Abstract
Endoscopic ultrasonography (EUS)-a combination of endoscopy a.nd ultrasonography was one of the most useful tools for diagnosis of digestive system diseases. This technique was known to be very effective in the assessment of depth of invasion in gastric cancer and in pancreatico-biliary diseases. We performed EUS in 589 patients with upper gastrointestinal and pancreatico-biliary tract lesion prior to surgery for past 22 months and examined the diagnostic accuracy of EUS, respectively. The results were compared to surgical histology in esophagus and stomach cancer,to concordance witb endoscopic retrograde cholangiopancreatography(ERCP ) results for pancreaticobiliary diseases. 1) In 589 patients diagnosed with EUS, the mean age of the patients was 55.9 years with a male to female ratio of 1.7: 1. 2) Patients were divided into three groups; post-upper gastrointestinal endoscopy, post ERCP and undiagnosed with other diagnostic tools. 3) Among post-upper gastrointestinal endoscopy, 64 cases were operated due to esophageal and gastric cancer and then compared to surgical histology. After compared, EUS accuracy on depth of invasion was 78.1% and sensitivity and specificity on lymph node metastasis in gastric cancer were 76.9% and 74.3%, respectively. 4) In post-ERCP cases, EUS results were compared to ERCP results and then concordance rate was 95.4%. 5) In undiagnosed cases, EUS was performed and results were reported.
