ABSTRACT
Objective To investigate the influence of CO_2 pneumoperitoneum on intestinal mucosa permeability in rats with liver cirrhosis.Methods Fifty rats were randomly divided into following groups: control group(n=5),cirrhosis group(n=5) and pneumoperitoneum group(n=40);the pneumoperitoneum group was further divided into 8 mm Hg group(n=20) and 13 mm Hg group(n=20).Four time points were chosen,including 0.5,2,6,and 12 hours after the end of pneumoperitoneum.After rat models with cirrhosis were established successfully,the abdominal cavity was insufflated with CO_2 and maintained under the pressures of 8 mm Hg and 13 mm Hg respectively for two hours.The portal venous blood was collected and the levels of D-lactic acid and endotoxin were measured.Results The levels of endotoxin and D-lactic acid in cirrhosis group were much higher than those of control group(P0.05).Conclusion The intestinal mucosa permeability is increased in rats with liver cirrhosis.It can be further increased under CO_2 pneumoperitoneum with certain pressure and time and in a pressure-dependent manner.The permeability can decrease after removal of pneumoperitoneum.
