Reducing inflow occlusion, occlusion duration and blood loss during hepatic resections.

BACKGROUND: To assess the changes in blood loss during hepatic resection with improved haemostatic devices such as a bipolar sealing device and a topical haemostatic agent.

METHODS: This retrospective clinical study of prospectively collected data will assess hepatic resections performed by a single surgeon between 2005 and 2013, with the introduction of the two haemostatic techniques in 2009.

RESULTS: A total of 371 hepatic resections (214 from 2005 to 2008 and 157 from 2009 to 2013) were included in this study. Compared with the conventional hepatic resection (2005-2008), the use of haemostatic techniques (2009-2013) significantly reduced the need for inflow occlusion (OR: 0.37, 95% CI: 0.24-0.57, P < 0.001), overall occlusion time (20.8 min versus 25.9 min, P = 0.04) and transfusion requirement (4.6% versus 12%, OR: 0.35, 95% CI: 0.14-0.90, P = 0.02). Mean overall blood loss was reduced post-2009; however, the decrease was not statistically different (401.3 mL versus 470.8 mL, P = 0.27). Subgroup analysis revealed that blood loss was more than halved post-2009 compared with pre-2009 for patients who received pre-operative chemotherapy (324.6 mL versus 738.5 mL, P = 0.005).

CONCLUSION: The use of a bipolar sealing device and a topical haemostatic agent reduces the need for inflow occlusion, overall occlusion time and transfusions in all patients compared with conventional hepatic resections.
