INTRODUCTION Chronic rhinosinusitis is common among individuals with cystic fibrosis (CF) and has an impact on quality of life. Sinus surgery is a treatment option, but minimal literature exists regarding prevalence and indications. METHODS Using the linked CF Foundation Patient Registry (CFFPR) - Pediatric Health Information Systems (PHIS) database, we investigated variability in receipt of surgery, predictors of surgery, and time to first surgery. We included individuals less than 18 receiving care between 2006 and 2015 at a CF Foundation care program that is also a PHIS-participating-hospital. We used logistic regression to examine predictors of receipt of surgery and a Kaplan-Meier curve to examine time to first surgery among those born 2005-2007. RESULTS There were 11,545 children and adolescents and 2156 (18.7%) received at least one surgery. Variation in number of surgeries was observed across hospitals (median: 63 [IQR, 33-110]). There was an inconsistent pattern between receipt of surgery and markers of disease severity; those receiving surgery having increased odds of treatment use and pulmonary exacerbations and decreased odds of lower lung function and body mass index. Among the cohort of young children, 159 (14%) had at least one surgery with a median age at first surgery of 5.6 (IQR, 3.9-7.0). CONCLUSIONS The use of sinus surgery is frequent, but variable, among children and adolescents. Clinical factors are associated with receipt of surgery, but further understanding is needed on other factors that impact variability in use. Our study indicates the need for additional evaluation of the management of CF-related CRS and indications for surgery.

Background Evidence-based management of gastrointestinal (GI) and nutrition manifestations of cystic fibrosis (CF) is limited, and practice variations have not been studied. Methods Thus, a survey was developed with the purpose of evaluating current nutrition practices of CF-focused gastroenterologists, specifically utilizing awardees and mentors of the Cystic Fibrosis Foundation (CFF) Developing Innovative GastroEnterology Specialty Training (DIGEST) Program. Topics included appetite stimulation, tube feeding (TF), and aspects of nutrition assessment, specifically urine sodium and essential fatty acid (EFA) status. Results The response rate was 61% (22/36). About half (55%; 12/22) of respondents had 5-10 years of experience in GI, and 23% (5/22) had >10 years. In regard to appetite stimulation, the majority used cyproheptadine; however, duration and pattern of prescribing varied. Variation was noted in TF management pertaining to tube placement, formula choice, and prescribing pancreatic enzyme replacement therapy with overnight TF. The majority did not check EFAs or urine sodium. Treatment for deficiencies in EFA or abnormal urine sodium was inconsistent. Conclusion The survey reveals wide variation in management of some aspects of nutrition-related manifestations of CF among experienced providers. This reflects the need for research to provide evidence-based guidelines.

INTRODUCTION This study was designed to evaluate outcomes in pediatric patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) as compared with an American Society of Gastrointestinal Endoscopy (ASGE) complexity grade-matched adult cohort. METHOD In this retrospective case-control study, ERCPs performed in pediatric patients from January 2008 to December 2018 in 2 tertiary referral hospitals were compared with a complexity-matched adult control group with similar procedural indications. Primary outcomes included the clinical success rate, technical success rate, and complication rate. Secondary outcomes included postprocedural admission rates, mode of sedation, procedure time, fluoroscopy time, hospitalization length, and the number of repeat procedures. RESULTS Two hundred thirty-two ERCPs performed in 110 pediatric patients (average age 13.3) and 318 ERCPs performed in 160 ASGE grade-matched adult controls (average age 47.2 years) were analyzed. All procedures were therapeutic. There was no difference in the technical success rate (P = 0.2), clinical success rate (P = 0.5), complication rates (P = 0.1), and fluoroscopy time (P = 0.4), between the pediatric and adult cohorts. General anesthesia use and length of stay were significantly higher in the pediatric group (P = 0.0001). In subgroup analysis, technical (P = 0.2) and clinical success (P = 0.2) as well as complication rates (P = 0.6) were comparable between patients 10 years or less and patients 11 to 18 years within pediatric cohort. CONCLUSIONS ERCP in pediatric cohorts appears to be safe and effective with equivalent outcomes relative to an ASGE complexity-matched adult cohort. Pediatric patients are more likely to require general anesthesia and have a longer average length of stay relative to adult controls.

