摘要
目的探讨闭合性胃肠损伤穿孔主要CT表现与外伤后时间的相关性。方法搜集54例经手术证实的闭合性胃肠损伤穿孔患者的临床和CT检查资料,根据外伤后时间段分组,回顾性分析外伤至CT检查的时间和其主要CT表现的相关性。结果外伤8h前后CT对气腹的显示率差异有统计学意义(P<0.05)。CT显示腹腔积液总的敏感性较高(88.9%)。结论外伤后行CT检查的时间与CT气腹表现密切相关。部分患者于伤后8h内CT检查可能表现为气腹征阴性。对早期CT检查仅表现为腹腔积液等非特异性征象的患者,需结合临床及时复查确诊、以免延误手术治疗时机。
Objective To study the association between the time from injury to examination and CT manifestations for the patients with gastric and bowel closed injury perforation.Methods Clinic materials and CT features of 54 patients with bowel and gastric closed injury perfora tion confirmed by surgical operation were collected.The patients were divided into several groups according to the time from injury to CT exam.The association between the time from injury to exam and CT manifestations for the patients was retrospectively analyzed.Results There was significant difference between the display rate of pneumoperitoneum on CT with the patients who were taken examination within 8 hours and those beyond 8 hours(P<0.05).Generally,the display rate of ascites on CT was relatively higher(88.9%).Conclusion There was significant the association between the time from injury to exam and CT manifestations of pneumoperitoneum.CT feature of pneumoperitoneum in parts of the patients may be negative within 8 hours after injury.Aimed at the patients with only non-characteristic manifestations such as ascites on early CT exam,intimately observed and repeat CT examination should be done to confirm diagnosis and to avoid the chance of surgery treatment delayed.
