OBJECTIVES/HYPOTHESIS: Direct suspension laryngoscopic biopsy performed under general anesthesia is the conventional management for obtaining pathological diagnosis for neoplasms of the larynx, oropharynx, and hypopharynx. Since the development of distal chip laryngoscopy and digital imaging systems, transnasal flexible laryngoscopy tissue sampling has gained popularity as an office-based procedure. Additional assessment with narrow-band imaging (NBI) can help to increase the diagnostic yield...

OBJECTIVE: To compare the difference between white light (WL) and narrow-band imaging (NBI) endoscopy in evaluating patients who had reflux laryngitis and esophagitis. STUDY DESIGN: Retrospective review of medical records and endoscopic images. SETTING: Outpatient clinic. SUBJECTS AND METHODS: There were 102 consecutive patients with reflux esophagitis (mean age, 48 ± 11 years) who had office-based transnasal esophagoscopy (TNE) with WL and NBI views, including 60 men (59%) and 42 women (41%)...

OBJECTIVES/HYPOTHESIS: Image-enhanced endoscopy, such as narrow band imaging and the Storz Professional Image Enhancement System, have been increasingly used in patients with suspect lesions of the larynx and hypopharynx during preoperative and intraoperative assessment. STUDY DESIGN: In the present study, a contact endoscope was coupled with the systems of image-enhanced endoscopy, as to precisely distinguish the peculiar neoangiogenetic changes in inflammation, and precancerous and cancerous lesions of the larynx and hypopharynx...

Endoscopy is essential for the diagnosis and treatment of cancers derived from the larynx. However, a laryngoscope with conventional white light (CWL) has technical limitations in detecting small or superficial lesions on the mucosa. Narrow band imaging especially combined with magnifying endoscopy (ME) is useful for the detection of superficial squamous cell carcinoma (SCC) within the oropharynx, hypopharynx, and oral cavity. A total of 3675 patients who have come to the outpatient clinic and complained of inspiratory stridor, dyspnea, phonation problems or foreign body sensation, were enrolled in this study...

OBJECTIVES: Patients with head and neck squamous cell carcinoma (HNSCC) often develop second primary tumors in the upper aerodigestive tract. Early detection of synchronous esophageal squamous cell neoplasm (ESCN) is important because the prognosis of HNSCC can be affected by the statuses of second primary tumors. METHODS: In a prospective study, 308 patients with HNSCC were screened for synchronous ESCN between May 2010 and April 2012. All patients underwent conventional white-light endoscopic examination with Lugol chromoendoscopy and narrow band image...

BACKGROUND: The larynx and hypopharynx are common sites for head and neck cancer, which shares many risk factors with upper digestive tract disease. Patient survival with malignancies depends on stage at the time of diagnosis. Endoscopic screening of the hypopharynx is neither routinely performed in clinical practice nor has it been evaluated in a formal study. METHODS: This is a prospective pilot study of patients undergoing routine EGD. Demographic data were collected from patients prior to the procedure...

Narrow band imaging is considered a significant improvement in the possibility of detecting early mucosal lesion of the upper aerodigestive tract. Early detection of mucosal neoplastic lesions is of utmost importance for patients survival. There is evidence that, especially in patients previously treated by means of curative radiotherapy or chemoradiotherapy, the early detection rate of recurrent disease is quite low. The aim of this study was to prove whether the videoendoscopy coupled with NBI might help detect recurrent or secondary tumors of the upper aerodigestive tract...

OBJECTIVE: To investigate the value of narrow band imaging (NBI) endoscopy in the detection of unknown primary tumor site with cervical lymph node metastases of squamous cell carcinoma. METHODS: Fifty-three patients with cervical lymph node metastases of squamous cell carcinoma treated in our department between June 2009 and December 2011 were enrolled in this study. Their primary tumor site was not detected by routine computed tomography, magnetic resonance imaging and laryngoscopy...

PURPOSE OF REVIEW: Narrow band imaging (NBI) is a novel endoscopic technique using filtered wavelengths in order to enhance the microvascular abnormalities associated with the preneoplastic and neoplastic changes of the mucosal lining of the upper aerodigestive tract. The present review is focused on the use of NBI in the management of patients with laryngeal cancer. RECENT FINDINGS: The larynx and hypopharynx represent an ideal site for NBI application because their thin, nonkeratinized, stratified squamous epithelium permits optimal visualization of the subtle neoangiogenic changes associated with precancerous and neoplastic diseases, including benign processes like recurrent respiratory papillomatosis...

Direct suspension laryngoscopic biopsy of neoplasms in larynx, oropharynx, and hypopharynx was an arduous procedure in patients with a history of head and neck cancer and difficult airways. This preliminary study was aimed to report the efficacy and safety of a narrow band imaging-guided biopsy of this category by flexible laryngoscopy. This is a retrospective chart review study conducted in setting of tertiary referral centre. Nineteen consecutive head and neck cancer patients with difficulty in general anesthesia and rigid endoscopic approach due to trismus, craniofacial deformities, and/or limited neck extension after cancer therapy were referred for endoscopic biopsy of their suspicious lesions in larynx, hypopharynx, or parts of oropharynx...

Narrow-band imaging (NBI) is a novel optical technique that uses narrow bandwidth filters in a video endoscope system to improve the diagnostic capability of endoscopes in characterizing tissues. It is well known that early identification of neoplasia in the gastrointestinal tract using this technique might make it possible to reduce the suffering of patients caused by loss of function or severe complications after radical surgery. Several reports have introduced this system as a preoperative examination to evaluate the lateral spread of the neoplastic lesions in the oropharynx or hypopharynx...
