Acute Pancreatitis following Percutaneous Electrohydraulic Lithotripsy.

The gold-standard treatment of acute calculous cholecystitis is cholecystectomy. For patients not suitable for surgery, endoscopic or percutaneous techniques can be used for gallbladder decompression. The national percutaneous cholecystostomy rates have increased by 567% from 1994 to 2009*. Some of these patients are still not surgical candidates after the acute cholecystitis episode has resolved. Hence, it is crucial to have a management plan in place for such patients. There are several peroral endoscopic treatment options available, including ultrasound-guided transmural drainage, lithotripsy, and transpapillary stenting**. Furthermore, due to the advent of percutaneous biliary endoscopes, interventional radiology (IR) can now perform percutaneous lithotripsy and gallstone removal followed by cystic duct stenting. This method aims to internalize gallbladder drainage without the need for a long-term external cholecystostomy tube. Acute pancreatitis is a rare complication that can arise following interventions involving the biliary and cystic ducts. Acute pancreatitis can occur after retrograde ampullary manipulation during endoscopic retrograde cholangiopancreatography. However, this can sometimes happen after percutaneous antegrade interventions performed by IR. In this report, we will examine a rare complication that occurred in a patient with acute calculous cholecystitis: acute pancreatitis following percutaneous electrohydraulic lithotripsy with cystic duct stenting performed by IR.
