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 ALP60°,while group A and B showed ALP60°.Conclusions The widing of ALP by ultrasound is a sensitive sign for mass in the head of pancreas.
