Acute pancreatitis in children

Acute Pancreatitis and Acute Recurrent Pancreatitis in Children: Imaging Findings and Outcomes

OBJECTIVE

The prevalence of acute pancreatitis and acute recurrent pancreatitis in children has increased over the years, and there are limited data about imaging findings. This study aimed to reveal the imaging findings of acute pancreatitis and acute recurrent pancreatitis in children at a tertiary care hospital.

MATERIALS AND METHODS

The patients with acute pancreatitis and acute recurrent pancreatitis diagnosed between January 2007 and December 2018 were included. Demographic and clinical features, follow-up period, and interventions were noted. Imaging features were evaluated for pancreatic enlargement, peripancreatic fluid, and biliary ducts for initial examination and pancreas parenchymal necrosis, peripancreatic collection, walled-off necrosis, pseudocyst, parenchymal atrophy, and biliary ductal dilatation for follow-up.

RESULTS

The study included 74 patients with a mean age of 9 ± 4.9 years. The most common causes of acute pancreatitis and acute recurrent pancreatitis were biliary tract anomalies (n = 21), biliary ductal stones (n = 9), and cystic fibrosis (n = 8). Findings consistent with acute pancreatitis were determined by ultrasound in 40.5% (n = 30/74), whereas by magnetic resonance imaging in 60% (n = 39/65). Forty-one percent of the patients (n = 16) with positive magnetic resonance imaging findings did not show any findings on ultrasound. Acute recurrent pancreatitis was seen in 32 patients (43.2%). Follow-up imaging was performed in 55 patients (74.3%) between 2 months and 11 years. At follow-up, 8 patients had peripancreatic collections (6 walled-off necrosis and 2 pseudocysts).

CONCLUSION

Recognizing the imaging findings of acute pancreatitis and its complications is crucial. Magnetic resonance imaging should be preferred as a second option following ultrasound, with the advantages of biliary ductal system delineation and better characterization of complications.

Acute Pancreatitis and Recurrent Acute Pancreatitis in Children: A 10-Year Retrospective Study

Aim

To compare the clinical characteristics of acute pancreatitis (AP) and recurrent acute pancreatitis (ARP) in children.

Method

From January 2011 to January 2021, a total of 275 pediatric patients with AP admitted to a tertiary teaching hospital were enrolled.

Results

The median age of 275 children was 12.0 years. Among them, 55 cases were ARP. The leading causes of pediatric pancreatitis were biliary tract and virus infection. The percent of male in the AP group was higher than that in the ARP group. Viral infection in the AP group were higher than that in the ARP group, but anatomical abnormalities were lower than those in the ARP group. The incidence of pancreatic pseudocysts in the ARP group was higher than that in the AP group. The median interval time from AP to ARP was 3.0 months.

Conclusion

The main causes of pediatric pancreatitis were biliary tract and virus infection in the study. AP caused by virus infection seems to be less likely to develop into ARP. Female and anatomical abnormality are risks of ARP. Children with ARP are more likely to be complicated with pancreatic pseudocyst. There was no difference in ICU admission or mortality between AP and ARP.

Risk Factors, Clinical Features, and Outcomes of Acute Pancreatitis in Children in Endemic Zone of Ascariasis in Eastern Bihar: A Hospital-Based Study

Objective

This study aims to describe the etiology, clinical features, and outcomes of acute pancreatitis (AP) in children in an endemic area of hepatobiliary ascariasis.

Methods

This retrospective observational study included acute pancreatitis (AP) patients in the age group of 2-15 years from January 2019 to January 2022. Demographic profile, risk factors, clinical features, laboratory imaging, and outcome data were collected and analyzed.

Results

A total of 40 patients comprising of 21 males (52.5%) and 19 females (47.5%) were included. The median age of the diagnosis of AP was 8.3 years (range: 4-14 years). Biliary ascariasis was the most frequent etiology of AP (n=18, 45%), followed by gallbladder (GB) stone (n=6, 12%), trauma (n=1, 2.5%), hepatitis (n=1, 2.5%), valproate drug (n=1, 2.5%), and GB sludge (n=1, 2.5%). In clinical features, all cases had pain in the abdomen (n=40, 100%), followed by fever (n=9, 22.5%), nausea/vomiting (n=33, 82.5%), jaundice (n=2, 5%), and anemia (n=2, 5%). Three (7.5%) patients developed complications such as shock, pseudocyst, and necrotizing pancreatitis, respectively. The average median hospital stay was nine days (range: 4-20 days). No mortality occurred in our study.

