Abstract

Abstract : Background and Aim: Fully covered self‐expandable metal stent (FCSEMS) placement has been tried for pancreatic ductal strictures in chronic pancreatitis. However, the long‐term outcome of this procedure remains unknown. The present study aimed to investigate the procedural and long‐term outcomes of FCSEMS placement in patients with benign refractory pancreatic ductal strictures. Methods: Between August 2011 and September 2015, 18 patients underwent endoscopic treatment with FCSEMS for benign refractory pancreatic ductal stricture. Technical success, clinical success, radiological success, and adverse events were assessed. Results: Stent placement was successful in all patients (technical success rate, 100%). Reduction in pain score of >50% was achieved in 15 of the 18 patients (clinical success rate, 83.3%). In all patients, stents could easily be removed at a median of 7.5 months (interquartile range [IQR], 6–13.6) after their insertion. FCSEMS migration did not develop in any patient. Ductal stricture was improved in 15 patients (radiological success rate, 83.3%). After definite stent removal, 13 of the 15 (86.7%) patients who had responded to pancreatic stenting maintained the response during follow up (median of 47.3 months; IQR, 7.4–57.1). Conclusions: FCSEMS placement appears to be safe and effective for the treatment of benign refractory pancreatic ductal strictures as it can provide persistent improvement in the stricture in long‐term follow up.
