Table 1 Accuracy, sensitivity, and specificity of preoperative endoscopic diagnosis for differentiation between C3 and C4/5 lesions
From: Current endoscopic diagnosis treatment strategy for superficial nonampullary duodenal tumours
Diagnostic techniques | Endoscopic diagnostic criteria | Cases | Accuracy (%) | Sensitivity (%) | Specificity (%) | Refs. |
|---|---|---|---|---|---|---|
White light endoscopy | A scoring system based on lesion diameter, color, macroscopic type, and nodularity | 134 | 86 | 88 | 79 | [6] |
ME-CV | A diagnostic algorithm based on magnifying mucin phenotypes including four patterns, convoluted, leaf-like, reticular/sulciolar, and colon-like pattern | 76 | 78.9 | 63.6 | 85.2 | [7] |
ME-NBI | Mucosal and vascular patterns including network, disappeared, white opaque substance and intrastructural vessels | 156 | 72 | 63 | 76 | [35] |
Endocytoscopy | An endocytoscopic classification based on the structural atypia, nuclear morphology and size | 93 | 86.7 | 87.7 | 85.4 | [11] |
