National trends in the use of antireflux procedures for children

Prophylactic antireflux procedures are not necessary in neurologically impaired children undergoing gastrostomy placement

PURPOSE

Fundoplication is frequently used in children with neurologic impairment even in the absence of reflux due to concerns for future gastric feeding intolerance, but supporting data are lacking. We aimed to determine the incidence of secondary antireflux procedures (fundoplication or gastrojejunostomy (GJ)) post gastrostomy tube (GT) placement in children with and without neurologic impairment.

METHODS

Children under 18 undergoing a GT placement without fundoplication between 2010 and 2020 were identified utilizing the PearlDiver Mariner national patient claims database. Children with a diagnosis of cerebral palsy or a degenerative neurologic disease were identified and compared to children without these diagnoses. The incidence of delayed fundoplication or conversion to GJ were compared utilizing Kaplan-Meier and Cox proportional hazards regression analyses.

RESULTS

A total of 14,965 children underwent GT placement, of which 3712 (24.8%) had a diagnosis of neurologic impairment. The rate of concomitant fundoplication was significantly higher among children with a diagnosis of neurologic impairment as compared to those without (9.3% vs 6.4%, p < 0.001). While children with neurologic impairment had a significantly higher rate of fundoplication or GJ conversion at 5 years compared to children without (12.6% [95% confidence interval (CI): 11.4%-13.8%] vs 8.6% [95% CI 8.0%-9.2%], p < 0.001), the overall incidence remained low.

CONCLUSION

Although children with neurologic impairment have a higher rate of requiring an antireflux procedure or GJ conversion than other children, the overall rate remains less than 15%. Fundoplication should not be utilized in children without clinical reflux on the basis of neurologic impairment alone.

Fundoplication without esophagocrural sutures: Long-term follow-up of a randomized clinical trial

INTRODUCTION

We previously conducted a randomized trial that showed a lack of need for esophagocrural (EC) sutures during fundoplication when no esophageal dissection was performed. There was no difference in wrap herniation or other complications in the group without EC sutures at a median 1.5 years of follow-up. In this follow-up study, we aim to evaluate long-term symptom control and complication profiles in these patients.

METHODS

106 patients were randomized and participated in the original trial. We were primarily concerned with identification of late complications and persistence of symptoms. Presently, we conducted a retrospective chart review and a telephone follow-up survey at a minimum of 6.5 years after fundoplication.

RESULTS

100 patients were alive at late follow-up and 70% of caregivers responded to the telephone survey. 53% of patients were male; 76% were Caucasian. Of these children, 39 (56%) received four EC sutures, while 31 (44%) did not. Follow-up was conducted at a median of 8.7 years [IQR 8.2,9.7] post-fundoplication. Late wrap herniation was not demonstrated radiographically on chart review or caregiver report in either group. The rate of residual reflux symptoms, post-operative hospitalizations for pneumonia, failure to thrive (FTT), and brief resolved unexplained event (BRUE) were also similar between groups.

CONCLUSION

Long-term follow-up in children who underwent fundoplication without esophagocrural sutures demonstrates no difference in symptom management or subsequent hospitalizations at a minimum of 6.5-year follow-up.

Trends in fundoplication volume for pediatric gastroesophageal reflux disease

INTRODUCTION

Fundoplication for gastro-esophageal reflux disease (GERD) has been commonly performed by pediatric surgeons, however there are no recent data documenting fundoplication trends. Changes in fundoplication volume impact pediatric surgical training and may reflect changes in care for children with severe GERD.

MATERIALS & METHODS

The Pediatric Health Information System (PHIS) was queried from 2010-2019 for children with ICD-9/ICD-10 codes for GERD, fundoplication, and gastrostomy. Institutional surgical volume and patient demographics were examined over time. A secondary analysis using the Accreditation Council for Graduate Medical Education case logs for pediatric surgery fellows was performed across the same years to assess effects upon surgical volume for trainees.

RESULTS

Mean institutional fundoplication case volume decreased from 50 in 2010 to 17 in 2019. Trends were similar between institutions with and without fellowship programs when corrected by total operative volume. Patient characteristics were relatively unchanged between 2010 and 2019. Fundoplication volume reported in fellow case logs decreased from 46 in 2010 to 26 in 2019, mirroring national data.

CONCLUSIONS

Institutional volume for fundoplication in children with GERD has seen a 3-fold decrease over the last decade, mirrored by an almost 2-fold decrease in case volume reported by pediatric surgery fellows.

Current issues of gastro-oesophageal reflux disease surgical treatment in children

Gastro-oesophageal reflux (GER) disease is one of the most common diseases amongst a wide range of chronic inflammatory diseases of the gastrointestinal tract in children of all ages, significantly impairing the quality of life of the child and posing a serious threat to the health of the patient. From 2008 to 2019, 134 patients aging from 6 months to 12 years were hospitalised at the Scientific Center for Pediatrics and Pediatric Surgery including 69 (51%) infants. Of them, 51 (38%) were the patients with persistent manifestations of regurgitation, despite an outpatient course of conservative therapy; 29 (22%) patients with recurrent reflux-associated pneumonia; also, 35 (26%) children with GER in the structure of the main pathology of the central nervous system, as well as 19 (14%) patients after surgery of the anastomosis of the oesophagus with its atresia. One hundred and seven (79.8%) patients underwent surgery. Nissen oesophagofundoplication was traditionally performed in 41 (38%) patients, in combination with Stamm gastrostomy in 14 (34%), with Mikulich pyloroplasty in 9 (22%) and in combination with gastrostomy and pyloroplasty in 12 (29%) children. Laparoscopic Nissen oesophagofundoplication was used in 16 (15%) cases. Thall oesophagofundoplication was performed in 48 (45%) patients, while in two (2%) cases, Boerema gastropexy was conducted. The immediate results were studied in all 107 patients. Complications in the form of gastric distress syndrome were revealed in four (3.7%) patients who did not undergo pyloroplasty, which in two (1.9%) cases required additional surgery of the stomach draining, whereas in the other two (1.9%) patients, the distress syndrome was stopped conservatively. A dumping syndrome was identified in two (1.9%) patients. Timely recognition of the pathological process, its nature and prevalence determines the indications for the use of various methods of operation, which are based on an individual approach to each patient.

Aspiration pneumonia after antireflux surgery among neurologically impaired children with GERD

BACKGROUND AND OBJECTIVE

Aspiration pneumonia is a common and serious complication to gastroesophageal reflux disease (GERD) among neurologically impaired children. Medication of GERD does not effectively prevent aspiration pneumonia, and whether antireflux surgery with fundoplication is better in this respect is uncertain. The objective was to determine whether fundoplication prevents aspiration pneumonia among children with neurological impairment and GERD.

