  • ESD sedated esophagogastroduodenoscopy
  • TNE with biopsies can be adapted as an effective tool to monitor the esophageal, gastric, and duodenal mucosa of children with eosinophilic esophagitis (EoE) or other conditions of the upper gastrointestinal tract with the proper tools and techniques.

  • This technique can dramatically increase the safety and decrease cost in the care of children.
  • the present disclosure documents the development of the performance of TNE with biopsies in pediatric EoE.
  • ETnsedated TNE is an established technique in a number of pediatric and adult sub specialties, but it has not been used by pediatric gastroenterologists.
  • Applicants are particularly encouraged by their findings for several reasons. First, there was great interest in this procedure amongst patients and parents. Applicants only needed to screen 22 subjects to enroll the 21 subjects reported here. This is likely explained by the fact that the EoE patient population represents a very engaged, experienced, and educated population that is readily seeking alternative methods. Applicants are highly confident that this is a technically feasible procedure, and are further encouraged by its overall rapid success that was facilitated by a multidisciplinary pediatric team dedicated to the care of children with aerodigestive diseases and EoE. Applicants’ study provides strong support for larger studies to validate this approach that will provide novel insights into the natural history of EoE and significantly improve the lives of children with EoE in a safer, cost-effective, and efficacious manner.
  • the time at CHCO for a standard EGD is 3 hours compared to 60-90 minutes for the TNE, a time that included not only the TNE but also research protocol documentation.
  • This 3-hour procedure center time for EGD usually includes check-in, pre-operative evaluation by nursing, gastroenterology, and anesthesia, the procedure itself, recovery, and discharge instructions.
  • the 60-90 minute time for TNE in clinic included research documentation, pre-procedural documentation, the procedure itself, and discharge instructions. Most of these improvements in time reduction and increased satisfaction, noted above, are related to the effects of eliminating anesthesia or sedation for TNE. Not only does this practice seem to improve satisfaction of patients and parents, but there is also a significant likelihood it decreases the risk of adverse medication reactions, aspiration, and possible effects on the developing pediatric brain.
  • the third positive outcome of Applicants’ study relates to the integrity of the mucosal sample.
  • the technique’s effectiveness in evaluating mucosal esophageal samples Applicants found that the epithelial surface area needed for eosinophil count evaluation was not significantly different from the standard EGD 2.8 mm biopsy forceps compared to either of the TNE 2 mm or 1.2 mm biopsy forceps. This finding provides a high level of confidence that the sample procured at the time of TNE will have the same surface area compared to that obtained with the gold standard EGD biopsy forceps. The 2 mm forceps were also able to procure lamina intestinal.
  • TNE financial benefits of TNE include the fact that TNE incurred fewer charges and required less time away from work and school when compared to a standard sedated pediatric EGD.
  • the project demonstrated a significant 60.1% drop in charges.
  • the majority of this reduction in cost is related to the lack of anesthetic/anesthesiologist during TNE. The significance of this cannot be understated. For example, if Applicants’ institution were to perform 100 sedated EGDs per year for EoE at a hypothetical average, non-insurance adjusted charge of $9,390 dollars per general anesthesia-provided endoscopy encounter, this would accumulate $939,000 total charges per year for EoE.
  • TNE in pediatric gastroenterology for the evaluation of pediatric EoE is safe, preferred by patients and parents alike, and has the potential to dramatically reduce costs.
  • TNE would be measured as a highly effective practice in pediatric EoE management per Berwick’s description of the triple aim: the pursuit of improved experience of care, the health of populations should be improved, and the cost of per capita healthcare should be decreased.
  • Berwick DM Nolan TW, Whittington J. Health Aff ( Millwood) 2008;27:759-69.

  • KC pathologist
  • TNE procedures decreased as the endoscopists (JF, ED, JP, RD) became more experienced with TNE. (Table 2). The youngest child was eight years old and was able to tolerate the 4 mm endoscope without difficulty. Symptoms associated with the TNE included gagging and sore throat (Table 3). No adverse event was associated with any emergency department evaluation or unintended evaluation or treatment. One subject had a panic attack prior to the procedure but was still able to complete the TNE without any additional medication. She had a previous history of an anxiety disorder.
  • TNE findings revealed 11 subjects with normal esophagoscopy, nine with furrowing and one with furrowing and exudates. Visual findings correlated to the appropriate histologic findings in 85.7% of subjects.
  • Biopsy specimens revealed 12 normal biopsies, four with less than 15 eosinophils per hpf, and five with greater than 15 eosinophils per hpf.
  • Table 5, Image 1 No significant difference was identified when comparing total epithelial surface area of TNE biopsies to the biopsy surface area of the matched subject’s previous EGD.
  • Table 5 One subject who was initially evaluated at an outside institution did not have his previous biopsies available for analysis. Total epithelial surface area of mucosal biopsies samples from TNE forceps compared to those obtained with standard endoscopic forceps was not statistically different. (0.33 mm 2 +/- 0.09 vs. 0.38 mm 2 +/- 0.
