Adjustable laparoscopic surgical device-LARA-KI: a new approach to the posterior segments liver resection-experimental ex vivo study

Original language description

Liver resection is standard treatment method for any liver lesions. Laparoscopic liver resection is associated with lower intraoperative blood loss and less number of complications. The access to the posterior part of liver right lobe is very uncomfortable and inaccessible in use of laparoscopic surgery. With these experiences it was developed new laparoscopic device, which can break its long axis and allows the application of radiofrequency energy in areas that are current technical possibilities so far unavailable. The device is equipped with four telescopic needle electrodes that coagulate tissue after delivery of radiofrequency energy. Ex vivo testing was performed in years 2012 and 2013 at the University Hospital Ostrava on porcine liver tissue. The main goal of the testing was to figure out if the newly proposed electrode layout is suitable for sufficient tissue coagulation and creating a safety zone around lesions. During the ex vivo testing, material of needle electrodes has been improved to achieve the lowest possible of adhesion. The power supply was adjusted from 20W to 120W and monitored the ablation time which varied from 110 to 10 seconds. Subsequently, optimal power delivery and time for coagulation was determined. This experimental study demonstrated the feasibility and safety of the newly developed device. Based on the ex vivo testing, LARA-K1 can create a safety zone of coagulation. For further assessment of the new device, the in vivo study should be performed.
