Do antireflux operations decrease the rate of reflux-related hospitalizations in children?

Management of gastrointestinal and nutritional problems in children on home invasive mechanical ventilation

In recent decades, the patient survival is increased due to advances in intensive care units and development of modern mechanic ventilators. Unfortunately, it is not always possible to wean these children from mechanical ventilation. Recently, after placement a tracheostomy tube, these children can be supported at home with noninvasive or invasive mechanical ventilation. Most of the children who need ventilation support at home have neurological impairment. The nutritional issues and gastrointestinal (GI) complications are well defined in critically ill patients, but there are very limited studies on children with tracheostomy. Considering that majority of the patients have neuromuscular disorders, the nutritional and GI problems of the children with tracheostomy are discussed in light of the knowledge of critically ill patients.

Gastroesophageal Reflux Treatment in Infancy Through Young Adulthood

Gastroesophageal reflux treatment varies greatly across the pediatric age spectrum. Infant reflux treatments rely heavily on nutritional interventions, whereas reflux in older children is treated more commonly with medications. However, because of the broad differential diagnosis, treatment nonresponse merits a re-evaluation of the diagnosis being treated and additional testing to provide a more precision-medicine approach to care.

Gastro-oesophageal reflux disease

Gastro-oesophageal reflux disease (GERD) is a common disorder in adults and children. The global prevalence of GERD is high and increasing. Non-erosive reflux disease is the most common phenotype of GERD. Heartburn and regurgitation are considered classic symptoms but GERD may present with various atypical and extra-oesophageal manifestations. The pathophysiology of GERD is multifactorial and different mechanisms may result in GERD symptoms, including gastric composition and motility, anti-reflux barrier, refluxate characteristics, clearance mechanisms, mucosal integrity and symptom perception. In clinical practice, the diagnosis of GERD is commonly established on the basis of response to anti-reflux treatment; however, a more accurate diagnosis requires testing that includes upper gastrointestinal tract endoscopy and reflux monitoring. New techniques and new reflux testing parameters help to better phenotype the condition. In children, the diagnosis of GERD is primarily based on history and physical examination and treatment vary with age. Treatment in adults includes a combination of lifestyle modifications with pharmacological, endoscopic or surgical intervention. In refractory GERD, optimization of proton-pump inhibitor treatment should be attempted before a series of diagnostic tests to assess the patient's phenotype.

Trends in gastrostomy tube placement with concomitant Nissen fundoplication for infants and young children at Pediatric Tertiary Centers

PURPOSE

In infants and toddlers, gastrostomy tube placement (GT) is typically accompanied by consideration of concomitant Nissen fundoplication (NF). Historically, rates of NF have varied across providers and institutions. This study examines practice variation and longitudinal trends in NF at pediatric tertiary centers.

METHODS

Patients ≤ 2 years who underwent GT between 2008 and 2018 were identified in the Pediatric Health Information System database. Patient demographics and rates of NF were examined. Descriptive statistics were used to evaluate the variation in the proportion of GT with NF at each hospital, by volume and over time.

RESULTS

40,348 patients were identified across 40 hospitals. Most patients were male (53.8%), non-Hispanic white (49.5%) and publicly-insured (60.4%). Rates of NF by hospital varied significantly from 4.2 to 75.2% (p < 0.001), though were not associated with geographic region (p = 0.088). Rates of NF decreased from 42.8% in 2008 to 14.2% in 2018, with a mean annual rate of change of - 3.07% (95% CI - 3.53, - 2.61). This trend remained when stratifying hospitals into volume quartiles.

CONCLUSION

There is significant practice variation in performing NF. Regardless of volume, the rate of NF is also decreasing. Objective NF outcome measurements are needed to standardize the management of long-term enteral access in this population.

Long-Term Analysis of Respiratory-Related Complications Following Gastrostomy Placement with or without Fundoplication in Neurologically Impaired Children: A Retrospective Cohort Study

Gastrostomy placement is crucial in neurologically impaired (NI) children to ensure an adequate food intake and a safe route for drugs administration and to reduce the risk of primary aspiration. NI patents are more prone to gastroesophageal reflux. The association with fundoplication is deemed to reduce reflux-related respiratory complications. However, long-term benefits of this approach are not clear. We therefore aimed to compare long-term reflux-related respiratory complications of gastrostomy only (GO) to gastrostomy with fundoplication (GF). We retrospectively reviewed 145 consecutive NI children managed from 2008 to 2018. As long-term outcomes, we analyzed number and length of hospital admissions (Reflux-Related-Hospitalization, RRH) and emergency department accesses (Reflux-Related-Accesses, RRA) due to respiratory problems. Results were analyzed with appropriate statistical method. Median age at referral and at gastrostomy placement were 2.2 and 3.4 years (SD 5.6), respectively. Median follow-up was four years (range 1-12). Anti-reflux procedures were performed in 26/145 patients (18%); tracheotomy in 23/145 (16%). RRH following surgery showed lower number of admissions/year (0.32 vs. 1 for GO vs. GF, p < 0.005) and days hospitalization/year (3 vs. 13, p = 0.08) in GO compared to GF; RRA was similar (0.60 vs. 0.65, p = 0.43). Gastrostomy placement alone appeared not to be inferior to gastrostomy plus fundoplication with respect to long-term respiratory-related outcomes for NI children in our center.

Standardized pathway for feeding tube placement reduces unnecessary surgery and improves value of care

BACKGROUND

Children requiring gastrostomy tubes (GT) have high resource utilization. In addition, wide variation exists in the decision to perform concurrent fundoplication, which can increase the morbidity of enteral access surgery. We implemented a hospital-wide standardized pathway for GT placement.

METHODS

The standardized pathway included mandatory preoperative nasogastric feeding tube (FT) trial, identification of FT medical home, and standardized postoperative order set, including feeding regimen and parent education. An algorithm to determine whether concurrent fundoplication was indicated was also created. We identified children referred for GT placement from 2015 to 2018 and compared concurrent fundoplication rates and outcomes pre- and postimplementation.