METHODS

This was a population-based cohort study from Denmark, Finland, Norway and Sweden, consisting of neurologically impaired children with GERD who underwent fundoplication. The risk of aspiration pneumonia before fundoplication (preoperative person-time) was compared with the risk after surgery (postoperative person-time). Multivariable Cox regression provided hazard ratios (HRs) with 95% confidence intervals (CIs). Except for confounding adjusted for by means of the "crossover like" design, the HRs were adjusted for age, sex, year of entry and respiratory diseases.

RESULTS

Among 578 patients (median age 3.5 years), the preoperative person-time was 956 years and the postoperative person-time was 3324 years. Fundoplication was associated with 56% decreased overall HR of aspiration pneumonia (HR 0.44, 95% CI 0.27-0.72), and the HRs decreased over time after surgery. The risk of other types of pneumonia than aspiration pneumonia was not clearly decreased after fundoplication (HR 0.79, 95% CI 0.59-1.08). The 30-day mortality rate was 0.7% and the complication rate was 3.6%.

CONCLUSIONS

Antireflux surgery decreases, but does not eliminate, the risk of aspiration pneumonia among neurologically impaired children with GERD. Fundoplication may be a treatment option when aspiration pneumonia is a recurrent problem in these children.

A Team-Based Approach for Children With Congenital Cardiac Disease Undergoing Antireflux Procedure With Gastrostomy

INTRODUCTION

Laparoscopic Nissen fundoplication with gastrostomy tube (LPNF-GT) placement is often indicated in children with congenital cardiac diseases (CCDs) for nutritional optimization. This study aims to evaluate institutional outcomes of LPNF-GT, with a team-based approach in operative management.

METHODS

Five years of an institutional database at a tertiary care children's hospital was queried for LPNF-GT in children with CCDs. Descriptive analyses were performed. A national comparison was performed utilizing the 2012-2013 Pediatrics NSQIP database, using propensity score matching. Outcome measures of interest were operative-time, unplanned readmission, and 30-day mortality.

RESULTS

A team-based approach was utilized in 51 cases. Median operative time was 68.5 (IQR: 48-89) minutes. All patients tolerated tube feeds postoperatively. All patients survived 30 days post surgery. When compared to 136 similarly matched children nationally, the risk-adjusted operative time with a team-based approach was 47.38 (12.43-82.33) minutes shorter (P < .05). There were no statistically significant differences in the likelihood of being in the hospital past 30 days, unplanned readmissions, and mortality (P > .05).

CONCLUSION

LPNF-GT can be safely performed in children with CCDs. A team-based approach demonstrates improved operative time and achieved similar outcomes when compared nationally.

Boix-Ochoa (Partial Fundoplication) Treats Reflux, Even in Neurologically Impaired Patients. Can it Take the Title of "Gold Standard" from Total Fundoplication?

BACKGROUND

In 4-5% of cases of gastroesophageal reflux disease (GERD), surgical treatment is required. The aim of the study was to evaluate the success of Boix-Ochoa antireflux surgery, which is considered more physiologic with a higher failure rate (need for reoperation) than Nissen fundoplication, which is believed to be the gold standard operation.

METHOD

In the 13 years from 2005 to 2018, the medical records of all children who underwent Boix-Ochoa in a single institution by pediatric surgeons were reviewed retrospectively.

RESULTS

A total of 133 fundoplications were performed, of which patients were divided into four groups: neurologically impaired, structurally impaired, neurologically and structurally impaired, and neurologically and structurally normal; there were 64, 8, 34, and 27 patients in each group, respectively. Structural impairments included hiatal hernia and esophagus atresia, having previously had a gastrostomy and esophageal stenosis. The most common short-term complication was distal esophageal stenosis (13%), which caused vomiting and dysphagia, and was treated by dilatations. There were six (4.5%) recurrences of GER, one in the neurologically and structurally impaired group with a hiatal hernia and five in the structurally impaired group (three esophagus atresias, two caustic esophageal strictures). The mean follow-up period was 5.27 ± 3.43 years. Neurological impairment did not affect the success rate.

CONCLUSION

Although there has not any literature demonstrating significant benefits of one procedure, we detected with this largest study in the pediatric literature about Boix-Ochoa fundoplication (more physiologic and easily performed) that it was successful (95%) in protecting reflux even in neurologically impaired patients (98%). We consider Boix-Ochoa (partial fundoplication) to be an alternative method to Nissen (complete fundoplication), and it can be done safely with a high success rate.

It Is a Wrap! Or Is It?: The Role of Fundoplication in Infant Feeding Intolerance

Purpose: Fundoplication is one of the most common procedures performed by pediatric surgeons, frequently for gastroesophageal reflux with feeding intolerance. No consensus exists in its management, with multiple institutions opting for medical therapy over surgical intervention. Methods: A case-based survey was administered at a national pediatric surgery conference. Clinical vignettes described former-premature infants with reflux and feeding intolerance with or without failure to thrive (FTT), neurological impairment, complex cardiopathy, and respiratory symptoms. Odds ratios (ORs) for fundoplication were calculated from participants' responses. Results: Surgeons elected to perform fundoplication in 14%-74% of cases. The OR for performing fundoplication in the presence of FTT was 1.84 (confidence interval [CI] 1.34-2.54, P = .0002) overall, achieving significance in subgroup analysis for cardiopathy (OR 3.56, CI 1.88-6.71, P = .0001) and neurological impairment (OR 1.79, CI 1.04-3.07, P = .04), but not in the absence of these comorbidities (OR 1.05, CI 0.61-1.83, P = .86). The OR for fundoplication in the presence of neurological impairment was 1.97 (CI 1.34-2.90, P = .0005) and that for cardiopathy was 1.70 (CI 1.20-2.40, P = .003), independent of FTT status. In subgroup analysis, the greatest predictors for fundoplication were neurological impairment with FTT (OR 2.63, CI 1.55-4.48, P = .0004) and complex cardiopathy with FTT and cough/syncope (OR 7.14, CI 4.05-12.58, P < .0001). Presence of cardiopathy without FTT had the overall lowest odds of fundoplication (OR 0.40, CI 0.21-0.78, P = .006). Conclusion: Surgeons tend to perform fundoplication in the presence of FTT and other comorbidities, particularly when these are concurrent. Respiratory symptoms are a strong predictor for fundoplication in patients with complex cardiopathies.

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.

