Pancreatic stents for the prevention of post-endoscopic retrograde cholangiopancreatography pancreatitis should be inserted up to the pancreatic body or tail

Figure 1 Subjects in this study. A total of 296 patients underwent their first ERCP procedure and had a pancreatic stent inserted at our hospital between January 2007 and November 2017. Among these patients, 147 who received ERCP primarily for biliary investigation and had a stent inserted to prevent post-ERCP pancreatitis were included in this study. We divided these patients into two groups: 131 patients with a stent inserted into the pancreatic head (head group) and 16 patients with a stent inserted up to the pancreatic body or tail (body/tail group). ERCP: Endoscopic retrograde cholangiopancreatography.