RESULTS

We identified 332 patients who were referred for GT. Of these, 15 avoided placement. Concurrent fundoplication decreased postpathway (48% vs 22%, p < 0.0001). After adjusting for reflux and cardiac disease, prepathway patients were 3.5 times more likely to undergo concurrent fundoplication. ED visits (46% vs 27%, p = 0.001) and postoperative LOS (median (IQR) 10 days (5-36) to 5.5 days (1-19), p = 0.0002) decreased.

CONCLUSIONS

A standardized pathway for GT placement prevented unnecessary GT placement and fundoplication with reduction in postoperative LOS and ED visits. This approach can significantly reduce resource utilization while improving outcomes.

Aerodigestive sampling reveals altered microbial exchange between lung, oropharyngeal, and gastric microbiomes in children with impaired swallow function

BACKGROUND

Children with oropharyngeal dysphagia have impaired airway protection mechanisms and are at higher risk for pneumonia and other pulmonary complications. Aspiration of gastric contents is often implicated as a cause for these pulmonary complications, despite being supported by little evidence. The goal of this study is to determine the relative contribution of oropharyngeal and gastric microbial communities to perturbations in the lung microbiome of children with and without oropharyngeal dysphagia and aspiration.

METHODS

We conducted a prospective cohort study of 220 patients consecutively recruited from a tertiary aerodigestive center undergoing simultaneous esophagogastroduodenoscopy and flexible bronchoscopy. Bronchoalveolar lavage, gastric and oropharyngeal samples were collected from all recruited patients and 16S sequencing was performed. A subset of 104 patients also underwent video fluoroscopic swallow studies to assess swallow function and were categorized as aspiration/no aspiration. To ensure the validity of the results, we compared the microbiome of these aerodigestive patients to the microbiome of pediatric patients recruited to a longitudinal cohort study of children with suspected GERD; patients recruited to this study had oropharyngeal, gastric and/or stool samples available. The relationships between microbial communities across the aerodigestive tract were described by analyzing within- and between-patient beta diversities and identifying taxa which are exchanged between aerodigestive sites within patients. These relationships were then compared in patients with and without aspiration to evaluate the effect of aspiration on the aerodigestive microbiome.

RESULTS

Within all patients, lung, oropharyngeal and gastric microbiomes overlap. The degree of similarity is the lowest between the oropharynx and lungs (median Jensen-Shannon distance (JSD) = 0.90), and as high between the stomach and lungs as between the oropharynx and stomach (median JSD = 0.56 for both; p = 0.6). Unlike the oropharyngeal microbiome, lung and gastric communities are highly variable across people and driven primarily by person rather than body site. In patients with aspiration, the lung microbiome more closely resembles oropharyngeal rather than gastric communities and there is greater prevalence of microbial exchange between the lung and oropharynx than between gastric and lung sites (p = 0.04 and 4x10-5, respectively).

CONCLUSIONS

The gastric and lung microbiomes display significant overlap in patients with intact airway protective mechanisms while the lung and oropharynx remain distinct. In patients with impaired swallow function and aspiration, the lung microbiome shifts towards oropharyngeal rather than gastric communities. This finding may explain why antireflux surgeries fail to show benefit in pediatric pulmonary outcomes.

Predictors of multiple readmissions or death in the first year after Nissen fundoplication in children

PURPOSE

Nissen fundoplication (NF) is commonly performed in children with gastro-esophageal reflux disease (GERD). Patients undergoing NF often have co-morbidities. Reported outcomes of NF vary considerably. This study investigated which factors might predict multiple readmissions or death in the first year following NF at our institution.

METHODS

A retrospective chart review of 187 children who underwent NF at our institution between January 2004 and December 2015 was undertaken. Underlying medical conditions, age, weight, presence of malnutrition, length of hospital stay prior to surgery and type of surgery were recorded. Patients who had more than one admission in the first post-operative year were compared to those who had one or none, and patients who died within the first post-operative year were compared to those who did not.

RESULTS

Risk factors for multiple readmissions were underlying cardiac disease (p = 0.011), esophageal atresia (EA) (p = 0.011), and esophageal stricture (p = 0.0002). Risk factors for death included younger age (p = 0.028), need for gastrostomy tube (GT) (p = 0.01) and prolonged pre-operative hospital admission (p = 0.0003).

CONCLUSION

This study identified multiple factors associated with readmission and death in the first year after NF. These findings will help with the counseling patients and caregivers regarding expectations following NF.

Survival and Health Care Use After Feeding Tube Placement in Children With Neurologic Impairment

BACKGROUND AND OBJECTIVES

Children with neurologic impairment (NI) often undergo feeding tube placement for undernutrition or aspiration. We evaluated survival and acute health care use after tube placement in this population.

METHODS

This is a population-based exposure-crossover study for which we use linked administrative data from Ontario, Canada. We identified children aged 13 months to 17 years with a diagnosis of NI undergoing primary gastrostomy or gastrojejunostomy tube placement between 1993 and 2015. We determined survival time from procedure until date of death or last clinical encounter and calculated mean weekly rates of unplanned hospital days overall and for reflux-related diagnoses, emergency department visits, and outpatient visits. Rate ratios were estimated from negative binomial generalized estimating equation models adjusting for time and age.

RESULTS

Two-year survival after feeding tube placement was 87.4% (95% confidence interval [CI]: 85.2%-89.4%) and 5-year survival was 75.8% (95% CI: 72.8%-78.4%). The adjusted rate ratio comparing weekly rates of unplanned hospital days during the 2 years after versus before tube placement was 0.92 (95% CI: 0.57-1.48). Similarly, rates of reflux-related hospital days, emergency department visits, and outpatient visits were unchanged. Unplanned hospital days were stable within subgroups, although rates across subgroups varied.

CONCLUSIONS

Mortality is high among children with NI after feeding tube placement. However, the stability of health care use before and after the procedure suggests that the high mortality may reflect underlying fragility rather than increased risk from nonoral feeding. Further research to inform risk stratification and prognostic accuracy is needed.

