    Abstract Pancreatic tumors in children are infrequently encountered in clinical practice. Their non-specific clinical presentation and overlapping imaging characteristics often make an accurate preoperative diagnosis difficult. Tumors are categorized as epithelial or non-epithelial, with epithelial tumors further classified as tumors of the exocrine or endocrine pancreas. Although both are tumors of the exocrine pancreas, solid pseudopapillary neoplasm is the most prevalent solid pancreatic tumor in children, while pancreatoblastoma is the most common malignant tumor. Insulinoma is the most common pediatric pancreatic tumor of the endocrine pancreas. Malignant tumors require a complete, often radical, surgical resection. However, pancreatic parenchyma-sparing surgical procedures are utilized for benign tumors and low-grade malignancy to preserve gland function. This review will discuss the epidemiology, pathophysiology, clinical and diagnostic characteristics, and management options associated with both common and rare solid pancreatic masses in children. We will also discuss current challenges encountered in their evaluation and treatment.

    Abstract Background: Chronic pancreatitis (CP) can result in opioid dependence and nutritional challenges in children. Total pancreatectomy with islet autotransplantation (TPIAT) is a viable surgical option in appropriately selected patients. We examined differences between children who met criteria for TPIAT versus those who did not and continued with non-operative management.
    Methods: Retrospective observational cohort study of patients evaluated for TPIAT between August 2014 and July 2020 was performed. Cohort-based analyses between TPIAT and non-TPIAT groups were performed.
    Results: Analyses included 121 patients, 69 of whom underwent TPIAT. Demographics, genetic risk factors, and anatomic variants did not differ between groups. TPIAT patients were more likely to have CP (88% vs 71%; p = 0.02), had higher median number of endoscopic retrograde cholangiopancreatography procedures (2.0 vs 1.0; p = 0.0001), and had higher likelihood of opioid use (61% vs 42%; p = 0.04) and nutritional supplementation (23% vs 4%; p = 0.004), compared to non-TPIAT. At 6 months post-TPIAT, patients had lower use of any analgesic pain medications (39% vs 73%; p = 0.0002) and lower use of opioids (9% vs 39%; p = 0.0006), compared to non-TPIAT patients at 6 months after evaluation. At 6 months post-TPIAT, rate of exclusively oral nutrition increased from 77% to 86%, and total parenteral nutrition use decreased from 13% to 0% (p = 0.02).
    Conclusions: In children referred for TPIAT evaluation, there is greater burden of disease in those selected for operation, compared to patients who do not undergo operation. TPIAT achieves lower analgesic pain medication use compared to continuation with non-TPIAT management and achieves freedom from nutritional supplementation. Level of evidence: Retrospective comparative study, Level III.

    Abstract Objectives: Post-ERCP pancreatitis (PEP) is the most common complication of endoscopic retrograde cholangiopancreatography (ERCP). Limited existing data suggest that prophylactic pancreatic duct (PD) stenting in pediatric patients may increase the risk of PEP. The aim of this study is to identify factors associated with PEP in pediatric patients.
    Methods: Patients at a single institution who underwent ERCP between 2012 and 2020 were retrospectively reviewed. Patient and procedure-related factors were collected. Data were analyzed using Chi-square or Fisher exact tests as appropriate and Mann-Whitney-Wilcoxon tests.
    Results: Seven hundred thirty-six ERCPs were performed for 402 unique patients. Ninety-four cases were complicated by PEP (12.8%), of which 91 were mild and 3 were moderately severe. Pancreatic indication, native major papilla, PD cannulation and injection, and higher American Society for Gastrointestinal Endoscopy (ASGE) complexity were associated with PEP. A higher proportion of patients who received rectal indomethacin (65% vs 47%, P = 0.002), or who had placement of a prophylactic (31% vs 20%, P = 0.01) or therapeutic PD stent (37% vs 27%, P = 0.04) developed PEP; however, in a subgroup analysis of high-risk patients, this association was not persistent. A smaller proportion of PEP patients had PRSS1 mutation compared to non-PEP patients (22% vs 40%, P = 0.04).
    Conclusions: This study evaluates factors associated with developing PEP in a large pediatric cohort. A high rate of PEP was observed, likely secondary to higher rates of pancreatic indication and higher ASGE complexity scores compared to previously reported literature. Randomized prospective trials are needed to better define the utility of various interventions.

    Abstract Background: While operational tolerance has been previously described in isolated intestinal transplant, reports of this phenomenon in combined liver-intestine transplant are lacking.
    Case description: We detail a unique case of a patient who received a composite allograft including liver, pancreas, and small bowel due to short gut syndrome secondary to gastroschisis complicated by volvulus. The indication for transplantation was permanent dependence on total parenteral nutrition, end-stage liver disease, recurrent sepsis, and persistent stomal variceal hemorrhage. The patient developed severe graft-versus-host disease with grade 3 skin involvement, ophthalmic, and pulmonary involvement with 53% donor T-cell chimerism. She required aggressive therapy including high-dose methylprednisolone, rituximab, cyclophosphamide, and alemtuzumab. Due to infection concerns following depletion of her lymphocytes, immunosuppression was discontinued with close surveillance of her allograft. Nearly 10 years later, the patient has continued off all immunosuppression without evidence of rejection or graft dysfunction and demonstrates immunocompetence with normal functional immune assays and development of appropriate live vaccination titers.
    Conclusion: This report of operational tolerance following pediatric composite liver-pancreas-intestine transplantation provides evidence that the complex immunologic balance in intestinal transplantation may on rare occasions favor immunosuppression reduction or even discontinuation. Future trials of immunosuppression minimization in this population may be warranted.

