However, there are few dedicated devices for EUS-PD. Recently, we have developed a new plastic stent dedicated to EUS-PD and have conducted a feasibility study to evaluate its efficacy. In the current study, we evaluated the long-term efficacy of this new plastic stent.<\/jats:p><jats:p>\n          Patients and methods\u2002Thirty patients (61\u200a\u00b1\u200a14.3 years old, 14 men) with acute recurrent pancreatitis caused by a stricture in the main pancreatic duct (MPD) or stenotic pancreatoenterostomy were treated at our institution using our recently developed 7Fr plastic stent between August 2013 and April 2017.<\/jats:p><jats:p>\n          Results\u2002The stent was placed successfully in all patients (30\/30) and early clinical success was achieved in all of them. Early adverse events (AEs) occurred in seven patients (23.3\u200a%), namely, self-limited abdominal pain (n\u200a=\u200a5), mild pancreatitis (n\u200a=\u200a1), and bleeding which required transcatheter arterial embolization (n\u200a=\u200a1). Two patients died of primary disease and three were lost to follow-up.\u200aThe remaining 25 patients were followed up after initial EUS-PD for a median of 23 months (range, 6\u200a\u2013\u200a44 months). Twenty patients required regular stent exchange (3 times; range, 1\u200a\u2013\u200a12 times). Spontaneous stent dislodgement was observed in six patients. Four patients wanted their stents removed 1 year after the initial intervention. Twelve patients (48\u200a%) had regular stent exchange 1 year after the initial intervention. Three patients converted to standard transpapillary pancreatic duct stenting by conventional ERCP. Finally, nine patients (36\u200a%) had complete stent removal either intentionally or by spontaneous dislodgement without any symptoms.<\/jats:p><jats:p>\n          Conclusion\u2002The new plastic stent for EUS-PD was associated with not only short-term technical success but also long-term clinical success in the majority of patients evaluated in this
