Introduction:
It's been demonstrated laparoscopic access determines a lower surgical stress, by measurement of several markers as different interleuquines (IL) or C-reactive protein (CRP). Endothelin 1 (ET-1) is a powerful vasoconstrictor produced in renal endothelium scarcely studied in laparoscopy. The objective of this study is to analyze immune response during laparoscopic and open donor nephrectomy, in a porcine experimental model by means of measuring IL-2, 10, tumoral necrosis factor alpha (TNFalpha), CRP and ET-1.
Methods:
Twenty pigs underwent left nephrectomy, 10 by laparoscopy and 10 by open approach in an experimental model. Both groups were monitorized IL-2, 10, TNF alpha, ET-1 at basal, immediately post surgery, first, third, fifth and seventh days after procedure.
Results:
The comparative analysis between groups demonstrated a significant increase in levels of CRP (1.44+/-0.88 vs 1.32+/-0.14 mg/dl, p=0.046), TNF alpha (131.14+/-41.37 vs 57.19+/-23.71 pg/ml, p>0.001) and ET-1 (0.91+/-0.49 vs 0.56+/-0.5 fmol/ml, p=0.001) of open nephrectomy group, as a higher levels of IL-2 in laparoscopic group.
Conclusions:
Open donor nephrectomy determines a higher immune response than laparoscopic approach. The importance of this fact over the ischemia-reperfusion syndrome or the immediate function of graft is not clearly established.
