Abstract
AIM: To investigate the effect of different biliary drainage methods on intestinal barrier function in rats with obstructive jaundice.
METHODS: Sixty healthy SD rats were divided into four groups: sham-operation (SO) group, obstructive jaundice (OJ) group, internal drainage (ID) group, and external drainage (ED) group. One week after surgery, specimens from the rats of the SO and OJ groups were collected. Biliary drainage was performed using different methods in the ID and ED groups, and the specimens were harvested seven days after drainage. The levels of alanine aminotransferase (ALT), total bilirubin (TBIL), direct bilirubin (DBIL), and total bile acide (TBA) in serum, and sIgA in intestine mucus were determined and compared between different groups.
RESULTS: Serum levels of ALT, TBIL, DBIL, and TBA were significantly higher in the OJ group than in the SO, ID, and ED groups. The levels of sIgA in intestine mucus were significantly higher in the ID group than in the OJ and ED groups (0.272 ± 0.182 vs 0.160 ± 0.150, 0.191 ± 0.113, both P < 0.05).
CONCLUSION: Both ID and ED effectively relieve biliary obstruction and improve liver function. ID significantly increases intestinal mucus sIgA. The effect of ID on intestinal barrier function is better than that of ED.
