ZHOU, S et al. A comparative study assessing a new tool for occluding parenchymal blood flow during liver resection for hepatocellular carcinoma. S. Afr. j. surg. [online]. 2013, vol.51, n.1, pp.12-15. ISSN 2078-5151.

BACKGROUND: The aim of this study was to compare the efficacy of a new tool (the hepatic section vascular blocker, HSVB) with hepatic pedicle clamping and hemihepatic vascular exclusion to control bleeding during liver resection for cancer. METHODS: Clinical data on 117 patients who underwent liver resection from 2004 to 2009 were analysed retrospectively. Forty-two patients had liver resection using the HSVB (group A), in 35 patients hemihepatic vascular exclusion was used (group B), and in 40 patients hepatic pedicle clamping with a Pringle manoeuvre was used (group C). Blood loss, operative time, postoperative hepatic function and complications were compared. RESULTS: Mean blood loss and operative time in group A were significantly less than in groups B (p=0.026 and p<0.001, respectively) and C (p<0.001 and p<0.001). There were significant differences between groups A and C in total bilirubin (TB) and alanine transaminase (ALT) levels on postoperative days 3 and 7, and group A had better hepatic function (TB p=0.014 and p=0.009; ALT p<0.001 and p<0.001). The rate of postoperative ascites was significantly higher in group C compared with group A (p<0.001). In group C, 2 patients had liver failure, 1 had a gastrointestinal haemorrhage and 1 died. CONCLUSIONS: Using the HSVB during liver resection effectively controlled bleeding, saved operative time and preserved hepatic function. It proved to be a safe and feasible technique.
