Objectives: Esophageal food impaction (EFI) is the sudden onset of dysphagia that occurs when a food bolus becomes lodged in the esophagus, requiring endoscopic removal. Scientific data on the prevalence and causes of EFI in children is lacking. The aim of this study was to provide further insights into EFI episodes in children., Methods: We have prospectively enrolled all children admitted for a first episode of EFI between March 2018 and March 2023. A fluoroscopic contrast study was performed in all patients to confirm the boluses and assess their position. Boluses were extracted by esophagogastroduodenoscopies, and esophageal biopsies were routinely obtained for histologic evaluation., Results: Over the study period, 41 children were admitted for a first episode of food impaction. Drooling was the most commonly reported symptom. Half children experiencing a first episode of food bolus were diagnosed with EoE (20/41, 48.8%). Almost a fourth of the episodes subtended a different condition, such as esophageal anastomotic, peptic or congenital strictures, stricturing caustic esophagitis, esophageal duplication, and achalasia. In the last fourth of patients the cause of EFI was not identified and thus probably related to quick eating and inadequate chewing of food., Discussion: Our study represents the largest known series of pediatric patients evaluated for food bolus impaction. Our main finding is the high frequency of EoE, which accounts for a half of EFI episodes in pediatric age, especially in older children. This finding highlights the importance of obtaining esophageal biopsies after the endoscopic bolus removal in children with EFI to provide a complete diagnostic evaluation., (© 2024 European Society for Pediatric Gastroenterology, Hepatology, and Nutrition and North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition.)

Objectives: To assess the clinical complications reported after the ingestion of sharp/pointed foreign bodies (FBs) in pediatric age, their incidence among all FB ingestions, and the features and clinical presentation of children., Study Design: We have recruited all consecutive patients aged 0-14 years, admitted for sharp/pointed FB ingestion. Clinical data until hospital discharge were accurately recorded, including both children with esophagogastric FB retention who underwent endoscopic removal and children who were radiologically followed-up till spontaneous FB expulsion. Clinical outcomes were recorded for each patient, with special reference to possible prolonged retention and wall perforation during the intestinal passage., Results: We have enrolled 580 children (males/females: 292/288; age range: 11-180 months; mean age ± standard deviation: 50.5 ± 42 months). Sharp/pointed FBs mainly included fragments of metal 270 of 580 (46.55%) and glass 180 of 580 (31%). FBs were endoscopically removed in 79 of 580 (13.6%) children whereas the remaining FBs passed through the gastrointestinal tract over an overall mean time of 29 hours. No cases of intestinal perforation nor prolonged retention were observed. In 3 of 65 (4.6%) procedures the endoscopist faced an uncomfortable endoscopic removal due to the shape and size of the FB which hampered the retrograde passage through the esophageal sphincters., Conclusions: Our original and extensive data emphasize that accidental ingestion of sharp/pointed FB ingestion is a current issue in pediatric age, especially in toddlers. Metal and glass objects are the most involved FBs and their endoscopic retrieval may not be easy in about 5% of cases. Fortunately, in our pediatric sample no surgical intervention was needed., Competing Interests: The authors report no conflicts of interest., (Copyright © 2022 by European Society for European Society for Pediatric Gastroenterology, Hepatology, and Nutrition and North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition.)

Objectives: Despite the efforts to reduce the exposure to corrosive household products, caustic ingestion in children is currently a significant medical problem. The aims of the present study were to evaluate the clinical consequences of caustic ingestion and to identify prognostic factors that could concur in driving both diagnostic and therapeutic management., Methods: All consecutive children referred for ingestion of a caustic substance from June 2017 to June 2018 were enrolled. Medical records, laboratory and endoscopic findings were reviewed and analyzed., Results: We enrolled 44 children with caustic ingestion. Alkaline agents were ingested by 26 of 44 (59.1%) patients, whereas acid agents were ingested by 18 of 44 patients (40.9%). Alkaline rather than acid agents were associated with a worse endoscopic score (r: 0.45) and a higher probability of early esophageal stricture occurrence (r: 0.38). The specific risk of the presence of severe esophageal lesions rose progressively with increasing number of symptoms whereas no esophageal injury was found in asymptomatic patients., Conclusions: Our data suggest that endoscopic evaluation is mandatory in symptomatic patients to direct therapeutic management, but it could be avoided in asymptomatic patients after accidental ingestion, particularly if the ingestion is only suspected and patients have no oropharyngeal burns.

