Abdominal examination for MRCP PACES

The patient was a middle-aged man lying comfortably in bed. He was of average height. His weight was difficult to judge as his abdomen was distended but there appeared to be loss of weight as his extremities looked thin.
On examination of his head his sclerae were icteric making the trainee immediately suspect that the patient had liver disease. There were multiple telangiectasia over his face in keeping with hepatocellular failure. There was bilateral parotid enlargement which made the trainee suspect that the aetiology of the condition was alcohol abuse.
On examination of the hands there was palmar erythema another feature of hepatocellular failure. He had Dupuytren’s contracture, which was another feature that would suggest the aetiology of the condition was alcohol abuse.
He had multiple spider naevi over his upper chest a further indication of hepatocellular failure. There was no gynaecomastia and the distribution of hair growth over his chest was normal.
The abdomen was distended and the distension was greatest in the flanks this made the trainee suspect that the patient had ascites. There were visible veins on the anterior abdominal wall and the direction of blood flow was from caudal to cranial. This suggested that the patient had portal hypertension.
On palpation of the abdomen no lumps or organomegaly were detected. Percussion demonstrated a horseshoe shaped area of dullness and shifting dullness confirming the trainee’s earlier suspicion that the patient had ascites. Auscultation did not reveal any abnormality.
At this point the trainee was asked to employ the technique of “dipping” and with this technique she was able to note that the liver was enlarged three finger breadths below the costal margin but the enlargement was not detected by routine palpation because of the presence of ascites. This was an important learning point. In the presence of ascites always employ “dipping” to detect organomegaly or masses.
Diagnosis:
Features of chronic hepatocellular failure
Features of portal hypertension
Hence clinical diagnosis of cirrhosis of the liver
Aetiology probably alcohol abuse
Revision Tips
Learn the clinical features of cirrhosis of the liver (the features of hepatocellular failure, features of portal hypertension) the causes of cirrhosis of the liver and clinical clues to the causes of cirrhosis of the liver (ACES for PACES pages 305-306)
Learn the technique of “dipping” (ACES for PACES page 273)
