Transoral percutaneous endoscopic gas− trostomy (PEG) is not possible in some pa− tients due to difficulty in opening the mouth (e.g., in patients with head and neck cancers, oral submucous fibrosis, dental misalignment, and intermaxillary fixation). Transnasal endoscopy has been used for diagnostic upper gastrointestinal endoscopy and for placement of enteral feeding tubes [1, 2]. However, the...

Sinonasal foreign bodies are rare clinical entities. Their presence in the sinuses can originate complications, so their removal is always indicated. We present 3 cases of sinonasal foreign body, indicating their symptoms, imaging findings and surgical removal. Each patient was assessed with computerized tomography of the sinuses, rigid endoscopy, and then surgical removal. We confirmed the pre...

Recent developments have made ultrathin endoscopes available for routine esophagogastroduodenoscopy and also for unsedated transnasal observation (Shaker, 1994). Transnasal endoscopy is known to be less of a burden for patients (more tolerable) than transoral endoscopy and has benefits including fewer effects on respiratory and cardiovascular status and reduced recovery time after the procedure...

introduction: in recent years, the surgical management of angiofibroma has been greatly influenced by the use of endoscopic techniques. however, large tumors that extend into difficult anatomic sites present major challenges for management by either endoscopy or an open-surgery approach which needs new technique for the complete en block resection.   materials and methods: in a prospective obse...

Conventional gastroscopes have a diameter of 8.8-12 mm; ultrathin endoscopes have an outer diameter of 5.3-5.9 mm. We share our experience with 50 patients who underwent transnasal esophagogastroduodenoscopy using an ultrathin endoscope. The indications included endoscopyassisted nasogastric tube placement in 25 patients, tight lesions not negotiable with conventional endoscope in 9, restricted...
