RESUMO
BACKGROUND: Gastroesophageal reflux disease (GERD) is a common comorbidity associated with congenital diaphragmatic hernia (CDH), with reported cases of Barrett's esophagus (BE) and esophageal adenocarcinoma before the age of 25. The prevalence and natural course of GERD in CDH survivors remain uncertain due to variations in diagnostic methods. We aimed to analyse the GERD prevalence from infancy through young adulthood. METHODS: We retrospectively analyzed pH-impedance measurements and endoscopic findings in 96 CDH survivors evaluated as routine care using well established clinical protocols. GERD was defined as an abnormal acid exposure time for pH-MII measurements and as presence of reflux esophagitis or BE at upper endoscopy. Clinical data including symptoms at time of follow-up and use of antireflux medication were collected. RESULTS: GERD prevalence remained consistently low (≤10%) across all age groups, yet many patients experienced GER symptoms. Histological abnormalities were observed in 80% of adolescents and young adults, including microscopic esophagitis in 50%. BE was diagnosed in 7% before the age of 18, all had GER symptoms. CDH severity, anatomy at the time of CDH correction, alcohol usage, and smoking did not emerge as significant risk factors for GERD. CONCLUSIONS: Given the low GERD prevalence in CDH survivors, a symptom-driven approach to diagnosis and follow-up is warranted. We advise long-term follow-up for all adult patients due to the early onset of BE and the limited evidence available. The longitudinal course and impact of GERD on other long-term CDH-related comorbidities should be explored in larger cohorts. LEVEL OF EVIDENCE: Not applicable.
RESUMO
Extra-intestinal manifestations (EIM) associated with Crohn's disease (CD) are frequently observed and can manifest as either the initial symptom or develop later in the disease course following gastrointestinal symptoms. The most common EIM affect the joints, skin, or eyes, with some correlating with active CD activity while others may occur during periods of inactivity. EIM can affect both pediatric and adult CD patients, potentially reducing their quality of life if not promptly identified and treated. Thus, emphasizing the prevalence and clinical presentation is essential to initiate appropriate diagnostic assessments and effectively treat both EIM and the underlying CD. In this case series, we present two pediatric and one adult case where EIM preceded CD diagnosis, resulting in delayed CD diagnosis. Additionally, we outline the most prevalent EIM, their epidemiology, and associated symptoms.

BACKGROUND: Data on cost-effectiveness of first-line infliximab in paediatric patients with Crohn's disease are limited. Since biologics are increasingly prescribed and accompanied by high costs, this knowledge gap needs to be addressed. AIM: To investigate the cost-effectiveness of first-line infliximab compared to conventional treatment in children with moderate-to-severe Crohn's disease. METHODS: We included patients from the Top-down Infliximab Study in Kids with Crohn's disease randomised controlled trial. Children with newly diagnosed moderate-to-severe Crohn's disease were treated with azathioprine maintenance and either five induction infliximab (biosimilar) infusions or conventional induction treatment (exclusive enteral nutrition or corticosteroids). Direct healthcare consumption and costs were obtained per patient until week 104. This included data on outpatient hospital visits, hospital admissions, drug costs, endoscopies and surgeries. The primary health outcome was the odds ratio of being in clinical remission (weighted paediatric Crohn's disease activity index<12.5) during 104 weeks. RESULTS: We included 89 patients (44 in the first-line infliximab group and 45 in the conventional treatment group). Mean direct healthcare costs per patient were 36,784 for first-line infliximab treatment and 36,874 for conventional treatment over 2 years (p = 0.981). The odds ratio of first-line infliximab versus conventional treatment to be in clinical remission over 104 weeks was 1.56 (95%CI 1.03-2.35, p = 0.036). CONCLUSIONS: First-line infliximab treatment resulted in higher odds of being in clinical remission without being more expensive, making it the dominant strategy over conventional treatment in the first 2 years after diagnosis in children with moderate-to-severe Crohn's disease. TRIAL REGISTRATION NUMBER: NCT02517684.

