Abstract
PURPOSE Existing guidelines provide weak recommendations on the surgical management of nutritional problems in children. The objective was to design a management pathway to address the best nutritional surgery (NS) procedure in a given patient. METHODS Retrospective analysis of children treated at our department from January 2015 to December 2019. The sample was divided into two groups according to presence or absence of neurological impairment (NI). Patients with NI (Group 1) were classified in three subgroups based on presenting symptoms: A-Dysphagia without gastroesophageal reflux (GER); B-GER with or without dysphagia; C-Symptoms associated with a delayed gastric emptying. RESULTS A total of 154 patients were included, 111 with NI. One-hundred-twenty-eight patients underwent only one procedure. Complications and mortality were superior in Group 1. In subgroup A, isolated gastrostomy was the first NS in all patients. In subgroup B most of patients were subjected to a Nissen fundoplication, while in 5 cases total esophagogastric dissociation (TEGD) was the first intervention. Considering the entire sample, 92.3% patients who underwent a TEGD did not require further procedures. CONCLUSION NS encompasses various procedures depending on presenting symptoms and neurological status. A management flowchart for these patients is proposed.

Abstract
Purpose: Fundoplications are a common operation in the pediatric population. This study aims to explore outcomes comparing laparoscopic versus open operative techniques. Methods: From 2010 to 2014 the Nationwide Readmissions Database was used to identify patients aged 0-18 years who underwent a fundoplication. Propensity score matched analysis was performed based on 87 covariates. Demographics, hospital factors, readmissions, and complications were compared by surgical technique (laparoscopic versus open). Results: There were 4411 patients (47% female) who underwent fundoplication via laparoscopic (69%) versus open (31%) technique. Gastrostomy tubes were placed in 75% of patients also undergoing fundoplication. Newborn made up 64% of the cohort, with 47% of newborns having cardiac anomalies and 96% being premature. Open fundoplications were more likely to be performed in newborns (72% versus 61%) and those in the lowest income quartile compared to laparoscopic (41% versus 31% P < .001), both P < .001. The readmission rate was 20% within 30 days and 38% within the year, with 15% admitted to a different hospital. Only 14% of readmissions were elective. Open fundoplication was associated with more unplanned readmissions (94% versus 84%), conversion to gastrojejunostomy tube (11% versus 5%) along with major (5% versus 3%) and minor (8% versus 2%) complications compared to the laparoscopic approach, all P < 0.001. Conclusion: The majority of fundoplications are being performed in newborns and are being done laparoscopically, which are associated with lower complication and postoperative readmission rates compared to open fundoplications.

J Surg Res 2020; 256:251-257. [PMID: 32712438 DOI: 10.1016/j.jss.2020.06.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2020] [Revised: 06/04/2020] [Accepted: 06/16/2020] [Indexed: 11/16/2022]
Abstract
BACKGROUND Infants with congenital heart disease (CHD) often require the placement of a gastrostomy button to ensure proper nutrition. Some also require a Nissen fundoplication (NF) to further improve nutrition capabilities in the setting of reflux, however, the clinical and diagnostic imaging characteristics that support NF are variable. The aims of this study were as follows: (1) identify the factors associated with NF in patients with CHD and (2) determine the incidence of NF complications in patients with CHD. METHODS All patients with CHD who underwent cardiac repair and subsequent creation of a gastrostomy at a single institution between 6/1/2013 and 9/1/2018 were included. We then identified which patients underwent NF. RESULTS Two-hundred fifty-seven CHD patients who had a gastrostomy button placed after CHD repair, with 17% undergoing a simultaneous NF or an NF at a later time. The presence of acyanotic heart disease, neurologic comorbidities, and vocal cord dysfunction was not univariately associated with a higher likelihood of NF. On multivariable model, only prematurity was significantly associated with NF (P = 0.022). Abnormal findings on imaging studies (upper gastrointestinal series, gastric emptying studies, motility studies, upper endoscopies, swallow studies, and pH probe studies) were not associated with an NF (all P's > 0.05). The overall complication rate was 23%. CONCLUSIONS Prematurity was the only factor associated with an NF. Surprisingly, cyanotic heart disease, neurologic comorbidities, age at first cardiac surgery, and vocal cord dysfunction were not associated with an NF. We identified an area for quality improvement at our institution given the lack of standardized work-up for the NF in this high-risk population.

