Objectives: This report concerns office-based esophageal foreign body extraction using transnasal videoendoscopy and advantages of this intervention. Methods: A videoendoscope with a working channel for irrigation, air insufflation and forceps was used. The diameter of the videoendoscope tip was 5.3 mm. Transoral esophageal foreign body extraction using transnasal esophagoscopy was performed un...

The aim of this report is to present a technical detail of use in the management of an anorectal malformation (ARM). A boy with ARM and a fistula to the urethra was operated on with a posterior sagittal anorectoplasty (PSARP). Before the PSARP operation, a videoendoscopy was performed through the distal stoma down to the distal end of the rectum. The rectourethral fistula was identified and a g...

Hypercapnia produces a profound effect on respiratory drive and upper airway function to maintain airway patency. Previous work has evaluated the effects of hypercapnia on the sole arytenoid abductor, the posterior cricoarytenoid (PCA), using indirect measures of function, such as electromyography and direct nerve recording. Here we describe a novel method to evaluate PCA function in anesthetiz...