We present the case of a patient with gross type C esophageal atresia in a preterm neonate (gestational age of 31 weeks + 1 day) with a birth weight of 1,470 g. The fistula was released via a thoracotomy, but no primary anastomosis could be made, due to an unexpected long gap. The distal esophagus was closed and approximated to the blind pouch using traction sutures until an adjacent position was reached. A gastrostomy was created for enteral feeding. Although a second attempt to make an anastomosis was unsuccessful, the patient unexpectedly developed a suture fistula 6 weeks after the first procedure, enabling feeding via a nasogastric tube. Over time, six dilations were necessary. Full enteral feeding was achieved at the age of 6 months. Our case confirms sparse reports that deliberately creating a suture fistula may be a solution in esophageal atresia patients when an unexpected long gap prohibits a primary anastomosis.
RESUMO
INTRODUCTION: Achalasia is a rare neurodegenerative esophageal motility disorder characterized by incomplete lower esophageal sphincter (LES) relaxation, increased LES tone and absence of esophageal peristalsis. Achalasia requires invasive treatment in all patients. Conventional treatment options include endoscopic balloon dilation (EBD) and laparoscopic Heller's myotomy (LHM). Recently, a less invasive endoscopic therapy has been developed; Peroral Endoscopic Myotomy (POEM). POEM integrates the theoretical advantages of both EBD and LHM (no skin incisions, less pain, short hospital stay, less blood loss and a durable myotomy). Our aim is to compare efficacy and safety of POEM vs. EBD as primary treatment for achalasia in children. METHODS AND ANALYSIS: This multi-center, and center-stratified block-randomized controlled trial will assess safety and efficacy of POEM vs EBD. Primary outcome measure is the need for retreatment due to treatment failure (i.e. persisting symptoms (Eckardt score > 3) with evidence of recurrence on barium swallow and/or HRM within 12 months follow-up) as assed by a blinded end-point committee (PROBE design). DISCUSSION: This RCT will be the first one to evaluate which endoscopic therapy is most effective and safe for treatment of naïve pediatric patients with achalasia.

To induce remission in luminal paediatric Crohn's disease (CD), the ESPGHAN/ECCO guideline recommends treatment with exclusive enteral nutrition (EEN) or oral corticosteroids. In newly diagnosed moderate-to-severe paediatric CD patients, we determined the proportion of patients in which EEN or corticosteroids induced remission and maintained remission on azathioprine monotherapy. We included patients from the "TISKids" study assigned to the conventional treatment arm. Patients were aged 3-17 years and had new-onset, untreated luminal CD with weighted paediatric CD activity index (wPCDAI) > 40. Induction treatment consisted of EEN or oral corticosteroids; all received azathioprine maintenance treatment from start of treatment. The primary outcome of this study was endoscopic remission defined as a SES-CD score < 3 without treatment escalation at week 10. Secondary outcomes included proportion of patients without treatment escalation at week 52. In total, 27/47 patients received EEN and 20/47 corticosteroids. At baseline, patient demographics and several inflammation parameters were similar between the two treatment groups. At 10 weeks, clinical remission rates were 7/23 (30%) for EEN and 7/19 (37%) for corticosteroids (p = 0.661). Twenty-nine of 47 consented to endoscopy at 10 weeks, showing endoscopic remission rates without treatment escalation in 2/16 (13%) of EEN-treated patients and in 1/13 (8%) of corticosteroid-treated patients (p = 1.00). At week 52, 23/27 (85%) EEN-treated patients received treatment escalation (median 14 weeks) and 13/20 (65%) corticosteroid-treated patients (median 27 weeks), p = 0.070.Conclusion: In children with moderate-to-severe newly diagnosed CD, induction treatment with EEN or CS regularly is insufficient to achieve endoscopic remission without treatment escalation at week 10. Trial registration number: NCT02517684 What is Known: ⢠Endoscopic remission is associated with a low risk of disease progression. ⢠FL-IFX was superior to conventional treatment in achieving and maintaining remission in paediatric patients with moderate-to-severe CD the first year from diagnosis. What is New: ⢠In children with newly diagnosed moderate-to-severe CD, clinical remission rates and endoscopic remission rates without treatment escalation at week 10 were 30% and 13% after EEN and 37% and 8% after corticosteroid induction treatment. ⢠The current treatment target was often not achieved by either EEN or corticosteroid induction treatment after bridging to azathioprine.

