N2 - Background: Direct endoscopic necrosectomy (DEN) for treatment of walled-off pancreatic necrosis (WOPN) has been performed as an alternative to operative or percutaneous therapy. Objective: To report the largest combined experience of DEN performed for WOPN. Design: Retrospective chart review. Setting: Six U.S. tertiary medical centers. Patients A total of 104 patients with a history of acute pancreatitis and symptomatic WOPN since 2003. Interventions: DEN for WOPN. Main Outcome Measurements: Resolution or near-resolution of WOPN without the need for surgical or percutaneous intervention and procedural complications. Results Successful resolution was achieved in 95 of 104 patients (91%). Of the patients in whom it failed, 5 died during follow-up before resolution, 2 underwent operative drainage for persistent WOPN, 1 required surgery for massive bleeding on fistula tract dilation, and 1 died periprocedurally. The mean time to resolution from the initial DEN was 4.1 months. The first dbridement was performed a mean of 63 days after the initial onset of acute pancreatitis. In 73%, the entry was transgastric with median tract dilation diameter of 18 mm. The median number of procedures was 3 with 2 dbridements. Complications occurred in approximately 14% and included 5 retrogastric perforations/pneumoperitoneum, which were managed nonoperatively. Univariate analysis identified a body mass index >32 as a risk factor for failed DEN. Limitation:s Retrospective, highly specialized centers. Conclusions: This large, multicenter series demonstrates that transmural, minimally invasive endoscopic dbridement of WOPN performed in the United States is an efficacious and reproducible technique with an acceptable safety profile.
