| Abstract | 「要旨」健常人および食道切除後の嚥下機能を明らかにするため, シンチグラフィを用いて咽頭から上部食道への嚥下機能の定量的な評価を試みた. 方法は, 185MBqの99mTc過テクネチウム酸塩液10mlを坐位および臥位で嚥下させ, 口腔・頸部上部・頸部下部・胸部上部食道に設定した関心領域における時間放射能曲線を作成し検討した. 健常人12例では, 嚥下された液体の通過は臥位では坐位に比して有意に遅延していた. しかし, 健常人では臥位においても嚥下された液体は平均0.8秒で頸部下部食道に, 1.4秒で胸部上部食道に達していた. 食道切除後生理的な後縦隔経路で再建された症例の嚥下機能は健常人と差はなかった. しかし, 非生理的な胸骨後経路で再建された例では嚥下機能に明らかな障害が認められた. 食道シンチグラフィは嚥下機能を鋭敏にかつ定量的に評価するうえで有用である. |

| Abstract | [Summary]To evaluate the function of deglutition quantitatively, radionuclide transit in the and upper esophagus was examined. Ten ml of water containing 185 MBq 99mTc pertechnetate was put into the mouth and isotopic counts were measured every 0.2 second in the oral cavity, upper and lower cervical esophagus, and upper mediastinum. The subjects were studied twice, once while sitting and once supine. Esophageal transit was evaluated with time-activity curves obtained in each region of interest. In twelve healthy volunteers transit of the radionuclide was significantly delayed in supine position compared with sitting position. Even while the subject was supine, the radionuclide was propelled into the lower cervical esophagus in 0.8 second and upper mediastinum in 1.4 second in the healthy volunteers. In the patient, who had reconstruction of the esophagus through posterior mediastinum, radionuclide transit was not different from that of healthy volunteers. Whereas in the patient, who had the reconstruction through retrosternal space, the transit was remarkably delayed. The esophageal scintigraphy was safe and sensitive enough to evaluated the function of deglutition quantitatively. |
