Ultrasonography for their basic problem was done. All these patients underwent surgery. Operative findings were compared with preoperative ultrasonography findings and the accuracy of ultrasonography in hepatobiliary diseases was evaluated. In 34 cases, ultrasonographic findings as compared to operative findings were inaccurate while in 55 patients these were comparable to operative findings. Generally accepted overall accuracy rate of ultrasonography in hepatobiliary diseases is 86%. Accuracy rate in this study was only 66% showing that ultrasonography is an operator dependant procedure