Analysis of Growth, Nutritional Status and Hospital Visitation Scores Associated with Reflux After Nissen Fundoplication in Neurologically Impaired Children with Gastroesophageal Reflux

BACKGROUND

Neurologically impaired children (NIC) often experience swallowing difficulties and gastroesophageal reflux disease (GERD). Although these conditions could place children in a state of poor nutritional status and prevent them from thriving, there is insufficient research evaluating growth and nutritional status following fundoplication in these patients.

METHOD

This is a retrospective study of patients who were neurologically impaired and underwent Nissen fundoplication between April 2001 and March 2015. Seventy-six patients were enrolled, and the follow-up period was 12 months or longer. Growth was measured by the change in body weight and height. Nutritional status was measured by the change in body mass index, serum albumin and protein level.

RESULTS

Median age at operation was 1.85 years old, and median body weight was 10 kg. The respective Z scores for weight and height showed significant improvements after 1 year since the operation compared to 1 year within the operation (-2.42 ± 2.19 vs. -1.31 ± 1.96, P < 0.001) (-1.6 ± 2.16 vs. -1.05 ± 1.69, P = 0.002). The respective Z scores for body mass index, albumin and protein also showed improvements after 1 year since the operation compared to 1 year within the operation (-2.07 ± 2.99 vs. -0.89 ± 2.1, P < 0.001) (3.55 ± 0.48 vs. 3.86 ± 0.45, P < 0.001) (6.22 ± 0.76 vs. 6.65 ± 0.51, P < 0.001). Hospital visitation scores associated with reflux were significantly lower after the operation (4.1 ± 3.43 vs. 1.18 ± 1.67, P < 0.001).

CONCLUSIONS

In summary, after Nissen fundoplication in NIC with GER, growth and nutritional status improved significantly. Also, hospital visitation scores associated with reflux decreased after the operation.

Gastrointestinal and nutritional issues in children with neurological disability

Neurological disability is often associated with feeding and gastrointestinal disorders leading to malnutrition and growth failure. Assessment of nutritional status represents the first step in the clinical evaluation of children with neurological disability. The European Society of Gastroenterology, Hepatology, and Nutrition (ESPGHAN) recently issued a consensus statement on gastrointestinal and nutritional management in children with neurological disability. Here we critically review and address implications of this consensus for clinical practice, including assessment and monitoring of nutritional status, definition of nutritional requirements, diagnosis and treatment of gastro-oesophageal reflux disease, and indications for and modalities of nutritional support. There is a strong evidence base supporting the ESPGHAN guidelines; their application is expected to lead to better management of this group of children.

WHAT THIS PAPER ADDS

Assessment of nutritional status in children with neurological disability should include the evaluation of body composition. Standard polymeric formula via gastrostomy tube is an effective, long-term nutritional intervention. Tube feeding should be started early, before the development of malnutrition.

Pediatric Gastroesophageal Reflux Clinical Practice Guidelines: Joint Recommendations of the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition and the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition

This document serves as an update of the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition (NASPGHAN) and the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) 2009 clinical guidelines for the diagnosis and management of gastroesophageal reflux disease (GERD) in infants and children and is intended to be applied in daily practice and as a basis for clinical trials. Eight clinical questions addressing diagnostic, therapeutic and prognostic topics were formulated. A systematic literature search was performed from October 1, 2008 (if the question was addressed by 2009 guidelines) or from inception to June 1, 2015 using Embase, MEDLINE, the Cochrane Database of Systematic Reviews and the Cochrane Central Register of Controlled Clinical Trials. The approach of the Grading of Recommendations Assessment, Development and Evaluation (GRADE) was applied to define and prioritize outcomes. For therapeutic questions, the quality of evidence was also assessed using GRADE. Grading the quality of evidence for other questions was performed according to the Quality Assessment of Studies of Diagnostic Accuracy (QUADAS) and Quality in Prognostic Studies (QUIPS) tools. During a 3-day consensus meeting, all recommendations were discussed and finalized. In cases where no randomized controlled trials (RCT; therapeutic questions) or diagnostic accuracy studies were available to support the recommendations, expert opinion was used. The group members voted on each recommendation, using the nominal voting technique. With this approach, recommendations regarding evaluation and management of infants and children with GERD to standardize and improve quality of care were formulated. Additionally, 2 algorithms were developed, 1 for infants <12 months of age and the other for older infants and children.

Laparoscopic Nissen Fundoplication: An Excellent Treatment of GERD-Related Respiratory Symptoms in Children-Results of a Multicentric Study

INTRODUCTION

Respiratory manifestations of gastroesophageal reflux disease (GERD), particularly chronic cough, are being recognized with increased frequency in children. This survey aimed to investigate the efficacy of laparoscopic Nissen fundoplication for treatment of GERD-related respiratory symptoms not responsive to medical therapy in neurological normal children.

MATERIALS AND METHODS

We collected data of children with GERD-related respiratory complaints not responsive to medical therapy who underwent laparoscopic Nissen fundoplication in four European centers of Pediatric Surgery over a 10-year period. We excluded children with neurological impairment.

RESULTS

A total of 220 laparoscopic Nissen procedures were performed in the period 2005-2015. Twenty-four (12 boys and 12 girls, average age 9.5 years) out of the 220 patients (10.9%) presented with chronic cough and other respiratory manifestations, including asthma, reactive airway disease, and recurrent pneumonia. Average operative time was 65 minutes (range 45-100). As for postoperative complications, two tight wraps requiring endoscopic dilatation (IIIb Clavien) and two relapses of GERD for slipped Nissen requiring reoperation (IIIb Clavien) were recorded. None of these complications occurred in the group of patients with GERD-related respiratory symptoms. At follow-up evaluation, respiratory symptoms disappeared with a significant improvement of quality of life scoring (I Grade Visick) in 22/24 patients (91.6%).

