BACKGROUND: Autoimmune Pancreatitis (AIP) is a rare chronic inflammatory disease affecting the pancreas. Chronic pancreatic inflammation represents a risk factor for pre-neoplastic conditions such as Intraductal Papillary Mucinous Neoplasia (IPMN). Due to the rarity of AIP, the incidence, and clinical features of IPMN occurring in AIP patients remains unknown. AIMS: In the present study we aimed to explore the relationship between AIP and IPMN and to characterize the clinical features and outcomes of IPMN occurring in the context of AIP...

BACKGROUND: The management of branch-duct type intraductal papillary mucinous neoplasms (BD-IPMN) varies in existing guidelines. This study investigated the optimal surveillance protocol and safe discontinuation of surveillance considering natural history in non-resected IPMN, by systematically reviewing the published literature. METHODS: This review was guided by PRISMA. Research questions were framed in PICO format "CQ1-1: Is size criteria helpful to determine surveillance period? CQ1-2: How often should surveillance be carried out? CQ1-3: When should surveillance be discontinued? CQ1-4: Is nomogram predicting malignancy useful during surveillance?"...

OBJECTIVE: To investigate profiles of circulating immune signatures in healthy controls and chronic pancreatitis patients (CP) with and without a preceding history of acute pancreatitis (AP). METHODS: We performed a phase 1, cross-sectional analysis of prospectively collected serum samples from the PROspective Evaluation of Chronic Pancreatitis for EpidEmiologic and Translation StuDies (PROCEED) study. All samples were collected during a clinically quiescent phase...

OBJECTIVE: Serous cystic neoplasms (SCN) are benign pancreatic cystic neoplasms that may require resection based on local complications and rate of growth. We aimed to develop a predictive model for the growth curve of SCNs to aid in the clinical decision making of determining need for surgical resection. METHODS: Utilizing a prospectively maintained pancreatic cyst database from a single institution, patients with SCNs were identified. Diagnosis confirmation included imaging, cyst aspiration, pathology, or expert opinion...

Previously we reported that a novel αvβ6-specific peptide-drug conjugate (SG3299) could eliminate established human pancreatic ductal adenocarcinoma (PDAC) xenografts. However the development of effective therapies for PDAC, which is an essential need, must show efficacy in relevant immunocompetent animals. Previously we reported that the KPC mouse transgenic PDAC model that closely recapitulates most stages of development of human PDAC, unlike in humans, failed to express αvβ6 on their tumours or metastases...

BACKGROUND: Modified FOLFIRINOX (mFOLFIRINOX) is one of the standard first-line therapies in borderline resectable pancreatic cancer (BRPC) and locally advanced unresectable pancreatic cancer (LAPC). However, there is no globally accepted second-line therapy following progression on mFOLFIRINOX. METHODS: Patients with BRPC and LAPC (n = 647) treated with first-line mFOLFIRINOX between January 2017 and December 2020 were included in this retrospective analysis...

BACKGROUND: Acute pancreatitis (AP) often presents with varying severity, with a small fraction evolving into severe AP, and is associated with high mortality. Complications such as intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are intricately associated with AP. OBJECTIVE: To assess the clinical implications and predictors of ACS in AP patients. METHODS: We conducted a retrospective study using the National Inpatient Sample (NIS) database on adult AP patients, further stratified by the presence of concurrent ACS...

BACKGROUND: Psychiatric comorbidity measured by screening instruments is common in patients with chronic pancreatitis (CP) but whether this accurately reflects clinical diagnosis of psychiatric comorbidity is unknown and the prevalence of psychotropic medication prescription in CP remains largely unexplored. METHODS: Adult patients (≥18 years) with definite CP were enrolled and completed the Hospital Anxiety and Depression Scale (HADS). Demographics, clinical characteristics and medications were retrieved from case report forms and the electronic health record (EHR)...

OBJECTIVE: Hemin, a heme oxygenase 1 activator has shown efficacy in the prevention and treatment of acute pancreatitis in mouse models. We conducted a randomized controlled trial (RCT) to assess the protective effect of Hemin administration to prevent post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) in patients at risk. METHODS: In this multicenter, multinational, placebo-controlled, double-blind RCT, we assigned patients at risk for PEP to receive a single intravenous dose of Hemin (4 mg/kg) or placebo immediately after ERCP...

BACKGROUND/OBJECTIVES: The outcomes of patients with intraepithelial neoplasia at the pancreatic transection margin after pancreatic cancer surgery remain unclear. We evaluated the clinical impact of pancreatic transection margin status. METHODS: This retrospective observational study included 171 patients who underwent surgery for pancreatic ductal adenocarcinoma between January 2008 and December 2019. Patients were classified into three groups: negative pancreatic transection margin (group N), positive low-grade (group L), and positive high-grade (group H) intraepithelial neoplasia...

BACKGROUND AND AIM: Endoscopic ultrasound (EUS)-guided endoscopic necrosectomy is an effective and minimally invasive treatment for walled-off pancreatic necrosis (WON). This study investigated the factors affecting the time interval of EUS-guided WON necrosectomy. METHODS: Patients who received EUS-guided necrosectomy in the Endoscopy Center of the First Affiliated Hospital of Chongqing Medical University in the past 5 years were retrospectively analyzed. Data including general information, etiology, blood biochemical indexes, physical signs, CT severity grade, location, size, solid necrotic ratio, type and number of stents, and immediate necrosectomy were collected to explore the relationships between these factors and the interval of endoscopic necrosectomy...

BACKGROUND: Objectives: To investigate communication clarity and understanding at the time of pancreatic adenocarcinoma (PDAC) diagnosis and whether they can influence patient engagement and compliance. METHODS: Consecutive PDAC patients were enrolled at the time of diagnosis after obtaining informed consent in a single-center study. The patients completed a validated scale (PHE-s®), and the understanding rate was assessed using standardized tools. Patient compliance was evaluated, and the correlation between the PHE-s®, understanding, and compliance was calculated...

BACKGROUND: Acute biliary pancreatitis (ABP) is the most common type of acute pancreatitis. However, the effect of serum triglyceride (TG) levels on the severity of ABP remains unclear. The aim of this study was to assess the correlation between serum TG levels and the severity of ABP. METHODS: Data from 526 ABP patients was analyzed in this study. The patients were divided into normal and elevated groups according to the TG level measured within 24 h after admission, and the elevated group was further divided into mild, moderate, and severe elevated groups...

Pancreatic cancer is one of digestive tract cancers with high mortality rate. Despite the wide range of available treatments and improvements in surgery, chemotherapy, and radiation therapy, the five-year prognosis for individuals diagnosed pancreatic cancer remains poor. There is still research to be done to see if immunotherapy may be used to treat pancreatic cancer. The goals of our research were to comprehend the tumor microenvironment of pancreatic cancer, found a useful biomarker to assess the prognosis of patients, and investigated its biological relevance...
