Use of Figueiredo’s technique for treating extensive infected skin lesions – a case report

Demonstrate that a low-complexity surgical technique can effectively solve problems of extensive skin lesions in cities where microsurgical techniques are not available. We present a 59-year-old male patient with diabetes mellitus and an extensive and infected lesion in his right ankle region, suggestive of a diabetic foot. Urgent surgical treatment was performed with debridement of the devitalized tissues, drainage of a large amount of purulent secretion, and exhaustive washing with 0.9% saline solution. After a new debridement, abundant washing with 0.9% saline solution and coverage of the extensive bloody area with a polypropylene prosthesis were performed. He remained under outpatient follow-up, and subsequently, twice, new cleanings were performed, and a small diameter mesh was applied due to the good evolution of healing. A good range of motion was maintained in the right ankle and foot, with the medial wound completely healed, leaving only a small area of the lateral wound to complete the healing process. Figueiredo’s technique, described in 2017 for fingertip lesions, uses a flexible thermoplastic polymer, which can be obtained from a small portion of silicone from a saline bag, to form a semi-occlusive dressing that allows the drainage of secretions and provides a favorable environment and temperature for healing. The exact limits of this technique are not yet well established, but the practice has shown excellent results in larger lesions. Figueiredo’s technique is a simple, low-cost, and effective option for treating extensive infected skin lesions. Level of Evidence IV; Therapeutic studies; Case Report.

Laparoscopic Treatment of Bladder Prosthesis Exposure

Genital prolapse surgery is a functional surgery aimed at restoring the anatomical position and functions of the pelvic organs. Currently, the gold standard is laparoscopic surgery with a polypropylene prosthesis. This is functional surgery involving the interposition of strips and their fixation to the spine. This technique avoids the need for a vaginal opening and is therefore less prone to infectious complications and prosthesis exposure. Exposure of the prosthesis several years after insertion calls for monitoring. We present the case of a patient operated on at our level for genital prolapse using the laparoscopic lateral suspension technique, with exposure of the sling three years after insertion. We describe the various lesions found and the therapeutic strategy.

INFLUENCE OF EXPLANTATION ON THE HEMOCIRCULATION OF THE TESTICLE IN MEN OF FERTILITY AGE: LONG-TERM RESULTS, PRELIMINARY FINDINGS

Abstract. The introduction of explantation techniques into clinical practice allowed to reduce the percentage of recurrence of inguinal hernias to the level of less than 1%. But there are data indicating a negative effect on the reproductive function of men. On the other hand, a number of researchers deny the negative consequences of explantation.
 The purpose of this study is to evaluate the effect of a polypropylene prosthesis on testicular hemocirculation in men of childbearing age.
 Materials and methods. The peak systolic velocity, end-diastolic velocity and resistive index (RI) in the testicular, capsular, and intratesticular arteries were studied using the Doppler ultrasound method in 30 men aged 20-45 who underwent surgical intervention — herniotomy, Lichtenstein hernioplasty for a unilateral inguinal hernia. The obtained results were compared according to the data of the contralateral side. The study was conducted 6 and 12 months after surgery.
 Results and discussion. None of the applied parameters of testicular hemocirculation in the arteries that were studied during the observation period was statistically significantly different from the control.
 Conclusions. Within 6-12 months after hernioplasty, the synthetic explant does not have a negative effect on the state of testicular hemodynamics.

A modified Rives–Stoppa technique with composite mesh (FLaPp) in large incisional hernia: a multicentric retrospective cohort study

