Chronic pancreatitis calcification risk factors

Chronic pancreatitis (CP) is an irreversible and progressive inflammation of the pancreas that can involve both pancreatic parenchyma and the pancreatic duct. CP results in morphological changes in the gland in the form of fibrosis and calcification along with functional impairment in the form of exocrine and endocrine insufficiency. Studies on the natural history of CP reveal the irreversibility of the condition and the resultant plethora of complications, of which pancreatic adenocarcinoma is the most dreaded one...

BACKGROUND: Groove pancreatitis is a focal form of chronic pancreatitis affecting the area of the paraduodenal groove. The aim of this systematic review was to assess the clinical presentation, diagnosis and treatment of patients with groove pancreatitis. METHODS: Medical literature databases (Embase, Medline via PubMed and Cochrane Central Register of Controlled Trials) were systematically searched for data recorded between 1 January 1990 and 31 August 2022 regarding patient characteristics, diagnosis, surgical treatment and outcomes...

In patients with chronic pancreatitis, pancreatic calcification is a risk factor for diabetes development, poor islet yield, and metabolic outcomes after total pancreatectomy with islet autotransplantation (TPIAT). We investigated whether calcification pattern based on computed tomography is associated with outcomes using our database of 200 consecutive TPIAT procedures. Three groups were compared: noncalcification (NC); focal calcification (FC), limited to the pancreas head, body, or tail; and diffuse calcification (DC), with calcification in >2 sections...

BACKGROUND: Paraduodenal pancreatitis (PP) represents a diagnostic challenge, especially in non-referral centers, given its potential imaging overlap with pancreatic cancer. There are two main histological variants of PP, the cystic and the solid, with slightly different imaging appearances. Moreover, imaging findings in PP may change over time because of disease progression and/or as an effect of its risk factors exposition, namely alcohol intake and smoking. AIM: To describe multimodality imaging findings in patients affected by PP to help clinicians in the differential diagnosis with pancreatic cancer...

INTRODUCTION: A dilatation of the main pancreatic duct (MPD) is mainly due to obstructive causes (pancreatic tumor, chronic pancreatitis) or intraductal papillary mucinous neoplasm (IPMN). This study aims to assess the risk of pre-malignancy or malignancy in case of MPD dilatation with no visible mass nor obstructive calcification on computed tomography scan (CT-scan) in a population operated for it. PATIENTS AND METHODS: All patients operated on from November 2015 to December 2019 in our center for a significant dilatation of the MPD without visible obstructive cause on CT-scan were included...

We aimed to present the incidence and risk factors for pancreatic cancer in a multicenter retrospective cohort of patients with chronic pancreatitis (CP). Patients with ICD-10 codes for CP (K86.0, K86.1) who underwent abdominal CT or MRI between January 2010 and December 2021 in seven academic hospitals were analyzed. After exclusions, we identified 727 patients with definite CP with a median follow-up of 3.6 years (range 1.0‒12.9). During 3290 person-years of observation, pancreatic cancers were diagnosed in 16 patients (2...

BACKGROUND AND AIMS: A significant factor contributing to poor survival in pancreatic cancer is the often late stage at diagnosis. We sought to develop and validate a risk prediction model to facilitate the distinction between chronic pancreatitis-related vs potential early pancreatic ductal adenocarcinoma (PDAC)-associated changes on pancreatic imaging. METHODS: In this retrospective cohort study, patients aged 18-84 years whose abdominal computed tomography/magnetic resonance imaging reports indicated duct dilatation, atrophy, calcification, cyst, or pseudocyst between January 2008 and November 2019 were identified...

OBJECTIVE: Diabetes that arises from chronic pancreatitis (CP) is associated with increased morbidity and mortality. Methods to predict which patients with CP are at greatest risk for diabetes are urgently needed. We aimed to examine independent risk factors for diabetes in a large cohort of patients with CP. RESEARCH DESIGN AND METHODS: This cross-sectional study comprised 645 individuals with CP enrolled in the PROCEED study, of whom 276 had diabetes. We conducted univariable and multivariable regression analyses of potential risk factors for diabetes...

OBJECTIVES: Pancreatic calcifications (PC) are considered specific for chronic pancreatitis (CP), but PC may also be present in non-CP diseases. The aims are to understand the pattern of calcifications in different diseases and to determine they were related to malignant diseases. METHODS: A retrospective study was performed including patients with PC or CP undergoing surgery in the Department of General Surgery of Ruijin Hospital from January 2003 to June 2018...

Up to 9% of children with acute recurrent pancreatitis (ARP) or chronic pancreatitis have pancreatogenic diabetes mellitus (DM), and this risk likely increases as they age into adulthood. Risk factors for pancreatogenic DM in children vary depending on the clinical cohort but may include pancreatic atrophy, exocrine insufficiency, pancreatic calcifications, obesity/metabolic syndrome features, or autoimmune diseases. Knowledge regarding disease pathology is extrapolated nearly entirely from studies in adults...