Objective: Although emerging data indicate that obese/overweight children are more likely to develop functional gastrointestinal disorders (FGIDs) than normal-weight peers, contrasting results have been reported. The present observational, case-control study aimed at estimating the prevalence of FGIDs in obese/overweight children compared to normal-weight peers., Methods: Consecutive obese and overweight children aged 4 to 18 years attending the obesity outpatient clinic were enrolled as study cases. Normal-weight children were enrolled as comparison group. All the enrolled patients received a thorough health examination from both a pediatric endocrinologist and gastroenterologist. Moreover, they were asked to fill out the Rome III questionnaire for the diagnosis of FGIDs. Data were analyzed to compare the prevalence of FGIDs between cases and controls., Results: Throughout the study period we enrolled 103 cases and 115 controls. No significant age and sex differences were found between the 2 groups. FGIDs were significantly more prevalent in obese/overweight compared to normal-weight children (47.57% vs 17.39%; P < 0.0001). Increased prevalence was observed for functional constipation (18.44% vs 7.82%; P = 0.025), functional dyspepsia (23.33% vs 6.95%; P = 0.001), and irritable bowel syndrome (10.67% vs 2.60%; P = 0.024), whereas no difference was observed for functional abdominal pain (1.94% vs 2.60%; P = 1.00)., Conclusions: Our data suggest that there is a link between excess body fat and FGIDs in children. This finding may offer a model of patients in which the effects of food and nutritional substances, the gut microbial environment, and psychosocial factors are fitting well with the emerging biopsychosocial conceptual model for FGIDs.

Constipation is one of the most common gastrointestinal symptoms in children. With a median reported prevalence of 12%, it accounts for about 25% of all pediatric gastroenterology consultations. The majority of children experiences functional constipation and do not usually require any diagnostic testing. For those children not responding to conventional medical treatment or in the presence of a more significant clinical picture, however, an accurate instrumental assessment is usually recommended to evaluate either the underlying pathophysiologic mechanisms or a possible organic etiology. The present review analyzes the possible diagnostic investigations for severely constipated children, focusing on their actual indications and their utility in clinical practice. During the last decade, there has been a remarkable increase in our knowledge of normal and abnormal colonic and anorectal motility in children, and a number of different techniques to measure transit and motility have been developed and are discussed in this narrative review.

Objectives: Childhood functional gastrointestinal disorders (FGIDs) are common conditions associated with significant morbidity and high healthcare costs. This multicenter study aimed at assessing the clinical approach to infants (0-6 months) and children/adolescents (4-18 years) with suspected FGIDs by pediatricians from the Mediterranean Area., Methods: A survey evaluating the diagnostic approach, including the use of Rome II and III criteria, and the therapeutic management of some of the most prevalent FGIDs, such as irritable bowel syndrome (IBS), functional constipation (FC), and functional regurgitation (FR), was distributed to a sample of pediatricians., Results: We collected 278 questionnaires from 9 countries (Croatia, Greece, Israel, Italy, Lebanon, Montenegro, Serbia, Slovenia, and Spain). Rome III criteria are used to diagnose FC by 28.8%. Treatment of FC is based on dietary modifications (97.5%) and osmotic laxatives (93.5%). Rome III criteria are used to diagnose FR by 22.3% of the responders, in contrast to 79.5% who rely on personal experience for diagnosis. Reported treatments mainly consist of reassurance (96.8%) and thickened feedings (77.3%). Nevertheless, 21.2% prescribe proton pump inhibitors or H2-blockers to infants with FR. Rome III criteria are used to diagnose IBS by only 25.9%. Moreover, 86% of the pediatricians base IBS therapy on the predominant symptom. The most prescribed treatments are analgesics (36.6%) for pain control, dietary advice (41.5%) for diarrhea-predominant IBS, and dietary advice (47.8%) for constipation-predominant IBS., Conclusions: Our data show that the use of Rome III diagnostic criteria is not sufficiently widespread among pediatricians, and that large variability remains in the management of FGIDs within the different Mediterranean countries surveyed.

