Incidence, Risk Factors and Endoscopic Retrieval of Proximally Migrated Pancreatic Stents

Completed

• Conditions: Pancreatic Stent Displacement; Pancreatic Stenting
• Interventions: Procedure: Analysis of ERCP records

• Registration Number: NCT05431517
• Lead Sponsor: Changhai Hospital

Brief Summary

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

Detailed 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.
