Summary
Liver resection is an operation to remove the diseased part of the liver. The liver is supplied by two vessels, the hepatic artery and the portal vein supplying 25% and 75% respectively of the total blood flow with 50% oxygen from each vessel. During liver resection it is standard practice to clamp both vessels(Pringle's manoeuvre), so as to avoid bleeding. Clamping both the vessels deprives the unaffected liver from nutrients required for survival. Reinstating the blood supply causes further damage by pouring harmful substances into the liver, which accumulate during the clamping. We hypothesize that not clamping the oxygen rich hepatic artery will cause less damage to the liver.

Our aim is to compare the Pringle manoeuvre with portal vein clamping, to identify if the latter will result in less tissue injury and thereby fewer complications. Initially we aim to conduct a pilot study. The main objective is to ensure that patients can be successfully recruited and that data capture is complete. The secondary outcomes will be development of infective complications by 30 days following surgery, bleeding and blood transfusion requirements, heart/chest complications, recovery of liver functions, growth of remnant liver, death within 30 days following surgery, length of high dependency unit/hospital stay and quality of life at 3 months after surgery.

There is published literature on the safety of this method and in the event of any intraoperative problems, the procedure will be converted to the standard Pringle manoeuvre. The Liver Unit at St James's University Hospital has four surgeons performing around 270 liver cancer resections per year, of which nearly 160 are for bowel cancer spread. Considering the team's experience in research and liver surgery, we believe it is well placed to conduct the trial in a safe and efficient manner.
