Active clinical trials for "Pancreatitis, Acute Necrotizing"

Around 20 per cent of patients with acute pancreatitis develop pancreatic or peripancreatic necrosis with or without peripancreatic collection. Percutaneous catheter drainage successfully drains the liquefied component of pancreatic necrosis while the solid component still remains undrained. This infected solid component of pancreatic necrosis is probably responsible for failure of percutaneous catheter drainage which demands surgical debridement. Streptokinase is a protein secreted by several species of streptococci which can bind and activate human plasminogen. In the present study investigators plan to instill streptokinase locally in to the collections of patients with severe acute pancreatitis via pigtail catheter inorder to liquefy the solid necrotic component and analyze whether it hastens the drainage and thereby delays or obviates the need for necrosectomy.

Severe acute pancreatitis (AP) is a pathology with high morbidity and mortality. Portosplenomesenteric vein thrombosis is a well-known local complication of AP with a variable incidence, which can reach up to 50% in case of severe AP. However, there is no specific recommendation regarding the management of Portosplenomesenteric vein thrombosis. By analogy to all venous thrombosis, the European Society of Gastroenterology recommends curative anticoagulation. However, the efficacy of curative anticoagulation has never been evaluated by prospective studies. In addition, bleeding complications during AP occur in approximately 10% of patients and are associated with a poor prognosis. The investigators wish to conduct an observational multi-center study with epidemiologic aims, including all patients admitted for AP and with a diagnosis of portosplenomesenteric vein thrombosis. The aim of this study is to evaluate the therapeutic management of these patients, the efficacy and safety of anticoagulant treatment for the treatment of Portosplenomesenteric vein thrombosis, and their outcomes.

This trial is to compare clinical outcomes between patients undergoing immediate endoscopic necrosectomy compared to step-up endoscopic interventions in patients undergoing endoscopic therapy for infected necrotizing pancreatitis.

While the majority of patients with acute pancreatitis suffer a mild and uncomplicated course of disease, up to 20% develop a more severe course with development of pancreatic and/or peripancreatic necroses. With time, these necroses become encapsulated with a well-defined inflammatory wall, so called walled-off necroses (WON). Up to 30% of WONs become infected, which prolongs the length of hospital stay, increases morbidity and mortality significantly, and generally requires an invasive intervention. During the last decade, minimally invasive therapies consisting of percutaneous and endoscopic, transluminal drainage followed, if necessary, by percutaneous or endoscopic necrosectomy, have replaced open surgery as the standard treatment resulting in better patient outcomes. The investigators have for nearly two decades been practicing an endoscopic step-up approach as standard treatment for infected WON. Recently, lumen apposing metal stents (LAMS) have been introduced for the treatment of pancreatic fluid collections. The stent is fully-covered and shaped with two bilateral anchor flanges with a saddle in between. A dedicated through-the-scope delivery system, where the tip serves as an electro cautery device enables extra-luminal access and deployment of the stent. Initial results from primarily retrospective case series were promising. However, a recent randomized controlled trial failed to demonstrate superiority in terms of number of necrosectomies needed, treatment success, clinical adverse events, readmissions, length of hospital stay (LOS), and overall treatment costs. Furthermore, a number of serious adverse events with development of pseudoaneurisms probably due to collapse of the cavity have led to alterations in treatment with sequential computed tomography (CT) scans and insertion of double pigtail stents within the metal stent. In that trial, the mean diameter of the treated necroses was limited and in addition, the study was launched before the introduction of a novel 20 mm in diameter LAMS. The investigators hypothesize, that use of a 20 mm LAMS in large caliber WON is superior to the standard double pigtail technique. Aim To compare the use of a novel 20 mm lumen apposing metal stent (LAMS) (Hot Axios, Boston Scientific) with a conventional double pigtail technique for endoscopic transluminal drainage of large (> 15 cm) pancreatic and/or peripancreatic walled-of necrosis (WON).

With the development of endoscopic technology, ERCP has been widely used in the diagnosis and treatment of pancreatobiliary diseases, and has become the first treatment for most of the biliary and pancreatic diseases. Postoperative ERCP pancreatitis (PEP) is the most common and serious complication after ERCP. The purpose of this study was to explore methods for preventing postoperative pancreatitis. Participants: Patients with high-risk factors associated with PEP were included in the no-obvious patients who underwent therapeutic ERCP in our hospital from June 2018 to December 2019. Research methods: Patients were randomly divided into indometacin suppositories, indomethacin suppositories and pancreatic stents. Statistical methods: SPSS 13.0 statistical software was used. The measurement data was expressed as x± s, and t-test or non-parametric test was used. Chi-square test was used for count data.

The research design is a randomized prospective clinical study comparing the incidence of Walled Off Necrosis (WON) in patients with acute necrotizing pancreatitis.

A prospective randomized cohort study to compare whether the placement of a double-pigtail plastic stent (DPS) within a lumen-apposing metal stent (LAMS) may improve the efficacy and safety of endoscopic ultrasound guided transmural drainage of walled-off pancreatic necrosis (WON) and thus prevent potential adverse events related to LAMS insertion.

The VARD (Videoendoscopic Assisted Retroperitoneal Drainage) approach as treatment for necrotizing pancreatitis proposes an alternative to standard complicated open abdomen treatment methods. This treatment involves making a small incision and looking inside the abdomen with a videoendoscope. A videoendoscope is an instrument with a small camera and light on the end. It also has an extension tool that the surgeon can use to clean out any dead and infected tissue in the abdomen. This approach may reveal a treatment opportunity with faster recovery potential and shorter hospitalizations for patients with necrotizing pancreatitis.
