Filter by:To prospectively define the natural history and the clinical, laboratory and histomorphometric features of chronic pancreatitis (CP) of varying etiology. To identify clinical and laboratory parameters that correlate with the pathophysiologic state in patients with CP. To quantify the behavioral abnormalities associated with CP. To determine psychological and behavioral correlates of CP disease progression and outcomes.
The purpose of the study is to evaluate the enzyme activity and safety of pancrelipase in patients with severe Exocrine Pancreatic Insufficiency (EPI)
The purpose of this study is to evaluate the safety and effectiveness of RG1068 (synthetic human secretin) with MRCP in subjects with abnormalities of the pancreas.
This is a triple-blind, parallel group, randomized controlled trial to assess the benefit of triamcinolone injection as a therapeutic measure for control of chronic pancreatitis pain. The treatment group will undergo EUS-CPB with bupivicaine plus triamcinolone ("therapeutic block"). There control group will undergo EUS-CPB with bupivicaine alone ("diagnostic block").
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 clarify whether resecting pylorus-ring decreases delayed gastric emptying after pancreaticoduodenectomy and improves postoperative quality of life (QOL).
The phenomenon that oral glucose elicits a higher insulin response than does intravenous (iv) glucose, even at identical plasma glucose (PG) profiles (isoglycemia), is called the incretin effect. In type 2 diabetes mellitus (T2DM) the incretin effect has been shown to be markedly reduced or even abolished. It is not known whether the reduced incretin effect in T2DM is a primary event leading to T2DM or if it is merely a consequence of the diabetic state. To answer this question the investigators plan to estimate the incretin effect in 8 patients with secondary diabetes mellitus (DM) to chronic pancreatitis (CP) and compare it to the incretin effect of 8 patients with CP and normal glucose tolerance (NGT). Eight patients with T2DM and 8 healthy control subjects are studied for comparison. The incretin effect is measured by a 50-g oral glucose tolerance test and an isoglycemic intravenous glucose infusion.
The purpose of this study is to determine which stent type is effective in the decrease of postoperative stay and complications across pancreaticojejunostomy after pancreaticoduodenectomy.
The purpose of the study is to determine the best evaluation for patients with idiopathic (unexplained) pancreatitis.
The role of teleradiology has far reaching implications for the health of remote and underserved populations. The ability to coordinate radiographic evaluation and diagnosis from a distance has the potential to raise the standard of patient care throughout the world. Perhaps the safest and most cost effective mode of teleradiology today is telesonography. The current project attempts to determine the extent that telesonography improves the standard of care within a rural government-run primary clinic within the Dominican Republic. The work reported herein is intended to compare the use of telesonography to the current standard of sonographic examination (referral to government hospital 60km from target clinic). The study was conducted by randomly assigning 100 patients with clinical indications for sonographic examination into experimental and control groups. Following a 60-day implementation period, the following research questions will be addressed: 1) To what extent does the use of asynchronous telesonography increase the percentage of definitive diagnoses based on the total number of scans (definitive diagnoses / total number of scans)? 2) To what extent does the use of asynchronous telesonography increase the continuity of care for patients? 3) To what extent does the elapsed time between scanning and final radiological interpretation decrease with the use of asynchronous telesonography? This study will also look at the history of telemedicine / telesonography and its dissemination into the mainstream practice of medicine, explore training protocols that may be used to assist others to establish new telesonography programs in a developing nations, and discuss both advances and persistent barriers to the implementation of telesonography programs. Hypothesis: The use of a store-and-forward telesonography system in this setting will increase the speed and number of final diagnoses per scan received by the target clinic and will increase the continuity of care by increasing the number and speed of follow-up appointments to the target clinic.
