총담관확장 및 결석진단에 있어서의 초음파와 ERCP 의 비교분석
정영기(Young Ki Chung),서동룡(Dong Ryong Seo),장정표(Jeong Pyo Jang),주홍(sung Yub Yeo),여승엽(Hong Joo) 대한소화기학회 1987 대한소화기학회지 Vol.19 No.1
N/A ERCP was performed in 107 patients who underwent right upper quadrant sonography at Maryknoll Hospital in Pusan from Jan. 1985 to Feb. 1987. ERCP showed biliary tree appeared in 83 cases of the total 107 cases (78%). The time lapse between the performance of the ultrasound and ERCP did not exceed 7 days in 55 cases of the 83 cases mentioned above. These 55 cases make up this study population. In this study, we assessed the presence or absence of choledocholithiasis and the size of the common bile duct. The results are as follows: 1) Ultrasound was not accurate in the diagnosis (sensitivity, 41%) or exclusion (value of a negative study, 77%) of choledocholithiasis. 2) In the postcholecystectomy patient population, ultrasound assessment of biliary duct size is not a useful predictor of biliary disease (value of a positive diagnosis, 40%). As a conclusion, when biliary diseases are suspected, especially for syptomatic postcholecystectomy patients, we recommand that as the diagnostic modality ERCP as well as ultrasound should be performed necessarily.
