The benefits of transnasal endoscopy compared to conventional endoscopy in adolescents.

Abstract

Background and aim: Transnasal endoscopy (TNE) has been proven to reduce the need for intravenous anesthesia and the cost of the exams compared to conventional esophagogastroduodenoscopy (EGD) in adults. The objective of this study is to evaluate the benefits and the adverse effects of TNE in adolescents compared to conventional EGD.

Methods: We reviewed the pediatric patients from 2012 to 2022, who had undergone TNE at National Taiwan University Hospital due to epigastralgia. Age and gender-matched controls, who had undergone conventional EGD for epigastralgia at the same time, were also recruited.

Results: Totally 15 patients, aged between 12 and 20 years old, who had undergone TNE for epigastralgia at National Taiwan University Hospital were recruited as the study group. Another 60 age and gender-matched adolescents were also recruited in the control group. The needs of conscious sedation (9.3% vs 58.3%), hospitalization rate (13.3% vs 43.3%), the mean exam time (7.34 vs 9.96 min), and the cost of endoscopy (57.6 vs 93.2 USD) were significantly lower in the group of TNE as compared with the conventional EGD group. There was no difference in the percentage of complications, including dizziness, epistaxis, nausea, and vomiting, after procedures (P > 0.05.) CONCLUSIONS: TNE is a cost-effective exam and it also reduces the exposure to conscious sedation, the need for hospitalization and the exam time, making it a good choice for adolescents who are scheduled to undergo EGD for epigastralgia.
