Telemedicine in Pediatric Gastroenterology: An Overview of Utility.

BACKGROUND: The availability of pediatric subspecialty services is a problem evident throughout the United States. Access to pediatric gastroenterology services, especially in rural areas, can be scarce. Telemedicine has been proposed as a tool capable of decreasing healthcare costs while extending medical care. OBJECTIVE: The purpose of this article is to review available literature regarding the utility of telemedicine as it applies to pediatric gastroenterology, specifically its role in eliminating healthcare disparities. METHODS: Research articles were identified through a PubMed search with key words focusing on telemedicine initiatives in pediatric gastroenterology, pediatric subspecialty, rural pediatric care, and adult gastroenterology. Studies were categorized based on the following areas of application: financial, time management, communication/community, and patient health and satisfaction. RESULTS: We reached the conclusion that evidence-supported trends in available literature provide a framework for pediatric gastroenterology telemedicine initiatives that can provide resource-sparing, community-enriching, and physician-improving services that ultimately serve to better patient health.

NASPGHAN Capsule Endoscopy Clinical Report.

Wireless capsule endoscopy (CE) was introduced in 2000 as a less invasive method to visualize the distal small bowel in adults. Because this technology has advanced it has been adapted for use in pediatric gastroenterology. Several studies have described its clinical use, utility, and various training methods but pediatric literature regarding CE is limited. This clinical report developed by the Endoscopic and Procedures Committee of the North American Society of Pediatric Gastroenterology, Hepatology and Nutrition outlines the current literature, and describes the recommended current role, use, training, and future areas of research for CE in pediatrics.

Management of ingested foreign bodies in children: a clinical report of the NASPGHAN Endoscopy Committee.

Foreign body ingestions in children are some of the most challenging clinical scenarios facing pediatric gastroenterologists. Determining the indications and timing for intervention requires assessment of patient size, type of object ingested, location, clinical symptoms, time since ingestion, and myriad other factors. Often the easiest and least anxiety-producing decision is the one to proceed to endoscopic removal, instead of observation alone. Because of variability in pediatric patient size, there are less firm guidelines available to determine which type of object will safely pass, as opposed to the clearer guidelines in the adult population. In addition, the imprecise nature of the histories often leaves the clinician to question the timing and nature of the ingestion. Furthermore, changes in the types of ingestions encountered, specifically button batteries and high-powered magnet ingestions, create an even greater potential for severe morbidity and mortality among children. As a result, clinical guidelines regarding management of these ingestions in children remain varied and sporadic, with little in the way of prospective data to guide their development. An expert panel of pediatric endoscopists was convened and produced the present article that outlines practical clinical approaches to the pediatric patient with a variety of foreign body ingestions. This guideline is intended as an educational tool that may help inform pediatric endoscopists in managing foreign body ingestions in children. Medical decision making, however, remains a complex process requiring integration of clinical data beyond the scope of these guidelines. These guidelines should therefore not be considered to be a rule or to be establishing a legal standard of care. Caregivers may well choose a course of action outside of those represented in these guidelines because of specific patient circumstances. Furthermore, additional clinical studies may be necessary to clarify aspects based on expert opinion instead of published data. Thus, these guidelines may be revised as needed to account for new data, changes in clinical practice, or availability of new technology.

Bowel preparation for pediatric colonoscopy: report of the NASPGHAN endoscopy and procedures committee.

Pediatric bowel preparation protocols used before colonoscopy vary greatly, with no identified standard practice. The present clinical report reviews the evidence for several bowel preparations in children and reports on their use among North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition members. Publications in the pediatric literature for bowel preparation regimens are described, including mechanisms of action, efficacy and ease of use, and pediatric studies. A survey distributed to pediatric gastroenterology programs across the country reviews present national practice, and cleanout recommendations are provided. Finally, further areas for research are identified.

Staple line ulcers: a cause of chronic GI bleeding following STEP procedure.

Intestinal failure (IF) results from a critical reduction in the functional intestinal mass resulting in dependence on total parenteral nutrition (TPN) for growth and survival. Short bowel syndrome (SBS) is the most common cause of intestinal failure in pediatrics. Following resection, the small bowel undergoes adaptation, a process wherein the bowel elongates and dilates in order to increase intestinal absorptive capacity. Small bowel dilatation can lead to dysmotility and small bowel bacterial overgrowth which may further enhance feeding intolerance. Bowel lengthening procedures are beneficial when there is significant dilatation of the small bowel and subsequent inability to advance enteral feeds. We describe a patient with intestine failure and short bowel syndrome due to gastroschisis who, presented with anemia and occult gastrointestinal bleeding, following Serial Transverse Enteroplasty procedure (STEP). Video capsule endoscopy (VCE) revealed multiple ulcerations at surgical staple sites throughout the distal 2/3 of the remaining small intestine which were the likely source of intestinal blood loss.

Non-IgE-mediated cow milk allergy is linked to early childhood clusters of commonly seen illnesses: a pilot study.