Surgical management of gastroesophageal reflux disease (GERD) in children: A systematic review

OBJECTIVE

The goal of this systematic review by the American Pediatric Surgical Association Outcomes and Evidence-Based Practice Committee was to derive recommendations from the medical literature regarding the surgical treatment of pediatric gastroesophageal reflux disease (GERD).

METHODS

Five questions were addressed by searching the MEDLINE, Cochrane, Embase, Central, and National Guideline Clearinghouse databases using relevant search terms. Consensus recommendations were derived for each question based on the best available evidence.

RESULTS

There was insufficient evidence to formulate recommendations for all questions. Fundoplication does not affect the rate of hospitalization for aspiration pneumonia, apnea, or reflux-related symptoms. Fundoplication is effective in reducing all parameters of esophageal acid exposure without altering esophageal motility. Laparoscopic fundoplication may be comparable to open fundoplication with regard to short-term clinical outcomes. Partial fundoplication and complete fundoplication are comparable in effectiveness for subjective control of GERD. Fundoplication may benefit GERD patients with asthma, but may not improve outcomes in patients with neurologic impairment or esophageal atresia. Overall GERD recurrence rates are likely below 20%.

CONCLUSIONS

High-quality evidence is lacking regarding the surgical management of GERD in the pediatric population. Definitive conclusions regarding the effectiveness of fundoplication are limited by patient heterogeneity and lack of a standardized outcomes reporting framework.

TYPE OF STUDY

Systematic review of level 1-4 studies.

LEVEL OF EVIDENCE

Increased morbidity and mortality in cardiac patients undergoing fundoplication

BACKGROUND

Infants with congenital cardiac disease (CCD) often require gastrostomy tube placement (GT) and need antireflux procedures, such as fundoplications. Our purpose was to compare morbidity/mortality rates among infants with CCD undergoing GT, fundoplication, or both.

METHODS

Using the NSQIP-Pediatric, we identified 4070 patients <1-year-old who underwent GT and/or fundoplication from 2012 to 2014. 2346 infants (58%) had CCD categorized as minor, major or severe. Regression models were used to estimate the association of CCD with morbidity/mortality.

RESULTS

Among all patients undergoing fundoplication, there were increased odds of morbidity/mortality among CCD patients compared to non-CCD patients (OR 2.15; p < 0.001). Odds of complications decreased when procedures were performed laparoscopically or later in the first year of life. Using GT alone as a reference, fundoplication alone (OR 1.67; p < 0.001) and GT with fundoplication (OR 1.82; p < 0.001) had increased odds of morbidity/mortality among cardiac patients. Increased risk persisted after stratification by severity of CCD and after accounting for surgical approach.

CONCLUSION

Fundoplication is associated with increased odds of morbidity/mortality in infants with CCD compared to GT alone. Risks are lower with laparoscopic approach and if surgery is delayed until later in the first year of life. Timing and surgical approach for patients with CCD requires further investigation.

Exploring regional variability in utilization of antireflux surgery in children

BACKGROUND

There is significant variation surrounding the indications, surgical approaches, and outcomes for children undergoing antireflux procedures (ARPs) resulting in geographic variation of care. Our purpose was to quantify this geographic variation in the utilization of ARPs in children.

METHODS

A cross-sectional analysis of the 2009 Kid's Inpatient Database was performed to identify patients with gastroesophageal reflux disease or associated diagnoses. Regional surgical utilization rates were determined, and a mixed effects model was used to identify factors associated with the use of ARPs.

RESULTS

Of the 148,959 patients with a diagnosis of interest, 4848 (3.3%) underwent an ARP with 2376 (49%) undergoing a laparoscopic procedure. The Northeast (2.0%) and Midwest (2.2%) had the lowest overall utilization of surgery, compared with the South (3.3%) and West (3.4%). After adjustment for age, case-mix, and surgical approach, variation persisted with the West and the South demonstrating almost two times the odds of undergoing an ARP compared with the Northeast. Surgical utilization rates are independent of state-level volume with some of the highest case volume states having surgical utilization rates below the national rate. In the West, the use of laparoscopy correlated with overall utilization of surgery, whereas surgical approach was not correlated with ARP use in the South.

CONCLUSIONS

Significant regional variation in ARP utilization exists that cannot be explained entirely by differences in patient age, race/ethnicity, case-mix, and surgical approach. In order to decrease variation in care, further research is warranted to establish consensus guidelines regarding indications for the use ARPs for children.

Fundoplication with gastrostomy vs gastrostomy alone: a systematic review and meta-analysis of outcomes and complications

PURPOSE

We compare the outcomes of fundoplication with gastrostomy vs gastrostomy alone and review the need for subsequent fundoplication after the initial gastrostomy alone.

METHODS

We searched studies published from 1969 to 2016 for comparative outcomes of concomitant fundoplication with gastrostomy (FGT) vs gastrostomy insertion alone (GT) in children. Gastrostomy methods included open, laparoscopic, and endoscopic procedures. Primary aims were minor and major complications. Secondary aims included post-operative reflux-related complications, fundoplication specific complications, and need for subsequent fundoplication after GT.

RESULTS

We reviewed 447 studies; 6 observational studies were included for meta-analysis, encompassing 2730 children undergoing GT (n = 1745) or FGT (n = 985). FGT was associated with more minor complications [19.9 vs 11.4%, OR 2.02, 95% confidence interval (CI) 1.43-2.87, p ≤ 0.0001, I ² = 0%], minor complications requiring revision (6.8 vs 3.0%, OR 2.27, 95% CI 1.28-4.05, p = 0.005, I ² = 0%), and more overall complications (21.3 vs 12.0%, OR 1.99, 95% CI 1.43-2.78, p < 0.0001, I ² = 0%). Incidence of major complications (1.8 vs 2.0%, OR 1.39, 95% CI 0.62-3.11, p = 0.42, I ² = 5%) and reflux-related complications (8.8 vs 10.3%, OR 0.75, 95% CI 0.35-1.68, p = 0.46, I ² = 0%) in both groups was similar. Incidence of subsequent fundoplication in GT patients was 8.6% (mean).

CONCLUSIONS

Gastrostomy alone is associated with fewer minor and overall complications. Concomitant fundoplication does not significantly reduce reflux-related complications. As few patients require fundoplication after gastrostomy, current evidence does not support concomitant fundoplication.

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.

Nissen fundoplication in children with and without neurological impairment: A prospective cohort study

BACKGROUND

It is assumed that children with neurological impairment (NI) have inferior results after fundoplication compared to those without NI (non-NI). The aim of this study was to assess outcome after fundoplication in children with and without NI.

