Ultrasound combined with computed tomography in pancreatic cancer

To investigate the diagnostic value of ultrasound combined with computed tomography (CT) in pancreatic cancer.

312 patients with pancreatic lesions treated in the Affiliated Hospital of Qingdao University were retrospectively analyzed, including 217 patients definitely diagnosed with pancreatic cancer and 95 patients diagnosed with pancreatitis. A hundred and one patients with ultrasonic diagnosis were enrolled into the ultrasound group, 98 patients with CT diagnosis were enrolled into CT group, and 113 patients undergoing ultrasound combined with CT diagnosis were enrolled into combined group. The diagnostic value of the three examination methods in pancreatic cancer was compared and analyzed.

The sensitivity, accuracy and negative prognostic value in the combined group were higher than those in ultrasound group and CT group (p<0.05), but the missed diagnosis rate was lower than those in ultrasound group and CT group (p<0.05). In the combined group, the sensitivity was higher than those in the ultrasound group and the CT group, the accuracy and negative predictive value were higher than those in the ultrasound group, and the missed diagnosis rate was lower than those in the ultrasound group and the CT group, displaying statistically significant differences (p<0.05).

Ultrasound combined with CT can make up for the deficiency of each other and effectively improve the predictive value in the diagnosis of pancreatic cancer, which can be used as an effective examination method in the diagnosis of this disease.
