Direct endoscopic necrosectomy is a cumbersome and time-consuming procedure, that can be necessary in cases of infected walled-off pancreatic necrosis not responding to drainage only as a step-up approach after EUS-guided drainage OR as a primary treatment in a case of high necrotic solid content. Until now, DEN has been performed with non-dedicated devices: common polypectomy snares, caps, Dormia baskets and retrieval nets. In some cases, a mechanical lithotriptor was used for fragmentation of large necrotic fragments. In this way DEN requires multiple, long-lasting sessions to achieve adequate clearance of solid necrotic content. The multiple endoscopic sessions result in prolonged hospital stay, increased costs and have potential consequences for patients who must undergo multiple interventions under deep sedation or anesthesia. Necrolit was born from a constant research and development activity in order to develop a dedicated and specific endoscopic device for Direct Endoscopic Necrosectomy. The double lumen catheter allows two devices to coexist inside, each of them with its own reference handle. 1 A special monofilament loop with a diameter of 0.90 mm, ultra stiff ends with a rounded tip to avoid the traumaticity of it during use. The internal section of the loop has the peculiarity of being flat. This results in a greater shape memory and a superior synergistic ability to cut and grip the necrotized tissue. 2 A particular container of equivalent width and length, with nitinol filaments with variable flexibility that give perfect retrieval capacity. The container has no tip and the junction in the distal part between the filaments with variable flexibility creates a hollow. This characteristic gives it atraumaticity and adaptation to the cavities object of the recovery of the necrotized tissue. The spiral steel core that connects the handles to the retrieval system deliberately has a small diameter in order to give a rotation called "helix effect" essential to allow the necrotized tissue to detach quickly The transluminal procedure is performed by using a flexible gastroscope with a water irrigation system and CO 2  insufflation, inserted through the fistula tract or LAMS. Tissue debris is mechanically fragmented and removed alternatively using the two devices, coexisting inside the catheter, the monofilament loop cut and grip the necrotized tissue and a container retrieve the tissue. The entire procedure is performed with Necrolit , without need for accessories exchange… sparing costs and the duration of the necrosectomy procedure. Necrolit is anew device , dedicate for Direct endoscopic necrosectomy, which avoid need for accessories exchangeand is able to reduce time and number of sessions, thus improving success rate and reducing adverse events and costs!
