Background: During cholecystectomy, the bile duct may be injured. When this complication occurs, Kupffer cells are activated and produce tumor necrosis factor alpha (TNF-α) and interleukin-6 (IL6) to phagocyte toxic products

Aim: To measure serum levels of TNF-α and IL-6 among patients that suffered a bile duct injury after a cholecystectomy.

Patients And Methods: Serum levels of TNF-α and IL-6 were measured prior to the bile-enteric derivation and after one year of follow up, in 31 patients that had a complete bile duct obstruction after open or laparoscopic cholecystectomy and in 5 healthy controls.

Results: At baseline TNF-α levels in healthy subjects and patients with bile duct injury were 0 and 43.9 ± 2.9 ng/mL, respectively (p < 0.01). At one year of follow up, TNF-á became undetectable among patients. At baseline, the values for IL-6 among healthy controls and patients were 3.0 ± 2.0 and 72.0 ± 94.7 pg/mL respectively, (p < 0,004). After one year of follow up, IL-6 levels decreased to 6.4 ± 0.3 pg/mL among patients.

Conclusions: TNF-α and IL-6 levels were elevated before bile-enteric derivation among patients with bile duct injury and became normal one year later.
