Three hundred sixty clinical cases which presented with or without mechanical intestinal obstruction were evaluated in order to discover reliable quantitative and qualitative criteria for pre-surgical x-ray diagnoses. It was discovered that small bowel distension of above 1.0 (ratio) together with obvious gas fluid level is usually indicative of small bowel obstruction, while large bowel distension of above 1.5 (ratio) together with obvious gas fluid level is usually indicative of large bowel obstruction. Subsequent surgery confirmed that there exists a correlation between the degree of small bowel distension seen on radiographs prior to surgery and the actual small bowel distension secondary to small bowel obstruction measured during surgery. The present results may be diagnostically useful in the radiological differentiation of mechanical intestinal obstructions from other abdominal conditions.
为了找到可靠的术前X线诊断的定量和定性标准，对360例有或无机械性肠梗阻的临床病例进行了评估。结果发现，小肠扩张比例大于1.0且伴有明显气液平面通常提示小肠梗阻，而大肠扩张比例大于1.5且伴有明显气液平面通常提示大肠梗阻。后续手术证实，术前X线片上所见的小肠扩张程度与手术中测量的继发于小肠梗阻的实际小肠扩张程度之间存在相关性。本研究结果可能有助于在放射学上鉴别机械性肠梗阻与其他腹部疾病。