BACKGROUND: In the recent era of growing availability of biological agents, the role of thiopurines needs to be reassessed with the focus on toxicity. AIMS: We assessed the incidence and predictive factors of thiopurine-induced adverse events (AE) resulting in therapy cessation in pediatric inflammatory bowel disease (IBD), related to thiopurine metabolites and biochemical abnormalities, and determined overall drug survival. METHODS: We performed a retrospective, single-center study of children diagnosed with IBD between 2000 and 2019 and treated with thiopurine therapy. The incidence of AE and overall drug survival of thiopurines were evaluated using the Kaplan-Meier method. Correlations between thiopurine metabolites and biochemical tests were computed using Spearman's correlation coefficient. RESULTS: Of 391 patients with IBD, 233 patients (162 Crohn's disease, 62 ulcerative colitis, and 9 IBD-unclassified) were prescribed thiopurines (230 azathioprine and 3 mercaptopurine), of whom 50 patients (22%) discontinued treatment, at least temporary, due to thiopurine-induced AE (median follow-up 20.7 months). Twenty-six patients (52%) were rechallenged and 18 of them (70%) tolerated this. Sixteen patients (6%) switched to a second thiopurine agent after azathioprine intolerance and 10 of them (63%) tolerated this. No predictive factors for development of AE could be identified. Concentrations of 6-thioguanine nucleotides (6-TGN) were significantly correlated with white blood cell and neutrophil count, 6-methylmercaptopurine (6-MMP) concentrations with alanine aminotransferase and gamma-glutamyltranspeptidase. CONCLUSIONS: Approximately 20% of pediatric patients with IBD discontinued thiopurine treatment due to AE. A rechallenge or switch to mercaptopurine is an effective strategy after development of AE. Concentrations of 6-TGN and 6-MMP are associated with biochemical abnormalities.

OBJECTIVE: In newly diagnosed paediatric patients with moderate-to-severe Crohn's disease (CD), infliximab (IFX) is initiated once exclusive enteral nutrition (EEN), corticosteroid and immunomodulator therapies have failed. We aimed to investigate whether starting first-line IFX (FL-IFX) is more effective to achieve and maintain remission than conventional treatment. DESIGN: In this multicentre open-label randomised controlled trial, untreated patients with a new diagnosis of CD (3-17 years old, weighted Paediatric CD Activity Index score (wPCDAI) >40) were assigned to groups that received five infusions of 5 mg/kg IFX at weeks 0, 2, 6, 14 and 22 (FL-IFX), or EEN or oral prednisolone (1 mg/kg, maximum 40 mg) (conventional). The primary outcome was clinical remission on azathioprine, defined as a wPCDAI <12.5 at week 52, without need for treatment escalation, using intention-to-treat analysis. RESULTS: 100 patients were included, 50 in the FL-IFX group and 50 in the conventional group. Four patients did not receive treatment as per protocol. At week 10, a higher proportion of patients in the FL-IFX group than in the conventional group achieved clinical (59% vs 34%, respectively, p=0.021) and endoscopic remission (59% vs 17%, respectively, p=0.001). At week 52, the proportion of patients in clinical remission was not significantly different (p=0.421). However, 19/46 (41%) patients in the FL-IFX group were in clinical remission on azathioprine monotherapy without need for treatment escalation vs 7/48 (15%) in the conventional group (p=0.004). CONCLUSIONS: FL-IFX was superior to conventional treatment in achieving short-term clinical and endoscopic remission, and had greater likelihood of maintaining clinical remission at week 52 on azathioprine monotherapy. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov Registry (NCT02517684).

BACKGROUND: High-resolution esophageal manometry (HREM), derived esophageal pressure topography metrics (EPT), integrated relaxation pressure (IRP), and distal latency (DL) are influenced by age and size. Combined pressure and intraluminal impedance also allow derivation of metrics that define distension pressure and bolus flow timing. We prospectively investigated the effects of esophageal length on these metrics to determine whether adjustment strategies are required for children. METHODS: Fifty-five children (12.3 ± 4.5 years) referred for HREM, and 30 healthy adult volunteers (46.9 ± 3.8 years) were included. Studies were performed using the MMS system and a standardized protocol including 10 × 5 mL thin liquid bolus swallows (SBM kit, Trisco Foods) and analyzed via Swallow Gateway (www.swallowgateway.com). Esophageal distension pressures and swallow latencies were determined in addition to EGJ resting pressure and standard EPT metrics. Effects of esophageal length were examined using partial correlation, correcting for age. Adult-derived upper limits were adjusted for length using the slopes of the identified linear equations. KEY RESULTS: Mean esophageal length in children was 16.8 ± 2.8 cm and correlated significantly with age (r = 0.787, P = .000). Shorter length correlated with higher EGJ resting pressure and 4-s integrated relaxation pressures (IRP), distension pressures, and shorter contraction latencies. Ten patients had an IRP above the adult upper limit. Adjustment for esophageal length reduced the number of patients with elevated IRP to three. CONCLUSIONS & INFERENCES: We prospectively confirmed that certain EPT metrics, as well as potential useful adjunct pressure-impedance measures such as distension pressure, are substantially influenced by esophageal length and require adjusted diagnostic thresholds specifically for children.

