To report our novel triphasic approach to minimising blood loss during hepatic resection and the renal sequelae.Fifty consecutive patients (median age 63.3 years, range 37–86) underwent hepatic resection. Triphasic approach consisted of: pre-operative bowel preparation with no supplementary fluids; intraoperative intravenous fluid restriction with low central venous pressure (<5cmH 2 O) and continuous selective occlusion of the left or right portal structures and corresponding hepatic vein/s. The following variables were analysed: blood loss; transfusion requirements; perioperative renal function; perioperative morbidity and mortality.Median estimated blood loss was 330mL (range 50–1200). No patient was transfused intraoperatively, with two patients transfused post-operatively. Median intraoperative urine output prior to hepatic re-perfusion was 28.4mL/h (range 13.3–40.0) with no patient developing renal impairment. Morbidity occurred in 22% of patients with no documented hepatic failure. There was zero 30-day mortality.Pre-operative dehydration and intraoperative fluid restriction combined with continuous selective vascular occlusion minimizes blood loss during hepatic resection with no consequent detriment to renal function.
