COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Hemihepatic Vascular Inflow Occlusion group (In hemihepatic vascular inflow occlusion, the portal vein, hepatic artery, and bile duct were dissected in the hilum by lowering the liver plate. Either the right or left portal pedicle was isolated en bloc and was controlled with a tourniquet or Santinsky clamp. The estimated duration is around 30 minutes.)
Portal Vein Inflow Occlusion group (In portal vein inflow occlusion, the portal vein was isolated and occluded with a tourniquet. The estimated duration is around 30 minutes.)
Intervention code [1] 4380 0
Treatment: Surgery
Comparator / control treatment
Pringel Maneuver group (In Pringle maneuver group, the entire hepaticoduodenal ligament was encircled and tightened with a rubber tourniquet. The estimated duration is around 30 minutes.)
Control group
Active

Summary
Brief summary
The impact of blood loss during liver resection and the need for perioperative blood transfusions have been shown to negatively impact perioperative morbidity and mortality as well as long term outcomes. The objective of this study is To compare the perioperative outcomes of partial hepatectomy using hemihepatic vascular inflow occlusion, portal vein inflow occlusion. and Pringle maneuver.
