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.