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.

OBJECTIVES: Pediatric achalasia is a rare neurodegenerative disorder of the esophagus that requires treatment. Different diagnostic and treatment modalities are available, but there are no data that show how children can best be diagnosed and treated. We aimed to identify current practices regarding the diagnostic and therapeutic approach toward children with achalasia. METHODS: Information on the current practice regarding the management of pediatric achalasia was collected by an online-based survey sent to members of the European and North American Societies for Pediatric Gastroenterology Hepatology and Nutrition involved in pediatric achalasia care. RESULTS: The survey was completed by 38 centers from 24 countries. Within these centers, 108 children were diagnosed with achalasia in the last year (median 2, range 0-15). Achalasia was primarily managed by a pediatric gastroenterologist (76%) and involved a multidisciplinary team in 84% of centers, also including a surgeon (87%), radiologist (61%), dietician (37%), speech pathologist (8%), and psychologist (5%). Medical history taking and physical examination were considered most important to establish the diagnosis (50%), followed by (a combination of) manometry (45%) or contrast swallow (21%). Treatment of first choice was Heller myotomy (58%), followed by pneumatic dilation (46%) and peroral endoscopic myotomy (29%). CONCLUSION: This study shows a great heterogeneity in the management of pediatric achalasia amongst different centers worldwide. These findings stress the need for well-designed intervention trials in children with achalasia. Given the rarity of this disease, we recommend that achalasia care should be managed in centers with access to appropriate diagnostic and treatment modalities.

INTRODUCTION: Achalasia is a rare esophageal motility disorder. Much of the literature is based on the adult population. In adults, guidance of therapeutic approach by manometric findings has led to improvement in patient outcome. Promising results have been achieved with novel therapies such as PerOral Endoscopic Myotomy (POEM). Areas covered: In this review, we provide an overview of the novel diagnostic and therapeutic tools for achalasia management and in what way they will relate to the future management of pediatric achalasia. We performed a PubMed and EMBASE search of English literature on achalasia using the keywords 'children', 'achalasia', 'pneumatic dilation', 'myotomy' and 'POEM'. Cohort studies < 10 cases and studies describing patients ≥ 20 years were excluded. Data regarding patient characteristics, treatment outcome and adverse events were extracted and presented descriptively, or pooled when possible. Expert commentary: Available data report that pneumatic dilation and laparoscopic Heller's myotomy are effective in children, with certain studies suggesting lower success rates in pneumatic dilation. POEM is increasingly used in the pediatric setting with promising short-term results. Gastro-esophageal reflux disease (GERD) may occur post-achalasia intervention due to disruption of the LES and therefore requires diligent follow-up, especially in children treated with POEM.

CONTEXT: Gastroesophageal reflux (GER) is defined as GER disease (GERD) when it leads to troublesome symptoms and/or complications. We hypothesized that definitions and outcome measures in randomized controlled trials (RCTs) on pediatric GERD would be heterogeneous. OBJECTIVES: Systematically assess definitions and outcome measures in RCTs in this population. DATA SOURCES: Data were obtained through Cochrane, Embase, Medline, and Pubmed databases. STUDY SELECTION: We selected English-written therapeutic RCTs concerning GERD in children 0 to 18 years old. DATA EXTRACTION: Data were tabulated and presented descriptively. Each individual parameter or set of parameters with unique criteria for interpretation was considered a single definition for GER(D). Quality was assessed by using the Delphi score. RESULTS: A total of 2410 unique articles were found; 46 articles were included. Twenty-six (57%) studies defined GER by using 25 different definitions and investigated 25 different interventions. GERD was defined in 21 (46%) studies, all using a unique definition and investigating a total of 23 interventions. Respectively 87 and 61 different primary outcome measures were reported by the studies in GER and GERD. Eight (17%) studies did not report on side effects. Of the remaining 38 (83%) studies that did report on side effects, 18 (47%) included this as predefined outcome measure of which 4 (22%) as a primary outcome measure. Sixteen studies (35%) were of good methodological quality. LIMITATIONS: Only English-written studies were included. CONCLUSIONS: Inconsistency and heterogeneity exist in definitions and outcome measures used in RCTs on pediatric GER and GERD; therefore, we recommend the development of a core outcome set.

