Changes in the Th1/2 ratio in surgical patients with respect to operative procedure. (Black squares – gastric resection (n = 40), black circles – colorectal resection (n = 34), black triangles – hepatic resection (n = 20), white squares – laparoscopic cholecystectomy(n = 12)). The Th1/2 ratio in all groups decreased significantly on POD 2 and significant differences were noted between malignancy group and LC group. However, the ratio in all groups recovered to preoperative levels on POD 14.
