Transnasal endoscopy ease score "TNEase score" to evaluate patient tolerance of unsedated transnasal endoscopy

Transnasal endoscopy (TNE) with virtual reality (VR) distraction allows for unsedated pediatric upper endoscopy. Understanding the pediatric population that is successful with TNE is imperative for patient selection and experience. We developed a "TNEase Score" to assess patient tolerance from the physician's assessment. The aim of this study was to identify factors that influence patient's acceptance and tolerability of sedation-free TNE in pediatric patients undergoing the procedure. From March 2020 to April 2021, 110 TNEs were performed on subjects 5-22 years of age. The overall completion rate was 98.1%. Of these subjects, 66 subjects (60%) were graded by the gastroenterologist as TNEase Score 1 (with ease); 27 subjects (25%) were graded as TNEase Score 2 (minimal complaints); nine subjects (8%) were graded as TNEase score 3 (moderate complaints, required frequent reassurance); six subjects were graded as TNEase Score 4 (significant complaints and resistance); two subjects (2%) were graded as TNEase Score 5 (procedure terminated). Feasibility of TNE was significantly related to age, height, and whether the patient had undergone previous TNE. Thus, young age, shorter height, and first time TNE were significant predictors of higher TNEase score or difficulty tolerating TNE. Factors examined that did not predict higher TNEase score included gender, junior versus senior endoscopist, past medical history of anxiety, autism, attention-deficit/hyperactivity disorder (ADHD), or history of using a nasal spray at home. "TNEase score" allowed grading of the subject's experience and the majority of patients tolerated TNE with minimal complaints.

Protocolized awake secondary tracheoesophageal puncture with immediate voicing

Tracheoesophageal (TE) puncture with voice prosthesis placement is a common method for vocal rehabilitation in patients who have undergone total laryngectomy. Tracheoesophageal voice prosthesis (TEP) placement after laryngectomy, known as secondary TE puncture, is traditionally done in the operating room, using rigid esophagoscopy. Traditional secondary TEP placement carries a number of downsides including risks associated with general anesthesia, high cost, and technical challenges associated with anatomical variables. As a result, in-office secondary TE puncture has become an increasingly utilized procedure with many advantages but currently lacks standardization. Here, we describe a kit-based, awake, in-office secondary TE puncture with primary TEP placement technique. This technique calls for an endoscopic snare in the event there is difficulty passing the guidewire in the cranial trajectory. No surgical technique videos demonstrating in-office secondary TE puncture currently exist. Here, we present a video tutorial of our technique, breaking down the procedure into 10 steps from analgesia to voicing.

Comparison of transnasal esophagoscopy and sedated esophagogastroduodenoscopy in the assessment of laryngopharyngeal reflux

OBJECTIVE

Transnasal esophagoscopy (TNE) in the awake patient and esophagogastroduodenoscopy (EGD) in sedation are both used in the assessment of laryngopharyngeal reflux (LPR). The objective of this study was to compare these two endoscopic methods in contributing to the diagnosis of LPR.

METHODS

This study included 54 patients presenting with signs and symptoms suspicious for LPR, which were examined both by TNE and EGD. The contribution of each method to the diagnosis of LPR was evaluated separately and then compared with each other.

RESULTS

In detecting LPR, TNE showed a significant higher sensitivity (94% vs. 60%) and accuracy (93% vs. 59%) than EGD, but their specificity was equal (50% each). The most common pathologic findings in both methods were a hiatal hernia (70% vs. 48%) and gaping cardia (69% vs. 24%), followed by peptic esophagitis (41% vs. 24%).

CONCLUSION

The value of EGD is limited in the workup of LPR, as sedation tends to mask the subtle findings in this kind of reflux disease.