METHODS

87/105 patients (46 NI, 41 non-NI) undergoing fundoplication between 2003 and 2009 were included in this prospective two-center cohort study. Complications occurring within the first 30days were scored from 0 to 100 by the comprehensive complication index (CCI). Follow-up included clinical examination, upper gastrointestinal contrast study and 24-h pH monitoring 6months postoperatively, then phone-interviews 1, 2 and 4years later.

RESULTS

There were no statistical differences in age (NI 3.1 years [0.2-15.2] vs non-NI 5.0 years [0.4-15], p=.14) or in total CCI score (NI 20.9 [0-44.9] vs non-NI 8.7 [0-40.6], p=.57). Hospital stay was longer for NI children (9days [4-57] vs non-NI: 4days [2-16], p<0.001). More than 90% of parents in both groups reported that the fundoplication had improved the child's overall condition. Recurrence of gastroesophageal reflux disease (GERD) was diagnosed in 12 NI and 7 non-NI patients (p=.31).

CONCLUSIONS

Early complications, GERD recurrence, and long-term parental satisfaction after fundoplication did not differ between NI and non-NI patients.

Concomitant fundoplication increases morbidity of gastrostomy tube placement

BACKGROUND

Fundoplication is often performed in conjunction with gastrostomy tube (GT) placement in children, but there is a great deal of variation in rates of and indications for this procedure. Little is known about the impact of fundoplication on peri-operative outcomes. This study examines a national cohort of pediatric patients to compare risk-adjusted surgical outcomes in patients undergoing GT placement with or without concomitant fundoplication.

METHODS

We identified all patients undergoing GT placement in the 2012 National Surgical Quality Improvement Program - Pediatric. We evaluated demographics, comorbidities, complications, and length of stay for GT with fundoplication versus GT alone. We defined composite morbidity as a dichotomous variable for the presence of any complication. Logistic regression was performed to identify predictors of morbidity after adjusting for covariates.

RESULTS

1289 GT patients were identified, and 148 (11.5%) underwent concurrent fundoplication. The fundoplication patients were more likely to be younger, have cardiac risk factors, and be on respiratory support. They also had higher rates of surgical site infection (7.4% vs 3.7%, p=0.03) and composite morbidity (16.9% vs 8.7%, p=0.001), and longer LOS (median 5 vs 3 days, p=<0.0001) compared to GT only. After adjusting for covariates, fundoplication was a predictor of composite morbidity and increased LOS.

CONCLUSION

Concomitant fundoplication is an independent risk factor for 30-day post-operative morbidity in patients undergoing GT placement. These findings do not negate the value of fundoplication but underscore the importance of careful patient selection, and should be taken into consideration when discussing risks and benefits with families.

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.

Prevalence of Chronic Metoclopramide Use and Associated Diagnoses in the US Pediatric Population

OBJECTIVE

Metoclopramide is the only medication widely used to promote gastrointestinal motility in the USA. Despite its appreciable risk of central nervous system complications, it continues to be prescribed to children for chronic use. We sought to estimate the prevalence of chronic metoclopramide use among US children and identify the diagnoses that may have prompted this use. The US metoclopramide label lists only two indications in adults: symptomatic gastroesophageal reflux (GERD) and diabetic gastroparesis. The latter is rare in children so, in examining the indications likely to have prompted chronic metoclopramide use, we focused on GERD.

METHODS

From two health services databases representing privately and publically insured children, respectively, we estimated the number of US children who used metoclopramide chronically and identified the diagnoses recorded at approximately the time when the chronic use began. We defined chronic use liberally as ≥ 35 days' supply, or conservatively as ≥ 130 days' supply in a 6-month period. For each chronic-use definition, insurance type, and age group, we estimated the proportion of children using metoclopramide chronically. We applied these proportions to US population estimates.

RESULTS

Under the liberal and conservative definitions, respectively, 89,020 and 28,222 US children used metoclopramide chronically.

CONCLUSION

In spite of its risk, substantial numbers of US children use metoclopramide chronically for symptoms suggestive of GERD.

National trends and outcomes of pediatric gastrostomy tube placement

OBJECTIVES

National outcomes data regarding surgical gastrostomy tube (G-tube) and percutaneous endoscopic gastrostomy (PEG) tube procedures are lacking. Our objectives were to describe trends in G-tube and PEG procedures, examine regional variation, and compare outcomes.

METHODS

This was a retrospective study using pediatric admissions during 1997, 2000, 2003, 2006, and 2009 from the Kids' Inpatient Database. Length of stay and cost were adjusted for demographics, complexity, setting, year, and infection or surgical complication.

RESULTS

G-tubes were placed during 64,412 admissions, increasing from 16.6 procedures/100,000 US children in 1997 to 18.5 in 2009. Surgical gastrostomy rates increased by 19% (0.17 procedures/100,000/year, P < 0.002) and, among children <1 year, they increased by 32% (2.56 procedures/100,000/year, P < 0.01). PEG rates did not increase (0.02 procedures/100,000/year, P = 0.47) in the study years. The West had an 18% higher rate than the national average for surgical G-tubes and a 10% higher rate for PEGs. When the sole procedure during the admission was gastrostomy, the G-tube was associated with a 19% (confidence interval 9.7-57.5) longer length of stay, and a 25% higher cost (confidence interval 16.4-34.5) compared with PEG.

CONCLUSIONS

Surgical gastrostomy insertion rates have increased whereas PEG rates have not, despite evidence of better severity-adjusted outcome measures for PEG tubes. Surgical gastrostomy insertion in children <1 year of age yielded the greatest increase, which may relate to a changing patient population; however, regional variation suggests that provider preference also plays a role. Our data underline the need for more robust collection and analysis of surgical outcomes to guide decision making.

Dextranomer hyaluronic acid copolymer effects on gastroesophageal junction

OBJECTIVE

The outcomes of fundoplication for gastroesophageal reflux disease are suboptimal in many children, and alternatives are clearly needed. Dextranomer hyaluronic acid (DxHA) copolymer, an agent with proven efficacy in vesicoureteral reflux, was studied with respect to its effects on the gastroesophageal junction (GEJ).

METHODS

Twelve New Zealand white rabbits underwent measurement of lower esophageal sphincter pressure followed by laparotomy and injection into the muscular layer of the GEJ (controls, 1.0 mL saline; low-dose DxHA [0.5 mL]; high-dose DxHA [1.0 mL]). After a 12-week survival period, the animals underwent manometry, sacrifice, and necropsy. Organs were examined histologically by pathologists blinded to the injection delivered.