Summary Background Large incisional hernias (LIH) are challenging conditions, often necessitating complex surgical procedures such as transversus abdominis muscle release (TAR). We evaluated the feasibility and effectiveness of tension-free abdominal wall repair of LIH with an innovative modified Rives–Stoppa procedure employing a composite free lateral polypropylene (FLaPp) prosthesis. Methods Symptomatic patients affected by LIH and treated with FLaPp composite prosthesis between April 2010 and December 2016 were retrospectively analyzed. The FLaPp prosthesis is made up of two layers: an internal layer based on a polypropylene film that can be used in contact with the intestinal loops to address the posterior peritoneal defect, and an external layer based on a macroporous lightweight mesh, with which a classic repair according to Rives–Stoppa is carried out. Results Forty-three patients were enrolled in the study. All hernias were W3. Early complications were seroma (16.3%), hematoma (11.6%), wound infection (7.0%), and bowel injury (2.3%). Late complications were sinus tract (4.7%), occasional pain (2.3%), and stiff abdomen (9.3%). The median operative time was 126 min and median hospitalization was 8 days. At the median follow-up of 40 months (range 37.5–117), the recurrence rate was 9.3% (4/43). Conclusion Use of FLaPp mesh with a tension-free surgical approach is an effective strategy for managing LIH in selected cases with the presence of a posterior defect, with low rates of complications and recurrences.

Features of the integration of two-layer metal knitwear made of titanium nickelide during the replacement of a thoracoabdominal defect in the experiment

The aim of investigation was to study experimentally the morphological features of tissue integration of two-layer titanium nickelide (TiNi) knitwear when replacing thoracoabdominal defects.Materials and methods. The experiments were carried out on 40 Wistar rats. The experimental animals were divided into two comparison groups: in Group A (n = 20) the defect was replaced using a two-layer knitted tape made of TiNi, in Group B (n = 20) a polypropylene mesh implant was used. The technique of the operation and the peculiarities of keeping the animals did not differ. Animals were taken out after 14, 30, 60 and 90 days of experiment. The macroscopic structural features at the site of implant fixation to tissues and at the sites of contact with underlying organs were studied, and the inflammatory process was assessed. The histological and electron microscopic study was carried out with an assessment of the features of tissue integration through the mesh structure of knitwear.Results. Thirty days after the surgery in four cases of Group B the appearance of the chest wall deformation at the site of implant fixation was noted, in one case the deformation site was located along the lateral edge of the abdominal wall. Among the animals of Group A no such changes were recorded. The histological and electron microscopy examination revealed that the porous structure of the TiNi wire, as well as the biomechanical and biochemical properties of the two-layer metal knitwear, ensure optimal integration of the endoprosthesis in the body tissues, forming an elastic frame close to natural. In Group B, on the contrary, the reaction of the body caused by the implanted polypropylene prosthesis was characterized by more pronounced fibrosis, and tissue integration through the mesh structure of the implant was not observed.Conclusion. Two-layer TiNi knitwear in the replacement of complex structures of the thoracoabdominal zone showed promising results, which opens up prospects for further clinical research.

ONLAY VERSUS RIVES-STOPPA TECHNIQUES IN THE TREATMENT OF INCISIONAL HERNIAS.

In the surgical correction of large incisional hernias, the use of a prosthesis is essential in most cases regardless of the technique chosen. The preference is for the polypropylene prosthesis. To compare the onlay and Rives-Stoppa techniques in the correction of incisional hernias, their immediate results, complications, advantages, and disadvantages. Two groups of patients with incisional hernias were analyzed, submitted to the onlay (19 patients) and Rives-Stoppa (17 patients) techniques, and that used polypropylene prostheses. General epidemiological variables, perioperative data variables, and postoperative complications were assessed. The patients' epidemiologic profile was similar between both groups. The majority were women (58.4%), with a mean age of 65.5 years and a previous mean body mass index of 41.5 kg/m². The Rives-Stoppa technique was employed in most patients (52.7%). Those submitted to the onlay technique had longer abdominal drainage time and longer hospital stay, as well as a higher incidence of seromas and surgical wound infection. The incisional herniorrhaphy technique with the placement of a pre-peritoneal polypropylene mesh by the Rives-Stoppa technique was superior to the onlay due to lower rates of drain use, hospital stay, and postoperative complications.

Treatment of Extensive Soft Tissue Injury with Polypropylene Prosthesis: A Case Study.

