Aims:

Endoscopic ultrasound (EUS)-guided transluminal drainage for pancreatic pseudocyst (PP) is steadily increasing and has become the first-line treatment. Although lumen apposing metal stent (LAMS) was recently introduced and its feasibility and safety was established by several clinical trials, there was no data for clinical outcomes of PP drainage. We retrospectively reviewed patient with PP who underwent endoscopic ultrasound-guided PP drainage by using plastic stent (PS) or LAMS and compared clinical outcomes between two stents.

Methods:

Endoscopy databases were searched for all patients who had undergone EUS-guided pseudocyst drainage between January 2011 and May 2017. By reviewing medical records and radiologic findings, we compared the clinical outcomes of EUS-guided pseudocyst drainage according to type of stent.

Results:

This study enrolled 27 patients (mean age, 54 years) with PPs who underwent EUS-guided transluminal drainage including 17 that were drained by using PS and 10 by using LAMS. One case of technical failure due to failed stent insertion was occurred in PS group. There was no statistical significance of technical success between two groups (94.1% vs. 100%, p = 1.0). Among subjects of technical success and clinical success, recurrence of pseudocyst after stent removal was occurred in 4 of 12 patients with PS and 2 of 7 patients with LAMS. There was no statistical difference in recurrence rate between two groups (33.3% vs. 28.6%, p = 1.0). Univariate anal...

Conclusions:

Our study showed that LAMS was similar to PS in terms of clinical outcomes. Further prospective randomized trials are required to validate the superiority of LAMS.
