Liver abscesses: successful treatment with choledochoduodenostomy

I have described two cases of hepatic abscess due to E coli after choledochoduodenostomy for choledocholithiasis, and have discussed the relationship between abscess formation and size of the anastomosis. I conclude that a small anastomosis may in some cases predispose to this problem. Treatment by percutaneous drainage of the abscess was successful in both cases.
