BACKGROUND: The management of acute necrotizing pancreatitis (ANP) has changed dramatically over the past 20 years including the use of less invasive techniques, the timing of interventions, nutritional management, and anti-microbial management. This study sought to create a core outcome set (COS) to help shape future research by establishing a minimal set of essential outcomes that will facilitate future comparisons and pooling of data, while minimizing reporting bias. METHODS: A modified Delphi process was performed though involvement of ANP content experts...

BACKGROUND: Total pancreatectomy with islet autotransplant (TPIAT) can improve quality of life for individuals with pancreatitis but creates health risks including diabetes, exocrine insufficiency, altered intestinal anatomy and function, and asplenia. METHODS: We studied survival and causes of death for 693 patients who underwent TPIAT between 2001 and 2020, using the National Death Index with medical records to ascertain survival after TPIAT, causes of mortality, and risk factors for death...

OBJECTIVES: We aimed to estimate the incidence of new-onset diabetes (NOD) and identify risk factors for NOD in patients with necrotizing pancreatitis (NP). METHODS: Necrotizing pancreatitis patients were reviewed for NOD, diagnosed >90 days after acute pancreatitis. Baseline demographics, comorbidities, clinical outcomes, computed tomography (CT) characteristics of necrotic collections, and CT-derived abdominal fat measurements were analyzed to identify predictors for NOD...

Liposarcoma is the most common type of soft-tissue sarcoma and typically occurs in the extremities or retroperitoneum. Primary liposarcoma of the pancreas is exceedingly rare, with only 10 cases reported since 1979. We present a patient who was incidentally discovered to have a pancreatic mass on imaging, which was ultimately diagnosed as dedifferentiated pancreatic liposarcoma. We review the clinical and histologic features of pancreatic liposarcoma in this case and in the 10 previously reported cases to increase awareness and knowledge of this rare disease...

BACKGROUND: Although diabetes after total pancreatectomy and islet autotransplantation (TP-IAT) is one of the biggest concerns for TP-IAT recipients and physicians, reliable prediction of post-TP-IAT glycemic control remains unestablished. This study was conducted to identify early predictors of insulin independence and goal glycemic control by hemoglobin A1c (HbA1c) ≤ 6.5% after TP-IAT. METHODS: In this single-center, retrospective study, patients who underwent TP-IAT (n = 227) were reviewed for simple metabolic markers or surrogate indices of β-cell function obtained 3 mo after TP-IAT as part of standard clinical testing...

BACKGROUND: There have been no studies that have systematically evaluated whether previously validated patient and procedural risk factors for PEP remain significant in patients receiving rectal indomethacin. METHODS: Data from a randomized controlled trial (RCT) of high-risk patients undergoing ERCP who received rectal indomethacin with or without topical epinephrine was evaluated. PEP was defined using the consensus criteria definition. Pancreatic stenting was excluded to avoid confounding results with the role of epinephrine spray...

BACKGROUND AND AIMS: Total pancreatectomy with islet autotransplantation (TPIAT) can relieve pain for individuals with acute recurrent or chronic pancreatitis. However, TPIAT may increase the risk of poor nutritional status with complete exocrine pancreatic insufficiency, partial duodenectomy, and intestinal reconstruction. Our study's objective was to evaluate nutritional status, anthropometrics, and vitamin levels before and after TPIAT. METHODS: The multicenter Prospective Observational Study of TPIAT (POST) collects measures including vitamins A, D, and E levels, pancreatic enzyme dose, and multivitamin (MVI) administration before and 1-year after TPIAT...

In a subset of patients with acute necrotizing pancreatitis, segmental necrosis affecting the main pancreatic duct may result in a discontinuity between the left-sided pancreas and the duodenum. Such an interruption in the setting of a viable upstream portion of the gland can give rise to the disconnected pancreatic duct syndrome (DPDS). By maintaining its secretory function, the disconnected segment may lead to persistent external pancreatic fistulae, recurrent pancreatic fluid collections, and/or obstructive recurrent acute or chronic pancreatitis of the isolated parenchyma...

BACKGROUND AND AIMS: The clinical course of necrotizing pancreatitis (NP) is variable and unpredictable, with some patients managed conservatively, but a significant proportion become symptomatic and needing intervention for drainage and/or necrosectomy. The aim of this study was to identify patients based on baseline clinical and imaging metrics who will likely need intervention and therefore closer follow-up. METHODS: All NP patients managed in our institution between 2010 and 2019 were identified from a prospective database and those who did not undergo intervention during initial hospitalization were followed longitudinally post discharge until clinical and imaging resolution of necrosis...

BACKGROUNDS/OBJECTIVES: Patients with chronic pancreatitis may develop pancreatic duct stones that can obstruct outflow leading to ductal hypertension and pain. Both endoscopic retrograde pancreatography (ERP) with per-oral pancreatoscopy (POP) and intraductal lithotripsy and extracorporeal shock wave lithotripsy (ESWL) are feasible options to attempt ductal stone clearance. This study aims to compare POP-guided lithotripsy with ESWL in the management of refractory symptomatic main pancreatic duct stones...

Acute pancreatitis (AP) is a disease characterized by an acute inflammatory phase followed by a convalescent phase. Diabetes mellitus (DM) was historically felt to be a transient phenomenon related to acute inflammation; however, it is increasingly recognized as an important late and chronic complication. There are several challenges that have prevented precisely determining the incidence rate of DM after AP and understanding the underlying mechanisms. The DREAM (Diabetes RElated to Acute Pancreatitis and its Mechanisms) Study is a prospective cohort study designed to address these and other knowledge gaps to provide the evidence needed to screen for, prevent, and treat DM after AP...

OBJECTIVES: Chronic pancreatitis (CP) is characterized by abdominal pain, recurrent hospitalizations, frequent exposure to antibiotics, nutritional deficiencies, and chronic opioid use. Data describing the gut microbial community structure of patients with CP is limited. We aimed to compare gut microbiota of a group of patients with severe CP being considered for total pancreatectomy with islet autotransplantation (TPIAT) with those of healthy controls and to associate these differences with severity of clinical symptoms...

Extra-nodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) is uncommon and difficult to diagnose due to varied clinical presentations and endoscopic appearances masquerading as other pathology. Rarely, it has been associated with acute upper gastrointestinal (GI) bleeding. We report on a 60-year-old male who presented with an acute upper GI bleed and endoscopic findings suggestive of isolated gastric varices (GV), ultimately determined to be MALT lymphoma. Complete remission was achieved with radiation therapy, with no recurrence at a 12-month follow-up...

OBJECTIVE: To determine if islet autotransplantation (IAT) independently improves quality of life in patients after total pancreatectomy and islet auto transplantation (TP-IAT). SUMMARY BACKGROUND DATA: TP-IAT is increasingly being used for intractable chronic pancreatitis. However, the impact of IAT on long-term islet function and QoL is unclear. METHODS: TP-IAT patients at our center >1 year after TP-IAT with ≥1 Short Form-36 QoL measure were included...