Abstract
Background Gastroesophageal reflux is a common disorder in pediatrics. Clinicians should be familiar with the proper evaluation and management of this condition. Objective To provide an update on the current understanding, evaluation, and management of gastroesophageal reflux in children. Methods A PubMed search was performed with Clinical Queries using the key term ‘gastroesophageal reflux’. The search strategy included meta-analyses, randomized controlled trials, clinical trials, observational studies, and reviews. The search was restricted to the English literature and the pediatric age group. Results Regurgitation is the most frequent symptom of gastroesophageal reflux and is present in nearly all cases. Gastroesophageal reflux occurs normally in infants, is often physiological, peaks at 4 months of age, and tends to resolve with time. Gastroesophageal reflux disease occurs when gastric contents reflux into the esophagus or oropharynx and produce troublesome symptom(s) and/or complication(s). A thorough clinical history and a thorough physical examination are usually adequate for diagnosis. When the diagnosis is ambiguous, diagnostic studies may be warranted. A combined esophageal pH monitoring and multichannel intraluminal esophageal electrical impedance device is the gold standard for the diagnosis of gastroesophageal reflux disease if the diagnosis is in doubt. In the majority of cases, no treatment is necessary for gastroesophageal reflux apart from reassurance of the benign nature of the condition. Treatment options for gastroesophageal reflux disease are discussed. Conclusion In most cases, no treatment is necessary for gastroesophageal reflux apart from reassurance because the condition is benign and self-limiting. Thickened feedings, postural therapy, and lifestyle changes should be considered if the regurgitation is frequent and problematic. Pharmacotherapy should be considered in the treatment of more severe gastroesophageal reflux disease for patients who do not respond to conservative measures. Proton pump inhibitors are favored over H2-receptor antagonists because of their superior efficacy. Antireflux surgery is indicated for patients with significant gastroesophageal reflux disease who are resistant to medical therapy.

Abstract
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.

Abstract
Gastroesophageal reflux disease (GERD) is a common condition in infants. Symptoms from pathologic GERD include regurgitation, irritability when feeding, failure to thrive, and respiratory problems. Treatment typically starts with dietary modifications and postural changes. Antireflux medications may then be added. Indications for operative management in neonates and infants include poor weight gain, failure to thrive, acute life-threatening events, and continued respiratory symptoms. Laparoscopic Nissen fundoplication has become the standard of care for surgical treatment of children with GERD. In this procedure, the fundus of the stomach is wrapped 360° posteriorly around the lower esophagus.

Abstract
Gastroesophageal reflux disease (GERD) is a very common condition and affects approximately 7-20% of the pediatric population. Symptoms from pathological GERD include regurgitation, irritability when feeding, respiratory problems, and substernal pain. Treatment typically starts with dietary modifications and postural changes. Antireflux medications may then be added. Indications for operative management in the pediatric population include failure of medical therapy with poor weight gain or failure to thrive, continued respiratory symptoms, and complications such as esophagitis. Laparoscopic Nissen fundoplication has become the standard of care for surgical treatment of children with GERD. The key technical aspects of laparoscopic Nissen fundoplication include creation of an adequate intra-abdominal esophagus, minimal dissection of the hiatus with exposure of the right crus to identify the gastroesophageal junction, crural repair, and creation of floppy, 360° wrap that is oriented at the 11 o׳clock position.

Abstract
AIM OF THE STUDY Present the outcomes of patients younger than 2years who underwent laparoscopic fundoplication, highlighting the failure rate and need for redo fundoplication. METHODS Retrospective review of patients <2years who underwent laparoscopic fundoplication between January 2009 and December 2014. MAIN RESULTS 458 infants younger than 2years underwent laparoscopic fundoplication in the 6-year period (360 Nissen, 77 Toupet and 21 Thal fundoplications). Median age at surgery was 5 (1-23) months. Median follow-up was 3 (1-6) years. The conversion rate was 0.87% (4 of 458 cases). Patients did not undergo routine studies to assess the incidence of postoperative GER but were instead followed clinically. Failure of the fundoplication was determined when a patient was unable to gain weight and/or protect the airway while receiving gastric feedings because of GER. The failure rate in our experience was 2.6% (12 redo out of 458 cases [11/360 Nissen, 1/77 Toupet and 0/21 Thal]). All failed cases occurred because of migration of the fundoplication, confirmed preoperatively by a contrast study. Median time between the initial fundoplication and the redo was 13 (5-27) months. There were no failures within a contemporaneous group of 101 patients <2years who underwent open fundoplication. CONCLUSION The need for a redo fundoplication after a laparoscopic fundoplication was an uncommon event in our experience (12 of 458 cases). Our results contrast with published studies that report higher failure rates. Case volume per surgeon may explain in part the dissimilar results among studies. LEVEL OF EVIDENCE III.

Abstract
Despite aggressive antimicrobial therapy, many respiratory pathogens persist in the lung, underpinning the chronic inflammation and eventual lung decline that are characteristic of respiratory disease. Recently, bile acid aspiration has emerged as a major comorbidity associated with a range of lung diseases, shaping the lung microbiome and promoting colonisation by Pseudomonas aeruginosa in Cystic Fibrosis (CF) patients. In order to uncover the molecular mechanism through which bile modulates the respiratory microbiome, a combination of global transcriptomic and phenotypic analyses of the P. aeruginosa response to bile was undertaken. Bile responsive pathways responsible for virulence, adaptive metabolism, and redox control were identified, with macrolide and polymyxin antibiotic tolerance increased significantly in the presence of bile. Bile acids, and chenodeoxycholic acid (CDCA) in particular, elicited chronic biofilm behaviour in P. aeruginosa, while induction of the pro-inflammatory cytokine Interleukin-6 (IL-6) in lung epithelial cells by CDCA was Farnesoid X Receptor (FXR) dependent. Microbiome analysis of paediatric CF sputum samples demonstrated increased colonisation by P. aeruginosa and other Proteobacterial pathogens in bile aspirating compared to non-aspirating patients. Together, these data suggest that bile acid signalling is a leading trigger for the development of chronic phenotypes underlying the pathophysiology of chronic respiratory disease.
