Summary
The ultrasonic echotomography is discussed about its diagnostic results on cholelithiasis, cancers of bile ducts and pancreas.
Cholelithiasis is ascertained by almost 90 per cent of probability. Cancers of bile ducts and pancreas in this report are certainly indicated in all cases as well by the criteria.
Gallstones are certainly detectable in the gallbladder, when grown to over 0.7 cm in size. Gallbladders may be visualized in all probablity, when swollen to over 35 ml, and common bile ducts may be indicated as well, when dilated to over 25 cm wide.
The diagnosis by echotomograms taken under variing sensitivities is reasonable and highly reliable for the interpretation of diseases in the right hypochondrium.
