Quantitation of lung sealing in the survival swine model

Use of an electrothermal bipolar tissue sealing system in lung surgery☆

“…The good results obtained in smaller bronchi were confirmed by the assessment of suture margins after wedge resection was performed by the system; the sealing capacity of lung tissue was adequate even with large size resections, reaching a weight of 1.4 g. These results indicate that LigaSure is a suitable system for wedge lung resection. They confirm the conclusions of a study by Tirabassi et al [12] based on the swine survival model; these authors found that sealing of lung tissue by this system was similar to that by endoscopic staplers, and the burst strengths of lung resection margins obtained with both the methods were equal to that of normal lung tissue. As expected, our results suggest that this sealing system is not suitable for the suture of large bronchi, as is required in the case of major lung resections.…”

“…The experience with LigaSure system is limited, particularly in thoracic surgery [11][12][13][14]. Our study is the first biphasic evaluation of this tissue sealing system, both preclinical on 28 pig lungs and clinical on 32 patients.…”

Use of a novel vessel‐sealing device for peripheral lung biopsy and lung lobectomy in a cadaveric model

“…Comparing the LigaSure and endoscopic staplers, Tirabassi et al . () were able to demonstrate in pigs that there was no difference in burst strength at 7 days after surgery. Similar results were found in humans when comparing the LigaSure with an endoscopic stapler in a clinical setting (Kovacs et al .…”

“…VSDs are now not only used to seal vessels, they are also commonly used for simple dissection of tissue (Steffey et al 2015a(Steffey et al , 2015b, splenectomy (Rivier & Monnet 2011), sealing of the cystic duct (Marvel & Monnet 2014) and pericardectomy ), as well as for biopsy of the liver (Barnes et al 2006), pancreas (Mayhew 2009) and lung (Mayhew et al 2012, Marvel & Monnet 2013. In addition, there are a few reports of the use of VSDs for liver lobectomy (Risselada et al 2010) and partial lung lobectomy (Molnar et al 2004, Tirabassi et al 2004, Santini et al 2006, Cakan et al 2009, Koga et al 2014.…”

Simulation study of susceptibility gradients leading to focal myocardial signal loss

“…This is in contrast to the porcine study's conclu sion that the heart–lung interface is responsible for the focal artifact in that the effect of the heart–lung interface appears to be more widespread. However, it should be noted that the simulation assumes that the lungs are homogeneous structures, yet real lungs are divided into discrete sections with differing lobar structures for humans and pigs (14,26). The fissures between sections of lung may possibly contribute to a focusing of the signal loss due to variation in the geometry and tissue involvement of the heart–lung interface at specific locations along the myocardium of humans and pigs.…”