OBJECTIVES: The Reflux Finding Score for Infants (RFS-I) was developed to assess signs of laryngopharyngeal reflux (LPR) in infants. With flexible laryngoscopy, moderate inter- and highly variable intraobserver reliability was found. We hypothesized that the use of rigid laryngoscopy would increase reliability and therefore evaluated the reliability of the RFS-I for flexible versus rigid laryngoscopy in infants. METHODS: We established a set of videos of consecutively performed flexible and rigid laryngoscopies in infants. The RFS-I was scored twice by 4 otorhinolaryngologists, 2 otorhinolaryngology fellows, and 2 inexperienced observers. Cohen's and Fleiss' kappas (k) were calculated for categorical data and the intraclass correlation coefficient (ICC) was calculated for ordinal data. RESULTS: The study set consisted of laryngoscopic videos of 30 infants (median age 7.5 (0-19.8) months). Overall interobserver reliability of the RFS-I was moderate for both flexible (ICC = 0.60, 95% CI 0.44-0.76) and rigid (ICC = 0.42, 95% CI 0.26-0.62) laryngoscopy. There were no significant differences in reliability of overall RFS-I scores and individual RFS-I items for flexible versus rigid laryngoscopy. Intraobserver reliability of the total RFS-I score ranged from fair to excellent for both flexible (ICC = 0.33-0.93) and rigid (ICC = 0.39-0.86) laryngoscopies. Comparing RFS-I results for flexible versus rigid laryngoscopy per observer, reliability ranged from no to substantial (k = -0.16-0.63, mean k = 0.22), with an observed agreement of 0.08-0.35. CONCLUSION: Reliability of the RFS-I was moderate and did not differ between flexible and rigid laryngoscopies. The RFS-I is not suitable to detect signs or to guide treatment of LPR in infants, neither with flexible nor with rigid laryngoscopy.

BACKGROUND: Gastric volvulus in children is rare and can be life-threatening if not recognised in time. CASE DESCRIPTION: A 3.5-year-old boy presented to his GP with severe, non-bilious vomiting, abdominal distension and abdominal pain. Additional diagnostic tests showed hypochloraemic alkalosis and abdominal ultrasonography suggested gastric volvulus. A barium study showed slow passage of contrast into the duodenum combined with craniomedial displacement of the duodenum. This image matches that of mesenteroaxial gastric volvulus. The diagnosis was confirmed during surgery and gastropexy was successfully performed. CONCLUSION: The diagnosis of gastric volvulus can be difficult. Easily accessible additional diagnostics in the form of ultrasonography, possibly followed by a barium study, may be helpful.

OBJECTIVE: It is hypothesized that laryngeal edema is caused by laryngopharyngeal reflux (LPR) (ie, gastroesophageal reflux extending into the larynx and pharynx). The validated reflux finding score (RFS) assesses LPR disease in adults. We, therefore, aimed to develop an adapted RFS for infants (RFS-I) and assess its observer agreement. STUDY DESIGN: Visibility of laryngeal anatomic landmarks was assessed by determining observer agreement. The RFS-I was developed based on the RFS, the found observer agreement, and expert opinion. An educational tutorial was developed which was presented to 3 pediatric otorhinolaryngologists, 2 otorhinolaryngologists, and 2 gastroenterology fellows. They then scored videos of flexible laryngoscopy procedures of infants who were either diagnosed with or specifically without laryngeal edema. RESULTS: In total, 52 infants were included with a median age of 19.5 (0-70) weeks, with 12 and 40 infants, respectively, for the assessment of the laryngeal anatomic landmarks and the assessment of the RFS-I. Overall interobserver agreement of the RFS-I was moderate (intraclass correlation coefficient = 0.45). Intraobserver agreement ranged from moderate to excellent agreement (intraclass correlation coefficient = 0.50-0.87). CONCLUSION: A standardized scoring instrument was developed for the diagnosis of LPR disease using flexible laryngoscopy. Using this tool, only moderate interobserver agreement was reached with a highly variable intraobserver agreement. Because a valid scoring system for flexible laryngoscopy is lacking up until now, the RFS-I and flexible laryngoscopy should not be used solely to clinically assess LPR related findings of the larynx, nor to guide treatment.

