Does removal of prophylactic pancreatic stents induce acute pancreatitis?

摘要

We read "with interest the recent retrospective analysis of Moffatt et al. Temporary placement of prophylactic pancreatic stents (PPSs) is an accepted approach to reduce the risk of post-ERCP pancreatitis (PEP) in high-risk cases. The idea of PPS placement to prevent PEP is supported by the stent's role in maintaining the integrity of pancreatic outflow. Different types of plastic stents have been used over the years. Complications of PPS placement including early stent dislodgment, inward stent migration, stent occlusion, stent-induced pancreatic duct injury, as well as unsuccessful placement, which can result in an even higher risk of PEP, have been already reported.
