A new inflatable T tube for completion cholangiography.

A new inflatable T tube has been designed and used in the performance of completion cholangiography following exploration of the common bile duct. The T tube has proved to be useful in avoiding the time delays and frustrations associated with suturing, removal and resuturing of T tubes during identification and removal of common bile duct stones. Furthermore, after clearance of the common bile duct of stones, the inflatable T tube may be left in the common bile duct for the purpose of drainage and postoperative cholangiograms. Finally, the T tube is of sufficient size (14F) to allow any possible postoperative roentgenographic extraction procedures to be done.