RESULTS

All animals survived. Weight gain was equal in the 3 groups. There was no significant difference in mean lower esophageal sphincter pressure from baseline in any group (control 2.3 mmHg [95% confidence interval, CI -3.3 to 7.9]; low-dose group 3.2 mmHg [95% CI -0.8 to 7.2]; high-dose group -4.0 mmHg [95% CI -18.95 to 10.95]). Histologically, DxHA injection produced an intramural implant, with a foreign body giant cell reaction, and fibroblastic infiltration with collagen deposition. High-dose injection did not consistently result in a qualitative increase in the magnitude of the reaction. There was no mucosal injury or luminal stenosis.

CONCLUSIONS

In this first study evaluating the effects of DxHA injection at the GEJ, a histologic bulking effect was observed without obvious functional complications. The agent may have a role in the treatment of gastroesophageal reflux disease.

Referring physicians' decision making for pediatric anti-reflux procedures

BACKGROUND

Rates of anti-reflux procedures (ARP) vary greatly among pediatric hospitals. How pediatric subspecialists make referral decisions for ARPs has not been described. The aim of this study was to characterize pediatric subspecialists' decision making for referring children for ARPs.

METHODS

Pediatric subspecialists at a single children's hospital were interviewed about their decision making when referring for ARPs. Qualitative analysis was performed on clinicians' perceptions of the risks and benefits of the treatment options. Clinical algorithms were derived from each interview and were compared using the Clinical Algorithm Nosology. Clinical Algorithm Structural Analysis (CASA) scores were calculated to assess algorithm complexity. Clinical Algorithm Patient Abstraction (CAPA) scores on a scale from 0 (different) to 10 (identical) were generated based on algorithm agreement.

RESULTS

The interviews yielded 15 algorithms. There was substantial variation in the providers' perceived risks and benefits of the treatment options. CASA scores ranged from 8 to 28 and CAPA scores ranged from 0 to 5.7 (median, 0), indicating great variation in both complexity and patient management. Management variation included testing (33% of algorithms incorporated pH probe test, 67% upper gastrointestinal, and 47% small bowel follow-through), procedure contraindications (33% considered history of gagging a contraindication to ARP), and use of gastrojejunostomy tubes (20% using gastrojejunostomy tube before ARP).

CONCLUSION

No standards exist for the decision to refer children with gastroesophageal reflux disease for ARP. There is great variation among pediatric subspecialists in their decision making. Differences in providers' perception of the risks and benefits of these procedures contribute to this variation.

Persistent gastrocutaneous fistula: factors affecting the need for closure

PURPOSE

The occurrence of gastrocutaneous fistula (GCF) is a well-known complication after gastrostomy tube placement. We explore multiple factors to ascertain their impact on the rate of persistent GCF formation.

METHODS

We retrospectively reviewed patient records for all gastrostomies (GT) constructed at our institution from 2007 to 2011. Association of GCF with method of placement, concomitant fundoplication, neurologic findings, duration of therapy, and demographics was evaluated using logistic regression.

RESULTS

Nine hundred fifty patients had GTs placed, of which 148 patients had GTs removed and 47 (32%) of 148 required surgical closure secondary to persistent GCF. Laparoscopic and open procedures comprised 79 (53%) of 148 and 69 (47%) of 148, respectively. Seventeen (22%) patients in the laparoscopic group developed persistent GCF, compared to 30 (43%) in the open group (P=0.035, OR=2.52). Seventy-one patients had concomitant Nissen fundoplication. Thirty-one (44%) developed GCF, compared to 16 (21%) without a Nissen (P=0.002, OR=4.94). Patients with button in place for 303 days had persistent GCF incidence of 23%, compared to 45% at 540 days (P<0.001, OR=3.51) and 50% at 850 days (P=0.011, OR=4.51). Patients with device placed at 1.8 months of age were more likely to develop GCF compared to those with device placed at 8.9 months of age (P=0.017, OR=2.35).

CONCLUSION

Open operations, concurrent Nissen and younger age at placement were all statistically significant factors causing persistent GCF.

Morbidity and mortality in total esophagogastric dissociation: a systematic review

BACKGROUND/PURPOSE

Total esophagogastric dissociation has been described as both a primary and a rescue procedure for patients with severe gastroesophageal reflux. Although most commonly used in the neurologically impaired, it has also been used in those with no neurological impairment. The main objective of this study was to determine morbidity and mortality for this procedure.

METHODS

All published cases of esophagogastric dissociation in children were identified. Series were updated where possible by personal communication with the author. Patient characteristics, indications, morbidity, and mortality were analyzed.

RESULTS

One hundred eighty-one cases were identified. One hundred seventeen were primary operations and 64 were rescue procedures. There were 29 (16.0%) early complications and 28 (15.5%) late complications with 6 (3.3%) deaths related to the procedure of a total of 35 deaths. Twenty-one patients (11.6%) required re-operation in the study periods.

CONCLUSIONS

Esophagogastric dissociation has an acceptable morbidity and mortality. It is useful as both a primary and a rescue procedure.

Antireflux surgery in children with neurological impairment: caregiver perceptions and complications

OBJECTIVES

The aim of the present study was to report caregiver perceptions to antireflux surgery and gastrostomy in children with severe neurological impairment and to report the complications of the surgery.

METHODS

Children were identified from a clinic database and clinical information and surgical complications were extracted from the database and hospital medical records. A cross-sectional questionnaire addressing severity of symptoms was administered to parents/caregivers and scored with a 5-point Likert scale (1 is much better to 5, much worse).

RESULTS

A total of 122 children, median age 74 months (interquartile range 29-124), 63% spastic quadriplegic cerebral palsy, had antireflux surgery. Laparoscopic surgery was performed in 77 of 122 (63%) and 117 of 122 (96%) had gastrostomy insertion. Questionnaire was completed by 89 of 122 (73%) children; median duration of time from fundoplication to questionnaire was 77 months (43-89). The majority of caregivers indicated that surgery improved or greatly improved weight gain, chest infections, vomiting, and feeding tolerance. Only 2 caregivers reported that they regretted consenting to surgery. Serious surgical complications occurred in 10%.

CONCLUSIONS

Serious complications were uncommon in this series of antireflux surgery in neurologically impaired children. Although gagging and retching were common following surgery, a high percentage of caregivers reported improved nutrition, reflux-related symptoms, and high levels of satisfaction.

Fundoplication and the pediatric surgeon: implications for shared decision-making and the medical home

OBJECTIVE

Almost one-half of all pediatric gastrostomy tube insertions are accompanied by a fundoplication, yet little is understood about the surgical decision-making for these procedures. The objective of this study was to examine the decision-making process of surgeons about whether to perform a fundoplication in children already scheduled to have a gastrostomy tube placed.

