We have examined 71 patients with liver diseases using the ultrasonic laparoscope (US-lapa) with electronic linear scanning system, which was designed and develoved by Toshiba CO. and Machida Co.. Twenty three patients with gallbladder diseases were found and a comparative study of US-lapa with extracorponeal ultrasonography (US), was carried out. US-lapa showed more fine and clear, visualization than US. The 3 layers of the gallbladder wall and number, the character, and the stalk of small polypoid lesions of gallbladder were clearly detected. Furthemore, there were advantage that the laparoscopic findings of gallbladder could be obtained simultaneously and the scanning from any direction could be performed. In conclusion, US-lapa was considered to be of great value in the diagnosis and the fine observation of gallbladder disease.
