Objective
2
To determine the effect of abdominal paracentesis drainage (APD) on the intestinal bacterial translocation in rats with severe acute pancreatitis (SAP).
Methods
2
The rats were intragastrically fed with
Escherichia coli
whose plasmids were reconstructed with green fluorescent protein (GFP-
E.coli
). These GFP-
E.coli
labeled rats were randomly divided into 3 groups: sham operation group (Sham group)
SAP group and APD group. The SAP rats were estab
lished by retrograde infusion of sodium taurocholate into biliopancreatic duct. The APD treatment was applied by inserting a drainage tube into the right lower quadrant of rats after SAP establishment. Spleen specimens were harvested in a sterile manner along with scarifying the rats in 24 h after operation. Bacterial translocation in the blood
mesenteric lymph nodes (MLNs) and pancreatic tissues
level of serum endotoxin
histological scores of pancreas
and serum levels of inflammatory factors CRP
TNF-α and IL-1β were assessed and compared among the 3 groups.
Results
2
Compared with sham operation group
the histological score of pancreas
bacterial translocation in the blood
MLNs and pancreatic tissues
serum endotoxin level
and serum levels of CRP
TNF-α and IL-1β were all significantly higher in the SAP group and APD group (
P
<
0.05). While compared with the SAP group
the above indicators were obviously lower in the APD group (
P
<
0.05).
Conclusion
2
Early APD reduces intestinal bacterial translocation and systemic inflammatory response in rats with SAP
and thus attenuates the severity of SAP.
