Active clinical trials for "Pancreatitis"

Oral losartan given in the dose of 50 mg one hour before ERCP was studied in the prevention of post ERCP pancreatitis in 50 patients indicated for ERCP in comparison with another 50 patients underwent ERCP without receiving oral losartan.

This study evaluates corticosteroids in the treatment of obstructive jaundice in autoimmune pancreatitis and/or immunoglobulin G4 (IgG4)-related sclerosing cholangitis in adults. Half of participants will receive corticosteroids alone, while the other half will receive corticosteroids with biliary stent at the beginning.

To determine if the timing of administration of indomethacin affects the primary outcome of post-ERCP pancreatitis (PEP). Patients undergoing ERCP will be randomly assigned to receive pre or post-procedure rectal indomethacin to prevent the occurrence of PEP.

Timing of laparoscopic cholecystectomy following after endoscopic retrograde cholangiography for acute biliary pancreatitis is a controversial issue. There are still many confounding findings offering either early laparoscopic cholecystectomy within 72 hours following endoscopic sphincterotomy or delayed surgery after 6 weeks. Peritoneal plasmin system is known to be an important factor in peritoneal healing and adhesion formation. Measurement of tissue concentrations of tissue-type plasminogen activator and its specific activity, urokinase-type plasminogen activator, and plasminogen activator inhibitor type 1 are thought to be helpful to show peritoneal adhesions after endoscopic sphincterotomy.

Alterations in pancreatic blood have been implicated in pancreatic inflammation and pain. Several modalities have been used to assess pancreatic blood flow although some of these methods are invasive, use ionising radiation or intravenous contrast media. This is the first study to utilise non-invasive magnetic resonance imaging to quantify flow within arteries supplying the pancreas and pancreatic perfusion is response to secretin stimulation.

The causes of acute pancreatitis in Finland are alcohol overuse (60%), cholecystolithiasis (20%) and idiopathic (i.e. etiology unknown)(20%). Acute pancreatitis may recur in over half of cases and may be fatal in severe cases in 30%. Majority of idiopathic pancreatitis are caused by microlithiasis in gall bladder. The purpose of this randomized study is to prevent recurrence of idiopathic pancreatitis by performing laparoscopic cholecystectomy compared to non-operative group in 2 years follow-up of patients.

Pancreatico-duodenectomy is one of the commonly performed procedure for periampullary/distal cholangio/head of pancreas carcinoma. Post operative pancreatitis is an emerging concept, recently being studied as one of the most important contributing factor of Post-operative pancreatic fistula, which is one of the major complication of pancreatoduodenectomy. Rectal indomethacin, a type of non-steroidal anti-inflammatory drug, when given in a single dose has been shown to prevent pancreatitis in patients undergoing ERCP. In this study, we will be administering rectal indomethacin at the time of induction of anesthesia to the experimental arm of the study and compare the results in terms of incidence of post-operative pancreatitis in the two groups.

Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is the most common, serious complication of ERCP. More than 500,000 ERCP procedures are performed from which 25,000 cases of PEP occur in the U.S.A. annually. PEP accounts for significant morbidity and health care expenditures. While symptoms of PEP arise immediately after ERCP, they are non-specific. Consequently, unnecessary admissions of outpatients without PEP and inadvertent discharge of outpatients with PEP from ERCP recovery are common. An accurate, confirmatory test for diagnosis of PEP immediately after ERCP is lacking. Actim Pancreatitis (Medix Biochemica) is a urine trypsinogen-2 dipstick test (UTDT) that uses trypsinogen-2 as a biomarker for acute pancreatitis. Urine Trypisinogen-2 Dipstick test (UTDT) is a simple, inexpensive test with promising preliminary data for accuracy for immediate diagnosis of PEP. Prior studies of ITDT test characteristics lack rigorous scientific design. Investigators will enroll 1825 ERCP outpatients at our institution in a prospective cohort study. A pre-ERCP UTDT test and diagnostic UTDT 2 hours after the ERCP will be performed. Patients with a positive baseline UTDT will be followed clinically as part of this study without 2 hour testing. Care providers and study primary investigators will be blinded to the 2 hour UTDT results. Baseline, intra-procedure and recovery room clinical data will be recorded. Diagnosis of PEP will be made blinded to the UTDT result. Admission status for PEP will be assessed by review of records and phone/e-mail contact 5 days and 30 days after ERCP procedure. Sensitivity and specificity of 2 hour post ERCP UTDT for the diagnosis of PEP will be calculated. Aims: 1) To determine the test characteristics of UTDT for the diagnosis of PEP 2 hours after completion of ERCP. 2) To identify and describe patients with baseline UTDT positivity, in whom this test offers limited utility. Specific Aims: Primary Aim 1.1 To determine the test characteristics (sensitivity and specificity) of the UTDT for the diagnosis of PEP: Hypotheses: UTDT is a sensitive and specific test for the diagnosis of PEP for patients undergoing ERCP. At a cutpoint for a negative test of <50ug/L, UTDT will be accurate at 2 hours post ERCP in patients whose baseline test is negative.

This is a investigator-initiated, single-center, prospective study to evaluate endoscopic ultrasound (EUS) as a diagnostic test for chronic pancreatitis (CP). EUS detects abnormalities of the pancreas that may represent scarring from CP. The validation of any new test requires a comparison with the best available reference standards. There is no true "gold standard" for diagnosis of CP; however, pancreatic function testing (PFT) is highly sensitive for exocrine dysfunction as a surrogate for early fibrosis, and is widely considered the non-histologic gold standard. There are no well-designed prospective studies comparing EUS with PFT as reference standard. EUS detects parenchymal and ductal features of CP said to correlate with fibrosis. We hypothesize that a predominance of parenchymal fibrosis results in diminished acinar-cell secretion of enzymes. Conversely, a predominance of ductal fibrosis results in impairment of ductal secretion of bicarbonate. Because secretin and cholecystokinin (CCK) PFTs measure unique aspects of pancreatic function (duct-cell and acinar-cell function, respectively), the use of both hormonal stimulants will allow the most comprehensive investigation of the significance of EUS features. There are no studies comparing EUS with combined or dual performance of secretin and CCK PFTs. The primary objective of this study is to determine the test characteristics of EUS for diagnosis of CP compared with dual secretin- and CCK- stimulated PFTs as reference standard. Secondary objectives include to: 1. Determine the optimal number and relative functional importance of specific EUS criteria, 2. Compare the test characteristics of linear- and radial-array EUS. 190 patients evaluated for pancreatitis or pancreatic-type abdominal pain will undergo the "new test" (radial and linear EUS) and the reference standard (CCK and secretin PFTs). The EUS examinations will be videotaped and interpreted in a blinded fashion. EUS scores will be compared with PFT results to allow the calculation of sensitivity and specificity of linear and radial EUS. Receiver operating characteristics (ROC) analysis will be used to determine the optimal number of EUS criteria for diagnosis.

The purpose of this study is to evaluate the incidence of complications with the isolated Roux-en-Y reconstruction after pancreaticoduodenectomy in pancreatic tumor and periampullary tumor patients. A prospective randomized controlled trial was conducted to compare the incidence of complications with isolated Roux-en-Y reconstruction with those of Billroth-II-type reconstruction after pancreaticoduodenectomy.
