ABSTRACT
Objective To investigate the place reaction of support drainage tube in cholecystojejunostomy and its pathological changes.Methods Eight pigs were randomized into 2 groups.The tube-placing cholecystojeunostomy(n=2)or choledochocholedochostomy(n=2)and non-tube-placing cholecystojejunostomy(n=2)or choledochocholedochostomy(n=2)were performed respectively.All the 8 pigs were sarcrificed 3 months after the operation for pathological examination.Results Gross anatomy catheter group showed anastomotic inflammatory hyperplasia, wall hardening hyperplasia,luminal narrow contracture and stone formation.Microscopic biopsy showed bile duct mucosa in interstitial lymphocytes, plasma cells and other chronic inflammatory cell infiltration, a large number of fibrous tissue hyperplasia.However, these features were not found in pigs without placing the tube.Conclusion The tube can not prevent the stenosis.It might promote the formation of stricture since it can stimulate inflammatory hyperplasia and tissue hardening.
