超声观察急性胰腺炎时左肾旁前间隙的准确性及临床意义

The accuracy and clinical significance of left anterior pararenal space abnormality observed by ultrasound in acute pancreatitis

目的 探讨超声观察急性胰腺炎 (AP)时左肾旁前间隙 (LAPS)的准确性及其临床意义。方法 回顾本院 3年 62 7例AP患者超声检查资料与临床资料 ,其中 10 0例行 10 8次CT检查。结果 在10 8例次有同期超声及CT检查的病例中超声诊断LAPS积液的敏感性、特异性及准确性分别为 65 .0 %、92 .1%及 87.1% ,诊断LAPS坏死组织则分别为 75 .0 %、10 0 %及 99.1%。 62 7例临床资料表明轻症胰腺炎组LAPS积液及坏死组织的出现率为 11.8%和 0 .2 % ;而重症胰腺炎组则分别为 44.0 %及 12 .0 %。有LAPS积液组平均住院日为 2 9.0d ,而无LAPS组为 15 .5d。结论 LAPS是AP时最常受累的部位之一 ,LAPS病变与AP的轻重及住院时间长短有关 ;超声能较准确地反映LAPS病变 ,对指导治疗方式及手术入路选择有重要意义。

Objective To determine the accuracy and clinical significance of left anterior pararenal space(LAPS) observed by ultrasound(US) in acute pancreatitis(AP).Methods Six hundred and twenty seven AP patients were studied retrospectively. All patients were examined by US and 100 cases accepted 108 times CT scan.Results The sensitivity, specificity and accuracy of US for detecting LAPS fluid collection were 65.0 %, 92.1 %, 87.1 % respectively,and were 75.0 %,100%, 99.1 % for detecting LAPS necrosis. In mild AP, the emergence rate of LAPS fluid collection and necrosis were 11.8 % and 0.2 % while in severe AP were 44.0 % and 12.0 %. The hospital stay with and without LAPS fluid collection was 29.0 days and 15.5 days respectively.Conclusions LAPS was one of the most common site of AP fluid collection. The LAPS abnormalities are proportional to the hospital stay and the severity of AP, these can observed by ultrasound correctly.