CONCLUSION

Our results confirm that GERD should be investigated as one of the possible etiologic factors in any child with persistent respiratory complaints. In patients with symptoms not responsive to medical therapy, laparoscopic Nissen fundoplication is the treatment of choice with a very high success rate (>90% in our series), a very low morbidity, a significant improvement in airway symptoms, and a marked reduction in the need for medications.

Parents reported reduced symptoms and improved satisfaction after fundoplication and their perceptions were an important outcome measure

AIM

Fundoplication is required for children with chronic recurrent gastro-oesophageal reflux disease (GERD). The aim of this study was to report parental perceptions of symptoms and overall satisfaction with the long-term course following fundoplication with special reference to patients with GERD risk factors.

METHODS

We studied 34 patients, with a median age of 6.5 ± 4.9 years, who received fundoplication between 2001 and 2005. Clinical information and surgical complications were recorded. Parents were interviewed to evaluate post-operative symptoms, mode of nutrition and satisfaction.

RESULTS

The median follow-up time was 7.3 years. Comorbidities were neurological impairment in 15 patients, other gastrointestinal disorders in seven patients and isolated GERD in 12 patients. The parents reported that fundoplication effectively treated initial reflux symptoms in 60% and improved symptoms in 37%. Vomiting and reflux-associated pain were treated most effectively. Pulmonary symptoms often remained unchanged in neurologically impaired children. Redo fundoplication was necessary in seven patients. Only two parents regretted consenting to surgery.

CONCLUSION

A high percentage of parents reported improved gastrointestinal reflux-related symptoms and a high level of satisfaction following fundoplication. Parental perceptions of GERD symptoms should be an important outcome measure when assessing the efficacy of antireflux surgery in children in routine clinical follow-up.

ESPGHAN-NASPGHAN Guidelines for the Evaluation and Treatment of Gastrointestinal and Nutritional Complications in Children With Esophageal Atresia-Tracheoesophageal Fistula

BACKGROUND

Esophageal atresia (EA) is one of the most common congenital digestive anomalies. With improvements in surgical techniques and intensive care treatments, the focus of care of these patients has shifted from mortality to morbidity and quality-of-life issues. These children face gastrointestinal (GI) problems not only in early childhood but also through adolescence and adulthood. There is, however, currently a lack of a systematic approach to the care of these patients. The GI working group of International Network on Esophageal Atresia comprises members from ESPGHAN/NASPGHAN and was charged with the task of developing uniform evidence-based guidelines for the management of GI complications in children with EA.

METHODS

Thirty-six clinical questions addressing the diagnosis, treatment, and prognosis of the common GI complications in patients with EA were formulated. Questions on the diagnosis, and treatment of gastroesophageal reflux, management of "cyanotic spells," etiology, investigation and management of dysphagia, feeding difficulties, anastomotic strictures, congenital esophageal stenosis in EA patients were addressed. The importance of excluding eosinophilic esophagitis and associated GI anomalies in symptomatic patients with EA is discussed as is the quality of life of these patients and the importance of a systematic transition of care to adulthood. A systematic literature search was performed from inception to March 2014 using Embase, MEDLINE, the Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Clinical Trials, and PsychInfo databases. The approach of the Grading of Recommendations Assessment, Development and Evaluation was applied to evaluate outcomes. During 2 consensus meetings, all recommendations were discussed and finalized. The group members voted on each recommendation, using the nominal voting technique. Expert opinion was used where no randomized controlled trials were available to support the recommendation.

Gastroesophageal reflux disease in children

Despite the frequency with which antireflux procedures are performed, decisions about gastroesophageal reflux disease treatment remain challenging. Several factors contribute to the difficulties in managing gastroesophageal reflux. First, the distinction between physiologic and pathologic gastroesophageal reflux (gastroesophageal reflux disease-GERD) is not always clear. Second, measures of the extent of gastroesophageal reflux often poorly correlate to symptoms or other complications attributed to reflux in infants and children. A third challenge is that the outcome of antireflux procedures, predominately fundoplications, are relatively poorly characterized. All of these factors contribute to difficulty in knowing when to recommend antireflux surgery. One of the manifestations of the uncertainties surrounding GERD is the high degree of variability in the utilization of pediatric antireflux procedures throughout the United States. Pediatric surgeons are frequently consulted for GERD and fundoplication, uncertainties notwithstanding. Although retrospective series and anecdotal observations support fundoplication in some patients, there are many important questions for which sufficient high-quality data to provide a clear answer is lacking. In spite of this, surgeons need to provide guidance to patients and families while awaiting the development of improved evidence to aid in these recommendations. The purpose of this article is to define what is known and what is uncertain, with an emphasis on the most recent evidence.

Gastroesophageal Reflux Burden, Even in Children That Aspirate, Does Not Increase Pediatric Hospitalization

OBJECTIVES

Gastroesophageal reflux is common but remains a controversial disease to diagnose and treat and little is known about the role of reflux testing in predicting clinical outcomes, particularly in children at risk for extraesophageal reflux complications. The aim of this study was to determine if rates of hospitalization were affected by reflux burden even after adjusting for aspiration risk.

METHODS

We prospectively recruited, between 2009 and 2014, a cohort of pediatric patients with suspected extraesophageal reflux disease who were referred for reflux testing and underwent both multichannel intraluminal impedance with pH (pH-MII) and modified barium swallow studies. A subset of patients also underwent bronchoalveolar lavage with pepsin analysis. We determined their rates of hospitalization for a minimum of 1 year following pH-MII testing.

RESULTS

We prospectively enrolled 116 pediatric patients who presented for care at Boston Children's Hospital and underwent both pH-MII and modified barium swallow studies. There was no statistically significant relationship between reflux burden measured by pH-MII or bronchoalveolar pepsin and total number of admissions or number of admission nights even after adjusting for aspiration status (P > 0.2). There were no statistically significant relationships between reflux burden by any method and the number or nights of urgent pulmonary admissions before or after adjusting for aspiration risk (P > 0.08).

