Brief Summary:
The purpose of the study was to analyze the resolution rate of benign biliary strictures due to chronic pancreatitis after temporary insertion of unflared-ends and flared-ends fully covered self-expandable metal stents.

Condition or disease Intervention/treatment Phase
Benign Biliary Strictures Chronic Pancreatitis Device: FC Nitinol SEMS (Niti-S, TaeWoong Medical Co., Korea) Not Applicable

Detailed Description:

Endoscopic treatment of benign biliary strictures include the placement of plastic stents or Self-Expandable Metal Stents. Long term results of placement of a single plastic stent are disappointing. Better results have been obtained by endoscopic insertion of multiple plastic stents.

Biliary Self-Expandable Metal Stents used for malignant strictures are uncovered or partially covered with a plastic coating. More recently, fully covered SEMS have been developed and are now available on the market and due to their removability are proposed also for benign indications.

Uncovered and partially covered biliary Self-Expandable Metal Stents for chronic pancreatitis-related benign biliary strictures on long-term may clog due to tissue ingrowth through the uncovered meshes.

Removable fully covered Self-Expandable Metal Stents seem to be an attractive option for CP-related BBS, but scarce data are available in the literature.

The investigators conducted a feasibility, prospective, tertiary single-centre trial to investigate the durable resolution of chronic pancreatitis-related benign biliary strictures after temporary insertion of FC SEMS with unflared-ends and flared-ends.
