The purpose of the study was to assess the clinical value of ultrasonography (US) and percutaneous transhepatic cholangiography (PTC) in the workup of obstructive jaundice in Yaoundé. From 3,000 ultrasonographic studies done between September 1987 and February 1990, the authors drew 37 cases of obstructive jaundice. 22 of them were explored with both US and PTC. The cause of obstruction was tumor for 14, inflammation or malformation for 4 and biliary stone for 4. US could predict the cause in 55 p. cent of cases and PTC in 77 p. cent of cases. PTC was particularly helpful in case of non tumoral causes. The authors conclude that, in their setting where computed tomography is scarce and expensive, the combination of both US and PTC is rewarding, when the problem is the determination of the nature of obstruction.
本研究的目的是评估超声检查（US）和经皮肝穿刺胆管造影（PTC）在雅温得阻塞性黄疸检查中的临床价值。在1987年9月至1990年2月期间进行的3000例超声检查中，作者选取了37例阻塞性黄疸病例。其中22例同时接受了US和PTC检查。阻塞原因是肿瘤的有14例，炎症或畸形的有4例，胆结石的有4例。US能在55%的病例中预测病因，PTC能在77%的病例中预测病因。PTC在非肿瘤性病因的情况下特别有帮助。作者得出结论，在他们所在地区，计算机断层扫描稀缺且昂贵，当问题是确定阻塞的性质时，US和PTC联合使用是有价值的。
