Radiolabelled enema solution was administered to eight healthy subjects, both in fasted and fed states. Enema spreading was monitored over a 4-h period using gamma scintigraphy and colonic motility was recorded simultaneously using a pressure sensitive radiotelemetry capsule. The rate and extent of enema dispersion were unaffected by eating. Spreading could be correlated with colonic motility and was inhibited by aboral propulsion of the colonic contents.
给八名健康受试者在空腹和进食状态下均施用放射性标记的灌肠液。使用γ闪烁扫描术在4小时内监测灌肠液的扩散情况，并同时使用压敏无线电遥测胶囊记录结肠动力。灌肠液的扩散速率和程度不受进食的影响。扩散情况可能与结肠动力相关，并且会受到结肠内容物逆向推进的抑制。
