To determine the diagnostic Accuracy of Focused Assessment Sonography for Trauma (FAST) and repeated FAST in the patients with blunt abdominal trauma.
In this retrospective study we collected the data of all patients from September 2007 to July 2011 with gastrointestinal injury. The intraoperative outcome was compared with FAST technique and the repeated or delayed sonography.
A total number of 1550 patients with blunt abdominal trauma underwent FAST in a period of 4 years in our hospital. Eighty-eight (5.67%) patients were found to have gastrointestinal injury after exploratory laparotomy. Fifty-five (62.5%) patients had isolated gastrointestinal injury and 33 (37.5%) patients had concomitant injury to the other solid organs. In those with isolated gastrointestinal injury, the sensitivity of FAST was 38.5%. Repeated ultrsonography was performed in 34 patients with false negative initial FAST after 12-24 hours. The sensitivity of repeated ultrasonography in negative initial FAST patients in detection of gastrointestinal injury was 85.2% (95% CI, 68.1%, and 94.4%).
Repeated sonography after 12 to 24 hours in patients with negative initial FAST but sustain abdominal symptom can facilitated a diagnosis of GI tract injury and can be as effective method instead of Computed tomography in developing country.
旨在确定创伤重点评估超声（FAST）和重复 FAST 在钝性腹部创伤患者中的诊断准确性。
在这项回顾性研究中，我们收集了 2007 年 9 月至 2011 年 7 月期间所有胃肠道损伤患者的数据。将术中结果与 FAST 技术和重复或延迟超声进行比较。
在我院 4 年期间，共有 1550 例钝性腹部创伤患者接受了 FAST。88 例（5.67%）患者在剖腹探查后发现胃肠道损伤。55 例（62.5%）患者存在孤立性胃肠道损伤，33 例（37.5%）患者存在其他实体器官的合并损伤。在孤立性胃肠道损伤患者中，FAST 的敏感度为 38.5%。在最初 FAST 检查为阴性的 34 例患者中，12-24 小时后重复超声检查。在最初 FAST 检查为阴性的患者中，重复超声检查对胃肠道损伤的敏感度为 85.2%（95%CI，68.1%，94.4%）。
在最初 FAST 检查为阴性但持续存在腹部症状的患者中，12 至 24 小时后进行重复超声检查可以促进对胃肠道损伤的诊断，并且可以作为发展中国家的有效方法替代计算机断层扫描。
