About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

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.

Treatment and study plan

Analysis of ERCP records

Procedure

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.

Primary outcomes

  1. Incidence of proximally migrated pancreatic stents

    Time frame: Within 1 month after data analysis

  2. Success rate of endoscopic removal of migrated pancreatic stents

    Time frame: Within 1 month after data analysis
