Selective continuous vascular occlusion and perioperative fluid restriction in partial hepatectomy. Outcomes in 101 consecutive patients.

Background: This study documents patient outcomes with one department's approach to performing partial hepatectomy.

Methods: 101 consecutive patients underwent: preoperative dehydration; intraoperative CVP <5 cm H(2)O and selective continuous vascular occlusion.

Outcome Variables: pathology; type of hepatic resection; intraoperative blood loss and transfusion rate; 30 day morbidity and mortality; disease free and long term survival. Perioperative liver function was assessed by serial blood sampling.

Results: Of 101 resections: 90% malignant disease; 59% major resections and 35% synchronous procedures. Median estimated blood loss was 400 mL (mean 512 mL, range 50-3000 mL) with postoperative transfusions in 4%. Thirty day morbidity was 20% with no deaths. Median time to local recurrence after colorectal liver metastases resection was 17.1 months with 3 year survival of 51%. Distinct perioperative changes in hepatic function were seen.

Conclusion: Selective continuous vascular occlusion and perioperative fluid restriction result in minimal blood loss, low morbidity and zero mortality in patients undergoing partial hepatectomy.
