The pattern of liver diseases in Singapore. An autopsy study

This study is based on an analysis of 1839 consecutive necropsies. Liver diseases are common in Singapore. Of particular importance are cholelithiasis, cirrhosis and primary carcinoma of the liver. Gallstones are mainly of the pigment variety and a significant proportion are present in the bile ducts. The multiracial composition of the population is reflected in a difference in the pattern of liver diseases among the different ethnic groups. Indians are found to have more alcoholic hepatitis and cirrhosis which are often of the micronodular type, while the Chinese have significantly more macronodular cirrhosis and hepatocellular carcinoma. Clonorchiasis and schistosomiasis are confined to the immigrant Chinese. The pattern of liver diseases is changing. Cholangitis and cholangitic abscesses as a result of cholelithiasis are becoming more common while amoebic abscesses and hepatic ascariasis are definitely on the decline. This is attributable to improved sanitary conditions.
