“…This limitation is especially relevant in small dogs and cats undergoing minimally invasive surgery. 13 A self-locking resorbable ligation device has recently been found efficacious for ligation of ovarian pedicles, spermatic cords, renal arteries, pulmonary hilus, and cystic ducts in animals. [14][15][16][17][18][19][20][21] This device design was based on that of a cable tie modified to create a relatively inert, resorbable device that can reliably achieve complete hemostasis in soft tissue surgery.…”

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.

“…The procedure can be performed with a thoracotomy or video‐assisted thoracoscopic surgery (VATS). Various stapling devices, ligation clips, vessel sealant devices, and suture loops are used for partial and complete lung lobectomies in animals and man . Airways are most commonly sealed with linear stapling devices in animals.…”

Objective: To compare the maximum pressure sustained by airways sealed with a resorbable ligation device (LigaTie) and with thoracoabdominal (TA) staples during thoracoscopic-assisted hilar lung lobectomies. Study design: In situ cadaveric study. Animals: Ten feline cadavers. Methods: Twenty lung lobectomies were performed with either a LigaTie or a TA stapler (n = 10 per group) by using a thoracoscopic-assisted technique. Procedures were randomly performed on the cranial lung lobes only. The distance between the ligation and the hilus was measured on each specimen. Airway pressures were tested to a maximum pressure of 40 cmH 2 O. Results: All LigaTie sites reached a maximum airway pressure without leaking and were easily placed at the hilus. Four of 10 TA stapled sites leaked at a mean pressure of 22 cmH 2 O (P = .010). All leaks occurred when the TA staple line was >5 mm from the hilus; no leaks occurred when the TA staple line was ≤5 mm from the hilus (P < .001). No difference was found between fresh and frozen cadavers (P = .483) or right vs left lung lobe (P = .284). Conclusion: Lung lobectomies were consistently performed at the hilus only when the LigaTie was used. Lung lobectomies were less likely to leak when performed with the LigaTie rather compared with TA staples. Clinical significance: The LigaTie may be an effective alternative for lung lobectomies at the pulmonary hilus in cats and small breed dogs. Our findings provide justification for additional clinical testing.

Swine have been frequently used for hands-on training in surgery but there are no reports in the literature describing the anatomical, anaesthetic and technical peculiarities that must be observed during videothoracoscopic lobectomy training in swine. Video-assisted thoracoscopic surgery lobectomy using swine is an adequate method to train thoracic surgeons. For surgeons to make the best use of minimally invasive technique training, it is essential that issues related to the anatomy, anaesthesia, monopulmonary ventilation and surgical technique described in this study are taken into account.
