NASAL ENDOSCOPY (ID 1706)
G-O019 - USE OF A NOVEL ULTRATHIN GASTROSCOPE FOR UNSEDATED TRANSNASAL ENDOSCOPY IN CHILDREN AND ADULTS FOR EVALUATION OF UPPER GASTROINTESTINAL TRACT DISORDERS (ID 1371)
Abstract
Objectives and Study
Transnasal endoscopy (TNE) allows for endoscopic evaluation of the upper gastrointestinal tract while avoiding general anesthesia risk. In the pediatric age group, often bronchoscopes are used for performing TNEs, which precludes the evaluation of the stomach and duodenum due to shorter length and overall suboptimal visualization. In this study, we evaluated a novel ultrathin gastroscope (EvoEndo®) in children and adults.
Methods
This is a multicenter retrospective study between May and November 2022. There were a total of 6 participating sites in USA. Data was collected from electronic medical record. Primary outcome was safety and efficacy of EvoEndo® single use transnasal gastroscope. Secondary outcomes included procedure and encounter duration, and biopsy adequacy.
Results
Thirty-six patients were recruited. Indications included dysphagia, eosinophilic esophagitis and esophageal varices surveillance. Mean age was 16.1 years ± 6.1 (6-37 years) with male predominance (86.1%). 35/36 subjects underwent TNE for varying clinical indications and targeted anatomy. One procedure was aborted prior to initiation. 3 subjects underwent transnasal esophagoscopy (TN-Eso), 26 transnasal gastroscopy (TN-EG), and 3 transnasal esophagogastroduodenoscopy (TN-EGD). The procedure was successful in 91.4%. 3 procedures were unable to be completed. 50% underwent TNE for the first time. Biopsies were performed in all completed procedures except the 2 patients undergoing esophageal varices surveillance, and were adequate for histopathological analysis. Median procedure duration was 11 minutes (IQR: 7-16 minutes) and median visit duration was 33.5 minutes (IQR: 30-39 minutes). No significant adverse events occurred.
Conclusions
Ultrathin TNE using the EvoEndo® single use gastroscope was well tolerated and safe in the pediatric and adult age groups with a success rate similar to previously reported studies. User feedback noted EvoEndo’s single use gastroscopes provided improved visualization, further reach into the upper gastrointestinal tract, and a larger working channel allowing for diagnostic EGD in an efficient ambulatory setting without the need for general anesthesia.
