Obstruction of the pancreatic duct is a common feature of chronic pancreatitis and often requires interventional therapy.
Dr Andreas Weber and colleagues investigated clinical success in 19 patients after initial endoscopic retrograde pancreaticography.
The research team evaluated relapse rates during a 2-year follow-up period.

The team treated 17 of 19 patients with chronic pancreatitis by sphincterotomy and stent insertion.
The researchers found that endoscopic retrograde pancreaticography failed in 2 patients.
The team cannulated and dilated strictures, and removed stones with a dormia basket in 13 of 17 patients.
Extracorporeal shock wave lithotripsy was necessary in 5 patients.
The research team placed polyethylene stents into the dilated pancreatic duct.
Mean duration of internal pancreatic stenting was 6 months.
The researchers observed that 3 of 17 patients had recurrence of pain during the first follow-up year after stent extraction.
The team noted that in the second follow-up year, another 2 patients had a relapse.
Overall, patients' assessment of the stent therapy revealed complete satisfaction in 17 of 19 patients.
Dr Weber‘s team concluded, “Endoscopic stent therapy is a safe, minimally invasive, and effective procedure in patients experiencing pain attacks during chronic pancreatitis associated with dilated pancreatic duct.”
“According to our results, a relapse rate of approximately 30% can be expected within 2 years after stent extraction.”
“These patients may be treated by repeated stent therapy.”
