The reasons for failure of endoscopic retrograde cholangio-pancreatography in patients with jaundice.
The results of 100 attempts at endoscopic retrograde cholangio-pancreatography (ERCP) performed in patients with jaundice have been reviewed. The examination provided a diagnosis in 75% of cases. The reason for failure to cannulate the correct duct was obstruction at the lower end of the common bile duct in 15 patients and distortion of the duodenum in seven. There was no cause for the failure in only two patients. Even with a perfect technique it will not always be possible to obtain an endoscopic cholangiogram. However, as the commonest cause of failure is obstruction, transhepatic cholangiography should usually succeed when ERCP fails.
