Valuable Role

Narrow band imaging (NBI), in conjunction with magnifying endoscopy (ME), has arisen more and more attention in the area of advanced endoscopy. By enhancing the mucosal microvascular architecture and surface pattern, it is feasible to use ME-NBI to identify subtle changes associated with gastric inflammation, atrophy, intestinal metaplasia, and early gastric cancer. The new technique thus plays a valuable role in therapeutic decision-making, endoscopic treatment process, postoperative evaluation, and follow-up examination. To date, many criteria or evaluation method of ME-NBI has been proposed. This paper aims to summarize the various diagnosing classifications and the current clinical applications of ME-NBI in the stomach.

Узкополосная визуализация (NBI) – это недавно разработанная технология, цель которой – предоставить дополнительную эндоскопическую информацию пациентам с раком мочевого пузыря. Этот обзор посвящен диагностической точности и результату лечения с использованием цистоскопии NBI для лечения немышечного инвазивного рака мочевого пузыря. Текущие результаты показали улучшенную чувствительность цистоскопии NBI по сравнению с обычной цистоскопией в белом свете, хотя при использовании цистоскопии NBI сообщалось о более низкой специфичности и повышенном количестве ложноположительных результатов. Результаты лечения с использованием технологии NBI при трансуретральной резекции опухоли мочевого пузыря оказали положительное влияние, в то время как сообщалось о снижении количества остаточных опухолей и рецидивов опухоли при последующем наблюдении. В будущем применение технологии NBI может усовершенствовать протокол лечения и последующего наблюдения у пациентов с немышечно-инвазивным раком мочевого пузыря. / Narrow band imaging (NBI) is a newly developed technology aiming to provide additional endoscopic information for patients with bladder cancer. This review focuses on the diagnostic accuracy and treatment outcome using NBI cystoscopy for the treatment of nonmuscle invasive bladder cancer. Current results showed improved sensitivity of NBI cystoscopy compared to conventional white light cystoscopy, although lower specificity and increased false positive results were reported using NBI cystoscopy. The treatment outcome using NBI technology in transurethral resection of bladder tumor had a positive impact while decreased number of residual tumors and tumor recurrence at follow-up were reported. In the future, the application of NBI technology might refine the treatment and follow-up protocol in patients with non-muscle invasive bladder cancer. However, these large scale prospective studies are required to confirm the real cost-effectiveness of this new technology.

Background Cold polypectomy has been increasingly used to remove diminutive colorectal polyps. We evaluated the local recurrence rate of diminutive polyps at the 1-year follow-up after cold forceps polypectomy (CFP). Methods In a prospective, multicenter, observational cohort study, patients with diminutive colorectal polyps ( ≤ 5 mm) were treated by CFP using jumbo forceps followed by magnified narrow-band imaging (NBI). Patients were assessed for local recurrence at 1-year follow-up. Risk factors associated with local recurrence were analyzed using logistic regression analysis. Results Overall, 955 lesions were resected in 471 patients who completed the 1-year follow-up. The endoscopic complete resection rate was 99.4 %. Immediate and delayed bleeding occurred in 0.8 % and 0.2 % of cases, respectively, with no perforations observed. Local recurrence occurred in 2.1 % of cases at the 1-year follow-up. Univariable analyses indicated that polyps > 3 mm (P < 0.01) and immediate bleeding (P = 0.04) were significantly associated with local recurrence. A trend was observed for patients ≥ 65 years (P = 0.06) and fractional resection (P = 0.09). Multivariable analyses confirmed that lesions > 3 mm were significantly associated with local recurrence (odds ratio 3.4, P = 0.02). Conclusions CFP with jumbo forceps followed by NBI-magnified observation had a low local recurrence rate and is an acceptable therapeutic option for diminutive colorectal polyps. Although we recommend limiting the use of CFP with jumbo forceps to polyps ≤ 3 mm in size, future comparative studies are needed to make recommendations on cold polypectomy using either forceps or snares as the preferred approach for diminutive polyp resection.

Chirurgia Endoscopica

Negli ultimi venti anni la chirurgia endoscopica del basicranio ha osservato continui sviluppi tecnici e tecnologici. L’endoscopia 3D e l’ alta definizione (HD) 4K hanno fornito grandi vantaggi in termini di visualizzazione e di risoluzione spaziale. L’ ultra HD 4K, recentemente introdotta nella pratica clinica, determinerà i prossimi passi soprattutto nella chirurgica endoscopica del basicranio. I pazienti sono stati operati attraverso un approccio transnasale transfenoidale endoscopico, utilizzando un endoscopio Olympus NBI 4K UHD con ottica 4 mm 0 ° Ultra Telescope, lampada allo xeno 300 W (CLV-S400) predisposto per la tecnologia narrow band imaging (NBI) collegato con una videocamera ad un alta qualità unità di controllo (OTV-S400 - VISERA 4K UHD) (Olympus, Tokyo, Giappone). Due schermi, un 31 “Monitor - (LMD-X310S) e quello principale ultra-HD 55” a pollici ottimizzati per la riproduzione immagini UHD (LMD-X550S). In casi selezionati abbiamo usato un sistema di navigazione (Stealthstation S7, Medtronic, Minneapolis, MN, Stati Uniti). Abbiamo valutato 22 adenomi ipofisari (86,3% macroadenomi; 13,7% microadenomi). Il 50% non erano secernenti (NS), 22,8% GH, 18,2% ACTH, 9% PRLsecernenti. 3/22 erano recidive. Nel 91% dei casi abbiamo raggiunto la rimozione totale, mentre nel 9% la resezione subtotale. Un followup medio di 187 giorni, durata media del ricovero era 3,09 ± 0,61 giorni. Tempo chirurgico 128,18 ± 30,74 minuti. Abbiamo avuto solo 1 caso di fistola intraoperatoria a basso flusso senza ulteriori complicazioni nel follow up. Il 100% dei casi non ha richiesto emotrasfusione. La visualizzazione e l’alta risoluzione del campo operatorio hanno fornito una vista dettagliata di tutte le strutture anatomiche e patologie e permesso il miglioramento della sicurezza e l’efficacia della procedura chirurgica. Il tempo operatorio è stato simile a quello dell’endoscopio HD standard 2D e 3D, come la fatica fisica era paragonabile ad altri in termini di ergonomicità e peso.

Abstract Background and study aim The “resect and discard” strategy is a new paradigm for the management of small colorectal polyps that reduces the cost and effort related to pathological diagnosis after polypectomy. This retrospective study aimed to clarify the clinical outcome of the “resect and discard” strategy for small colorectal polyps. Patients and methods The clinical records were reviewed from 501 consecutive patients who underwent the “resect and discard” strategy for colorectal polyps smaller than 10 mm at our hospital between January 2008 and December 2010. All colorectal lesions were evaluated onsite under magnifying narrow-band imaging after careful conventional white-light imaging. In cases of low grade adenoma predicted with high confidence, colonoscopists selected the “resect and discard” option without formal histopathology. The mid-term outcomes were evaluated to validate the curability of the “resect and discard” strategy. Results The present study included 501 consecutive patients with 816 lesions. The mid-term outcomes were examined for 476 (95 %) patients who received follow-up for at least 1 year after undergoing the “resect and discard” strategy. The median observation period was 83 months (range 12 – 117 months). No patient died from colorectal cancer related to the procedure, resulting in a disease-specific survival rate of 100 %. There were no local and/or distant recurrences detected during follow-up. Conclusions The “resect and discard” strategy for small colorectal polyps under strict preoperative diagnosis achieves excellent mid-term outcome.
