Single-step placement of a self-retaining "accordion" catheter.

The "accordion" catheter was developed as an adjunct to the Hawkins needle guide to provide safe single-step percutaneous drainage. The Hawkins needle guide is a long, 22-gauge "skinny" needle-cannula system that can be used like any other skinny needle. It can also be used for drainage catheter placement. The accordion catheter is a 6.5 French Teflon catheter with a sigmoid tip. With the use of monofilament, the sigmoid tip can be retracted into a "T" configuration to prevent dislodgment. The 22-gauge needle guide, preloaded with an accordion catheter, can be manipulated safely while the drainage target is located. Then the accordion catheter can be advanced into the target over the needle guide. The "accordion" is easily formed, even in small targets. Successful drainage was achieved in 127 of 131 drainage procedures in which this technique was used. Sepsis did not occur as a complication in any of these procedures.

Vincristine-induced megacolon.

Three cases of vincristine-induced megacolon are described with radiographic correlation. Vincristine is a widely used chemotherapeutic agent with neuropathic side effects causing colonic dilatation and constipation. The radiologist should be aware of this entity to prevent unnecessary procedures and, possibly, surgery.

Button self-retaining drainage catheter.

To help improve patient acceptance of long-term internal/external catheter access to the biliary tract in those with benign biliary obstruction, a simple design allows the catheter end to remain flush with the skin. It consists of a clothes button affixed to the drainage catheter with a wood screw after the catheter has been cut off at the skin exit. This button/screw device has been used successfully in 22 patients over the last 10 years; catheter exchanges were easily accomplished.
