Endoscopic ultrasonography-guided transgastric drainage of pancreatic fluid collections with a novel lumen-apposing metal stent / 中华消化内镜杂志

ABSTRACT

Objective@#To evaluate the efficacy and safety of a novel lumen-apposing metal stent(LAMS) in endoscopic ultrasonography(EUS)-guided transgastric drainage of pancreatic fluid collections(PFC).@*Methods@#A retrospective study of 46 patients was performed who underwent EUS-guided transgastric drainage of PFC with placement of LAMS from September 2015 to April 2017. Clinical data were reviewed and follow-up data were obtained by telephone and outpatient contact.@*Results@#A total of 49 LAMS were placed in 46 patients (2 LAMS were placed in 3 patient respectively for multiport access). The operation success rate was 95.9%(47/49), complications occurred in 14 patients(31.8%), including 2 severe complications (delayed hemorrhage and peritonitis). Additional intervention was performed in 10 patients(22.7%). The mean hospital stay was 6 days (1-40 days) and patients were followed for a mean time of 18.4 months (9-28 months). Treatment success was achieved in 40 patients(90.9%). Stent removal was performed after a mean time of 59.4 days (20-142 days), and recurrence rate was 10%(4/40) during the follow-up period.@*Conclusion@#Drainage of PFC using LAMS with special design is effective and relatively safe.
