Medium-term outcome of endoluminal gastroplication with the EndoCinch device in children

Therapeutic Upper Gastrointestinal Endoscopy in Pediatric Gastroenterology

This paper seeks to give a broad overview of pediatric upper gastrointestinal (GI) pathologies that we are now able to treat endoscopically, acquired or congenital, and we hope this delivers the reader an impression of what is increasingly available to pediatric endoscopists and their patients.

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.

Surgical management of pediatric gastroesophageal reflux disease

Gastroesophageal reflux (GER) is common in the pediatric population. Most cases represent physiologic GER and as the lower esophageal sphincter (LES) matures and a solid diet is introduced, many of these patients (>65%) experience spontaneous resolution of symptoms by two years of age. Those who continue to have symptoms and develop complications such as failure to thrive, secondary respiratory disease, and others are classified as having gastroesophageal reflux disease (GERD). Goals of GERD treatment include the resolution of symptoms and prevention of complications. Treatment options to achieve these goals include dietary or behavioral modifications, pharmacologic intervention, and surgical therapy. This paper will review the clinical presentation of GERD and discuss options for surgical management and outcomes in these patients.

Endolumenal therapies for gastroesophageal reflux disease

TIF Stretta and Endocinch all seem technically safe in well-selected patients including those with prior esophageal and gastric surgeries. Long-term effectiveness is being evaluated. Given the current enthusiasm for increasingly less invasive surgical techniques, the inertia for endolumenal therapies continues to grow. Other endolumenal therapies for Gastroesophageal reflux disease (GERD) have initiated trials. These pursue similar fundoplication or lower esophageal sphincter reconstruction using simpler techniques with fewer steps. Because all endolumenal approaches to GERD evolve, objective evaluation for symptom resolution and reduced esophageal acid exposure with improved esophagogastric physiology will remain a constant.

Managing gastroesophageal reflux disease in children: The role of endoscopy

Gastroesophageal reflux disease (GERD) is a growing problem in the pediatric population and recent advances in diagnostics and therapeutics have improved their management, particularly the use of esophago-gastroduodenoscopy (EGD). Most of the current knowledge is derived from studies in adults; however there are distinct features between infant onset and adult onset GERD. Children are not just little adults and attention must be given to the stages of growth and development and how these stages impact the disease management. Although there is a lack of a gold standard test to diagnose GERD in children, EGD with biopsy is essential to assess the type and severity of tissue damage. To date, the role of endoscopy in adults and children has been to assess the extent of esophagitis and detect metaplastic changes complicating GERD; however the current knowledge points another role for the EGD with biopsy that is to rule out other potential causes of esophagitis in patients with GERD symptoms such as eosinophilic esophagitis. This review highlights special considerations about the role of EGD in the management of children with GERD.

Pediatric gastroesophageal reflux disease

This article reviews the mechanisms responsible for gastroesophageal reflux disease (GERD), available techniques for diagnosis, and current medical management. In addition, it extensively discusses the surgical treatment of GERD, emphasizing the use of minimally invasive techniques.

Ensocopic-endoluminal therapies. A critical appraisal

Due to its large prevalence, gastro-oesophageal reflux disease is an ideal target for companies developing medical devices designed to cure reflux. Indeed, because medications leave part of the patients unsatisfied, there is a potential place for alternative therapies, capable of restoring an efficacious anti-reflux barrier, but without the drawbacks of surgery. For more than a decade, several novel endoluminal therapies were developed, clinically evaluated, put on the market and, for many of them, withdrawn due to economic considerations, lack of efficacy or complications. These therapies were designed to act on the gastro-oesophageal junction and reinforce mechanically the anti-reflux barrier by three different ways: suturing, radiofrequency energy application, or implantation of foreign materials. Most of the published data come from open uncontrolled studies with short-term enthusiastic results. There are a few randomized control trials assessing the true efficacy of these modalities, showing often less impressive results than the open studies did, due to a high placebo effect in mild gastro-oesophageal reflux disease. Although endoscopic treatment of gastro-oesophageal disease is still an interesting topic of investigation, one can draw some lessons from the recent experiences and foresee which place these techniques could find in the management of patients suffering from reflux.

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.

What is left of the endoscopic antireflux devices?

PURPOSE OF REVIEW

We critically analyze existing endoscopy-based interventions for gastroesophageal reflux disease (GERD). The focus is on the effectiveness of available procedures and to delineate goals for future research.

RECENT FINDINGS

Recent evaluations of the EndoCinch system reveal poor long-term results and no significant improvement over sham therapy due to poor apposition of mucosa with stitches. Recent studies with transoral incisionless fundoplication demonstrate improvement in GERD symptoms, quality of life, esophageal acid exposure, esophagitis, resting lower esophageal sphincter pressure and medication use. The SRS endoscopic stapling system creates a partial fundoplication wrap, and a preliminary study demonstrated improved symptoms and acid exposure. The Stretta system delivers radiofrequency energy to the gastroesophageal junction. A large prospective series demonstrates sustained improvement in GERD symptoms, quality of life and proton pump inhibitor therapy elimination after radiofrequency ablation at the gastroesophageal junction. A sham-controlled study showed improvement in symptoms at 6 months.

SUMMARY

EndoCinch plication requires further study and modification of technique before it can be recommended for general clinical use. Transoral incisionless fundoplication is a very promising procedure in its early stages of development. Further evaluation of procedure safety and durability is needed. Radiofrequency ablation therapy has been reintroduced and may have potential in patients with refractory GERD.

Recent advances and controversies in pediatric laparoscopic surgery

Children represent a unique group of patients who are likely to greatly benefit from minimally invasive surgery (MIS). The promise of less postoperative pain, smaller scars, shorter hospital stays, and a faster return to school continues to drive growth in this area. The development of pediatric-specific techniques and documentation of improved outcomes form a critical gateway to widespread application of pediatric MIS. A brief perspective on current approaches to MIS for pediatric congenital and acquired disease is provided in this report. Technical departures from standardized adult MIS and the rationale for their modification are highlighted.
