BACKGROUND AND AIMS: In chronic pancreatitis, fully covered self-expanding metal stents (FCSEMS) are used to treat refractory pancreatic duct strictures. However, the FCSEMS design, effectiveness, safety, optimal stent indwelling time and patient selection remain unclear. This study aimed at evaluating technical success, clinical success and adverse events with FCSEMS in patients with symptomatic pancreatic duct stricture.
METHODS: The prospective study was conducted between May 2017 and May 2021 at a tertiary care center for chronic pancreatitis with refractory pancreatic duct stricture using controlled radial expansion (CRE) endoscopic retrograde cholangiopancreatography (ERCP) with FCSEMS (Niti-S, Bumpy stent, Taewoong Medical, Gimpo-Si, South Korea).
RESULTS: During the study period, a total of 11 patients underwent ERCP with FCSEMS for refractory pancreatic duct stricture. The mean age (± standard deviation, [SD]) was 32.36 ± 10.98 years and nine patients (81%) were male. Technical and clinical success rates were 100% and 90.9%, respectively. All patients had a history of prior pancreatic endotherapy. The median (inter quartile range, [IQR]) stent indwell time was seven (6-10) months. The median visual analogue scale (VAS) pain score pre and post-FCSEMS was 8 (5-8) and 1 (0-2), respectively (p-value 0.003). Median (IQR) follow-up after stent removal was 48 (40-60) months. One patient (9%) developed de novo main pancreatic duct (MPD) stricture, which was asymptomatic. None of the patients had cholangitis, pancreatitis, perforation, proximal migration or stent fracture.
CONCLUSION: The FCSEMS treatment appears to be safe, feasible and possibly an effective option for patients who have not responded to endoscopic plastic stenting.
