Abstract
The diagnosis of. gallbladder and biliary c.alc-uli has become much more accurate because of both changes in the conventional methods and in the introduction of new methods. The diagnostic techniques have multiplied; non-
invasive methods have been introduced and well-established procedures have been modified to encompass treatment.
However, it is quite clearly; the least traumatic, least expensive and most specific methods should be used initially(Kreel, 1981) i (Table 6).
In the nonemergent patient, it is suggested that the single-dose O.C.G be generally the initial study, and that subsequent ultrasound examination be performed if there is non-visualization or poor visualization of the gallbladder.
If gallstones are identified, further diagnostic procedures relative to gallbladder would seem unnecessary (Oaprini, 1979 and Baddeley, 1980). If ultrasound examination is equivocal then I.V.C can be used (Baddeley, 1980), In the optimal situation, the failure of identification of dilated bile ducts on sonqgrams should eliminate the invasive percutaneous cholongiogram (Caprini, 1979)•
