Active clinical trials for "Pancreatitis"

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.

Obesity is a well-established risk factor for acute pancreatitis (AP). As for non-alcoholic fatty pancreas disease (NAFPD), it is evident that it is correlated with obesity. This is apparently the first study evaluating the association between NAFPD and severity of AP after taking into account several covariates.

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.

This study is an ancillary of APPRENTICE. This will be the international based study.

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.

To explore differences in patients, techniques and outcomes across the international cohort to identify areas of practice variability in the presentation and management of acute complicated calculous biliary disease.

Severe Acute Pancreatitis (SAP) is an acute inflammatory condition of the pancreas characterized by organ dysfunction and increased mortality. Increased Intra-abdominal Pressure(IAP) in SAP is a result of inflammation of pancreatic and peripancreatic tissue, aggressive fluid resuscitation and increased capillary permeability, which is associated with organ dysfunction, by limiting the vascular supply to the tissue. Abdominal Compartment Syndrome (ACS) is defined as IAP greater than 20 mm of Hg and is considered an abdominal catastrophe. Intra-abdominal Hypertension (IAH, Intra-abdominal pressure > 12mm of Hg), may contribute to early organ dysfunction, ACS and eventually hemodynamic collapse if left untreated. This signifies the need for determining the burden of the condition and identifying the high risk patient group who are prone to develop IAH /ACS and predicting mortality associated with the condition. Measurement of IAP will be done indirectly by measuring intravesicular pressure using modified kron's method. IAP will be measured at the time of admission into Intensive Care Unit (ICU) and every day thereafter during the initial five days of ICU admission. Any reading of IAP ≥12 mm of Hg shall be considered as IAH. SOFA and APACHE II score will be noted on the day of admission in the ICU. Any interventions, surgical or non surgical as per clinician's decision will be recorded. The patients will be followed up until discharge or mortality until 30 days. The proposed study aims to assess the predictive ability of IAP during the first 5 days of ICU admission for predicting mortality in patients with SAP. Prediction accuracy will also be compared with SOFA and APACHE II scores.

The study aimed to identify risk factors for post-ERCP pancreatitis(PEP) after ESWL, and the relationship between the occurrence of post-ESWL pancreatitis and PEP.

A randomized controlled trial to determine the optimal placement duration of pancreatic duct stents (PDS) inserted during ERCP: 2 vs 4 weeks

In this research project the investigators intend to find out if Endoscopic Ultrasound (EUS) criteria for diagnosing chronic pancreatitis can be correlated with pathologic characteristics of tissues taken from pancreas of patients with suspected chronic pancreatitis. This will be a retrospective study which will examine results from biopsy specimens and endoscopic ultrasound findings in suspected chronic pancreatitis.
