Oral aversion is a frequent diagnosis in the pediatric population. For a minority of children, feeding challenges rise to the level of requiring clinical evaluation and intervention. Determining the best evaluation and treatment plan can be challenging, but there is a consensus that treatment for children with a severe oral aversion involves an interdisciplinary approach. Within the team model, multiple strategies have demonstrated effectiveness, including sensorimotor skill building, behavioral modification, hunger provocation, and sensory integration therapy. This tutorial reviews the diagnostic and treatment process for a child with oral aversion, including identification of an underlying etiology, the medical and behavioral evaluation, and formulation of a treatment plan.

Enteral nutrition is the practice of delivering nutrition to the gut either orally or through a tube or other device. Many children are reliant on enteral feedings to either supplement their nutrition or as a complete source of their nutrition. Managing children on tube feedings requires a team of providers to work through such dilemmas as feeding schedules, weaning from tube feeding, sensory implications of tube feeding, treatment of pain or nausea associated with eating, oral-motor issues, and behavioral issues in the child and family. The purpose of the current review is to summarize the multidisciplinary aspects of enteral feeding. The multidisciplinary team consists of a variable combination of an occupational therapist, speech-language pathologist, gastroenterologist, psychologist, nurse, pharmacist, and dietitian. Children who have minimal oral feeding experience and are fed via a nasogastric or gastrostomy tube often develop oral aversions. Limited data support that children with feeding disorders are more likely to have sensory impairment and that early life pain experiences contribute to feeding refusal. There are inpatient and outpatient programs for weaning patients from tube feeding to eating. The parent-child interaction is an important part of the assessment and treatment of the tube-fed child. This review also points out many information gaps, including data on feeding schedules, blenderized tube feedings, the best methods for weaning children off enteral feedings, the efficacy of chronic pain medications with tube-fed children, and, finally, the necessity of the assessment of parental stress among all parents of children who are tube fed.

Objective To assess the role of amitriptyline in the effectiveness of an outpatient protocol for weaning medically complicated children from tube to oral feeding. Study design Twenty-one children seen in multidisciplinary outpatient feeding teams across four sites were recruited to a randomized placebo-controlled trial of a six-month outpatient treatment protocol with behavioral, oral-motor, nutrition and medication components. Results All of the children who completed the six-month program (73%) were weaned to receive only oral feeding, regardless of group assignment. The transition from tube to oral feeding resulted in decreases in BMI percentile and pain, some improvements in quality of life, and no statistically significant changes in cost. Conclusions Amitriptyline is not a key component of this otherwise effective outpatient, interdisciplinary protocol for weaning children from tube to oral feeding.

BackgroundIn adults, there is a consensus for standards to diagnose gastroparesis utilizing a gastric emptying study as the key diagnostic modality but there is no consensus for a standard in pediatrics. Additionally, some cost savings might be achieved if symptoms could be utilized to predict patients with gastroparesis. The aims of the current study were to confirm the sensitivity of a 4 h study in the pediatric population and to assess whether the severity of symptoms were predictive of delayed gastric emptying.StudyThis was a single site, two part study. In the first part, results were reviewed for all patients who had completed a 4-h, solid gastric emptying study over the course of a 3 year period. In the second portion of the study, participants scheduled for a gastric emptying study, completed a modified GCSI questionnaire.ResultsOut of a total of 109 participants, at 2 h, 14 participants (12.8%) had abnormal studies as compared to 26 (23.85%) participants who had abnormal studies at 4 h (p = .0027). Of the 95 participants with normal studies at 2 h, 15% (14/95) were abnormal at 4 h. There were no differences in symptom severity scores between those with slow and those with normal emptying at either 2 h or 4 h.ConclusionsOur study adds independent confirmation that extending studies from 2 to 4 h increases the diagnostic yield and should be the standard in children and adolescents as it is in adults.Electronic supplementary materialThe online version of this article (10.1186/s12876-019-0948-6) contains supplementary material, which is available to authorized users.
