Abstract
OBJECTIVE: To evaluate the value of ischemic preconditioning in clinical hepatectomy. METHODS: A total of 48 unselected patients undergoing liver resection were analyzed by randomized controlled trial from December 2004 to June 2006. Forty-eight unselected patients were randomized into two groups: IP group (5 minutes of ischemia followed by 5 minutes of reperfusion) and control group (received Pringle's maneuver no and no IP was given). Postoperative days 1, 3 and 7, the liver function were checked. Perioperative mortality, morbidity and hospitalized days were compared. RESULTS: In IP group, ischemic times were 5 - 80 min, mean 31 min, hospitalized days were 13 - 50 days, mean 20 days. In control group, ischemic times were 10 - 60 min, mean 27 min, hospitalized days were 10 - 33 days, mean 17 days. Forty-seven patients were satisfactory with postoperative recovery, except one patient died of chronic liver dysfunction after 3 months postoperatively. Postoperative days 1, 3 and 7, the ALT, AST, TBIL, ALB levels in two groups were not statistically significant (P > 0.05). CONCLUSIONS: The clinical use of IP through 5 minutes of warm ischemia in this technique of hepatectomy does not protect the liver from hepatic injury induced by the IRI.
