Eighteen adult male New Zealand rabbits weighing 2.5 to 3.0 kg were randomized into three groups of six rabbits each. Each rabbit was anesthetized with 35 mg/kg of ketamine hydrochloride (Cristalia, Itapira, SP, Brazil) and 5 mg/kg of Xilazine (Bayer, Sao Paulo, SP, Brazil) that was infused through a catheter placed into the auricular vein. The animals were then positioned in the left lateral decubitus position, and their right chest areas were shaved and cleansed with iodopovidone (Rioquimica, S.J. Rio Preto, SP, Brazil). A mask adapted to each rabbits muzzle provided continuous oxygen during the entire experiment. Each rabbit underwent a videothoracoscopy procedure involving a lateral 2 cm skin incision in the right thorax, followed by muscle division and the intercostal insertion of a 5 mm trocar (Thoracoport, Medline, IL, USA) for accessing the right pleural cavity. Another 2 cm medial incision was made to introduce the second port for the lung incision procedure.</p><p id="para50" class="elsevierStylePara elsevierViewall">The treatment groups were as follows: a control group (VATS + lung incision without treatment), an FB group (VATS + lung incision + FB adhesive application - Evicel®; Omrix Biopharmaceuticals, Ethicon, Israel) and a CA group (VATS + lung incision + CA adhesive application - Omnex<span class="elsevierStyleSup">®;</span> Omrix Biopharmaceuticals, Ethicon, Israel). All lung incisions were 1 cm in length and performed in the middle lobe. The amount of sealant applied to each lung incision was 1 mL.</p><p id="para60" class="elsevierStylePara elsevierViewall">Before the trocars were withdrawn, the residual air in the pleural space was completely aspirated, and the skin was sutured with 4-0 monofilament nylon.

The incidence of PAL depends on several factors, such as the presence of damaged or fragile lung parenchyma <a class="elsevierStyleCrossRef" href="#bib13">13</a>, the use of steroids <a class="elsevierStyleCrossRefs" href="#bib12">12–14</a>, whether upper lobectomy is performed <a class="elsevierStyleCrossRef" href="#bib15">15</a>, and the presence of pleural adhesions <a class="elsevierStyleCrossRef" href="#bib16">16</a>. Thus, PAL remains a frequent and challenging complication. To help prevent postoperative lung air leakage, tissue sealants/adhesives can be used.</p><p id="para160" class="elsevierStylePara elsevierViewall">FB is the most common adhesive agent used in surgical practice. As a biological substance, FB allows adequate tissue healing, but concerns about its use have been raised, including its unclear efficiency <a class="elsevierStyleCrossRef" href="#bib17">17</a>,<a class="elsevierStyleCrossRef" href="#bib18">18</a> and the possibility of allergic reactions to its proteins <a class="elsevierStyleCrossRef" href="#bib19">19</a>. In contrast, CA is a synthetic product with known efficiency, although its use also raises concerns, specifically regarding biocompatibility and local toxicity <a class="elsevierStyleCrossRef" href="#bib20">20</a>.</p><p id="para170" class="elsevierStylePara elsevierViewall">The FB tissue adhesive consists of a combination of human plasma fibrinogen, thrombin and an anti-fibrinolytic product. In the presence of thrombin, fibrinogen is converted into a fibrin clot. FB glue has been the most widely used tissue adhesive in thoracic surgery over the past two decades. However, interest in the product has decreased since randomized trials conducted by Fleisher <a class="elsevierStyleCrossRef" href="#bib17">17</a> and Wong <a class="elsevierStyleCrossRef" href="#bib21">21</a>. In these trials, the use of FB in comparison with the control revealed no differences in outcome, number of postoperative air leaks, chest drain duration or length of hospital stay. In a recent systematic review addressing the application of surgical sealants, primarily FB adhesives, after pulmonary resection, the authors concluded that there are decreases in postoperative air leaks and time to chest drain removal and no reduction in the length of postoperative hospital stay <a class="elsevierStyleCrossRef" href="#bib22">22</a>. One of the most important benefits of fibrin sealants is their low inflammation and rapid degradation compared with those of other sealants <a class="elsevierStyleCrossRef" href="#bib23">23</a>. Although some studies have shown that FB sealants allow a superior aerostasis in patients undergoing pulmonary resection <a class="elsevierStyleCrossRef" href="#bib24">24</a>, other studies have reported a lower resistance bonding property of FB sealants compared with that of CA glue <a class="elsevierStyleCrossRef" href="#bib25">25</a>.</p><p id="para180" class="elsevierStylePara elsevierViewall">CA adhesive has shown effectiveness in preventing air leaks, but its use is associated with intense local reactions and no signs of degradation over time <a class="elsevierStyleCrossRef" href="#bib26">26</a>,<a class="elsevierStyleCrossRef" href="#bib27">27</a>. The current study found an intense local reaction to CA applied to lung lesions in rabbits; however, no systemic repercussion, as measured by the response of leukocytes and neutrophils, was observed. Nevertheless, both FB and CA produced an acute elevation of serum IL-8 levels 48 hours after application. To our knowledge, no previous studies have addressed the systemic effects of CA and FB sealants/adhesives applied to lung lesions.