Objective: The clinical relevance of esophageal baseline impedance (BI) remains to be determined. In the present study, we explored the impact of gastroesophageal reflux disease (GERD) and esophageal dysmotility on BI., Methods: A total of 18 children with esophageal atresia, 26 children with GERD, and 17 controls prospectively underwent esophagogastroduodenoscopy and pH-impedance monitoring. BI was measured in both proximal and distal esophagus. Gastroesophageal reflux (GER) and bolus transit indicators were defined according to published criteria., Results: Patients with esophageal atresia showed significantly lower proximal and distal BI values (952 [716-1811] Ω; 895 [284-1189] Ω; respectively) compared with those with GERD (3015 [2368-3975] Ω; 2231 [1770-3032] Ω, P < 0.001 and <0.001, respectively) and controls (3699 [3194-4358] Ω; 3522 [2927-3994] Ω, P < 0.001 and <0.001, respectively). Using linear regression, proximal BI strongly correlated with total bolus transit time (r(2) = 0.61, P < 0.001) and bolus presence time (BPT; r(2) = 0.63, P < 0.001). Distal BI weakly correlated with acid exposure time (r(2) = 0.16, P < 0.01) and longstanding reflux episodes (r(2) = 0.17, P < 0.01), and strongly correlated with total bolus transit time (r(2) = 0.53, P < 0.001) and BPT (r(2) = 0.58, P < 0.001). By logistic regression, BPT predicted low proximal BI values (odds ratio [OR] 1.052; P < 0.05), whereas both GER indicators (acid exposure time: OR 1.56, P < 0.05; longstanding reflux episodes: OR 2.8, P < 0.05) and BPT (OR 1.66, P < 0.01) predicted low distal BI values., Conclusions: Along the length of esophagus, both bolus transit variables and GER significantly affect BI. This suggests that BI may merely mirror phenomena occurring within the esophageal lumen or wall, limiting its value as a discrete clinical entity to replace variables already used for assessing both GERD and esophageal dysmotility.

Background: The pediatric literature about the correlation between symptoms and histological lesions in patients investigated for gastroesophageal reflux disease is scarce and inconclusive. The primary aim of the present study was to assess the relation between the complained symptom severity and the esophageal histological grade, through the use of validated and reliable scores., Methods: All children ages between 2 and 17 years referred to perform upper gastrointestinal endoscopy because of gastroesophageal reflux disease symptoms were asked to complete the Pediatric Gastroesophageal Symptom and Quality of Life validated questionnaire, investigating the main symptoms complained and their impact on daily life and school activities. Esophageal mucosal samples taken during the procedure were analyzed and scored according to the Yerian-Fiocca classification., Results: A total of 164 children were included in the study. No significant association was found between symptomatic score and histological score (r(s): 0.05, P: 0.49). Even when focusing only on adolescents with heartburn or chest pain, no correlation between symptom severity and esophageal lesions was found (r(s): -0.18, P: 0.264). Intercellular space diameter values did not mirror symptom severity., Conclusions: The main finding of this study on children with reflux symptoms is the lack of correlation between symptom severity and esophageal histological grade. The magnitude of intercellular spaces was found not to be related with the clinical score as well.

