Correlation of Abnormal CT Scan Findings of Upper GI Tract with Upper Endoscopy

Abstract

Purpose: To ascertain the significance of abnormal findings on CT scan related to upper GI tract with a subsequent endoscopy in an outpatient setting. Methods: All patients that underwent an upper endoscopy for evaluation of abnormal CT findings at an outpatient endoscopy center were reviewed. Findings on endoscopy and biopsies were compared with the original findings on CT scan that necessitated the endoscopy.Table: Table. CT and EGD findings, commonTable: Table. Correlation when “other CT findings” are reportedResults: A total of 70 patients over a ten year period (2004 to 2012) were reviewed. Age of patients ranged from 32-92 years. 39 (56%) were females, 31 (44%) were males. All abnormal endoscopic findings were biopsied and verified with pathology. Common abnormalities reported in CT include esophageal wall thickening in 15 [21%], gastric wall thickening in 39 [56%] and duodenal wall thickening in 7 [10%]. 9 [13%] had other findings including 3 with portal HTN, 4 with gastric mass, and 2 with liver metastasis. The CT findings co-related with abnormal EGD in 59 out of 70 patients [84%]. Conclusion: Majority of patients (84 %) with abnormal findings related to upper GI tract on CT had significant relevant EGD findings. Therefore, all abnormal CT's warrant further investigation with EGD.
