Opis:
In the therapy of an inguinal hernia, there is a huge variety in the way of treating and the choice of surgical technique. Practice shows that the intraoperative improvisation and surgeons’ own modifications of the original techniques have become part of routine procedure. No mandatory hernia registration system causes the actual detailed herniology status in our country remains unknown. The aim of the study was to summarize the results of a survey on knowledge of a hernia according to the standards developed by international hernia societies compared with everyday clinical practice. During the International Conference Hernia in Poland, which took place on 10 December 2016 in Zakopane we conducted an interactive session among 106 surgeons dealing with hernias. Surgeons responded to 66 questions about daily surgical practice and decision making in their centers, and 27 questions for the assessment of the world’s latest treatment recommendations regarding groin hernias. The most common method of using the implant technique Lichtenstein, used by 91% of doctors. 20% of surgeons in planned operations in adult men routinely uses no mesh technique. Almost 80% of respondents do not apply TEP or TAPP. Only 45.7% of surgeons customize surgical technique to the patient. Only 7 of the 27 analyzed recommendation has been accepted by more than 90% of respondents. 9 of the 27 recommendations were approved by less than half of the surgeons. In the case of 11 recommendations, surgeons simultaneously failed to comply with these recommendations in daily practice. Deficiencies in the system of training and the underfunding of medical procedures cause insufficient TAPP/ TEP availability in Poland in an inguinal hernia. Improvement of the surgeons’ knowledge on how to perform surgery

Opis:
Incisional ventral hernia occurs after almost every fourth laparotomy. Still, both simple suturing of the hernia defect and open mesh repair, lead to a high incidence of infections and recurrences. In recent years, we have observed a further evolution of operational techniques used in order to reduce the number of complications. The search for effective repair methods is currently going in two directions: on the one hand, techniques to reduce tissue tension in the suture line are being developed and disseminated (including modifications to the so-called Ramirez technique); on the other hand, minimally invasive techniques are introduced that allow placement of large synthetic meshes without the need for extensive tissue dissection using open repair. In the first group of presented techniques, emphasis is put on basics and access in the following repair method: original Ramirez technique, modified Ramirez technique, anterior component separation with periumbilical perforator-sparing, endoscopic anterior component separation and transversus abdominis release. In the second part of the manuscript, attention is drawn to the following hernia repair techniques: eTEP, reversed TEP, MILOS/eMILOS, stapler repair, TAPP, TARUP, TESLA, SCOLA, REPA, LIRA, IPOM, IPOM-plus. When choosing the optimal technique for a given patient, the surgeon should first of all be guided by technical feasibility, availability of materials, their own experience, as well as the characteristics of the patient and overall burdens. Nevertheless, surgeons undertaking reconstruction of the abdominal wall in the case of hernias should know different surgical accesses and individual spaces of the abdominal integument, in which a synthetic material may be placed. However, it should be emphasized that poor ergonomics of novel techniques, complex anatomy and complicated dissection of space, as well as the need for laparoscopic suturing in a difficult arrangement of tissue layers and in a narrow space, without a full triangulation of instruments, make these operations a challenge even for a surgeon experienced in minimally invasive surgeries.

Opis:
In laparoscopic operations of abdominal hernias some recurrences still take place, even when applying a surgical mesh. This is usually caused by a failure of the connection between the tissue and the implant. The study deals with the influence of an implant’s orientation on forces in joints, which connect the mesh to human tissues. In the paper, the implant is modelled as a membrane structure within framework of the Finite Element Method. Two models are analysed: in the first one interaction between the mesh and a fascia is taken into account, in the second this interaction is not considered. Computations are conducted for two different material types of the implants: one with isotropic properties and second one with orthotropic properties. The models are validated by comparing dynamic numerical analysis with experimental outcomes, where load was simulating intraabdominal pressure during postoperative cough. Due to displacements of joints during activities like bending sideways or torsion of an abdomen, influence of kinematic extortions on forces in the joints is analysed. The outcome shows that position of the orthotropic implants is crucial and may strongly change the level of forces in the joints.

Opis:
This paper studied the relationship between the textile structure of warp knitted hernia repair meshes and their physico-mechanical properties to solve the problem of hernia patch application evaluation and clear the mechanism of hernia patch structure-performance for clinical application. Six different prototypes of large pore meshes were fabricated, including four kinds of meshes with different pore shapes: H (hexagonal), D (diamond), R (round) and P (pentagonal); and two kinds of meshes with inlays: HL (hexagonal with inlays) and DL (diamond with inlays), using the same medical grade polypropylene monofilament. All meshes were designed with the same walewise density and coursewise density. Then the influence of other structural parameters on the physico-mechanical properties of the meshes was analysed. The physico-mechanical properties of these meshes tested meet the requirements of hernia repair, except mesh DL, whose tear resistance strength (12.93±2.44 N in the transverse direction) was not enough. Mesh R and P demonstrated less anisotropy, and they exhibited similar physico-mechanical properties. These four kinds of meshes without inlays demonstrated similar ball burst strength properties, but mesh HL and DL exhibited better ball burst strength than the others. All in all, uniform structures are expected to result in less anisotropy, and meshes with inlays, to some extent, possess higher mechanical properties. And the ratio of open loop number to closed loop number in a repetition of weave of fabric has marked effect on the physico-mechanical properties. Thus we can meet the demands of specific patients and particular repair sites by designing various meshes with appropriate textile structures.
W pracy przeanalizowano zależność między strukturą chirurgicznych siatek przepuklinowych a ich właściwościami fizyczno-mechanicznymi. Opracowano sześć różnych prototypów siatek o dużych porach, w tym cztery rodzaje oczek o różnych kształtach porów: H (sześciokąt), D (romb), R (okrąg) i P (pięciokąt); oraz dwa rodzaje oczek z inkrustacją: HL (sześciokątne z inkrustacją) i DL (romb z inkrustacją), z wykorzystaniem tego samego monofilamentu z polipropylenu klasy medycznej. Wszystkie oczka zostały zaprojektowane z taką samą gęstością. Następnie analizowano wpływ pozostałych parametrów strukturalnych na właściwości fizyczno-mechaniczne oczek. Właściwości fizyczno-mechaniczne badanych siatek spełniają wymagania, z wyjątkiem siatki DL, której wytrzymałość na rozdarcie (12,93 ± 2,44 N w kierunku poprzecznym) nie była wystarczająca. Siatki R i P wykazywały mniejszą anizotropię i podobne właściwości fizyko-mechaniczne. Powyższe cztery rodzaje siatek bez inkrustacji wykazywały podobne właściwości wytrzymałości na pękanie, a siatki HL i DL wykazywały lepszą wytrzymałość na rozerwanie niż pozostałe. Stwierdzono, że jednolite struktury charakteryzują się mniejszą anizotropią, a siatki z inkrustacją, do pewnego stopnia, mają lepsze właściwości mechaniczne.