Injuries with exposure of soft tissue are frequent in orthopaedics. Innovative therapies using prosthesis as an auxiliary material to treat this type of injury are under development, aiming to overcome applicability and execution limitations of myocutaneous flap techniques. Figueiredo's technique uses a polypropylene prosthesis extracted from sterile saline to treat trauma at the fingertip. It is an alternative technique with a high success rate, reproducible, low cost and easy to apply. This article reports a case of foot injury with exposure of soft tissue treated with a treatment similar to Figueiredo's technique. The patient was admitted with a large and contaminated skin wound, muscle damage, tendon exposure, cuboid fracture and bone loss. Initially, debridement was performed. After 72 hours, a polypropylene prosthesis extracted from a sterile saline bottle was implanted and subsequently replaced after 60 days. After 76 days, the prosthesis was removed. There was no infection. 8 months later, there was total healing by second intention. The patient's motor and sensory functions were preserved. This case study shows that Figueiredo's technique can also be employed in more extensive injuries, representing an alternative to using myocutaneous flaps. The polypropylene prosthesis is extremely affordable, which enables resolution of cases in a greater number of services. This technique still offers the best aesthetic result and does not compromise other body regions.

Dual-Responsive Polypropylene Meshes Actuating as Thermal and SERS Sensors.

Polypropylene (PP) surgical meshes, with different knitted architectures, were chemically functionalized with gold nanoparticles (AuNPs) and 4-mercaptothiazole (4-MB) to transform their fibers into a surface enhanced Raman scattering (SERS) detectable plastic material. The application of a thin layer of poly[N-isopropylacrylamide-co-N,N'-methylene bis(acrylamide)] (PNIPAAm-co-MBA) graft copolymer, covalently polymerized to the mesh-gold substrate, caused the conversion of the inert plastic into a thermoresponsive material, resulting in the first PP implantable mesh with both SERS and temperature stimulus responses. AuNPs were homogeneously distributed over the PP yarns, offering a clear SERS recognition together with higher PNIPAAm lower critical solution temperature (LCST ∼ 37 °C) than without the metallic particles (LCST ∼ 32 °C). An infrared thermographic camera was used to observe the polymer-hydrogel folding-unfolding process and to identify the new value of the LCST, connected with the heat generation by plasmonic-resonance gold NPs. The development of SERS PP prosthesis will be relevant for the bioimaging and biomarker detection of the implant by using the plasmonic effect and Raman vibrational spectroscopy for minimally invasive interventions (such as laparoscopy), to prevent patient inflammatory processes. Furthermore, Raman sources have been proved to not damage the cells, like happens with near-infrared irradiation, representing another advantage of moving to SERS approaches. The findings reported here offer unprecedented application possibilities in the biomedical field by extrapolating the material functionalization to other nonabsorbable polymer made devices (e.g., surgical sutures, grapes, wound dressings, among others).

Alginate-assistant nanofiber integrated with polypropylene hernia mesh for efficient anti-adhesion effects and enhanced tissue compatibility

Polypropylene (PP) mesh has been one of the most frequently selected materials for abdominal wall hernia (AWH) repair in the past decades. However, the repair effectiveness is often compromised by the high incidence of adverse events. Improvements are highly desirable to reduce unwanted visceral adhesion and increase tissue integration. Herein, we developed a PP-based composite mesh combined with alginate-assistant nanofiber membrane (NFM) by assembling a large-pore lightweight PP mesh, a NFM barrier consisting of poly (lactic-co-glycolic acid) (PLGA) and polycaprolactone (PCL), and an alginate hydrogel (AH). In vitro studies revealed that the resulting meshes had excellent structural stability, mechanical properties, and biocompatibility. The NFM barriers were firmly attached to the PP substrates, with AH effectively eliminating the delamination without unwanted damage to the nanofiber barrier. In vivo experiments showed that incorporating AH-assistant NFM into PP prostheses could prevent visceral adhesion in an effective manner and promote mesh integration into surrounding tissues from the abdominal wall. These results prove a novel facile and successful strategy to endow prosthetic meshes with superior anti-adhesion capability and tissue compatibility for repairing AWH.

