Needle/catheter introduced with great difficulty into a thick-walled gallbladder demonstrated a large solitary stone (arrows). Introduction of a guide wire for catheterisation failed, as the wire could not be coiled in the small area of gallbladder below the stone. n caused a large perforation in the friable gallbladder wall which required cholecystectomy 52 Percutaneous Cholecystostomy for Biliary Drainage b a Fig.
In one step, the Olbert balloon dilator produces a track to the gallbladder of 1 cm in diameter. A working sheath may be backloaded on the balloon catheter with a dilator. The balloon is deflated and the dilator is inserted over it, followed by the working sheath. Alternatively', a series of coaxial dilators are inserted into the gallbladder until the track is dilated to 18 French, and a Teflon sheath of this size is inserted into the gallbladder lumen (Fig. 1 g). During dilator insertion the dilators should always be pointed towards the patients head.

In vivo studies in dogs in whom human cholesterol gallstones were implanted surgically showed that the stones dissolved rapidly following instillation of MTBE via a surgically implanted gallbladder catheter. Histology of the gallbladder subsequently showed no evidence of gallbladder injury from the MTBE. MTBE is a flammable solvent with explosive properties.
