Evolution of Mirizzi syndrome with biliobiliary fistula.
The mechanisms of fistula formation were analyzed in eight patients with Mirizzi syndrome with biliobiliary fistula. The fistula was type 1 in three patients and type 2 in five, according to the Corlette-Bismuth classification. The apparent mechanisms of fistula formation include inflammation of the gallbladder, its subsequent fusion to the bile duct, and increase in the internal pressure due to either contraction of the gallbladder or multiple stones. However, no predisposing conditions other than a longstanding history of cholelithiasis have been suggested. Differences in the type of fistula are considered to be due to the mode of fusion of the gallbladder to the bile duct, and the size of the perforation, which is apparently determined by the area in contact with the stone.
