Patients who undergo LH have similar short-term outcomes when compared with those who undergo OH. Laparoscopic hepatectomy was associated with lower intraoperative blood loss, although the clinical significance of this finding is uncertain given the lack of difference in perioperative transfusion or morbidity rates. In addition, we found no difference in margin status between the 2 groups. Future studies are needed to define which patients derive benefit from LH and to determine oncologic equivalence to OH.

Despite increased use of acute hemodilution (AH) to reduce perioperative blood transfusion in patients undergoing partial hepatectomy, there is a lack of data on safety in those with comorbid medical illness. We performed a retrospective review of 96 patients undergoing partial hepatectomy with AH and low central venous pressure (CVP) anesthesia. The cohort was compared with 63 patients undergoing partial hepatectomy using standard anesthetic management (SA) and low CVP anesthesia. All were American Society of Anesthesiologists physical status 3 or 4. 58 per cent were baseline hypertensive on medication. Hepatic resection was predominantly performed for metastatic colorectal (41%) and primary hepatic (32%) cancer. Forty per cent underwent major hepatectomy. The mean volume of blood removed for AH was 497 mL (range, 0 to 1 L). Most achieved low CVP (AH 90% vs SA 84%, P = 0.3). Blood loss was lower with AH (mean 480 mL vs 904 mL, P < 0.001). Blood transfusion rate was 74 per cent lower with AH ( P < 0.001). There was no difference in cardiac, respiratory, renal, or overall complications with AH compared with SA. Acute hemodilution is well tolerated by patients with comorbid illness undergoing partial hepatectomy, favoring ongoing use and further study.

A low platelet count on POD 5 was associated with graft loss and mortality after LT. Platelet count <72 500/μL on POD 5 can be a predictor of poor graft and overall survival. Maintaining higher postoperative platelet counts could potentially improve graft and overall survival rates.