METHODS

A written questionnaire of all pediatric surgeons at a major children's hospital was completed for each planned gastrostomy procedure over the course of 1 year; the questionnaire asked about various influences on the fundoplication decision: primary care and subspecialty physicians' opinions, patient characteristics, and parent opinions. Patient demographics and clinical characteristics from the medical record, as well as questionnaire responses, were summarized for each gastrostomy occurrence. We modeled the association of questionnaire responses and patient characteristics with the outcome of having a fundoplication.

RESULTS

We received questionnaires on 161 of 169 eligible patients (95%). A total of 52% of patients had fundoplication. Primary care physicians were involved in 44% of decisions, and when involved had "a lot" of influence on the fundoplication decision only 28% of time, compared with neonatologists (61%), hospitalists (44%), pediatric pulmonologists (42%), and pediatric gastroenterologists (40%). A total of 86% of patients had a subspecialist involved, and 28% had >1 subspecialist. A pH probe was performed in 7.5% of cases, and failed pharmacotherapy was noted by the surgeons in only 26.5% of the fundoplications performed.

CONCLUSIONS

The decision to do a fundoplication was rarely based on definitive testing or failed medical treatment. From the surgeon's perspective, subspecialists were more influential than primary care physicians, which is at odds with current concepts of the medical home.

A modified laparoscopic esophagogastric dissociation for severe bile reflux in a neurologically impaired child

The clinical scenario of a neurologically impaired child with a prolonged history of gastroesophageal reflux disease that underwent open Roux-en-Y gastrojejunostomy with subsequent development of severe symptomatic bile reflux is reported. The presentation, evaluation, and surgical management by laparoscopic revision to a modified esophagogastric dissociation are discussed.

Adverse outcomes associated with gastroesophageal reflux disease are rare following an apparent life-threatening event

OBJECTIVE

To evaluate for adverse outcomes associated with gastroesophageal reflux disease (GERD) following an apparent life-threatening event (ALTE) and potential risk factors of these outcomes.

STUDY DESIGN

Retrospective cohort study of well-appearing infants (<12 months) admitted for ALTE. Patients were followed for adverse outcomes associated with GERD (including aspiration pneumonia, failure-to-thrive, or anti-reflux surgery), second ALTE, or death. Risk factors evaluated included: age, prematurity, gender, previous event, diagnosis of GERD, gastrointestinal (GI) testing positive for gastroesophageal reflux, length of stay (LOS), and neurologic impairment diagnosed in follow-up.

RESULTS

Four hundred sixty-nine patients met inclusion criteria, mean age was 45 days, 110 (22%) were premature. Patients were followed for an average of 7.8 years; 3.8% of all patients had an adverse outcome associated with GERD. The only significant risk factors were a longer LOS, and development of neurological impairment. A diagnosis of GERD and positive reflux testing during the initial hospitalization were not associated with adverse outcomes associated with GERD.

CONCLUSIONS

Adverse outcomes associated with GERD are rare following an ALTE. Patients who developed neurological impairment and a longer initial LOS were at higher risk for developing these outcomes. Positive testing for gastroesophageal reflux during hospitalization for ALTE did not predict adverse outcomes associated with GERD.

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.

Trends in resource utilization by children with neurological impairment in the United States inpatient health care system: a repeat cross-sectional study

BACKGROUND

Care advances in the United States (US) have led to improved survival of children with neurological impairment (NI). Children with NI may account for an increasing proportion of hospital resources. However, this assumption has not been tested at a national level.

METHODS AND FINDINGS

We conducted a study of 25,747,016 US hospitalizations of children recorded in the Kids' Inpatient Database (years 1997, 2000, 2003, and 2006). Children with NI were identified with International Classification of Diseases, 9th Revision, Clinical Modification diagnoses resulting in functional and/or intellectual impairment. We assessed trends in inpatient resource utilization for children with NI with a Mantel-Haenszel chi-square test using all 4 y of data combined. Across the 4 y combined, children with NI accounted for 5.2% (1,338,590) of all hospitalizations. Epilepsy (52.2% [n = 538,978]) and cerebral palsy (15.9% [n = 164,665]) were the most prevalent NI diagnoses. The proportion of hospitalizations attributable to children with NI did not change significantly (p = 0.32) over time. In 2006, children with NI accounted for 5.3% (n = 345,621) of all hospitalizations, 13.9% (n = 3.4 million) of bed days, and 21.6% (US$17.7 billion) of all hospital charges within all hospitals. Over time, the proportion of hospitalizations attributable to children with NI decreased within non-children's hospitals (3.0% [n = 146,324] in 1997 to 2.5% [n = 113,097] in 2006, p<.001) and increased within children's hospitals (11.7% [n = 179,324] in 1997 to 13.5% [n = 209,708] in 2006, p<0.001). In 2006, children with NI accounted for 24.7% (2.1 million) of bed days and 29.0% (US$12.0 billion) of hospital charges within children's hospitals.

CONCLUSIONS

Children with NI account for a substantial proportion of inpatient resources utilized in the US. Their impact is growing within children's hospitals. We must ensure that the current health care system is staffed, educated, and equipped to serve this growing segment of vulnerable children.

A novel antireflux procedure: gastroplasty with restricted antrum to control emesis (GRACE)

PURPOSE

Nissen fundoplication is the most commonly performed operation to treat gastroesophageal reflux disease and vomiting in children with neurologic impairment. However, failure rates of Nissen fundoplication in this population are higher, and alternatives to Nissen fundoplication have technical and functional disadvantages. We hypothesize that the novel gastroplasty with restricted antrum to control emesis (GRACE) would be more effective than Nissen fundoplication at reducing emetic reflux.

METHODS

To compare the GRACE with Nissen fundoplication, 15 canine subjects were randomized to Nissen fundoplication or GRACE. All subjects underwent gastrostomy tube placement. Baseline gastric emptying, electrogastrography, and induced vomiting studies were performed. Nissen fundoplication or GRACE was then performed. Postoperatively, gastric emptying and vomiting studies were repeated.

RESULTS

Gastric emptying before and after antireflux procedures was not significantly different between groups. Both Nissen fundoplication (38%, P = .04) and GRACE (69%, P < .01) procedures prevented reflux compared with baseline. However, the GRACE procedure significantly reduced reflux when compared with Nissen fundoplication (P = .03).

CONCLUSIONS

In this canine model, GRACE appears to be significantly more effective than Nissen fundoplication at reducing emetic reflux. This novel procedure preserves gastric function and is well tolerated. The GRACE procedure may provide an alternative to Nissen fundoplication as a primary or repeat antireflux procedure for children with neurologic impairment.

