摘要
目的 回顾性分析多层螺旋CT(MSCT)诊断腹部闭合性创伤患者的诊断效能.方法 回顾性分析河南电力医院 2021 年 3 月至 2022 年 3 月接诊的 86 例疑似腹部闭合性创伤患者,均行MSCT检查,对比CT平扫、CT增强的扫描结果.结果 手术病理结果 86 例中阳性 80 例,阴性 6 例.CT增强结果阳性 78 例,阴性 8 例;CT平扫结果阳性 68 例,阴性 18 例;CT增强诊断符合率(95.35%)高于CT平扫(74.42%),差异有统计学意义(P＜0.05);CT增强敏感度、准确度、特异度 96.25%、83.33%、95.35%高于CT平扫的 78.75%、16.67%、74.42%,差异有统计学意义(P＜0.05);手术病理结果肋骨骨折 13 例,损伤脾脏 24 例,损伤肾脏 10 例、损伤胰腺 11 例、肺挫伤 13 例、损伤肝脏 9 例.CT增强诊断损伤类型符合率为 97.50%,CT平扫为 85.00%,差异有统计学意义(P＜0.05);CT增强成像I级率、Ⅲ级率优于CT平扫,差异有统计学意义(P＜0.05);CT增强Ⅱ级低于CT平扫,差异无统计学意义(P＞0.05).结论 MSCT用于诊断腹部闭合性创伤患者,特别是CT增强扫描的诊断效能较高,敏感度、特异度、准确率较高,短时间内即可出具扫描结果,为抢救腹部闭合性创伤患者争取了宝贵时间,为后续制定治疗方案提供科学的参考依据.
Abstract
Objective To retrospectively analyze the diagnostic efficiency of multislice spiral CT(MSCT)in patients with abdominal closed trauma.Methods Eighty-six suspected cases of abdominal closed trauma admitted to Henan Power Hospital from March 2021 to March 2022 underwent MSCT examination,and the results were compared with CT plain scan and CT enhancement.Results Surgical pathology results:80 positive cases out of 86,and 6 negative cases.CT enhancement results:78 positive cases,8 negative cases;CT plain scan results:68 positive cases,18 negative cases.The diagnostic conformity rate of CT enhancement(95.35%)was higher than that of CT plain scan(74.42%),with statistical significance(P＜0.05);the sensitivity,accuracy,and specificity of CT enhancement were 96.25%,83.33%,and 95.35%,respectively,which were higher than those of CT plain scan(78.75%,16.67%,and 74.42%,respectively),with statistical significance(P＜0.05).Surgical pathology results:13 cases of rib fractures,24 cases of spleen injuries,10 cases of kidney injuries,11 cases of pancreatic injuries,13 cases of lung contusions,and 9 cases of liver injuries.The diagnostic conformity rate of CT enhancement for injury types was 97.50%,compared to 85.00%for CT plain scan,with statistical significance(P＜0.05);CT enhancement imaging rates for Grade Ⅰ and Grade Ⅲ were superior to CT plain scan,with statistical significance(P＜0.05);CT enhancement Grade Ⅱ was lower than CT plain scan,with no statistical significance(P＞0.05).Conclusion MSCT is highly effective in diagnosing abdominal closed trauma,especially CT enhancement scanning,which exhibits higher sensitivity,specificity,and accuracy,providing valuable time for rescuing patients with abdominal closed trauma and offering scientific reference for subsequent treatment plans.
