A Novel, Small‐Incision, Gasless Videoscope‐Assisted Necrosectomy for Infected Walled‐Off Necrosis: A Single‐Center Experience

Video S1: A novel, small-incision, gasless videoscope-assisted necrosectomy (VANE) for infected walled-off necrosis. The video begins with preoperative contrast-enhanced computed tomography (CE-CT) showing infected walled-off necrosis (WON) spreading in three directions. Following insufficient clinical improvement after initial interventions, a transabdominal VANE was performed on Day 52. Based on ultrasound marking, a 3-cm transverse incision was made, and the Ootsuki fukukyo tube was inserted after digital exploration. The surgical team employs a coordinated “four-hand” technique: the surgeon operates the videoscope and forceps, while the assistant provides a dynamic operative field by multi-directionally manipulating the Ootsuki fukukyo tube and performing atraumatic peeling of necrotic debris using the Kodama Dai-suction. This gasless approach ensures a clear, stable field of view without CO2-induced fogging, eliminates the risk of CO2 gas embolism and enables effective bulk removal of substantial necrotic debris. Postoperative CE-CT shows successful resolution of the WON. Please note: The publisher is not responsible for the content or functionality of any supporting information supplied by the authors.