Polypropylene Prosthesis in the Definitive Approach in Failure of Thumb Replantation: Case Report

ARE THERE DIFFERENCES IN CHRONIC PAIN AFTER LAPAROSCOPIC INGUINAL HERNIA REPAIR USING THE TRANSABDOMINAL TECHNIQUE COMPARING WITH FIXATION OF THE MESH WITH STAPLES, WITH GLUE OR WITHOUT FIXATION? A CLINICAL RANDOMIZED, DOUBLE-BLIND TRIAL.

ABSTRACTBACKGROUND:Regarding postoperative pain, it remains unclear whether non-fixation of the polypropylene prosthesis in transabdominal preperitoneal inguinal hernia repair produces the same outcomes as mesh fixation with glue or tackers. In addition, hernia recurrence is another aspect to be assessed in the comparison between non-fixation and mesh-fixation techniques (tackers and glue).AIMS:This study aimed to evaluate the incidence, quality of pain, and recurrence in patients undergoing laparoscopic inguinal hernioplasty (transabdominal preperitoneal) technique, comparing the fixation of the mesh with tackers versus with glue versus without fixation.METHODS:This is a prospective, double-blind study in which 63 patients presenting with primary unilateral inguinal hernia underwent laparoscopic transabdominal preperitoneal inguinal hernia repair and were randomized into three groups: no mesh fixation (n=21), mesh tacked (n=21), and mesh fixed with fibrin glue (n=21). Patients also responded to questionnaires in order to assess pain and pain quality and were followed up for 2 years.RESULTS:Neither mesh-fixation nor non-fixation techniques were found to affect postoperative chronic pain (p=0.535), but patients undergoing tacker fixation reported more pain descriptors (p=0.0021) and a higher pain index (p=0.002) on the McGill scale in the first 15 postoperative days (T0 and T1). No hernia recurrences were observed.CONCLUSIONS:Both mesh-fixation techniques (tackers and glue) used with the transabdominal preperitoneal approach did not influence the onset of inguinodynia, but tacker fixation was more likely to increase patient sensitivity to pain. Mesh placement without fixation produced the same pain and recurrence outcomes as mesh-fixation techniques. Also, no recurrence was observed in patients without mesh fixation in this study. Consequently, it has become an alternative therapy deserving consideration for hernia repair.

RESULTS: - The study was conducted on 48 patients over a period of 2 years from august 2017 to august 2019 after meeting inclusion and exclusion criteria. Their mean age was 45.70 years (range 21-72 years). In our study comparison of preoperative and postoperative values at third and sixth month in the patients did not show any statistically signicant alteration in the variables studied like testicular volume (p-0.987) and blood ow perfusion parameters Peak systolic velocity (p-0.591); End Diastolic velocity (p-0.526); Resistance index (p-0.415). CONCLUSION: - No alteration in testicular volume and arterial ow over a six-month period was observed among patients who underwent laparoscopic extra-peritoneal surgical correction using polypropylene prosthesis for inguinal hernia

Polypropylene prosthesis as cicatricial adjuvant after fasciotomy for compartment syndrome of the foot: Case report

The acute foot compartment syndrome is uncommon and occurs after high energy trauma. Your treatment is considered an orthopedic emergency and a fasciotomy becomes needed. However, after the inicial fase of damage control, the cover up of the incision is necessary. That can be done on the primary moment through parcial skin grafting or delayed primary, through the same technique or through direct suture. As an alternative, this case describes the use of polypropylene prosthesis, inicially described in musculoskeletal trauma of finger tips, as an adjunct to the healing process of foot fasciotomies. The main benefits of this technique are the achievement of one single surgical procedure and the absence of the typical morbidity that comes with skin grafting.

