BACKGROUND Esophagogastroduodenoscopy is an often-used and safe diagnostic method in gastroenterology. Transnasal esophagogastroduodenoscopy is now an established addition to the endoscopic instrumentarium. Although the two examination methods can be used alongside each other, there is a lack of studies on the comparability of the localization data obtained with the transoral and transnasal met...

We report a rare but severe complication of routine transnasal esophagogastroduodenoscopy (EGD). The tip of a transnasal endoscope was locked in a bent position. Since the bent tip was unable to be returned to a neutral position, the snare from another endoscope inserted transorally was used to straighten it, which allowed the transnasal endoscope to be withdrawn with only mild injury to the ga...

The large majority tumours affecting are mainly primary neoplasm or from direct extension adjacent region; metastatic tumour extremely rare. Most metastases originate carcinoma inferior to clavicle, including renal, breast, lung, and prostate. incidence sphenoid sinus even We describe a rare case FTC tract, mimicking ...

OBJECTIVES Accidental displacement of endosseous implants into the maxillary sinus is an unusual but potential complication in implantology procedures due to the special features of the posterior aspect of the maxillary bone; there is also a possibility of migration throughout the upper paranasal sinuses and adjacent structures. The aim of this paper is to review the published literature about ...

Background Unsedated transnasal esophagoscopy (TNE) may offer a less expensive, mobile alternative to sedated esophagogastroduodenoscopy (EGD) for evaluations of reflux related complications. Comparisons of imaging quality by these methods are lacking. Methods Two reviewers evaluated videos of TNE and EGD procedures, performed during a community randomized study comparing endoscopic techniques....

BACKGROUND Maxillary sinus inverted papilloma entails medial maxillectomy and is associated with high incidence of recurrence. OBJECTIVE To study the impact of prior surgery on recurrence rate after transnasal endoscopic medial maxillectomy. METHODOLOGY Eighteen patients with primary and 33 with recurrent maxillary sinus inverted papilloma underwent transnasal endoscopic medial maxillectomy...

dysphagia over a 2-month period. Transnasal endoscopy with an ultrathin endoscope (Fujinon EG-530N; Fujinon, Wayne, New Jersey, USA) was used. An ulcerative tumor was found in the middle esophagus (●" Fig. 1), and the biopsy revealed squamous cell carcinoma. A feeding tube was placed over a guidewire. A chest computed tomography (CT) scan was performed the next day to evaluate the esophageal ca...

OBJECTIVE To explore the vidian nerve anatomy by endoscopy and paranasal sinus computed tomography (CT) to elucidate the appropriate surgical approach based on preoperative CT images. DESIGN Retrospective analysis. SETTING Tri-Service General Hospital, National Defense Medical Center, Taipei, Taiwan, Republic of China. PATIENTS Sixty-seven patients underwent 106 endoscopic vidian neurecto...
