Abstract
Objectives
Proximal migration is one of the complications after pancreatic duct stenting. This study aimed to determine the incidence of proximal migration and to analyze the rescue methods.
Materials and Methods
A search was performed in MEDLINE/Embase database. The literatures included were reviewed and analyzed. Retrieval tools were classified into the following 3 classes: class A works by indirectly contacting the outer surface of the stent. Class B works by directly contacting the outer surface. Class C works by directly contacting the inner surface.
Results
416 literatures were retrieved from 1983 to 2021. 15 literatures were included. The incidence of proximal migration of pancreatic stents was 4.7% (106/2246). The success rate of endotherapy was 86.6% (214/247), and the surgical conversion rate of it was 9.3%. Among the 214 cases in which the displaced stents were successfully removed under endoscopy, 49 cases (22.9%) used class A methods, 154 cases (72.0%) used class B methods, and 11 cases (5.1%) used class C methods. The overall rate of postoperative complication was 12.1%, including postprocedure pancreatitis (9.1%, 18/247), followed by bleeding (1.5%), perforation (1.0%), and biliary infection (0.5%).
Conclusions
Endoscopy is an effective method for the treatment of proximal displacement of pancreatic stents with acceptable complication rate.