Characteristics of hospitalizations for patients who use a structured clinical care program for children with medical complexity

OBJECTIVE

To describe the characteristics of hospitalizations for patients who use clinical programs that provide care coordination for children with multiple, chronic medical conditions.

STUDY DESIGN

Retrospective analysis of 1083 patients hospitalized between June 2006 and July 2008 who used a structured, pediatric complex-care clinical program within 4 children's hospitals. Chronic diagnosis prevalence (ie, technology assistance, neurologic impairment, and other complex chronic conditions), inpatient resource utilization (ie, length of stay, 30-day readmission), and reasons for hospitalization were assessed across the programs.

RESULTS

Over the 2-year study period, complex-care program patients experienced a mean of 3.1 ± 2.8 admissions, a mean length of hospital stay per admission of 12.2 ± 25.5 days, and a 30-day hospital readmission rate of 25.4%. Neurologic impairment (57%) and presence of a gastrostomy tube (56%) were the most common clinical characteristics of program patients. Notable reasons for admission included major surgery (47.1%), medical technology malfunction (9.0%), seizure (6.4%), aspiration pneumonia (3.9%), vomiting/feeding difficulties (3.4%), and asthma (1.8%).

CONCLUSIONS

Hospitalized patients who used a structured clinical program for children with medical complexity experienced lengthy hospitalizations with high early readmission rates. Reducing hospital readmission may be one potential strategy for decreasing inpatient expenditures in this group of children with high resource utilization.

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.

Outcomes of laparoscopic versus open fundoplication in children's hospitals: 2005-2008

BACKGROUND

Fundoplication is a common pediatric surgery, but little data comparing the laparoscopic approach with the open approach have been published.

OBJECTIVE

To compare infection rates, complication rates, length of stay, and cost for laparoscopic fundoplication versus open fundoplication among pediatric patients and to examine trends in utilization of laparoscopic fundoplication.

METHODS

We used the Pediatric Health Information System database to conduct a retrospective study of children (aged <19 years) admitted for a fundoplication between 2005 and 2008. Descriptive characteristics for those undergoing a laparoscopic and open fundoplication were compared. Multivariate regression with random effects specified at the hospital level was used to model the association between laparoscopic fundoplication and the outcomes.

RESULTS

Fifty-six percent of 7083 fundoplication admissions had laparoscopic fundoplication. Median length of stay was 4 days for laparoscopic and 10 days for open fundoplication. The median cost of laparoscopic fundoplication was $13 003 versus $22 487 for open fundoplication. Laparoscopic fundoplication was associated with a 24% and 51% reduction in the adjusted odds of infection and surgical complications, respectively. The proportion of fundoplications performed laparoscopically increased from 51% in 2005 to 63% in 2008 (P < .001), but there was no increase in the overall fundoplication rate.

CONCLUSIONS

In a large study of children's hospitals, laparoscopic fundoplication was associated with improved outcomes compared with the open procedure, even after adjustment for patient severity. Laparoscopic fundoplication has become the most common form of antireflux surgery in children over 1 year of age, but this has not been associated with an increase in the overall utilization of the fundoplication procedure. These data have important implications for clinical practice and surgical training.

Temporal association of polysomnographic cardiorespiratory events with GER detected by MII-pH probe in the premature infant at term

OBJECTIVES

The aim of the study was to examine temporal association (TA) between polysomnographic cardiorespiratory (CR) events and gastroesophageal reflux (GER) in premature infants with persistent CR events at >39 weeks postmenstrual age and determine whether the use of multichannel intraluminal impedance (MII)-pH probe improves sensitivity of the TA compared with pH probe alone.

PATIENTS AND METHODS

Seven infants born between 24 and 29 weeks' gestational age with persistent CR events at 39 to 48 weeks' postmenstrual age underwent a polysomnography with MII-pH probe. Symptom index (SI) and symptom-associated probability were calculated for diverse types of reflux and CR events. SI and a Fisher exact test with variable association windows were calculated for obstructive apnea (OA). Odds ratios for an OA given a reflux event and for a reflux event given an OA were determined.

RESULTS

With a Fisher exact test, a subject-specific association between MII events and OA was found in the 3 patients who required a fundoplication or had the worse clinical GER. Some level of TA was found with SI and symptom-associated probability in 6 of 7 infants. Association was found for pH > 4 and pH ≤ 4 reflux events. pH-only events with no change of MII had only a limited role in generating CR events.

CONCLUSIONS

TA between CR events and GER was found in a single-subject-level analysis in some infants with persistent CR events at term. This TA suggests a causal relation between CR and reflux events that was further strengthened by the clinical outcomes of each infant.

Patient characteristics associated with in-hospital mortality in children following tracheotomy

OBJECTIVES

To identify children at risk for in-hospital mortality following tracheotomy.

DESIGN

Retrospective cohort study.

SETTING

25 746 876 US hospitalisations for children within the Kids' Inpatient Database 1997, 2000, 2003 and 2006.

PARTICIPANTS

18 806 hospitalisations of children ages 0-18 years undergoing tracheotomy, identified from ICD-9-CM tracheotomy procedure codes.

MAIN OUTCOME MEASURE

Mortality during the initial hospitalisation when tracheotomy was performed in relation to patient demographic and clinical characteristics (neuromuscular impairment (NI), chronic lung disease, upper airway anomaly, prematurity, congenital heart disease, upper airway infection and trauma) identified with ICD-9-CM codes.

RESULTS

Between 1997 and 2006, mortality following tracheotomy ranged from 7.7% to 8.5%. In each year, higher mortality was observed in children undergoing tracheotomy who were aged <1 year compared with children aged 1-4 years (mortality range: 10.2-13.1% vs 1.1-4.2%); in children with congenital heart disease, compared with children without congenital heart disease (13.1-18.7% vs 6.2-7.1%) and in children with prematurity, compared with children who were not premature (13.0-19.4% vs 6.8-7.3%). Lower mortality was observed in children with an upper airway anomaly compared with children without an upper airway anomaly (1.5-5.1% vs 9.1-10.3%). In 2006, the highest mortality (40.0%) was observed in premature children with NI and congenital heart disease, who did not have an upper airway anomaly.

CONCLUSIONS

Congenital heart disease, prematurity, the absence of an upper airway anomaly and age <1 year were characteristics associated with higher mortality in children following tracheotomy. These findings may assist provider communication with children and families regarding early prognosis following tracheotomy.

