Bowel displacement and protection techniques during percutaneous renal tumor thermal ablation.

Although bowel injury is a rare complication of renal radiofrequency ablation, the potential consequences can be devastating. Therefore, it is prudent to perform bowel displacement/protection procedures when feasible. The main bowel displacement techniques include hydrodissection, gas-insufflation, balloon interposition, and electrode torquing. In this article, these techniques are discussed and the steps involved in performing these procedures are enumerated. Copyright 2010 Elsevier Inc. All rights reserved.
