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.
This review highlights some of the recent advances in pediatric esophageal and antroduodenal motility testing including indications, preparation, performance, and interpretation of the tests. This update is the second part of a two part series on manometry studies in children (first part was on anorectal and colonic manometry [Neurogastroenterol Motil. 2016;29:e12944]), and has been endorsed by the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) and the American Neurogastroenterology and Motility Society (ANMS).
The current findings provide evidence that clinicians who work with children and adolescents with IBD may benefit from modifying their approach to nonadherence screening. Asking about youth involvement in remembering daily medications may be more informative than asking them to recall their medication-taking behavior over the last week in identifying those at highest risk for nonadherence.
We studied spontaneous gastroesophageal reflux (GER)-induced esophageal distension using ultrasound imaging and its role in the genesis of esophageal symptoms before and during esomeprazole therapy. Ten controls and 10 GER disease (GERD) patients were studied by combined impedance, esophageal pH, manometry, and ultrasonography before and during esomeprazole therapy. Physiological data and symptoms were recorded for 2 h following a standardized meal. From ultrasound images, the esophageal cross-sectional area (CSA) at the peak of GER-induced distension was determined and compared between controls vs. patients, symptomatic vs. asymptomatic GER episodes, and before vs. during esomeprazole in GERD patients. The mean lumen CSA is greater in the patients than controls (271 +/- 71 mm(2) vs. 163 +/- 56 mm(2), P = 0.001) but not different among asymptomatic reflux episodes, and those associated with regurgitation (290 +/- 110 mm(2)) or heartburn (271 +/- 67 mm(2)). Eight chest pain episodes associated with reflux revealed a tendency toward larger mean esophageal distension (459 +/- 40 mm(2)) compared with asymptomatic reflux (268 +/- 70 mm(2), P = 0.058). Following esomeprazole treatment, most GER episodes were nonacidic and asymptomatic except in two patients in whom cyclical reflux was associated with large esophageal distensions. Esomeprazole did not alter the lumen CSA during GER. Esophageal distension is greater in the GERD subjects compared with controls; however, it is unlikely that the GER-induced distension of the esophagus plays a significant role in the genesis of heartburn sensation. Esomeprazole therapy does not alter the GER-induced distension of the esophagus.
OTT studies may be helpful to predict which children should be referred for CM studies. Normal OTT studies may predict normal colon manometry; however, abnormal OTT studies may not predict abnormalities in colonic manometry in children with chronic constipation. Therefore, patients with slow transit marker studies should be assessed by colon manometry to evaluate colon neuromuscular integrity.
In this retrospective study, MRCP was sensitive and specific in identifying anatomic abnormalities of the pancreatobiliary tree in children. MRCP should be considered before direct CP to evaluate anatomic abnormalities of the pancreatobiliary tree.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
