Abstract
Pediatric gastrointestinal imaging plays a crucial role in evaluating and managing digestive system disorders in children. This comprehensive review dives into the nuances of pediatric gastrointestinal imaging techniques, focusing on three specific modalities: gastric emptying scintigraphy (GES), intestinal transit scintigraphy (ITS), and gastrointestinal bleeding scintigraphy. GES involves real-time monitoring of stomach emptying using radiotracers and gamma camera technology. While challenges exist in standardizing protocols due to age-specific meal compositions, GES remains pivotal in diagnosing motility disorders, gastroesophageal reflux, and abdominal pain in children. ITS, utilizing [67Ga], provides insights into gastrointestinal motility disorders such as Hirschsprung disease. It aids in whole-gut transit evaluation, guiding surgical interventions and improving long-term clinical outcomes. Gastrointestinal bleeding scintigraphy, employing [99mTc], assists in diagnosing conditions like Meckel's diverticulum and occult bleeding, offering continuous monitoring to pinpoint the bleeding site along the entire gastrointestinal tract. SPECT-CT improves the accuracy and the standards of care. Each technique's protocol details, clinical indications, and diagnostic capabilities are thoroughly discussed, highlighting the importance of these non-invasive, functional imaging modalities in pediatric gastroenterology.

Abstract
INTRODUCTION Pediatric gastrointestinal motility disorders represent some of the most challenging clinical conditions with largely undefined pathogenetic pathways and therefore limited therapeutic options. Herein, we provide an overview of the recent advances in treatment options for these disorders and their clinical impact. AREAS COVERED PubMed and Medline databases were searched for relevant articles related to the treatment of achalasia, esophageal atresia, gastroparesis, PIPO and constipation published between 2017 and 2022. In this article, we review and summarize recent advances in management of gastrointestinal motility disorders in children with a particular focus on emerging therapies as well as novel diagnostic modalities that help guide their application or develop new, more targeted treatments. EXPERT OPINION Gastrointestinal motility disorders represent one of the most challenging conundrums in pediatric age and despite significant advances in investigative tools, the palette of treatment options remain limited. Overall, while pharmacological options have failed to bring a curative solution, recent advances in minimal invasive therapeutic and diagnostic techniques have emerged as potential keys to symptom and quality of life improvement, such as ENDOFLIP, POEM, cine-MRI, fecal microbiota transplantation.

PLoS One 2022; 17:e0266995.

Abstract
PURPOSE Esophageal atresia (EA) is a congenital anomaly of the foregut. Although the survival has improved over the years there is a significant gastrointestinal morbidity affecting physical function and health-related quality of life. The aims of the study were to identify and evaluate predictors of histopathological esophagitis in infants and adolescents with EA. METHODS Single centre, cross-sectional study including one and 15-year-old patients operated for EA that participated in the national follow-up programme between 2012 and 2020 according to a pre-established protocol including upper endoscopy with oesophageal biopsies and 24h-pH-test. Data was collected from patients' medical records and pH-analysis software. Regression models were used to identify predictors of histopathological oesophagitis. Possible predictors were abnormal reflux index, endoscopic esophagitis, hiatal hernia, symptoms of gastroesophageal reflux (GER) and age. RESULTS 65 patients were included, 47 children and 18 adolescents. All children were treated with PPI during their first year of life. Symptoms of GER were reported by 13 (31.7%) of the infant's caregivers, 34 of the children (72.3%) had abnormal reflux index and 32 (68.1%) had histopathological esophagitis. The corresponding numbers for adolescents were 8 (50%), 15 (83.3%) and 10 (55.6%). We found no significant associations between histopathological esophagitis and endoscopic esophagitis, symptoms of GER, hiatus hernia or age group. Abnormal reflux index was an independent predictor of histopathological esophagitis. Seven patients with normal reflux index had histopathological esophagitis, all grade I. CONCLUSIONS We found a high prevalence of histopathological esophagitis despite PPI treatment in accordance with recommendations. No significant difference between the two age groups was seen. Abnormal reflux index was an independent predictor of histopathological esophagitis. However, we cannot recommend the use of pH-metry as a substitute for esophageal biopsies; future studies are needed to elucidate if esophageal biopsies might be postponed in infants with normal reflux index.