</p><p id="para190" class="elsevierStylePara elsevierViewall">Concerning the local reactions to adhesives, the findings of the present study are similar to those of previous reports <a class="elsevierStyleCrossRef" href="#bib23">23</a>,<a class="elsevierStyleCrossRef" href="#bib28">28</a>. The reactions mainly include a pronounced local inflammatory response to CA, with the infiltration of granulocytes, lymphocytes and foreign body giant cells, and minor signs of degradation over time. However, when FB sealant was used, no residual adhesive was found and microscopy analysis revealed adequate tissue healing.</p><p id="para200" class="elsevierStylePara elsevierViewall">CA derivatives have low viscosity, dry rapidly, gain adhesion rapidly and, most importantly, have strong adhesive capability. Among several available commercial formulations, Omnex® represents a long-chain derivative of octyl-cyanoacrylate that polymerizes slowly and gradually releases heat to the injured tissue. In theory, newer formulations of CA are less toxic; however, they are not completely free of the adverse inflammatory properties of previous products. The findings of our study show that CA shows persistent adherence to lung tissue, and after drying, it polymerizes and becomes a very stable and inert compound. A rodent model of CA injection showed that this polymer persisted inside the abdominal cavity up to 12 months after local application <a class="elsevierStyleCrossRef" href="#bib27">27</a>.</p><p id="para210" class="elsevierStylePara elsevierViewall">Although CA does not appear to degrade over time, local toxicity does not appear to be a concern. In a study using electron microscopy, CA showed no inhibition of tissue regeneration and no histotoxicity <a class="elsevierStyleCrossRef" href="#bib29">29</a>. Another study with nanoparticles composed of CA revealed that the substance was stable and showed no toxicity <a class="elsevierStyleCrossRef" href="#bib30">30</a>. In addition, amnion cell cultures from fetal membranes showed no toxicity after exposure to CA <a class="elsevierStyleCrossRef" href="#bib31">31</a>. In another <span class="elsevierStyleItalic">in vitro</span> study using mouse fibroblasts, it was found that when a large number of cells was used, cell proliferation overcame the cytotoxic effect of CA <a class="elsevierStyleCrossRef" href="#bib32">32</a>. Another study with cardiomyoblasts using an extract dilution assessment showed that CA had no toxic effect on the cells <a class="elsevierStyleCrossRef" href="#bib33">33</a>.</p><p id="para220" class="elsevierStylePara elsevierViewall">Regarding the possible systemic inflammatory reaction related to the application of FB or CA to lung lesions, the present study did not find an increase in blood leukocyte, neutrophil or lymphocyte count following application. Montanaro L et al. <a class="elsevierStyleCrossRef" href="#bib34">34</a> found no significant variation in the numbers of total or differential leukocyte counts when CA glue was used. In our study, although the blood cellular profile did not vary among groups, the serum levels of IL-8 increased 48 hours after the application of FB or CA in lung lesions. These results show that the local inflammatory reaction may produce systemic repercussions when more sensitive markers are used than when cellular counts alone are used. The IL-8 levels increased in a similar manner for the two adhesive agents, and the levels of this cytokine decreased at day 28 to levels comparable to those of the control group.</p><p id="para230" class="elsevierStylePara elsevierViewall">In conclusion, either FB or CA applied to the lung lesions of rabbits promoted effective local healing. CA promoted a pronounced local inflammatory response with cell infiltration and the appearance of foreign body giant cells, and FB promoted normal tissue healing.</p><p id="para240" class="elsevierStylePara elsevierViewall">The only systemic effect observed for both agents was an elevation of serum IL-8 levels at 48 hours; these levels had decreased at 28 days after the procedure. These findings may be relevant to surgeons who need to use adhesives as adjuvants to seal complex injuries. In addition, the current study may decrease the concern regarding the potential undesirable adverse effects of CA that have been reported by previous studies.</p></span><span id="cesec110" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cestitle150">AUTHOR CONTRIBUTIONS</span><p id="para250" class="elsevierStylePara elsevierViewall">Carvalho MV and Marchi E conceived and designed the study, they were responsible for the animal procedures, the acquisition and analysis of the data, and the drafting and revision of the manuscript.
