BACKGROUND & AIMS Extended esophageal endoscopic submucosal dissection (ESD) is highly responsible for esophageal stricture. We conducted a comparative study in a porcine model to evaluate the effectiveness of adipose tissue-derived stromal cell (ADSC) double cell sheet transplantation. METHODS Twelve female pigs were treated with 5 cm long hemi-circumferential ESD and randomized in two group...

BACKGROUND/AIMS Achalasia is a primary motility disorder of esophagus. Many parameters represent esophageal function and morphologic changes, but their interrelationship is not yet established. We hypothesized that esophageal body would need to generate unusual pressure to empty the food bolus through the non-relaxing lower esophageal sphincter in patients with achalasia; therefore, higher is t...

BACKGROUND AND PURPOSE Acute suppurative neck infections associated with branchial fistulas are frequently recurrent. In this study, we describe the imaging findings of acute suppurative infection of the neck caused by a third or fourth branchial fistula (pyriform sinus fistula). METHODS Imaging findings were reviewed in 17 patients (11 female and six male patients, 2 to 49 years old) with ne...

INTRODUCTION Tracheoesophageal fistula (TEF) is an abnormal communication between the trachea and the esophagus that can lead to respiratory distress and/or feeding problems. The majority of infants with a TEF also have esophageal atresia, both of which are usually repaired concurrently. Unfortunately, recurrent fistulae occur in 3% to 12% of case series and can be difficult to repair. A recurr...

rare complication caused by a variety of conditions. Along with trauma and malignancy, cuff-related tracheal injury has become the most common etiology. As few cases have been reported, with different clinical presentations and solutions for treatment, the results and conclusions are difficult to interpret [1–3]. This report describes a new, practical approach to the treatment of large tracheoe...

Ingestion of foreign bodies is a common problem in the otolaryngology practice. Reports of extraluminal migration of the foreign bodies from the upper aerodigestive tract are rare. Penetration and extraluminal migration of ingested foreign bodies may cause severe vascular and suppurative complications, even death. We report a 4-year-old girl who presented with a mass and partial extrusion of a ...

BACKGROUND Transesophageal echocardiography is widely used in cardiac surgery. Transesophageal echocardiography probe insertion and manipulation can injure the esophagus. CASE PRESENTATION A 76-year-old Asian man was admitted to our hospital for coronary artery bypass graft revascularization surgery. A right carotid endarterectomy was successfully performed 2 days before coronary artery bypas...

An 82-year-old man was admitted to our hospital due to dysphagia. Barium esophagography showed the esophagus to have a corkscrew appearance (Picture 1). Esophagogastroduodenoscopy also showed similar findings (Picture 2). Given these typical imaging findings, he was diagnosed with diffuse esophageal spasm (DES), although esophageal manometry for a definite diagnosis could not be performed due t...

Although the barium esophagography can exclude the vascular ring, the direct visualization of the thoracic aorta is not possible [1]. Echocardiography can provide a good depiction of the mediastinal vessels and associated cardiovascular malformations. However, it is limited in patients with poor acoustic windows, and visualization of the trachea and esophagus can be difficult or impossible. Cat...

Zenker's diverticulum (ZD), also known as cricopharyngeal, pharyngoesophageal or hypopharyngeal diverticulum, is a rare condition characterized by an acquired outpouching of the mucosal and submucosal layers originating from the pharyngoesophageal junction. This false and pulsion diverticulum occurs dorsally at the pharyngoesophageal wall between the inferior pharyngeal constrictor and the cric...