Preventive abdominal wall reconstruction in patients with risk factors of eventration undergoing emergency abdominal surgery

To prevent eventration via preventive abdominal wall reconstruction in patients with risk factors of eventration undergoing emergency abdominal surgery. Treatment results in 120 patients with risk factors of eventration undergoing emergency abdominal surgery were retrospectively analyzed. Patients were divided into 2 groups by 60 people. In the first group, traditional layer-by-layer suturing of the abdominal wall was performed. Preventive abdominal wall reconstruction with a standard polypropylene prosthesis was applied in the second group. We assessed postoperative complications and mortality. The following risk factors of eventration were detected: elderly and senile age (82.5%), long laparotomy (72.5%), decompensated comorbidities (62.5%), widespread peritonitis (52.5%), intestinal obstruction (42.5%), severe internal bleeding (12.5%), disseminated cancer (12.5%), obesity grade 3-4 (10%). In the first group, postoperative morbidity and mortality were 61.7% (n=37) and 13.3%, in the second group - 25% (n=15) and 8.3%, respectively. Preventive abdominal wall reconstruction is advisable in patients with risk factors of eventration.

National survey of surgical practices: Sacropexy in France in 2019.

Sacropexy is a reference surgical treatment for pelvic organ prolapse in women. The great variability in surgical techniques for this procedure is a source of bias that complicates analysis of the results of trials assessing it. Using the French guidelines issued in 2016 by the SCGP, AFU, SIFUD-PP, and CNGOF as a reference, we sought to inventory the surgical practices of the surgeons who perform these procedures. In November 2018, a questionnaire about the technical aspects of this procedure was distributed by email to the French physicians performing it. It was distributed to members of several professional societies (CNGOF, SCGP, and SIFUD) and to gynecologists practicing in clinics owned by the ELSAN group. Of the 273 responders, 92% reported that they perform most operations laparoscopically. Overall, 83% of gynecologic surgeons used polypropylene prostheses (mesh); 38% routinely placed a posterior mesh, while the rest did so only in cases of clinical rectocele with anorectal symptoms. A concomitant hysterectomy was performed by 51% of respondents when the uterus was bulky and/or associated with substantial uterine prolapse. Finally, half the surgeons suggested the placement of a suburethral sling for women with stress urinary incontinence. Although practices are largely consistent with the most recent guidelines, surgical techniques vary widely between surgeons, both in France and internationally.

Biological and microbiological performance of new polymer-based chitosan and synthesized amino-cyclodextrin finished polypropylene abdominal wall prosthesis biomaterial

This study deals with the development of a polypropylene (PP) artificial abdominal wall prosthesis textile with improved biological and antibiotic delivery properties. This added functionality was obtained by finishing of PP prosthesis textile with chitosan (CS), synthesized per-amino-cyclodextrin (CD-NH2) and polyacrylic acid (PAA). The finishing process involved polymerization between the three last mentioned reactants, which generated a cross-linked polymer that coated the PP surface meshes. Then different characterizations were performed on our wash-resistant functionalization to evaluate its efficiency. Firstly, wettability performance, for various grafting rates of the PP biomaterials, was assessed via the drop contact angle technique. Then, a mechanical characterization through an evaluation of the tensile strength revealed no influence of our grafting procedure on these properties. Scanning electron microscopy analysis was performed to evaluate the grafting mode and its effectiveness. Inclusion complex formation between the ciprofloxacin and both CD-NH2 and its polymer were studied via isothermal titration calorimetry measurements. Antibiotic sorption capacities of treated and untreated textile samples were then studied by batch assessments coupled with spectrophotometric analysis. The biological and microbiological properties of the PP mesh functionalized with the CS-CD-NH2 polymer and charged by selected antibiotic were assessed by cell culture analysis. After 3 and 6 days of cell contact, the results revealed an improved proliferation and adhesion of NIH3T3 fibroblastic cells and no obvious cytotoxicity on the chemical functionalized substrate. Finally, in vitro antimicrobial activity of the CS-CD-NH2-grafted PP biomaterial previously loaded with antibiotic was evaluated against the different bacteria strains, Staphylococcus aureus, Enterococcus faecalis and Escherichia coli. Results revealed a greatly superior activity with the functionalized PP meshes compared to that of the untreated PP within a 24 h batch experiment in human blood plasma medium. In summary, the different results from the present study provide an insight into the efficient performance of CS/CD-NH2 polymer as drug delivery system for various applications in the field of medical biomaterials.

