Effect of a Perioperative Oral Nutritional Supplementation on Patients Undergoing Hepatic Surgery for Liver Cancer (IMPACT)

In patients undergoing hepatic resection for liver cancer (with cirrhosis or fibrosis liver), mortality rate can reach 10% and morbidity (ascites, icteria, infections) 70%. These complications are mainly due to hepatic insufficiency: surgery leaves a reduced parenchyma, with oxidative stress lesions due to reperfusion injury. A good preoperative nutritional state has been shown to reduce complications and mortality. This can be amplified by preoperative nutrition with supplements containing L-arginin, ω3 polyunsaturated fatty acids, and nucleotides which boost immune responses, resistance to infections and liver function recovery. In this context, the study randomly assigns 50 patients who were scheduled to undergo hepatic resection, to receive either an oral immune-enhancing nutritional supplement or a placebo, for the 7 last preoperative and the first 3 postoperative days. The aim of the study is to evaluate the effects of this supplementation on liver function, immunity, and incidence of infections after surgery.
