Guidewire Impaction in the Main Pancreatic Duct in a Patient with Chronic Pancreatitis: A Case Report.

The guidewire is an essential accessory in ERCP. Although rare, guidewires can cause complications, such as subcapsular hepatic hematoma, perforation, knotting, fracture, and impaction, during ERCP. This report describes a guidewire impaction during the endoscopic treatment of a patient with symptomatic chronic pancreatitis. The methods used to treat guidewire impaction are not well known. In the present case, the impacted guidewire was retrieved by inserting another guidewire and dilating the space adjacent to it. Endoscopists should check for the free movement of the guidewire before stent deployment. Additionally, it is important to ask for help from experienced senior staff to overcome any challenges during the procedure. In conclusion, endoscopists should be aware of the possibility of a guidewire impaction during ERCP.
