Abstract
Objective To compare the efficiency of plastic and metal stents for symptomatic pancreatic pseudocyst (PP) drainage and analyze other main associated factors that affect the outcome of drainage therapy. Method Rates of technical and clinical success, procedure-related side effects (hemorrhage, stent migration, and cyst rupture), reinterventions, and duration of hospital stay. Results There were 52 patients, 40 patients underwent plastic stent placement and 12 patients underwent lumen-apposing metal stent (LAMS) placement. The total rate of technical success was 100%. The total rate of clinical success was 100%. The total rate of adverse events was 7.7% (4/52). On multiple logistic regression analysis, the use of plastic stents (P < 0.05, Exp B = 12.168) and the presence of a large cyst (P < 0.05, Exp B = 1.036) were shown to significantly increase the risk of reintervention. On multivariate linear regression analysis, etiology of pseudocyst (P < 0.05, B = -8.427, -9.785, -5.514) was associated with prolonged hospital stent, while stent type was not shown be a factor (P > 0.05). Conclusion Both plastic and LAMSs are proven to be highly efficient in PP drainage. The LAMS is superior in preventing complications such as migration and cyst leakage and reducing the rate of reintervention.

Abstract
In recent years, the management of symptoms of pancreatic fluid collections has shifted from surgical and percutaneous interventions to endoscopic techniques. Available data show that endoscopic drainage can be achieved with minimal morbidity and procedural-related mortality, a high degree of technical and clinical success, and acceptable risk of adverse events. Although endoscopic management of walled-off necrosis provides a durable, minimally invasive treatment option, it is still generally performed only in tertiary care medical centers because of the overall complexity of this clinical scenario.

Abstract
Walled-off necrosis (WON) is a new term for encapsulated necrotic tissue after severe acute pancreatitis. Various terminologies such as pseudocyst, necroma, pancreatic abscess, and infected necrosis were previously used in the literature, resulting in confusion. The current and past terminologies must be reconciled to meaningfully interpret past data. Recently, endoscopic necrosectomy was introduced as a treatment option and is now preferred over surgical necrosectomy when the expertise is available. However, high-quality evidence is still lacking, and there is no standard management strategy for WON. The consensus meeting aimed to clarify the diagnostic criteria for WON and the role of endoscopic interventions in its management. In the Consensus Conference, 27 experts from eight Asian countries took an active role and examined key clinical aspects of WON diagnosis and endoscopic management. Statements were crafted based on literature review and expert opinion, employing the modified Delphi method. All statements were substantiated by the level of evidence and the strength of the recommendation. We created 27 consensus statements for WON diagnosis and management, including details of endoscopic procedures. When there was not enough solid evidence to support the statements, this was clearly acknowledged to facilitate future research. Proposed management strategies were formulated and are illustrated using flow charts. These recommendations, which are based on the best current scientific evidence and expert opinion, will be useful for guiding endoscopic management of WON. Part 2 of this statement focused on the endoscopic management of WON.

Abstract
This Position Paper contains clinically oriented guidelines by the Italian Association for the Study of the Pancreas (AISP) for the diagnosis and treatment of severe acute pancreatitis. The statements were formulated by three working groups of experts who searched and analysed the most recent literature; a consensus process was then performed using a modified Delphi procedure. The statements provide recommendations on the most appropriate definition of the complications of severe acute pancreatitis, the diagnostic approach and the timing of conservative as well as interventional endoscopic, radiological and surgical treatments.

Abstract
A pancreatic pseudocyst (PPC) is typically a complication of acute and chronic pancreatitis, trauma or pancreatic duct obstruction. The diagnosis of PPC can be made if an acute fluid collection persists for 4 to 6 wk and is enveloped by a distinct wall. Most PPCs regress spontaneously and require no treatment, whereas some may persist and progress until complications occur. The decision whether to treat a patient who has a PPC, as well as when and with what treatment modalities, is a difficult one. PPCs can be treated with a variety of methods: percutaneous catheter drainage (PCD), endoscopic transpapillary or transmural drainage, laparoscopic surgery, or open pseudocystoenterostomy. The recent trend in the management of symptomatic PPC has moved toward less invasive approaches such as endoscopic- and image-guided PCD. The endoscopic approach is suitable because most PPCs lie adjacent to the stomach. The major advantage of the endoscopic approach is that it creates a permanent pseudocysto-gastric track with no spillage of pancreatic enzymes. However, given the drainage problems, the monitoring, catheter manipulation and the analysis of cystic content are very difficult or impossible to perform endoscopically, unlike in the PCD approach. Several conditions must be met to achieve the complete obliteration of the cyst cavity. Pancreatic duct anatomy is an important factor in the prognosis of the treatment outcome, and the recovery of disrupted pancreatic ducts is the main prognostic factor for successful treatment of PPC, regardless of the treatment method used. In this article, we review and evaluate the minimally invasive approaches in the management of PPCs.

Abstract
Over the last several years, there have been refinements in the understanding and nomenclature regarding the natural history of acute pancreatitis. Patients with acute pancreatitis frequently develop acute pancreatic collections that, over time, may evolve into pancreatic pseudocysts or walled-off necrosis. Endoscopic management of these local complications of acute pancreatitis continues to evolve. Treatment strategies range from simple drainage of liquefied contents to repeated direct endoscopic necrosectomy of a complex necrotic collection. In patients with chronic pancreatitis, pancreatic pseudocysts may arise as a consequence of pancreatic ductal obstruction that then leads to pancreatic ductal disruption. In this review, we focus on the indications, techniques and outcomes for endoscopic therapy of pancreatic pseudocysts and walled-off necrosis.
