensory innervation were successful with Semmes–Weinstein testing of 3.61. Conclusion A majority of neurotized free flap reconstructions for abdominal wall defects have been performed for motor innervation, which is almost invariably successful. Sensory neurotization has been carried out for a small number of these reconstructions, and also has been successful. Improvements in techniques and outcomes in innervated free flap abdominal wall reconstruction are important to advancing efforts in abdominal wall transplantation.

ABSTRACT Background: The use of polypropylene meshes for surgical repair of the abdominal wall contributes to a reduction of the of recurrence rates of hernias or defects. However, its intra-abdominal use comes along with the formation of adhesions and several complications. The study and the search for alternative materials, including bovine pericardium, have been regarded as an option for the correction and treatment of resulting hernias with better adaptations and effectiveness. Aim: Evaluating the inflammatory process of the bovine pericardium in comparison with the inflammatory process of synthetic polypropylene mesh. Method: Bovine pericardium mesh and polypropylene mesh were placed, both on the same animal. The first group had the mesh removed for analysis on day 20, and the second group on day 40. The variables congestion, granulation, giant cells, necrosis, acute inflammation, chronic inflammation and collagen were analyzed. Results: All variables were found in greater numbers as a response to the polypropylene mesh, except for the collagen, which, on day 40, was greater in response to the bovine pericardium mesh. Conclusion: The data in this study suggest that there is less inflammatory reaction in response to bovine pericardium mesh when compared to polypropylene mesh.

Abstract Introduction The pedicled anterolateral thigh (ALT) flap is considered as a suitable option in complex abdominal wall reconstruction. Its use as a reconstructive option is infrequent in the literature, and to date, there has been no systematic review evaluating its long-term outcomes. We report our experience with the pedicled anterolateral thigh flap for abdominal wall reconstruction in high-risk patients. Method A prospective database was created for patients with abdominal wall defects treated with pedicled ALT with extended fascia lata flaps between 2014 and 2017. Patient demographics, aetiology, size, location of defect and post-operative results were reviewed. Abdominal defects were classified into the following zones: 1A, upper midline; 1B, lower midline; 2, upper quadrant; 3, lower quadrant. A systematic review of the literature was conducted using PUBMED and EMBASE. Results 4 patients (mean age 59.5 years, range 50-65 years) underwent reconstruction with pedicled ALT flaps. 3 flaps developed partial necrosis secondary to infection; 1 flap required surgical debridement, and 2 were managed conservatively. There was one flap failure, due to avulsion of the pedicle during inset. At mean follow up of 2.75 years (range 1 to 4 years) 3 patients have clinical bulging or herniation. Conclusions Review of the literature demonstrated 52 patients from 17 case series or reports. The overall infection and partial flap loss rates were both 6%. There were no reported flap failures. Our study demonstrates that the pedicled anterolateral thigh flap is an effective flap option for the repair of large defects of the abdominal wall in high-risk patients.

Abstract Aims Incisional hernias are a common complication after surgery that cause significant patient morbidity. Symptomatic patients are offered repair but many surgical techniques exist, with abdominal wall reconstruction becoming preferable for large complex defects. This paper describes our experience of abdominal wall reconstruction using a dual mesh technique. Method 22 patients underwent incisional hernia repair between March 2019 and September 2020. All patients received dual mesh, placed in retrorectus or transversalis fascial/retromuscular space. Absorbable BIO-A GORE mesh was used with a polypropylene mesh above. All patients were followed up to assess for complications and recurrence. Results No patients experienced fistula formation, long-term pain or obstructive symptoms. We report one true hernia recurrence (4.5%) and one case of infected mesh (4.5%), these both await further treatment. One patient had a proven wound infection which resolved with conservative treatment. 4 patients (18.2%) experienced seromas, 3 of these resolved spontaneously, one requiring image-guided drainage. Conclusion Incisional hernia repair using combination polypropylene and bio-absorbable mesh provides a safe and effective repair with low recurrence and incidence of surgical site occurrences in the short term. Longer follow up and further studies are needed to evaluate this mesh technique to support ongoing use of absorbable meshes in complex hernia repair.

Temporary Abdominal Closure

AbstractReconstruction of abdominal wall defects is still a big challenge in surgery, especially where there is insufficient fascia muscular or excessive tension of the defects in emergency and life-threatening scenarios. Indeed, the concept of damage control surgery has been advanced in the management of both traumatic and nontraumatic surgical settings. The strategy requires abridged surgery and quick back to intensive care units (ICU) for aggressive resuscitation. In the damage control laparotomy, patients are left with open abdomen or provisional closure of the abdomen with a planned return to the operating room for definitive surgery. So far, various techniques have been utilized to achieve early temporary abdominal closure, but there is no clear consensus on the ideal method or material for abdominal wall reconstruction. We recently successfully created the selective germline genome-edited pig (SGGEP) and here we aimed to explore the feasibility of in vivo reconstruction of the abdominal wall in a rabbit model with SGGEP meninges grafts (SGGEP-MGs). Our result showed that the SGGEP-MGs could restore the integrity of the defect very well. After 7 weeks of engraftment, there was no sign of herniation observed, the grafts were re-vascularized, and the defects were well repaired. Histologically, the boundary between the graft and the host was very well integrated and there was no strong inflammatory response. Therefore, this kind of closure could help restore the fluid and electrolyte balance and to dampen systemic inflammatory response in damge control surgery while ADM graft failed to establish re-vascularization as the same as the SGGEP-MG. It is concluded that the meninges of SGGEP could serve as a high-quality alternative for restoring the integrity of the abdominal wall, especially for damage control surgery.

Background: The association of prosthetic meshes in the abdominal wall repair , reducing the recurrence rates in an impactful way, has become an almost mandatory routine for the success of these surgeries. After decades using non-biological synthetic implants, from the 90s onwards biological acellular membranes of animal or human origin were introduced , beginning a new era in abdominal wall defects correction . Methods: Thirty patients underwent repair for different abdominal wall deformities, with acellular matrices of bovine pericardium, in a total of 40 anatomically individualized implants. The median follow-up was 22 months, with patients evaluated clinically and radiologically. In three cases, biopsies of the implanted areas were performed, allowing histological analysis of the material. Results: There was no recurrence of hernias in any of the cases, both clinically and radiologically. There was also no record of hematomas, infections or any phenomenon of a local or systemic reaction nature. Radiologically, it was not possible to visualize the matrices at the implantation site in any of the analysed postoperative periods. Biopsies showed important tissue neoformation replacing the implanted membranes, with important deposition of collagen, normal-looking cellularized tissue, and absence of foreign body reactions. Conclusions: The analysed matrices showed similarity to other biological membranes described in the international literature. Representing an important update and conceptual evolution, biological matrices must be incorporated into the therapeutic arsenal in abdominal wall repairs.
