About

This study intends to determine the incidence, risk factors and endoscopic treatment of proximally migrated pancreatic stents.

Full description

Endoscopic pancreatic stenting can be used to treat a variety of pancreatic disorders, including chronic pancreatitis-induced pancreatic duct stenosis, pancreatic schizophrenia, pancreatic leakage, pancreatic pseudocyst drainage, and prophylactic pancreatic duct stenting. Postoperative stent migration is one of the complications associated with pancreatic stent placement.

In this retrospective study, more than 9,000 Endoscopic retrograde cholangiopancreatography (ERCP) cases at our center over the past 25 years will be analyzed to determine the incidence, risk factors and endoscopic treatment of proximally migrated pancreatic stents.

Enrollment: 9,073 patients

Sex: All

Volunteers: No Healthy Volunteers

Inclusion criteria

• Pancreatic stent placement under ERCP;
• Pancreatic stent migration found by ERCP;
• Displaced pancreatic stent removal by ERCP technique.

Exclusion criteria

• Incomplete ERCP records (e.g., missing stent size information);
• Immediate removal of pancreatic stent following implantation for a variety of reasons.
