Objective To research the changes in plasma endothelin, LPS, TNF-α, IL-6 and IL-8 in the patients with obstructive jaundice (OJ) and non-obstructive jaundice (NOJ) after surgery. Methods The plasma ET, LPS, TNF-α, IL-6 and IL-8 were measured in 15 patients without jaundice as controls. Results As compared with NOJ, the postoperative changes of ET, LPS, TNF-α, IL-6 and IL-8 in OJ group increased significantly at multiple time points (P＜0.05). Conclusion There is interaction between ET,LPS, TNF-α, IL-6 and IL-8 and damage to multiple organ function in patients with OJ after surgery.
