Cytokine analysis was performed using the Randox Evidence Investigator biochip arrays. (A) IL-6 levels were significantly (*P<0.05) increased in the immediate post-operative period (days 1 and 3), but the levels returned to normal by post-operative day 7; (B) there was no significant change in post-operative IL-8 expression (P=NS); (C) VEGF levels were significantly (P<0.05) elevated postoperatively up to post-operative day 28, after which the levels declined.