Virtual Dysphagia Evaluation: Practical Guidelines for Dysphagia Management in the Context of the COVID-19 Pandemic

With encouraging signs of pandemic containment nationwide, the promise of return to a full range of clinical practice is on the horizon. Clinicians are starting to prepare for a transition from limited evaluation of emergent and urgent complaints to resumption of elective surgical procedures and routine office visits within the next few weeks to months. Otolaryngology as a specialty faces unique challenges when it comes to the COVID-19 pandemic due to the fact that a comprehensive head and neck examination requires aerosol-generating endoscopic procedures. Since the COVID-19 pandemic is far from being over and the future may hold other highly communicable infectious threats that may require similar precautions, standard approaches to the clinical evaluation of common otolaryngology complaints will have to be modified. In this communication, we present practical recommendations for dysphagia evaluation with modifications to allow a safe and comprehensive assessment.

Unsedated In-office Transgastrostomy Esophagoscopy to Monitor Therapy in Pediatric Esophageal Disease

Monitoring therapy in esophageal inflammatory disorders such as eosinophilic esophagitis and reflux esophagitis often requires frequent endoscopic evaluation. We recently reported the effective use of unsedated in-office transnasal esophagoscopy that significantly decreased costs and anesthetic exposure associated with pediatric esophagoscopy in eosinophilic esophagitis. Here we report a series of pediatric patients with esophagitis with gastrostomy tubes who underwent unsedated transgastrostomy esophagoscopy (TGE) in an office setting. Nine patients (ages 16 months-21 years) tolerated TGE without significant adverse events. Biopsy specimens were adequate for evaluation. This series confirms that unsedated in-office TGE can be used to successfully obtain mucosal biopsies to monitor esophageal inflammatory conditions in children without the use of sedation.

Supragastric belch may be related to globus symptom - a prospective clinical study

BACKGROUND

The etiology of globus is poorly understood. It is controversial, whether gastroesophageal reflux disease (GERD) has a role in globus. To investigate the possible esophageal background of this symptom, we performed transnasal esophagoscopy (TNE), high-resolution manometry (HRM), and 24-h multichannel intraluminal impedance (MII) and pH monitoring on globus patients.

METHODS

Thirty consecutive patients were referred to Helsinki University Hospital, Department of Otorhinolaryngology - Head and Neck Surgery for treatment of globus; 24 consecutive patients with difficult reflux symptoms from the Department of Surgery served as controls. We compared the results of the patient groups in endoscopies, HRM, and 24-h MII-pH monitoring.

KEY RESULTS

In MII monitoring, globus patients had supragastric belch (6/20, 30% vs 1/24, 4%; p = 0.038) more often than controls. Total reflux time was higher in controls (p = 0.004), and they had more acid reflux events (p = 0.002) in MII, but between groups, the number of non-acid reflux events was similar. In pH monitoring, DeMeester score and total pH <4 time were higher in controls (P < 0.001). In HRM, the upper esophageal sphincter (UES) mean basal and residual pressures did not differ.

CONCLUSIONS & INFERENCES

Supragastric belch was more common in globus patients, suggesting the possible role of this condition in globus sensation. However, globus patients in this series had no acid or non-acid GERD or elevated UES pressure.

A New Trend in the Management of Esophageal Foreign Body: Transnasal Esophagoscopy

OBJECTIVES

(1) To analyze the outcomes of patients with esophageal foreign body managed by transnasal esophagoscopy. (2) To review the value of lateral neck X-ray.

STUDY DESIGN

Case series with chart review.

SETTING

Tertiary referral center, Shin Kong Wu Ho-Su Memorial Hospital, Taipei, Taiwan.

SUBJECTS AND METHODS

Lateral neck X-ray was used for initial screening in patients suspected of having an esophageal foreign body between 2007 and 2013. Rigid esophagoscopy was used as standard for further investigations before July 2010 and transnasal esophagoscopy after July 2010.

RESULTS

From January 2007 to June 2010, 43 patients who were suspected of having an esophageal foreign body under lateral neck X-ray received rigid esophagoscopy, 31 of whom were found to have an esophageal foreign body. From July 2010 to December 2013, 302 patients underwent transnasal esophagoscopy, and an esophageal foreign body was noted in only 52 of these patients. In the 302 patients who underwent transnasal esophagoscopy, the sensitivity and specificity of having an esophageal foreign body by lateral neck X-ray were 59% and 83%, respectively.