CONCLUSIONS

Even in aspirating children, reflux burden did not increase the risk of hospitalization. Based on these results, routine reflux testing cannot be recommended even in aspirating children, because the results do not impact clinically significant outcomes.

Feeding Difficulties in Children with Esophageal Atresia

The current available literature evaluating feeding difficulties in children with esophageal atresia was reviewed. The published literature was searched through PubMed using a pre-defined search strategy. Feeding difficulties are commonly encountered in children and adults with repaired esophageal atresia [EA]. The mechanism for abnormal feeding includes both esophageal and oropharyngeal dysphagia. Esophageal dysphagia is commonly reported in patients with EA and causes include dysmotility, anatomic lesions, esophageal outlet obstruction and esophageal inflammation. Endoscopic evaluation, esophageal manometry and esophograms can be useful studies to evaluate for causes of esophageal dysphagia. Oropharyngeal dysfunction and aspiration are also important mechanisms for feeding difficulties in patients with EA. These patients often present with respiratory symptoms. Videofluoroscopic swallow study, salivagram, fiberoptic endoscopic evaluation of swallowing and high-resolution manometry can all be helpful tools to identify aspiration. Once diagnosed, management goals include reduction of aspiration during swallowing, reducing full column reflux into the oropharynx and continuation of oral feeding to maintain skills. We review specific strategies which can be used to reduce aspiration of gastric contents, including thickening feeds, changing feeding schedule, switching formula, trialing transpyloric feeds and fundoplication.

Clinical management of post-pyloric enteral feeding in children

Post-pyloric feeding (PF) allows the administration of enteral nutrition beyond the pylorus, either into the duodenum or, ideally, into the jejunum. The main indications of PF are: upper gastrointestinal tract obstructions, pancreatic rest (e.g., acute pancreatitis), gastric dysmotility (e.g., critically ill patients and chronic intestinal pseudo-obstruction) or severe gastroesophageal reflux with risk of aspiration (e.g., neurological disability). Physiological and clinical evidence derives from adults, but can also be pertinent to children. This review will discuss the practical management and potential clinical applications of PF in pediatric patients. Some key studies pertaining to the physiological changes during PF will also be considered because they support the strategy of PF management.

Long-term effects of fundoplication in children with chronic airway diseases

BACKGROUND

Association between chronic airway diseases (CAD) and gastroesophageal reflux disease (GERD) is well described, but causality has not yet been conclusively established. This study evaluates the therapeutic significance of laparoscopic Thal fundoplication in children with CAD and diagnosed GERD.

METHODS

We performed a retrospective analysis of 182 neurologically nonimpaired children, all with medically refractory CAD and GERD undergoing laparoscopic Thal fundoplication. The clinical response, ability to wean oral and inhaled medication and satisfaction with postoperative results were evaluated.

RESULTS

Main symptoms disappeared completely in 68.7% of patients and were markedly improved in a further 22% of patients following surgery. Complete discontinuation of medication was achieved in 70.1-96.4% of cases and reduced in a further 1.8-23.5%. One intraoperative complication occurred (gastric perforation), however no conversion to laparotomy was necessary. Postoperative Dumping Syndrome occurred in 1% of cases and was managed dietetically. Prolonged postoperative dysphagia occurred in 4.3% of patients, but disappeared within 8 weeks in all but one case.

CONCLUSIONS

Our study suggests that Thal fundoplication in neurologically nonimpaired children with CAD and documented GERD is effective and safe. Children unresponsive to preoperative medical management showed significant improvement in airway symptoms together with a marked reduction in the need for medication. We conclude that laparoscopic Thal fundoplication represents a significant treatment worthy of consideration in this group of patients.

Mewling and puking: infantile gastroesophageal reflux in the 21st century

Infantile gastroesophageal reflux is challenging because of the difficulties in differentiating normal developmental physiology from disease, the imprecision of diagnostic tests and the paucity of evidence-based therapies for clinicians to implement. Careful clinical assessment is central to avoidance of inappropriate diagnosis and utilisation of ineffective or dangerous therapies, and at the same time, identification of those infants who warrant intervention.

Reflux aspiration in children with neurodisability--a significant problem, but can we measure it?

Recurrent respiratory problems are common in children with severe neurodisability, and respiratory deterioration is a leading cause of premature death in this group. Although the etiology is multifactorial, recurrent pulmonary aspiration is thought to play a significant role. Gastroesophageal reflux is known to be common, as is oral-motor discoordination. Differentiating direct aspiration of food and saliva and gastric reflux aspiration is difficult and presents a challenge in managing patients and assessing their suitability for surgical antireflux procedures. This is particularly the case when children present with predominantly respiratory symptoms, where there may be direct aspiration, reflux aspiration, neither, or both. A clinical biomarker to identify and quantify reflux aspiration would therefore be useful in surgical assessment and may also be applicable as an outcome measure for clinical trials of antireflux surgery. In this review, we discuss the evidence base behind existing and potentially novel biomarkers of aspiration in bronchoalveolar lavage fluid. We highlight the limitations of the lipid-laden macrophage index, particularly with regard to its specificity and interrater/intrarater reliability. We discuss the laboratory methods available to measure promising new biomarkers (pepsin and bile acids) and highlight their potential advantages and disadvantages. Finally, to understand how aspiration causes clinical signs and symptoms in our patients, we need to study the effect of aspirated substances on the lung, and here we review the available in vivo and in vitro literature.

Well-being of children with neurologic impairment after fundoplication and gastrojejunostomy tube feeding

BACKGROUND

There is limited understanding on the impact of fundoplication or gastrojejunostomy tube (GJT) feeding in children with neurologic impairment who have swallowing dysfunction, gastroesophageal reflux disease, and/or dysmotility.

OBJECTIVE

To explore and understand the well-being of families and their children with neurologic impairment who had either a fundoplication or GJT.

