Pancreatitis, Stent Dislodgement
Conditions
Brief summary
The Retention of pancreatic stents for prophylaxis of post-ERCP pancreatitis (PEP) is assessed by abdominal x-ray according to international Guidelines. The current study aimed to analyze whether prophylactic pancreatic stents can be detected by transdermal ultrasound to save the x-ray examination.
Detailed description
Pancreatitis is the most common complication of endoscopic retrograde cholangiopancreatography (ERCP). Several pharmacologic and procedure-related measurements have been established for post-ERCP pancreatitis (PEP) prophylaxis one being the placement of pancreatic duct stents in patients with high risk for PEP. The beneficial role of pancreatic stenting in the prophylaxis of PEP was demonstrated in large meta-analyses. The used stents have a high potential of self dislodgment, retained stents have to be removed endoscopically after 5-10 days. For evaluation of spontaneous stent passage abdominal x-ray ist used and accordingly retained stents removed. The current study aimed to analyze whether prophylactic pancreatic stents can be detected by transdermal ultrasound to save the x-ray examination.

|---|---|---|
| Negative predictive value of the sonographic detection of pancreatic stents | 5-10 days after stent placement | Test whether and why the stents cannot be detected reliably by ultrasound |