Conclusions

This study revealed a high prevalence (12-13 cases/year) of AP in children in this area. Biliary ascariasis (45%) emerged as the commonest risk factor. Most of the cases suffered from mild AP (92%) and so recovered completely without any complication.

Magnetic resonance imaging glossary of findings of pediatric pancreatitis and the revised Atlanta classification

While still uncommon, the incidence of acute pancreatitis in children has been increasing over the last two decades. The Atlanta classification for acute pancreatitis, developed for adults, stratifies cases of acute pancreatitis based on imaging and clinical criteria. This classification scheme allows for standardized use of terminology to facilitate treatment and prognostication. Although US and CT should be used in critical or unstable patients, MRI is an ideal imaging modality in pediatric patients with acute pancreatitis because of its ability to characterize tissue without ionizing radiation. We review MRI examples specific to Atlanta classification terminology in pediatric patients. Chronic pancreatitis has also been increasingly diagnosed in children, and imaging plays a key role in the diagnosis and management of this insidious disease. MRI with magnetic resonance cholangiopancreatography is the optimal modality for assessing the pancreas in a child with known or suspected chronic pancreatitis because it provides tissue characterization and high-contrast imaging of the pancreatic duct without the use of invasive instrumentation or ionizing radiation. We also review and demonstrate accepted MRI findings of chronic pancreatitis.

Acute Pancreatitis in Jordanian Children: A Single Center Experience

BACKGROUND

There is still much to understand and discover regarding pediatric pancreatitis. The etiology, clinical presentation, and prognosis of pancreatitis differs considerably between young children and adults. The incidence of pancreatitis has been increasing; it is no longer as rare in children as previously thought and could cause significant morbidity and mortality when severe.

METHODS

In this retrospective study conducted at a tertiary care hospital in Jordan, we present a cohort of children with 64 episodes of acute pancreatitis.

RESULTS

While abdominal pain was the most common presenting complaint in our cohort (97%), the classical features of radiation to the back and relief by the forward-lean position were observed in only one-third of our patients. Compared to serum amylase, serum lipase had a higher sensitivity for detecting pancreatitis (98 vs. 67%). Abdominal ultrasound is a non-invasive, widely available imaging modality; when performed, it revealed an enlarged pancreas in almost 60% of the patients. However, abdominal ultrasonography is often limited by the presence of excessive bowel gas. Anatomical abnormalities were the most common etiologies of pancreatitis (29%), followed by idiopathic pancreatitis (21%), and biliary causes (21%).

CONCLUSION

In our cohort, serum lipase was a better diagnostic tool compared to serum amylase. Congenital biliary-pancreatic abnormalities were the most common causes of acute pancreatitis in our cohort. Almost half of these patients developed recurrent acute pancreatitis. The prevalence of pancreatic pseudocysts was 16.7%, and nearly half of them required an intervention.

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.

Clinical characteristics of acute pancreatitis in children: a single-center experience in Western China

BACKGROUND

The diagnosis of pediatric pancreatitis has been increasing over the last 20 years. We aimed to compare the clinical characteristics for pediatric acute pancreatitis (AP) with adult AP, and investigate the risk factor for acute recurrent pancreatitis (ARP) in children.

METHOD

From June 2013 to June 2019, a total of 130 pediatric patients with AP at the inpatient database were enrolled. Univariate analysis and multivariate Cox regression analysis were performed to identify the risk factors for ARP in children.

RESULT

Major etiologic factors in 130 patients were biliary (31.5%), idiopathic (28.5%). The etiology of pancreatitis in children was markedly different from that in adults (p < 0.001). Compared with the adult patients, the pediatric patients had significantly lower severity (p = 0.018) and occurrence rate of pancreatic necrosis (p = 0.041), SIRS (p = 0.021), acute peripancreatic fluid collection (p = 0.014). Univariate and Multivariate Cox regression analysis showed that female (p = 0.020; OR 3.821; 95% CI 1.231-11.861), hypertriglyceridemia (p = 0.045; OR 3.111; 95% CI 1.024-9.447), pancreatic necrosis (p = 0.023; OR 5.768; 95% CI 1.278-26.034) were the independent risk factors of ARP. Hypertriglyceridemia AP had the highest risk of recurrence compared to other etiology (p = 0.035).

