本文用延时荧光电影摄影术观察了憩室病患者口服硫酸钡混悬液后横结肠不透明内容物的节段性变化。在其中一些中，分离不透明的肠内容物块的肌肉收缩被视为放松，然后以不同的空间关系重新形成，以憩室颈部为代表的肠壁上的固定点。在其他情况下，环收缩逐渐沿着肠壁移动，暂时阻塞他们所经过的任何憩室的颈部。肠内容物被认为是运输提前推进收缩在不同的速度和在任何一个方向。
Changes in the segmental pattern of opaque contents in the transverse colon among patients with diverticulosis were observed by means of time-lapse cinefluorography after ingestion of barium sulphate suspension. In some of them the muscular constrictions separating the opaque masses of bowel contents were seen to relax and later to re-form in a different spatial relationship to fixed points on the bowel wall represented by the necks of diverticula. In other instances ring contractions moved progressively along the bowel wall, temporarily occluding the necks of any diverticula they passed. Bowel contents were seen to be transported ahead of the advancing constrictions at varying rates and in either direction.
