Abstract:
Objective To examine the effect of carbon dioxide pneumoperitoneum on local pancreas pathological changes, serum levels of amylase, IL-6, E-selectin and P-selectin in rats with severe acute pancreatitis (SAP). Methods Fifty healthy male SD rats were randomly divided into 3 groups: CO2 experiment group ( n =20): SAP was induced by injecting 5% sodium taurocholate through retrogradely common biliopancreatic ducts via duodenal papilla,and then CO2 pneumoperitoneum was established at a pressure of 12 mmHg for 30 min; SAP group ( n = 20): The rats were treated as same as CO2 experiment group, excepting CO2 pneumoperitoneum; Control group (n = 10): Abdomen was incised and nothing was done to duodenum and pancreas except for moving them softly. The blood samples were gathered for examining serum levels of amylase, IL-6, E-selectin and P-selectin, and histopathologic examination of pancreas was done.Results Compared with control group, the pancreatic pathologic histology score, serum levels of amylase,IL-6, E-selectin and P-selectin were significantly higher in the CO2 experiment group and SAP group (P =0.000). The levels of IL-6 were significantly lower in CO2 experiment group compared to SAP group (P =0. 000). There was no significant difference between CO2 experiment group and SAP group in pancreatic pathologic histology score( P =- 0.294), the levels of serum amylase ( P = 0.073 ), E-selectin and P-selectin. Conclusions CO2 pneumoperitoneum has no adverse effect on the changes of pathological histopathology and the levels of IL-6, E-selectin and P-selectin in SD rats with SAP.