Wollmer E, Ungell AL, Nicolas JM, Klein S. Review of paediatric gastrointestinal physiology relevant to the absorption of orally administered medicines. Adv Drug Deliv Rev 2022; 181:114084. [PMID: 34929252 DOI: 10.1016/j.addr.2021.114084] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2021] [Revised: 11/13/2021] [Accepted: 12/13/2021] [Indexed: 12/11/2022]
Abstract
Despite much progress in regulations to improve paediatric drug development, there remains a significant need to develop better medications for children. For the design of oral dosage forms, a detailed understanding of the specific gastrointestinal (GI) conditions in children of different age categories and how they differ from GI conditions in adults is essential. Several review articles have been published addressing the ontogeny of GI characteristics, including luminal conditions in the GI tract of children. However, the data reported in most of these reviews are of limited quality because (1) information was cited from very old publications and sometimes low quality sources, (2) data gaps in the original data were filled with textbook knowledge, (3) data obtained on healthy and sick children were mixed, (4) average data obtained on groups of patients were mixed with data obtained on individual patients, and (5) results obtained using investigative techniques that may have altered the outcome of the respective studies were considered. Consequently, many of these reviews draw conclusions that may be incorrect. The aim of the present review was to provide a comprehensive and updated overview of the available original data on the ontogeny of GI luminal conditions relevant to oral drug absorption in the paediatric population. To this end, the PubMed and Web of Science metadatabases were searched for appropriate studies that examined age-related conditions in the oral cavity, esophagus, stomach, small intestine, and colon. Maturation was observed for several GI parameters, and corresponding data sets were identified for each paediatric age group. However, it also became clear that the ontogeny of several GI traits in the paediatric population is not yet known. The review article provides a robust and valuable data set for the development of paediatric in vitro and in silico biopharmaceutical tools to support the development of age-appropriate dosage forms. In addition, it provides important information on existing data gaps and should provide impetus for further systematic and well-designed in vivo studies on GI physiology in children of specific age groups in order to close existing knowledge gaps and to sustainably improve oral drug therapy in children.

Abstract
Current paediatric anaesthetic fasting guidelines have recommended conservative fasting regimes for many years and have not altered much in the last decades. Recent publications have employed more liberal fasting regimes with no evidence of increased aspiration or regurgitation rates. In this first solely paediatric European Society of Anaesthesiology and Intensive Care (ESAIC) pre-operative fasting guideline, we aim to present aggregated and evidence-based summary recommendations to assist clinicians, healthcare providers, patients and parents. We identified six main topics for the literature search: studies comparing liberal with conservative regimens; impact of food composition; impact of comorbidity; the use of gastric ultrasound as a clinical tool; validation of gastric ultrasound for gastric content and gastric emptying studies; and early postoperative feeding. The literature search was performed by a professional librarian in collaboration with the ESAIC task force. Recommendations for reducing clear fluid fasting to 1 h, reducing breast milk fasting to 3 h, and allowing early postoperative feeding were the main results, with GRADE 1C or 1B evidence. The available evidence suggests that gastric ultrasound may be useful for clinical decision-making, and that allowing a 'light breakfast' may be well tolerated if the intake is well controlled. More research is needed in these areas as well as evaluation of how specific patient or treatment-related factors influence gastric emptying.

Abstract
BACKGROUND There are no pediatric norms for gastric emptying (GE) measured by nuclear scintigraphy. The 13 C-labeled, stable isotope GE breath test (GEBT) is a non-radioactive alternative. We aimed to determine normative GEBT ranges in a cohort of healthy children and examine the influence of age, gender, puberty, and body surface area (BSA). METHODS Healthy children ages 8-18 years completed the [13 C]-Spirulina platensis GEBT after an overnight fast. Breath samples were collected at baseline, every 15 min × 1 h, then every 30 min for 4 h total. The 13 CO2 excretion rate was determined by the change in 13 CO2 /12 CO2 over time in each breath sample, expressed as kPCD (Percent 13 C Dose excreted/min). A mixed model with random time was used for multivariable analysis and outcome fit into a quadratic model. KEY RESULTS The 100 subjects completed the test meal within allotted time. Median (IQR) age was 13.5 (11.3-15.5) years; 51% were female. Females had lower 13 CO2 excretion rates (slower GE) than males across time (p < 0.001) while decreased excretion rates correlated with higher BSA (p = 0.015). Gender differences were also noted within pubertal stages with females showing slower GE. Multivariable analysis suggested that pre-pubertal children have faster GE than both peri- and post-pubertal groups (p < 0.0001). CONCLUSIONS & INFERENCES Gender, puberty, and BSA influence GE rates in healthy children more than age. Although further data are needed, pubertal stage and hormonal influences may be unique factors to consider when assessing GE in children.

Gastric emptying of milk in infants and children up to 5 years of age: normative data and influencing factors. Pediatr Radiol 2020; 50:689-697. [PMID: 31993707 DOI: 10.1007/s00247-020-04614-3] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2019] [Revised: 10/28/2019] [Accepted: 01/09/2020] [Indexed: 11/25/2022]
Abstract
BACKGROUND Gastric emptying scintigraphy is widely used in infants and children, but there is a lack of age-specific normative data. OBJECTIVE The objectives of this retrospective study were: 1) to establish a range of gastric emptying of milk or formula as a surrogate for normal gastric emptying in infants and young children ≤5 years of age, and 2) to investigate the effects of patient age, feeding volume, feeding route and gastroesophageal reflux on gastric emptying. MATERIALS AND METHODS The reports of 5,136 gastric emptying studies of children ≤5 years of age performed at Children's National Medical Center from January 1990 to August 2012 were reviewed. Demographic data, 1-h and 3-h gastric emptying values and gastroesophageal reflux status of all patients were stored in a database. Using stringent inclusion and exclusion criteria, the studies of patients as similar to healthy children as possible were selected for this study. RESULTS The study group included 2,273 children (57% male) ages 0-59 months (median: 4.6 months). The median 1-h gastric emptying was 43% (interquartile range [IQR] 34-54%). The median 3-h gastric emptying was 91% (IQR 79-98%). Sixty-one percent of patients with 1-h gastric emptying value of <50% had 3-h gastric emptying ≥80%. Gastric emptying was significantly faster in children ≤6 months as compared with all older age groups. In each age group, the median gastric emptying decreased with increasing feeding volume. Gastric emptying was significantly faster in patients fed via combined nasogastric tube and oral routes as compared with those fed exclusively orally. There was no significant difference in gastric emptying of children with and without gastroesophageal reflux. CONCLUSION Although there are statistically significant differences in gastric emptying based on age, volume and route of feeding, the data suggest that overall normal liquid gastric emptying in infants and children ≤5 years of age is ≥80% at 3 h. One-hour emptying measurements are not reliable for detecting delayed gastric emptying.

