“…Many endosonographers prefer a modified single-step approach using a 19-G needle puncture and guidewire placement before advancement of the electrocautery delivery system. This method can also avoid tract dilation and additional over-the-wire exchanges of accessories resulting in simple procedure and reduced procedure time [13]. Endosonographers can confirm appropriate location to prevent stent maldeployment before stent insertion over the guidewire and can also acquire cystic fluids for diagnostic testing such as culture or fluid analysis.…”

“…Moreover, short FCSEMS with peculiar anti-migratory shape have been commercialized for similar indications: NAGI (Taewoong Medical); Aixstent (Leufen Medical); Hanarostent (M.I. Tech)[38] (Figure 1). LAMS have been originally designed for EUS-guided PFC drainage, as they provided large calibre to drain solid components of walled-off necrosis, low risk of leak alongside the stent and of migration, allowing trans-stent interventional procedures, such as endoscopic necrosectomy[34,39-42].…”

In the last years, endoscopic ultrasonography (EUS) has evolved from a purely diagnostic technique to a more and more complex interventional procedure, with the possibility to perform several type of therapeutic interventions. Among these, EUS-guided biliary drainage (BD) is gaining popularity as a therapeutic approach after failed endoscopic retrograde cholangiopancreatography in distal malignant biliary obstruction (MBO), due to the avoidance of external drainage, a lower rate of adverse events and re-interventions, and lower costs compared to percutaneous trans-hepatic BD. Initially, devices created for luminal procedures ( e.g ., luminal biliary stents) have been adapted to the new trans-luminal EUS-guided interventions, with predictable shortcomings in technical success, outcome and adverse events. More recently, new metal stents specifically designed for transluminal drainage, namely lumen-apposing metal stents (LAMS), have been made available for EUS-guided procedures. An electrocautery enhanced delivery system (EC-LAMS), which allows direct access of the delivery system to the target lumen, has subsequently simplified the classic multi-step procedure of EUS-guided drainages. EUS-BD using LAMS and EC-LAMS has been demonstrated effective and safe, and currently seems one of the most performing techniques for EUS-BD. In this Review, we summarize the evolution of the EUS-BD in distal MBO, focusing on the novelty of LAMS and analyzing the unresolved questions about the possible role of EUS as the first therapeutic option to achieve BD in this setting of patients.

“…UEG suggests they may be favorable if a cyst’s contents are suspected to be thicker than the thin pancreatic juice of a classic PPC, like in walled-off necrosis [23]. LAMS offer a greater lumen that in the further course may be passed with a gastroscope to mobilize the cyst’s contents if necessary [121]. In contrast, a study on pancreatic necrosectomy using LAMS and a meta-analysis on PPC drainage with SEMS found higher costs but no clear advantage over plastic stent use [122, 123], while a recently published multicenter study found superiority of LAMS over plastic stenting concerning clinical success, complication rates, and procedure duration in PPC treatment [124].…”
