An Update on Pediatric Pancreatitis

Clinical Utility of Definitive Diagnostic Tests for Choledocholithiasis in Pediatric Patients with Mild Gallstone Pancreatitis

BACKGROUND

Gallstone pancreatitis was historically considered a risk factor for choledocholithiasis (CD). However, recent studies of adult patients evidenced a weak association between gallstone pancreatitis and CD. The aim of this study was to analyze this association in pediatric patients.

METHODS

We conducted a retrospective study on patients with mild gallstone pancreatitis who underwent any definitive testing for CD (MRCP, ERCP, IOC), managed between March 2010 and September 2022. Patients were classified according to the presence or absence of risk factors for CD (total bilirubin ≥2 mg/dl; common bile duct >6 mm on ultrasound; and/or CD on ultrasound). We evaluated the diagnosis of CD on definitive testing in both groups and analyzed the predictive capacity of the presence of risk factors.

RESULTS

Eighty-four patients were included in the final analysis. Seventy-nine percent were females. The median age was 13 (4-17) years. Forty-seven (55.9%) patients had one or more risk factors. The definitive testing confirmed 13 (15.5%) cases of CD, 12 (25.5%) in the group of patients with risk factors and 1 (2.7%) in those without risk factors. The sensitivity, specificity, positive predictive value and negative predictive value of the presence of associated risk factors were 92.3, 50.7, 25.5 and 97.3%, respectively.

CONCLUSION

Pediatric patients with gallstone pancreatitis without associated risk factors have a very low incidence of CD. In these patients we suggest performing a laparoscopic cholecystectomy without intraoperative cholangiography or any other definitive test for CD.

A Retrospective Review of Children followed up with the Diagnosis of Acute Pancreatitis

BACKGROUND

Acute pancreatitis (AP) is an inflammatory disease of the pancreas, the frequency of which increases in childhood.

AIM

To investigate the demographic, etiological, clinical, laboratory, and radiological characteristics of children followed up with the diagnosis of AP. The study also included genetic studies of recurrent cases.

MATERIALS AND METHODS

This retrospective cohort study included pediatric patients <18 years of age with AP who were followed up with recurrent pancreatitis in the Pediatrics Department of a University Hospital between January 2010 and April 2021. Patients who met at least 2 of the 3 criteria defined by the International Pediatric Pancreatitis Study Group (INSPPIRE) were accepted as AP. Demographic, etiological, and clinical data of the patients, developing complications, pathological evaluation of the samples, and genetic analysis results were obtained from the patient files. The obtained data were statistically analyzed using the SPSS version 26.0 program. Descriptive statistics of the data were expressed as mean ± standard deviation, median, minimum and maximum values, number (n), and percentage (%). Kolmogorov-Smirnov test, Mann Whitney U test, Chi-square test and Fischer test were used.

RESULTS

Fifty-four (50%) female and 54 (50%) male patients with a mean age of 9.96 ± 4.8 years who met the study criteria were included in the study. In the follow-up, it was reported that acute recurrent pancreatitis developed in 23 (21%) patients and chronic pancreatitis developed in 8 (7%) patients. The most common complaints were abdominal pain (94.4%), and vomiting (60.2%), followed by malnutrition (36.1%), nausea (17.6%), diarrhea (13%), and fever (13%). Etiology could not be determined in 19.4% of the patients. It was noted that the genetic predisposition of the patients played a role in the development of recurrent and chronic pancreatitis. Amylase, lipase, and CRP values, which are among the laboratory parameters showing the severity and prognosis of AP, were found to be significant.

CONCLUSIONS

Sociocultural and demographic data of the patients should also be taken into account. Gene sequences that cause to genetic predisposition should be determined in recurrent and chronic pancreatitis cases. Acute pancreatitis should be considered in the differential diagnosis of patients with frequent abdominal pain and vomiting.

Etiology, case fatality, recurrence, and severity in pediatric acute pancreatitis: a meta-analysis of 48 studies

For children, there are very few published reviews focusing on severe acute pancreatitis (AP). PubMed, EMBASE, Web of Science, Scopus, Chinese National Knowledge Infrastructure (CNKI), Wanfang data, EBSCO, and Cochrane Library were searched from inception until March 2020. Meta-regression analyses were used to estimate the etiology, case fatality, recurrence, and severity of pediatric AP in different regions (North America, Asia, South America, Europe, and Oceania). Pooled data from 47 papers (48 studies) found that main causes of pediatric AP were gallstones in Asia; trauma in Oceania; and idiopathic in Europe, North America, and South America. The case-fatality rate (CFR) of pediatric AP is 4.7% (North America), 6.2% (Europe), 2.4% (Asia), 3.1% (South America), and 7.4% (Oceania). The incidence rates of recurrent acute pancreatitis (RAP) in children who have had an episode of acute pancreatitis in North American, Asia, and Europe were 15.3, 13.1, and 13.8%, respectively. The incidence of severe acute pancreatitis (SAP) in different regions was 30.3% (Oceania), 29.2% (South America), 20.8% (Europe), 15.8% (Asia), and 13.7% (North America). It suggests that physicians should notice the etiology of pediatric AP for the initial assessment, diagnosis, prediction of relapse, and appropriate treatment at a later stage. IMPACT: It indicates the etiology of pediatric acute pancreatitis for the initial assessment, diagnosis, and prediction of relapse. Main causes of pediatric AP were gallstones in Asia; trauma in Oceania; and idiopathic in Europe, North America, and South America. The case-fatality rate of pediatric AP is diverse worldwide. It suggests that physicians noticed the etiology of pediatric AP for the initial assessment, diagnosis, prediction of relapse, and appropriate treatment at a later stage.

