超声测量胰腺钩突角在诊断胰头占位性病变中的临床意义

Clinical significance of measuring angel of lesser pancreas in diagnosis of neoplasm in the head of pancreas

目的 探讨超声测量胰腺钩突角 (angeloflesserpancreas ,ALP)在诊断胰头占位性病变中的临床价值。方法 超声测量 41例胰头肿瘤患者和 5 2例正常人的ALP ,并将其分为 3组 :A组 ,超声发现胰头有占位性病变 3 2例 ;B组 ,超声未发现而CT或MRI发现胰头有占位性病变 9例 ;C组 ,为正常对照组 5 2例。结果 A、B、C组ALP分别为 83°± 9° ,78°± 9° ,43°± 5° ,A、B两组的ALP明显大于C组的ALP(P <0 .0 1)。C组的ALP均 <60° ,而A组和B组的ALP均 >60°。结论 超声检查发现ALP增大是提示胰头占位性病变的敏感指标 ,有必要进一步行强化CT或MRI检查。

Objective To evaluate the clinical significance of measuring angel of lesser pancreas(ALP) by ultrasound in diagnosis of neoplasm in the head of pancreas.Methods ALP was measured by ultrasound in 41 cases of pancreatic neoplasm,and in 52 normal cases as contrast.All of the cases were divided into three groups: group A,32 cases which were proven having mass in the head of pancreas by ultrasound; group B,9 cases which were discovered mass in the head of pancreas by CT or MRI,but not diagnosed by ultrasound; group C,52 cases as contract without presence of any mass in the head of pancreas.Results The mean value of ALP in group A,group B and group C was 83°±9°,78°±9°,and 43°±5°, respectively.The angel in group A and group B was significantly wider than that in group C (P< 0.01 ).Group C showed ALP<60°,while group A and B showed ALP>60°.Conclusions The widing of ALP by ultrasound is a sensitive sign for mass in the head of pancreas.
