“…The sensitivity of M-CE in diagnosing dSMC ranged from 63 % to 94 % [16,20], while the specificity ranged from 86 % to 100 % [15,21]. On pooled analysis, the sensitivity and specificity of M-CE in diagnosing invasion depth in early CRCs were 84 % (95 %CI 76 % -89 %; I 2 = 76.9 %) and 97 % (95 %CI 94 % -99 %; I 2 = 90.2 %), respectively (▶ Fig.…”

Narrow-band imaging in the diagnosis of deep submucosal colorectal cancers: a systematic review and meta-analysis

Magnifying endoscopy with narrow-band imaging (M-NBI) has been widely used in the differential diagnosis of deep submucosal colorectal cancers (dSMCs) from superficial submucosal cancers (sSMCs) and intramucosal neoplasms. We aimed to pool the diagnostic efficacy of M-NBI and compare it with that of magnifying chromoendoscopy (M-CE) in diagnosing colorectal dSMC. PubMed, EMBASE, and the Cochrane Library were searched to identify eligible studies. Meeting abstracts were also searched. A bivariate mixed-effects binary regression model was used in the meta-analysis to calculate the pooled diagnostic efficacy of M-NBI and compare it with that of M-CE in the diagnosis of dSMC. Subgroup analyses and meta-regression were conducted to explore sources of heterogeneity. We included 17 studies: 14 full texts and 3 meeting abstracts. The pooled sensitivity, specificity, and area under the summary receiver operating characteristic curve (AUC) with 95 % confidence intervals (CIs) in diagnosing dSMC were 74 % (66 % - 81 %; I = 84.6 %), 98 % (94 % - 99 %; I = 94.4 %), and 0.91 (0.88 - 0.93), respectively, for M-NBI. The pooled sensitivity, specificity and AUC (95 %CI) were 84 % (76 % - 89 %; I = 76.9 %), 97 % (94 % - 99 %; I = 90.2 %), and 0.97 (0.95 - 0.98), respectively, for M-CE. M-NBI had lower sensitivity ( < 0.01) than M-CE with similar specificity ( = 0.32). Subgroup analyses and meta-regression indicated that endoscopic diagnostic criteria, study type, endoscope type, risk of index test bias, and histopathological diagnostic criteria might be the sources of heterogeneity. M-NBI and M-CE had comparable specificities in diagnosing dSMC, but the sensitivity of M-NBI was slightly lower than that of M-CE.

“…They compared FICE-ME findings with those from NBI-ME by analyzing 692 colorectal lesions (55 non-neoplastic, 524 adenomas, 90 intramucosal cancers, 23 invasive cancers) treated by endoscopic resection or surgery, which were initially detected by conventional colonoscopy and then observed by NBI-or FICE-ME. NBI and FICE findings were classified according to presence of a pit-like structure (white zone) and according to appearance of a vascular area due to the collapsing of microvessels surrounding the pit network; histology served as the gold standard, and sensitivity, specificity, and accuracy were 50 %, 100 %, and 98.3 %, respectively, in the diagnosis of invasive cancer [57]. Finally, FICE-ME was also used in an interesting multicenter trial involving nine colonoscopy experts from eight endoscopic units located in Brazil, Japan, and Venezuela, which attempted to validate observations correlating capillary vessel patterns of colorectal lesions with hyperplastic polyps, adenomas, and carcinomas [58].…”

The 18th United European Gastroenterology Week (UEGW), held in Barcelona in October 2010, marked a return to the traditional "stand-alone" UEGW meeting after the previous year's combined congress format of GASTRO 2009. Various abstracts on endoscopic subjects were presented, providing a unique opportunity for those interested in gastrointestinal endoscopy to not only become acquainted with the latest advancements and research in the field, but also to meet and exchange experiences with colleagues from all over the world. This report will focus mainly on oral presentations, with a few selected poster presentations, which will be reviewed briefly in the context of recent literature in the respective fields of gastrointestinal endoscopy.

“…Die Histologie diente als Goldstandard. Sensitivität, Spezifität und Genauigkeit betrugen 50 %, 100 % und 98,3 % bei der Diagnostik eines invasiven Karzinoms[57]. FICE-ME wurde auch in einer interessanten Multizenterstudie eingesetzt, die 9 Koloskopexperten aus 8 Endoskopieeinheiten in Brasilien, in Japan und Venezuela einbezog.…”