CONCLUSION

The introduction of transnasal esophagoscopy has changed the diagnosis and management for an esophageal foreign body. Transnasal esophagoscopy is a quick and safe procedure that can be performed under local anesthesia. Transnasal esophagoscopy could replace lateral neck X-ray to become the initial screening procedure and a useful treatment for patients with an esophageal foreign body.

Comparative acceptability of transnasal esophagoscopy and esophageal capsule esophagoscopy: a randomized, controlled trial in veterans

BACKGROUND

EGD screening for Barrett's esophagus (BE) is costly, with insufficient evidence to support its effectiveness.

OBJECTIVE

To compare acceptance and tolerability of 2 novel, office-based, endoscopic screening techniques done on nonsedated patients.

DESIGN

Randomized block study design with allocation concealment.

SETTING

Outpatient clinic setting at a Veterans Affairs medical center.

PATIENTS

A total of 184 veterans with or without GERD symptoms.

INTERVENTIONS

Transnasal esophagoscopy (TNE) or esophageal capsule esophagoscopy (ECE).

MAIN OUTCOME MEASUREMENTS

Acceptance and tolerability of TNE and ECE and effectiveness of BE screening.

RESULTS

Esophageal screening was accepted by 184 of 1210 (15.2%) veterans. The majority were men (96%) and African American (58%), with a mean (± standard deviation) age of 58.9 (± 8.1) years. Five TNE participants (5%) and 2 ECE participants (2%) refused the assigned procedure after randomization (P = .25). Eleven patients (12.6%) randomized to TNE crossed the minimal clinically important threshold for overall procedure tolerability, as opposed to no patients randomized to ECE (P = .001). Effectiveness of BE screening was not significantly different in both procedures (TNE vs ECE = 3.2% vs 5.4%; P = .47). Overall, BE was present in 8 of 75 white participants (10.6%) and in 0 of 107 African American participants (P < .001).

LIMITATIONS

The general veteran population may not reflect the screening population for BE.

CONCLUSION

Despite a small proportion of veterans expressing interest in esophageal screening, both TNE and ECE were feasible in the outpatient clinic setting and were accepted by >95% of participants who did express an interest. Screening was effective only in white participants. Moderate differences in tolerability between TNE and ECE notwithstanding, cost considerations along with availability of equipment and trained personnel should guide the modality to be used for BE screening.

Utility of the transnasal esophagoscope in the management of chemoradiation-induced esophageal stenosis

OBJECTIVE

This study aimed to describe management of esophageal stenosis after chemoradiation therapy for head and neck squamous cell carcinoma (HNSCC), with particular emphasis on techniques and outcomes with the use of the transnasal esophagoscope (TNE) in the office as well as operating room settings.

METHODS

Retrospective analysis of all patients with esophageal stenosis following head and neck cancer radiation, with or without chemotherapy, and managed with TNE-assisted esophageal dilation over a 5-year period. Preoperative and postoperative swallowing function were assessed objectively with the Functional Outcome Swallowing Scale (FOSS; ranging from score 0, a normal diet, to score 5, complete dependence on nonoral nutrition).

RESULTS

Twenty-five patients met inclusion criteria. The mean pretreatment FOSS score was 4.4, whereas the mean posttreatment FOSS score was 2.7 (Wilcoxon signed-rank test, P<.001). Prior to dilation, 16 patients were completely gastrostomy-tube dependent (FOSS 5), of whom 12 (75%) were able to tolerate oral nutrition for a majority of their diet following treatment according to our protocol. No complications were noted.

CONCLUSION

Dysphagia following chemoradiation therapy for HNSCC is often related to esophageal stenosis. With the aid of TNE, we have developed a successful treatment strategy for esophageal stenosis with improved success rates.