A comparison of laparoscopic and open Nissen fundoplication and gastrostomy placement in the neonatal intensive care unit population

INTRODUCTION

The aim of this study was to compare outcomes after laparoscopic and open techniques for Nissen fundoplication and gastrostomy placement in the neonatal intensive care unit (NICU) population.

METHODS

The medical records for NICU inpatients who underwent laparoscopic and open Nissen fundoplication and gastrostomy placement from August 2002 to August 2008 were reviewed after Institutional Review Board approval. Each technique was compared with regard to operative time, estimated blood loss, postoperative 24-hour narcotic requirements, time to goal feeds, and complication rates. Analysis of variance was used to determine statistical significance. Data are quoted as mean +/- SEM.

RESULTS

Fifty-seven NICU patients underwent fundoplication and gastrostomy placement (25 laparoscopic and 32 open). The time to goal feeds was significantly shorter for the laparoscopic group (4.3 +/- 0.4 vs 6.1 +/- 0.6 days, P = .04). The 24-hour postoperative narcotic requirement was significantly lower in the laparoscopic group (0.24 +/- 0.05 vs 0.55 +/- 0.08 mg/kg, P = .007). Operation times (111 +/- 5 [open] vs 113 +/- 5 minutes, P = .76) and estimated blood loss (13 +/- 2 [open] vs 11 +/- 1 mL, P = .33) were comparable for both groups.

CONCLUSION

Laparoscopic and open techniques for Nissen fundoplication with gastrostomy placement are safe and appropriate treatment methods with equivalent operating times for the treatment of gastroesophageal reflux in the NICU population.

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.

Predictors of clinical outcomes and hospital resource use of children after tracheotomy

OBJECTIVES

The objectives are to describe health outcomes and hospital resource use of children after tracheotomy and identify patient characteristics that correlate with outcomes and hospital resource use.

PATIENTS AND METHODS

A retrospective analysis of 917 children aged 0 to 18 years undergoing tracheotomy from 36 children's hospitals in 2002 with follow-up through 2007. Children were identified from ICD-9-CM tracheotomy procedure codes. Comorbid conditions (neurologic impairment [NI], chronic lung disease, upper airway anomaly, prematurity, and trauma) were identified with ICD-9-CM diagnostic codes. Patient characteristics were compared with in-hospital mortality, decannulation, and hospital resource use by using generalized estimating equations.

RESULTS

Forty-eight percent of children were <or=6 months old at tracheotomy placement. Chronic lung disease (56%), NI (48%), and upper airway anomaly (47%) were the most common underlying comorbid conditions. During hospitalization for tracheotomy placement, children with an upper airway anomaly experienced less mortality (3.3% vs 11.7%; P < .001) than children without an upper airway anomaly. Five years after tracheotomy, children with NI experienced greater mortality (8.8% vs 3.5%; P <or= .01), less decannulation (5.0% vs 11.0%; P <or= .01), and more total number of days in the hospital (mean [SE]: 39.5 [4.0] vs 25.6 [2.6] days; P <or= .01) than children without NI. These findings remained significant (P < .01) in multivariate analysis after controlling for other significant cofactors.

CONCLUSIONS

Children with upper airway anomaly experienced less mortality, and children with NI experienced higher mortality rates and greater hospital resource use after tracheotomy. Additional research is needed to explore additional factors that may influence health outcomes in children with tracheotomy.

Position paper on laparoscopic antireflux operations in infants and children for gastroesophageal reflux disease. American Pediatric Surgery Association

The use of the laparoscopic approach to perform antireflux procedures has increased dramatically since its introduction in 1991. To date, no prospective randomized studies comparing open surgery to the minimal invasive approach in children have been reported. Many retrospective reviews and case series have demonstrated that laparoscopic antireflux procedures are safe and effective once the learning curve is achieved. This position paper is coauthored by the New Technology Committee of the American Pediatric Surgery Association. The goal is to discuss the ongoing controversies and summarize the available evidence to identify the risks and benefits of laparoscopic antireflux procedures.

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.

Effect of an isolated mild to moderate ischemic brain injury in the gastric emptying of liquids in rats

PURPOSE

To evaluate the effect of hypoxic-ischemic brain injury over the gastric emptying of liquids in rats.

METHODS

Fifty-two Wistar rats aged six weeks and weighing between 100 g and 150 g were divided in three groups. A Control group (C), a Sham group (S) undergoing sham procedure, and a Hypoxic-ischemic group (HI) consisting of 18 animals undergoing surgical ligature of the left carotid artery and exposure to hypoxic environment for three hours. Half of the animals were studied in the third day post-HI procedure (Early) and nine in the 14th day post-HI procedure (Late). Gastric emptying was evaluated by an infusion technique using fenolsulftalein as a marker.

RESULTS

After the HI procedure, all animals displayed left eyelid ptosis, and six animals showed minor sideway gait. Histological examination confirmed de brain injury in all animals from the HI group. There was no statistical significant difference among the mean gastric retention values of the three groups neither in the Early nor in the Late evaluation.

CONCLUSION

Isolated HI brain injury was not associated with delayed gastric emptying.

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.

Gastroesophageal reflux disease in children: efficacy of Nissen fundoplication in treating digestive and respiratory symptoms. Experience of a single center

Fundoplication has been commonly performed in neurologically impaired and normal children with complicated gastroesophageal reflux disease. The relationship between gastroesophageal reflux disease and respiratory diseases is still unclear. We aimed to compare results of open and laparoscopic procedures, as well as the impact of fundoplication over digestive and respiratory symptoms. From January 2000 to June 2007, 151 children underwent Nissen fundoplication. Data were prospectively collected regarding age at surgery, presence of neurologic handicap, symptoms related to reflux (digestive or respiratory, including recurrent lung infections and reactive airways disease), surgical approach, concomitant procedures, complications, and results. Mean age was 6 years and 9 months. Eighty-two children (54.3%) had neurological handicaps. The surgical approach was laparoscopy in 118 cases and laparotomy in 33. Dysphagia occurred in 23 patients submitted to laparoscopic and none to open procedure (P = 0.01). A total of 86.6% of patients with digestive symptoms had complete resolution or significant improvement of the problems after the surgery. A total of 62.2% of children with recurrent lung infections showed any reduction in the frequency of pneumonias. Only 45.2% of patients with reactive airway disease had any relief from bronchospasm episodes after fundoplication. The comparisons demonstrated that Nissen fundoplication was more effective for the resolution of digestive symptoms than to respiratory manifestations (P = 0.04). Open or laparoscopic fundoplication are safe procedures with acceptable complication indices and the results of the surgery are better for digestive than for respiratory symptoms.