METHODS

This was a qualitative study using in-depth, individual interviews with parents of children with severe neurologic impairment who had either a fundoplication with gastrostomy or GJT. Parents' perceptions of daily life and QoL were explored in the context of the interventions. Interviews were transcribed, and data were analyzed using qualitative content analysis.

RESULTS

Children and their parents are profoundly impacted by the health condition of the children. QoL effects were similar across spheres of individual and family experience and well-being. Themes related to QoL were: physical health of the child and the future, intense caregiving needs, social isolation and stigma, pervasive impact on the family, financial strain, and the process of finding meaning. Fundoplication and GJT affected feeding tolerance and times, caregiving, and health care utilization. Parents identified how changes in these factors influenced child, parental, and family QoL.

CONCLUSIONS

The diverse influences of the underlying condition and the interventions should be addressed in the delivery of health services. Future studies of the effectiveness of fundoplication and GJT feeding should address the well-being of the child and family, the impact on family caregiving, and health care utilization.

Short- and long-term antireflux and asthma medication use in children after nissen fundoplication

PURPOSE

We sought to determine antireflux and asthma medication use after Nissen fundoplication (NF).

METHODS

We performed a retrospective study using hospital discharge and pharmacy data from 1996 through 2005. A total of 342 pediatric patients had ≥1 NF; 336 of those had complete medication data. Use of antireflux medications and asthma medications were reviewed before and after NF.

RESULTS

Short-term (one year after NF) use of antireflux medications decreased (odds ratio [OR] = 0.35; 95% confidence interval [CI], 0.26-0.45). During the entire study period, the decrease in antireflux medication use after NF remained in place (233 to 197 patients; OR = 0.63; 95% CI, 0.47-0.84). Use of antireflux medications decreased in neurologically healthy patients (n = 186) after NF but remained the same in neurologically impaired patients. Short-term use of inhaled and systemic asthma medications did not change (OR = 1.16 [95% CI, 0.89-1.51] and 0.90 [95% CI, 0.69-1.18]), respectively. During the entire study period, inhaled and systemic asthma medication use increased after NF (OR = 2.11 [95% CI, 1.63-2.74] and 1.85 [95% CI, 1.43-2.41]), respectively. Inhaled and systemic asthma medication use increased in both neurologically healthy and impaired children. In older children (age >5 years), short-term use of inhaled and systemic asthma medications decreased after NF (OR = 0.39 [95% CI, 0.25-0.60] and 0.31 [95% CI, 0.19-0.53]), respectively. However, during the entire study period, inhaled and systemic asthma medication use in older children remained the same.

CONCLUSION

NF decreased antireflux medication use in the short and long term, particularly in neurologically healthy children. Inhaled and systemic asthma medication use increased after NF in neurologically healthy and impaired children. NF provided a short-term decrease in inhaled and systemic asthma medication use in older children but showed no change in the long term.

Laryngotracheal separation surgery for intractable aspiration: our experience with 12 patients

OBJECTIVE

Laryngotracheal separation surgery (LTS) was performed as a treatment for recurrent or intractable aspiration pneumonia in 12 pediatric patients. The effectiveness of LTS surgery for preventing aspiration pneumonia, and the complications of this procedure were investigated.

METHODS

A retrospective chart review, conducted at a tertiary academic hospital in conjunction with a private practice, was used to identify children who underwent Laryngotracheal Separation Surgery (LTS) from September 2001 to July 2007. The main outcome measure was the number of hospital admissions for pneumonia in the pre LTS and post LTS period. A student's t-test was used for statistical analysis.

RESULTS

LTS surgery decreased the frequency of pulmonary infections and respiratory events in all patients, resulting in far fewer hospitalizations. These patients experienced an average of 5 hospital admissions for pneumonia in the 2 years prior to LTS surgery, and an average of 1.1 hospital admissions for pneumonia after the LTS surgery. There were no major complications related to the surgery. Several minor complications following surgery were easily and effectively dealt with in the perioperative period.

CONCLUSIONS

LTS surgery is an effective and safe procedure in children with intractable aspiration. Parents do not perceive the care of the LTS stoma as burdensome. This procedure should be considered as an option in the surgical intervention for the management of chronic aspiration pneumonia in severely neurologically impaired children.

Variations in preoperative decision making for antireflux procedures in pediatric gastroesophageal reflux disease: a survey of pediatric surgeons

BACKGROUND/PURPOSE

The purpose of the study was to identify influential factors contributing to the variation with which antireflux procedures (ARPs) are performed at freestanding children's hospitals in the United States.

METHODS

We conducted an online survey of pediatric surgeons working in Child Health Corporation of America (CHCA) member hospitals in which we examined decision making for ARPs.

RESULTS

Thirty-six percent (n = 121) of contacted surgeons responded. Eighty percent reported requiring preoperative upper gastrointestinal series before ARPs, and 13% require a pH probe study. Although surgeons ranked their own opinion as the most important in preoperative decision making, parents and referring physicians played significant roles in hypothetical scenarios. In children with negative/equivocal objective studies, more than half of surgeons reported offering ARP when the referring specialist felt that ARP was indicated. Despite equivocal studies, 20% of the surgeons reported offering ARP when the parents were convinced that ARP would help. In a patient with both a positive pH probe and upper gastrointestinal series, 46% of surgeons reported declining ARP if parents were hesitant.

CONCLUSIONS

These data suggest that a surgeon's final decision to perform ARP may be just as influenced by nonobjective factors, such as referring physician and parental opinions, as it is by objective studies. Our survey reinforces the need for further examination of specific factors in preoperative decision making for ARPs in the pediatric population.

Development of a quality of life instrument for pediatric gastroesophageal reflux disease: qualitative interviews

OBJECTIVES

Antireflux procedures (ARP) are commonly performed in children and there is no disease-specific quality of life (QOL) instrument for gastroesophageal reflux (GERD) in children. The aim of this study was to identify the relevant domains for developing such an instrument. These domains will be validated in a future study.