INTRODUCTION: Pancreatic cytosteatonecrosis is a rare condition associated with various pancreatic diseases such as acute or chronic pancreatitis and pancreatic cancer. We report a case of pancreatic cytosteatonecrosis discovered at autopsy. OBSERVATION: This is a young man, 29 years old, alcoholic, non-smoker, who consulted for abdominal pain, vomiting, fever (38°). Renal ultrasound showed signs of acute renal failure, with severe anemia at 6g/dl and hyperleukocytosis...

PURPOSE OF REVIEW: The purpose of this review is to delineate risk factors for the development of diabetes in patients with chronic pancreatitis. The natural history including progression to diabetes and complications that develop once diabetes occurs in chronic pancreatitis is also reviewed. RECENT FINDINGS: Studies have found that predictors of diabetes in chronic pancreatitis include both risk factors for type 2 diabetes (e.g., obesity, genetic variants) as well as pancreas-specific factors (e...

OBJECTIVES: The relation between aetiology and structural changes of the pancreas in patients with chronic pancreatitis (CP) is not fully understood. Earlier studies are limited by focusing on selected factors in studies of limited sample size. We aimed to use a large dataset to explore associations between aetiology and pancreatic morphology in CP. METHODS: Subjects with definite or probable CP according to the M-ANNHEIM diagnostic criteria were included in this multicentre cross-sectional observational study and assessed using a standardized and validated CP imaging system...

Chronic pancreatitis is a complex chronic inflammatory condition that results in pancreas fibrosis and calcification with subsequent exocrine and endocrine insufficiency. Alcohol and nicotine are the most prevalent risk factors, however, recent studies have increasingly discovered genetic associations that increase the risk to develop chronic pancreatitis. Here, we discuss different etiologies of the disease including autoimmune pancreatitis, and present evidence-based diagnostic and therapeutic approaches...

INTRODUCTION: Chronic pancreatitis are mostly linked to alcoholic consumption or biliary lithiasis; and Primary hyperthyroidism (PHPT) is still a very rare association and the exact physiopathology is yet to be fully unveiled to the human knowledge. We present the first case report of a calcific pancreatitis associated with not only PHPT but a multiple endocrine neoplasia (MEN) type 1. CASE PRESENTATION: We report the case of a 52 years old woman suffering from mellitus diabetes consulting the emergency rooms for acute pancreatitis with hyperlipasemia and hypercalcemia whom final imaging discovered a pituitary gland adenoma, a left surrenal adenoma, and a parathyroid adenoma, and for the pancreas it reveiled an acute mild pancreatitis with a background of calcifications, no gallstones, no bone or renal abnormalities; and the parathyroidectomy was performed following the minimally invasive selective technique...

Endocrine insufficiency is a common and frequent complication of chronic pancreatitis. Identifying the role of pancreatic damage in the development of diabetes is important for early identification and appropriate management. METHODS: All consecutive CP patients between January 2019 and May 2020 were retrospectively studied. Relevant statistical tests were performed. A two sided p value < 0.05 was considered statistically significant. RESULTS: Total 587 chronic pancreatitis patients were included of which 118 (20...

STUDY AIM: To develop and apply a natural language processing algorithm for characterization of patients diagnosed with chronic pancreatitis in a diverse integrated U.S. healthcare system. METHODS: Retrospective cohort study including patients initially diagnosed with chronic pancreatitis (CP) within a regional integrated healthcare system between January 1, 2006 and December 31, 2015. Imaging reports from these patients were extracted from the electronic medical record system and split into training, validation and implementation datasets...

INTRODUCTION: Vascular complications such as venous thrombosis (VT) and pseudoaneurysm are not uncommon in patients with chronic pancreatitis (CP). The aim of this study to was to evaluate the prevalence and risk factors for vascular complications in patients with CP. METHODS: A retrospective analysis of a prospectively maintained database of patients with CP presenting from January 2002 to August 2019 was performed. Venous thrombosis and pseudoaneurysm were identified using radiological imaging, and their risk factors were identified using multivariate Cox-proportional hazards...

BACKGROUND/OBJECTIVES: Patients with autoimmune pancreatitis (AIP) sometimes progress to chronic pancreatitis (CP). We evaluated the ability of corticosteroids to prevent the progression to CP. METHODS: We defined patients with definitive findings of CP (stones in the main pancreatic duct [MPD] or multiple pancreatic calcifications) as having severe calcification (SC). A total of 145 AIP patients were enrolled. We measured the duration between AIP diagnosis and SC development and retrospectively compared the time to SC development between patients with and without steroids...

OBJECTIVES: We lack reliable methods for identifying patients with chronic pancreatitis (CP) at increased risk for pancreatic cancer. We aimed to identify radiographic parameters associated with pancreatic cancer in this population. METHODS: We conducted a retrospective cohort study of patients with suspected CP within an integrated healthcare system in Southern California in 2006-2015. Patients were identified by a diagnostic code and confirmed by imaging findings (parenchymal calcification, ductal stones, glandular atrophy, pseudocyst, main duct dilatation, duct irregularity, abnormal side branch, or stricture) defined by the natural language processing of radiographic reports...
