Papillary balloon dilation is not itself a cause of post‐endoscopic retrograde cholangiopancreatography pancreatitis; results of anterograde and retrograde papillary balloon dilation

Abstract

The rates of post-procedural pancreatitis and hyperamylasemia were significantly higher after retrograde dilation with EPBD than after antegrade dilation with PTPBD for the removal of bile duct stones. Although the mechanism of pancreatitis following papillary balloon dilation remains unclear, post-EPBD pancreatitis may be associated with procedures before and after balloon dilation similar to mechanical lithotripsy rather than balloon dilation itself.
