Fibrin sealant fixation leads to a low rate of hernia recurrence and avoids tissue trauma. ST provide similar results in the hand of the expert but bear inherent risks of complications due to tissue perforation.
Our objective was to evaluate the role of the liver for procalcitonin (PCT) and cytokine induction in a baboon endotoxin shock model. Complete liver resection with portocaval anastomosis was established in a baboon prior to the induction of endotoxin shock by intravenous administration of endotoxin (100 microg/kg LPS Escherichia coli). Two baboons without surgical intervention were used as controls. Plasma concentrations of PCT, tumor necrosis factor (TNF)-alpha, interleukin (IL) 6, IL-8, endotoxin, and hemodynamic and metabolic parameters were measured pre- and postoperatively and until 6 h after endotoxin administration. PCT concentrations increased to 1.2 and 4.6 ng/mL in control animals at 6 h, but remained below 0.3 ng/mL in the anhepatic baboon. IL-6 and IL-8 increased only for few hours in controls, but remained elevated in the hepatectomized animal near their maximum (IL-6, 2-6 ng/mL) or several-fold higher (IL-8, 30-35 ng/mL), whereas TNF-alpha response was only a small fraction (0.3 ng/mL) of the controls. Endotoxin was much higher and longer persisting in the hepatectomized animal compared with controls. The near absence of PCT production in the anhepatic baboon suggests a primary role for the liver as a source of PCT production during endotoxin shock. Furthermore, the liver also seems to be an important source of TNF-alpha, but not IL-6 or IL-8.
Zusammenfassung. Grundlagen: Die Art der Fibrinkleber (FS)-Applikation trägt wesentlich zu den Vorzü gen dieser Methode, um Herniennetze zu fixieren, bei. Obwohl in zahlreichen Studien belegt werden konnte, dass die punktförmige Applikation von FS ausreichende Festigkeiten und Elastizität gewährleistet, erschien die Sprayapplikation von FS als wesentliche Verbesserung. Diese Studie sollte die Sicherheit und den Anwendungskomfort eines neuartigen FS-Spraysystems mit abgewinkeltem Sprü hkopf in einer 1-jährigen klinischen Anwendungsbeobachtung testen.Methodik: Nachdem die schriftliche Zustimmung eingeholt wurde, wurden bei 27 Patienten 33 primäre Leistenhernien in TAPP-Technik versorgt. Das makroporöse TiMesh (GfE, Deutschland) wurde mit 2 ml FS (Tissucol + ) mittels eines neuartigen Spraysystems mit abgewinkeltem Sprü hkopf fixiert. Der Sprü hkatheter kann ü ber einen 5 mm-Trokar eingefü hrt werden und verfü gt ü ber eine separate CO 2 -Zufuhr. Der Beobachtungszeitraum war 1 Jahr.Ergebnisse: Die Bedienung des Spraysystems war einfach und ergonomisch zufriedenstellend, und es wurden keine Komplikationen im Zusammenhang mit dessen Anwendung beobachtet. Der Sprü hkegel des FS war gut sichtbar, und es wurden keine Serome gefunden. Die Patienten entwickelten keinen chronischen Schmerz, und es kam innerhalb des einen Jahres zu keinem Rezidiv. 2 ml fü r unilaterale bzw. 4 ml FS fü r bilaterale Hernien waren ausreichend.Schlussfolgerungen: Das neuartige Spraysystem mit abgewinkeltem Sprü hkopf stellt eine klare Verbesserung gegenü ber den bisher erhältlichen Fixationsmethoden dar. Die Anwendung ist einfach und ermöglicht eine erhebliche Reduktion der zur Netzfixation notwendigen FS-Menge. Eine Reduktion der Rate der Serome sowie eine Kostensenkung erscheinen so möglich.Summary. Background: The method of fibrin sealant (FS) application for hernia mesh fixation is essential to obtain its full benefits and advantages (i.e., the reduction of chronic pain). In several studies on hernioplasty, punctual mesh fixation with FS proved to be efficient in terms of fixation strength and elasticity and it was hypothesized that an angled tip laparoscopic spray system (LSS) would improve and facilitate the application of the sealant. The aim of the study was to examine the safety and handling of LSS as well as the one-year outcome.Methods: After informed written consent was obtained, transabdominal preperitoneal hernioplasty (TAPP) was performed in 33 primary inguinal hernias in 27 non-selected consecutive patients by a single surgeon. A macroporous mesh (TI-Mesh + , GfE, Germany) was fixed with 2 ml of FS composed of 1 ml of fibrinogen and 1 ml of thrombin (Tisseel + ¼ Tissucol + ). The FS was applied using a newly developed angled spray catheter insertable through a 5 mm trocar and attached to a CO 2 regulator device. Patients were followed up for one year.Results: The angled tip allowed targeted distribution of FS by minimal movements of the device and was safe. The spray cone was always clearly visible during application. At 3 and 12...