Abstract
BACKGROUND Due to scarcity of scientific literature on pediatric gastroparesis, there is a need to summarize current evidence and identify areas requiring further research. The aim of this study was to provide an evidence-based review of the available literature on the prevalence, pathogenesis, clinical presentation, diagnosis, treatment, and outcomes of pediatric gastroparesis. METHODS A search of the literature was performed using the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines with the following databases: PubMed, EMBASE, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, and Web of Science. Two independent reviewers screened abstracts for eligibility. KEY RESULTS Our search yielded 1085 original publications, 135 of which met inclusion criteria. Most articles were of retrospective study design. Only 12 randomized controlled trials were identified, all of which were in infants. The prevalence of pediatric gastroparesis is unknown. Gastroparesis may be suspected based on clinical symptoms although these are often non-specific. The 4-hour nuclear scintigraphy scan remains gold standard for diagnosis despite lack of pediatric normative comparison data. Therapeutic approaches include dietary modifications, prokinetic drugs, and postpyloric enteral tube feeds. For refractory cases, intrapyloric botulinum toxin and surgical interventions such as gastric electrical stimulation may be warranted. Most interventions still lack rigorous supportive data. CONCLUSIONS Diagnosis and treatment of pediatric gastroparesis are challenging due to paucity of published evidence. Larger and more rigorous clinical trials are necessary to improve outcomes.

Abstract
INTRODUCTION Post-prandial hyperinsulinaemic hypoglycaemia (PPHH) is a recognized complication of various gastric surgeries in children, but rarely reported after oesophageal atresia repair. We report 2 children diagnosed with PPHH after oesophageal surgery and the challenges of their management. Case 1: A 2-year-old boy diagnosed with oesophageal atresia at birth was surgically repaired requiring 6 oesophageal dilatations in the first year of life. At 11 months of age, he manifested hypoglycaemic seizures and investigations confirmed PPHH. Acarbose and diazoxide trials failed. He was managed with 17-h continuous gastrostomy feeds. Currently, he is 28 months old with euglycaemia on daytime bolus gastrostomy feeds and overnight 12-h continuous gastrostomy feeds. Case 2: A 6-month-old girl diagnosed with Wolf-Hirschhorn syndrome and tracheo-oesophageal fistula was surgically repaired, requiring monthly oesophageal dilatations. At 5 months of age, she was reported to have hypoglycaemia and PPHH was confirmed. She responded to diazoxide and continuous nasogastric tube feeds, but developed pulmonary hypertension pos-sibly diazoxide-induced. Subsequently, diazoxide was stopped and normoglycaemia was secured via 20-h continuous gastrostomy feeds. CONCLUSION PPHH may be an underdiagnosed complication in children undergoing surgery for oesophageal atresia. These children must be monitored closely for symptoms of hypoglycaemia and if there are concerns must be screened for possible PPHH. Our cases demonstrate that continuous feeding regimens might be the only therapeutic option, until PPHH gradually lessens in intensity over time.

Abstract
Oesophageal atresia (EA) is a congenital abnormality of the oesophagus that is caused by incomplete embryonic compartmentalization of the foregut. EA commonly occurs with a tracheo-oesophageal fistula (TEF). Associated birth defects or anomalies, such as VACTERL association, trisomy 18 or 21 and CHARGE syndrome, occur in the majority of patients born with EA. Although several studies have revealed signalling pathways and genes potentially involved in the development of EA, our understanding of the pathophysiology of EA lags behind the improvements in surgical and clinical care of patients born with this anomaly. EA is treated surgically to restore the oesophageal interruption and, if present, ligate and divide the TEF. Survival is now ~90% in those born with EA with severe associated anomalies and even higher in those born with EA alone. Despite these achievements, long-term gastrointestinal and respiratory complications and comorbidities in patients born with EA are common and lead to decreased quality of life. Oesophageal motility disorders are probably ubiquitous in patients after undergoing EA repair and often underlie these complications and comorbidities. The implementation of several new diagnostic and screening tools in clinical care, including high-resolution impedance manometry, pH-multichannel intraluminal impedance testing and disease-specific quality of life questionnaires now provide better insight into these problems and may contribute to better long-term outcomes in the future.

