Change of bacteria and enzymes in the drainage fluid in patients with intestinal fistulas

Abstract

Objective To investigate the amount of bacteria and the expression of amylase and lipases in the drainage fluid in patients with intestinal fistulas with time courses.Methods The samples were collected from 16 patients with high intestinal fistulas from July 1998 to January 2008.The amounts of bacteria from the drainage fluid were measured 0,2 and 4 hours after taking out from the patients.At the respective time points,the intestinal juices were also collected to measure the amylase and lipase expressions.After reinfusion of succus entericus,thelevels of albumin,prealbumin,transferring,and fibronectin were measured at 0,7,and 14 days,Results There was no significant increase of bacteria in the drainage fluid within 4 hours ( F(0,2) =18 812.50,P ＞ 0.05 ; F(0,4) =387 625.00,P ＞ 0.05).and there was no change in the expressions of amylase ( F(0,2) =190.60,P ＞ 0.05 ;F(0,4) =631.75,P＞0.05) and lipase within 4 hours (F(0,2) =204.10,P＞0.05; F(0,4) =1080.05,P＞0.05).After succus entericus reinfusion,the fibronectin (F(0,14) =74.24,P ＜ 0.01 ; F(7,14) =59.78,P ＜0.01),transferring (F(0,14) =0.46,P ＜ 0.01 ; F(7,14) =0.39,P ＜ 0.05 ),and prealbumin ( F(0,14) =54.37,P ＜ 0.05) were increased significantly.Conclusions Bacteria and enzymes do not increase in the drainage fluid within 4 hours in patients with intestinal fistulas.Therefore,it is safe and effective to reinfuse succus entericus.
