Objective To explore X-ray features of systemic sclerosis's digestive tract. Methods The clinical and gastrointestinal X-ray angiogram materials of 23 patients with systemic sclerosis were retrospectively analysed. Results 20 cases of 23( 87％ )patients with systemic sclerosis gastrointestinal X-ray were abnormal. Among of them,6 cases were esophageal mild diastole and peristalsis were slowed; 12 cases were esophageal apparent expansion ; peristalsis was ahate or disappear completely ; barium was stranded , and mucosa of esophageal segment was unclear;5 cases were gastroesophageal reflux; gastric peristalsis of 2 cases were abate and emptying delay. Small intestinal tension of 6 patients was reduced, peristalsis became weak ,harium pass through small intestine prolonged, mucosal became disappear or added thick to show a spring shape and parts of enteric cavity were narrow. Conclusion Correct understanding of the digestive tract imaging features of systemic sclerosis ,has an important guiding significance for prompt understanding its gastrointestinal involvement of the incidence , degree and its efficacy evaluation , improvemend and prognosis which.%目的 探讨系统性硬化症(SSc)的消化道X线表现.方法 回顾性分析23例SSc的临床及消化道X线资料.结果 23例SSc消化道X线异常者20例(87%),6例食管轻度舒张,蠕动减慢,黏膜正常;12例食管明显扩张,蠕动微弱或完全消失,钡剂长时间在食管内停留,食管下段黏膜不清;5例有胃食管反流;2例胃的蠕动功能减弱,排空延迟;6例小肠张力降低,蠕动变弱,钡剂通过时间延长,黏膜消失或增粗呈弹簧状弛张,部分管腔狭窄.结论 正确认识SSc的消化道造影表现,对于及时了解其消化道受累的发生、程度及其疗效评价、改善预后,具有重要的指导意义.