The Pancreas Committee of the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition aims to promote awareness of pediatric pancreatic diseases, support clinical and basic science research in the field, educate pediatric gastroenterologists, and advocate on behalf of pediatric patients with pancreatic disorders. At the 2017 Annual North American Society for Pediatric Gastroenterology, Hepatology and Nutrition meeting, the Pancreas Committee held a full day symposium on pediatric pancreatic diseases, entitled, "Frontiers in Pediatric Pancreatology." The symposium served as a timely and novel academic meeting that brought together individuals with a vested interest in the care of children with pancreatic disorders. The objective of this day-long course was to update practicing gastroenterologists on the latest advances in research, management algorithms, endoscopic therapies, radiographic resources, surgical approaches, and novel drug therapies targeted to pediatric pancreatitis. Presentations were divided into 4 modules: diagnosis, risk factors, and natural history of pancreatitis; pancreatic imaging and exocrine function; management of pancreatitis; and new frontiers in pediatric pancreatitis research. The course fostered a unique ecosystem for interdisciplinary collaboration, in addition to promoting discussion and stimulating new research hypotheses regarding pediatric pancreatic disorders. Oral presentations by experts in various fields of pancreatology led to thought-provoking discussion; in addition, a meet-the-professor luncheon stimulated critical evaluation of current research in pediatric pancreatic diseases, highlighting knowledge gaps and future research endeavors. The current report summarizes the major learning points from this novel symposium focusing on the growing demographic of pediatric pancreatic diseases.

Background:Although the incidence of acute pancreatitis (AP) in children is increasing, management recommendations rely on adult published guidelines. Pediatric-specific recommendations are needed.Methods:The North American Society for Pediatric Gastroenterology, Hepatology and Nutrition Pan

Pulmonary disease is the primary cause of morbidity and mortality in people with cystic fibrosis (CF), but significant involvement within gastrointestinal, pancreatic, and hepatobiliary systems occurs as well. As in the airways, defects in CFTR alter epithelial surface fluid, mucus viscosity, and pH, increasing risk of stasis through the various hollow epithelial-lined structures of the gastrointestinal tract. This exerts secondary influences that are responsible for most gastrointestinal, pancreatic, and hepatobiliary manifestations of CF. Understanding these gastrointestinal morbidities of CF is essential in understanding and treating CF as a multisystem disease process and improving overall patient care.

Objectives: Wide variations exist in how physicians manage the nutritional aspects of children affected by acute pancreatitis (AP), acute recurrent pancreatitis (ARP), and chronic (CP) pancreatitis. Better consensus for optimal management is needed. Methods: This consensus statement on nutrition in pediatric pancreatic diseases was developed through a joint ESPGHAN-NASPGHAN working group that performed an evidence-based search of the literature on nutrition in AP, ARP, and CP with a focus on pediatrics. The literature was summarized, quality of evidence reviewed, and expert recommendations developed. The authorship met to discuss the evidence and statements. Voting on recommendations occurred over 2 rounds based on feedback. A consensus of at least 75% was required to approve a recommendation. Areas requiring further research were identified. Results and Discussion: The literature on nutrition in pediatric pancreatitis is limited. Children with mild AP benefit from starting an early nutritional regimen in the course of the attack. Early nutrition should be attempted in severe AP when possible; enteral nutrition is preferred over parenteral nutrition. Children with ARP are likely to tolerate and benefit from a regular diet. Children with CP need ongoing assessment for growth and nutritional deficiencies, exocrine and endocrine insufficiencies. Conclusions: This document presents the first authoritative recommendations on nutritional considerations in pediatric pancreatitis. Future research should address the gaps in knowledge particularly relating to optimal nutrition for AP in children, role of diet or dietary supplements on recurrent attacks of pancreatitis and pain episodes, monitoring practices to detect early growth and nutritional deficiencies in CP and identifying risk factors that predispose children to these deficiencies.

Vitamin D is critical for skeletal health; hypovitaminosis D is common in pediatric inflammatory bowel disease (IBD), yet optimal repletion therapy is not well studied. We aimed to conduct a pilot trial comparing the efficacy of 2 vitamin D regimens of weekly dosing for the repletion of hypovitaminosis D in pediatric IBD.Subjects identified from our IBD clinic with 25-hydroxyvitamin D (25[OH]D) concentrations30 ng/mL were randomized to 10,000 (n = 18) or 5000 (n = 14) IU of oral vitamin D3/10 kg body weight per week for 6 weeks. Serum 25(OH)D, Ca, and parathyroid hormone concentrations were measured at baseline, week 8, and week 12.In the higher dosing group, serum 25(OH)D increased from 23.7 ± 8.5 ng/mL at baseline to 49.2 ± 13.6 ng/mL at 8 weeks; P 0.001. In the lower dosing group, serum 25(OH)D increased from 24.0 ± 7.0 ng/mL at baseline to 41.5 ± 9.6 ng/mL at 8 weeks; P 0.001. At 12 weeks, serum 25(OH)D concentrations were 35.1 ± 8.4 and 30.8 ± 4.2 ng/mL for the higher and lower dose regimens, respectively. Mean serum Ca and parathyroid hormone concentrations did not significantly change during the study. No patient exhibited hypercalcemia, and no serious adverse events occurred.Both treatment arms were safe and effective at normalizing vitamin D nutriture in pediatric IBD. Although significant repletion of 25(OH)D concentration was achieved in both dosing groups at 8 weeks, this effect was lost by the 12-week follow-up. Maintenance vitamin D therapy following initial repletion is likely required to maintain long-term normalized vitamin D status.
