The results were as follows: 1. ultrasonographic findings of the total of127 cases are normal in 41(32.3%) cases, and abnormal in 86(67.6%) cases. 2. Clinical diagnosis of normalultrasonographic cases is unknown in 15(36.6%) cases, hepatitis in 10(24.3%) cases, pancreatitis in 6(14.6%) case,enterocolitis in 5(12.1%) cases, acute gastritis in 3(7.5%), acute pyelonephritis in 1(2.4%) case, andclonorchiasis in 1(2.4%) case. 3. Pathological diagnosis of 50 cases out of 86 cases of abnormal ultrasonographyis GB stone in 36(72.0%) cases, pancreatic cancer in 5(10.0%) cases, hepatoma in 3(6.0%) cases, CBD stone in4(8.0%) cases, pancreatic pseudocyst in 1(12.9%) case and liver abscess in 1(2.0%) case. 4. Diagnostic accuracy ofultrasonography of GB stone was 91.7%, false positive 2.8% and false negative 6.6%. 5. Ultrasonography has theadvantage of noninvasiveness and easy performance, but the diagnostic accuracy of ultrasonography alone was low.Ultrasonography is considered as a good screening and complemntary method for evaluation of right upper quadrantpain.
