“…None of the six seals created by the 12‐mm Caiman VSD leaked below 25 cm H 2 O, resulting in a small safety margin. This compares favourably with the study of Marvel & Monnet () where a single and double seal of the LigaSure resulted in a median leak pressure of 33 cm H 2 O for single and double seals. However, leakage occurred in 25% of the specimens at a pressure below 20 cm H 2 O, leading to the conclusion that the LigaSure is not a safe or reliable method for lung biopsies 3 cm from the edge of the canine lung.…”

“…Minimally invasive surgery has been growing rapidly in recent years and, therefore, vessel-sealing devices (VSDs) are increasingly in demand. 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.…”

Objective To evaluate the Caiman vessel‐sealing device for peripheral lung biopsy and total lung lobectomy in cadaveric canine lung lobes. Material and Methods Twelve lung lobes were randomly assigned to peripheral lung biopsy (n=6) or total lung lobectomy (n=6) with the 12‐mm Caiman vessel‐sealing device. Lungs were connected to a ventilator set at 10 breaths per minute with an initial pressure of 5 cm H2O during the procedure. The lungs were submerged in water for leak testing and the pressure increased until leakage occurred. Results Mean airway pressure at which leakage occurred was 39.17 ±13.20 cm H2O for peripheral lung biopsies and 38.33 ±13.67 cm H2O for total lung lobectomies. None of the samples leaked below 25 cm H2O, which is well above the physiologic airway pressure. Histologically, the largest bronchial diameter at the sealed area was 8.84 mm and the extent of collateral damage was approximately 2.7 mm in all specimens. Clinical Significance The Caiman vessel‐sealing device was successfully used for peripheral lung biopsy and total lung lobectomy in cadaveric canine lung lobes. All sealed lung lobes tolerated supra‐physiologic airway pressure, displayed minimal collateral damage, and were of good diagnostic quality. Further experimental studies are needed to evaluate the clinical safety of the device for peripheral lung biopsy or total lung lobectomy.

“…The lungs were harvested, and testing was performed within 2 hours after euthanasia. The airway leak testing and pressure monitoring were performed as described in previous studies . Briefly, insufflation was performed by inserting an endotracheal tube into the targeted bronchus, the cuff was inflated, and 2–0 nylon suture was tied around the bronchus proximal to the cuff.…”

Evaluation of a resorbable self‐locking ligation device for performing peripheral lung biopsies in a caprine cadaveric model

Objective To compare airway leak pressures after sealing peripheral lung biopsy sites with a resorbable ligation device (LigaTie) or thoracoabdominal (TA) staples. Study design Ex vivo study. Animals Four normal caprine cadavers. Methods Twelve lung lobes were harvested from 4 goats immediately after euthanasia. Each lobe was inflated to 20 cm H2O to test for leaks prior to biopsy. Pressure was then maintained at 10 cm H2O. Biopsy samples were obtained 3 cm from the periphery with a resorbable ligation device or a TA stapler (n = 6 per group). After biopsy, inflation pressure was slowly increased to 40 cm H2O while lungs were submerged in water. The pressure at which bubbles were first seen was recorded as the airway leak pressure. The length, width, volume, and weight were recorded for each biopsy sample. Results Five of 6 LigaTie biopsy sites sustained the maximum pressure of 40 cm H2O without leaking. One site leaked at 24 cm H2O. The TA‐stapled sites sustained airway pressure to median 25.5 cm H2O (interquartile range, 23.5–26 cm H2O), and none of them reached the maximum pressure (P = .015). There were no differences in biopsy length, volume, or weight between groups. Conclusion Biopsy sites sealed with LigaTie withstood higher airway pressure without leaking compared with TA‐stapled biopsy sites in normal cadaveric specimens. Clinical significance The LigaTie may be an alternative technique for sealing peripheral lung biopsy sites.

Abstract: All tested techniques seemed safe except the vessel sealant device since it did not consistently seal every biopsy and leaked at pressures <20 cmH2 O.