New approach to treatment of ventral hernias of the medial localization

Importance. Functional results of treatment of the ventral hernias of the medial localization after endoprosthetics of the abdominal wall by the standard polypropylene prosthesis remain unsatisfactory because of the limited flexibility of the abdominal wall.
 Purpose. To improve functional results of treatment of patients with ventral hernias of the medial localization by applying a light strengthened endoprosthesis.
 Materials and methods. There was done a comparative analysis of the results of treatment of 60 patients with medial hernias of the anterior abdominal wall. Patients were divided into two groups with 30 people in each group. In the first group over-aponeurotic endoprosthetics of the abdominal wall defect was provided with the use of a standard polypropylene prosthesis with the thread diameter 120 micron, while in the second group there was used a light strengthened endoprosthesis with the thread diameter in the basic zones 90 micron and in the strengthened zones 120 and 90 micron. Effectiveness of treatment in the nearest post-operative period was evaluated by the degree of severity of inflammatory implantation response, and in the long-term period evaluation was done on the base of functional state of the abdominal muscles, quality of life of patients and results of treatment by four point scale. 
 Results and their discussion. Inflammatory exudative response on implantation of the light strengthened endoprosthesis was less and reparative response was 1,1 times higher compare to a standard prosthesis. Endoprosthetics of the abdominal wall with a light strengthened endoprosthesis improved contractility of the abdominal muscles in 1,2 times. Restoration of the functions of the abdominal muscles had a positive influence on quality of life, namely, physical component of health improved by 4,5%, as well as on long-term results of treatment by the increased number of excellent and good results of treatment by 20% and reduction of satisfactory results by 20%.
 Conclusions. The use of a light strengthened endoprosthesis enables to improve the functional results of treatment of ventral hernias of the medial localization.

Morphological changes of a great omentum at implantation of polypropylene and composite prostheses at allohernioplasty

To date, allohernioplasty of giant postoperative ventral hernias retains high postoperative mortality and a significant number of postoperative complications. The purpose of the study is to investigate the possibility of intraperitoneal use of polypropylene and composite implants in allohernioplasty of postoperative giant ventral hernias by studying the morphological changes of the great omentum. The results of surgical treatment of 146 patients with postoperative giant ventral hernias were investigated. To this group of patients with allohernioplasty by the method onlay was performed 22 (15.1%) patients, by the method sublay – 46 (31.5%), by the method inlay – 52 (35.6%), with intra-abdominal placement of the mesh by the method onlay (intraperitoneal onlay mesh) – 26 (17.8%). 32 (21.9%) patients who underwent surgery using the sublay method polypropylene implant was fenced off from the abdominal organs with a great omentum, 22 (15.1%) patients operated on by the intraperitoneal onlay mesh method composite implant was also fenced off from the abdominal organs by a great omentum. In 8 (5.5%) patients from the group of patients who were operated on by the sublay method and in 6 (4.1%) – operated by the intraperitoneal onlay mesh method for 14-18 days patients developed signs of chronic intestinal obstruction, where the cause was postoperative adhesive illness. The study of the effect of polypropylene prosthesis on a great omentum was performed on 8 outbred dogs and 6 outbred mature dogs, who were implanted with a composite mesh unilaterally covered with oxycellulose. The polypropylene implant has been shown to have a greater capacity for the development of adhesive processes. However, if a great omentum to protect this prosthesis from the abdominal cavity then the first zone (active inflammation) spread in 155 microns (increase in the number of blood capillaries of the microcirculatory bed, thickening of the arterioles wall, venous full blood flow, diapedesis of leukocytes through the wall of the blood cells), the second zone (sclerosis) – up to 40 microns (increase in the number of macrophages and lymphocytes. proliferation of fibroblasts). In the future, the structure of the omentum was almost indistinguishable, so with allohernioplasty by the developed method, it was possible to prevent the development of adhesive disease on the intestine. This study confirmed the limited spread of the inflammatory response, which allows the implant of a polypropylene mesh on a great omentum. In the composite mesh, the composite mesh was spliced with surrounding tissues from the side where there was no gel coating, and from the side of the salivary coating, the “readiness” to spread the inflammatory process (vasculitis with pronounced lympho-plasmocytic infiltration of the vessel walls and perivascular ductus), therefore, left it is also necessary to enclose it with a large omentum from intestium.

