Laparoscopic ovariectomy in dogs: a comparison of the LigaSure™ and the SonoSurg™ systems

Abstract

Both the SonoSurg™ and the LigaSure™ devices appear to be effective, safe and easy to use when performing laparoscopic ovariectomy in dogs.

Cordless ultrasonic dissector versus advanced bipolar vessel sealing device for laparoscopic ovariectomy in dogs*

“…The technique of laparoscopic ovariectomy (Lap OVE) in dogs has improved with the development of advanced endoscopic vessel sealing and tissue dissection technologies . These devices use a grasping forceps that create a tissue seal by a combination of pressure and thermal heating.…”

Vessel sealing versus suture ligation for canine ovarian pedicle haemostasis: a randomised clinical trial

“…Previous studies evaluated different techniques for ovarian pedicle haemostasis in laparoscopic OVE procedures in dogs (van Nimwegen and others 2005, Mayhew and Brown 2007, van Nimwegen 2007, Öhlund and others 2011), amongst which VSDs have successfully been used. They not only do reliably seal large vessels (up to and including 7 mm), but also rely on a feedback-controlled response system that automatically discontinues the electrocoagulation process when the tissue is adequately sealed (Richter and others 2006).…”

“…In laparoscopic OVE, different techniques for ovarian pedicle haemostasis have been evaluated and compared: extra-corporeal or intra-corporeal SL, vascular clips, monopolar and bipolar electrocoagulation, laser energy and VSDs (Harold and others 2003, van Nimwegen and others 2005, Mayhew and Brown 2007, van Nimwegen 2007, Öhlund and others 2011). …”

Facilitation of Soft Tissue Surgery

“…47 Studies to examine the effectiveness and speed of these devices in procedures, collateral damage to tissue, blood loss, and use in minimally invasive surgery have been done and support their use in veterinary surgery. 22,40,45,46,[48][49][50][51][52] Benefits that have been noted include efficient and complete hemostasis of vessels, adequate arterial bursting pressure, absence of foreign material, and no need for additional ligation support. 44 In a study by Rivier and Monnet,44 it was determined that use of a vessel sealant device (Ligasure) provided adequate hemostasis and would provide adequate resistance to blood pressure in splenectomies when the splenic vessel and other associated vessels were isolated and coagulated.…”