Deglutition, or swallowing, refers to the process of propulsion of a food bolus from the mouth into the stomach and involves the highly coordinated interplay of swallowing and breathing. At 34 weeks gestational age most neonates are capable of successful oral feeding if born at this time; however, the maturation of respiration is still in progress at this stage. Infants can experience congenital and developmental pharyngeal and/or gastrointestinal motility disorders, which might manifest clinically as gastro-oesophageal reflux (GER) symptoms, feeding difficulties and/or refusal, choking episodes and airway changes secondary to micro or overt aspiration. These problems might lead to impaired nutritional intake and failure to thrive. These gastrointestinal motility disorders are mostly classified according to the phase of swallowing in which they occur, that is, the oral preparatory, oral, pharyngeal and oesophageal phases. GER is a common phenomenon in infancy and is referred to as GERD when it causes troublesome complications. GER is predominantly caused by transient relaxation of the lower oesophageal sphincter. In oesophageal atresia, oesophageal motility disorders develop in almost all patients after surgery; however, a congenital origin of disordered motility has also been proposed. This Review highlights the prenatal development of upper gastrointestinal motility and describes the most common motility disorders that occur in early infancy.

OBJECTIVES: Discordance exists between outcomes of endoscopy, multichannel intraluminal impedance monitoring (pH-MII), MII baselines, and gastroesophageal reflux symptoms. The aim of the present study was to determine the association between endoscopy, pH-MII and MII baselines, in children with gastroesophageal reflux symptoms. METHODS: Endoscopies were graded for reflux esophagitis (RE). Biopsies of the distal esophagus were assessed for signs suggestive of esophagitis. Reflux index (RI), symptom association probability (SAP), number of reflux episodes, and mean baseline values were calculated. pH-MII was considered positive in children when RI was ≥ 3% and/or SAP was ≥ 95% and for infants when RI was ≥ 10% and/or SAP was ≥ 95%. Baselines were manually calculated and compared with an automated analysis. For MII baselines, patients were divided in 3 groups: normal endoscopy and negative overall pH-MII; normal endoscopy and an overall positive pH-MII; and RE. RESULTS: A total of 26 children and 14 infants were included, median age: 26.5 months (2 months-16.2 years). Thirteen (32.5%) had RE. A significant negative association was found for RI and MII baselines (P = 0.009) and between SAP and RE (P = 0.039, odds ratio 1.018). MII baseline values were predictive for neither conventional pH-MII parameters nor RE. Manual analysis and automated calculation of MII baselines showed a perfect correlation. Distal MII baselines were significantly lower in children with a positive overall pH-MII outcome compared with the proximal esophagus (P = 0.049). No significant changes were found in baselines among the different groups 1 to 3. CONCLUSIONS: Acid-related parameters are significantly related to MII baselines. A perfect correlation between manual- and automated analysis of MII baselines was found. Large prospective studies are needed to confirm the exact role of endoscopy and MII baselines.

OBJECTIVES: To assess gastroesophageal reflux (GER), esophageal motility, and gastric emptying in children before and after laparoscopic fundoplication and to identify functional measures associated with postoperative dysphagia. STUDY DESIGN: Combined impedance-manometry, 24-hour pH-impedance, and gastric-emptying breath tests were performed before and after laparoscopic anterior partial fundoplication. Impedance-manometry studies were analyzed with the use of conventional analysis methods and a novel automated impedance manometry (AIM) analysis. RESULTS: Children with therapy resistent GER disease (n = 25) were assessed before fundoplication, of whom 10 (median age 6.4 years; range, 1.1-17.1 years; 7 male; 4 with neurologic impairment) underwent fundoplication. GER episodes reduced from 97 (69-172) to 66 (18-87)/24 hours (P = .012). Peristaltic contractions were unaltered. Complete lower esophageal sphincter relaxations decreased after fundoplication (92% [76%-100%] vs 65% [29%-91%], P = .038). Four (40%) patients developed postoperative dysphagia, which was transient in 2. In those patients, preoperative gastric emptying was delayed compared with patients without postoperative dysphagia, 96 minutes (71-104 minutes) versus 48 minutes (26-68 minutes), P = .032, and AIM analysis derived dysphagia risk index was greater (56 [15-105] vs 2 [2-6] P = .016). Two patients underwent a repeat fundoplication. DISCUSSION: Fundoplication in children reduced GER without altering esophageal motility. Four patients who developed dysphagia demonstrated slower gastric emptying and greater dysplasia risk index preoperatively. AIM analysis may allow detection of subtle esophageal abnormalities potentially leading to postoperative dysphagia.
