Active clinical trials for "Pancreatitis, Acute Necrotizing"

Severe acute pancreatitis is a common reason for intensive care unit (ICU) admission and is associated with prolonged hospital stays and high morbidity and mortality rates. The Atlanta classification differentiates mild, moderate, and severe acute pancreatitis, and each of these categories correlates with morbidity and mortality. Mortality remains high, between 10% and 39%, in severe and moderately severe acute pancreatitis. After the first week, about 30% of patients with necrotizing pancreatitis develop infected pancreatic necrosis (IPN). IPN is a risk factor for mortality.The treatment of IPN combines antibiotics with interventions to remove the infected intra-abdominal material, preferably using minimally invasive techniques such as percutaneous and endoscopic drainage, which have been proven beneficial. In several studies biological markers such as procalcitonin and interleukin 8 were effective in predicting IPN. However, few clinical risk factors for IPN have been reported. Identifying risk factors may help to improve standardized strategies for early diagnosis and treatment, and then patients outcome. Our primary objective was to identify risk factors for IPN in patients admitted to the ICU for acute pancreatitis. Our secondary objective was to describe the management and outcomes of IPN

The objective of this study is to evaluate the use of the ABTHERA ADVANCE for patients requiring open abdomen due to necrotizing pancreatitis. The institutions traditional approach is to use the ABTHERA Open Abdomen dressing with Wittmann patch. However, the ABTHERA ADVANCE has shown in vitro to have improved tension on the abdominal wall that may obviate the need for costly Wittmann patch placement.

Since the majority of patients with necrotizing pancreatitis will experience a leak from the pancreatic duct during their course of disease resulting in intra- and peripancreatic fluid collections, it is reasonable to hypothesize that placement of a ductal stent may prevent some of the late complications and morbidity associated with pancreatic necrosis. This prospective, randomized, controlled multicenter trial investigates the role of early prophylactic ductal stenting in acute necrotizing pancreatitis. The purpose of the study is to determinate the safety and feasibility of early prophylactic pancreatic duct stenting in necrotizing pancreatitis in reducing complications, length of stay in hospital and in in-tensive care unit compared to the traditional treatment.

Necrotizing pancreatitis is a severe form of inflammation of the pancreas with subsequent destruction of the pancreas (necrosis). Often, this condition manifests in patients as an overwhelming systemic inflammatory response and multisystem organ failure. Many times the pancreas can become superinfected with bacteria and other organisms as a result of this process. Clinicians may decide to sample fluid from the pancreas or pancreatic tissue to determine the presence of infection. This can be done through surgery with a concurrent debridement and drainage of the pancreas or by a radiologist using an ultrasound or CT guided method to sample the pancreatic fluid. These samples are then sent for culture in the microbiology laboratory. Culture results often reveal 1-2 types of infecting bacteria that originate from the gastrointestinal tract. The investigators hypothesize that in actuality, many different kinds of bacteria may infect the pancreas. This project uses molecular DNA techniques to help identify bacteria present in the pancreas of patients with severe necrotizing pancreatitis.

Acute pancreatitis is an inflammatory process which causes a local and systemic inflammatory response syndrome (SIRS). Although the majority of patients have a mild disease course, around 20% will develop moderate or severe pancreatitis, with necrosis of the (peri) pancreatic tissue and/or multiple-organ failure. Previous studies have correlated colonic involvement as a prognostic marker in acute pancreatitis. It is well known that translocation of the colonic flora may significantly influence the clinical course of patients with acute pancreatitis. The correlation between collection(s) around colon in CT finding and clinical outcomes has not been studied in necrotizing pancreatitis. In current study, the investigators will do a prospective observational study correlating collection(s) around the colon and clinical course of patients in acute necrotizing pancreatitis.

