Objectives To investigate the diagnosis of esophageal and gastric varices between multi-slice spiral (MS) CT portography and endoscopy. Methods Fifty-seven patients clinically diagnosed with portal hypertension were underwent MSCT portography by LightSpeed 16 CT scanner. The endoscopic examinations were also carried out in those patients within 3 days. Results The CT portography revealed that 51 patients with esophageal or gastric varices, including 39 patients with both gastric fundal varices and esophagus varix, 9 patients with only esophageal varices, 3 patients with gastric body and gastric fundal varices. While 46 patients were found by endoscopy to have esophageal or gastric varices, including 24 patients with both esophageal and gastric varices, 5 patients with only gastric varices and 17 patients with only esophageal varices. Conclusion The MSCT portography can clearly demonstrate the esophageal and gastric fundal varices, as well as major collateral vessels in portal hypertension patients. There was a certain false positivity in MSCT portography, and they can be used as supplement tests to endoscopy in the diagnosis of esophageal varices. The MSCT portography was more sensitive than endoscopy in diagnosis of gastric varices, and could visualize the para esophageal and para-gastric varices that were not visible to the endoscopy.
