OBJECTIVE: A significant number of patients experience early recurrence after surgical resection for pancreatic ductal adenocarcinoma (PDAC), negating the benefit of surgery. The present study conducted clinicopathologic and metabolomic analyses to explore the factors associated with the early recurrence of PDAC. MATERIALS AND METHODS: Patients who underwent pancreatectomy for PDAC at Kagawa University Hospital between 2011 and 2020 were enrolled. Tissue samples of PDAC and nonneoplastic pancreas were collected and frozen immediately after resection...

OBJECTIVES: The elemental diet (ED) is a formula to support nutritional status without increasing chylous burden. This study evaluates the efficacy of early ED feeding after pancreatoduodenectomy (PD). MATERIALS AND METHODS: A prospective phase II study of consecutive patients who underwent PD with early ED feeding was conducted. Patient backgrounds, surgical outcomes, and ED feeding tolerability were compared with a historical cohort of 74 PD patients with early enteral feeding of a low residue diet (LRD)...

OBJECTIVES: Signal intensity ratio of pancreas to spleen (SI ratiop/s) on fat-suppressed T1-weighted images of magnetic resonance imaging has been associated with pancreatic exocrine function. We here investigated the predictive value of the SI ratiop/s for the development of nonalcoholic fatty liver disease (NAFLD) after pancreaticoduodenectomy (PD). MATERIALS AND METHODS: This study comprised 208 patients who underwent PD. NAFLD was defined as a liver-to-spleen attenuation ratio of <0...

OBJECTIVES: Identifying patients with severe hypertriglyceridemia (HTG) who are prone to developing hypertriglyceridemic pancreatitis (HTGP) is essential for facilitating preventative interventions. This research aims to explore which part of the HTG patients is easy to develop into HTGP. MATERIALS AND METHODS: An observational cohort study was conducted in patients with serum triglycerides (TGs) ≥ 5.65 mmol/L. Propensity score matching (PSM) and logistic regression were used to adjust for potential confounding factors...

A few pediatric cases of abdominal paragonimiasis have been described. Here we describe a case of pulmonary and abdominal paragonimiasis with involvement of the pancreas in a 9-year-old boy. The aim of this study was to analyze the clinical and radiological features of pancreatic paragonimiasis in children and raise the awareness of this disease.

OBJECTIVES: We set out to predict whether nonsurgical treatment is likely to succeed in removing pancreatic stones in a given patient and also to determine an optimal maximal number of extracorporeal shock wave lithotripsy (ESWL) sessions for treatment of pancreatolithiasis in that patient. MATERIALS AND METHODS: We ascertained the number of ESWL sessions for each of 164 patients undergoing that treatment for pancreatolithiasis between 1992 and 2020. Median follow-up duration was 31 months (range, 0-239), median age was 58 years (22-83), and the male to female ratio was 5...

BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) is a deadly disease due to the lack of early detection. Because chronic pancreatitis (CP) patients are a high-risk group for pancreatic cancer, this study aimed to assess the differential miRNA profile in pancreatic tissue of patients with CP and pancreatic cancer. METHODS: MiRNAs were isolated from formalin-fixed paraffin-embedded pancreatic tissue of 22 PDAC patients, 18 CP patients, and 10 normal pancreatic tissues from autopsy (C) cases and processed for next-generation sequencing...

OBJECTIVES: We aimed to compare the efficacy and toxicity of palliative chemotherapy in elderly patients with pancreatic ductal adenocarcinoma (PDAC) with those in younger patients. METHODS: A total of 60 patients with locally advanced or metastatic PDAC who received FOLFIRINOX or nab-paclitaxel plus gemcitabine at our institution from January 2014 to December 2021 were analyzed. Patients 70 years or older were classified into an elderly group. RESULTS: The elderly group included 16 patients (26...

Pancreatic ductal adenocarcinoma (PDAC) stands as one of the most lethal diseases globally, boasting a grim 5-year survival prognosis. The origin cell and the molecular signaling pathways that drive PDAC progression are not entirely understood. This review comprehensively outlines the categorization of PDAC and its precursor lesions, expounds on the creation and utility of genetically engineered mouse models used in PDAC research, compiles a roster of commonly used markers for pancreatic progenitors, duct cells, and acinar cells, and briefly addresses the mechanisms involved in the progression of PDAC...

OBJECTIVES: Patients with pancreatic disease(s) have a high risk of developing diabetes mellitus (DM). Diabetes mellitus is associated with adverse postoperative outcomes. This study aimed to investigate the prevalence and effects of DM on postoperative outcomes in pancreatic surgery. METHODS: Subgroup analysis of a prospective cohort study conducted at an academic hospital. Patients undergoing pancreatoduodenectomy between January 2019 and November 2022 were included and screened for DM preoperatively using glycated hemoglobin (HbA1c)...

OBJECTIVES: Most patients with intraductal papillary mucinous neoplasms (IPMNs) are diagnosed with a solitary lesion; however, the presence of skip lesions, not appreciable on imaging, has been described. Postoperatively, these missed lesions can continue to grow and potentially become cancerous. Intraoperative pancreatoscopy (IOP) may facilitate detection of such skip lesions in the remnant gland. The aim of this scoping review was to appraise the evidence on the role of IOP in the surgical management of IPMNs...

There exists no cure for acute, recurrent acute or chronic pancreatitis and treatments to date have been focused on managing symptoms. A recent workshop held by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) focused on interventions that might disrupt or perhaps even reverse the natural course of this heterogenous disease, aiming to identify knowledge gaps and research opportunities that might inform future funding initiatives for NIDDK. The breadth and variety of identified active or planned clinical trials traverses the spectrum of the disease and was conceptually grouped for the workshop into behavioral, nutritional, pharmacologic and biologic, and mechanical interventions...

OBJECTIVES: Secondary infections due to transmission via the duodenoscope have been reported in up to 3% of endoscopic retrograde cholangiopancreatographies. The use of single-use duodenoscopes has been suggested. We investigate the cost-effectiveness of these duodenoscopes use in cholangiopancreatography. MATERIALS AND METHODS: A cost-effectiveness analysis was implemented to compare the performance of cholangiopancreatographies with reusable duodenoscopes versus single-use duodenoscopes...

BACKGROUND: The International Cancer of the Pancreas Screening Consortium recommended annual imaging for individuals at increased risk for developing a pancreatic ductal adenocarcinoma (PDAC) who did not have concerning pancreatic findings or a cyst <3 cm without worrisome features. We aimed to determine if 3-cm cyst size accurately predicted advanced precursor lesions in high-risk individuals undergoing surveillance. METHODS: Imaging for high-risk individuals (HRIs) undergoing PDAC surveillance from 2007 to 2021 was reviewed and pancreatic abnormalities were recorded including dominant cyst size and number of cysts...
