Liver disease in rural Tanzania--a diagnostic approach.

In a prospective study on the aetiology of liver disease and its diagnostic approach in a District hospital in rural Tanzania, 48 consecutive patients with evidence of liver disorders were investigated by physical examination, biochemical tests, laparoscopy and histology. Liver cirrhosis (posthepatic, alcoholic) was found in 31%; non cirrhotic alcoholic liver disease in 15%; viral, bacterial and protozoal liver disorders in 33%, and neoplastic liver changes in 21% of all patients. Clinical impression alone coincided with the final diagnosis in 40% of all cases. This figure was increased to 46%, when haematological and biochemical results were included, and to 71%, when laparoscopy (without histology) was used in addition. Laparoscopy was particularly decisive in the diagnosis and further management of cirrhosis, liver abscess and neoplastic liver disorders. The additional information obtained from histology led to the final diagnosis. Histology was specially useful for the diagnosis of alcoholic liver disease, tropical splenomegaly syndrome and non specific reactive hepatitis. The usefulness of laparoscopy as a diagnostic tool in a district hospital is discussed.
