 Transnasal esophagoscopy (TNE) is a widely used tool both in the diagnosis and treatment of patients presenting complaints within the head and the neck. This is because this investigative adjunct examination provides the advantage of visualizing above the level of the cricopharyngeus muscle when compared to the more widely used esophagogastroduodenoscopy (EGD).  We have assessed if the implementation of TNE within a district general hospital (DGH) was feasible, and investigated if the resources of our patients could be better directed away from other investigations such as barium swallow and EGD in favor of this novel technique.

In Western countries, the incidence of esophageal adenocarcinoma has increased rapidly in parallel with its premalignant condition, Barrett esophagus (BE). Unlike colonoscopy, endoscopic screening for BE is not currently recommended for all patients; however, surveillance endoscopy is advocated for patients with established BE. Novel imaging and sampling techniques have been developed and investigated for the purpose of improving the detection of Barrett esophagus, dysplasia, and neoplasia. Read More

Eosinophilic esophagitis (EoE) is a recently recognised pathologic entity whose prevalence has risen significantly since first being described in 1993. Defined as a chronic, local immune-mediated disease with predominant eosinophil infiltration, it is nowadays the leading cause of dysphagia and food bolus impaction in children and young adults. Genetic and environmental risk factors, and especially food antigens, trigger the disease and are in the focus of investigation as avoidance can cure three quarters of patients. Read More

Background: Cricopharyngeus muscle dysfunction (CPMD) is a common cause of dysphagia. We employ a progressive series of three double-balloon dilations separated by 4-6 weeks between procedures as a primary treatment option. The purpose of this study was to evaluate subjective, functional and objective improvement in swallowing after three serial dilations for CPMD. Read More

Objectives: Dysphagia is a presenting symptom of both pharyngeal and oesophageal cancers. The referral pathway choice is determined by whether it is thought to be oropharyngeal or oesophageal, and this is in turn influenced by whether dysphagia is perceived to be above or below the suprasternal notch. We studied the concordance between the presence of pharynx-localised dysphagia (PLD) and the location of the underlying disease processes. Read More

Background: The advent of chip tip technology combined with advanced endoscopy has revolutionized the field of laryngology in the past decade. Procedures such as transnasal esophagoscopy, site-specific steroid injections, injection laryngoplasty and laryngeal laser treatment can now be performed in the office setting under local anaesthesia. Although In-Office Laryngeal Procedures (IOLPs) have become standard-of-care in many American and several Canadian centers, there are no guidelines regulating the practice of these procedures.

Globus may be a persistent symptom impairing patients' quality of life. Diagnostics and treatment are controversial but some globus patients may benefit from reassurance and attention. We investigated how globus symptoms change during a short-term follow-up without any treatment after an examination by an ear, nose and throat (ENT) physician and further diagnostic procedures.

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. Read More

Classic gastroenterological diagnostic tools have proven to be insufficient in identifying the causal relationship between extra-esophageal symptoms and presumed pathological reflux activity. Some new methodological approaches, such as functional endoscopy (video panendoscopy, VPE), are considered to be helpful. However, there are currently no data objectively verifying the success of this method. Read More

Introduction Transnasal oesophagoscopy is a relatively new method of examining the upper aerodigestive tract via the nasal passage as an outpatient procedure without the need for sedation. It has been shown to be a well tolerated, safe and accurate technique, that can therefore be used in the investigation of patients thought to have globus pharyngeus and other non sinister causes of dysphagia. Methods A total of 150 consecutive patients undergoing transnasal oesophagoscopy were analysed retrospectively. Read More
