Pancreatic Elastography Predicts Endoscopic Secretin-Pancreatic Function Test Result in Patients With Early Changes of Chronic Pancreatitis: A Prospective, Cross-Sectional, Observational Study.

Introduction: The endoscopic pancreatic function test (ePFT) has been proposed for the evaluation of patients with suspected early chronic pancreatitis (CP) in the appropriate clinical context, but the cost and duration of the test limit its clinical applicability. Pancreatic secretion decreases as pancreatic fibrosis develops in CP. Pancreatic fibrosis can be quantified by endoscopic ultrasound-elastography (EUS-E).

Emergent endoscopic ultrasound-guided cholecystoduodenostomy does not prevent R0 resection in a pancreaticoduodenectomy for pancreatic cancer.

Endoscopic ultrasound-guided biliary drainage, mainly choledochoduodenostomy, is commonly used as rescue therapy after Endoscopic Retrograde Cholangiopancreatography (ERCP) in malignant distal biliary obstruction due to un-resectable pancreatic cancer. An alternative when the cystic duct is patent and choledochoduodenostomy is not feasible is performing an Endoscopic Ultrasound-gallbladder drainage. The advent of the Lumen Apposing Metal Stents (LAMS) has shortened and simplified this procedure.

Pancreatic Cancer Malnutrition and Pancreatic Exocrine Insufficiency in the Course of Chemotherapy in Unresectable Pancreatic Cancer.

Unlabelled: Malnutrition and cachexia are common in patients with advanced pancreatic ductal adenocarcinoma (PDAC) and have a significant influence on the tolerance and response to treatments. If timely identified, malnourished PDAC patients could be treated to increase their capacity to complete the planned treatments and, therefore, possibly, improve their efficacy. The aim of this study is to assess the impact of nutritional status, pancreatic exocrine insufficiency (PEI), and other clinical factors on patient outcomes in patients with advanced PDAC.

Acid suppression therapy, gastrointestinal bleeding and infection in acute pancreatitis - An international cohort study.

Background: Acid suppressing drugs (ASD) are generally used in acute pancreatitis (AP); however, large cohorts are not available to understand their efficiency and safety. Therefore, our aims were to evaluate the association between the administration of ASDs, the outcome of AP, the frequency of gastrointestinal (GI) bleeding and GI infection in patients with AP.

Methods: We initiated an international survey and performed retrospective data analysis on AP patients hospitalized between January 2013 and December 2018.

Endoscopic ultrasound-based multimodal evaluation of the pancreas in patients with suspected early chronic pancreatitis.

Background: Diagnosis of early chronic pancreatitis is a clinical challenge and hindered by the lack of a gold standard. Endoscopic ultrasound (EUS) and the endoscopic pancreatic function test (ePFT) are the most sensitive morphological and functional methods in this setting. EUS-elastography allows for the quantification (strain ratio) of pancreatic fibrosis, and the dynamic evaluation of the main pancreatic duct compliance provides additional information.

Endoscopic drainage with local infusion of antibiotics to avoid necrosectomy of infected walled-off necrosis.

Background: Current treatment of infected pancreatic necrosis (IPN) follows a step-up approach. Our group designed a step-up protocol that associates endoscopic drainage with local infusion of antibiotics through transmural nasocystic catheter. Aim of our study was to evaluate our step-up protocol for IPN in terms of proportion of patients avoiding necrosectomy.

Differential diagnosis of solid pancreatic masses.

Solid pancreatic lesions include mainly adenocarcinoma, neuroendocrine tumors pancreatic cystic neoplasms with solid component, solid pseudopapillary tumor, pancreatoblastoma, pancreatic lymphoma, and pancreatic metastasis. The most frequent pancreatic lesion is the adenocarcinoma, representing between 70% and 95% of all solid pancreatic neoplasm. The diagnosis of these lesions can be a challenge and currently, there are different imaging techniques such as CT scan, EUS and MRI with high sensitivity and specificity.

Exocrine Pancreatic Insufficiency Following Acute Pancreatitis: Systematic Review and Meta-Analysis.

Background/objectives: The epidemiology of exocrine pancreatic insufficiency (EPI) after acute pancreatitis (AP) is uncertain.

EUS-FNA in cystic pancreatic lesions: Where are we now and where are we headed in the future?

EUS-FNA is often performed in the evaluation of Cystic Pancreatic Lesions (CPL) for a better preoperative characterization. The objective is to identify premalignant lesions as Mucinous Cystic Neoplasms, and/or a malignant transformation of them (adenocarcinoma). The role of cytological evaluation in this setting is discouraging and intracystic markers analysis, mainly CEA, lacks of a good specificity for the detection of mucinous neoplasms.

Increased Risk of Mortality Associated With Pancreatic Exocrine Insufficiency in Patients With Chronic Pancreatitis.
