A 55-year-old man with alcoholic liver cirrhosis was admitted to hospital with tarry stools. Videoendoscopy examination on admission revealed blood oozing from the greater curvature of the gastric body (ectopic varices). Endoscopic ultrasonography and computed tomography were used in making the diagnosis. Endoscopic band ligation (EBL) was performed for the bleeding site of these varices. The p...

(HSV) are compared. Two of them are based on tracking the maximum of the cross-correlation function of two images; two are based on minimization of the L 2 –norm and L 2-like distance between two images ; and the other two make use of the peak present in the cross-power FFT-based spectrum of two images. All six methods are applied to compensate the motion, at the sub-pixel level, of the endosco...

Fiberoptic examination of the pharynx under drug-induced sleep is a test that helps to detect the areas of vibration and collapse in patients with sleep-disordered breathing. This article is a review of the available literature on the subject, aimed at helping otolaryngologists to understand the procedure and to resolve some controversies surrounding it.

Aim of this prospective preliminary study was to assess effectiveness and reliability of autofluorescence endoscopy in the diagnosis of laryngeal lesions, in particular, evaluating whether it could represent an improvement in comparison to standard endoscopy alone. A total of 81 laryngeal biopsy specimens, taken from 46 consecutive patients who underwent intra-operative endoscopic assessment in...

INTRODUCTION The authors performed videolaryngoscopy during the preoperative anesthesia clinic evaluation of a patient with chronic dyspnea, stridor, and a previous hemilaryngectomy scheduled to undergo a series of orthopedic surgery procedures for an infected knee arthroplasty. The findings proved crucial for determining airway management. CASE PRESENTATION A 68-year-old man presented to the...