    Abstract Pediatric Pancreatitis has gained a lot of attention in the last decade. Updates in medical management include new testing technologies in genetics, function testing and imaging modalities. Updates in surgical management have taken place as well, with total pancreatectomy islet auto transplantation reserved for a specific patient population that meets the clinical criteria. Multidisciplinary team management is needed for patients with chronic pancreatitis to ensure optimal outcomes.

    Abstract We report a rare case of a patient with cystic fibrosis suffering from debilitating abdominal pain due to chronic pancreatitis. This 13-year-old patient was evaluated for surgical intervention to relieve pain from chronic pancreatitis and to improve quality of life. The patient carried two mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene; the most common ΔF508 variant and a second variant, p.Glu1044Gly, which has not been previously described. The patient's condition did not improve despite medical management and multiple endoscopic interventions, and therefore total pancreatectomy with islet autotransplantation and a near-total duodenectomy was offered for definitive management. Patient-derived duodenal crypts were isolated and cultured from the resected duodenum, and duodenal organoids were generated to test CFTR function. Our studies demonstrate that this novel mutation (ΔF508/p.Glu1044Gly) caused severely impaired CFTR function

    Abstract Objectives: This study aims to describe the prevalence of gastrointestinal (GI) symptoms following the first time occurrence of acute pancreatitis (AP) and to measure the impact of the episode on patient health-related quality of life (HRQOL) from the perspectives of patients and parents.
    Methods: Questionnaires regarding GI symptoms 1 year following the initial occurrence of AP were obtained from 74 pediatric patients. Thirty of these patients completed both the Pediatric Quality of Life Inventory (PedsQL) 4.0 Generic Core Scales and the PedsQL Gastrointestinal Symptoms and Worry Scales. These data were compared to legacy-matched healthy controls.
    Results: Children with a standalone occurrence of AP experienced a similar rate of GI symptoms compared to those who progressed to acute recurrent pancreatitis (ARP) within 1 year. PedsQL 4.0 Generic Core Scales scores were significantly lower for children self-report and parent proxy-report for patients that experienced AP compared to healthy controls. AP patients also demonstrated significantly more symptoms than healthy controls in the Gastrointestinal Symptoms and Worry Scales across multiple domains.
    Conclusions: Gastrointestinal symptoms affect many children who experience a single AP event even without recurrent attacks. The burden of symptoms is not significantly different from those who develop ARP. This is a novel study that evaluates patient-reported outcomes in children following an AP attack and demonstrates there is a significant impact on HRQOL in children and family experiences post AP. More data are needed to study the progression of disease and the extended impact of AP following an initial AP attack in pediatric patients.

    Abstract Abstract: Children with acute recurrent and chronic pancreatitis (CP) experience abdominal pain that leads to hospitalizations, opioid dependence, and poor quality of life. Total pancreatectomy with islet autotransplantation (TPIAT) is offered as a surgical option in management of debilitating pancreatitis that fails medical and endoscopic therapy to reduce or eliminate pain. Given that patients with type 1 diabetes mellitus (T1DM) lack insulin-producing β cells, the outcomes from autotransplanting islet isolates back into total pancreatectomy patients with T1DM are not fully known.We performed TPIAT in 2 CP patients who also had a diagnosis of T1DM for at least 6 years before the operation and evaluated the clinical and laboratory outcomes before and after the operation. Postoperatively both patients' abdominal pain had significantly subsided, they were weaned off opioid medications, and they were able to return to full-time school attendance. In addition, total daily dose of insulin in 1 patient was able to be slightly reduced at 12 months post-TPIAT. We observed in vitro that residual α cells and β cells in T1DM islets were able to secrete a small amount of glucagon and insulin, respectively.

    Abstract Background: Studies systematically documenting US findings in children with acute pancreatitis are limited. Pancreas duct dilation is described as the most reliable finding of acute pancreatitis but this has not been rigorously examined in children.
    Objective: To systematically document US findings in children with acute pancreatitis and to define interobserver agreement on those findings.
    Materials and methods: In this cross-sectional study we retrospectively reviewed images for all pediatric patients <18 years of age who had been prospectively enrolled in a registry of patients with index admissions for acute pancreatitis between March 2013 and July 2020. Two blinded observers (R1, R2) reviewed the first transabdominal US examination performed within 2 weeks of the pancreatitis attack for each patient.
    Results: In 141 children, US was performed at a median of 1 day (interquartile range [IQR]: 0, 1) following acute attack. Thirty-three (23%, R1) and 38 (27%, R2) children had no abnormal findings on US. Peripancreatic edema was the most frequent finding documented by both reviewers (63% R1, 54% R2). The pancreatic duct was visible in only 35% of the children and was dilated in only 12% (R1) and 14% (R2). There was substantial to almost-perfect agreement between reviewers on findings of acute pancreatitis (κ=0.62-1), including duct visibility.
    Conclusion: Peripancreatic edema was the most frequently identified finding in children with acute pancreatitis, present in up to 63%, with almost perfect interobserver agreement. Duct dilation, cited in the literature as a reliable finding of acute pancreatitis, was rarely identified in our sample.
