Epiphrenic diverticulum develops when elevated esophageal intraluminal pressure causes herniation of the mucosa and submucosa through an area weakness in muscularis layer. Treatment must address both underlying dysmotility. The endoluminal functional lumen imaging probe allows measurement lower sphincter pressures to achieve ideal distensibility that prevents postoperative gastroesophageal refl...

We herein describe the first case of a high elderly patient with severe dysphagia in solids and liquids, caused by a huge epiphrenic diverticulum, who was treated with combined therapy of balloon dilation and botulinum toxin injection. Due to comorbid associated diseases the patient was unsuitable to withstand surgical or laparoscopic intervention. Treatment with botulinum toxin injection at th...

The epiphrenic esophageal diverticulum is a rare non-malignant condition that commonly associated with motility disorders. It would normally be treated surgically, but the advancement of endoscopy techniques, peroral endoscopic myotomy septotomy (D-POEM) has shown its benefits in coping symptoms. We present case 71-year-old woman increasing symptoms dysphagia, weight loss and imaging data showi...

BACKGROUND We report a unique case of a superficial esophageal cancer arising in a single diverticulum, diagnosed with magnifying image-enhanced endoscopy and then successfully treated by endoscopic submucosal dissection (ESD). CASE PRESENTATION A 66-year-old man with alcohol-related liver injury visited our hospital for endoscopy for investigation of varix. Esophagogastroduodenoscopy showed ...

A 34-year-old man was referred to our hospital because of chest pain and dysphagia that had lasted for 5 years. Endoscopy showed a tight esophagogastric junction (●" Fig.1). On high resolution manometry (Star Medical, Tokyo, Japan), the mean lower esophageal sphincter (LES) pressure and integrated relaxation pressure were 44.3 and 43.3mmHg, respectively (●" Fig.2). Type II achalasia was diagnos...
