Background: To determine whether endoscopic papillary balloon dilation decreases the risk of hemorrhage without increasing the risk of acute pancreatitis, the results of endoscopic papillary balloon dilation were compared with those of endoscopic biliary sphincterotomy in patients with cirrhosis and coagulopathy.
Methods: Twenty-one patients with liver cirrhosis with coagulopathy had endoscopic papillary balloon dilation for choledocholithiasis from January 2001 to September 2003. Twenty patients with cirrhosis and coagulopathy who underwent endoscopic biliary sphincterotomy from January 1998 to December 2000, served as a historical control group.
Results: The rate of endoscopic biliary sphincterotomy related hemorrhage was 30% (6/20), whereas the rate for endoscopic papillary balloon dilation related hemorrhage was 0% (p=0.009). With regard to rates of hemorrhage in relation to Child-Pugh class, most (n=5) of the bleeding complications occurred in patients with Child-Pugh class C cirrhosis; bleeding occurred in only one patient with Child-Pugh B cirrhosis. There was no significant difference between the endoscopic biliary sphincterotomy and the endoscopic papillary balloon dilation groups for procedure-related pancreatitis (10% vs. 4.7%, respectively; p>0.05).
Conclusions: Endoscopic papillary balloon dilation may significantly reduce the risk of bleeding compared with endoscopic biliary sphincterotomy in patients with advanced cirrhosis and coagulopathy. In these patients, the substitution of endoscopic papillary balloon dilation for endoscopic biliary sphincterotomy is recommended for treatment of choledocholithiasis.
