CT检查能够预测阑尾炎的严重程度

根据近期对计算机断层扫描检查的研究结果，研究人员设计了一个模型来预测急性阑尾炎的严重程度。

Mayo诊所的科学家检查了105例年龄在15岁～69岁进行腹部CT检查后3天内接受阑尾切除手术的患者资料。对CT扫描结果与急性阑尾炎实际严重程度进行了比较。研究证实了CT结果与急性阑尾炎阑尾实际病变有相关性。这些结果被用来设计一个模型，当与额外CT检测联合使用的时候，能够帮助确定高度疑似急性阑尾炎的治疗方案。

研究人员得出结论，研究达到了在不远的将来设计出预测模型的目标，能够根据疾病的组织学严重程度预测来对此类患者进行分层。这些研究结果为随后的前瞻性临床试验提供了基础，将使用预测性分层来确定手术干预时间的选择。

这项研究发表在2004年11月的《外科档案期刊》上。
 
CT Can Predict Severity of Appendicitis
 
Based on recent computed tomography (CT) findings, researchers have devised a model to predict the severity of acute appendicitis.

Scientists at the Mayo Clinic (Scottsdale, AZ, USA) examined 105 patients between the ages of 15 and 69 who underwent an appendectomy within three days after having an abdominal CT. Results of the CT scans were compared with the actual severity of acute appendicitis. The study demonstrated that CT gave results correlating with the actual condition of the appendix in acute appendicitis. These results were utilized to devise a model that could, when used in combination with additional CT measurements, help determine the best treatment course in patients strongly suspected of having acute appendicitis.

The researchers concluded that the study accomplished the goal of devising a predictive model that, in the near future, may help stratify such patients based on prediction of the histologic severity of the disease. It provides a foundation for a subsequent prospective trial that will use predictive stratification that will determine the need for and timing of operative intervention.

The study was published in the December 2004 issue of the journal The Archives of Surgery.
