A Phase II MULTICENTRE Trial of Needle Based Laser Confocal Endomicroscopy of Cystic and Solid Tumours...
Pancreatic CystSerous Cystadenoma3 moreA multicentre phase II study to determine the safety and efficacy of EUS-guided nCLE in patients with suspected cystic tumours of the pancreas in whom endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is clinically indicated. Patients will be recruited sequentially to undergo nCLE as part of their routine diagnostic evaluation, followed by standard surveillance. This part of the study will recruit 60 patients.
Pancreatic Cyst Fluid Glucose: New Armamentarium in the Diagnosis of Mucinous Pancreatic Cystic...
Pancreatic Cyst FluidAll participants undergoing radiological imaging and found to have pancreatic cyst of size > 2cm will be subjected to EUS (Endoscopic ultrasound) examination and cystic fluid will be aspirated for analysis, including cystic fluid Glucose, CEA, amylase. Morey's biopsy will be done in the cases feasible for biopsy. The sensitivity and specificity of cystic fluid glucose level will be analysed taking CEA (carcinoembryonic antigen) level with EUS findings, amylase level as gold standard for diagnosis, in cases with no surgical management.
Laser Tissue Welding - Distal Pancreatectomy Sealing Study
Pancreatic TumorBenign13 moreThe laser tissue welding device is intended for use in patients requiring sealing of the pancreas after partial pancreatectomy, and including those patients who are fully heparinized or have hemodilutional coagulation failure. The hypothesis is that the laser tissue welding device is safe and effective in sealing the pancreas, thereby decreasing the blood loss (operative and post-operative), and pancreatic juice leakage for patients when the Laser Tissue Welding device is used after pancreatic resection.
Needle-based Confocal Laser Endomicroscopy on Pancreatic Cystic Lesions
Pancreatic CystsPancreatic Mucinous-Cystic Neoplasm4 moreThe study is based on a multi-center approach of needle based confocal laser endomicroscopy (nCLE) combined with endoscopic ultrasound (EUS) and EUS-guided fine needle aspiration (FNA) to evaluate pancreatic cystic lesions (PCL), in order to obtain a correct histopathological diagnosis.After detection of PCL, certain morphological EUS features allow the discrimination of specific cyst types. Additionally, EUS-FNA is recommended as the first-line procedure whenever pathological diagnosis is required; however the procedure has its drawbacks, mainly represented by the relatively low negative predictive value in diagnosing pancreatic cancer. In this case a more precisely diagnostic tool is required; the potential role of CLE has been explored in gastrointestinal (GI) pathology showing good accuracy for predicting the final histopathological diagnosis based on immediate evaluation of tissue and vascular patterns. Although the clinical impact of nCLE for the decision making algorithms in cystic pancreatic neoplasm has not yet been described, the hypothesis is that EUS-nCLE could allow targeted tissue sampling of cystic pancreatic neoplasms resulting in more accurate diagnosis. The aim of the study is to describe the clinical impact of nCLE for the clinical decision management algorithm based on EUS, EUS-FNA and/or EUS-CLE imaging criteria for cystic pancreatic neoplasms, while evaluating also the feasibility and safety of nCLE examination.
Endoscopic Ultrasonography-guided Double Ethanol Lavage for Pancreatic Cysts: a Prospective Cohort...
Pancreatic Mucinous-Cystic NeoplasmDue to widespread use of cross-sectional imaging modalities, pancreatic cysts are common in abdominal image. These lesions encompass a wide spectrum, ranging from benign to malignant. The diagnosing specific type of cystic lesion is limited in spite of recent advances of diagnostic modalities. Surgical resection is generally recommended for malignant and potentially malignant lesions. However, surgical resection has significant morbidity and sometimes mortality. Recently, a few study of EUS-guided ethanol lavage for cystic tumors of the pancreas reported that complete resolution was achieved in only one-third of patients. Ethanol lavage of pancreatic cysts may be alternative method to surgical resection. The purpose of this study is the double ethanol lavage is a safe and effective method for treatment in those with the indeterminate pancreas cysts.
Safety and Efficacy of an Ablation Catheter for the Treatment of Pancreatic Premalignant Cyctic...
Pancreatic CancerPancreatic Neuroendocrine Tumor2 moreThis study aims to evaluate the safety and efficacy of new ablation catheter developed by MEDICAL TAEWOONG for the treatment of pancreatic premalignant and early malignant cystic lesion. The ablation is performed using EUSRA needle and radiofrequncy waves under ultrasound imaging. The method will be exaimened on patients who are candidates for surgical intervention and to examine the ability of the method to serve as an alternative to surgical intervention.
A Phase II Multicentre Trial of Endoscopic Ultrasound Guided Radiofrequency Ablation of Cystic Tumours...
Pancreatic CystUp to 13.5% of patients that undergo a magnetic resonance imaging (MRI) scan of their abdomen without pancreatic symptoms are found to have an incidental pancreatic cyst, with the frequency increasing with age. In a post-mortem series, 25% of patients had a pancreatic cyst, of which 32% were potentially premalignant and 3% malignant. Premalignant cysts are currently either observed or removed surgically according to international guidelines. Observation is associated with significant anxiety for patients and a growing cost to the National Health Service, while surgery for this usually benign condition is associated with not insignificant morbidity and mortality. Premalignant pancreatic cysts may be indolent for a number of years before malignant transformation, creating a window of opportunity for minimally invasive intervention and cure. New early treatment options for premalignant tumours are urgently required. This study will evaluate the safety and efficacy of a novel minimally invasive technique for the treatment of pancreatic cystic tumours; endoscopic ultrasound guided radiofrequency ablation (EUSRFA). If successful it will offer an alternative to long term observation or surgery for patients with this condition.
Usefulness of Contrast Enhanced Harmonic Endoscopic Ultrasound for Pancreatic Cysts
Pancreatic CystThe study evaluates the role of contrast-enhanced harmonic endoscopic ultrasound (CH-EUS) for the differentiation of the pancreatic cysts and their malignant potential.
Biospecimens for Identification of Diseases of the Pancreas.
Pancreatic CancerChronic Pancreatitis3 moreThis proposed project is designed to collect data and specimens from patients/subjects presenting to the University of Michigan with a disease affecting the pancreas (or specific control populations). This protocol is focused on collecting data, blood samples, and tissue on subjects with pancreatic diseases, including pancreatic cancer, pancreatic cysts, pancreatitis, diabetic controls, jaundice/biliary obstruction controls, and otherwise healthy controls. We are collecting up to 50 mls of blood for research purposes only. Plasma, serum and buffy coat are collected and stored according to strict SOPs.
DNA-mutation Analysis in Cyst Fluid of Suspected Intraductal Papillary Mucinous Neoplasia of the...
Pancreas CystDiagnostic tools are needed to identify mucinous cysts for further evaluation or follow-up respectively to identify cysts with HGD or invasive cancer at an early stage for surgical resection. Molecular genetic analysis of pancreatic cyst fluid is a new but rapidly evolving method to identify KRAS/GNAS oncogenic driver mutations in mucinous cysts and to identify tumour suppressor gene mutations which are involved in advanced cysts with HGD or carcinoma. The ongoing ZYSTEUS-study tries to implement DNA mutation analysis by Next Generation Sequencing in the diagnostic algorithm of pancreas cyst evaluation. The first aim is to distinguish mucinous from non-mucinous cysts. The second aim is to define relevant tumour suppressor gene mutations which are relevant to distinguish between LGD and HGD/carcinoma in mucinous cysts.