Acute Pancreatitis in Children: The Clinical Profile at a Tertiary Hospital

Objectives The clinical course and progression of acute pancreatitis are poorly understood to date, necessitating more studies of clinical profiles during the disease. Moreover, understanding the etiologies and clinical presentations of acute pancreatitis (AP) in children can contribute to early diagnosis and, hence, earlier interventions. Therefore, this article aims to study the clinical profiles of children with acute pancreatitis (AP) in relation to complications and other variables. Study design We retrospectively studied 56 patients who presented with AP to the pediatric department in Salmaniya Medical Complex between January 2006 and December 2017. Cases of chronic pancreatitis and ages above 12 years were excluded. The data concerned demographics, etiology, clinical data, hospital course, and outcomes. Results The study included 56 patients aged a mean of 8.46 years (male:female - 33:23). The average hospital stay was 7.68 days. Patients received parenteral feeds a mean of 2.77 days. All patients had an ultrasound, nine required CT scans (16.1%), and five MRIs (8.9%). There were 18 local complications (32.1%): pseudocysts (n=3, 5.36%), cholangitis (n=2, 3.6%), and edema (n=13, 23.2%). There were 23 intensive care unit (ICU) admissions (41.1%). No mortalities occurred but there were six recurrences (10.7%). Symptoms of abdominal pain, vomiting, fever, and nausea occurred in 100%, 57.1%, 35.7%, and 23.2% of patients, respectively. Etiologies were 41.1% biliary, 23.2% idiopathic, 19.6% traumatic, and 8.93% drug-induced. Leukocytes were elevated in 20 patients (35.7%), c-reactive protein (CRP) in five (8.93%), serum amylase in 45 (80.4%), and urinary amylase in all 56 patients (100%). Conclusion Most pediatric AP cases were attributed to biliary causes followed by trauma. Age was significantly correlated with complication rates (P=0.013). Abdominal pain was a more common symptom than vomiting. Leukocytosis was associated with ICU admissions. There was no significant relation between c-reactive protein, serum amylase, or urinary amylase, and complications or ICU admissions. Pediatric AP was self-limiting and there were no fatalities.

Pulmonary Manifestations of Gastrointestinal, Pancreatic, and Liver Diseases in Children

Pulmonary manifestations of gastrointestinal (GI) diseases are often subtle, and underlying disease may precede overt symptoms. A high index of suspicion and a low threshold for consultation with a pediatric pulmonologist is warranted in common GI conditions. This article outlines the pulmonary manifestations of different GI, pancreatic, and liver diseases in children, including gastroesophageal reflux disease, inflammatory bowel disease, pancreatitis, alpha1-antitrypsin deficiency, nonalcoholic fatty liver disease, and complications of chronic liver disease (hepatopulmonary syndrome and portopulmonary hypertension).

Pancreatitis in multiple acyl CoA dehydrogenase deficiency: An underdiagnosed complication

BACKGROUND

Multiple acyl-CoA dehydrogenase (MADD) deficiency represents a rare fatty acid oxidation disorder where sporadic reports of pancreatitis already exist. Here, we report three cases of MADD with pancreatic involvement raising questions whether this represents an incidental finding or it is related to the pathophysiology of MADD.

METHODS

We have retrospectively studied the clinical, biochemical and radiologic data of patients with MADD diagnosed in our department over the last 20 years to identify patients with pancreatic involvement.

RESULTS

Three out of 17 patients had pancreatic involvement. All three patients were diagnosed with MADD in the neonatal period (two-third symptomatic-riboflavin nonresponsive, one-third asymptomatic via newborn screening-riboflavin responsive). Age at presentation of pancreatitis ranged from 20 months to 11 years. Presentations included a single episode of acute pancreatitis in the first patient, chronic necrotizing pancreatitis in the second patient, while the third patient was diagnosed with chronic pancreatitis (CP) incidentally through ultrasonography. All patients had inflammation features on either abdominal computed tomography or ultrasound. Pancreatic enzymes were elevated in two patients. Management of pancreatitis was done conservatively while the patient with necrotic CP required subtotal pancreatectomy.

DISCUSSION

Our data suggest that pancreatitis might be more common in patients with MADD than previously reported, requiring a high index of suspicion in patients with acute metabolic decompensation or nonspecific abdominal symptoms. We hypothesize that the underlying mechanism of pancreatitis in MADD is similar to that in mitochondrial disorders, both resulting from disordered energy metabolism and oxidative phosphorylation.

