Background: Endoscopic ultrasound (EUS)-guided drainage of pancreatic fluid collections (PFCs) by cautery-enhanced lumen-apposing metal stents (LAMS) has largely been limited to collections located < 10 mm from the luminal wall. We present outcomes of the use of a novel 15-mm-long cautery-enhanced LAMS for drainage of PFCs located ≥ 10 mm away.Methods: This international, multicenter study analyzed all adults with PFCs located ≥ 10 mm from the luminal wall who were treated by EUS-guided drainage using the 15-mm-long cautery-enhanced LAMS. The primary outcome was technical success. Secondary outcomes included clinical success (decrease in PFC size by ≥ 50 % at 30 days and resolution of clinical symptoms without surgical intervention), complications, and recurrence.Results: 35 patients (median age 57 years; interquartile range [IQR] 47-64 years; 49 % male) underwent novel LAMS placement for drainage of PFCs (26 walled-off necrosis, 9 pseudocysts), measuring 85 mm (IQR 64-117) maximal diameter and located 11.8 mm (IQR 10-12.3; range 10-14) from the gastric/duodenal wall. Technical and clinical success were high (both 97 %), with recurrence in one patient (3 %) at a median follow-up of 123 days (58-236). Three complications occurred (9 %; one mild, two moderate).Conclusions: The 15-mm-long cautery-enhanced LAMS was feasible and safe for drainage of PFCs located 10-14 mm from the luminal wall.
