BACKGROUND AND STUDY AIMS: Recently, a new electrocautery lumen-apposing metal stent (EC-LAMS) has been launched. The primary aim of our study was to assess the feasibility of the freehand placement, with intra-channel release, of the new EC-LAMS. The secondary aims were to assess technical and clinical outcomes and rates of adverse events. PATIENTS AND METHODS: We retrospectively evaluated 5 patients (3F; mean age: 75.6 ± 14.6 ys) who underwent new EC-LAMS placement for different indication (cholecystitis, malignant biliary obstruction and malignant gastric outlet obstruction). We described all the procedures of EC-LAMS placement, providing also an video of one of them (online supplementary material). RESULTS: Technical and clinical success was achieved in all patients who underwent new EC-LAMS placement, and no AEs were experienced. All of the EC-LAMS were placed using freehand technique with intra-channel release. CONCLUSIONS: Our initial experience with the new EC-LAMS showed a good performance of this device for different indications, especially if the stents are placed freehand and with intra-channel release. Further studies are needed to confirm our preliminary data and first impression about this new EC-LAMS.