Burkitt Lymphoma Presenting as Acute Pancreatitis: Report of 3 Cases and Review of the Literature

Acute pancreatitis is a rare presentation in Burkitt lymphoma (BL) and may lead to delayed medical or unnecessary surgical treatment. Three cases of BL presenting as acute pancreatitis in the authors' institutions were described. Similar cases reported in the medical literature were collected and described along with the authors' cases. There were 12 cases described in the medical literature and hence a total of 15 cases of BL presenting as acute pancreatitis. Fourteen cases were the first diagnosis, and the other presented at lymphoma relapse. Twelve cases occurred in children under 15 years. Twelve patients had extrapancreatic disease. Three children were treated with surgery before diagnosis. Two patients died. Six of the remaining had adequate follow-up and were surviving in remission 8 months to 16 years after diagnosis. Lymphoma should be included in the differential diagnosis of acute pancreatitis in children. Acute pancreatitis in combination with malignant infiltration on imaging is highly suggestive of BL, especially in the jaundiced child.

Acute pancreatitis in children: Updates in epidemiology, diagnosis and management

Acute pancreatitis (AP), manifesting as acute onset of abdominal pain, vomiting, and nausea, is increasingly being recognized in children secondary to increased awareness, more identifiable etiologies as well as advances in diagnostic capabilities, like imaging. Despite this increased awareness and ability for more frequent diagnoses, the natural history of AP remains poorly understood leading to gaps in approach and management, especially in children. Coupled with poor epidemiologic and management awareness, there remains a lack of understanding of the long term implications of severe acute pancreatitis (SAP). Hence, the role of the primary care clinician in the early diagnosis, and management, remains critical and may affect the need for consultation with pediatric sub-specialists like gastroenterologists. This review provides guidelines regarding epidemiology, diagnosis, and management strategies to address some of these gaps.

Pancreatitis in pre-adolescent children: a 10 year experience in the pediatric emergency department

Background

The diagnosis of pediatric pancreatitis has been increasing over the last 15 years but the etiology of this is uncertain. The population of pre-adolescent patients with pancreatitis in the emergency department has not been specifically described. Our objective was to determine the characteristics of these patients to illuminate this population and disease in order to better identify them and avoid a delay in diagnosis and treatment.

Methods

This was a retrospective descriptive study of consecutive pediatric patients under the age of 13 years between 2006 and 2016 who presented to our pediatric emergency department with a diagnosis of atraumatic pancreatitis. Patient characteristics, lab and imaging results, identified etiology of pancreatitis, and recurrence rates were recorded and evaluated.

Results

There were 139 visits, of which 85 were for a first episode of acute pancreatitis, and 54 were patients with an episode of recurrent pancreatitis. The median age for all visits was 8 years (IQ range 5–11). Of the acute cases, 26% had uncertain or undetermined etiologies of which half were thought to likely be viral related; 20% had systemic inflammatory or autoimmune diseases; 19% were associated with medications, with the most common being valproic acid; 16% were cholelithiasis-related; and 15% were found to have a genetic, congenital or structural etiology. No patients had elevated triglycerides. Those with cholelithiasis and genetic or structural defects were found to have a higher recurrence rate than those with other etiologies. There were only four patients diagnosed with chronic pancreatitis.

Conclusions

The etiology of pancreatitis in pre-adolescent children has a different distribution than in adolescents and adults, with gallstone disease less frequent and concurrent contributing illness more common. Patients on pancreatitis-causing medications or with known genetic risk or structural pancreatic problems should be tested for pancreatitis if presenting with concerning symptoms. Hypertriglyceridemia and chronic pancreatitis with evidence of pancreatic exocrine insufficiency is uncommon in this population.

Nutrition Interventions in Pediatric Pancreatitis: Guidelines We Can Trust

OBJECTIVE

Despite the fact that pediatric pancreatitis is an uncommon disease, its prevalence has increased in recent years. Nevertheless, until 4 years ago, the lack of nutritional guidelines for pediatric pancreatitis was evident, with all recommendations being based on clinical practice guidelines (CPGs) for adults. The aim of the present study was to review and critically appraise guidelines for the medical nutrition therapy (MNT) of pediatric pancreatitis.

METHODS

A comprehensive search was performed in electronic databases (PubMed, Scopus, National Institute for Health and Care Excellence), the International Guidelines Network, BMJ best practice, and the Scottish Intercollegiate Guidelines Network to identify CPGs on the MNT of pediatric pancreatitis. The validated AGREE II tool was used for guidelines appraisal by a team of 3 independent multidisciplinary reviewers.

RESULTS

A total of 4 CPGs were retrieved with pediatric pancreatitis MNT information. Out of the 4 advising bodies in total, the joint society paper published by the ESPGHAN/NASPGHAN received the highest score in almost all domains, whereas the Belgian consensus obtained the lowest score in all domains but stakeholder involvement, and was not recommended by 2 out of 3 reviewers.

CONCLUSIONS

Pediatric pancreatitis guidelines appear heterogenous in quality, rigour, and transparency. Our study points out existing gaps and biases in the CPGs, and delineates the need for improving the domains identified as being of low-quality.
