Filter by:The existing comprehensive diagnostic system for autoimmune pancreatitis (AIP) is complex, with multidimensional clinical information including morphological changes and a lack of specific biomarkers. Endoscopic ultrasound (EUS) can provide all the elements for morphological diagnosis of AIP, but the long learning curve and large observer differences make it difficult to popularize and promote. The cooperation units of the three regions in this project have found in the early stage that Klebsiella pneumoniae (KP) induced follicular helper T cells (Tfh) activation is an important mechanism of AIP, but the identification of pathogenic components of the strain and clinical validation need to be explored. We have established a national multicenter AIP queue in the early stage and extracted EUS audio-visual features to establish a scoring model, but intelligent assistance is still needed to improve efficiency. Therefore, we plan to integrate gut microbiota, Tfh activation markers, and EUS imaging features to establish an AI assisted multimodal diagnostic system for AIP. This study will collaborate across multiple centers to identify and validate the components that induce Tfh activation in KP bacterial cells, to extract EUS pancreatic ultrasound features and optimize artificial intelligence assisted diagnostic algorithms, and to establish and validate an artificial intelligence assisted multimodal diagnostic system based on clinical information, biomarkers, and EUS. The aim of this study is to provide new diagnosis and treatment evaluation methods for AIP with high accuracy, convenience, and easy promotion for clinical practice.
The purpose of collecting this data is to continue to learn more about the EchoTip AcuCore and the device's ability to produce the desired favorable effect and if there are any undesired outcomes that may be related to the EchoTip AcuCore.
The goal of this observational, retrospective study is to learn about cancer risk in autoimmune pancreatitis (AIP) patients. The main questions it aims to answer are: - Do patients with AIP have higher incidence of cancer in comparison to general population? - What is the overall prevalence of cancer in AIP patients? - What are the characteristics of AIP patients associated with the incidence of cancer?
Endoscopic ultrasound (EUS)-guided fine needles with side fenestrations are used to collect aspirates for cytology analysis and biopsy samples for histologic analysis. The investigators conducted a large, multicenter study to compare the accuracy of diagnosis via specimens collected with fine-needle biopsy (FNB) versus fine-needle aspiration (FNA) for patients with lesions requiring immunohistochemistry (IHC) pathological diagnosis.
We aim to develop an EUS-AI model which can facilitate clinical diagnosis by analyzing EUS pictures and clinical parameters of patients.
Study objective: To describe the microflora characteristics of the pancreatic solid lesions via the tissue acquired via the endoscopic ultrasound-guided fine needle aspiration/biopsy (EUS-FNA/B). Study design: This is a prospective observational study.
The diagnosis of pancreas diseases is based on a combination of clinical signs, symptoms, and laboratory tests, but mainly on imaging techniques such as computed tomography (CT) and magnetic resonance (MR). However, CT/MR have variable sensitivity and specificity, with certain disadvantages. Endoscopic ultrasound with elastography is an important resource with higher diagnostic accuracy in assessing solid pancreas lesions. Shear wave velocities of healthy parenchyma, acute, chronic and autoimmune pancreatitis, neoplastic lesions of the pancreas must be evaluated and compared.
Autoimmune pancreatitis (AIP) is a special type of chronic pancreatitis mediated by autoimmunity. The classic manifestation of AIP is diffuse pancreatic enlargement, some of which are characterized by focal enlargement. Clinically, it is divided into diffuse AIP (DAIP) and focal AIP (FAIP) according to morphology. FAIP can be clinically manifested as obstructive jaundice, peripancreatic lymphadenopathy and vascular involvement, which may mimic pancreatic cancer (PC). CT/MRI is the important imaging tool for diagnosing pancreatic diseases. However, due to the overlap of the imaging features of FAIP and PC, it is challenging to differentiate the two by CT/MRI. Endoscopic ultrasound (EUS) can clearly display the pancreatic parenchyma and pancreatic duct system and has become a routine modality for the evaluation of pancreatic diseases. The aim of this study is to construct a diagnosis model for distinguishing between FAIP and PC by comparing the EUS characteristics of the two, and further validate its diagnostic efficacy.
According to the reported histological procurement yield of the end-cutting needles, the investigators supposed that the use of EUS-FNB in probable AIP patients, generally aimed only to rule-out malignancy, could provide histological tissue samples useful in enhancing the diagnostic level reached without histology, or defining the type of AIP.
The aim of this study is to compare the diagnostic accuracy of two EUS-guided tissue acquisition devices; the 19G Echotip Ultra Fine Needle Aspiration (FNA) device and the 20G Echotip ProCore Fine Needle Biopsy (FNB) device for the diagnosis of autoimmune pancreatitis.
