Experimental: Videoendoscopy with WL and NBI
The day before the laryngoscopy under general anesthesia (LGA), two endoscopies by two different physicians were performed for each patients and recorded: the first one with white light (WL) and the second one with NBI (NBI).
Procedure: WL and NBI
For each patient with a suspicion of squamous cell carcinoma of the oropharynx, hypopharynx or larynx for whom a laryngoscopy under general anesthesia (LGA) is expected benefit the day before a transnasal endoscopy with white lamp (WL) and NBI by two different operators. Suspected mucosal abnormalities showed by one or the two technics are reported in a table wich describes the different areas of the pharynx and the larynx. During the LGA, several biopsies are performed and identified (WL and/or NBI).
Several studies have already showed the interest of the use of NBI for the early diagnosis of malignancies of the upper aerodigestive tract. For all tumors, the most accurate evaluation of its limits is very important to perform the best strategy of treatment. If surgery seems to be the best option, surgical margins must be widely healthy. Despite the systematic transnasal flexible endoscopy with white lamp followed by laryngoscopy under general anesthesia (LGA) and tomodensitometric evaluation, surgical margins can be unhealthy (in situ carcinoma or dysplasia). We propose to evaluate if the use of the NBI could be useful to determine the superficial spread of squamous cell carcinomas in these locations.
To April 2013 to Mars 2015, all patients with a suspicion of squamous cell carcinoma of the oropharynx, hypopharynx or larynx and whom a LGA are expected, are included. The day before the LGA, two endoscopies by two different physicians were performed for each patients and recorded: the first one with white light and the second one with NBI. All results are noted on a schema. Superficial extension or synchronous lesions showed by NBI are analysed and compared with with lamp technic.
After surgery, surgical margins were evaluated and healthy margins were measured.
