Abstract
With the avent of newer image modalities, various normal measurement for the common bile duct (CBD) have been reported. Computed tomography (CT) is rapidly gaining acceptance as a noninvasive tool in the measurement of the CBD diameter. If the CBD cannot be adequately evaluated sonographically, CT can be helpful in visualizing of the CBD. With the development of CT scanners having improved spatial and contrast resolution as well as faster scanning times, the CBD seems to be seen more frequently and its diameter appear to be larger than the previously reported values. This study was conducted to determine the visibility rate and mean diameter of the CBD with high resolution CT. Diameter of the CBD was measured in 158 persons with visible CBD among 280 persons and the following results were obtained: 1. 158 persons (56.4%): had visible CBD in 280 persons. 2. There were 90 male (57%) & 68 female (43%) and their age ranged from 20 to 79 years. 3. 145 persons (54.7%) had visible CBD in noncholecystectomized persons. The mean diameter was 5.3 ± 1.73 mm. 4. 13 persons (86.7%) had visible CBD in cholecystectomized persons. The mean diameter was 6.4 ± 2.03 mm. 5. There was gradual dilatation of the CBD diameter with age. 6. The CBD was located in anterior (87.3%), lateral (5.7%), or medial (7.0%) to the inferior vena cava.;담도계질환은 최근 전산화단층촬영술과 같은 영상기계의 발달로 비침해적이며 간편하고 신속하게 진단할 수 있게 되었다. 전산화단층촬영의 영상 분석 판독력의 급진으로 담도계질환중에서도 총수담관질환의 진단에 획기적인 발전을 보여주었을 뿐만 아니라 예후 판정과 치료에도 많은 도움을 주고 있다. 저자는 복부 전산화단층촬영을 시행한 성인 280명중 총수담관을 관찰할 수 있었던 158명을 대상으로 총수담관의 직경을 계측하여 다음과 같은 결론을 얻었다. 1. 총수담관을 관찰할 수 있었던 예는 280예중 158예(56.4%)였으며, 남자 90예(57%), 여자 68예(43%)였고 연령분포는 20∼79세였다. 2. 담낭절제술을 시행치 않은 예에서 총수담관이 관찰된 예는 145예(54.7%)였으며, 직경은 5.3±1.73mm였다. 3. 담낭절제술을 시행한 예에서 총수담관이 관찰된 예는 13예(86.7%)였으며, 직경은 6.4±2.03mm였다. 4. 총수담관의 직경은 연령이 증가함에 따라 점차 확장되었다. 5. 총수담관이 하대정맥 전방에 138예(87.3%), 외측에 9예(5.7%), 내측에 11예(7.0%)위치하였다.