Abstract
Oesophageal atresia and tracheoesophageal fistula (OA-TOF) are a multifaceted condition which affects patients throughout their lives. Even though it is one of the most common gastrointestinal malformations, most of the current studies focus on gastro-oesophageal reflux disease, anastomotic strictures, and feeding difficulties. However, there is increasing evidence that a proportion of patients with OA-TOF also have abnormal gastric function. This review aims to provide a comprehensive understanding of studies of gastric function in patients with OA-TOF. The etiology of this abnormality has been hypothesized to be congenital and/or acquired. Several modalities are currently available for the investigation of gastric function, each of them trying to answer specific clinical questions. This review summarizes the studies that have looked at gastric function in the OA-TOF cohort with gastric emptying studies (gastric emptying scintigraphy and 13C octanoic breath test), gastric manometry, electrogastrography, and oral glucose tolerance test. However, these modalities are limited due to poor age-specific normative values and heterogeneous methodologies used. The evaluation of symptoms in this cohort is crucial, modalities for abnormal gastric function are also described. With appropriate investigations and symptoms questionnaires, treatment strategies can be implemented to correct abnormal gastric function and thereby improve the outcomes and quality of life of patients with OA-TOF. This review highlights the need for large international multicentre collaborative studies and high-quality prospective randomized controlled trials to improve our understanding of gastric function in this cohort.

Abstract
BACKGROUND (99m) Technetium scintigraphy ((99m) TS) is the 'gold standard' for measuring gastric emptying (GE), but it is associated with a radiation exposure. For this reason, the (13) C-octanoic acid breath test ((13) C-OBT) was developed for measuring GE of solids. The objective of this study was to determine normal values for gastric half-emptying time (t1/2 GE) of solids in healthy children. METHODS Gastric emptying of a standardized solid test meal consisting of a pancake evaluated with (99m) TS and (13) C-OBT was compared in 22 children aged between 1 and 15 years with upper gastrointestinal symptoms. Subsequently, the (13) C-OBT was used to determine normal values for GE of the same solid test meal in 120 healthy children aged between 1 and 17 years. KEY RESULTS The results showed a significant correlation (r = 0.748, p = 0.0001) between t1/2 GE measured with both techniques in the group of children with upper gastrointestinal symptoms. In the group of healthy children, mean t1/2 GE was 157.7 ± 54.0 min (range 71-415 min), but t1/2 GE decreased with age between 1 and 10 years and remained stable afterward. There was no influence of gender, weight, height, body mass index, and body surface area on t1/2 GE. CONCLUSIONS & INFERENCES Normal values for GE of solids measured with the (13) C-OBT using a standardized methodology were determined in healthy children. We propose to use this method and corresponding reference ranges to study GE of solids in children with gastrointestinal problems.

Abstract
Esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) is a rare congenital malformation. Digestive and nutritional problems remain frequent in children with EA both in early infancy and at long-term follow-up. These patients are at major risk of presenting with gastroesophageal reflux and its complications, such as anastomotic strictures. Esophageal dysmotility is constant, and can have important consequences on feeding and nutritional status. Patients with EA need a systematic follow-up with a multidisciplinary team.

Abstract
BACKGROUND AND AIM Disorders of gastric emptying constitute an important group of conditions in children. The diagnostic gold standard is scintigraphy, and recommendations for standardization have been published with adult normative data. Pediatric literature lacks standardized age specific normative values. Our aim was to establish normal values of solid phase gastric emptying utilizing scintigraphy in children (5-18 years) using the recommended imaging protocol and standardized meal. METHODS Gastric emptying was assessed by scintigraphy of a (99m) Tc-labeled vegetarian meal. Image acquisition was dynamic for first hour and static at 2, 3, and 4 h. Results were reported as percent intragastric retention; lag phase defined as time to 5% emptying. RESULTS Thirty (17 boys) healthy children, mean ages of 9.5 ± 3.1 (range 5 to 16) years, were enrolled. Median values (5th and 95th percentiles) for percent gastric retention at 30 min, 1, 2, 3 and 4 h were 90% (76 and 100%), 77% (56 and 96%), 33% (10 and 71%), 16% (3 and 44%), and 7% (0.5 and 22%). The median (5th and 95th percentiles) lag phase was 18 min (6 and 60 min). Lag phase had no correlation with gastric retention at 4 h. CONCLUSIONS This study provides valuable normative ranges for solid phase gastric emptying in children. Using adult normative data in children may be inappropriate.

Abstract
BACKGROUND Both esophageal atresia (EA) and duodenal atresia (DA) involve deficient anti-reflux barrier, poor esophageal function and eventually, duodenogastric reflux. This study aims at examining the upper gastrointestinal functional status in a cohort of patients with both EA and DA. METHODS A retrospective survey of patients treated for EA and DA between 1965 and 2012 was conducted. Clinical charts, office visits, imaging, upper gastrointestinal endoscopy and esophageal pH metry/impedance were used to assess the long-term condition of the esophagus, the presence of gastroesophageal reflux disease (GERD) and/or the need for fundoplication. RESULTS Twenty out of 581 patients treated for EA had associated DA. Ten/twenty children survived; 1 had primary esophageal replacement. With a median follow-up of 9 years, 8/9 had complicated outcomes and 5 still suffered digestive ailments: 2 GER; 1 eosinophilic esophagitis; 1 nodular gastritis, and 1 wrap herniation. A total of 10 procedures were performed: 8 fundoplications, 1 esophagogastric dissociation and 1 replacement with colon. DISCUSSION The association of EA with DA involves a poor upper digestive function with high risks of GERD and fundoplication failure. The lifelong synergistic play of esophageal, gastric and duodenal dysfunctions in these patients prompts long-term follow-up, and eventually active treatment.

