Randomized Controlled Trial Clinical TrialRandomized double-blind clinical trial of celiac plexus block for percutaneous biliary drainage.
This study was undertaken to determine the efficacy of celiac plexus block (CPB) as a method of providing analgesia for percutaneous biliary drainage (PBD). ⋯ This study indicates that CPB is not an effective means of providing additional visceral pain relief over and above that which can be accomplished with self-administered intravenous medication for patients who undergo PBD.