USE OF PLATELETS RICH PLASMA AS A FACTOR OF THE REDUCTION OF THE RISK OF EARLY POSTOPERATIVE COMPLICATIONS IN PATIENTS WITH POSTOPERATIVE VENTRAL HERNIAS

Non-tensioned allohernioplasty with a polypropylene mesh implant has several disadvantages associated with the local occurrence of non-specific long-lasting inflammatory reactions in response to a foreign body. Excessive exudation in the implantation zone leads to the formation of seromas, requiring puncture aspiration, which significantly increases the treatment time. In the long-term, chronic prolonged inflammatory process leads to the formation of coarse connective tissue, which explains the development of biomechanical complications. Growth factors, introduced by platelet rich plasma (PRP), stimulate the release of regenerative cytokines, reduce local inflammatory manifestations in the integration of homoplastic grafts and reduce the incidence of postoperative complications. Aim: through the use of plasma enriched with platelets reduce the severity of early postoperative complications in patients with postoperative ventral hernias. Materials and methods. A clinical study was performed in the surgical department of the center for reconstructive and restorative medicine (university clinic) of the Odessa National Medical University (ONMedU) in the period from 2013 to 2019: 84 patients were operated because of postoperative ventral hernia. The average age of patients was 60.1±7.6 years. The size of hernial defects was on average 8.2 cm. The average BMI was 31.8 kg/m2. According to indications, patients underwent a standard surgical extent of intervention: hernia repair, allohernioplasty of the anterior abdominal wall with a lightweight (80 g/m2) polypropylene implant. After the plastics of the main group, a prosthesis implantation zone was infiltrated with activated autologous PRP, which was prepared by double centrifugation, in a volume of 14–38 ml. There was a control group in which PRP infiltration was not performed. The cavity above the mesh implant was actively drained by Redon for 2–4 days. An ultrasound examination was performed and, if necessary, fine needle aspiration of serous fluid over the mesh was done. Results. The evaluation of the postoperative period (up to 28 days) in patients of both groups. In none of the cases were manifestations of allergic, pyrogenic, local inflammatory or infectious complications. According to the quantitative assessment of early postoperative complications as well as the assessment of the degree of pain syndrome subjectively, according to VAS, the postoperative period in the main and control study groups was almost identical. The need for puncture aspirations and the total volume of discharge was significantly less in the main study group. The dependence of the severity of the effect of the proposed technology on such factors as the size of the hernial defect, the nature of plastics, and body mass index was noted. The greatest efficacy was demonstrated in the group of patients undergoing plastic surgery with the placement of a mesh implant in direct contact with subcutaneous fatty tissue for large-sized hernias (W2+) in the presence of concomitant obesity. Conclusions: the risk of development and the severity of fluid accumulations in the area of allohernioplasty can be predicted taking into account such risk factors as the size of the hernial defect, the nature of plastics, the presence of concomitant pathology, overweight. The technique of soft tissue infiltration in contact with a polypropylene prosthesis is safe, without significantly increasing the risk of local or systemic complications. The proposed method significantly reduces the risk of development and the severity of fluid accumulations in the area of implantation of the prosthesis. The effectiveness of technology is significantly higher compared to groups of patients with a high risk of seromas formation.
