“…5 With the capability of direct and bright vision, a fibre laryngoscope is the preferred method of examination for excluding lesions on the postcricoid space and pyriform sinus mucosa. 6 However, our study showed that, using the routine method, the fibre laryngoscope could completely expose the postcricoid space in 0% of patients and the pyriform sinus in 18% of patients.…”

“…9) In addition to conventional WLE, many other "biologic endoscopy" methods (e.g., autofluorescence, contact endoscopy with vital tissue staining, and confocal endomicroscopy) have improved the rates of earlier detection of not only epithelial, but also vascular change in vocal cord. 10) Among them, narrow band imaging (NBI), which is an endoscopic imaging technique that emphasizes the mucosal microvasculature and identifies vascular alterations by placing narrow bandpass filters in front of a conventional white-light source to obtain tissue illumination at selected, narrow wavelength bands, is increasingly preferred and rec-ommended for examining in laryngeal lesion. 11) i-scan is a newly developed image enhanced endoscopy technology from PENTAX.…”

Background and Objectives：Detection of vascular abnormalities in vocal cord (VC) leukoplakia is important for the diagnosis of neoplastic change of the mucosa. The aim of this study was to investigate the value of i-scan in the differential diagnosis of VC leukoplakia based on visualization of abnormal vascular features. Material and Methods：Fifty-two patients with leukoplakia were enrolled in the study. Images of their larynx obtained using conventional white light endoscopy and an i-scan-enhanced endoscopy (Pentax DEFINA EPK-3000 Video Processors, with Pentax VNLJ10) were reviewed. The microvascular features of the lesions and vascular changes were analyzed and the results were compared with the histopathologic diagnosis. Results：Among the 52 leukoplakia patients, 7 (13.5%) patients had squamous hyperplasia, 10 (19.3%) mild dysplasia, 2 (3.8%) moderate dysplasia, 14 (26.9%) severe dysplasia, 4 (7.7%) carcinoma in situ, and 15 (28.8%) invasive squamous cell carcinoma on histopathologic examination. Using i-scan-enhanced endoscopy, abnormal vascular change with neoplastic neoangiogenesis was detected in most cases of malignant VC lesion [severe dysplasia : 9/14 (64.3%), carcinoma in situ: 2/4 (50.0%), and invasive squamous cell carcinoma : 11/15 (73.4%)]. Conclusion：i-scan-enhanced endoscopy is a useful optical technique for the diagnosis of VC leukoplakia. Our results suggest that i-scan may be a promising diagnostic tool in the early detection of laryngeal cancer.

“…The larynx and hypopharynx are both common sites for head and neck cancers in which patient survival depends greatly on early diagnosis [1]. The often vague and benign initial presenting symptoms of these cancers, such as cough and sore throat, make early detection particularly challenging [2].…”

“…Furthermore, laryngopharyngeal cancer morbidity remains high due to compromised function of essential aerodigestive and phonatory structures [3]. Jacobson et al suggest that the cost of head and neck cancers disproportionately burdens the US healthcare system when compared to other malignancies [4], yet despite this, there are no standardized screening tests for laryngopharyngeal cancers [1].…”

Objectives: We report and analyze eight cases in which patients were referred from gastroenterology (GI) to otolaryngology following esophagogastroduodenoscopy (EGD). We aim to provide specific examples of head and neck pathology encountered by gastroenterologists during upper endoscopy. Methods: A series of eight cases between 2016 and 2019 were analyzed by chart review. In each case, otolaryngology consultation was requested after an abnormality was noticed by a gastroenterologist during EGD. Subsequent laryngoscopy or bronchoscopy was performed in all cases allowing for image comparison. Select images comparing EGD to laryngoscopy findings are included as well as a literature review concerning the nature of communication between the two specialties. Results: Eight adult patients were referred to otolaryngology for abnormalities noted by a gastroenterologist during EGD at the following anatomic sites: soft palate (n=1), base of tongue (n=2), glottis (n=3), and interarytenoid mucosa (n=1). Additionally, a potential airway foreign body was noted on EGD which was ultimately determined to represent normal subglottic anatomy by bronchoscopy. Some 5/8 (63%) cases were considered true pathology while 3/8 (37%) represented normal anatomy or anatomic variants upon subsequent otolaryngologic evaluation. Conclusions: There is minimal literature regarding the nature of referrals from GI to otolaryngology following EGD. Our findings suggest that EGD offers a unique opportunity for early detection of otolaryngologic pathology. However, certain inter-specialty anatomic knowledge gaps were noted which contributed to occasional unnecessary referrals, procedures, and associated patient anxiety. We hope that the results of this study can inform future research aimed at improving communication and collaboration between the two specialties.

Visual evaluation of the larynx and hypopharynx during esophagogastroduodenoscopy: a safety and feasibility study

Abstract: Evaluation of the hypopharynx can be accomplished by gastrointestinal endoscopists at the time of EGD in the vast majority of patients in a safe manner while adding only about 35 s to the overall exam time.
