Conditions

To evaluate the usefulness of non-flared short fully covered self-expandable metallic stent (FCSEMS) that was designed to minimize ductal injury and migration for refractory pancreatic stricture in advanced chronic pancreatitis

Interventions

Endoscopic stenting for pancreatic duct stricture using BONASTENT M-Intraductal stent

Eligibility

Sex/Gender

All

Inclusion criteria

Inclusion criteria: 1) Symptomatic benign pancreatic duct strictures 2) Initially treated with pancreatic sphincterotomy and 1-2 plastic stent (PS) insertion 3) Recurrent painful stricture after initial stricture resolution or persistent stricture despite PS(s)

Exclusion criteria

Exclusion criteria: 1) Evidence of pancreatic neoplasia on CT scan and/or EUS 2) Multiple pancreatic ductal strictures 3) Proximal pancreatic ductal strictures

Design outcomes

Primary

Measure	Time frame
Resolution of stricture : complete runoff of contrast material was observed and an inflated extraction balloon could be passed through the pancreatic duct without resistance.	—
