Endoscopic placement of the plastic stent has been adopted as an initial treatment for chronic pancreatitis with pancreatic duct stricture. Stent fracture while attempting removal is one of the complications of stent exchange. The use of the unilateral-flange stent in these patients has never been reported. We investigated the outcomes associated with the use of this stent with regard to stent exchange and stent-related adverse events. From 2011 to 2015, 9 patients with chronic pancreatitis and main pancreatic duct (MPD) stricture treated with the unilateral-flange stent were included. Eleven endoscopic treatment sessions, 53 endoscopic stent deployments or exchange procedures were analyzed. Technical success rate was 100%. Forty-eight stents were exchanged on a regular basis in 1 to 6-month intervals. Another 5 stent exchange procedures were urgently performed due to stent obstruction and caused pancreatitis (n=2), symptomatic external stent migration (n=2), and concurrent cholangitis (n=1). The rate of symptomatic migration was 3.7%. The mean duration for stent exchange was 29 minutes and no stent fracture occurred during the procedure. Of 11 endoscopic treatment sessions, 7 were successful, 3 were changed to the metallic stents, and 1 was lost to follow-up. According to this study, unilateral-flange stent placement for benign MPD stricture is technically feasible and effective. Stent removal during the exchange period is unchallenging and without stent fracture.
