The pilot study of contrast-enhanced ultrasound in assessing necrosis of acute pancreatitis

摘要: 目的：探讨超声造影（CEUS）在急性胰腺炎（AP）诊断及评价胰腺血流灌注方面的应用价值。方法：对34例AP病例的CEUS图像进行分析总结，以Balthazar CT平扫分级为标准对其进行分型，并与增强CT（CECT）结果相对比。结果：34例胰腺炎病例，CEUS诊断轻症急性胰腺炎（MAP）9例，重症急性胰腺炎（SAP）25例，其中AP伴散在小灶状坏死12例，AP伴片状坏死灶13例。CECT诊断MAP 11例，SAP 23例。CEUS与CECT相比在诊断AP分型上差异无统计学意义（P=0.595，χ2=0.283）。结论：CEUS既可诊断AP，又可评价胰腺血流灌注情况，在临床应用中有广阔前景。Abstract: Objective: To explore the value of CEUS (contrast-enhanced ultrasound) in diagnosing AP (acute pancreatitis) and evaluating pancreatic blood perfusion.Method: We analyzed and summarized the characteristics of CEUS images about thirty-four AP cases, and classified them into two types according to the standards of Balthazar' CT grading system, and then compared them with CECT (contrast-enhanced computer tomography) results.Result: Of thirty-four AP cases examined by CEUS, nine cases of MAP (mile acute pancreatitis) were diagnosed, and twenty-five cases of SAP (severe acute pancreatitis) were diagnosed, including twelve AP cases with small necrosis and thirteen AP cases with flaky necrosis. Eleven MAP cases and twenty-three SAP cases were diagnosed by CECT, respectively. There was no statistical difference between CEUS and CECT in diagnosing AP types (P=0.595, χ2=0.283).Conclusion: CEUS can not only diagnose AP, but also evaluate pancreatic blood perfusion, and has good prospects in clinical application.