CONCLUSION

Biliary and idiopathic disease were the major etiologies of AP in children. Children have simpler conditions than adults. Female, hypertriglyceridemia, and pancreatic necrosis were associated with the onset of ARP.

Posaconazole-Induced Acute Pancreatitis: A Rare Side Effect in a Child with Chronic Granulomatous Disease

Introduction: Pancreatitis is an inflammatory disease of the pancreas. Drug-induced pancreatitis is an important cause of pancreatitis. There are two pathological types of acute pancreatitis, including pancreatic edema with a mild course and pancreatic necrosis with a poor prognosis. Some agents can induce pancreatitis, but so far, posaconazole-induced pancreatitis in children has been not reported. Here, we describe the case of a child with acute pancreatitis who received posaconazole. Case Presentation: A 10-year-old girl with a three-year history of chronic granulomatous disease (CGD) was admitted to hospital due to epigastric pain, nausea, vomiting, loss of appetite, and fever for the last four days. The pain was persistent and prominent in the periumbilical area. The patient was on lifelong antifungal prophylaxis for her illness. On abdominal sonography, the head of the pancreas was inflated, which can indicate pancreatitis. All the medications were discontinued at the time of admission, and along with sufficient hydration, acetaminophen was administered for the patient’s pain. One, three, and twelve months after discharge, the patient was visited for follow-up with no signs of stomach discomfort, and the lab data was within the normal limits. CGD is a rare disease in which the phagocytes fail to produce hydrogen peroxide. Such patients are prone to bacterial and fungal infections. Conclusions: In conclusion, this is the second case of posaconazole-induced pancreatitis and the first case in children; thus, we recommend that physicians should be aware of the signs of pancreatitis in high-risk individuals like immunocompromised pediatric population.

Acute pancreatitis after major spine surgery: a case report and literature review

Background

Acute pancreatitis has been described as potential complication of both abdominal and non-abdominal surgeries. The pathogenetic mechanism underlying acute pancreatitis in spine surgery may include intraoperative hemodynamic instability causing prolonged splanchnic hypoperfusion, as well as mechanical compression of the pancreas due to scoliosis correction, with a higher risk in cases of more extended fusions, especially in young adults with lower body mass index (BMI).

Case presentation

We report here a case of postoperative acute pancreatitis with benign evolution in a young female patient after the first and second surgery of a two-stage correction of right thoracic idiopathic scoliosis.

In December 2017, the patient underwent first-stage T4-L3 posterior arthrodesis with T7-T12 osteotomies and temporary magnetic bar. Intraoperative blood loss required massive transfusion. In the immediate postoperative period, the patient started reporting nausea/vomiting, abdominal pain at pressure, moderate meteorism, abdominal distension, hypoactive bowel sounds, and fever. Laboratory tests indicated a progressive increase in aspartate aminotransferase, alanine aminotransferase, serum amylase, lipase, phospho-creatine kinase, and reactive C-protein. A CT scan showed free abundant abdominal fluid in the hepatic, renal, pancreatic, and pelvic regions. After the diagnosis, a hypolipidic diet was initiated, and good hydration per os was maintained. After gastroenterologic consultation, somatostatin, rifaximin, and ursodehoxycholic acid were initiated and maintained for 8 days. In the following days, laboratory tests showed a slow but consistent decrease in liver and pancreatic enzymes until normalization. In January 2018, the patient underwent second-stage surgery with removal of magnetic bar, definitive posterior fusion, and instrumentation T4-L3. Laboratory tests showed a second, even more significant, increase in the amylase and lipase level and a moderate increase in the reactive C-protein. Therapy was maintained until complete normalization of amylase and lipase levels.

Conclusions

Early recognition of symptoms plays a key role in preventing severe morbidity after scoliosis surgery. When symptoms suggest abdominal complication, pancreatic and liver enzymes are to be evaluated for posing prompt diagnosis. Gastroenterologic consultation and eventual imaging are further steps in differential diagnosis and treatment of this rare complication.
