[A study involving early carcinomas of the gall bladder].

In recent years, with the development of diagnostic procedures, the number of cases of early carcinoma of the gall bladder has been seen to gradually increase. In this paper, 8 cases of early gall bladder carcinoma have been evaluated, using a diagnostic approach. Cholecystolithiasis was the complication in 6 cases, and abdominal pain was seen as the most common symptom. Findings by various image diagnoses, such as ultrasonography, DIC, ERCP, and CT scan are described and discussed with a review of literature. Ultrasonography was considered to be the most useful tool for the detection and diagnosis of an early carcinoma of the gall bladder. A survey is thought to be required, involving the cases that have accumulated throughout the entire nation.