Abstract
PURPOSE To evaluate the mechanisms underlying gastroesophageal reflux (GER) following esophageal atresia (EA) repair and gastroesophageal function in infants and adults born with EA. METHODS Ten consecutive infants born with EA as well as 10 randomly selected adult EA patients were studied during their first postoperative follow-up visit and a purposely planned visit, respectively. A (13)C-octanoate breath test and esophageal pH-impedance-manometry study were performed. Mechanisms underlying GER and esophageal function were evaluated. RESULTS Transient lower esophageal sphincter relaxation (TLESR) was the most common mechanism underlying GER in infants and adults (66% and 62%, respectively). In 66% of all GER episodes, no clearing mechanism was initiated. On EFT, normal motility patterns were seen in six patients (four infants, two adults). One of these adults had normal motility overall (>80% of swallows). Most swallows (78.8%) were accompanied by abnormal motility patterns. Despite this observation, impedance showed normal bolus transit in 40.9% of swallows. Gastric emptying was delayed in 57.1% of infants and 22.2% of adults. CONCLUSIONS TLESR is the main mechanism underlying GER events in patients with EA. Most infants and adults have impaired motility, delayed bolus clearance, and delayed gastric emptying. However, normal motility patterns were seen in a minority of patients.

Abstract
OBJECTIVES The aims of the present study was to define the clinical features, response to therapy, and outcome of pediatric gastroparesis. METHODS Retrospective review of 230 children with gastroparesis. Demographics, gastric emptying times, symptoms, response to medications, and outcome were determined for each of 3 groups (infants, children, and adolescents). RESULTS Mean age was 9 years, with boys predominating among infants and girls among adolescents. Postviral gastroparesis occurred in 18% and mitochondrial dysfunction (MD) in 8%. Symptoms varied with age, with children experiencing more vomiting and adolescents reporting more nausea and abdominal pain. The addition of promotility drugs was an effective therapy. Overall rates of symptom resolution were 22% at 6 months, 53% at 18 months, and 61% at 36 months, with median time to resolution of 14 months. Factors associated with symptom resolution included younger age, male sex, postviral gastroparesis, shorter duration of symptoms, response to addition of promotility therapy, and absence of MD. In multivariate analysis, longer duration of symptoms and MD both predicted lower rates of resolution, whereas younger age and response to addition of promotility therapy predicted a higher rate. CONCLUSIONS Pediatric gastroparesis is a complex condition with variable symptomatology and outcome depending on multiple parameters. Understanding the clinical features and response to therapy will improve our diagnosis and treatment of this disorder.

Abstract
BACKGROUND Botulinum toxin A has been used in children to treat spastic disorders and recently for GI conditions. Open-label studies in adults with gastroparesis have reported an improvement in symptoms and gastric emptying after endoscopic intrapyloric botulinum injections (IPBIs), although placebo-controlled trials have shown conflicting results. Only a single case report of IPBI is available in children. OBJECTIVE To determine the long-term clinical outcomes and predictive factors for IPBI response in children with gastroparesis refractory to medical therapy. DESIGN Retrospective review. SETTING Single tertiary care center. PATIENTS Children with refractory gastroparesis symptoms undergoing IPBIs. INTERVENTIONS IPBIs. MAIN OUTCOME MEASUREMENTS Clinical improvement and predictive factors for response. RESULTS A total of 70 injections were given to 47 patients (mean age 9.98 ± 6.5 years; 23 female patients) with follow-up in 45 patients. IPBI failed in 15 patients and was successful in 30 patients. The median duration of response to the first IPBI was 3.0 months (95% CI, 1.2-4.8). A total of 29 patients received a single IPBI, and 18 received multiple IPBIs. Older age and vomiting predicted response to initial IPBI, and male sex predicted response to repeat IPBI. Only 1 patient reported exacerbation of vomiting after IPBI resolving within a week. LIMITATIONS The open-label and retrospective nature of the study. CONCLUSION IPBI is safe and may be effective in the management of children with symptoms of gastroparesis. Subgroups identifying who responded to the first IPBI include older patients and those presenting with vomiting, whereas male patients responded better to repeat IPBIs.

Abstract
Aim: To study the gastric emptying 30 days after laparoscopic Nissen fundoplication (NF) in gastroesophageal reflux. Materials and Methods: Three patients were evaluated with 13C-acetate breath test (ABT) performed pre and post-NF. The liquid test meal consisted of Racol™ mixed with 13C-acetate. Results: In the patient without neurological impairment (NI), the preoperative t½ex and t lag were 0.900 and 0.510 hours, respectively. The postoperative t½ex and t lag were 0.959 and 0.586 hours, respectively. In one patient with NI, the preoperative t½ex and t lag were 1.828 and 1.092 hours, respectively. The postoperative t½ex and t lag were 2.081 and 1.025 hours, respectively. In the other patient with NI, the preoperative t½ex and t lag were 2.110 and 0.980 hours, respectively. The postoperative t½ex and t lag were 1.118 and 0.415 hours, respectively. Conclusions: Our findings suggest that 13C-ABT parameters did not worsen in any of the children after laparoscopic NF.