PATIENTS AND METHODS

Parents of 19 patients (age 2 months-18 years) clinically diagnosed with GERD were recruited to complete semistructured interviews. Seven patients with adequate verbal skills were also interviewed. Patients were treated medically (13 patients) or with an ARP (6 patients). The interviews were analyzed using grounded theory.

RESULTS

GERD affects QOL through the following domains: symptom severity, feeding quality, sleep quality, hygiene, growth and development, social quality, self-image, coping skills, family QOL, health care usage, and impact of ARP. A greater-than-expected effect on parental QOL and remarkable use of accommodation were identified.

CONCLUSIONS

A pediatric GERD-specific instrument cannot rely on QOL perception alone, but must address broadly the impact of the disease and the effect of coping skills on the child and his or her family in their activities of daily living and interaction with society. We have identified reproducible domains that will serve as the foundation for such an instrument.

Reflux events detected by pH-MII do not determine fundoplication outcome

BACKGROUND

Because of complications and its invasive nature, fundoplication is often a treatment of last resort for children with gastroesophageal reflux. Gastroesophageal reflux testing does not always predict who will benefit from antireflux surgery. Furthermore, there are no studies to determine whether a higher preoperative reflux burden, including acid and nonacid reflux, is associated with an improved postfundoplication outcome. The aim of the study was to determine predictors of fundoplication outcome including acid and nonacid reflux burden.

PATIENTS AND METHODS

We retrospectively reviewed preoperative pH-multichannel intraluminal impedance tracings and medical records of 34 patients who underwent fundoplication. Patients were categorized as improved or not improved, and the demographic and reflux characteristics were compared between groups. Multivariate analysis was performed to determine predictors of outcome.

RESULTS

No single reflux marker, including the number of acid, nonacid, total events, or the percentage of time that reflux was in the esophagus, predicted fundoplication outcome (P > 0.1). Neither a positive symptom index nor a positive symptom sensitivity index predicted postoperative improvement (P > 0.4). Receiver operating characteristic curve analysis failed to reveal an ideal value to maximize sensitivity for either the symptom index or the symptom sensitivity index.

CONCLUSIONS

pH-multichannel intraluminal impedance testing may not be a useful tool in predicting fundoplication outcome.

Reflux related hospital admissions after fundoplication in children with neurological impairment: retrospective cohort study

OBJECTIVE

To examine the impact of fundoplication on reflux related hospital admissions for children with neurological impairment.

DESIGN

Retrospective, observational cohort study. Setting 42 children's hospitals in the United States.

PARTICIPANTS

3721 children with neurological impairment born between 2000 and 2005 who had at least one hospital admission at a study hospital before their fundoplication.

INTERVENTION

Fundoplication.

MAIN OUTCOME MEASURES

Incident rate ratio for reflux related hospital admissions, defined as the post-fundoplication admission rate divided by the pre-fundoplication admission rate.

RESULTS

Of the 955 285 children born during the study period, 144,749 (15%) had neurological impairment. Of these, 27,720 (19%) were diagnosed as having gastro-oesophageal reflux disease, of whom 6716 (24%) had a fundoplication. Of these, 3721 (55%) had at least one previous hospital admission and were included in the study cohort. After fundoplication, hospital admissions decreased for any reflux related cause (incident rate ratio 0.69, 95% confidence interval 0.67 to 0.72; P<0.01), aspiration pneumonia (0.71, 0.62 to 0.81; P<0.01), gastro-oesophageal reflux disease (0.60, 0.57 to 0.63; P<0.01), and mechanical ventilation (0.40, 0.37 to 0.43; P<0.01), after adjustment for other patient and hospital related factors that may influence reflux related hospital admissions. Hospital admissions increased for asthma (incident rate ratio 1.52, 1.38 to 1.67; P<0.01) and remained constant for pneumonia (1.07, 0.98 to 1.17; P=0.16). Conclusions Children with neurological impairment who have fundoplication had reduced short term reflux related hospital admissions for aspiration pneumonia, gastro-oesophageal reflux disease, and mechanical ventilation. However, admissions for pneumonia remained constant and those for asthma increased after fundoplication. Comparative effectiveness data for other treatments (such as gastrojejunal feeding tubes) are unknown.

Pediatric gastroesophageal reflux clinical practice guidelines: joint recommendations of the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition (NASPGHAN) and the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN)

OBJECTIVE

To develop a North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition (NASPGHAN) and European Society for Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) international consensus on the diagnosis and management of gastroesophageal reflux and gastroesophageal reflux disease in the pediatric population.

METHODS

An international panel of 9 pediatric gastroenterologists and 2 epidemiologists were selected by both societies, which developed these guidelines based on the Delphi principle. Statements were based on systematic literature searches using the best-available evidence from PubMed, Cumulative Index to Nursing and Allied Health Literature, and bibliographies. The committee convened in face-to-face meetings 3 times. Consensus was achieved for all recommendations through nominal group technique, a structured, quantitative method. Articles were evaluated using the Oxford Centre for Evidence-based Medicine Levels of Evidence. Using the Oxford Grades of Recommendation, the quality of evidence of each of the recommendations made by the committee was determined and is summarized in appendices.

RESULTS

More than 600 articles were reviewed for this work. The document provides evidence-based guidelines for the diagnosis and management of gastroesophageal reflux and gastroesophageal reflux disease in the pediatric population.

CONCLUSIONS

This document is intended to be used in daily practice for the development of future clinical practice guidelines and as a basis for clinical trials.

Successful and safe delivery of anesthesia and perioperative care for children with complex special health care needs

STUDY OBJECTIVE

To determine the utilization of anesthesia resources by children with complex special health care needs.

DESIGN

Observational, inception cohort study of medical records.

SETTING

Urban, pediatric, tertiary-care hospital.

MEASUREMENTS

All general anesthetic cases were screened for preexisting complex special health care needs. Medical records were reviewed for demographic, clinical, and outcome data.

