Background/Aims: Endoscopic ultrasound (EUS)-guided transmural drainage for peripancreatic fluid collections (PFCs) has gainedwide acceptance as a nonsurgical intervention. Although a lumen-apposing metal stent (LAMS) was recently introduced, there are fewdata comparing the clinical outcomes between LAMS and plastic stent (PS) drainage. Methods: Endoscopy databases of all patients who had undergone EUS-guided drainage for PFCs were searched and the clinicaloutcomes of EUS-guided drainage according to stent-type used were compared. Results: A total of 27 patients (median age, 56 years) with PFCs underwent EUS-guided transmural drainage between January 2011 andDecember 2017. Of these, 17 underwent PS placement and 10 underwent LAMS placement. There was no significant difference in thetechnical success rate between the 2 groups (94.1% vs. 100%, p=1.0). Procedure time was shorter in the LAMS group compared to thatin the PS group (10.6±2.5 min vs. 21.4±9.5 min, p=0.002). Among subjects with clinical success, recurrence of PFC after stent removaloccurred in 5 of 12 patients with PS and 4 of 10 with LAMS, without statistical difference (41.7% vs. 40.0%, p=1.0). Conclusions: Although our study showed similar clinical outcomes for LAMS and PS, further prospective trials are required to validatethe superiority of LAMS.
