EUS-guided drainage of peripancreatic fluid collections and necrosis by using a novel lumen-apposing stent: a large retrospective, multicenter U.S. experience (with videos)

Minimally invasive endoscopic treatment of necrotizing pancreatitis: A case report with images and review of the literature

“…In cases of WON, early stent obstruction, infection and multiple endoscopic therapies might be necessary. 5 Recently, a fully covered-self expanding metal stent with double anchoring has been developed. This type of stent has shown to be more effective and safe to perform endoscopic transmural drainage.…”

Lumen apposing metal stents: A review of current uses and outcomes

“…Adverse events occurred in 8 patients (9.8%), which included stent maldeployment (n = 2), and self-limited bleeding (n = 6). 17 In a study of 47 patients with PFCs, Chandran et al 18 demonstrated 76.6% resolution of PFCs using the NAGI LAMS. The authors attributed their decreased rate of resolution compared with the AXIOS stent as used in the study by Siddiqui et al 17 to their larger subgroup of patients with WON, infected WON, and infected pseudocysts.…”

The authors attributed their decreased rate of resolution compared with the AXIOS stent as used in the study by Siddiqui et al 17 to their larger subgroup of patients with WON, infected WON, and infected pseudocysts. Adverse events included 4 early and 6 late stent migrations, 4 cases of sepsis, and 1 clinically significant gastrointestinal (GI) bleed.…”

“…The average duration of follow-up was 13 months with only 1 recurrence at 12 months after stent removal (Table 1). [14][15][16][17][18][19][20][21] With regard to the safety of LAMS versus plastic stents, a recent ongoing randomized trial for drainage of PFCs via LAMS versus plastic stents demonstrated stent-related adverse events in 50.0% (6/12) patients who received LAMS and no adverse events in patients who received plastic stents. 22 Similar results were seen in a previous study using both LAMS and plastic stents for drainage of PFCs where stent-related adverse events occurred in 10.0% (2/20) of patients who received LAMS and 2.5% (1/40) patients who received plastic stents.…”

“…[16][17][18][19][20] There are few studies in the literature comparing plastic stents to LAMS for drainage of PFCs. However, performing a CT scan at 3 weeks post-procedure for all patients who received a LAMS followed by stent removal of evidence of PFC resolution may be reasonable as proposed by Bang et al 22 …”