Abstract
BACKGROUND/PURPOSES Delayed gastric emptying (DGE) is a cofactor in the etiopathogenesis of gastroesophageal reflux disease (GERD). Scintigraphy is the criterion standard to evaluate gastric emptying (GE). This study aims to define typical scintigraphic activity-time curves (ATCs) related to DGE and esophageal atresia (EA) and to demonstrate the effectiveness of pyloromyotomy (P) in improving GE. METHODS Since 2002, 83 children underwent Nissen fundoplication. Patients were divided into 2 groups: group I, GERD-only patients; group II, patients with GERD owing to EA. Depending on preoperative scintigraphy, each group was subdivided into 2 subgroups. Before surgery and 1 year after, endoscopy and scintigraphy were performed. In the presence of DGE, P was associated with Nissen fundoplication. Gastric emptying differences at baseline and at follow-up were estimated by the Student t test. Pre- and post-ATCs were evaluated by the χ(2) test. RESULTS During follow-up, GE completely normalized in subgroups with DGE. Scintigraphic ATC analysis documented an association between DGE and a typical rectilinear fitting, with a higher rate in EA patients. After P, the scintigraphic pattern changed in an exponential manner related to a faster GE. CONCLUSIONS Delayed gastric emptying is frequent in EA, and the scintigraphic ATCs are typical. Pyloromyotomy is a safe and effective technique to fully normalize GE.

Abstract
In childhood, the surgical treatment of gastroesophageal reflux is the main cause of dumping syndrome. We report the cases of 2 children with esophageal atresia who presented with dumping syndrome without any precipitating known factors, such as gastroesophageal reflux surgery or associated microgastria. Our data suggest (1) that dumping syndrome can occur after primary anastomosis of esophageal atresia without antireflux surgery and (2) that dumping syndrome should be considered in every child treated surgically for esophageal atresia presenting with digestive symptoms, malaise, failure to thrive, or refusal to eat.

Abstract
We evaluated the outcome in infants with esophageal atresia (EA) treated in our department over the last two decades. The medical records of 147 infants treated from 1986 to 2005 were reviewed. Patient characteristics, associated anomalies, surgery and complications were recorded. We divided the material into two time-periods: 1986-1995 and 1996-2005; 125 patients or parents were interviewed regarding gastrointestinal function, respiratory symptoms and education. The incidence of major cardiac defects increased from 23 to 29% and the overall survival increased from 87 to 94%. Using Spitz' classification survival increased from 93.5 to 100% in group I and from 68.4 to 77.8% in group II. In group III, during the second time period, survival was 100% in three patients. The incidence of anastomotic leakage and recurrent fistula did not change over time. The rate of anastomotic strictures increased from 53 to 59% between the two time-periods. A primary anastomosis could be done in 85% of the patients during the second period versus 78% of the patients during the first period. Anti-reflux surgery was done in only 11 and 9%, respectively, during the two time-periods. In patients who were 16-20 years old, 40-50% had gastrointestinal and respiratory symptoms. Ninety percent of the patients attended normal school. The major difference between the periods 1986-1995 and 1996-2005 was an increased survival despite an increased incidence of major cardiac defects. Gastrointestinal and respiratory symptoms were frequent. Long-term follow-up and treatment of complications of esophageal atresia is important for this patient group.

Abstract
Current approaches to the repair of long-gap esophageal atresia (EA) favor esophageal anastomosis. This investigation provides a midterm follow-up of long-gap EA with a primary repair to determine whether this procedure affects symptom severity and whether symptom severity may predict worsening of dysmotility. Fifteen children at least 1-year post primary repair were divided into group 1 (long-gap) and group 2 (non-long-gap). The severity of their symptoms was graded using a questionnaire focused on their eating habits and gastroesophageal motor dysfunction symptoms. Esophageal transit time and gastric emptying were assessed by scintigraphy and used to grade esophagogastric dysmotility. At midterm follow-up the majority of patients in both groups were asymptomatic (66% in group 1 vs 77.7% in group 2; P > 0.05). Esophagogastric dysmotility grades for group 1 were more severe than for group 2 (median 2.5, range from 1 to 4 vs median 1, range from 1 to 2, respectively; P > 0.05). We found no relationship between the severity of the symptoms and the presence or severity of esophagogastric dysmotility. At midterm follow-up in patients with long-gap atresia that underwent primary repair, this study showed scintigraphic evidence of silent and serious esophagogastric dysmotility in symptom-free or minimally symptomatic children. It may therefore be unreliable to use symptoms in assessing the severity of esophagogastric dysmotility, since both groups showed similar clinical findings but different scintigraphic findings.

