Brief summary
Severe ischemic changes of the liver remnant after hepatectomy could expedite tumor recurrence on the residual liver. Our study aimed at assessing the effect of warm ischemic/reperfusion (I/R) injuries on surgery-to-local recurrence interval and patient overall survival, during major hepatectomies under inflow and outflow vascular control.
Detailed description
One hundred and eighteen patients were subjected to liver resection under total inflow and outflow vascular clamping and were assigned as study group. These individuals were retrospectively matched to 112 counterparts, who underwent liver surgery applying inflow and outflow vascular clamping only of the segment harboring the tumor, sparing the liver remnant from any I/R injury (control group). The two cohorts were compared regarding recurrence-free survival and overall survival.
Interventions
major hepatectomy with vascular control of blood inflow and outflow of the whole liver
major liver resection by selectively clamping the portal and hepatic vessels only of the lobe harboring the tumor
