为阐明慢性结肠炎等消化道疾病的结肠动力异常机制，对消化道疾病患者引例及对照组健康志愿者12名，在禁食12h后吞钡200mL，并于6．5h后拍摄卧位腹部X线照片，读片观察钡剂在各结肠段充盈及排空情况，测量各肠段纵径、横径、肠袋数及深浅，作数据统计。发现慢性结肠炎（ChronicColitis，CC）患者多数大便烂或便秘腹泻交潜，其大便难解或痛则欲便等大便行为改变症状亦多见。结肠X线照片显示，CC患者结肠横径变小、肠袋减少，钡剂排空异常增快。结肠X线影象异常可解释患者大便稀烂以及腹泻、痛则欲便等症状的部分病理生理机制，并可作为动力学指标，为临床诊治提供依据。
To clarify the abnormal colonic motility mechanism of gastrointestinal diseases such as chronic colitis, 12 healthy volunteers of patients with digestive diseases and control group were swallowed 200 mL after 12 h of fasting and photographed supine abdominal X Line photos, reading films were observed in each segment of the colon filling and emptying of the barium, measuring the length of the intestine, transverse diameter, number and depth of intestinal pocket for statistical data. Found that chronic colitis (ChronicColitis, CC) most patients with stool rotten or constipation diarrhea, the stool difficult to understand or pain and other stool behavior change symptoms are common. Colonic X-ray showed that CC patients with smaller transverse diameter of the colon, intestinal bags decreased, abnormal barium faster emptying. Abnormal X-ray of the colon can explain part of the pathophysiological mechanisms of patients with stool pulpy and diarrhea, pain and other symptoms, and can be used as a kinetic index to provide the basis for clinical diagnosis and treatment.