Abstract
General localization of gastrointestinal bleeding through the use of labeled red blood cells may be performed in children, or (99m)Tc-pertechnetate may be used if a Meckel's diverticulum is suspected. As in adults, cholecystitis and biliary leak may be assessed in children via (99m)Tc-IDA derivatives. Gastroesophageal reflux can be evaluated by oral consumption of the child's usual diet labeled with (99m)Tc sulfur colloid. For the scintigraphic determination of pulmonary aspiration, a relatively high concentration of tracer within a drop of liquid is placed beneath the child's tongue followed by dynamic imaging of the respiratory tract. Colonic transit scintigraphy can aid in the identification and therapeutic decision-making in patients with functional fecal retention, the most common cause of chronic constipation in children. (18)F-DOPA positron emission tomography is useful for classifying pancreatic involvement in infantile hyperinsulinism as focal or diffuse, thereby differentiating between patients who should receive curative focal pancreatic resection versus those who should receive medical management. Assessment of protein-losing enteropathy can be conducted scintigraphically and, compared with fecal alpha-1 antitrypsin collection, the scintigraphic method can detect esophageal and gastric protein loss. Also, scintigraphic quantification of protein loss can be performed without the requirement for fecal collection. Intestinal inflammation in children with inflammatory bowel disease can be evaluated using (99m)Tc white blood cells. The scintigraphic method is safe, accurate, well-tolerated by children and complementary to endoscopy in most patients.

Abstract
The biokinetic and dosimetric model of the gastrointestinal (GI) tract applied in current documents of the International Commission on Radiological Protection (ICRP) was developed in the mid-1960s. The model was based on features of a reference adult male and was first used by the ICRP in Publication 30, Limits for Intakes of Radionuclides by Workers (Part 1, 1979). In the late 1990s an ICRP task group was appointed to develop a biokinetic and dosimetric model of the alimentary tract that reflects updated information and addresses current needs in radiation protection. The new age-specific and gender-specific model, called the Human Alimentary Tract Model (HATM), has been completed and will replace the GI model of Publication 30 in upcoming ICRP documents. This paper discusses the basis for the structure and parameter values of the HATM, summarises the uncertainties associated with selected features and types of predictions of the HATM and examines the sensitivity of dose estimates to these uncertainties for selected radionuclides. Emphasis is on generic biokinetic features of the HATM, particularly transit times through the lumen of the alimentary tract, but key dosimetric features of the model are outlined, and the sensitivity of tissue dose estimates to uncertainties in dosimetric as well as biokinetic features of the HATM are examined for selected radionuclides.

Abstract
OBJECTIVE There is currently no data available in children on possible relationships among Helicobacter pylori, gastric motility and gastric inflammation. This is a prospective study of gastric emptying (GE) in symptomatic children with and without H. pylori who met symptom-based criteria for non-ulcer dyspepsia (NUD). METHODS 47 consecutive dyspeptic patients (23 males; age range, 7 to 18 years) were enrolled. All patients had extensive negative diagnostic investigations. Scintigraphic solid-phase gastric emptying was assessed. RESULTS 21 H. pylori-positive and 26 H. pylori-negative patients were identified with non-ulcer dyspepsia. The groups were not different in clinical symptoms except that pain related to feeding was more frequent in infected children (P < 0.03). Nodular antral gastritis was found more frequently in the H. pylori positive group (P < 0.0001). The gastritis score was more severe in H. pylori infected than H. pylori negative patients in both fundic and body mucosa (P < 0.001). Within the H. pylori-positive NUD group, the mean half-time GE of a solid meal was significantly accelerated compared to the non-infected group (P < 0.05). There was no difference in the intragastric food distribution and curves of gastric emptying of both groups. A significant relationship was found between the degree of gastric body inflammation gastric emptying, but not antral inflammation. Gastric emptying rate did not differ by sex or age of the subjects in either group. CONCLUSIONS In dyspeptic children with H. pylori, gastric emptying of a solid was significantly accelerated compared with symptomatic H. pylori uninfected patients. This suggests that H. pylori is able to induce gastric emptying acceleration. Our findings add more information on H. pylori infection and gastroduodenal disease.

Abstract
PURPOSE The aim of the study was to investigate the gastric smooth muscle reactivity in the Adriamycin-induced esophageal atresia (EA) rat model. METHODS The fetuses were divided into 3 groups. The control group was exposed to saline. The second group was comprised of fetuses that were exposed to Adriamycin but did not have EA (Adriamycin-no-EA group). The third group was comprised of fetuses that were exposed to Adriamycin and had EA (Adriamycin-EA group). Gastric fundus strips were studied in vitro for their contractile response to receptor activation in the 3 groups. RESULTS Contractile responses of gastric smooth muscle to carbachol and KCl were increased in the Adriamycin-EA group compared with the Adriamycin-no-EA group. Also serotonin-induced contractile response in the Adriamycin-EA group decreased compared with the Adriamycin-no-EA group. Relaxation of gastric smooth muscle strips to isoproterenol was comparably unaffected in the Adriamycin-EA and Adriamycin-no-EA groups. Likewise, no change in the response to agonist studies was observed between the control and Adriamycin-no-EA groups. The relaxant response to papaverine was not different in the 3 groups. CONCLUSIONS This study found changes of receptor-dependent and receptor-independent contraction of the gastric fundus smooth muscle in the fetuses with EA. Therefore, impaired contractile responses may be, at least in part, a contributing factor in the abnormal gastric motility seen in EA.

