Abstract:
Objective To evaluate the clinical significance of the diameter of the esophageal hiatus on multislice spiral CT(MSCT)and to present the MSCT manifestations of esophageal hiatus hernia (EHH).Methods(1)The distance between diaphragmatic crura(DDC),which indicated the diameter of esophageal hiatus,was measured in 140 normal adult patients on their thoracic and/or abdomenal CT images.(2)The DDC of 56 patients with EHH diagnosed by barium examination was measured on MSCT, and the MSCT findings were analyzed retrospectively.Results(1)The DDC of 140 normal adult cases were(13.44?4.41)mm on average and increased with age.The mean DDCs of patients under the age of 59 year-old(80 cases)and over 60-year-old(60 cases)were 11.03?2.10 mm and 16.67?4.64 mm respective]y,there was a significant difference(t=8.762,P
