UMIN-CTR Clinical Trial

Unique ID issued by UMIN UMIN000026416
Receipt number R000030348
Scientific Title Advanced techniques have been developed to overcome difficult cannulation cases in endoscopic retrograde cholangiopancreatography (ERCP ). Pancreatic duct guidewire placement method (PGW) is performed in difficult cannulation cases; it is possible that it places patients at risk of post-ERCP pancreatitis (PEP). The mechanism of PEP is still unclear, but pancreatic duct pressure and injury of pancreatic duct are known causes of PEP. Therefore, we hypothesized a relationship between pancreatic duct diameter and PEP and predicted that PGW would increase the risk of PEP in patients with non-dilated pancreatic ducts. This study aimed to investigate whether PGW increased the risk of PEP in patients with pancreatic duct diameter <3 mm.

Basic objectives -Others

The mechanism of PEP is still unclear and considered to be related to various factors, including pancreatic duct pressure and damage of pancreatic duct, but no existing study focuses on the relationship between pancreatic duct diameter and PEP. We focused on pancreatic duct diameter and PGW to clarify the association between PGW and PEP; we hypothesized that when the pancreatic duct diameter is not dilated, PGW may increase the risk of PEP by further increasing the pressure in the pancreatic duct or by causing irritation or injury of the duct during ERCP. Therefore, we focused on patients with pancreatic duct diameter of less than 3 mm.