MAIN RESULTS

435 children with complex special health care needs accounted for 479 delivered general anesthetic cases. This figure represented 14% of the total 3,437 cases presenting during the study period. It also represented 22% (49 of 224) of all cancellations. Down syndrome was the most identifiable developmental disorder (n = 43, 9%). Another 143 (30%) cases showed preexisting technology dependence. Scheduled surgical procedures (n = 425, 89%) comprised the majority of cases. Intraoperative and recovery room complications occurred in 6 (1%) and 133 (28%) cases, respectively. Eleven (2.3%) cases required unplanned post-anesthetic hospital ward or pediatric intensive care unit admission. Documentation of health care proxy or resuscitation status was not identified in any child under 18 years, and in only 4 of 33 children older than 18 years.

CONCLUSIONS

Children with complex special health care needs represented one out of 7 of all pediatric general anesthetic cases at a tertiary-care, academic center.

Impact of fundoplication versus gastrojejunal feeding tubes on mortality and in preventing aspiration pneumonia in young children with neurologic impairment who have gastroesophageal reflux disease

OBJECTIVE

Aspiration pneumonia is the most common cause of death in children with neurologic impairment who have gastroesophageal reflux disease. Fundoplications and gastrojejunal feeding tubes are frequently employed to prevent aspiration pneumonia in this population. Which of these approaches is more effective in preventing aspiration pneumonia and/or improving survival is unknown. The objective of this study was to compare outcomes for children with neurologic impairment and gastroesophageal reflux disease after either a first fundoplication or a first gastrojejunal feeding tube.

PATIENTS AND METHODS

This was a retrospective, observational cohort study of children with neurologic impairment who had either a fundoplication or gastrojejunal feeding tube between January 1997 and December 2005 at a tertiary care children's hospital. Main outcome measures were postprocedure aspiration pneumonia-free survival and mortality. Propensity analyses were used to control for bias in treatment assignment and prognostic imbalances.

RESULTS

Of the 366 children with neurologic impairment and gastroesophageal reflux disease, 43 had a first gastrojejunal feeding tube and 323 underwent a first fundoplication. Median length of follow-up was 3.4 years. Children who received a first fundoplication had similar rates of aspiration pneumonia and mortality after the procedure compared with those who had a first gastrojejunal feeding tube, when adjusting for the treatment assignment using propensity scores.

CONCLUSIONS

Aspiration pneumonia and mortality are not uncommon events after either a first fundoplication or a first gastrojejunal feeding tube for the management of gastroesophageal reflux disease in children with neurologic impairment. Neither treatment option is clearly superior in preventing the subsequent aspiration pneumonia or improving overall survival for these children. This complex clinical scenario needs to be studied in a prospective, multicenter, randomized control trial to evaluate definitively whether 1 of these 2 management options is more beneficial.

Enteral feeding in neurologically impaired children with gastroesophageal reflux: Nissen fundoplication and gastrostomy tube placement versus percutaneous gastrojejunostomy

Parents or caregivers of neurologically impaired children with gastroesophageal reflux who require enteral nutrition are often faced with the option of having their child undergo an antireflux surgery and placement of a gastrostomy tube or have a percutaneous gastrojejunostomy tube placed under fluoroscopic guidance. It is important that nurses have an understanding of these procedures and their associated risks and benefits as well as knowledge of the impact each might have on the daily life and care of these children to help support families during this decision-making process.

Hospital admissions for respiratory symptoms and failure to thrive before and after Nissen fundoplication

PURPOSE

The purpose of this study is to determine whether Nissen fundoplication decreases hospital admissions for respiratory symptoms and failure to thrive (FTT).

METHODS

A retrospective study using discharge abstract data from Southern California Kaiser Permanente hospitals during the last decade was done. Three hundred forty-two pediatric patients had at least one Nissen fundoplication. Hospital admissions for aspiration and other pneumonia, respiratory distress/apnea, and FTT were determined before and after Nissen fundoplication. Age and associated neurologic disorders were also studied. Statistical analysis was determined by chi(2) analysis, Poisson regression analysis, and relative risk.

RESULTS

The number of patients requiring hospital admission for aspiration and other pneumonia, respiratory distress/apnea, and FTT was similar before and after Nissen fundoplication. The proportion of readmission within 1 year after Nissen fundoplication for aspiration pneumonia was 0.1250 (95% confidence interval [CI], 0.0266-0.3236); other pneumonia, 0.5465 (95% CI, 0.4355-0.6542); respiratory distress/apnea, 0.5039 (95% CI, 0.4145-0.5931); and FTT, 0.5669 (95% CI, 0.4761-0.6545). Associated neurologic disorders independently increased hospital admissions for aspiration and other pneumonia, respiratory distress/apnea, and FTT. Age was inversely related to hospital admissions for respiratory distress and FTT.

CONCLUSION

Nissen fundoplication did not improve hospital admissions for pneumonia, respiratory distress/apnea, and FTT. Associated neurologic disorders increased readmissions for pneumonia, respiratory distress/apnea, and FTT, whereas increasing age decreased readmission for respiratory distress and FTT.

Gastrointestinal tract feeding access and the role of fundoplication in combination with gastrostomy

PURPOSE OF REVIEW

Feeding access and associated antireflux procedures continue to be some of the most common operations performed in pediatric patients. This review will discuss the various feeding access procedures available, including minimally invasive techniques, and further elaborate on appropriate indications for a concurrent antireflux procedure as well as alternatives to fundoplication.

RECENT FINDINGS

Gastrostomy and jejunostomy can be successfully placed using endoscopic or laparoscopic techniques with low complication rates. Nissen fundoplication is well described laparoscopically but failure with recurrent gastroesophageal reflux has resulted in the development of other operative alternatives.

SUMMARY

Decisions concerning appropriate long-term feeding access must be individualized, understanding the advantages and disadvantages of gastrostomy and jejunostomy techniques. Laparoscopic Nissen fundoplication is successful for treatment of patients who fail medical therapy of gastroesophageal reflux, but recurrent gastroesophageal reflux is a persistent problem that requires innovative solutions.