Abstract
Information on the utility of solid-phase gastric emptying studies (SPGES) in the evaluation of children with symptoms of upper gastrointestinal (GI) motor dysfunction is limited. This study was conducted to evaluate the impact of SPGES in the clinical management and outcome of children with upper GI symptoms suggestive of gastroparesis. The records of 45 children who underwent SPGES (31F; 3-17 years) were reviewed. All patients had GI symptoms suggesting gastroparesis. Patients were fed with Tc-99m-sulfur colloid-labeled chicken liver. Adult normal half-life (T1/2) values (F 103 +/- 14 minutes; M 66 +/- 13.6 minutes) were used. The relationships among symptoms, treatment, and outcome were evaluated. Of the 45 patients 9 had delayed, 16 had rapid, and 20 had normal gastric emptying. Six of 9 patients with delayed gastric emptying responded to cisapride. Four of 16 patients with rapid emptying were diagnosed with the dumping syndrome. Of the children with rapid gastric emptying, 87% were females. Twenty patients with normal emptying were diagnosed with gastroesophageal reflux (8), nonulcer dyspepsia (5), irritable bowel syndrome (2), Helicobacter pylori (1), lactose intolerance (1), eosinophilic gastroenteritis (1), duodenitis (1), and constipation (1). In patients who had SPGES for possible gastroparesis, 20% had gastroparesis, 36% had rapid gastric emptying, and 44% had normal gastric emptying. The high number of females in the rapid gastric emptying group might be secondary to normal adult female T1/2 values that were used. The practice of using adult normal T1/2 values in prepubertal girls may need to be revised. Patients with delayed gastric emptying responded to cisapride.

Abstract
BACKGROUND/PURPOSE Disturbed peristalsis is reported frequently after successful repair of esophageal atresia (EA). Delayed gastric emptying could be considered a cause of symptoms of gastroesophageal reflux (GER) in patients with repaired EA. The aim of the current study was to evaluate the incidence of and to characterize gastric motility disorders in a long-term follow-up of patients operated on for EA-tracheoesophageal fistula (TEF) by studying gastric emptying with scintigraphic techniques and comparing the results with gastric manometric data. METHODS Eleven patients, between 12 and 23 years of age (median, 17) operated on for EA-TEF between 1975 and 1985, were studied. The scinthigraphic study was undertaken using a standard solid meal. The manometric study was performed using a 2.3-mm probe with 3 solid-state transducers. RESULTS Dysphagia was present in about 20% of patients. Dyspepsia was recorded in 40% of the patients. A pathological reflux was present in 2 patients. Delayed gastric emptying (T1/2 > 90') was present in 4 patients (36%). Manometric data showed alteration of gastric peristaltic activity in 5 patients (45%). CONCLUSIONS Delayed gastric emptying is frequent in long-term follow-up of patients operated on for EA-TEF. In these patients antral hypomotility also is recorded manometrically. Abnormal gastric motility can be considered as an important factor predisposing to symptoms of GER. A thorough evaluation of gastric function is recommended in symptomatic patients after EA repair.

Abstract
BACKGROUND/PURPOSE Scintigraphy is regarded as the "gold standard" procedure in measuring gastric emptying (GE) rates. 13C-acetate breath test (ABT), which already has been validated in adults, is a noninvasive and nonradioactive alternative method. The aim of the current study was to validate ABT against technetium Tc 99m scintigraphy in children affected by delayed GE. METHODS Sixty children were recruited and divided into 2 groups: group A, 30 healthy controls; group B, 30 patients with gastroesophageal reflux, and scintigraphy-documented DGE (15 neurologically impaired). After an overnight fast, all of them underwent ABT using 25 to 150 mg 13C-acetate. Breath samples were obtained at baseline and then every 10 minutes for 2 hours. The 13CO2 to 12CO2 ratio in breath samples was analysed by isotope ratio mass spectrometry. Data are expressed as follows: time of peak 13C exhalation (tP13CO2b) and half emptying time in ABT (t(1/2b)), and scintigraphy half emptying time (t(1/2s)). RESULTS In controls tP13CO2b was 37 +/- 13 minutes and t(1/2b) 74 +/- 12 minutes. In patients tP13CO2b and t(1/2b) were, respectively, 65 +/- 26 minutes and 104 +/- 18 minutes t(1/2s) was 91 +/- 21 minutes. In group B tP13CO2b and t(1/2b) were delayed significantly compared with controls, respectively, P < .03 and P < .01. In group B significant correlation between t(1/2s) and t(1/2b) was noted (r1 = 0.97). A close correlation was also observed between t(1/2s) and tP13CO2b (r2 = 0.95). CONCLUSION The 13C ABT is an easy, reliable, and less expensive procedure for measuring GE, and its results closely correlate with those of scintigraphy in a paediatric population.
