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.

Interventions

PROCEDUREAnalysis of ERCP records

Data will be extracted from ERCP records of stenting, mainly including: 1) Age at the time of ERCP; 2) Gender; 3) Indication; 4) Papilla selection (major or minor); 5) Whether endoscopic sphincterotomy (EST) was performed; 6) Presence of nipple diverticulum; 7) Morphology of the pancreatic duct; 8) Status of pancreatic duct stones; 9) Number, shape, material, diameter and length of the stent; and 10) Operation of the bile duct. Additional data were extracted from the pertinent ERCP records of stent migration: 1) Shape, material, diameter and length of the displaced stent; 2) Type of migration; and 3) Removal tools.