Acute necrotizing pancreatitis is a frequent and potentially lethal disease, especially in case of infected pancreatic necrosis (IPN). IPN usually occurs after the first week of evolution. The step up approach is now widely recommended for the management of IPN. In fact, in case of suspicion of IPN, a drainage percutaneous or transgastric is recommended at first, supported by probabilist antibiotherapy. 1/3 of patients won't require any other interventions. For 2/3 of patients, an additional necrosectomy is necessary. Necrosectomy was formally realized by open laparotomy. Since de last decade, mini-invasive technics have emerged: transgastric necrosectomy, video-assist retroperitoneal debridement. laparoscopy and permitted a decreased of morbidity and mortality. Recently, Hollemans et al. developed a nomogram based on 4 variables (sex, multi-organ failure, % of necrosis and collections heterogeneity) which are negative predictors for success of catheter drainage in IPN with an receiver operating characteristic (ROC) curve at 0.76. The aim of this study is to validate on a large retrospective cohort Hollemans nomogram in predicting catheter drainage success. Secondary aims are to evaluate possible others predictors for success of catheter drainage in IPN and to evaluate the impact of antibiotherapy on microbiological results and on the need for an additional necrosectomy regarding its type and duration, as well as the emergence of multiresistance organism.

Severe acute pancreatitis (SAP) is the most severe form of acute pancreatitis (AP) and Infection of pancreatic necrosis (IPN) have shown to be one of the decisive factors defining the severity of illness. Minimally invasive techniques including endoscopy, laparoscopy, retroperitoneal approaches, etc., have recently been widely used for debridement because the procedure can further reduces surgical stress and performed not require general anesthesia, thereby reducing complications. Studies have shown that endoscopic transgastric necrosectomy can significantly reduced the proinflammatory response, complications, and hospital stay. Despite these advantages, there are some limitations with this approach. First, transgastric necrosectomy should be performed as late (about 4 weeks) in the course of the disease as possible to allow necrosis to wrap, since early debridement may result in a higher patient fatality rate. However, patients with SAP are often in a severely ill state due to sepsis or MODS at an early stage, which causes them unable to adhere to necrotic tissue encapsulation by conservative treatment. Second, the ideal patient to select for this approach has necrosis confined in the vicinity of gastroduodenal location. Last, up to 27% of IPN patients require additional percutaneous catheter drainage (PCD) after undergoing endoscopic transluminal therapy. This may be explained by the fact that dissemination of necrosis, digestive enzymes and inflammatory mediators from the necrotic tissue lumen to other parts of the abdominal cavity during endoscopic procedures. Percutaneous catheter drainage (PCD) has always been the principal treatment measure for patients with AP at early stage (< 4 weeks) or those with collections or necrosis extending into deeper anatomical planes. Irrigation through peripancreatic drainage placed after open laparotomy has been the standard treatment for patients with AP who had undergone surgical necrosectomy. However, this proactive approach has not been widely used in the setting of PCD. To adequate drainage and removal of necrosis, an early percutaneous continuous irrigation assisted vacuum drainage in combination with subsequent endoscopic transgastric necrosectomy which has not been reported so far was applied in critically ill patients with SAP.

Try to collect about 350 cases of acute necrotizing pancreatitis at the First Affiliated Hospital with Nanjing Medical University and Nanjing General Hospital of Nanjing Military Command. Then the investigators studied the incidence and the risk factors of ARDS in patients with acute necrotizing pancreatitis.

Cytokines such as such as TNF-a, IL-1, IL-6 correlate with the severity of pancreatitis.Neuroendocrine pathways, such as the sympathetic nervous system or parasympathetic nervous system, in turn, have some impact on the immune systems, through a-2 adrenoreceptor stimulation or the cholinergic anti-inflammatory pathway. The investigators aim to use Dexmedetomidine Hydrochloride to decrease the activity of sympathetic nervous system, thus relieve inflammation response.

This is a retrospective chart review study examining 1) demographic data such as age, sex, etiology of pancreatitis 2) clinical data including radiological characteristics of walled off pancreatic necrosis, walled off necrosis related admissions and readmission following endoscopic drainage, surgical or percutaneous procedures performed for the management of walled off pancreatic necrosis, and clinical outcomes following treatment of WON (including hospital readmissions, WON resolution, procedure complications, WON related death) 3) endoscopy data including indication for initial endoscopic drainage and subsequent endoscopic procedures performed for management of walled off necrosis (including additional EGD's, endoscopic drainage procedures, and/or necrosectomy)
