“…Indeed, even though they are based on slightly different engineering details, both these techniques aim to enhance the vascular network of mucosal lesions and thus differentiate them according to their biologic potential. As already demonstrated by Stanikova et al, NBI and SPIES appear to provide comparable outcomes with excellent diagnostic agreement between them [11]. Furthermore, coupling biologic endoscopy with contact endoscopes is a promising and inter-rater-reliable technique to further improve the diagnostic accuracy of intraoperative endoscopic evaluation [20,21].…”

“…In fact, many technical innovations and endoscopic tools have been recently developed to better evaluate such lesions in the pre-and intraoperative settings, including white light (WL) videoendoscopy and different kinds of biologic endoscopy, such as narrow band imaging (NBI) and the Storz professional image enhancement system (SPIES) [6,10,11]. These techniques, together with videolaryngostroboscopy (VLS) and saline infusion (SI) into the Reinke's space, help in obtaining detailed information about the tissue characteristics, vascular network, and superficial versus deep involvement of the different layers of the lamina propria by the lesion itself, thus allows for a tentative diagnosis (at least in terms of intraepithelial or more invasive disease) and adequate resection using a one-step excisional biopsy approach [9,12,13].…”

Background: The endoscopic appearance of glottic erythroleukoplakias is non-predictive of their histopathology, potentially ranging from keratosis to invasive squamous cell carcinoma (SCC). The aim of this study was to assess a comprehensive workup for the one-step diagnosis and treatment of mid-cord erythroleukoplakias, using CO2 laser excisional biopsy. Methods: We evaluated 147 untreated patients affected by 155 mid-cord erythroleukoplakias submitted to excisional biopsy by subepithelial (Type I) or subligamental cordectomy (Type II), across two academic institutions. Patients were evaluated by preoperative videolaryngostroboscopy, pre- and intraoperative videoendoscopy with biologic endoscopy (narrow band imaging, NBI, or the Storz professional image enhancement system, SPIES), either with or without intraoperative saline infusion into the Reinke’s space. Adequacy of treatment was the primary outcome. Results: The histopathologic diagnosis was keratosis in 26 (17%) cases, squamous intraepithelial neoplasia (SIN1-2) in 47 (30%), carcinoma in situ in 21 (14%), and SCC in 61 (39%) patients. The adequacy of treatment across the entire cohort was 89%. The intraoperative saline infusion procedure, facing not clearly suspicious lesions, raised the adequacy of treatment from 60% to 90% (p = 0.006). Conclusions: Excisional biopsy by Type I–II cordectomies, after a comprehensive diagnostic workup, should be accepted as an adequate and cost-effective treatment of unilateral mid-cord glottic erythroleukoplakias.

“…One of the recommendations by National Institute for Health and Care Excellence (NICE) 12 is to emphasize the role of NBI endoscopy as their strategy for an earlier tumour detection. As both NBI endoscopy and SPIES endoscopy methods are comparable in recognition and analysis of benign and malignant lesions 9 , SPIES endoscopy should also be recommended as one of the strategy for an earlier diagnosis of UADT tumours. Both NBI and SPIES endoscopy systems form an optimal strategy for preventing the progression of the cancer and improving the prognosis by earlier detection.…”

The diagnostic procedure for upper aerodigestive tract (UADT) tumours is by white light endoscopy (WLE) combined with biopsy. However, WLE has difficulty identifying minute epithelial changes which hinders early diagnosis. Storz Professional Image Enhancement System (SPIES) is designed to enhance the visualization of microvasculature on the mucosal surface and detect any epithelial changes. In this study, we aimed to evaluate the use of Ni endoscopic classification with SPIES endoscopy in the detection of UADT tumours. Fifty-nine patients with suspected UADT tumours underwent WLE followed by SPIES endoscopy. All the tumours were biopsied and sent for histopathological examination (HPE). The kappa index (κ) was used to evaluate the agreement between the methods. The level of agreement between SPIES using Ni classification and HPE showed almost perfect agreement as compared to moderate agreement between WLE and HPE. The sensitivity and specificity for WLE and HPE were 77.5% and 84.2% respectively with positive predictive value (PPV) of 91.2% and negative predictive value (NPV) of 64%. The sensitivity and specificity for SPIES endoscopy using Ni classification and HPE were 97.5% and 94.7% respectively with PPV of 97.5% and NPV of 94.7%. SPIES endoscopy using Ni classification is a valid tool for earlier tumour detection.

“…As a matter of fact, a great help in trying to distinguish high-from low-risk lesions (i.e., lesions with a low malignant potential like keratosis without atypia or mild dysplasia) may be derived from the systematic in-office use of bioendoscopic techniques such as the Narrow Band Imaging (NBI) by Olympus or the Storz Professional Image Enhancement System (SPIES), that have been repeatedly demonstrated to be superior to WL endoscopy alone in giving a valuable insight into the biologic behaviour of LDs [4]. As recently demonstrated by Stanikova and coworkers, both methods yield comparable outcomes in distinguishing benign/low-risk from malignant/high-risk lesions, with a sensitivity and specificity of 83% and 98%, respectively, for NBI, and 86% and 96% for SPIES [5]. Both techniques rely on a widely-applied classification of neoangiogenetic vascular changes that, when present, have the aspect, defined by Arens and coworkers, of "perpendicular vessels", indicative of a potentially malignant disease (from mild dysplasia upward) [6].…”

Purpose of review To give an overview of the current knowledge regarding the diagnosis, treatment, and follow-up of laryngeal dysplasia (LD) and to highlight the contributions of recent literature. Summary The diagnosis of LD largely relies on endoscopic procedures and on histopathology. Diagnostic efficiency of endoscopy may be improved using videolaryngostroboscopy (VLS) and bioendoscopic tools such as Narrow Band Imaging (NBI) or Storz Professional Image Enhancement System (SPIES). Current histological classifications are not powerful enough to clearly predict the risk to carcinoma evolution and technical issues such as sampling error, variation in epithelial thickness and inflammation hamper pathological examination. Almost all dysplasia grading systems are effective in different ways. The 2017 World Health Organization (WHO) system should prove to be an improvement as it is slightly more reproducible and easier for the non-specialist pathologist to apply. To optimize treatment decisions, surgeons should know how their pathologist grades samples and preferably audit their transformation rates locally. Whether carcinoma in situ should be used as part of such classification remains contentious and pathologists should agree with their clinicians whether they find this additional grade useful in treatment decisions. Recently, different studies have defined the possible utility of different biomarkers in risk classification. The main treatment modality for LD is represented by transoral laser microsurgery. Radiotherapy may be indicated in specific circumstances such as multiple recurrence or wide-field lesions. Medical treatment currently does not have a significant role in the management of LD. Follow-up for patients treated with LD is a fundamental part of their care and investigations may be supported by the same techniques used during diagnosis (VLS and NBI/SPIES).
