Hemostasis and hemostatic agents in minimally invasive surgery

As minimally invasive surgery (MIS) has grown in scope and complexity, new challenges have been introduced along the way, including the need for endoscopic hemostatic techniques. Traditional electrical and mechanical means are still the mainstay, but new technologies for hemostasis continue to emerge. Restricted access to the operative site can limit the use of some tools, and yet multiple chemical hemostats and tamponading agents are used in MIS today. Systemic agents also have been developed and have a role in certain MIS circumstances. These products allow surgeons to continue to approach more difficult procedures using minimally invasive techniques. On the horizon are the newer, even less-invasive approaches of natural orifice endoluminal and transluminal surgery, which will increase the difficulties with reliable hemostat agents and delivery mechanisms.