OBJECTIVE: There are few established diagnostic tools to define non-IgE-mediated food hypersensitivity reactions. Cow milk protein allergy (CMPA) is a multisystem disorder affecting the gastrointestinal, skin, and lower and upper airway systems. This link is frequently missed because of subspecialty evaluation of the multisystem effects individually. The authors hypothesize that a more global evaluation based on a simple scored questionnaire will reveal this link. METHODS: Over an 18-month period, children younger than 2 years with non-IgE-mediated CMPA were identified. A symptom questionnaire was developed and scored and also applied to a control population. The prevalence of symptoms in each group was compared and a cumulative score was determined. Symptoms evaluated included gastrointestinal, aerodigestive, lower airway, and skin symptoms. A positive response was scored 1 and a negative response scored 0. RESULTS: Significant differences in prevalence rates between CMPA and control populations were noted, particularly in aerodigestive symptoms. There were marked differences in cumulative score between populations (P < .001). The authors identified a cut-off score at which there was close to 80% sensitivity and 90% specificity for distinguishing CMPA from a control population. CONCLUSION: A global evaluation of multiple systems can be an important diagnostic tool in determining CMPA in infants.

Placement of pH probes during upper endoscopy: direct visualization is accurate.

BACKGROUND: Accurate catheter placement in children for esophageal pH monitoring is performed following an endoscopy using a mathematical formula followed by confirmatory radiograph. AIM: To determine if endoscopic visualization of the gastroesophageal junction can be used for sensor placement without the need for confirmatory radiograph. METHODS: Sixty-four catheters were placed using the Strobel formula method and 57 catheters were placed by visualization. RESULTS: With the formula method, 66% of children required probe adjustment compared with 7% when the probe was placed by direct visualization (p < .005). CONCLUSION: Placing pH sensors under direct visualization is accurate and reduces radiation exposure.

Antireflux surgery outcomes in pediatric gastroesophageal reflux disease.

OBJECTIVES: Antireflux surgery is performed frequently in children with gastroesophageal reflux disease (GERD). Few comparative studies exist which assess the indications for and short- or long-term outcome of open Nissen fundoplication (ONF) and laparoscopic Nissen fundoplication (LNF) for pediatric GERD. We investigated the frequency of reoperation and factors that might influence its occurrence. METHODS: We performed a retrospective, follow up cohort study of all children

The use of proton pump inhibitors in children: a comprehensive review.

Proton pump inhibitors (PPIs) belong to a group of chemically related compounds whose primary function is the inhibition of acid production in the final common metabolic pathway of gastric parietal cells. PPIs are highly selective and effective in their action and have few short- or long-term adverse effects. These pharmacologic features have made the development of PPIs the most significant advancement in the management of acid peptic related disorders in the last two decades. There are numerous published adult studies that describe the pharmacology, efficacy and safety of these anti-secretory agents; however, in the pediatric population, there are very few comparable studies, particularly multicenter studies with significant patient enrollment. In preparing this article, our aim was to perform a comprehensive review of the literature on the clinical pharmacology and use of PPIs in the pediatric population, and to briefly review some recent articles. Relevant literature was identified by performing MEDLINE/Pubmed searches from January 1990 to December 2001. Combinations of the following search terms were use to analyze these databases: proton pump inhibitor, children, pediatrics, gastroesophageal reflux disease (GERD), esophagitis, intestinal metaplasia, Helicobacter pylori, omeprazole, lansoprazole, pantoprazole, rabeprazole, esomeprazole, and safety. Abstracts from the 14th annual conference of the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) 2001, and the Disease and Digestive Week 2001, were also included in the review. All pediatric studies reviewed were limited to either omeprazole or lansoprazole. The dosage range used for the management of GERD and related disorders with lansoprazole was 0.73-1.66 mg/kg/day (maximum 30 mg/day). The dosage range for GERD management using omeprazole was 0.3-3.5 mg/kg (maximum 80 mg/day). The dosage range for omeprazole used for H. pylori was 0.5-1.5 mg/kg/day, with a maximum dosage of 40 mg/day, and lansoprazole-containing regimens for H. pylori eradication used dosages ranging from 0.6-1.2 mg/kg/day, with a maximum dosage of 30 mg/day. Few severe adverse events were reported with the use of either drug. Eradication rates for H. pylori were 56-87% for lansoprazole-based triple therapy, and 75-94% for omeprazole-based eradication regimens. To date, there are no published controlled trials of sufficient power comparing the efficacy of the five commercially available PPIs in children, for a variety of acid peptic diseases. Studies suggest that PPIs are highly effective for the management of GERD and related disorders, and are a critically needed component of triple therapy to eradicate H. pylori. PPIs have a very good tolerability profile in adults and children, but long-term tolerability studies are needed, particularly in the pediatric population. Multicenter studies are critically needed to evaluate the second-generation PPIs, to compare PPI efficacy to each other, and to assess the importance of developmental and genetic pharmacology of these drugs in children with acid-peptic disease.
