Abstract

Background

In the management of mild acute biliary pancreatitis, it is generally recommended to perform laparoscopic cholecystectomy after the subsidence of the attack during the same hospital admission. The effect of laparoscopy on abdominal organs has been widely investigated but not in acute pancreatitis. This study used an animal model of mild acute pancreatitis to examine the effects of CO2 pneumoperitoneum on acute pancreatitis in rats.

Methods

Mild acute pancreatitis was induced in 30 male Sprague-Dawley rats by surgical ligation of the biliopancreatic duct. After 2 days, animals were assigned to three groups: sham operation (animals were anesthetized for 30 min without undergoing laparotomy), CO2 pneumoperitoneum (applied for 30 min at a pressure of 12 mmHg), and laparotomy (performed for 30 min, and then the abdomen was closed). Two hours after the surgical procedures, animals were killed and levels of lactate dehydrogenase, aspartate aminotransferase, glucose, urea, hematocrit, and leukocyte count among Ranson’s criteria and levels of amylase, lipase, and total bilirubin were measured to determine the severity of acute pancreatitis. Histopathologic examination of the pancreas was done, and malondialdehyde and glutathione levels of the pancreas and lung were determined.

Results

The only significant differences between the groups were in lactate dehydrogenase and aspartate aminotransferase levels, which were significantly higher in the pneumoperitoneum group compared to the sham operation group.

Conclusion

CO2 pneumoperitoneum for 30 min at a pressure of 12 mmHg did not affect the severity of acute pancreatitis induced by ligation of the biliopancreatic duct in rats.
