| 主な結果/Results | 44患者のSNADETsを評価した。visibility scoreは、LCIで3.53±0.59と、WLIの2.66±0.79、BLI brightの3.41±0.64よりも有意に高かった。また周囲の正常粘膜に比した病変の色差も、LCIで19.09±8.33と、WLIの8.67±4.81、BLI brightの12.92±7.95よりも有意に高かった。さらに、これらの結果はmilk white mucosa(MWM)の有無によらずに有意だった。 | For SNADETs of 44 patients, the visibility scores of LCI (3.53+-0.59) were significantly higher than those of WLI and BLI-b (2.66+-0.79 and 3.41+-0.64, respectively). The color differences between SNADETs and the adjacent normal duodenal mucosa in LCI mode (19.09+-8.33) were significantly
higher than those in WLI and BLI-b modes (8.67+-4.81 and 12.92+-7.95, respectively). |