Background: According to a recent survey, the 2009 North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition-European Society for Pediatric Gastroenterology, Hepatology, and Nutrition gastroesophageal reflux guidelines are poorly adhered to by European primary care pediatricians. The main issue raised from the survey was the prescription of unnecessary acid suppressive medications, especially in infants. No inquiry into the reasons was made. The primary objective of the present study was to assess the applicability of the guidelines in European primary care pediatricians undergoing specific trainings., Methods: One hundred pediatricians involved in the previous survey agreed to participate and were randomly divided into 2 groups: one group was trained in the guidelines through an online podcast and the other group was trained through a synopsis. During the following 3 months, each involved pediatrician was asked to enroll every consecutive infant, child, or adolescent with suggestive reflux symptoms. For every enrolled patient, pediatricians filled in a report concerning their diagnostic and therapeutic choices., Results: A total of 382 patients (boys/girls 186/196, infants/children/adolescents 194/123/65) were enrolled by pediatricians. Infants with unexplained crying and/or distressed behavior who were prescribed proton-pump inhibitors were 3.7% compared with 45.2% of the survey data obtained before the training (P < 0.05). Infants with uncomplicated recurrent regurgitation and vomiting who were prescribed proton-pump inhibitors were 4.5% against 37.1% of the baseline survey data (P < 0.05). The overall rate of children managed in full compliance with the guidelines was 46.1% after the training compared with 1.8% before the training (P < 0.05). No significant differences were seen between pediatricians from podcast and synopsis group., Conclusions: The North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition-European Society for Pediatric Gastroenterology, Hepatology, and Nutrition gastroesophageal reflux guidelines have good applicability, despite that they are presently poorly adhered to by European primary care pediatricians. Simple, inexpensive trainings were proven to be effective in increasing adherence by pediatricians. The increase in compliance clearly favors the role of continuous medical education through simple educational tools and subsequent assessment of practice.

Objective: The aim of this study was to evaluate the current implementation of the 2009 North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition-European Society for Pediatric Gastroenterology, Hepatology, and Nutrition guidelines, and to assess proton pump inhibitors' (PPIs) prescribing patterns among pediatricians from different European countries., Methods: A randomly identified sample of general pediatricians distributed across 11 European countries. They were asked to complete a case report-structured questionnaire investigating their approaches to infants, children, and adolescents with symptoms suggestive of gastroesophageal reflux., Results: A total of 567 European general pediatricians completed the study questionnaire. Only 1.8% of them showed complete adherence to the guidelines. Forty-six percent of them reported that they diagnose gastroesophageal reflux disease based on clinical symptoms irrespective of the age of the child; 39% prescribe PPIs in infants with unexplained crying and/or distressed behavior and 36% prescribe PPIs in infants with uncomplicated recurrent regurgitation and vomiting; 48% prescribed PPIs in children younger than 8 to 12 years with vomiting and heartburn, without specific testing; 45% discontinue PPI therapy abruptly rather than tapering the dose. The overall rate of pediatricians overprescribing PPIs was 82%., Conclusions: The overall results of our survey show that the majority of pediatricians are unaware of 2009 North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition-European Society for Pediatric Gastroenterology, Hepatology, and Nutrition reflux guidelines and often prescribe PPIs despite a lack of efficacy for the symptoms being treated. The overdiagnosis of gastroesophageal reflux disease places undue burden on both families and national health systems, which has not been affected by the publication of international guidelines.

Objectives: The association between GERD and obesity has been frequently reported in adults. Data in children are scarce and inconclusive, evaluating only general obesity. Central adiposity has never been investigated in children as a possible risk factor for GERD. The aims of the present study were to evaluate the prevalence of gastroesophageal reflux disease (GERD) symptoms in overweight and obese children in comparison with a general normal-weight population and whether the GERD symptoms are associated with waist circumference (WC)., Methods: The study population consisted of 153 healthy children. A detailed clinical history and a physical examination were obtained from each patient. A questionnaire on reflux symptoms was completed by caregivers., Results: The reflux symptomatic score resulted significantly higher in obese than in normal-weight children and in children with WC >90th percentile compared with those with WC <75th percentile., Conclusions: These preliminary data show that both total and abdominal obesity are risk factors for the development of GERD symptoms in children. The risk of GERD symptoms rises progressively with the increase in both body mass index and waist circumference, even in normal-weight children.

Constipation is a common and distressing pediatric problem. Even if prevalence of this disorder has increased, treatment of constipation in children is still largely based on clinical experience rather than on evidence-based studies. The currently recommended treatment includes education, disimpaction, and maintenance therapy, consisting of dietary changes, behavioral modification, and use of laxatives. Among osmotic agents, polyethylene glycol solutions appear to be the first-line drug to use in pediatrics. Although these measures are effective in the majority of children, a sizable proportion needs long-term therapy. Chronicity may significantly interfere with the child's emotional growth and development. Advances in the understanding of the gastrointestinal enteric nervous system and epithelial function have led to the development of new classes of drugs. These include substances that bind to serotonin receptors or are chloride channel activators. Further studies are needed to assess the benefits and the risks of these new drugs.
